    摘要:

    奶制品的纸盒钻石包装越来越流行,但纸盒产品易发生变形破损。为提升产品终端形象,给消费者提供更便捷的产品,研制了高密度聚乙烯瓶装常温酸奶。对高密度聚乙烯瓶装常温酸奶二次杀菌参数可行性、最优参数进行了研究。利用L9(34)正交试验,分析了酸奶感官品评、黏度及微生物检测结果并对贮存试验期间各项指标进行了测定。结果显示:75℃,20min二次杀菌是高密度聚乙烯瓶装酸奶产品的优化参数,该产品在常温条件下可贮存90d。

    Abstract:

    The cartons diamond packaging market becomes more and more popular, but carton products by their own limitations (such as going out to carry, improper preservation, etc.) is prone to the deformation and damage. To enhance the image of the terminal product,and provide consumers with more convenient products, high density polyethylene (HDPE ) bottles for yogurt at room temperature were studied. In this study, the feasibility and optimal parameters of the secondary sterilization of the room temperature yoghurt in high density polyethylene bottle were studied. The sensory evaluation, viscosity, and microbial test results of the yogurt were determined by the L9(34) orthogonal test with the temperature and time as factors. The results showed that the optimal parameter for HDPE bottled yogurt was the 75℃, 20min secondary sterilization and the shelf-life of yogurt was 90 days.
