Effect and Wholesomeness of Electron Beam Irradiation to Food.

随着生活方式的急剧变化和变化，日本人的饮食方式也发生了变化。此外，人们越来越关注自己的健康。另一方面，他们对美食或由复杂食物材料制成的食物感兴趣。然而，它们主要是由异质原材料或半干材料，似乎满足消费者的需求。同时，消费者对含有防腐剂等食品添加剂的食品有拒绝态度。为了满足消费者的需求，食品生产企业似乎也抑制了食品添加剂的使用。在这种氛围下，食品腐败、变性、食物中毒的风险可能会增加，从食品安全和经济的角度来看，这是不容忽视的。为了将这些风险降至最低，早期消毒非常重要。本研究旨在重新评估电子束辐照食品，特别是海洋材料，曾经引起人们的兴趣，但很快， ...更多信息 由于电子束的穿透性较低，我们通过比较传统的消毒技术，包括γ射线辐照，评价了电子束辐照对孢子形成菌、大块食品材料如姜黄条的消毒效果。用电子束辐照人工感染大肠杆菌的生产用水，得到了一些有趣的结果。大肠杆菌、短小芽孢杆菌、嗜热脂肪芽孢杆菌等菌株的孢子萌发率均高于未辐照的孢子。揭示其机制的研究正在进行中。用整个姜黄指对大块材料的消毒效率的研究表明，从实用的角度来看，电子束辐照足够有帮助。作为初步研究，我们检查了辐照禽肉和鸡蛋白色蛋白的营养保健。在相当高剂量的两次辐照中均未观察到营养损害。少

With the dramatic changes and variation of life styles, eating styles of Japanese people have also changed. In addition, people are getting more concerned about their health. On the other hand, they show interest in gourmet, or foods made of complex food materials. However, they are largely made up of heterogenous raw or semi-dried materials which seem to meet consumer's demand. At the same time, consumers have attitude to refuse foods containing food additives such as preservatives. In response to consumer's demand, manufacturers seem to have suppressed the use of food additives, either.Under such atmosphere, it may increase risks of food spoilage, denaturation, and food poisoning, which we should not overlook from the standpoints of food safety and economy. To make such risks minimum, disinfection at the early stages is important. The present research was undertaken to reevaluate the electron beams irradiation to food especially marine materials that once attracted interest but soon … More was outcast because of low penetrability of the beams.We evaluated effect of electron beams irradiation on the disinfection of spore-forming bacteria, bulky food material such as turmeric fingers by comparing conventional disinfection techniques including gamma-ray irradiation. We obtained some interesting results from the electron beams irradiated manufacturing water which was intentionally infected with E. coli, acillus pumlius, Bacillus stearothermophilus and so on. An interesting result was that germination rate of irradiated spores was higher than that of non-irradiated spores. Study to reveal its mechanism is now under way. Studies on the disinfection efficiency of bulky material using whole turmeric fingers showed that electron beams irradiation helpful enough from practical viewpoint. As a preliminary study, we examined the nutritional wholesomeness of irradiated poultry meat and egg white protein. No nutritional damage was observed in both irradiations at considerably high doses.
