摘要： 为了掌握初乳清粉的贮藏特性,采用货架期预测方程来估计初乳清粉在室温(25℃)、50％相对湿度(RH)条件下PET包装的货架期,并对90d贮藏期过程中其理化指标以及生化指标的变化进行研究.研究结果表明:在PET包装90d贮藏时间内,初乳清粉的水分含量、硫代巴比妥酸(TBA)值和羟甲基糠醛(HMF)含量均随贮藏时间的延长而显著增加(P＜0.05),色差随贮藏时间的延长有所波动,但总体呈现上升趋势,而免疫球蛋白(IgG)的含量在60d内逐渐降低,60d后其下降不显著；在25℃、50％ RH条件下PET包装的初乳清粉的货架期为99.40d.

Abstract: The present study aimed at understanding the storage stability of bovine colostrum whey powder. Moreover, a predictive equation to estimate its shelf life under the conditions of ambient temperature (25 ℃), 50% relative humidity (RH) and packaging in PET bags was presented. The evolution of some key physicochemical and biochemical parameters was studied over a storage period of 90 days. The results obtained in this study indicated that the contents of water and HMF and TBA value in bovine colostrum whey powder packaged in PET bags significantly increased over time during the storage period (P ＜ 0.05) and color difference also showed an increasing trend, even though with some fluctuations, while IgG level conversely exhibited a decreasing trend in the first 60 days, followed by no significant decrease. Under the storage conditions used in this study, the shelf life of bovine colostrum whey powder was 99.40 days. The findings of this study can provide basic data for industrial production of bovine colostrum whey powder.
