This study investigated the health risks associated with aflatoxins (AFs) in processed meat products (PMP) sold in Riyadh, Kingdom of Saudi Arabia. The occurrence and levels of AFs were assessed using high-performance liquid chromatography with fluorescence detection (HPLC-FD), whereas the cancer risk attributed to the consumption of meat products containing AFs was estimated by means of margin of exposure (MOE) on a scale of 100-600, representing high and low exposure, respectively. The results indicated that 37.5% of the samples were contaminated, with concentrations ranging from 0.30 to 52.93 μg/kg, at an average of 6.4 ± 12.58 μg/kg. The percentage contamination levels with total AFs higher than the permissible Saudi limit of 20 μg/kg were 4% of samples analysed and 10% of contaminated samples. AFB1 and AFG1 were the most prevalent toxins, followed by AFB2; AFG2 was not detected in any sample. The MOE was found to be 175 and 311 for total AFs in processed beef meat and poultry meat products, respectively. These results showed that the daily intake of AF-contaminated PMP may constitute a public health concern. To our knowledge, this is the first study to report the health risk associated with PMP contaminated with AFs.

Exploring the Future of Extrusion with Andean Grains: Macromolecular Changes, Innovations, Future Trends and Food Security.

Facultad de Industrias Alimentarias, Universidad Nacional Agraria La Molina, Lima, Peru.
This review aimed to explore the impact of extrusion on Andean grains, such as quinoa, kañiwa, and kiwicha, highlighting their macromolecular transformations, technological innovations, and contributions to food security. These grains, which are rich in starch, high-quality proteins, and antioxidant compounds, are versatile raw materials for extrusion, a continuous and efficient process that combines high temperatures and pressures to transform structural and chemical components. Extrusion improves the digestibility of proteins and starches, encourages the formation of amylose-lipid complexes, and increases the solubility of dietary fiber.

Collagen-rich meat processing by-products have potential utilization value. Extracellular protease Hap from meat-borne Aeromonas salmonicida has been identified as an ideal protease for hydrolyzing collagen. Here, to explore the possible application of Hap for giving chicken by-products a high added value, the hydrolysis ability and mechanism were investigated.

This experiment was conducted to evaluate the effects of replacing soybean meal (SBM) with cottonseed meal (CSM) on growth performance, carcass trait, intestinal development and intestinal microbiota of broilers. A total of 792 one-day-old male Ross 308 broiler chickens were randomly allotted to three treatment groups, with 8 replicates per group and 33 birds per replicate. The control birds were administered a diet consisting primarily of corn and soybean meal.

The increasing popularity of sous-vide (SV) cooking necessitates research into the microbiological quality, sensory changes, and shelf life of SV products. Studies show that SV cooking significantly reduces the levels of meat microbiota and pathogens, positively affecting the shelf life and safety of SV products. However, the meat spoilage organism Clostridium estertheticum can survive SV cooking as it can produce heat-tolerant spores.

Background: Knowledge about the diet quality among youth who follow different types of plant-based diets is essential to understand whether support is required to ensure a well-planned diet that meets their nutritional needs. This study aimed to investigate how food groups, macronutrient intake, and objective blood measures varied between Norwegian youth following different plant-based diets compared to omnivorous diet.
Methods: Cross-sectional design, with healthy 16-to-24-year-olds (n = 165) recruited from the Agder area in Norway, following a vegan, lacto-ovo-vegetarian, pescatarian, flexitarian or omnivore diet.
