[目的]探索贮存期内纯牛奶粒径的变化,从而对纯牛奶的口感和质量变化情况进行监控。[方法]对纯牛奶样品进行前处理后,利用粒径检测仪对纯牛奶进行测定,选择不同时间间隔的纯牛奶样品进行比较研究。[结果]短期保质期贮存时间纯牛奶粒径变化不明显,总体上保持在较稳定的状态;长期保质期贮存时间纯牛奶粒径值随时间的延长出现了显著增长。[结论]通过对短期保质期产品和长期保质期纯牛奶样品粒径变化的研究,得出粒径值的变化对纯牛奶的保质期内稳定性有明显的影响,为其他相关产品保质期制定和稳定性的监控提供参考。

[Objective] To explore the changes in the particle size of pure milk during its storage period in order to monitor the changes in the taste and quality of pure milk.[Method]After pre-treatment of pure milk samples,a particle size detector was used to measure pure milk, and pure milk samples at different time intervals were selected for comparative study.[Result] The short-term shelf life storage time shows no significant change in the particle size of pure milk,and overall it remains in a relatively stable state.The long-term shelf life storage time showed a significant increase in the particle size value of pure milk over time. [Conclusion] By studying the changes in particle size of short-term and long-term shelf life pure milk samples,it was found that the changes in particle size values have a significant impact on the stability of pure milk during its shelf life,providing reference for the formulation of shelf life and monitoring of stability for other related products.
