Embodiment 1

[0039] 1. Take 1 tons of fish meal wastewater and use the oil -proof equipment with a treatment volume of 1 ton / hour to remove the floating oil and suspension in the wastewater.The oil -water separator with a speed of 7300R / min and a processing volume of 2 tons / hour removes other oil and sediments in the wastewater.

[0040] 2. Puritated vine -meal wastewater after the above methods, and use the nattial filter membrane with a relative molecular mass of 1kd to remove the purification of small molecular impurities, and condense into a concentrated solution with a mass percentage of 5%.

[0041] 3. Use spray to dry and dry quickly. The air outlet temperature is 90 ° C above the above concentrated liquid. The air inlet temperature is 180 ° C. The spray is dry and the spray is over. The finished fish protein powder is obtained.

[0042] 4. Put the fish protein concentrated liquid of the step 2 into the reactor. Use papaya protein enzymes to disintegrate. The enzymatic disintegration co...

Abstract

The invention discloses a method for producing fish protein and fish protein peptide and belongs to the technical field of biology. The method comprises the following steps: (1) oil removing equipment isolation technology in coordination with an oil-water separating unit isolation technology is adopted to remove solid impurities and fats and oils in minced fillet waste water; (2) a membrane separation technology is adopted to separate, purify and concentrate fish protein solution; (3) fish protein powder finished product is obtained after the fish protein solution is dried; (4) an enzymic method is adopted to dispose fish protein solution obtained through step (2), so as to prepare fish protein peptide; (5) fish protein peptide powder finished product is obtained after the fish protein peptide solution is dried. According to the method, the minced fillet waste water is adopted to change waste into valuable; an isolation technology system which is integrated by coordination with the oil removing equipment isolation technology, the oil-water separating unit isolation technology with the membrane separation technology is established; the problems that membrane pollution is serious, the service life is short in a conventional minced fillet waster water research and development technology are solved; the production cost is reduced; the producing fish protein products has high protein content; the safety of fish protein peptide product is high; the relative molecular weight is low averagely.

Description

Technical field [0001] The present invention involves a method of producing fish protein and a method of producing fish protein peptides, which belongs to the field of biotechnology. Background technique [0002] Hermi products industry is one of the main pillar industries of my country's aquatic product processing industry, and the industry development cycle is in the stage of industrial growth.However, a large amount of wastewater is generated during the production process of cord products, increasing the production cost and environmental protection costs of enterprises, and restricting the development of the industry.Modern scientific research shows that cotton wastewater is mainly composed of fish protein, oil, insoluble floats, and other small molecular impurities. Fish protein and fish protein peptide products produced by rodum wastewater as raw materials can be widely used in food.The pharmaceutical industry and cosmetics industry. [0003] At present, the method of produc...
