Detailed explanation-1: -Spoiled food is generally more a problem of appearance than a problem of disease causing. In food spoilage, the changes in appearance or texture of the food, such as rottenness, softness and change in colour, taste or odour are usually obvious, whereas in contaminated food such characteristics may not be noticed.
Detailed explanation-2: -Foods that deteriorate and develop unpleasant odors, tastes, and textures are spoiled. Spoilage bacteria can cause fruits and vegetables to get mushy or slimy, or meat to develop a bad odor.
Detailed explanation-3: -Food spoilage is indicated by changes in colour from orange to yellow to green. An orange colour means that the product is only roughly half as fresh, and is edible for only for a period of another seven days if kept refrigerated. The tags were tested and developed using E coli in milk as a reference model.
Detailed explanation-4: -Change in texture: Some vegetables like potato, brinjal and carrot undergo too much softening leading to rotting. Change due to mechanical damage: Mechanical damages such as eggs with broken shells, mechanical spoilage of fruits and vegetables during transportation also constitute food spoilage.
