Milk is an ideal environment for the growth of microorganisms, especially psychrotrophic bacteria, which can survive under cold conditions and produce heat-resistant enzymes. Psychrotrophic bacteria create the great problem of spoiling milk quality and safety. Several ways that milk might get contaminated by psychrotrophic bacteria include animal health, cowshed hygiene, water quality, feeding strategy, as well as milk collection, processing, etc. Maintaining the quality of raw milk is critically essential in dairy processing, and the dairy sector is still affected by the premature milk deterioration of market-processed products. This review focused on the recent detection and control strategies of psychrotrophic bacteria and emphasizes the significance of advanced sensing methods for early detection. It highlights the ongoing challenges in the dairy industry caused by these microorganisms and discusses future perspectives in enhancing milk quality through innovative rapid detection methods and stringent processing controls. This review advocates for a shift towards more sophisticated on-farm detection technologies and improved control practices to prevent spoilage and economic losses in the dairy sector.
牛奶是微生物生长的理想环境，尤其是嗜冷菌，它们能在寒冷条件下存活并产生耐热酶。嗜冷菌给牛奶质量和安全带来了严重问题。牛奶受嗜冷菌污染的几种途径包括动物健康、牛舍卫生、水质、饲养策略以及牛奶收集、加工等。在乳制品加工中，保持原料奶的质量至关重要，而乳制品行业仍受到市场加工产品过早变质的影响。本综述聚焦于嗜冷菌的最新检测和控制策略，并强调先进传感方法用于早期检测的重要性。它突出了这些微生物给乳制品行业带来的持续挑战，并讨论了通过创新的快速检测方法和严格的加工控制来提高牛奶质量的未来前景。本综述主张转向更复杂的农场检测技术和改进的控制措施，以防止乳制品行业的变质和经济损失。
