摘要
根据食品营养学范畴的化学动力学原理,将产品置于高温、高湿,即温度(37±2)℃,湿度(75±5)%的条件下存放6个月。通过加快营养衰减变质速度并定期检测关键营养素指标以及限量指标,确定该条件下营养物质的稳定性。加速试验结果显示,营养素指标与限量指标无明显变化。奶粉贮藏过程中脂肪易氧化酸败,建议以后的加速试验中考虑脂肪氧化指标以及直接接触的包装材料可能含有的污染物。
According to the principles of chemical kinetics of food nutrition, the product was placed in high temperature and high humidity which temperature was at(37 ± 2) ℃ and humidity was at(75 ± 5)% for 6 months. The stability of nutrients under the conditions was determined by accelerateing nutrient decay speed and measuring the key nutrient indicators and limit indicators. The results of accelerated experiments showed no significant changes in nutrient and limit indicators. During the storage of milk powder, the fat is easily oxidized and rancid. Therefore, it was recommended to consider the fat oxidation index and the contaminants that directly contacted packaging material into account in the acceleration test.
