Describe why food spoils. Food spoilage can be defined as a disagreeable change in a food’s normal state. Such changes can be detected by smell, taste, touch, or sight. These changes are due to a number of reasons — air and oxygen, moisture, light, microbial growth, and temperature.
What happens to a food during spoilage?
When food items kept for a long time gets spoil as germs start growing on it. Once the food is spoiled, it cannot be eaten and has to be thrown away. Spoilage is a process in which food items deteriorate to the point in which it is not edible to human.
Which type of change takes place when food gets spoiled?
The two major chemical changes which occur during the processing and storage of foods and lead to a deterioration in sensory quality are lipid oxidation and non-enzymatic browning. Chemical reactions are also responsible for changes in the colour and flavour of foods during processing and storage.
How does food get Spoilt answer?
Factors that can cause food to spoil include microbial, chemical and physical reactions which affect the taste, smell and appearance of a product. Microorganisms are common in foods, especially bacteria, yeasts and molds.
Why it is important to know the causes of food spoilage?
Knowing the causes of food spoilage can help you avoid foodborne illness. Air and light can cause changes to our food that can make it become rancid. Oxidation can occur creating a discoloration, flavor change and even change the nutrient content of the food.

Food spoilage is the process leading to a product becoming either undesirable or unacceptable for human consumption (with associated changes involving alterations in taste, smell, appearance or texture).
Is food spoilage a physical change?
1.1 Introduction. Food spoilage results when microbiological, chemical, or physical changes occur, rendering the food product unacceptable to the consumer.

What are the causes of food deterioration and spoilage?
Various factors cause food spoilage, making items unsuitable for consumption. Light, oxygen, heat, humidity, temperature and spoilage bacteria can all affect both safety and quality of perishable foods. When subject to these factors, foods will gradually deteriorate.
What are physical changes that occur during food processing?
During food processing and preservation, various physical changes (e.g., melting, crystallization, glass transition) occur in food products, affecting their quality. This chapter specifically examines the effect of physical changes on the quality of dry and frozen food products.
Why do foods deteriorate?
