[0003] The nutritional value of Botrytis elongatum is extremely high, especially the protein content in it is very considerable. How to extract the nutrients in Botrytis elongatus has always been the focus of research. The existing preparation method of Botrytis elongatus extract is The process is time-consuming and labor-intensive, which reduces work efficiency, and various reagents are used for extraction, which is costly and incomplete, which easily causes waste of resources. Grape fern extract has a wide range of applications, and it also has applications in the production of ornamental fish feed. , the existing ornamental fish feed is easy to scatter and expand when entering water, and has low nutritional value, which reduces the quality of fish feed

Abstract

The invention discloses a preparation method of a caulerpa lentillifera extract and an application of the caulerpa lentillifera extract in an aquarium fish formula feed. The preparation method comprises the following steps: step 1, cleaning and soaking; step 2, high-temperature drying; step 3, crushing and sieving; step 4, primary extraction; step 5, centrifugal layering; step 6, separating and storing; step 7, secondary extraction; step 8, weighing the raw materials; step 9, mixing and homogenizing; step 10, spray drying; step 11, puffing and granulating; and step 12, packing and warehousing. Permeation between a solvent and the extract is increased through cavitation, shearing and thermal effects of ultrasonic waves, so that the extraction efficiency is favorably improved, secondary extraction is carried out on extracted residues, thorough extraction is favorably realized, resource waste is reduced, the caulerpa lentillifera extract is used as a formula for preparing the fish feed, the feed is beneficial to improving the immune function of fishes, improves the survival rate, effectively prevents fat oxidation in the feed, and promotes wound healing of the fishes.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a preparation method of a grape fern extract and its application in formula feed for ornamental fish. Background technique [0002] Botrytis elongatus, belonging to the family Chlorophyta Pteridaceae, is mainly distributed in Japan, Indonesia, Vietnam, etc., and has been introduced into my country for cultivation in large quantities in recent years. Its appearance is crystal clear and plump like a grape, so it is called sea grape. It is a kind of nutrient-rich edible green algae, which contains a variety of nutrients. It has anti-cancer, anti-tumor, anti-oxidation, improve immunity, activate brain cells, purify blood, Beauty and other effects, 80% of the long-stem grape fern algae are composed of seaweed polysaccharides, collagen and dietary fiber. Of the 16 amino acids detected in its body, 11 are essential amino acids for the human body, and 7 amino acids cannot be synt...
