e, each additional 10 ℃ respiration rate will increase by 1 to 1.5 times or more.Respiratory greater the intensity, the greater the consumption of materials, storage life is shorter.Heat generated by respiration crops will accelerate its maturity and even corruption, appear unwilling to see the shape, color and soften the tissue changes, breathing heat can also cause changes in metbolism, affecting product taste and nutrition.In the range of 30 ℃ ~ 60 ℃, fungi, bacteria and various microorgan
