DEVELOPMENTS OF SAFE FOOD PRODUCTION SYSTEM BASED ON PREDICTIVE MICROBIOLOGY

食品安全是近年来公众日益关注的问题。为了实现微生物食品安全，预测微生物学和传热学模型的结合是一个新兴的重要的新领域，在食品加工行业有着广泛的应用。基于动态预测的概念，我们开发了食品加工中的一些食品安全评估工具：(1)从食品安全的角度发展冷藏设计优化方法；(2)微生物生长/失活的随机预测模型；(3)食品加工表面生物膜形成的研究；(4)食品加工中微生物失活和去除方法的发展。

Food safety is a public concern increasing in recent years. For achievement of microbiological food safety, the combination of predictive microbiology and heat transfer modeling is an emerging and important new field with broad applications to the food processing industries. Based on the concept of dynamic prediction, we developed some food safety assessment tools in food processing as follows : (1) development of design optimization method for cold store from a food safety standpoint ; (2) development of a stochastic prediction model for microbial growth/inactivation ; (3) investigation of biofilm formation on food processing surfaces ; (4) development of microbial inactivation and removal methods in food processing.
