These products are composed of a variety of blended ingredients, any of which can contribute microorganisms to the food. Yeasts and bacteria are the most common causes of spoilage, which is usually manifest in 3 ways: A. Slimy spoilage
Microorganisms occur everywhere in the environment, and there is always a risk of spoilage when foods are exposed to unsuitable conditions. Microbial spoilage results from bacteria, molds, and yeast. While microorganisms may or may not be harmful, the waste products they produce when growing on or in food may be unpleasant to taste.
Microbial Food Spoilage can define the biological process which involves microorganisms can degrade and decompose the food material, at optimal environmental conditions (temperature, ph, oxygen, moisture etc.) and brings some undesirable changes which make the food inedible to eat.
Food spoilage refers to undesirable changes occurring in food due to the influence of air, heat, light, moisture, which foster the growth of microorganisms. Foods take different period of time to lose their natural form though spoilage.
Food spoilage is caused by bacteria, yeasts, fungi, the food's own enzymes, insects, temperature fluctuation and oxidation. When eaten, food that is spoiled by bacteria or other microbes presents a disease hazard to humans.
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. Factors that affect food spoilage include:
Food spoilage is the process where a food product becomes unsuitable to ingest by the consumer. The cause of such a process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored. Due to food spoilage, one-third of the worlds' food produced for the consumption of humans is lost every year.
single cause of food spoilage is invasion by microorganisms such as moulds, yeast and bacteria. In case of mould spoilage a furry growth covers the food and it becomes soft and often smells bad. Bacterial contamination is more dangerous because very often food does not look bad even though severely infected, it may appear quite normal. The
Micro-organisms, in relation to food, can have one of these 3 roles: Pathogenic micro-organisms can cause infections or intoxications; Saprophytic micro-organism play a role in biodegradation and cause food spoilage; Cultured micro-organisms like probiotic bacteria are used in food processing.
Causes of Spoilage. The food and water may be infected by germs. Flies carry germs. When they sit on our food, they pass on these germs to our food. There are various factors which are responsible for food spoilage such as bacteria, mould, yeast, moisture, light, temperature, and chemical reaction. 1. Bacteria.
