Embodiment 1

[0037] A preparation method of a glycine-rich collagen polypeptide in this embodiment, the specific preparation steps are as follows:

[0038] (1) After cleaning the tilapia skin with deionized water, cut it into pieces of 1 × 1cm size, then add the fish skin pieces into a 100mL conical flask, add 0.8mmol / L NaOH solution (fish skin: solution =1:7, g / mL), soak for 2 hours to remove impurity proteins, then rinse with deionized water repeatedly until neutral. Add 0.6wt.% HCl, soak for 1h (fish skin: solution = 1:7, g / mL), and then rinse repeatedly with deionized water until neutral to obtain washed fish skin.

[0039] (2) Add sterile water and mix with the washed fish skin, the ratio of material to liquid is 1:15 (g / mL), extract at a constant temperature of 40-60°C for 12 hours, and then centrifuge (10000r / min, 20min), the obtained supernatant Freeze-dried, that is, collagen.

[0040] (3) Enzyme hydrolyze collagen with protease, collagen substrate concentration is 10wt.%, enzym...

Embodiment 2

[0051] A formaldehyde scavenger of the present embodiment is composed of: using deionized water as a solvent, containing 8wt.% collagen polypeptide with a molecular weight of 1kDa<MW<3kDa obtained in Example 1, and 2wt.% apple polyphenols (commercially purchased) .

Embodiment 3

[0053] A kind of formaldehyde scavenging agent of the present embodiment, its composition is: take deionized water as solvent, containing 10wt.% the collagen polypeptide that the molecular weight obtained in embodiment 1 is 1kDa<MW<3kDa, 2wt.% red grape polyphenol (commercially purchased ).

Abstract

The invention belongs to the technical field of functional polypeptides and discloses a collagen polypeptide rich in glycine and a formaldehyde scavenger prepared therefrom. The collagen polypeptide is prepared from the following steps: extracting collagens by means of a hot water extraction method; and then preparing the collagen polypeptide rich in glycine by enzymolysis of the collagens by means of protease by taking Tilapia mossambica waste as a raw material. By being combined with plant polyphenol compounds, the quick, long-acting, safe and edible formaldehyde scavenger is prepared. The formaldehyde removal rate of the formaldehyde scavenger can reach 95% or above within 10 min, so that the problem that a single amino acid is not ideal in removing formaldehyde is solved. A colloid film which is 2-10 microns can be formed on the surface of an object such as furniture if being dried to inhibit further release of formaldehyde. The formaldehyde removal rate can be kept at 95% or abovewithin three months, an effect of removing formaldehyde for a long time is achieved, and the problem that existing formaldehyde removal products are rebound in effect and short in effective period issolved.

Description

technical field [0001] The invention belongs to the technical field of functional polypeptides, in particular to a glycine-rich collagen polypeptide and a formaldehyde scavenger prepared therefrom. Background technique [0002] In recent years, with the development of scientific society and the improvement of people's living standards, people pay more and more attention to various health problems. The main environment where people live, study and work in their lives is indoors. Therefore, the quality of the indoor environment directly affects people's health. The main source of air pollution is a serious threat to people's health. Formaldehyde is the main enemy of indoor air pollution. It has the characteristics of continuous release for as long as 3 to 15 years, and it mainly comes from artificial wood boards, which are decorative materials. Formaldehyde has stimulating and sensitizing effects on skin and mucous membranes, which can cause headaches, eye pain, allergic der...
