The food we consume plays an important role in our daily life. It provides us energy which is needed to work, grow, be
active, and to learn and think. The healthy food is essential for good health and nutrition. Light, oxygen, heat, humidity,
temperature and spoilage bacteria can all affect both safety and quality of perishable foods. Food kept at room temperature
undergoes some chemical reactions after certain period of time, which affects the taste, texture and smell of a food. Consuming
spoiled food is harmful for consumers as it can lead to foodborne diseases.
