Abstract: Increased consumer interest in healthier, clean label food products has

increased research efforts on the production of functional meat products with

increased bioactive compounds found in plants. Despite being good sources of

high-quality protein and important micronutrients, traditional meat products are

commonly criticized to containing high saturated fats, cholesterol and synthetic

additives, in addition to the absence of dietary fiber and natural antioxidants. This

review provides a critical analysis of the more recent developments in the addition

of different plant-derived bioactives, such as polyphenols, carotenoids, dietary

fibers, essential oils and plant protein hydrolysates, to meat-based matrices. These

compounds have both techno-functional properties: as natural preservatives, they

inhibit lipid oxidation, protein oxidation and microbial spoilage, thereby

prolonging product shelf life, as well as having health-promoting properties,

including

antioxidant,

anti-hypertensive,

anti-inflammatory,

and

hypocholesterolemia properties. Nevertheless, significant difficulties remain, such

as the formation of off-flavors, unwanted color changes (e.g. browning or fading),

textural deterioration and decreased overall consumer acceptability in cases of

bioactive compound addition beyond optimal levels, which are mostly 0.5-5%

w/w. The new encapsulation technologies like microencapsulation, nanoemulsions

and edible coatings are identified as the effective methods to conceal the

undesirable sensory properties, to control the release of bioactives and retain their

functionality even during thermal treatment and storage. The future research needs

to focus on human intervention studies to support health assertions,

standardization of extraction and incorporation procedure to provide batch-to-

batch consistency and use of green technology to produce at sustainable levels.

Moreover, the lack of definite regulatory frameworks regarding the labelling of the

product of functional meat is also a major obstacle to commercial translation. To

sum up, strategic fortification of meat products with plant-based bioactive

compounds is a feasible and promising formulation approach to radicalize

conventional meat into functional foods that can satisfy the demands of modern

consumers regarding their sensual pleasure and health promotion, as long as

challenges linked to formulations can be overcome with new processing

technologies.

1. Introduction

Meat has been known to be a nutritionally rich food; it is a source of high-quality protein,

bioavailable heme iron, zinc, selenium, and B vitamins (Pereira & Vicente, 2013).

Nevertheless, recent 20 years have seen an accumulation of epidemiological data about the

risks of colorectal cancer, cardiovascular disease, and type 2 diabetes associated with excess

intake of processed meat (Bouvard et al., 2015; Micha et al., 2010). In 2015, the

International Agency on Research on Cancer characterized processed meat as being

carcinogenic to humans (Group 1), which has triggered a rush to reformulate conventional

meat products.

At the same time, the demand of consumers in the so-called clean label products, i.e., the

products without synthetic preservatives, artificial colorants, and other chemicals-

sounding ingredients has increased significantly (Asioli et al., 2017). Foods prepared the

traditional way use synthetic preservatives like sodium nitrite, butylated hydroxyanisole

(BHA) and butylated hydroxytoluene (BHT) to preserve, maintain their color, and to

ensure safety. Substitution of these multifunctional additives with natural ones is a big

technological challenge.

Bioactive compounds obtained through plants have become the most promising

candidates to overcome this challenge (Shah et al., 2019). Millennia-old plants have

developed complex secondary metabolites of phenolic compounds, terpenes and

glucosinolates as defense systems against oxidative stress and pathogens. The same

compounds are highly antioxidant, antimicrobial, and anti-inflammatory in their use in

food matrices (Fraga et al., 2019). The objective of this review is to synthesize the existing

information on the production of functional meat products supplemented with plant-

derived bioactive compounds, where the emphasis will be on:

(1) the key classes and sources of plant bioactive

(2) the mechanisms of action in meat products

(3) enrichment technologies

(4) the effects on product quality and safety

(5) the sustainability aspects such as by-product

2. Major Classes of Plant Bioactive Compounds

2.1 Polyphenols

The most chemically diverse and largest group of plant secondary metabolites is the

polyphenols, which have aromatic rings with one or more hydroxyl groups (Table 1).

They have simple phenolic acids to highly polymerized tannins as the range of their

molecular structures, and a correspondingly varied range of functional properties in meat

systems.

2.1.1 Phenolic Acids

The simplest subclass of polyphenols is the phenolic acids which are derivatives of benzoic

and cinnamic acid. The hydroxybenzoic acids (gallic, protocatechuic and vanillic) have a

C6-C1 structure whereas the hydroxycinnamic acids (caffeic, p-coumaric and ferulic) have

a C6-C3 structure (Robbins, 2003). Caffeic acid, which is abundant in coffee and

blueberries, exhibits a strong antioxidant effect by hydrogen atom transfer (HAT) and

single electron transfer (SET) processes. The most common phenolic acid in cereal grains

is ferulic acid which possesses other UV absorption characteristics and can be used to

prevent the degradation of meat pigments caused by photodegradation (Kumar and

Pruthi, 2014).

2.1.2 Flavonoids Flavonoids

have a similar C6- C3-C6 skeleton. Notable subclasses are flavonols (quercetin,

kaempferol), flavones (luteolin), flavan-3-ols (catechin), and anthocyanidins (cyanidin).

The example of structure-activity relationship in antioxidant activity is Quercetin: the 3,4-

dihydroxy B ring allows effective delocalization of electrons and the 2,3-double bond

conjugated with the 4-oxo group promotes resonance stabilization (Rice-Evans et al.,

1996). Epigallocatechin-3-gallate (EGCG) of green tea includes a gallate ester, which

significantly increases antioxidant and protein-binding functions (Nagle et al., 2006).

Hydroxytyrosol and Olive-Derived Compounds. 2.1.3 Hydroxytyrosol and Olive-

Derived Compounds.

Hydroxytyrosol (3,4-dihydroxyphenylethanol) is one of the most powerful natural

antioxidants that have been found. It is nearly exclusively present in olives and olive

products with a potency that is attributed to the synergistic effect of a catechol structure

to stabilize radicals and a short aliphatic chain that gives it the correct lipophilicity to

partition into the membrane (Visioli et al., 2002). By-product valorization is particularly

GRJNST, Volume: 04 - Issue 2 (2026) / ISSN P: 2790-7643

Page 5

appealing to olive mill wastewater, which currently presents a challenge to the environment

as a disposal issue due to its high levels of hydroxytyrosol (up to 5 g/L) (Obied et al.,

2005).

2.2 Dietary Fibers

Carbohydrate polymers of degree of polymerization 3 or above that are not hydrolyzed

by endogenous human digestive enzymes are called dietary fibers (Table 1). Fibers are

used in meat matrices in various technological applications, such as water-holding capacity

(5-20 times dry weight), texture-modifying, emulsion-stabilizing, and physical entrapment

of lipid droplets (Mehta et al., 2015). The by-products of fruits and vegetables such as

apple pomace, citrus peels, grape pomace supply fiber concentrates with 40-70% dietary

fiber and related polyphenols (Ajila et al., 2012).

2.3 Plant Proteins Soy protein

is the most common plant protein that is used in meat-related products, with the option

of soy flour (50% protein), soy protein concentrate (70%), and soy protein isolate (90%).

The properties of the functional properties are based on 7S and glycinin fraction (11S)

with larger 11S/7S ratios giving stiffer gels which are desirable in emulsified meat product

(Nishinari et al., 2014). Pea protein has also become a solution to the issue of soy

allergens, but it has a lower solubility and emulsifying property (Lam et al., 2018).

2.4 Glucosinolates and Isothiocyanates Myrosinase

helps to break down the tissues of plants of the Brassicaceae, producing isothiocyanates,

which are sulphur-containing compounds. Broccoli Sulforaphane has a strong

antimicrobial effect against the bacteria Listeria monocytogenes and Escherichia coli

O157:H7 by reacting with thiol groups on key microbial enzymes (Dinkova-Kostova and

Kostov, 2012). The use is sensitive to the management of myrosinase activity, which is

usually neutralized by thermal treatment.

3. Mechanisms of Action in Meat Matrices

3.1 Antioxidant Mechanisms

The major degradative process that reduces the shelf life of meat products is lipid

oxidation. Plant bioactives act in a number of complementary ways (Table 2).

Abbreviation: BDE, bond dissociation enthalpy

3.1.1 Radical Scavenging

The phenolic compounds stop radical chain reactions by donating hydrogen atoms to

peroxyl radicals (LOO) to produce relatively stable phenoxyl radicals that are not effective

oxidation propagators. The standard bond dissociation energy (BDE) of the O-H group

of phenols at room temperature is 315-380 kJ/mol, which is significantly lower than the

380-420 kJ/mol needed to abstract methylene hydrogen of polyunsaturated fatty acids

(Wright et al., 2001). Additional resonance stabilization is the presence of ortho-

dihydroxy (catechol) structures which are intramolecularly hydrogen bonded.

3.1.2 Metal Chelation Lipid oxidation

is catalyzed by transition metal ions (iron, copper) with the transformation of lipid

hydroperoxides to reactive alkoxyl (LO•) and peroxyl radicals. Phenolic compounds

chelate metal ions with both hydroxyl and carbonyl groups; catechol structure produces

five-membered chelate rings especially when the metal ions are chelated (Khokhar and

Apenten, 2003). Nevertheless, the heme iron, which is the most common form in meat,

is still mostly insoluble in aqueous-phase chelators, but some flavonoids (quercetin,

myricetin) also react directly with heme iron, impairing its peroxidase activity.

3.2 Antimicrobial Mechanisms

3.2.1 Membrane Disruption

Phenolic substances and essential oil constituents are absorbed into bacterial membranes

and alter fluidity and integrity in them. The single membrane is enclosed by a relatively

porous peptidoglycan and therefore Gram-positive bacteria are more prone as compared

to Gram-negative bacteria whose outer membrane lipopolysaccharide limits the diffusion

of hydrophobic compounds (Burt, 2004). Thymol and carvacrol intercalate into the acyl

chain region of the membrane, interfering with the gel to liquid crystalline change over.

Enzyme Inhibition and Quorum Sensing is the third category of stimulants.

Isothiocyanates have a covalent reaction with thiol groups, which inhibits a wide variety

of microbial enzymes such as enzymes of energy metabolism and stress response (Fahey

et al., 2001). Flavonoids prevent DNA gyrase and dihydrofolate reductase. Quercetin and

naringenin, at sub-inhibitory concentrations, disrupt quorum sensing through competitive

binding to autoinducer receptors and do not exert a selective pressure to change virulence

(Vikram et al., 2010).

3.3 Color Stabilization

Meat color is stabilized by plant bioactives by: (1) inhibiting oxidation of myoglobin by

retarding the accumulation of oxidizing species, (2) inhibiting oxidation of myoglobin

directly by reducing metmyoglobin to ferrous myoglobin by electron transfer and (3)

chelating copper which mediates coupled lipid-myoglobin oxidation Nevertheless, at high

concentrations, protein digestibility can be decreased by the protein-binding

characteristics of tannins (Bravo, 1998) and some phenolics can be pro-oxidant at high

concentrations or in the presence of transition metals (Cao et al., 1997).

4. Enrichment Strategies

The fourth method is known as Endogenous Enrichment (Animal Feeding). Endogenous

enrichment is used to deposit bioactives in muscle tissue by changing the diet of animals.

It is a method whereby the compounds are dispersed throughout the matrix at the cellular

level and could minimize the thermal degradation during processing. Transfer efficiency,

however, is usually low with polyphenols, which are highly metabolized and conjugated

in the gastrointestinal tract and liver (Manach et al., 2004). Enrichment with vitamin E (

200-500 mg/kg feed): dietary supplementation of vitamin E ( 200-500 mg/kg feed) has

been shown to increase muscle 200-500 mg/kg feed) has been shown to increase muscle

200-500 mg/kg feed) has been shown to increase muscle 200-500 mg The

supplementation of selenium using selenized yeast raises muscle selenium levels and

selenoprotein functions. The enrichment with polyphenols has had varied effects; whereas

in some cases, grape pomace and olive leaf supplementation have increased the content of

polyphenols in muscles, the effect size is typically small in comparison with direct addition

(Luciano et al., 2009).

The enrichment process can also be exogenous (Direct Incorporation). With direct

incorporation, there is increased control over end concentrations, as well as access to a

broader spectrum of compounds (Table 3). Powder addition of dried plant materials

(spices, fruit powders) does not need any special equipment but is challenging to sensory.

Extract incorporation enables the delivery of standardized bioactives with less sensory

effects; extracts made using water, ethanol, or ethanol-water have varying compositional

profiles (Shahidi and Ambigaipalan, 2015).

Encapsulation technologies address limitations of direct incorporation. Spray drying in

maltodextrin or gum arabic is commercially mature but exposes bioactives to thermal

stress. Liposomal encapsulation protects heat-sensitive compounds but costs remain high

for premium applications only (Fang & Bhandari, 2010).

5. Impact on Meat Product Quality and Safety

5.1 Physicochemical Properties

The incorporation of plant bioactives affects pH by organic acids in extracts (decreasing

pH) or buffering of plant proteins. Dietary fibers are effective in significantly increasing

water-holding capacity: insoluble fibers retain water in capillary pores, whereas soluble

fibers create hydrated gels. The two mechanisms enhance cooking yield and minimize

purge loss (Petersson et al., 2014). Phenolic compounds bind each other to the

myofibrillar proteins, and that may enhance gel strength and hardness. But over

crosslinking gives unwanted firmness. Incorporation of fiber tends to enhance hardness of

the product and decrease its cohesiveness, as well as depending on the size of particles in

the fiber (Talukder, 2015).

5.2 Oxidative Stability

In many studies, there is a lower level of thiobarbituric acid reactive substances (TBARS),

lower peroxide values, and lower levels of hexanal in the plant enriched products (Table

4). Protection is influenced by lipophilicity (more effective in high-fat foods), processing

(cooked vs. raw) and bioactive concentration.

Comparative studies show some plant extracts achieve protection equivalent to

BHA/BHT at comparable concentrations (rosemary, oregano, olive), while others require

higher concentrations. The higher cost of plant extracts remains a barrier for price-

sensitive market segments.

5.3 Microbial Quality

The antimicrobial effect in meat matrices is usually less impressive than the antioxidant

effect because of the effects of phenolic compounds binding to proteins and lipids, which

limits the access of microbes to them (Weiss et al., 2010). Oregano and thyme extract

lower total viable counts 1- 2 log CFU/g and shelf life up to 2-5 days. Isothiocyanate

extracts are active against L. monocytogenes but efficacy is often similar to that of nitrite

and concentrations of the extract are usually required to cause unwanted sensory properties

(Tajkarimi et al., 2010).

5.4 Sensory Properties

Extracts high in polyphenols add bitterness and astringency, the latter being a response

to salivary proteins (Drewnowski and Gomez-Carneros, 2000). Spice and herb extract

also add typical flavors, such as rosemary, oregano, and thyme add Mediterranean flavours

that can be used with most meat products and fruit extracts can add sweet or sour flavours

that are less appropriate in savoury dishes. Functional benefit Consumer studies show

moderate levels of enrichment (0.1-0.5% extract) can be functional without generating

any sensory difference. The increased concentrations offer more technical advantages, but

tend to generate noticeable variations that diminish consumer acceptance (Hwang and

Lee, 2017).

6. By-Product Valorization and Sustainability.

Agricultural wastes can be used as bioactive sources because they use agri-food by-

products, which meets both economic and environmental goals (Table 5). Hydroxytyrosol

is found in olive mill wastewater and pomace in concentrations that are economical to

extract and reduces an environmental disposal issue (Roig et al., 2006).

Green extraction methods have less environmental impact: solvent-free extracts can be

formed by using supercritical CO 2 extraction, but high-pressure equipment is required,

whereas pressurized liquid extraction and ultrasound-assisted extraction are intermediate

methods with less solvent usage (Chemat et al., 2017). Life cycle analysis shows that the

overall environmental impact can be decreased by a factor of 30-50 in the case of by-

product valorization versus virgin production of bioactive (Galanakis, 2012).

7. Challenges and Future Directions

7.1 Current Challenges

The first challenge is its sensory compatibility. To attain technical functionality at

concentration levels that are lower than sensory detection limits it is necessary to think

deeply about the bioactive sources, encapsulation technologies and product-specific

GRJNST, Volume: 04 - Issue 2 (2026) / ISSN P: 2790-7643

optimization (Brewer, 2011).

Retention of bioavailability and bioactivity during processing and storage limits efficacy.

Heat treatment (cooking, pasteurization) destroys heat sensitive compounds, and storage

losses are further caused by light and oxygen exposure. To some extent, these issues are

resolved with the help of encapsulation and regard to careful processing conditions

(Davidov-Pardo et al., 2015). Depending on jurisdiction, regulatory approval of novel

plant extracts is different. The EU needs new food approval of extracts with no history

of significant consumption whereas the US GRAS (Generally Recognized as Safe)

decision needs a substantial amount of safety evidence (Nabors, 2005). Cost

competitiveness Cost competitiveness with the synthetic preservatives is still a challenge.

Although by-product valorization saves on costs, the process of purifying the product to

the food-grade level is costly. The gap is still being reduced by economies of scale and

better technologies in extraction.

7.2 Future Research

Directions targeted production of bioactives through precision fermentation provides

high-purity and uniform bioactives regardless of seasonal or geographical fluctuations.

Compounds such as resveratrol, vanillin, and other phenolics have already been

successfully produced using yeast and bacterial platforms (Paddon and Keasling, 2014).

In parallel, nanoencapsulation technologies—including solid lipid nanoparticles,

nanostructured lipid carriers, and cyclodextrin complexes—have demonstrated strong

potential to enhance the solubility, stability, and controlled release of bioactives within

meat matrices (Ezhilarasi et al., 2013). However, challenges related to large-scale

production and regulatory approval still need to be addressed. Furthermore, optimization

of the meat–bioactive interface through approaches such as multilayered product

structures, emulsion-based delivery systems for lipophilic compounds, and co-

crystallization techniques to mask undesirable flavors represents a critical area of

advancement (McClements, 2015). In the long term, the development of customized

functional meat products tailored to specific health needs—such as cardiovascular

protection, glycemic control, and anti-inflammatory effects—will require improved

strategies for bioactive stabilization and cost-effective production.

In this context, the collective body of recent research provides strong foundational support

for these future directions by demonstrating how functional ingredients and advanced

food systems can be effectively designed and applied. For instance, the incorporation of

probiotic cultures such as Lactobacillus rhamnosus into food systems illustrates the

feasibility of microbial-assisted bioactive enrichment (Ahmed et al., 2024), which aligns

closely with precision fermentation strategies. Similarly, the development of hybrid

protein systems, including soy–whey and whey–corn formulations, highlights the

potential for structurally optimized matrices capable of carrying and stabilizing bioactive

compounds (Butt et al., 2025a; Butt et al., 2025b). Evidence from nutritional and clinical

studies further supports the functional relevance of such bioactives, as phytochemical-rich

diets and zinc supplementation have been shown to regulate metabolic pathways, influence

IGF-1 expression, and modulate epigenetic markers like DNA methylation associated

with obesity and insulin resistance (Butt et al., 2026a; Butt et al., 2026b).

Moreover, comparative evaluations of conventional and alternative meat products

demonstrate that physicochemical, microbial, and sensory properties can be optimized

without compromising safety or consumer acceptability (Butt et al., 2024; Butt et al.,

2025c), which is essential for successful bioactive integration into meat systems.

Supporting this, studies on functional dietary components—such as olive and flaxseed

oils in mitigating hepatotoxicity (Khan et al., 2024) and probiotic yogurt in improving

metabolic health and weight management (Rashid et al., 2026)—reinforce the therapeutic

potential of bioactive-enriched foods. These findings directly complement technological

strategies such as emulsion systems and multilayered delivery approaches proposed for

meat-bioactive interfaces. Additionally, insights from human physiology and

biomechanics research (Mahmood et al., 2026) extend the application of functional foods

toward performance and recovery, while research on artificial intelligence and

sustainability emphasizes the importance of integrating technological innovation and

socio-environmental considerations into future food system development (Kamal & Butt,

2026; Khurshid et al., 2026).

Overall, the integration of these studies with emerging technological advancements

underscores a clear transition toward next-generation functional meat products, where

precision fermentation, nanoencapsulation, and optimized delivery systems are combined

with evidence-based nutritional strategies. This convergence not only addresses current

limitations in stability, scalability, and consumer acceptance but also paves the way for

personalized, health-oriented, and sustainable food solutions (Ahmed et al., 2024; Khan

et al., 2024; Butt et al., 2024; Butt et al., 2025a; Butt et al., 2025b; Butt et al., 2025c; Butt

et al., 2026a; Butt et al., 2026b; Rashid et al., 2026; Mahmood et al., 2026; Kamal &

Butt, 2026; Khurshid et al., 2026; Paddon and Keasling, 2014; Ezhilarasi et al., 2013;

8. Conclusion

Plant-based bioactive compounds provide a feasible approach toward designing

functional meat products that meet the concerns of the population about their health and

the desire of the consumer to use clean-label ingredients. The key classes, such as

polyphenols, dietary fibers, plant proteins, and glycosylates, have multifunctional

antioxidant, antimicrobial, and health-promoting properties due to their well-

characterized multimodal mechanisms that comprise radical scavenging, metal chelation,

membrane disruption, and enzyme inhibition. Animal feeding is a method of endogenous

enrichment, which can spread bioactives evenly but with low transfer efficiency of most

polyphenols. Direct addition of powders, extracts or encapsulated preparations allows

exogenous enrichment with more accurate control of the final concentrations and a

broadened range of compounds such as agri-food by-products. Valorization of olive mill

wastewater, grape pomace, pomegranate peel and other by-products fits into the concept

of the circular economy and minimizes expenditures. The incorporation of plant bio

actives usually enhances oxidative stability and in many cases is as protective as the

synthetic antioxidants. Smaller in effect, antimicrobial effects are able to increase shelf life

by 2-5 days with the proper extracts. Moderate levels of enrichment (0.1-0.5% extract)

have functional advantages but are not perceivable in sensory properties in many products.

There are still critical issues to overcome higher concentration sensory compatibility,

bioactive degradation in processing and storage, regulatory acceptance of novel extracts,

and competitive cost with synthetic preservatives. Future research needs are precision

fermentation to achieve consistency, high purity; nanoencapsulation to achieve increased

stability and finer release; hybrid product approaches to the optimum meat-bioactive

interface; and life cycle analysis to quantify environmental benefit. The production of

functional meat products that have been fortified with plant bioactives is a noteworthy

way in which the meat industry can address the changing consumer needs, societal health

advice and sustainability demands. Interdisciplinary cooperation between food scientists,

nutritionists, sensory specialists, and process engineers is needed to maximize these

complicated matrices to achieve success.
