Types of spoilage. Various physical, chemical, and biological factors play contributing roles in spoilage. For instance, microorganisms that break down fats grow in sweet butter (unsalted butter) and cause a type of spoilage called rancidity. Certain types of fungi and bacteria fall into this category. Species of the Gram-negative bacterial rod Pseudomonas are major causes of rancidity. The microorganisms break down the fats in butter to produce glycerol and acids, both of which are responsible for the smell and taste of rancid butter. Another example occurs in meat, which is primarily protein. Bacteria able to digest protein (proteolytic bacteria) break down the protein in meat and release odoriferous products such as putrescine and cadaverine. Chemical products such as these result from the incomplete utilization of the amino acids in the protein. Food spoilage can also result in a sour taste. If milk is kept too long, for example, it will sour. In this case, bacteria that have survived pasteurization grow in the milk and produce acid from the carbohydrate lactose in it. The spoilage will occur more rapidly if the milk is held at room temperature than if refrigerated. The sour taste is due to the presence of lactic acid, acetic acid, butyric acid, and other food acids. http://www.cliffsnotes.com/WileyCDA/CliffsReviewTopic/Food-Spoilage.topicArticleId-8524,articleId-8516.html
factor effecting on food spoilage
The three main types of microorganisms involved in food spoilage are bacteria, yeasts, and molds. Bacteria, such as Salmonella and E. coli, can cause foodborne illnesses and spoilage through decomposition. Yeasts, like Saccharomyces cerevisiae, often lead to fermentation and spoilage in sugary foods. Molds, including species like Aspergillus and Penicillium, grow on food surfaces, causing visible decay and producing mycotoxins.

Louis Pasteur conducted his experiments on the spoilage of food in the 1860s. His groundbreaking work demonstrated that microorganisms cause food spoilage and spoilage can be prevented through processes such as pasteurization. This research significantly advanced the field of microbiology and food preservation.
There are enzymes that speed up the chemical reaction components in food which leads to spoilage. Enzymes can be slowed down so that food spoilage doesn't occur as quickly by keeping food in cold temperatures.
A poisonous spoilage is a poison food that cant be eaten now
based on the ease of spoilage food is classified into 3 :-high perishable food -semi perishable food -non perishable food
preservatives
When the original nutritive value, flavor, texture of the food is damaged, it is known as nutritive food spoilage. When this occurs, the food becomes unsuitable to consume.
