Traditional meat preservation techniques such as smoking, drying, and salting have various shortcomings and limitations in effectively reducing microbial loads and maintaining meat quality. Consequently, chemical compounds have gained attention as promising alternatives for decontamination, offering the potential to extend shelf life and minimize physical, chemical, and sensory changes in meat. Chlorine-based compounds, trisodium phosphate, organic acids, bacteriocins, lactoferrin, and peracetic acid are technologies of recent industrial applications that inhibit spoilage and pathogenic microorganisms in meat. This review explores the critical aspects of decontamination and assesses the efficacy of different chemical compounds employed in meat preservation. These compounds exhibit strong microorganism inactivation capabilities, ensuring minimal alterations to the meat matrix and substantially reducing environmental impact.

Cell-based meat (CBM) technology is a highly promising alternative to traditional animal agriculture, with considerable advantages in terms of sustainability, animal welfare, and food security. Nonetheless, CBM's successful commercialization is dependent on efficiently dealing with several critical concerns, including ensuring biological, chemical, and nutritional safety as well as navigating the global regulatory framework. To ensure CBM's biological safety, detecting and mitigating any potential hazards introduced during the manufacturing process is crucial. Concerns include microbial contamination, the utilization of animal-derived growth media, and the risk of viral or prion infection. Similarly, chemical hazards include residues from growth media, scaffolding materials, and other bioprocessing agents. For consumer acceptance, CBM's nutritional qualities should be comparable to those of conventional meat, indicating adequate protein content, essential amino acids, vitamins, and minerals. Additionally, CBM's safety in terms of allergenicity and the presence of anti-nutritional factors must be rigorously assessed. Advances in cell culture techniques and biomanufacturing methods are requisite to achieving high-quality CBM with desirable nutritional attributes. The regulatory framework for CBM is actively expanding, with significant regional variations. Singapore is currently the only country that has received approval for the market placement of CBM, although the United States has developed a regulatory structure involving the United States Department of Agriculture and Food and Drug Administration. As CBM holds great potential as a sustainable and ethical alternative to conventional meat, addressing challenges related to biological and chemical safety, nutritional quality, and regulatory approval is essential for its successful market integration.

Simulating meat flavor via Maillard reaction model systems that contain a mixture of amino acids and reducing sugars is an effective approach to understanding the reaction mechanism of the flavor precursors. Notably, animal resources such as fish, beef, chicken, pork hydrolysates, and fats are excellent precursors in promoting favorable meaty and roasted flavors and umami tastes of Maillard reaction products. The experimental conditions and related factors of the model systems for sensory enhancements, debittering, and off-flavor reduction with meat and by-products are summarized in this review. The review also highlights the flavor precursors in the animal resources and their participation in the Maillard reaction. This review provides a basis for a better understanding of the model systems, especially those prepared with animal resources.

Production of alternative proteins is crucial for the development of future protein resources. This study explored the creation of sustainable animal resources by combining extrusion molding and three-dimensional (3D) printing technologies. Extrusion effectively organizes vegetable proteins at high temperatures and pressures to replicate meat-like textures, and high-moisture extrusion successfully mimics the fiber structure of conventional meat. However, many meat analogs products still differ from conventional meat in terms of sensory properties such as texture, juiciness, and flavor, indicating the need for quality improvement. Researchers have leveraged 3D printing technology to incorporate fat analogs and enhance the appearance and texture through muscle fiber simulation. This technology allows for precise arrangement of muscle fibers, formation of adipose tissue, and marbling, thereby improving the overall sensory experience. By combining extrusion and 3D printing, we can enhance the nutritional and organoleptic qualities of meat analogs, ultimately meeting consumer expectations and achieving a balance between plant- and animal-based materials.

Flavor and taste are critical factors influencing consumer attraction for meat, shaping preferences and commercial demand. This review examines conventional and novel approaches to flavor and taste creation in the meat business, highlighting ways that improve sensory profiles and meet consumer demands. Conventional methods, such as aging and marination, are analyzed in conjunction with new technologies, including enzymatic treatment, fermentation, genetic treatments to alter texture and enhance umami. This study also emphasizes innovative methods to improve flavor of plant-based meat products, designed to meet the increasing demand for healthier, sustainable, and customizable meat products. The paper examines various methodologies and trends, offering a thorough grasp of flavor creation in the meat sector and highlighting the potential of creative approaches to transform meat flavor and taste profiles in response to evolving consumer and industry demands.

Amphibians are enjoyable globally for their culinary value and are increasingly considered alternative protein sources. However, the skin of edible amphibians, especially giant salamanders, is often discarded without much thought. However, this underutilized resource holds significant potential for yielding valuable proteins and bioactive peptides (BPs). These peptides, such as brevinins, bombesins, dermaseptins, esculentins, magainins, temporins, tigerinins, and salamandrins, possess a wide range of biological activities, including antioxidant, antimicrobial, anticancer, and antidiabetic properties. This review provides a comprehensive analysis of the various BPs derived from giant salamander skin or secretions and their associated biological functions. Furthermore, it examines the nutritional composition of giant salamanders, their production status, and the challenges surrounding the use of their skin and secretions. This review also explores the potential applications of these BPs in the food and biomedical industries, particularly as multifunctional food additives, dietary supplements, and drug delivery agents.

With the exponential growth of the world population and the decline in agricultural production due to global warming, it is predicted that there will be an inevitable shortage of food and meat resources in the future. The global meat consumption, which reached 328 million tons in 2021, is expected to increase by about 70% by 2050, and the existing livestock industry, which utilizes limited resources, is having difficulty meeting the demand. Accordingly, cultured meat produced by culturing cells in the laboratory, edible insects consumed after cooking or processing, and plant-based meat processed by extracting proteins from plants have been proposed as sustainable food alternatives. These future protein sources are gaining popularity among consumers who prefer a healthy diet due to their nutritional benefits, and they are receiving attention for their potential to reduce environmental impact. This review describes the types and characteristics of protein sources such as cultured meat, antiserum media, edible insects, soy protein, wheat protein, and other mushroom mycelia, processing processes and technologies, market status, institutional challenges and prospects, and mushroom cultured meat.

Meat analogs are a burgeoning industry, with plant-based meat analogs, insect-based meat analogs, algae-based meat analogs, mycoprotein-based meat analogs, and cell-based meat analogs. However, despite the industry's growth potential, market expansion faces hurdles due to taste and quality disparities compared to traditional meats. The composition and characteristics of meat analogs currently available in the market are analyzed in this study to inform the development of future products in this sector. The results show that plant-based meat analogs are mainly based on soy protein together with wheat gluten and methylcellulose or spices. Insect-based meat analogs tend to contain processed larvae as the protein source. Seaweed or spirulina is often the main ingredient in algae-based meat analogs. Mycoprotein-based meat analogs all use mycoproteins. Cell-based beef, pork, chicken, and seafood products are already under various stages of development around the world, although many are still at the prototype level.

Animal-based foods such as meat, dairy, and eggs contain abundant essential proteins, vitamins, and minerals that are crucial for human nutrition. Therefore, there is a worldwide growing demand for animal-based products. Since animal-based foods are vital resources of nutrients, it is essential to ensure their microbial safety which may not be ensured by traditional food preservation methods. Although thermal food preservation methods ensure microbial inactivation, they may degrade the nutritional value, physicochemical properties, and sensory qualities of food. Consequently, non-thermal, ultrasound food preservation methods are used in the food industry to evaluate food products and ensure their safety. Ultrasound is the sound waves beyond the human audible range, with frequencies greater than 20 kHz. Two types of ultrasounds can be used for food processing: low-frequency, high-intensity (20-100 kHz, 10-1,000 W/cm²) and high-frequency, low-intensity (>1 MHz, <1 W/cm²). This review emphasizes the application of ultrasound to improve the microbial safety of animal-based foods. It further discusses the ultrasound generation mechanism, ultrasound technique for microbial inactivation, and application of ultrasound in various processing operations, namely thawing, extraction, and emulsification.

Meat analogs or meat alternatives mimic conventional meat by using non-meat ingredients. There are several reasons for the rising interest in meat alternatives, e.g., health-consciousness, environmental concerns, and the growing demand for sustainable diets. Factors like low-calorie foods, low-fat, efforts to reduce greenhouse gas emissions, and flexitarian lifestyles are also contributing to this change (conventional to meat analogs). Numerous meat substitutes are presently being launched in alternative meat markets. Plant-based meat, restructured meat, cultured meat, hybrid cultured meat, and insect protein-based meat are prevalent among meat alternatives. The scope of meat alternatives, including plant-based meat, cultured meat, restructured meat, and insect-based protein products, is expanding due to advances in food technology. Innovation in food technology plays a crucial role in sustainable food production. Still, there are some challenges to the market of meat alternatives, including consumer acceptance, the appearance of meat alternatives, and the cost of production. Innovative approaches, such as advanced technologies and awareness of meat alternatives to the meat consumer, are required to deal with these challenges. This review briefly examines the technological advances, regulatory requirements, pros and cons, and market trends of meat alternatives. The finding of this review highlights the importance of meat alternatives as a sustainable resource of food. Moreover, meat alternatives can fulfill the increasing demand for meat and also decrease the environmental impact. Additionally, this review also explores ways to improve the overall market scenario of meat alternatives.
