Problems solved by technology

[0003] But seafood also has the following problems. For some people with poor stomach and intestines, the nutrients in seafood are not easy to absorb. Eating too much will cause abdominal distension, diarrhea and other problems. What's more, they will be allergic to seafood The problem, therefore, is that some people are not able to supplement nutrients through seafood

Embodiment 1

[0031] A method for double super extraction of marine nutrients, comprising the following steps:

[0032] (1) Prepare and clean the seafood to be extracted; among them, the seafood to be extracted includes shrimp, fish, crab, and seaweed.

[0033] (2) After freezing in liquid nitrogen, the seafood to be extracted is mixed with microcrystalline cellulose in a mass ratio of 58:1, and then the mixture is sent to an ultrafine pulverizer for pulverization to obtain seafood powder.

[0034] (3) Prepare 100 parts of the above-obtained seafood powder and 0.1 part of tert-butyl hydroquinone according to parts by mass. First, mix the seafood powder and 2mol / L hydrochloric acid solution at a material-to-liquid ratio of 1kg:3L. Stir evenly at 70°C to obtain slurry A; then mix tert-butyl hydroquinone and anhydrous ethanol solution at a material-to-liquid ratio of 0.1kg: 0.8L and stir evenly to obtain solution B; finally, mix slurry A with The speed of 5mL / min was added to the component B,...

Embodiment 2

[0040] A method for double super extraction of marine nutrients, comprising the following steps:

[0041] (1) Prepare and clean the seafood to be extracted; among them, the seafood to be extracted includes shrimp, fish, crab, and seaweed.

[0042] (2) After freezing in liquid nitrogen, the seafood to be extracted is mixed with microcrystalline cellulose in a mass ratio of 50:1, and then the mixture is sent to an ultrafine pulverizer for pulverization to obtain seafood powder.

[0043] (3) Prepare 100 parts of seafood powder and 0.05 part of tert-butyl hydroquinone according to parts by mass. First, mix the seafood powder and 1mol / L hydrochloric acid solution at a ratio of 1kg: 2L of material and liquid, and heat it at 60°C. Stir well to obtain slurry A; then mix tert-butyl hydroquinone and anhydrous ethanol solution at a material-to-liquid ratio of 0.05kg:0.5L and stir to obtain solution B; finally, slurry A is mixed at 4mL / min Add it to component B at a speed of 1000 %, and ...

Embodiment 3

[0048] A method for double super extraction of marine nutrients, comprising the following steps:

[0049] (1) Prepare and clean the seafood to be extracted; among them, the seafood to be extracted includes shrimp, fish, crab, and seaweed.

[0050] (2) After freezing in liquid nitrogen, the seafood to be extracted is mixed with microcrystalline cellulose in a mass ratio of 65:1, and then the mixture is sent to an ultrafine pulverizer for pulverization to obtain seafood powder.

[0051] (3) Prepare 100 parts of seafood powder and 0.2 part of tert-butyl hydroquinone according to mass parts. First, mix the seafood powder and 3 mol / L hydrochloric acid solution at a ratio of 1 kg: 4 L of liquid, and heat it at 75°C. Stir well to obtain slurry A; then mix tert-butyl hydroquinone and anhydrous ethanol solution at a material-to-liquid ratio of 0.2kg: 1L and stir evenly to obtain solution B; finally, mix slurry A with 6mL / min The speed is added to the component B, and the stirring is c...

Abstract

The invention relates to the technical field of biological extraction, in particular to a method for extracting marine nutrients by using both ultramicro grinding and supercritical carbon dioxide extraction. The method comprises the following steps: feeding a marine product to be extracted into an ultramicro grinder for smashing to obtain marine product powder; and mixing, in parts by mass, 100 parts of the marine product powder and 0.05-0.2 part of tert-butylhydroquinone, then feeding the obtained mixture into a supercritical carbon dioxide extraction kettle, and carrying out extraction at apressure of 30-40 MPa and a temperature of 40-60 DEG C for 2-4 h under the conditions that absolute ethyl alcohol with a flow of 5-8 L/h serves as a carrying agent and the flow of carbon dioxide is 400-500 L/h. According to the method, the manner of performing ultramicro grinding at first and performing supercritical carbon dioxide extraction next is adopted, so the obtained superfine powder is infull contact with a supercritical carbon dioxide fluid, good extraction effect is obtained, other impurities are not introduced, and the thermal degradation of an extract at high temperature is avoided. Meanwhile, the nutrient substances of the marine product are wrapped and protected by tert-butylhydroquinone before extraction, so the nutrient substances are prevented from deterioration and damage during extraction, and the integrity of the nutrient substances can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of biological extraction, in particular to a method for double super extraction of marine nutrients. Background technique [0002] Seafood, whether it is shrimp, fish, crab or seaweed, are rich in a variety of nutrients, including protein, unsaturated fatty acids, various trace elements and astaxanthin. The composition and content of amino acids in protein in seafood are suitable for human needs. Unsaturated fatty acids can reduce blood lipids, prevent the formation of blood clots, prevent atherosclerosis, coronary heart disease and strengthen the brain. Several trace elements such as iron, zinc and selenium It is easily necessary for the human body, and astaxanthin has excellent antioxidant effects. These marine nutrients have high nutritional value for the human body. People often choose to eat seafood to supplement these nutrients. [0003] However, seafood also has the following problems. For some peop...
