微波灭菌在食品行业中的作用 Effect of microwave sterilization in food industry

微波杀菌技术由于所需时间短，因而可以很大程度的保持食品的营养成分，且杀菌效果显著，可以使食品不使用防腐剂而延长保存期。由于其优于传统的食品加工方法，微波杀菌技术最近越来越受到人们的重视，在食品行业中得到许多应用。

    微波杀菌在具体食品中的研究和应用已有很多相关报道。昆明理工大学张博士等人用微波处理鲜牛奶30秒，就可以达到细菌总数的质控标准；处理90秒后则可以将大肠杆菌等彻底杀灭，且保存3天后仍未见细菌生长，不仅其营养成分保持不变，而且经微波处理作用后，牛奶中的脂肪球直径变小，增加了奶香味，提高了产品的稳定性，有利于营养成分的吸收。梁博士等人以冬瓜和赤豆馅料为试样，研究两种馅料的最佳微波杀菌工艺，为解决馅料制品保鲜瓶颈和延长馅料制品保质期提供理论依据。实验结果表明微波功率越大，照射时间越长，灭菌效率越高，经微波杀菌的馅料制品，其菌落总数和霉菌数量低，灭菌效果好，达到国家相关行业标准，对延长馅料制品的保质期非常有利。当然，除这些所被试过的样品外，还可以放一些我们日常所用的各种饮料、营养保健品、调味品等等…………

Technology of microwave sterilization because of the short time required, allowing a large degree of maintaining nutritional components of food and sterilization effect, you can make the food does not use preservative to extend shelf life.

Because of its advantages over traditional methods of food processing, technology of microwave sterilization recently more and more people's attention, be many applications in the food industry. Research and application of microwave sterilization in food has a lot of coverage. Kunming Polytechnic University Zhang Dr, people with microwave processing fresh milk 30 seconds, on can reached bacteria total of mass controlled standard; processing 90 seconds Hou is can will Escherichia coli, total kill, and save 3 days Hou still is not see bacteria growth, not only its nutrition components maintained does not variable, and by microwave processing role Hou, milk in the of fat ball diameter variable small, increased has milk fragrance, improve has products of stability, conducive to nutrition components of absorption. Dr Leung, who with winter melon and red bean fillings as specimens, studies on two kinds of stuffing of the best microwave sterilization technology, to address the stuffing products fresh bottlenecks and prolong filling products shelf life provide a theoretical basis. Experiment results show that the larger the microwave power and longer exposure time, sterilize more efficient, microwave sterilization of stuffing product, its low number of aerobic bacterial and mold, good sterilization effect, meet national industry standards, to extend the shelf life of stuffing products is very favourable.

Of course, in addition to those being tried outside the sample, you can also put some of our daily nutrition health products, beverages, spices and so on............
