: Being an important source of human enteric diseases, microbiological safety is one of the major risk concerns in the meat industry. In order to inhibit and inactivate microbial contamination and extend the shelf life of meat products, different procedures have been practiced, including the addition of bacteriocins as proteinaceous antagonistic preservatives. This article discusses the application of bacteriocins which are capable of controlling the growth of pathogenic and spoilage microorganisms in meat and meat products. We identify possible ways to improve the performance of bacteriocins ensuring food safety and toxicity. We first provide a brief introduction to the classification of bacteriocins and then discuss their antimicrobial properties and mechanism of action alone and in combination with other hurdles in meat and meat products. Moreover, application methods of bacteriocins in meat products are described and cross-compared, introducing emerging meat products containing bacteriocins. : Despite the existence of many reports related to the application of bacteriocin-producing strains of lactic acid bacteria in meat products, very few review articles have attempted at evaluating the application of bacteriocins in the red meat while observing their antimicrobial mechanism of action as well as evaluating their applications in meat products. The application of these proteins in meat products has received considerable attention; however, there are still some drawbacks and limitations for their application. Characterization, identification, toxicity evaluation and investigating application level of bacteriocins produced by meat borne/non-meat borne bacteria appears to be necessary in order to increase the efficiency of extending shelf life and improving the microbial stability of meat products.

PurposeThe objective of the study was to assess consumer exposure to warmed-over flavour, their eating habits with respect to pre-cooked stored meats, awareness of antioxidants and attitudes towards the use of natural antioxidants as preservatives in meat and meat products.Design/methodology/approachA total of 238 Check-All-That-Apply (CATA) design questionnaires were used to gather information from the University of Fort Hare community in the Eastern Cape province of South Africa.FindingsThe majority of the respondents had been exposed to warmed-over flavour before. More than half of the respondents did not know about antioxidants. Respondents were in support of the use of natural antioxidants in meat and meat products.Research limitations/implicationsThe study mainly captured consumer habits based on living arrangements. Age influence could not be extrapolated due to the nature of the population, which was being studied. The population was limited to the University community, which is mainly made up of not so widely spread age groups and more or less similar levels of education. As a result, the findings and conclusions may not be a true reflection of the general public consumers in terms of age, level of education and employment status.Originality/valueThis research presents an original insight into consumer habits concerning the purchasing and storage of pre-cooked meat and meat products. The study revealed that most consumers nowadays prefer ready-to-eat or pre-cooked meat and meat products due to convenience. The warmed-over flavour is common in pre-cooked meats. The findings suggests that the meat industry has to improve the shelf-life of pre-cooked foods such that warmed-over flavour development is delayed to fit into the current consumer habits. In recent years there has been a growing interest in the use of natural antioxidants to improve shelf-life of muscle foods. However, there is a dearth of information on consumer attitudes towards the use of natural antioxidants as preservatives. This study reveals that consumers are willing to try products formulated using natural antioxidants.

Microbial food contamination is a major concern for consumers and food industries. Consumers desire nutritious, safe and “clean label” products, free of synthetic preservatives and food industries and food scientists try to meet their demands by finding natural effective alternatives for food preservation. One of the alternatives to synthetic preservatives is the use of natural anti-microbial agents in the food products and/or in the packaging materials. Meat and processed meat products are characteristic examples of products that are highly perishable; hence natural anti-microbials can be used for extending their shelf-life and enhancing their safety. Despite several examples of the successful application of natural anti-microbial agents in meat products reported in research studies, their commercial use remains limited. This review objective is to present an extensive overview of recent research in the field of natural anti-microbials, covering essential oils, plant extracts, flavonoids, animal-derived compounds, organic acids, bacteriocins and nanoparticles. The anti-microbial mode of action of the agents, in situ studies involving meat products, regulations and, limitations for usage and future perspectives are described. The review concludes that naturally derived anti-microbials can potentially support the meat industry to provide “clean label”, nutritious and safe meat products for consumers.

Introduction. Some ingredients of plant origin possess both antioxidant and bacteriostatic properties. If used in the food industry, they can inhibit microbiological and oxidative damage, thus increasing the shelf life of meat products. Oregano extract is one of such substances, which means that it can be used as an antioxidant and preservative. Therefore, the study of this plant has a significant theoretical and practical potential for the food industry. Study objects and methods. The present research featured ground trimmed beef. The samples with 20% of fat tissue were used to determine the microbiological parameters, while the samples with 30% of fat were used to obtain data on oxidative stability. The control sample contained no additional ingredients. The sample with food additives was pre-treated with acidity regulators and antioxidants, namely sodium acetate E262, ascorbic acid E300, sodium ascorbate E301, sodium citrate E331, and rosemary extract E392. The sample with oregano extract was pre-treated with oregano extract (Origani vulgaris herba L.) in the ratio of 5 g of extract per 1 kg of meat. The extract had been dissolved in 100 g of water. The samples were stored at 4 ± 2°C for 12 days. A CM5 spectrophotometer (Konica Minolta, Japan) was used to determine the color characteristics. The induction period of oxidative stability was determined using an Oxitest oxidative stability analyzer (Velp Scientifica, Italy). The studies were conducted in Austria, Linz. Results and discussion. Oregano extract stabilized the redness rating. For the sample with oregano extract, the induction period of oxidative stability was twice as long as for the control sample and the sample with antioxidants. In addition, oregano inhibited the growth of aerobic and anaerobic microorganisms. Conclusion. The antioxidant and antimicrobial properties of oregano extract prolong the shelf life of ground beef, which makes it possible to reduce the amount of food additives.

Organoleptic Characteristics

During the last few years, consumers’ demand for animal protein and healthier meat products has increased considerably. This has motivated researchers of the meat industry to create products that present healthier components while maintaining their safety, sensory characteristics, and shelf life. Concerning this, natural plant extracts have gained prominence because they can act as antioxidants and antimicrobials, increasing the stability and shelf life of processed meat products. It has been observed that the leaves of plant species (Moringa oleifera, Bidens pilosa, Eugenia uniflora, Olea europea, Prunus cerasus, Ribes nigrum, etc.) have a higher concentration and variety of polyphenols than other parts of the plants, such as fruits and stems. In Chile, there are two native berries, maqui (Aristotelia chilensis) and murtilla (Ugni molinae Turcz), that that stand out for their high concentrations of polyphenols. Recently, their polyphenols have been characterized, demonstrating their potential antioxidant and antimicrobial action and their bioactive action at cellular level. However, to date, there is little information on their use in the elaboration of meat products. Therefore, the objective of this review is to compile the most current data on the use of polyphenols from leaves of native plants in the elaboration of meat products and their effect on the oxidation, stability, and organoleptic characteristics during the shelf life of these products.

Antimicrobial Effects

Phosphates are widely used as food additives in meat products to increase the water-holding capacity, reduce the cooking loss and improve the textural properties. Furthermore, phosphates protect aroma and accelerate the formation of cured meat color as well as having antioxidant and antimicrobial effects. Many research about using phosphates in meat products showed that increasing chain length of phosphates improves antioxidant and antimicrobial effects. It has been stated that vacuum or modified atmosphere packaging, the use of phosphates with natural antioxidants and encapsulation of phosphates are useful approaches to enhance the antioxidant effects of phosphates. It has been reported that irradiation, vacuum or modified atmosphere packaging, storage at low temperature and the use of the salt provide strong synergistic effect on the antimicrobial properties of phosphates. In this review, researches about antioxidant and antimicrobial properties of phosphates and suggestions for the meat industry about industrial applications of phosphates are presented.

And Storage

Many microbiological, enzymatic, physicochemical, and biochemical changes occur during the production and storage of fresh and processed meat products, which tend to deteriorate more easily by their nature. Nevertheless, consumers mainly prefer cost-effective foods that have a longer shelf life and minimally modified natural properties, can be easily prepared, and in which fewer additives are used. For these reasons, the food packaging industry has turned towards developing new applications with different functions that are not found in traditional packaging methods, such as antimicrobial packaging systems, especially for the protection and improvement of food quality and safety. In this type of packaging, in addition to improving food safety and quality, the shelf life of the product is extended by slowing down the growth rate of microorganisms. Thus, the existing growth of microorganisms during the transportation and storage of the product is also prevented. Therefore, the preservatives taken into the human body with foods are reduced, and the negative effects on health are also avoided. In these systems, the application of antimicrobial food packaging components to the packaging material can be performed by the addition of antimicrobial agents into the polymer, coating polymer surfaces with antimicrobial agents, immobilizing antimicrobial agents on the polymer, and using polymers with antimicrobial properties. In this review, antimicrobial packaging and application methods were generally explained, and innovative packaging systems and their use in meat and meat products were evaluated.

Meat Type

Meat industries are constantly facing new waves of changes in the consumer’s nutritional trends, food safety, and quality requirements and legislations leading to an increase in interest for meat biopreservation to respond to all of these modern socioeconomic demands. Hence, to replace synthetic and/or expensive additives, new technologies in preserving meat products from microbial contamination have been established. In this context, organic acids and their salts have been considered as the most popular examples of preservatives that offer several advantages to be applied in meat industry. Here, characteristics of organic acids/salts commonly used in meat preservation were described based on the published literature. Moreover, after outlining the challenges and advantages of their use in meat industry, their current applications as meat preservatives on various meat type matrices such as beef, pork, sheep, and poultry were quite exposed based on previous and recent research works. Then, different application types were highlighted. Besides, some potent synergistic approaches based on several combinations of organic acids/salts with different existing preservative techniques are reported with an emphasised discussion of their application as possible solution tools to mainly overcome some problems linked to organic acids/salts when used solely, thus contributing to ensure the overall safety and improve the quality of meats. Finally, despite their usefulness in meat preservation, organic acids/salts may possess detrimental traits. In this context, a detailed discussion on their limits of use in meat products was provided in the last section of this paper.

Edible film and coatings are been looked upon for preservation of fruits, vegetables and bakery products. Extended shelf life with preservation of natural properties of food is always been a challenge; by incorporation of bio-actives in edible coatings, the shelf life can be increased as they are known for their antioxidant and antimicrobial properties. With this view, present study was undertaken, where edible coatings were prepared from starch, gelatin and glycerol and incorporated with Lemon peel extracts and coated on apples for increased shelf life. Antimicrobial activity of Lemon peel extracts was studied on eight organisms by broth dilution method and were found to be effective at concentration 3mg/mL-9mg/mL for bacteria and 50mg/mL- 90mg/mL for fungi. Fuji apples coated with starch-gelatin based edible formulation containing lemon peel extracts were studied for the effect of coating on fruit shelf life during storage for 28 days. Incorporation of lemon peel extract into edible coating improved shelf life with reducing rate of browning of apples.

Current trends in meat and meat products exports are considered. The dynamics and structural changes in meat exports by types and degree of processing (beef and veal, pork, poultry, finished meat products) are analyzed. The paper proves that in recent years, only meat and edible poultry by-products have taken a competitive position in the world market. Accordingly, the dynamics of exports of this type of meat is positive, and the share of these products in the structure of exported meat is the largest (86.09%). Possible threats to the growth of import dependence on certain types of meat products, in particular, chilled and frozen beef and veal, pork, are indicated. The rating of the largest countries-importers of meat and meat products (by types) from Ukraine is built, their share in the structure of meat exports is determined. Changes in the geographical structure of exports have been studied, which indicate a low level of diversification of the geography of exports of certain types of meat (pork, beef). At the same time, a positive development of the geographical structure of poultry meat exports (exported to more than 100 countries) was revealed. Problems of the export potential development in the meat industry of Ukraine are revealed. In particular, the problems of livestock development (outdated technologies and production techniques that reduce the efficiency and productivity; inefficiency of the organization of purchase and processing of meat, which leads to reduced breeding in small businesses and households; inefficiency of state incentives, etc.) and industrial meat production (lack of raw materials, obsolescence of fixed assets and production technologies, poorly developed logistics, etc.). The solution of these problems requires: a systematic approach, which will encourage the cooperation of agricultural and industrial production, cooperation with importers of meat products and protection of domestic producers in the domestic and international markets, creating a favorable investment and information environment that will promote the meat industry development.
