Collagen peptide nutritional product and preparation method thereof

Abstract

The present invention provides a collagen peptide nutritional product and a preparation method thereof. Main raw materials comprise fish collagen peptides, pearl powder, a grape seed extract, citrus powder, xylitol, maltodextrin and vitamin C. Main preparation processes are as follows: firstly the raw materials are subjected to screening and fine inspection, then the inspected raw materials are subjected to a low-temperature baking treatment, the baked raw materials are finely ground and accurately mixed in proportion, and finally the mixture is automatically packaged by an automated device. The finely selected raw materials are used for the low-temperature baking, grinding and powder milling are conducted, nutrients are maximally prevented from being destroyed, the various raw materials are blended, so that the collagen peptide nutritional product helps skin repair and whitening, and at the same time, VC is supplemented and more conducive to body's own collagen synthesis and has a freckle-removing effect; and the grape seed extract is has much more anthocyanins, enhances body's antioxidant capacity, at the same time, inhibits elastase and collagenase to enable the skin to become smooth and full of elastic, prevents skin damage caused by excessive sun exposure from inside to outside, etc.

Description

technical field [0001] The invention relates to the technical field of bioengineering, and more particularly to a collagen peptide nutritional product and a preparation method thereof. Background technique [0002] Collagen is a macromolecule and is not easily absorbed by the skin. Collagen is insoluble. However, when collagen is hydrolyzed under the action of acid, alkali, heat and enzyme, collagen hydrolysate (peptide) will be produced. They have very similar amino acid composition and content. Due to the disintegration of macromolecules and the reduction of molecular weight, their solubility increases and they are soluble in cold water. These collagen hydrolysates have a special name, collagen peptides. Collagen peptides can be actively absorbed by the human body without being digested and can be fully utilized by body tissues. The absorption of collagen peptides is the key to improving skin elasticity and eliminating wrinkles. After the collagen peptides are fully abso...

Problems solved by technology

There are many types of collagen peptide products on the market, and the quality is uneven. The preparation method seriously destroys the nutritional content of its raw materials and cannot achieve the desired effect.
