Example Embodiment

[0013] Example 1:

[0014] A biological deodorization technology of fish swim bladder, including raw material processing, preparation of deodorization liquid, fermentation deodorization, and removal of impurities, specifically including the following steps:

[0015] 1) Raw material processing: take the frozen fish bladder, thaw it, soak it in the salt water with a concentration of 1.2mg / L for 34 minutes, rinse with water, drain it, and set aside;

[0016] 2) Preparation of deodorant liquid: mix yeast and staphylococcus at a weight ratio of 0.5:1 to obtain a mixed strain, take the mixed strain and add water to prepare a mixed solution with a concentration of 1wt%, add sucrose and isooctyl stearate With ferulic acid, the addition amount of sucrose is 0.4wt%, and the mass ratio of sucrose: isooctyl stearate: ferulic acid is 1:0.002:0.004. Stir uniformly, culture for 7 hours under the conditions of pH 7 and temperature 40°C to obtain deodorant liquid. This deodorant liquid utilizes micr...

Abstract

The invention discloses a biological fishy-smell-removing technique of air bladders. The biological fishy-smell-removing technique comprises the following steps of treating raw materials, preparing fishy-smell-removing liquid, performing fermentation and fishy smell removal by using microzymes and staphylococcus mixed bacteria liquid, and removing impurities by using micromolecules and infectious microbes, which are generated during fishy smell removal through adsorption with beta-cyclodextrin and have peculiar smell. The biological fishy-smell-removing technique has the beneficial effects that the biological fishy-smell-removing technique enables the air bladders to be free from fishy smell, small in smell changes, good in integrity of the air bladders, and long in quality guarantee period under the condition of normal temperature. Microorganism bacteria are not remained, the air bladders can be good in mouth feel, the eating safety of the air bladder products is improved, the design is reasonable, the operation is convenient, and the condition that for a conventional technology, nitrite is used, so that carcinogen is generated and human health is damaged is avoided.

Description

technical field [0001] The invention relates to the field of aquatic product processing, in particular to a technology for biological deodorization of swim bladders. Background technique [0002] Swim bladder, commonly known as fish maw, is an important organ for adjusting the proportion of fish, and also plays a certain role in pressure sensing, vocalization and breathing. The nutritional value of fish fat is very high. It has the functions of nourishing blood, nourishing kidney, moistening lung and invigorating spleen and anti-inflammatory. The content is more than 80%, and the fat content is low, so it is an ideal high-protein and low-fat food. Fish maw is used, decocted in appropriate amount with Chinese angelica and red dates, and long-term consumption has certain curative effect on aplastic anemia. Fish maw stewed with the same amount of wine and water can treat spermatorrhea in men and leucorrhea in women. At present, the main destination of fish maw is to make hig...
