The conventional thermal processing has long been applied to preserve various food materials in the food industry. Thermal processing applies heat for reducing the population of microorganisms in the product and extends its shelf life as a consequence. In this chapter, the target microorganisms in high-acid/acid and medium-acid or low-acid foods, basic theory of thermal death time calculation, the concept of commercial sterilization, the conventional canning operation for fruit products, and the possible deterioration in the storage of canned fruit products will be described.
