Preparation method of broad bean aqueous extract feed, product and application of broad bean aqueous extract feed in embrittlement of fish muscles

Abstract

The invention relates to a preparation method of broad bean aqueous extract feed, a product and application of the broad bean aqueous extract feed in embrittlement of fish muscles. The method comprises the following steps: preparation of broad bean powder, preparation of a saturated calcium hydroxide solution, preparation of 4M hydrochloric acid, extraction of a broad bean aqueous extract, preparation of broad bean aqueous extract powder, preparation of compound feed powder, preparation of a mixture of a compound feed and the broad bean aqueous extract, and preparation of a broad bean aqueousextract feed. The broad bean extract feed extracted by the method is used for fishes, can significantly improve the muscle hardness, chewiness and cohesiveness of the fishes and promote the growth performance of the fishes, and is an innovative application in fish culture.

Description

technical field [0001] The invention relates to the technical field of aquatic product functional feed, in particular to a preparation method and product of broad bean water extract feed and its application in embrittlement of fish muscles. Background technique [0002] Broad bean is a kind of leguminous plant, which has developed rapidly in food processing in recent years. Broad bean is a crop rich in protein, minerals and vitamins, and is one of the high-quality sources of nutrition. However, the anti-nutritional factors in broad beans will reduce the rational utilization of nutrients in broad beans. Many existing treatment methods have been applied to the processing and treatment of broad beans, among which several methods such as shelling, soaking, rinsing and germination can reduce the content of anti-nutritional factors. [0003] Studies have shown that broad beans as a single food source significantly improve fish muscle texture, especially with "crisp" properties. ...

AI Technical Summary

Problems solved by technology

It has greatly increased the economic benefits of grass carp farming, but studies have also shown that broad beans have certain defects while improving muscle characteristics: (1) broad beans lack some amino acids or have insufficient content of some amino acids and anti-nutritional factors, resulting in low growth rates of fish; (2) Broad beans contain some anti-nutritional ingredients such as protease and amylase inhibitors, broad bean pyrimidine nucleoside, congeny broad bean pyrimidine nucleoside, phytate, etc., which may cause intestinal inflammation; (3) broad bean can cause hemolysis and oxidative damage, etc. question

However, the growth rate of fish fed with broad bean powder brittle compound feed is generally low, and it still contains anti-nutritional factors that have adverse effects on healthy growth. Therefore, it cannot meet the requirements of rapid growth while brittle fish muscles
