Trout roe production method

Abstract

The invention relates to a trout production technology, belongs to the field of fish breeding, and particularly relates to a trout roe production method. The method is characterized by comprising: after bred trout achieves sexual maturity, selecting trout parent fishes at a breeding season, wherein ovary of the selected trout parent fish develops to a V stage; adopting an extrusion method to extrude trout roes; carrying out immersion washing on the trout roes at a temperature of below 4 DEG C with an iodine-free salt solution with a concentration of 0.5-5%; carrying out pickling with an iodine-free salt solution with a proper concentration; draining water with gauze; and carrying out ultraviolet disinfection and packaging. The production method has the following beneficial effects that: the produced trout roe achieves a pollution-free food standard, and has characteristics of natural shape and high nutrition value; the operation method is simple and convenient, and complex equipment is not required; and the trout roe is produced so as to extend a trout industry chain, improve breeding benefits, avoid disadvantages of trout roe production through wild trout fishing, protect trout resources and maintain ecological balance.

Description

technical field [0001] The invention relates to a trout production technology, which belongs to the field of fish farming, in particular to a production method of trout roe. Background technique [0002] Caviar roe has high nutritional value and contains nutrients needed by the human body such as ovalbumin, globulin, ovomucoid and roe scale protein, and is delicious. Trout has few bone spurs, delicious meat, and high nutritional value. Trout roe has higher nutritional value. Its nutritional ingredients include: water 59.96%, protein 31.74%, fat 4.34%, ash 3.06%, and rich in vitamins and Minerals also contain essential amino acids that are easily digested and absorbed by the body. Driven by interests, people are fishing for mature trout that are about to spawn in natural waters to produce trout roe, and a large number of trout that have not yet spawned have been killed, resulting in a serious reduction in trout resources and serious damage to trout natural resources. threat...

Problems solved by technology

[0003] There are very few research reports on trout roe production technology at home and abroad. Only Liu Xuexun and Wang Xiulin from Beijing Institute of Fishery Science made a simple preliminary report on "Feminization of Rainbow Trout and Preliminary Research on Fish Roe Nutrition and Processing". Feminization of rainbow trout was induced, and a large number of mature female fish were obtained for caviar processing, and the nutritional composition of rainbow trout caviar was simply analyzed. There is no other research report on trout roe production technology
