Description
Technical Field
The invention belongs to the technical field of food, and particularly relates to high-calcium high-collagen food and a preparation method thereof.
Background
Calcium is an essential element for living beings, and is a protein bound by calcium in muscles, nerves, body fluids and bones, so that the growth and health of the human body are affected by insufficient calcium content. The existing research shows that amino acid-bound calcium is more beneficial to human body absorption than inorganic calcium, and the amino acid-bound calcium refers to an organic calcium substance produced by chemical synthesis reaction of various amino acids and inorganic calcium salt, but the existing food-grade amino acid-bound calcium has lower binding rate, so that the absorption and digestion rate of calcium is lower.
The collagen has the effects of beautifying and body building, has good biocompatibility, biodegradability and bioactivity, is easy to be absorbed by human bodies in vivo, can promote cell survival and growth, promote platelet coagulation and the like, and is widely applied to the field of food. Collagen extraction is generally classified into the following three types: one is a high-pressure assisted physical method; secondly, a chemical method combining solvent pretreatment with low-temperature or hot water extraction is adopted, and according to different solvents, a hot water extraction method, an acid method, an alkaline method and a salt method can be adopted; and thirdly, a biochemical method using enzyme. However, these methods generally have the problems of low extraction rate and low utilization rate of collagen.
The food is added with a proper amount of amino acid to combine calcium and collagen, so that the nutritional ingredients of the food can be effectively enriched, and the calcium and the collagen can be absorbed by a human body.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a method for preparing high-calcium high-collagen food, calcium in the food is amino acid-bonded calcium, the bonding rate is high, and the calcium absorption effect is good; the extraction rate of collagen is high.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for preparing high calcium and high collagen food comprises the following steps:
s1, boiling the animal bones with meat at high temperature, embrittlement treating at low temperature, and then grinding with variable spherical diameter under an acidic condition to obtain amino acid-bound calcium, wherein the pH value during grinding is 5-6.5;
s2, placing animal skin, scales and/or hoof tissues in an alkaline aqueous solution for boiling, and stirring at a high speed to obtain collagen sol; the pH value of the alkaline aqueous solution is 7.2-8.5, and the temperature is 100-121 ℃;
s3, mixing the amino acid combined calcium and the collagen sol according to a proportion, adding the ingredients, adjusting the pH, and carrying out high-pressure recombination to form the high-calcium high-collagen food.
Further, in the technical scheme, the mass ratio of meat to bones in the skeletons with meat in the step S1 is 0.1-5: 100; the cooking time is 10-60 min; the low-temperature embrittlement treatment parameters are as follows: freezing at-10 to-30 ℃ for 10 to 50 hours.
Further, in the technical scheme, the mass ratio of the amino acid bonded calcium to the collagen sol in the step S3 is 0.1-50: 100, and the pH value is 6.5-7.0.
Further, in the above technical solution, the method for variable-diameter grinding in step S1 includes: ball milling is carried out by adopting a ball mill, and the ball mill has the following parameters: the rotating speed is 1500-3000 r/min, the diameter of the grinding ball is 0.3-0.7mm accounting for 30-60%, the diameter of the grinding ball is 0.8-1.7mm accounting for 20-40%, and the diameter of the grinding ball is 1.8-3.0mm accounting for 10-30%.
Further, in the above technical solution, in step S3, the ingredients are water and flavoring, the mass ratio of the amino acid bonded calcium/collagen sol to the flavoring to the water is (5-15): 1-2): 100, and the flavoring is sugar: salt: 1, (0.1-2) and (1-1.5) of citric acid, and the high-pressure recombination used instrument is a stone mill.
Further, in the above technical solution, in step S3, the ingredients include rice, salt and monosodium glutamate in an amount of 1 (0.01-0.05) to 0.005-0.01, the mass ratio of the amino acid-bonded calcium/collagen sol to the ingredients is 5-30: 100, and the high-pressure recombination parameters include: a double-screw extruder is adopted, the pressure is 0.1-0.3Mpa, and the shearing force and the kneading force are 1 (1.1-1.35).
Further, in the technical scheme, in the step S3, the ingredients comprise meat paste, seasoning, starchy material and amino acid bonded calcium/collagen sol, wherein the mass ratio of the amino acid bonded calcium/collagen sol to the ingredients is (0.5-1): 0.05-0.1): 1, the high-pressure recombination parameters are as follows: adopting a double-screw extruder, wherein the pressure is 0.1-0.3Mpa, and the shearing force is as follows: the kneading force is 1 (1.25-1.35).
