This article discusses the issues of food safety and food security as a matter of global health. Foodborne illness and deaths caused by pathogens in food continue to be a worldwide problem, with a reported 600 million cases per year, leading to around 420,000 deaths in 2010. Predictive microbiology can play a crucial role in ensuring safe food through mathematical modelling to estimate microbial growth and behaviour. Food security is described as the social and economical means of accessing safe and nutritious food that meets people's dietary preferences and requirements for an active and healthy life. The article also examines various factors that influence food security, including economic, environmental, technological, and geopolitical challenges globally. The concept of food safety is described as a science-based process or action that prevents food from containing substances that could harm human health. Food safety receives limited attention from policymakers and consumers in low- and middle-income countries, where food safety issues are most prevalent. The article also highlights the importance of detecting contaminants and pathogens in food to prevent foodborne illnesses and reduce food waste. Food and Agriculture Organization (FAO), an institution belonging to World Health Organization (WHO) presented calls to action to solve some of the emerging problems in food safety, as it should be a concern of all people to be involved in the pursue of safer food. The guarantee of safe food pertaining to microbiological contamination, as there are different types of active microorganisms in foods, could be obtained using predictive microbiology tools, which study and analyse different microorganisms' behaviour through mathematical models. Studies published by several authors show the application of primary, secondary, or tertiary models of predictive microbiology used for different food products.

Foodborne pathogens remain a significant global challenge, contributing to widespread illness and considerable food losses. This study investigates the effects of electron-beam irradiation on beef quality and safety using a pulsed high-frequency linear accelerator (ILU-10). Meat samples were subjected to irradiation at doses of 3, 6, and 9 kGy, with non-irradiated samples serving as controls. The research focused on evaluating microbial reduction, alterations in textural properties, and changes in nutritional components including amino acids, vitamins, and mineral content. Microbiological analysis demonstrated a dose-dependent reduction in total viable counts, with a decrease from 300 CFU/g in controls to 100 CFU/g at 3 and 6 kGy and complete microbial inactivation at 9 kGy. Scanning electron microscopy revealed disruption in myofibrillar structure, with increased interstitial spacing. Chemical analyses indicated a dose-dependent decline in total amino acid content and variable responses among individual amino acids, suggesting irradiation-induced protein fragmentation and oxidation. The findings suggest that, when optimized, irradiation can substantially improve meat safety while maintaining acceptable nutritional and sensory quality.

Growing consumer demand for healthier meat products with clean-label ingredients has increased interest in plant-based fortification strategies. The present study evaluated the effects of a multicomponent cereal supplement comprising rice (35%), buckwheat (20%), oats (20%), and corn (25%) on the physicochemical, functional, oxidative, hydrolytic, and sensory properties of meat patties. Four formulations were prepared with 0% (control), 5%, 10%, and 15% supplement inclusion. At higher inclusion levels of the cereal supplement, the patties showed reduced moisture, protein, and fat contents, while ash and carbohydrate levels increased. Conversely, ash content increased from 1.38% to 2.82%, and carbohydrates rose to 8.99%. pH remained stable (5.92–6.04), whereas aw decreased significantly at 10% (0.921) and 15% (0.889) inclusion (p < 0.05). Functional tests showed dose-dependent improvements in water-binding capacity, which increased from 65.98% in the control to 71.58% at 10% supplement, and in fat retention, which rose from 38.3% to 54.14% under the same conditions, with optimal performance observed at 10% inclusion. TBARS values in 10% and 15% formulations were 13–20% lower than control throughout storage (p < 0.05). The increase in acid number was significantly slower in supplemented patties, indicating that the cereal blend effectively inhibited lipid hydrolysis during storage. Sensory evaluation revealed maximal acceptability at 10% inclusion, with declines at 15% due to grainy texture and flavor dilution. These findings establish 10% multicomponent cereal supplementation as a promising strategy to enhance yield, shelf-life stability, and consumer appeal of meat patties without compromising processing parameters.

This study developed enriched kurt formulations using buttermilk protein sediment, spray-dried whey, soy protein concentrate, and flaxseed cake, and assessed their effects on composition, physicochemical parameters, microbiological stability, and sensory quality. Protein content increased from 46.2% in the control to 48.7–52.4% in experimental samples. Calcium levels rose from 750 mg/100 g to 856 mg/100 g in Experiment 1 and 880.7 mg/100 g in Experiment 3 (p < 0.05), demonstrating strong mineral enhancement. Moisture decreased from 13.61% in the control to 11.68–12.90% in enriched variants (p < 0.05), indicating more efficient dehydration and a denser structure. pH remained within 4.1–4.3 and water activity stayed below 0.60, supporting long-term microbial stability. Amino acid profiling showed higher levels of essential amino acids, particularly leucine and lysine, in samples containing buttermilk protein sediment and whey. Microbiological analysis confirmed low total viable counts values (9.0 × 10²–1.2 × 10³ CFU/g), consistent with the high acidity and low moisture of traditional kurt. Sensory evaluation revealed significant variation among formulations. The control and Experiment 2 received the highest taste and aroma scores (4.67 points), while Experiment 3 showed the lowest values (3.33 points; p < 0.05). Appearance scores decreased notably in darker samples, with Experiment 3 showing a reduction from 4.67 to 2.67 points (p < 0.05). Texture also differed across variants; Experiment 2 maintained acceptable hardness and cohesiveness (4.33 points), whereas Experiment 3 displayed increased crumbliness (3.0 points; p < 0.05). The findings demonstrate that functional enrichment of kurt is feasible when ingredient levels remain within an optimal range. The Experiment 2 formulation achieved improved nutritional value without compromising sensory quality, providing a promising basis for further technological development and commercial application.

This study focused on developing a nutritionally enhanced turkey meat pate, incorporating plant-based ingredients like flaxseed and hemp flour. Two canned pate samples were produced: a control sample with turkey meat, liver, heart, fat, skin, beans, onions, and spices, and an experimental sample where 20% of turkey meat was replaced with duck meat, and beans were substituted with zucchini, flaxseed, and hemp flour. The experimental pate showed significant differences in chemical composition compared to the control. It had lower moisture and fat content but higher protein, ash, and carbohydrate content. The energy value slightly decreased from 153.01 kcal/100g to 146.9 kcal/100g. The sensory evaluation found similarities in appearance, consistency, and colour, with the experimental pate receiving a slightly higher colour rating. The amino acid profile of the experimental pate was significantly altered, with increases in methionine, isoleucine, threonine, glutamic acid, alanine, and cysteine. Vitamin and mineral content also significantly increased, particularly vitamins A, D, E, and B group vitamins, calcium, potassium, magnesium, and iron. Microscopic analysis revealed a more heterogeneous microstructure in the experimental pate due to the plant ingredients. This research demonstrates the potential of developing a healthier turkey meat pate using plant-based ingredients, catering to the growing demand for healthier food options.
