Food deterioration and its control pdf
preservation is to control all forms of quality deterioration, the overriding priority is always to minimize the potential for the occurrence and growth of food spoilage and food poisoning microorganisms (ICMSF, 1996). Despite the extensive scientific progress and technological developments achieved in recent years, food safety problems continue to exist and may actually increase in the future

It is not illegal to sell food past its “best before” date unless it has deteriorated. Food with a “best before” date must be labelled as following: • Products with less than a 3-month shelf life must state the day and month on the pack e.g. Best before 6th April • Products with a shelf life between 3 and 18 months must state the month end and year e.g. Best before end June 2016
Food Spoilage. Food spoilage is a complex process, and the type of product (intrinsic parameters) and the way it is packaged and stored (extrinsic parameters) select for the types of spoilage microorganism that can grow quickest under those conditions and hence lead to the spoilage of the product.

Food spoilage and deterioration is no accident. It is a naturally occurring process. To understand how to maintain the quality of food and prevent spoilage, we need to know what can cause it.
“Negative” aspects of microbial growth include food deterioration and spoilage by decay, and food poisoning, mainly caused by different and less widespread bacteria. As they grow, micro-organisms release their own enzymes into the liquid surrounding them, and absorb the products of external digestion. This is the main basis of microbial food spoilage, which lowers its nutritional value
