Problems solved by technology

[0002] A large amount of sea cucumber cooking liquid is produced during sea cucumber processing, and the usual treatment method is to discharge it directly as waste. According to preliminary statistics, nearly 10,000 tons of fresh and dried sea cucumbers are processed annually to produce nearly 10,000 tons of sea cucumber cooking liquid. The surrounding natural environment brings pollution and the regeneration resources of sea cucumbers cause waste

Embodiment 1

[0031] Collect 1000kg of cooking liquid produced in sea cucumber processing, and circulate it into a vacuum thermal diaphragm low-temperature concentrator, control the vacuum degree of 1.0Mpa, heat at 40°C, and concentrate it into 600kg of sea cucumber boiling liquid concentrate after 2 hours.

[0032] Use a material pump to transport to a 1000L vacuum bioreactor, adjust the pH to 7, and heat to 40°C with steam. Add 120g of compound protease (protamex produced by Novozymes Functional Food Industry, Denmark); 180g of 1398 neutral protease; 120g of 1203 lipase; 240g of Vc, then seal it, vacuumize 100Pa and stir for 6 hours, and use a material pump to input 100 mesh to 300 Objective Duplex filter to separate the impurities in the liquid to obtain 600kg compound enzymolysis solution. Then use 0.1 μPa vacuum suction to the 1000L enzyme modification reaction kettle, adjust the pH value to 7, control the temperature at 40°C, add 180g of compound flavor protease (Flarouzyme produced b...

Embodiment 2

[0037] The difference from Example 1 is that: 1000 kg of sea cucumber boiling liquid was concentrated in a vacuum thermal diaphragm cryogenic concentrator at a vacuum degree of 4.0 MPa and a concentration temperature of 60° C. for 2 hours to concentrate 500 kg of sea cucumber boiling liquid, and the concentration rate was 50%;

[0038] Use a 1000L vacuum bioreactor to adjust the pH to 7, the temperature is 50°C, and the vacuum degree is 200Pa. Add 200g of compound protease; 100g of 1398 neutral protease; 150g of 1203 fat; 100g of Vc, and stir for 8 hours. Separation with a 100-mesh to 300-mesh duplex filter to obtain 500kg of compound enzymolysis solution, modify the reaction kettle with 1000L biological enzymes, adjust the pH value to 7, the temperature is 50°C, and the vacuum degree is 300Pa. Add 400g of compound flavor protease; 50g of phospholipase A; stir the enzyme modification reaction for 4 hours, and inactivate the enzyme at 140°C for 30min.

[0039] Use 2-1um, 0.4-0....

Abstract

The invention relates to deep processing of sea cucumbers, in particular to a method for preparing sea cucumber collagen small peptide freeze drying powder extracted from sea cucumber decoction liquor. The method adopts the sea cucumber decoction liquor as the raw material and comprises the steps of A. obtaining the sea cucumber decoction liquor; B. enzymatic hydrolysis; C. purification of sea cucumber collagen small peptide; and D. freeze-drying, drying and product packaging. The method can increase the processing rate and nutritional value of sea cucumbers, and by adopting FD space biological freezing and drying technology, the activity, oxidation resistance, re-polymerization resistance and moisture binding resistance of the sea cucumber collagen small peptide can be kept, and the sea cucumber collagen small peptide can be stored easily due to less moisture.

Description

technical field [0001] The invention relates to deep processing of sea cucumbers, in particular to a method for extracting freeze-dried powder of small collagen peptides of sea cucumbers by using discarded sea cucumber boiling liquid. Background technique [0002] A large amount of sea cucumber cooking liquid is produced during sea cucumber processing, and the usual treatment method is to discharge it directly as waste. According to preliminary statistics, nearly 10,000 tons of fresh and dried sea cucumbers are processed each year, and nearly 10,000 tons of sea cucumber cooking liquid is produced. The surrounding natural environment brings pollution and the regeneration resources of sea cucumbers cause waste. According to research, sea cucumber cooking liquid is rich in sea cucumber saponins, sea cucumber mucopolysaccharides, sea cucumber collagen and dipotassium salt. It is the purpose of the present invention to collect the sea cucumber boiling liquid and use the core tec...
