Problems solved by technology

At present, the traditional processing and eating methods waste the nutritional resources of jellyfish, which are only limited to the processing of jellyfish skin and jellyfish head, and almost all jellyfish eggs with rich nutrition and high medicinal value are abandoned.

Embodiment 1

[0029] Take jellyfish caught in autumn and peel off 60kg of jellyfish eggs, add 1000g of pure water to each quick-freezing tray on average, and send them to the quick-freezing warehouse for freezing. The quick-freezing temperature is controlled at -35°C and the freezing rate is 2.0mm / h. Take it out and seal it in a compound plastic bag, pack 3 bags of 6kg in each incubator, and store in a freezer at -18°C in a total of 20 boxes of 120kg. Take it out during production and put it into a 50kg stainless steel barrel, put 5 bags in each barrel, add 10kg of pure water to thaw for 2 hours, and when the jellyfish roe jelly is completely thawed, obtain 240kg of jellyfish ovum water.

[0030] Add 240kg of jellyfish egg water into a 500L vacuum enzymolysis reaction kettle, start the agitator, and control the stirring speed at 30r / min; use steam to heat the raw material to a temperature of 40°C; add 180g of vitamin C (3g / kg) of jellyfish egg body weight to adjust The pH value is 7; 240g (...

Embodiment 2

[0035] Different from Example 1, the process of obtaining DHA jellyfish egg polypeptide freeze-dried powder is as follows:

[0036] Take 60kg of jellyfish eggs stripped from jellyfish caught in autumn. Use fresh jellyfish eggs for direct enzymatic hydrolysis. Add 60kg of jellyfish ovum to 120kg of pure water, make 180kg of jellyfish ovum slurry through a colloid mill, put it into a vacuum enzymolysis reactor, adjust the pH to 7, heat at 60°C, and stir at 60r / min. Add AS1398 neutral protease 120g (2g / kg) per kilogram of fresh jellyfish egg weight; EC.3.1.4 phosphodiester hydrolase 120g (2g / kg); lactic acid bacteria 120g (2g / kg); / kg). The vacuum degree is 200Pa, and the enzyme reaction is carried out for 12 hours to obtain 180kg of jellyfish egg compound enzymolysis solution.

[0037] 180kg of jellyfish egg compound enzymatic hydrolysis solution was input into the vacuum enzyme modification reactor with a feeding pump, the temperature was 60°C, and the stirring speed was 90r...

Abstract

The invention relates to the deep processing of jellyfish, in particular to a method for manufacturing DHA jellyfish egg polypeptide freeze-dried powder by adopting jellyfish eggs and includes the following steps: a. obtaining jellyfish eggs; b. biological composite enzymolysis; c. biological enzymatic modification; d. jellyfish egg polypeptide purification; e. low temperature concentration; f. vacuum complex formulation; g. vacuuming freeze-dried powder. The invention has the positive effects that the jellyfish egg polypeptide is formed by making use of the abandoned jellyfish egg in the jellyfish processing and adopting the technologies of composite enzymolysis and enzymatic modification; the invention refines the fish oil, lecithin, Vitamin E, taurine and chitosan through the super-membrane purification and vacuum complex formulation, vacuums and freeze-dries the jellyfish egg polypeptide freeze-dried powder rich in DHA as well as prepares the DHA jellyfish egg polypeptide freeze-dried powder with inclusion, oxidation resistance, anti-complex polymerization and edible trophism, which can alleviate physical fatigue, have the function of vasodilation, reduce the blood pressure and blood fat and enhance the immunity.

Description

technical field [0001] The invention relates to deep processing of jellyfish, in particular to a method for using jellyfish ovum and DHA as lyophilized nutritional polypeptide powder. Background technique [0002] The nutritional value and medicinal value of jellyfish are very high, and the therapeutic effect of jellyfish is recorded in "Compendium of Materia Medica". According to the research, in recent years, the nutritional composition, pharmacological analysis and clinical test results of jellyfish have shown that jellyfish, as a medicine, "has the functions of relaxing blood vessels, lowering blood pressure, dispelling accumulation and dispersing qi, moistening intestines and eliminating accumulation, reducing inflammation and asthma, removing ulcers, Anti-fatigue effect". Jellyfish is rich in protein, amino acid, unsaturated fatty acid, inorganic salt, calcium, iron, zinc, vitamins and other nutrients. At present, the traditional processing and eating methods waste t...
