What is the classification of foods based on perishability?
Foods can be classified into three main categories based on perishability: non-perishable foods (e.g. dried beans, grains), semi-perishable foods (e.g. fresh produce, bread), and perishable foods (e.g. dairy products, meats). Perishable foods are the most vulnerable to spoilage and require proper storage and handling to prevent foodborne illness.
