利用原子射线保藏食品是一种新技术,它可以减少食品的损耗率,增加供应量,延长供应期)从而能更好地贯彻执行“发展经济,保障供给”的方针。但是用辐射方法保藏食品也不一定能适应于所有的品种,要有选择性的应用,开展这项研究工作对当前和今后的国民经济的发展将起着重要作用。天津市是地处沿海的大城市,水产品的供应及保鲜工作仍存在种种实际问题。据不完全的统计,每年腐败变质的水产品,数量相当可观,造成了巨大的损失。为了搞好水产品(以鱼为主)的市场供应工作,在市科技局及水产局、公司各级领导的支持 The preservation of food by atomic radiation is a new technology that can reduce the loss rate of food, increase the supply and extend the supply period, so as to better implement the principle of “developing economy and guaranteeing supply”. However, the method of preserving food by radiation is not necessarily applicable to all varieties. Therefore, it is necessary to carry out this research work which will play an important role in the current and future development of the national economy. Tianjin is a large city located in the coastal areas. There are still practical problems in the supply and preservation of aquatic products. According to incomplete statistics, the annual amount of spoilage aquatic products is considerable, causing huge losses. In order to do a good job market supply of aquatic products (mainly fish), the municipal Science and Technology Bureau and the Bureau of Fisheries, the leadership of the company at all levels of support
