Description

一种蟹糊的制备方法A kind of preparation method of crab paste

技术领域 technical field

本发明属于水产品的加工技术领域,具体涉及一种蟹糊的制备方法,即在制备步骤中添加月桂酸单甘酯和/或精油。The invention belongs to the technical field of aquatic product processing, and in particular relates to a preparation method of crab paste, that is, adding monoglyceride laurate and/or essential oil in the preparation step.

背景技术 Background technique

蟹糊是传统的腌制生食水产品,系由新鲜海蟹拆肉糟渍而成,其味道鲜美,营养丰富,在沿海省及毗邻省、市有着广阔市场。但由于生产中无热加工过程,而且食用前无需热处理,直接食用,属食用安全高风险食品。传统的蟹糊加工步骤包括选料、清洗、清理、破碎、配料调味、包装、冷藏贮藏等工序,产品中食盐氯化钠含量较高。比如,GB10136-88《蟹糊卫生标准》规定蟹糊的盐分≥15%,但产品食盐含量过高,因其高钠,不适用于患有高血压、心血管疾病及肾衰等的病人食用。为了迎合消费者的“鲜淡风味”,市场上兴起了腌制蟹糊冷链式产销过程,使盐分都降至7%左右。而在低NaCl含量情况下微生物指标合格率低。为了控制微生物指标的合格率,专利ZL200710070672.X“蟹糊的工厂化加工与杀菌方法”中就采用了辐照灭菌的方式来减少微生物。但蟹糊产品中的脂肪经高剂量辐射后,因氧化反应产生的自由基及其衍生物会促进脂肪的氧化而使其发生酸败变性,尤其是不饱和脂肪酸容易氧化,出现脱羧、氢化、脱氨等作用,会导致脂肪的消化吸收率降低。因此,如何开发出一种既能降低盐的浓度,又能够有效的控制蟹糊产品中的细菌含量,且又不会影响其“鲜淡风味”的加工方式和绿色灭菌方法就成为一个长期没有解决的问题。Crab paste is a traditional marinated raw food aquatic product, which is made from fresh sea crabs. It is delicious and nutritious. It has a broad market in coastal provinces and adjacent provinces and cities. However, since there is no heat processing process in the production, and no heat treatment is required before eating, it can be eaten directly, which is a high-risk food for food safety. The traditional crab paste processing steps include material selection, cleaning, cleaning, crushing, ingredients seasoning, packaging, refrigerated storage and other processes, and the content of salt and sodium chloride in the product is relatively high. For example, GB10136-88 "Hygienic Standards for Crab Paste" stipulates that the salt content of crab paste is ≥15%, but the salt content of the product is too high. Because of its high sodium, it is not suitable for patients with high blood pressure, cardiovascular disease and renal failure. . In order to cater to the "fresh and light flavor" of consumers, a cold chain production and sales process of marinated crab paste has emerged in the market, reducing the salt content to about 7%. And in the case of low NaCl content, the pass rate of microbial indicators is low. In order to control the pass rate of microbial indicators, the patent ZL200710070672.X "Industrial Processing and Sterilization Method of Crab Paste" uses radiation sterilization to reduce microorganisms. However, after the fat in the crab paste product is irradiated at a high dose, the free radicals and its derivatives produced by the oxidation reaction will promote the oxidation of the fat and cause it to become rancid and denatured, especially unsaturated fatty acids are easy to oxidize, and decarboxylation, hydrogenation, and decarboxylation occur. Ammonia and other effects will lead to a decrease in the digestion and absorption rate of fat. Therefore, how to develop a processing method and a green sterilization method that can reduce the concentration of salt and effectively control the bacterial content in crab paste products without affecting its "fresh and light flavor" has become a long-term problem. There is no problem to solve.
