The preparation method mainly comprises the following steps: 1, cleaning bones; 2, adding the bones into a heating kettle with an opening, taking grease as a heating medium and heating to remove moisture and fat in the bones; 3, performing mechanical pulverization on the heated bones to obtain crude bone meal; 4, removing or non-removing grease in the crude bone meal; and 5, dispersing the crude bone meal in the solution to obtain the nano-bone paste through the high-pressure homogenization method, and drying the paste to obtain the nano-bone meal with the average grain diameter of 100-1,000 nm. The method overcomes the defects in the traditional high-temperature cooking method that the process is complex, the utilization rate of material is low and the product quality is unstable; and the prepared nano-bone meal has the advantages of small grain diameter, uniform distribution, high dispersion speed, good absorbing effect and mellow taste, can be eaten or applicable to the field of food, feed and the like as an additive, and has a broad market prospect.
Description
Technical field
The present invention relates to food processing and material preparation science field, be specifically related to a kind of preparation method of nanometer bone meal.
Background technology
Animal bone contains abundant calcium, phosphorus, grease and protein, is important mineral matter element and nutriment source.Usually, all be that bone is processed into bone meal utilization.The content of calcium is significantly higher than other food in the bone meal, and with people's bone photo seemingly, so calcium utilization is high, is the excellent selection of replenishing the calcium.In addition, collagen content is high in the bone meal, and fat content is low, and fatty acid proportion is reasonable, is a kind of high nutrition, food low in calories.In recent years, bone meal is widely used in the fields such as food, feed, pharmacy, fine chemical product and pottery manufacturing.
At present, the preparation method of bone meal mainly is first with the boiling of bone HTHP, then obtains bone meal through techniques such as super-dry, pulverizing.For example, patent CN102068004A has announced a kind of bone meal preparation method, and its main technique is boiling, calcining, pulverizing; Patent CN102726599A by methods such as thermophilic digestion degreasing, filtration, oven dry, has obtained fishbone dust take fish-bone as raw material; Patent CN102429249A discloses a kind of preparation method of nanometer yak bone meal, and the method obtains the nano yak bone powder of particle diameter 100-300nm through techniques such as cleaning, boiling, oven dry, one-level pulverizing, secondary pulverizing, ultra micro air-flow crushing, dehydrations.Said method all will pass through the processes such as thermophilic digestion, filtration, drying, pulverizing, and complex process, energy consumption is large, labour intensity is large, the sex change of rotting easily of the bone after the boiling, unstable product quality; In addition, can produce a large amount of feed liquids after the boiling, be difficult to process, cause easily environmental pollution and the wasting of resources.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of its preparation method of nanometer bone meal is provided, is a kind of take oil phase high-temperature heating method as the basis, prepares the method for nanometer bone meal by high-pressure homogeneous process.The method is removed the moisture in the bone and grease by oil phase heating, obtains the bone of loose drying, and bone is through mechanical disintegration, the process such as high-pressure homogeneous and dry, obtains that particle diameter is evenly distributed, the nanometer bone meal of favorable dispersibility.Nano particle is because its particle diameter is little, specific area is large, and good hydrophilic property is absorbed by human body easily, can significantly improve the bioavilability of particle.Therefore, by nanocrystallization technology, bone is prepared into nanometer bone meal, can promotes digesting and assimilating of it on the one hand, improve bioavilability; In addition on the one hand, also can improve the fine and smooth soft and smooth degree of bone meal, improve mouthfeel.
The objective of the invention is to finish by following technical solution.The preparation method of this nanometer bone meal, take oil phase high-temperature heating method as the basis, by the high-pressure homogeneous method for preparing nanometer bone meal, prepared nanometer bone meal favorable dispersibility, particle diameter are evenly distributed, average grain diameter is between 100-1000nm, and the method comprises following step:
(1) bone cleans, and with clear water the blood stains, the fur foreign material that adhere on the bone is removed;
(2) oil phase heating adds the uncovered heating kettle that fills grease with the bone after cleaning, and keeps temperature in the kettle at 100-150 ℃, heats 0.5-2 hour, controls afterwards temperature at 150-200 ℃, continues heating 0.1-1 hour, in the time of heating bone is stirred;
(3) pulverize, the bone that step (2) obtains is pulverized with mechanical crusher, pulverizer screen pack size is the 10-200 order;
(4) degreasing, the skeleton soil after the pulverizing are removed or are not removed grease, are prepared into not contain grease or rich grease-contained nanometer bone meal;
(5) high-pressure homogeneous, skeleton soil is dispersed in the mixed solution of water, solvent or water and solvent, under pressure 50-150Mpa, high-pressure homogeneous 5-20 time, obtain the nano bone slurry, wherein the particle diameter of particle is at 100-1000nm;
(6) product drying, the nano bone slurry obtains nanometer bone meal through super-dry.
Described grease is lard, butter, palm oil or diglyceride and their mixture.
Among the present invention, the method for removing grease is, with solvent skeleton soil is dispersed in wherein, and is then centrifugal or filter, and obtains not grease-contained skeleton soil.
Described solvent is one or more the mixed solution in methyl alcohol, ethanol, acetone, butanone and the oxolane.
Described drying means is spray-drying, freeze drying, vacuum drying or aeration-drying.
Described nanometer bone meal can be Os Sus domestica powder, bovine bone powder, yak bone meal and fishbone dust etc.
Beneficial effect of the present invention is: (1) traditional HTHP cooking process time is long, and the bone after the boiling is apt to deteriorate, must just can carry out following process through super-dry, and after the boiling remaining reduction of feed volume large, be difficult to process.The present invention adopts the oil phase heating, and resulting bone moisture-free can directly carry out the techniques such as follow-up pulverizing, nanometer.(2) in the conventional method, the meat on the bone and fat enter in the water through boiling, are difficult to separate, and material utilization is low, and easily causes environmental pollution.Among the present invention, bone is through the oil phase heating, and fat enters oil phase, and the moisture in the meat is evaporated to be removed, and can carry out following process together with bone, and all substances have all obtained effective utilization, have also increased simultaneously the content of middle bone meal nutriment.(3) through the oil phase heating, increased the fragrance of bone, resulting bone meal mouthfeel sweet-smelling.(4) the prepared bone meal of the present invention is in nanoscale, and its particle diameter is little, be evenly distributed, and dispersed speed is fast, good absorbing effect.(5) the nanometer bone meal of the present invention's preparation can eat, and also can be used as additive application in fields such as food, feeds, has wide market prospects.
