Research progress in the optimization of thermal sterilization in canned food

At present, excessive sterilization exists in our canned industry, resulting in a decline in food quality.The optimization indicators which were commonly used in thermal sterilization processing were introduced in this paper and the research progress of thermal sterilization optimization according to quality optimal, the minimum energy consumption and multi-objective optimization were also reviewed. Base on the above, some problems in this field were summarized and analyzed.
