Meat is an essential source of nutrients in the human diet and a component of global food security. In the context of a growing demand for functional and healthy foods, the addition of non-meat ingredients, such as dietary fibres, is a promising strategy for improving the quality of meat products. This review aimed to identify and synthesise the available recent literature regarding the impact of fibre-rich ingredients on the properties of meat products, investigating how various plant sources (such as cereals, vegetables, legumes, and fruits) can be used in various forms of meat products, such as meat pastes, emulsified products, and minced and restructured meat products. Analyses of technological parameters revealed improvements in water-holding capacity, cooking losses, and an increased production yield. The addition of fibre has demonstrated a favourable effect on low-fat products, stabilising the emulsion and improving its physical texture properties. The chemical analysis highlighted an increase in dietary fibre and mineral content, as well as a decrease in fat content depending on the type and level of fibre added. Sensory changes included aspects related to the colour, aroma, texture, and overall acceptability of the products. The optimisation of the type and level of fibre is essential to obtain meat products with improved characteristics.

Game meat contains bioactive compounds that directly influence the formation of a rich reservoir of flavor precursors that produce specific sensory properties. Quality is considered one of the most influential determinants of consumer behavior, but the interpretation of this concept differs between consumers. Although recognized for its quality, its unique sensory characteristics (smell, taste, aroma) may have a major impact on consumer perception. The aim of this review is to describe the consumer behavior regarding game meat through elements of neuroperception, using methods of analysis, observation, and interpretation of scientific information from the literature. Following the analysis of published papers on this topic, it was shown that external factors influencing the biological basis of behavior could provide explanations for the acceptance or rejection of this type of meat and solutions. Neuroperception can explain the mechanism behind consumer decision-making. The influence of extrinsic factors (environment, mood, emotions, stress) shapes the perception of the quality attributes of game meat, the unique sensory characteristics of game meat passing through a primary filter of sensory receptors (eyes, nose, tongue, etc). Game meat is darker and tougher (compared to meat from domestic animals), and the taste and smell have the power to trigger memories and change the mood, influencing consumer behavior. Understanding consumer attitudes towards game meat in relation to quality attributes and the physiology of sensory perception can provide important insights for food industry professionals, processors, sensory evaluators, and researchers.

The global trend toward sustainable and health-promoting foods has encouraged the reformulation of meat products that strategically incorporate high-quality animal proteins and functional compounds derived from plants. This study focuses on a complex food concept: meat-based pasta formulated from pork, semolina, and dietary fibers (apple and sugar beet). The quality attributes and the effects of different formulations were evaluated in comparison with a control sample. The findings show that the addition of dietary fibers significantly impacted the chemical composition, lowered the pH and increased water activity. The incorporation of the apple and sugar beet fibers increased the total dietary fiber content from 2.94% (control) to 9.59% and 11.15%, respectively, at the highest level of inclusion. Moreover, texture profile analysis of the raw samples revealed an enhancement in hardness (from 8.01 N in the control to maximum values of 21.23 N and 26.37 N), gumminess (from 3.28 N to 10.43 N and 12.36 N), and slight improvements in cohesiveness (from 0.41 to maximum values of 0.49 and 0.51) with the addition of apple and sugar beet fibers, respectively. The color parameters (L*, a*, b*) varied depending on the fiber source, with beet fiber imparting higher lightness and redness, while apple fiber contributed to darker tones. An initial consumer acceptability test revealed a positive perception of the innovative product, particularly for formulations with low and medium percentages of fiber addition. Overall, the results demonstrate that meat-based pasta can be successfully formulated with dietary fibers, providing an innovative and feasible alternative that meets current consumer expectations for novel, healthy, and sustainable foods.

Improving tenderness in whole-muscle pork products remains a technological challenge, particularly when natural processing strategies are preferred over conventional additives, as texture is regarded as one of the most important quality attributes influencing consumer perception and acceptance of meat products. This study investigated whether two plant proteases, papain and bromelain, incorporated into a red algae-based brine containing Palmaria palmata could enhance the quality of injected pork loin without compromising microbiological safety or sensory acceptance. Seven batches were produced: a control sample and six enzyme-treated samples containing papain or bromelain at 0.015%, 0.030%, and 0.045%. Overall, the enzymatic treatments had a limited effect on proximate composition. However, a modest decrease in fat content was observed, from 3.09% in the control sample to 2.70–2.82% in the samples treated with the highest concentrations of papain and bromelain (0.045%). In contrast, instrumental color and texture were strongly affected. Enzyme-treated samples became lighter, less red, and less saturated, with redness decreasing from 13.07 in the control to 5.19–6.66 in the highest-dose treatments and total color differences reaching 8.66. The most relevant effect was observed in texture, where papain and bromelain markedly reduced shear force, shear work, hardness, gumminess, and chewiness; shear force decreased from 26.22 N/cm² in the control to 10.78 N/cm² and 9.38 N/cm² in the batches treated with the highest enzyme concentrations. During refrigerated storage, total viable counts increased gradually but remained low, with a maximum of 4.56 × 10² CFU/g, while Escherichia coli, Salmonella spp., and Listeria monocytogenes were not detected. Sensory analysis further showed that enzymatic treatment improved perceived tenderness and juiciness without reducing overall acceptability. These findings indicate that papain and bromelain can be used as natural tenderizing tools in injected pork loin, offering a promising route toward cleaner-label meat products with improved texture and preserved microbiological quality.

The incorporation of plant-based protein ingredients into processed meat products represents a promising strategy for reformulating meat products while addressing sustainability and resource efficiency concerns within the food industry. This study investigated the effect of sweet lupin flour incorporated at 2%, 4%, and 6% substitution levels on the quality characteristics of chicken meat sausages. Four batches were produced: a control (CB0%) and three lupin-enriched formulations (CLS2%, CLS4%, CLS6%), and evaluated for proximate composition, pH, water activity, colorimetric parameters, Warner–Bratzler shear force, and sensory acceptability. Lupin flour incorporation significantly modified all parameters, increasing ash, fat, carbohydrate, and energy content while moderately reducing moisture and protein. A progressive decrease in pH and water activity was observed alongside a colorimetric shift toward higher lightness and yellowness, with total color differences exceeding the visual perceptibility threshold of 5 at CLS4% and CLS6%. Shear force and work of cutting increased proportionally with substitution level, reflecting structural reinforcement of the protein matrix. Sensory evaluation confirmed that 2% substitution maintained overall acceptability within the positive range of the hedonic scale, while 4% remained acceptable but with some sensory decline, and the 6% received scores below the scale midpoint. These results suggest that lupin flour can be incorporated at up to 4%, while maintaining overall sensory scores within the positive range of the hedonic scale, supporting its potential as a plant-derived ingredient in the reformulation of poultry-based processed meat products.
