Effect test

Embodiment 1

[0023] The protein waste liquid of an aquatic product processing factory adopts double-effect concentration to have a crude protein content of 15% and a water content of 89%. Add 25 liters of Lactobacillus fermentation broth per ton of concentrated liquid (bacteria concentration 3.5×10 7 cfu / ml), add 20 kg of sucrose, and make secondary fermentation at 35°C to preserve freshness. The shelf life reaches 30 days, and the pH value of the mixture drops from 7.8 to 4.0. Starworms grow 50% faster.

Embodiment 2

[0025] Spirulina mud will stink and deteriorate in 4 hours when the temperature exceeds 28°C, but its water content exceeds 95%. The cost of spray drying is 8,000 yuan / ton, and Lactobacillus casei is added per ton of algae mud 100 liters of Lactobacillus fermentum fermentation broth (bacteria concentration 1×10 8 cfu / ml), 400 liters of clean water, and the shelf life can reach 7 days after mixing evenly. It is gradually used to feed mudskippers. Under the same density, the breeding cycle of mudskippers is 30% shorter than that of conventional farming.

Embodiment 3

[0027] Potato protein puree will stink and deteriorate in 2 hours when the temperature exceeds 30°C, but its water content exceeds 85%. The cost of spray drying is 7,000 yuan / ton, and it is added per ton of potato protein puree Lactobacillus, Lactococcus, Lactobacillus acidophilus fermentation broth 50 liters (bacteria concentration 1×10 8 cfu / ml), 300 liters of clean water, and the shelf life can reach 1 year after mixing evenly. It is gradually used to feed mudskippers. Under the same density, the breeding cycle of mudskippers is 20% shorter than that of conventional farming.

Abstract

The invention relates to the technical field of storage of aquatic feeds, and particularly relates to a processing anti-corrosion method of the aquatic feeds. The processing anti-corrosion method of the aquatic feed is characterized by taking raw materials, such as fish paste, amino acid consecrated liquor, potato protein paste, yeast paste, spirulina paste, and the like which are rich in proteins and amino acids as main components, carrying out corrosion prevention and preservation by directly mixing lactic acid bacteria fermentation liquor with high-protein substances and enabling the high-protein substances to become high-quality feeds or baits which can be used for aquaculture. Compared with the traditional method, the processing anti-corrosion method has the advantages of reducing the environment pollution and the aquaculture cost, increasing the culture benefit and enhancing the quality of cultured animals.

Description

technical field [0001] The invention relates to the technical field of storing aquatic feed, in particular to a method for processing and preserving aquatic feed. Background technique [0002] The method relates to a method for processing and preserving aquatic feed. The aquatic feed is mainly composed of raw materials rich in protein and amino acids, such as fish paste, amino acid concentrate, potato protein paste, yeast paste, and spirulina paste. Concentrated liquid or paste with high water content exists in the form of paste, which is easy to rot and stink under normal conditions. It will not only pollute the environment, but also increase the environmental protection cost of the enterprise. If it is dried, the cost will be extremely high. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a method for processing and antisepsis of aquatic feed that solves the pollution problem of these high-water-containin...
