Abstract
The invention relates to a method for preparing a collagen product from a raw material of animal skin. The method comprises the steps of: cleaning animal skin subjected to surface treatment by water, and then crushing the animal skin into skin mud by a chopping machine; adding water to the skin mud, smashing the skin mud by a colloid mill and a homogenizer, adding protease, and treating the skin mud by ultrasonic for 20-120min for enzymolysis; and separating the material treated with enzymolysis by a disc separator to remove fat and solids, so as to obtain a liquid collagen product, which can be directly used as a raw material for beverage processing. The obtained liquid collagen can be concentrated and dried to obtain a collagen powder, which can be used as a raw material for producing food rich in collagen. The present invention makes full use of animal skin resources to develop a novel collagen food product, which can also be used as a base material or an accessory for other food products, and produced into other food products, such as beverages, bakery products, meat products, protein beverages and infant food.
Description
Technical field
The present invention relates to a kind of method of using animal skins to produce collagen product.
Background technology
At present, protein product is a lot of on the market, take soybean protein as many, the oviductus ranae collagen is arranged also, and ass-hide glue is also arranged, animal gelatine, but use other animal skins to produce the few of albumen.Animal skins contains more collagen, and its nutritive value is very high, in order to utilize fully the animal skins resource, animal skins is removed fat, make the collagen food goods, not only be conducive to taking full advantage of of animal skins, and be conducive to the absorption of human body, be of great benefit to for strengthening compatriots' physique.
Summary of the invention
The object of the invention is to propose a kind of take the method for animal skins as the waste collagen product, utilize fully the resource of animal skins, develop a kind of new collagen food goods.
The present invention may further comprise the steps take the method for animal skins as the waste collagen product:
Animal skins after the surface treatment is washed, then pulverize cutification mud with cutmixer;
In skin mud, add water, add protease through colloid mill, homogenizer after pulverizing, process 20～120min enzymolysis through ultrasonic wave;
Material after the enzymolysis processing is removed fat and solids through disc separator, namely obtains liquid collagen product, can be directly as the raw material of beverage processing.
The above-mentioned liquid collagen that obtains is obtained collagen protein powder after concentrated, drying, can be used as and make the raw material that is rich in collagen food.
Good effect of the present invention is: utilize fully the animal skins resource, develop a kind of new collagen food goods.Also can be used as base-material or the auxiliary material of other food product, make other food product, such as various beverages, baked product, meat products, protein drink, infant foods etc.Animal skins is removed fat, make the collagen food goods, not only be conducive to taking full advantage of of animal skins, and be conducive to the absorption of human body, build up health.
