Description
Technical field
The present invention relates to the processing method of krill protein powder, especially a kind of method for preparing low fluorine krill aminosal powder.
Background technology
Krill is that a kind of reserves are huge, has the protein resource of potential value of exploiting and utilizing.Its appreciable reserves are hundred million tons of 4-6.Krill protein content height, protein content accounts for 64%(in dry in the muscle), its amino acid content is abundant, and 8 kinds of essential amino acid proportions 45.28% are a kind of high-quality marine animal property protein.Because krill is in the marine eco-environment of high latitude low temperature, in its crust transformation process, the excessive calcium ions and magnesium ions of fluorine ion in crust is combined in the absorption seawater, a large amount of fluorine is deposited among the crust, after the dried up death of krill under the effect of shrimp body endoenzyme, fluorine ion penetrates among the muscle, makes the fluorine content in the krill muscle higher.Result of study shows krill fluorine content distribution: crust mean value 4028 μ g/g, and head (connecting feeler) mean value is 2724 μ g/g, and uropodium mean value is 2828 μ g/g, and muscle mean value is 226 μ g/g, the ensemble average value is 1232 μ g/g(butts).Because the fluorine content of krill is far above China GB2762-2005 food contaminant fluorine value of limiting the quantity of, fish (fresh water) can not eat krill as other marine products shrimp is direct less than the regulation of 2.0mg/kg.Because fluorine content is higher than the edible scope, make the essential method by the biotechnology defluorinate of utilization of krill, the albumen of krill is changed into water-solubility protein, remove the fluorine ion in the aqueous solution, and then be dried into protein powder, become edible albumen.Because fluorine ion mainly is present in the trade effluent, carry out ion exchange with calcium chloride, be to derive from sewage disposal to go the fluorine method with aluminium electrode enrichment fluorine ion etc., can cause protein powder salt content height among being applied to food production, problems such as ash, content of beary metal exceed standard do not meet requirement and the standard of food production.
Summary of the invention
The problem that the present invention need solve provides a kind of food production standard that meets, and production technology is simple and safe, the preparation method of the krill protein powder of the low fluorine content of suitable large-scale production.
Technical scheme of the present invention is the full shrimp of fresh krill or shrimp to be rubbed the water that adds 2 times of full shrimp or shrimp weight mix, be warmed to 100～105 ℃, stirred 30 minutes, after cooling to 45 ℃ ± 2 ℃ protease hydrolyzed temperature, add 0.2～0.5% trypsase or papain, constant temperature enzymolysis 2 hours is warmed up to 90～95 ℃ again and keeps 20 minutes enzymes that go out, and filters and removes shrimp shell and impurity; Feed liquid is crossed NF membrane dewaters to protein content 20% ± 2%, the cocoanut active charcoal that adds protein content 20% feed liquid weight 4%, being heated to 70～80 ℃ stirred 15～30 minutes, filter and remove cocoanut active charcoal, the deionized water that adds 5 to 7 times of material liquid volumes, the dilution hydrolyzed protein liquid, dewater with NF membrane again, until protein in feed liquid content 〉=20%, the cocoanut active charcoal that adds protein content 20% feed liquid weight 4% again is heated to 70～80 ℃ and stirred 15～30 minutes, filters and removes cocoanut active charcoal, vacuum is concentrated into protein concentration 35%-40% again, is made into protein dry powder with spray dryer.
The present invention's cocoanut active charcoal is the fluorine ion adsorption aid, has safe and effective free from extraneous odour, meets the effect of food sanitation safe requirement, can't produce new salt, heavy metal and objectionable impurities.Utilize biological NF membrane technology that the fluorine ion in liquid is got rid of, safe and reliable, technology is simple, and is easy to operate, meets the krill albumen technological requirement of producing low fluorine content in enormous quantities.Can obtain ash content below 5%, the krill protein powder that fluorine content 10ppm is following, the rate of recovery of krill muscle protein can reach 45～55%.
