Description
Technical field
The present invention relates to bone calcium extraction process, belong to food processing field.
Background technology
Along with the aging of society, in western countries, the illness rate of osteoporosis occupies first of metabolic bone disease.The misery that the osteoporosis illness brings patient and family is self-evident.According to statistics, China has approximately at present and surpasses 100,000,000 patients with osteoporosis, expects the year two thousand fifty will be increased to 200,000,000 1 thousand ten thousand people.Cause the factor of increasing people's calcium deficiency: live and work rhythm is accelerated, operating pressure is large and live irregular, the structure that is not careful in one's diet reasonably combined, calcium was taken in and was less than 600 milligrams of persons and can thinks the calcium insufficiency of intake every day, easily caused the shortage of calcium in the body; Some a middle-aged person's work strains lack self health consciousness, think little of outdoor activity, and proper interior synthetic vitamin D is reduced, and affect absorption and the utilization of calcium; Nutrition is taken in unbalanced or is lacked the necessary nutrient of human body.
The calcium agent of existing market mostly is the synthetic calcium of industry.The calcium agent nutritional labeling that industry is synthesized is single, is difficult to satisfy many-sided nutritional need in the bone growth metabolic process, and effect of supplemented calcium is undesirable.Animal Bone is rich in the several kinds of mineral elements such as calcium, phosphorus, iron, magnesium, and with people's bone photo seemingly, the skeleton cell has stronger affinity to homologue's cell, thereby utilization rate is higher.
Chinese patent CN1087793A and US Patent No. 6342252B1 disclose a kind of technique of utilizing enzyme solution to extract the calcium element from ox bone.Enzymolysis bone calcium has suitable, nutritious, the calcareous absorption rate high of calcium phosphorus ration.From the market sale situation, enzymolysis bone calcium is subjected to liking of consumers in general deeply, takes the osteoporotic successful of rear improvement, has obtained significant economic benefit.
But in the bone calcium that above-mentioned technique makes, degreasing method mainly is to implement in the boiling mode, is difficult to remove the fat of high-load in the sclerotin, causes final product fat content higher, simultaneously because smelling of fish or mutton taste is difficult to removal, mouthfeel extreme difference.For the consumer with angiocardiopathy, the hazards that too high fat intake obviously can raise and fall ill.Therefore, from animal skeleton, extract in the process of calcium element, remove excess fat, reduce the onset risk of angiocardiopathy, have simultaneously and can remove smelling of fish or mutton taste, improve mouthfeel, become technical staff's urgent problem.
Summary of the invention
The object of the present invention is to provide a kind of extraction process of new enzymolysis bone calcium, described technique can better be removed fat in the sclerotin than prior art.
Another object of the present invention provides a kind of more healthy calcium supplementing product production technology, and the calcium supplementing product that described technique makes has lower fat content, has again splendid mouthfeel simultaneously.
Another object of the present invention provides a kind of calcium supplementing product with market competitiveness, and described product is not because of degreasing and go the design of smelling of fish or mutton technique to increase production cost,
For achieving the above object, the present invention adopts following technical proposal to realize.
The present invention adopts three degreasing modes to remove animal oil, is 60～80 ℃ for the first time, 45～75min; 80～90 ℃ for the second time, 30min; The lipase enzymolysis for the third time.Three degreasings also have the effect of sterilization simultaneously except having the fatty effect of removing in the sclerotin.For strengthening degreasing effect, the present invention preferably is broken to bone meal 5～40mm particle, the too small production cost that then increases of particle, and the excessive degrease effect of particle is relatively poor.The inventor determines finally that through test of many times and experience 5～40mm granulometric range reaches the best cost performance of bone fat and cost.
After the alcohol steep degreasing, the present invention also adopts the hot-water soak rinse method to remove the fat that exists in the aggregate; Again with 4000～8000r/min, centrifugal 30min can remove most fat in the aggregate like this after the rinsing.
For further removing remaining fat, process choice of the present invention again adds alkaline lipase and carries out fat remaining in the enzymolysis aggregate after centrifugal.Alkaline lipase A, B account for 0.1～0.4%, 20～30 ℃ of aggregate weight ratios by 1.5～3: 1 compound lipases that mixes, hydrolysis 40～60min.Behind enzymolysis, secondary centrifuging is further removed remaining trace fat.
The present invention adopts the method for fermentation that the aggregate before fermenting is carried out preliminary treatment, and then carries out enzymolysis and extraction calcium element, and then extract is carried out fermentation process, removes the peculiar smell in the extract, improves mouthfeel.
For strengthening ferment effect, the present invention preferably is broken to aggregate 5～40mm particle, the too small production cost that then increases of particle, and the excessive effect of particle is relatively poor.The inventor determines finally that through test of many times and experience 5～40mm granulometric range reaches the best cost performance of the extraction of calcium element and cost.
Enzymolysis primary fermentation of the present invention adopts lactic acid bacteria and aggregate by certain weight proportion, and 35～50 ℃, fermentation 12h.The weight proportion of lactic acid bacteria and aggregate, lactic acid bacteria concentration, fermentation temperature and the time in zymotic fluid has important impact to the product Free Calcium content that finally makes, and the weight proportion of lactic acid bacteria and aggregate and the lactic acid bacteria concentration in zymotic fluid having the greatest impact to free calcium.The inventor determines after the repetition test that according to oneself working experience for many years it is 0.01～0.04% that lactic acid bacteria accounts for the aggregate weight ratio, under the condition of aggregate and water w/v 1: 3～5, can reach the best cost performance of input and output.
The inventor provides great many of experiments, it is unexpected that the various lactobacillus of finding ferment according to certain proportioning combination, final product Free Calcium content improves more than 8% with certain lactobacillus-fermented more separately, and it is better to adopt bifidobacterium lactis (B.lactis), lactobacillus bulgaricus (L.bulgaricus) and three kinds of lactic acid bacterias of Lactobacillus helveticus (L.helviticus) to carry out ferment effect; Adopt these three kinds of lactic acid bacteria proportioning after fermentation effects best, when three kinds of lactic acid bacterias make up with weight ratio at 1: 3: 2, improve 10%～30% behind the more single lactobacillus-fermented of enzymolysis liquid Free Calcium content.
Secondary fermentation of the present invention adopts leuconostoc cremoris and citric acid, and the proportioning between the two all has important impact to taste, the production efficiency of end product.The inventor determines that finally the end product effect of fermentation is better under the condition of leuconostoc cremoris and citric acid w/v 1: 20～30.Under these conditions, determine that fermentation temperature is 39 ℃, when fermentation time is 12h, can reach the optimization of production efficiency.
The present invention adopts the method for high-temperature sterilization to reach the purpose of sterilizing, also removes the lactic acid bacteria in the enzymolysis liquid simultaneously.
Enzymolysis of the present invention adopts the complex enzyme hydrolysis method, and after screening, final discovery is carried out enzymolysis with bromelain and papain and had better effect than other protease.Certainly, select other protease to carry out enzymolysis and also can realize purpose of the present invention.Best enzymolysis scheme is the compound protease that zymotic fluid adds bromelain and papain weight ratio 1: 2～5 in the extraction process of the present invention, and adding citric acid is transferred pH value to 4～6,40～60 ℃ stirring 40～60min.
The used compound protease of hydrolysis aggregate accounts for aggregate weight ratio 0.05～0.2%.
The alkaline lipase that alkaline lipase A is produced by the Penicillium expansion PF868 of bioengineering institute of Fujian Normal University development, Co., Ltd provides by the green little health bioengineering in Shenzhen; Alkaline lipase B adopts biotechnology to be made with extra care and the alkaline lipase of generation by fungi fermentation, is provided by Haining Jin Chao Industrial Co., Ltd..
