Shelf-life Prediction and Nutrients Change Analysis during Shelf-life of Infant Rice Cereal

Two external environments (37℃ 75% RH and 47℃ 75% RH) were set up to predict the shelf-life and analyze the nutrient decay of infant rice cereal. The results indicated that the shelf-life of infant rice cereals packed by nitrogen-filled iron was 722~841 d at 25℃ 75% RH which was calculated by the shelf-life at 37℃ 75% RH (210~225 d) and 47℃ 75% RH (75 d). The stability of vitamin A and pantothenic acid were the worst and the highest decay rates were 28.96% and 24.47%, respectively. And the stability of vitamin B₁, vitamin B₂, folic acid, vitamin E and vitamin C were poor and the highest decay rates were 18.46%, 18.97%, 18.53%, 13.96% and 12.67%, respectively. The stability of vitamin D, vitamin B₆, vitamin B₁₂, niacin, biotin and iron were best with almost no decay during shelf-life.
