Abstract
Food spoilage poses significant challenges to the global food industry, impacting both food safety and economic sustainability. The main causes of food quality deterioration are microbial and non-microbial spoiling. Microbial spoilage primarily results from the activity of bacteria, yeasts, and molds, which thrive under favorable environmental conditions. These microorganisms can lead to food poisoning and spoilage through the production of off-flavors, discoloration, slime formation, and the accumulation of harmful toxins. Factors such as initial contamination levels, the specific type of microorganism, the inherent composition of the food, and storage conditions, including temperature, humidity, and exposure to oxygen, influence the rate of microbial spoilage. Foods with higher moisture content are particularly susceptible, as water activity provides an ideal medium for microbial growth. On the other hand, a number of processes other than microbial action cause non-microbial spoiling. These include moisture loss, which can lead to textural changes and decreased consumer acceptability; chemical changes, such as oxidation of lipids leading to rancidity; and reactions involving enzymes naturally present in foods. Additionally, external factors such as light exposure can accelerate the degradation of sensitive nutrients, while physical damage during handling or transportation can compromise the structural integrity of food, making it more prone to spoilage. Temperature fluctuations during storage or distribution also play a critical role, as they can promote both microbial activity and undesirable chemical reactions. To mitigate these spoilage mechanisms and ensure the safety and quality of food products, comprehensive evaluation methods are employed. Sensory evaluations, such as visual inspection, odor analysis, and taste testing, are often the first line of defense in detecting spoilage. Microbiological analyses, including total plate counts, identification of spoilage organisms, and detection of microbial toxins, provide more detailed insights into microbial contamination. Furthermore, advanced physical and chemical tests, such as moisture content determination, lipid oxidation assays, and the use of spectroscopic techniques, enable the quantification of spoilage indicators. These methodologies not only assess the current state of food quality but also play a crucial role in determining self-life. Shelf life determination is a critical component of food preservation strategies. By understanding the rate and nature of spoilage under controlled conditions, food producers can establish storage guidelines, optimize packaging materials, and implement preservation techniques such as refrigeration, freezing, drying, or the use of chemical preservatives. Moreover, adherence to food safety standards and regulations ensures that products reaching consumers are both high-quality and safe for consumption. Frameworks for controlling the risks of food spoiling are provided by international standards like ISO 22000 and HACCP (Hazard Analysis Critical Control Points) This review delves into the mechanisms underlying microbial and non-microbial spoilage, the methodologies employed to assess spoilage, and the measures taken to extend shelf life. By highlighting the latest advancements in food preservation technologies and quality control standards, this study aims to provide a comprehensive understanding of food spoilage and its implications for food safety, public health, and the global food supply chain
