Problems solved by technology

Due to poor bonding, the feed is easy to collapse after entering the water, without a certain shape, which hinders the feeding of aquatic animals with the palatability of the feed shape; moreover, after the feed is dissolved in water, nutrients are wasted and water quality is polluted , and even lead to large-scale disease

Embodiment 1

[0019] Embodiment 1: A plant-based adhesive for aquatic feed and its production method, characterized in that: it consists of the following raw materials in proportion by weight: 13 parts of kelp extract, 3 parts of tangerine peel extract, 2 parts of compound Chinese herbal medicine, α- 3 parts of starch, 6 parts of bentonite.

[0020] The preparation method of the kelp extract is as follows:

[0021] (1) Grinding: Put the dried kelp into a feed grinder to grind, and pass through a 90-mesh sieve;

[0022] (2) Digestion: Accurately weigh the crushed kelp, add 1.0% sodium hydroxide based on the weight of the kelp, and stir evenly;

[0023] (3) Soaking: add 1.3 times the weight of kelp to soak in hot water at 80°C for 3 hours, filter to obtain the filtrate;

[0024] (4) Adjust the pH: adjust the pH to 6.8 with citric acid in the filtrate obtained in step (3), keep it for 1.5 hours, and dry it in vacuum to obtain the kelp extract.

[0025] The preparation method of the tangerin...

Abstract

The invention discloses an aquatic feed vegetable adhesive and a preparation method thereof. The aquatic feed vegetable adhesive is characterized by being prepared from the following raw materials in parts by weight: 10-15 parts of a kelp extract, 2-4 parts of a dried tangerine peel extract, 1-3 parts of a compound Chinese herbal medicine, 2-4 parts of alpha-starch and 5-8 parts of bentonite. The adhesive has the characteristics of simple process, low cost and appropriate adhesiveness, and can increase nutritional ingredients of in a bait material, improve the palatability of a feed, promote in vivo nutrition metabolism and improve the anti-stress capability of fishes.

Description

technical field [0001] The invention relates to a plant-based adhesive for aquatic feed and a preparation method thereof, belonging to the technical field of feed additives. Background technique [0002] Since aquatic animals live in water, they have higher requirements on the palatability and cohesiveness of feed, and the size, hardness, floating and sinking of feed particles directly affect the feeding of aquatic animals. This brings certain difficulties to the production of aquatic feed. If the aquatic feed is not well bonded, even if the feed is the most nutritious, it is meaningless to add more palatable food attractants, amino acids, vitamins, mineral salts, etc. Due to poor bonding, the feed is easy to collapse after entering the water, without a certain shape, which hinders the feeding of aquatic animals with the palatability of the feed shape; moreover, after the feed is dissolved in water, nutrients are wasted and water quality is polluted , and even lead to wide...
