01:29Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
01:28Pasteurization and Food Preservation
Pasteurization is a widely employed thermal processing technique designed to enhance the safety and shelf life of perishable food and beverages. By subjecting products to specific high temperatures for controlled durations, this method effectively inactivates pathogenic microorganisms and spoilage enzymes without significantly compromising sensory qualities. The technique has been pivotal in food safety management, especially for consumables susceptible to microbial contamination such as milk,...
01:26Methods of Controlling Food Spoilage
Food spoilage is caused by microbial growth or by chemical and physical changes, all of which affect the taste, texture, and safety of food.Temperature-Based PreservationRefrigeration at 0–4 °C slows microbial growth and enzyme activity, making it ideal for short-term storage. However, certain spoilage organisms—such as psychrotrophs like Listeria monocytogenes—can still proliferate at these temperatures. Freezing below -18 °C further slows biological processes by forming ice crystals, which...
