Problems solved by technology

But there are also many disadvantages, such as the average food intake of animals, low nutritional level and bait utilization rate
A single L-amino acid or a mixture thereof has also been used as a food attractant additive for fish and shrimp, but its use is limited due to its high cost and high commodity price. Therefore, a food attractant with good food attractant effect and low cost has become a Problems to be solved and research and development hotspots

Embodiment 1

[0018] Embodiment 1: 50 kg of mussel meat and cod 30 kg are mixed according to the weight ratio of feed to water=1:5, the pH is adjusted to 9.0 and the homogenate is carried out for alkali extraction, and some impurities are removed by sieving; papain (600,000 IU / G) is added 1.2 grams, adjust the appropriate pH to 7.5, after 4 hours of constant temperature enzymolysis at 65°C in a hot and cold cylinder, heat up to 90°C and keep for 10 minutes to inactivate the enzyme, then lower the temperature back to 45°C, and then add aminopeptidase P Enzymolysis with carboxypeptidase for 5 hours to eliminate bitterness; after that, add ethoxyquinoline accounting for 0.8% by weight of fresh animal protein source raw materials, filter to obtain hydrolyzate, then concentrate, and spray dry in a high-speed centrifugal spray dryer That is, the desired dry powder of animal protein enzymatic hydrolyzate can be obtained; the nozzle speed of the spray drying is 18000r / min, the inlet temperature is 1...

Embodiment 2

[0020] Embodiment 2: 60 kg of medlar and 10 kg of squid meat are mixed according to the weight ratio of feed to water=1: 4.5, the pH is adjusted to 9.0 and homogenized for alkali extraction, and some impurities are removed by sieving; add trypsin (6000IU / G) 1.0 Gram and papain (700,000 IU / G) 0.8g, adjust the appropriate pH 7.0, after 3 hours of constant temperature enzymolysis at 60°C in a hot and cold cylinder, heat up to 88°C for 15 minutes to inactivate the enzyme, then Cool down to 60°C, add aminopeptidase P for 5 hours to eliminate bitterness; add ethoxyquinoline accounting for 1.5% by weight of fresh animal protein source raw materials, filter to obtain hydrolyzate, and then concentrate and centrifuge at high speed Spray drying in a spray dryer can obtain the desired dry powder of animal protein enzymatic hydrolyzate; the nozzle speed of the spray drying is 16000r / min, the inlet temperature is 170°C, and the outlet temperature is 950°C. With the obtained animal protein h...

Embodiment 3

[0022] Embodiment three: 30kg squid meat and cod 30kg are mixed according to feed-water weight ratio=1: 5, adjust pH9.0 and homogenize carry out alkali extraction, sieve to remove part impurity; Add papain (600,000 IU / G) 1.2 gram, adjust the appropriate pH to 7.5, and after 4 hours of constant temperature enzymolysis at 65°C in a hot and cold cylinder, heat up to 90°C and keep for 10 minutes to inactivate the enzyme, then lower the temperature back to 45°C, and then add aminopeptidase P and Carboxypeptidase enzymolysis for 5 hours to eliminate bitterness; after completion, add ethoxyquinoline accounting for 3% of the weight of fresh animal protein source raw materials, filter to obtain the hydrolyzate, then concentrate, and spray dry in a high-speed centrifugal spray dryer. The required dry powder of animal protein enzymatic hydrolyzate is obtained; the nozzle speed of the spray drying is 18000r / min, the inlet temperature is 180°C, and the outlet temperature is 100°C. With the...

Abstract

The invention pertains a kind of phagostimulant to rockfishes and other fishes, and its produce way. Materials by weight: animal protease 70-85%, nucleotide 2-10%, sulphocompound 0.4-3%, complex aminoacid 5-15%, betaine 2-20%, pigment 0.5-5%, oxidation preventive 0.1-0.5%. Production way: add animal protease after enzymolysis in oxidation preventive of 0.5-3% of fresh animal protease by weight; add by rate nucleotide, sulphocompound, complex aminoacid, betaine, pigment, oxidation preventive, mix and dry them, then the phagostimulant is made over. This phagostimulant can absorb sober of water animal effectually, promote growing, increase the ability of defeat disease, and increase the rate of living.

Description

technical field [0001] The invention relates to a high-efficiency food attractant for aquaculture animals such as grouper and a preparation method thereof. technical background [0002] Grouper, a valuable economic fish in aquaculture, has delicious meat and high economic value, especially in Southeast Asia, Japan, Hong Kong and Macao markets, where it is expensive and is a high-end seafood. As people's demand for fresh and live seafood is increasing day by day, the market is increasingly in short supply. Many countries at home and abroad are actively carrying out artificial breeding of seawater economic animals such as grouper. The popularity of breeding has increased the demand for seedlings, but the number of natural seedlings is limited. The artificial breeding of seawater economic animals such as grouper and adult fish farming is a high-value technology industry with obvious economic benefits and has broad market prospects. . [0003] Food attractant belongs to a kin...
