The study was conducted to identify trends in the use of hormones and antibiotics, and traditional practices in cattle fattening in the southwest coastal region of Bangladesh. Data were collected from 150 farmers involved in beef cattle fattening through a survey questionnaire. The average numbers of cattle and beef cattle per household were 4.27 ± 1.94 and 3.54 ± 1.31, respectively. An average of 44.67 percent of the beef farmers selected indigenous (zebu) cattle and the rest of the farmers kept a variety of crossbred cattle for fattening. The average age of cattle at the start of fattening was 21.61 ± 8.07 months, the average duration of fattening was 9.71 ± 4.29 months, and farmers marketed cattle at an average weight of 285.50 ± 50.80 kg. The highest percentage (34.67%) of farmers ate beef once a week and 5.33 percent of farmers never ate beef. Among beef farmers, 53.33% and 62.67% applied hormones and antibiotics, respectively, to their beef cattle. The highest percentage of farmers used hormones (33.87%) and antibiotics (29.79%) once a week and the rest of the farmers used them at various intervals. The majority of farmers did not follow any withdrawal period before slaughtering beef cattle for application of hormones (85.48%) and antibiotics (83.58%), whereas the remaining farmers maintained different withdrawal periods. It can be concluded that more than half of the farmers applied hormones and about two-thirds of the farmers used antibiotics for beef fattening, and most of the farmers did not follow the recommended withdrawal periods before slaughter, which is of public health concern.

The hazard analysis and critical control point (HACCP) system is a protocol aimed to guarantee food safety, especially in companies dedicated to meat processing. Companies in food international trade are subjected to intense inspection and verification processes, and international standard certifications have become a key factor in global trade. The purpose of this study was a comparative analysis of HACCP certification in the Mexican and Chilean meat packers that send meat to international markets by a field inspection of each to identify opportunities for improvement. International trade standards along with packers’ expectations and needs to be fulfilled to attain a place in world markets were bases for this study. Guidelines for field inspection came from the HACCP protocol. Field data were derived from 15 indicators —  five intrinsic to the HACCP plan and ten external. The Chilean packer was superior to the Mexican packer in terms of many indicators. Thus, the first one had a chance for a better position in international markets than the latter. It was concluded that the HACCP audit is an excellent tool to measure the suitability of meat packers in achieving a place as a supplier and remaining in the international food trade.

The use of pork obtained from intensively growing hybrid animals as the main raw material in meat processing, in particular sausage production, is accompanied by undesirable variability of consumer characteristics of sausage products and a decrease in the economic indicators of enterprise performance. The main technological disadvantages of processed pork are reduced water-binding capacity and significant loss of meat fluid, which in practice is usually compensated by the increased use of food additives and non-meat ingredients. The aim of the study was to assess the possibility of targeted improvement of the technological properties of minced pork using a proteolytic enzyme of animal origin. Model samples of minced meat were developed and cured for 24 hours at a temperature of 4 °C. The following control samples were used: minced meat with the addition of 2% edible salt and minced meat with the addition of 2% edible salt and 0.2% sodium bicarbonate. Moreover, 0.0001% chymotrypsin was added to the test samples containing similar curing ingredients. During electrophoretic study, in samples with the enzyme, an increase in low-molecular fractions (20 kDa, 15 kDa and lower) was observed, which indicated the manifestation of proteolytic activity of chymotrypsin in model systems. Enzymatic treatment led to an increase in pH and water-binding capacity. Cooking loss was reduced by 3 to 6 times, compared to Control 1. After cooking, histological studies of model systems showed that the test samples subjected to enzymatic treatment were characterized by a denser arrangement of structural elements, less pronounced cellular components of muscle tissue and the presence of glutin formed as a result of protein breakdown, filling the microcapillaries. Thus, the use of an enzyme preparation provides an opportunity for targeted improvement of the technological properties of pork obtained from intensively growing hybrid animals.

Processing lamb meat into fermented sausages can reduce the risk of spoilage and extend shelf life. Fermented sausages are commonly made using lactic acid bacteria (LAB), resulting in a product that is acidic and less firm. Therefore, it is necessary to add jack bean flour as a binding agent. This study aims to analyze physicochemical, microbiological and organoleptic characteristics of premium IPB lamb fermented sausages with varying proportions of jack bean flour (0% and 30%). The analyses included pH, water activity (a_w), total acid, water, ash, fat, crude protein, carbohydrate, total LAB, E. coli, S. aureus, texture profile analysis (TPA), and sensory evaluation. The incorporation of jack bean flour into lamb meat fermented sausages can elevate the pH, springiness, chewiness, crude protein, and carbohydrate content of the fermented sausages. Furthermore, the addition of jack bean flour may reduce the total acid, a_w, gumminess, water content, and bacteria (E. coli and S. aureus). The sensory aspects such as color in fermented sausage with addition of jack bean flour were preferred by the panelists. The addition of jack bean flour increased the total unsaturated fatty acids and essential amino acids in fermented sausages. The incorporation of jack bean flour aligns with the Indonesian National Standards for Meat Sausages 3820–2015 concerning moisture, fat, and protein content. This study suggests that incorporating lamb fermented sausage with 30% jack bean flour could result in significant benefits, including increased nutrition, enhanced sensory quality, improved texture, and extended storage life for fresh lamb products.

The demand for safe, high-quality meat products drives the need for effective antimicrobial solutions to combat bacterial contamination, a significant health and economic concern. Synthetic preservatives face increasing scrutiny, leading to interest in natural alternatives such as coriander (Coriandrum sativum L.). Known for its culinary and medicinal uses, coriander essential oils, particularly linalool and pinene, exhibit strong antimicrobial properties against a wide range of pathogens. This review examines the phytochemical composition and antimicrobial mechanisms of coriander, and its practical applications in meat preservation through a One Health perspective, which addresses the interconnectedness of human, animal, and environmental health. Coriander offers unique benefits such as a milder flavor and cost-effectiveness. Despite challenges, including variability in antimicrobial efficacy and sensory impacts, its safety profile and regulatory status support its use. Future research should optimize extraction methods, explore synergies with other preservatives, and evaluate long-term safety and efficacy. Coriander is a viable natural solution for improving food safety and quality in the meat industry, aligning with One Health objectives by promoting sustainable practices and reducing health risks across the food production continuum.

The pancreas gland (PG) is a secondary product of livestock processing; it contains a wide range of biologically active compounds. The purpose of this article is to analyze the efficiency of technological approaches for pancreas gland extraction with the help of trehalose and a glycine-proline mixture aimed for recovery and separation of the gland’s protein-peptide compounds. The extraction was conducted with 0.9% NaCl, 0.9% NaCl, with addition of 0.5 M trehalose (0.9% NaCl-0.5 M trehalose) and 0.9% NaCl with addition of 1% glycine and 0.1 M L-proline (0.9% NaCl-1% Gly-0.1M Pro), the ratio of pancreas gland to extractant was equal to 1:5. The concentration of the protein in the supernatants after their extraction was measured by the biuret reaction in a semi-automatic biochemical analyzer Biochem SA. The proteomic composition of the extracts and the native pancreas gland was assessed by one-dimensional Laemmli electrophoresis in a 12.5% polyacrylamide gel and by two-dimensional O’Farrell electrophoresis. When determining the intensity of the protein fractions, it was noted that the methodology of separation of protein-peptide mixtures extracted from the pigs pancreas gland with the extractant 0.9% NaCl-1% Gly-0.1M Pro, ensured the higher extraction of the proteins in comparison with the method of 0.9% NaCl-0.5 M trehalose. Notwithstanding the fact that application of amino acids (glycine and proline) mixture provided for a greater yield of proteins from the extract into the diafiltrate, the experiments in vitro showed that the diafiltrate obtained though trehalose featured higher activity. This may be explained by the fact that after dialysis removal of trehalose from the protein fraction with a molecular weight of less than 50 kDa, its residual quantities were still sufficient to prevent proteins aggregation and, as a consequence, the biological activity of the extracted proteins was preserved, while in the diafiltrate obtained through amino acids mixture where numerous protein aggregates were detected by 2-DE. This study allowed testing the biotechnological methodics on pig pancreatic tissues aimed to intensifying the extraction and separation of protein compounds. The results of the study are important for development of methodological approaches to obtaining the targeted substances for their further utilizing for various purposes.

The freshness or spoilage of meat is critical in terms of meat color and quality criteria. Detecting the condition of the meat is important not only for consumers but also for the processing of the meat itself. Meat quality is influenced by various pre-slaughter factors including housing conditions, diet, age, genetic background, environmental temperature, and stress factors. Additionally, spoilage can occur due to the slaughtering process, though post-slaughter spoilage is more frequent and has a stronger correlation with postslaughter factors. The primary indicator of meat quality is the pH value, which can be high or low. Variations in pH values can lead to adverse effects in the final product such as color defects, microbial issues, short shelf life, reduced quality, and consumer complaints. Many of these characteristics are visible components of quality. This study aimed to develop a mobile application using deep learning-based image processing techniques for the rapid detection of freshness. The attributes of the source and the targeted predictions were found satisfactory, indicating that further advancements could be made in developing future versions of the application.

The algorithm of methodology is a sequence of stages executed during the product development and a description of their content and practical implementation. The modern approaches to creation of healthy food products for people with socially significant diseases, the recommendations of the World Health Organization based on the analysis of scientific literature posted in open sources and publicly available databases were used as the material of the research, as well as the results of our own studies in the field of technologies for dietary therapeutic and prophylactic nutrition meat products. The specialized meat products for therapeutic and prophylactic nutrition, information about their ingredient composition, nutritional value, results of preclinical and clinical trials were used as the objects of the study. The stages of product creation include medical and biological substantiation of the composition, designing of a virtual model of the food product, technology development, evaluation of the safety and efficiency of the resulting product taking into consideration the technological impact, preclinical and clinical evaluation. The study showed the difference in the approaches to the dietary meat products development depending on the purpose —  whether its therapeutic nutrition or prophylactic nutrition. The developed methodology can be used as a tool that provides for scientifically justified development of the specialized meat products and substantiation of their efficiency.

In the past few years, lifestyle-related diseases have been increasing, and meat intake has been linked to this increase. Therefore, in recent years, there have been attempts to use soybeans as a substitute for meat. Soybeans exhibit antioxidant and antimicrobial effects. Therefore, processing foods using soybeans may preserve food quality because the main factors causing food deterioration are oxidation and microbial growth. To verify the quality-retention effect of soybeans, we conducted a sensory test on hamburgers, the quality of which readily deteriorates over time. We investigated the percentage of soybean meat that would be acceptable in a hamburger and quality retention with the addition of different amounts of soybean meat. We found that hamburgers with soybean meat were accepted by more than half of the participants when the soybean meat content was ≤50%. In terms of changes over time in quality-related factors, the L- and b-values (lightness/brightness and yellowness/blueness, respectively) were higher, avalue (redness/greenness) was lower, and pH was higher in hamburgers that contained soybean meat than in those without added soybean meat. Furthermore, an increase in the bacteria count and peroxide content was suppressed in hamburgers containing soybean meat. The results indicate that hamburgers containing soybean meat are of higher quality than those made with 100% animal meat. The use of soybeans as a meat substitute in hamburgers can help mitigate the rise of lifestyle-related diseases linked to high meat consumption.
