Problems solved by technology

Although these facial masks can achieve a certain beauty and skin care effect, there are also obvious defects as follows: (1) the non-woven facial mask has poor affinity with the skin, and is only a carrier of the essence, and the skin has obvious abnormal reactions when it contacts it; (2) ) The non-woven mask has a low adsorption capacity, resulting in a large amount of essence remaining in the mask bag or dripping, which cannot be effectively used; (3) chemical preservatives such as niacinamide, salicylic acid, vitamin A alcohol, etc. are added, which are safe Hidden danger
The main disadvantage of this method is: the preparation of fruit and vegetable semen needs to consume a large amount of fruits and vegetables, and these fruits and vegetables are not on the market in different seasons, which requires sp

Embodiment 1

[0022] A kind of novel method for preparing skin-friendly composite protein facial film, the concrete steps of described method are as follows:

[0023] (1) Preparation of small molecule rice protein peptide solution

[0024] Using commercially available defatted rice protein as raw material, according to the ratio of defatted rice protein mass (kg): pure water volume (L) ratio of 1:8, first pump pure water into the reaction tank, and then at a speed of 2000r / min Put in defatted rice protein under the condition of stirring, add dilute NaOH solution to adjust the pH to 8, then pass steam into the interlayer of the reaction kettle, heat up to 50°C, add 0.5% alkaline protease, carry out enzymatic hydrolysis for 1 hour, and then add 0.5% Flavor protease continued to enzymatically hydrolyze for 2 hours. After the enzymolysis was completed, the solution was pumped into a horizontal screw centrifuge, and centrifuged at a speed of 2500r / min. The centrifuged supernatant and centrifugal...

Embodiment 2

[0032] A kind of new method of preparing skin-friendly composite protein facial mask, same as embodiment 1, wherein:

[0033] In step (1), according to the ratio of defatted rice protein mass (kg): the ratio of pure water volume (L) to 1: 10, first pump pure water into the reaction tank, and then at a rotating speed of 2500r / min Put in defatted rice protein, add dilute NaOH solution while stirring to adjust the pH to 9, then pass steam into the interlayer of the reaction kettle, heat up to 55°C, add 2.5% alkaline protease, carry out enzymatic hydrolysis for 1.5h, and then add 2% flavor The protease continued to enzymatically hydrolyze for 3 hours. After the enzymolysis was completed, the solution was pumped into a horizontal screw centrifuge, and centrifuged at a speed of 3000r / min. The centrifuged supernatant and the centrifugal precipitate were collected respectively. Liquid, which is a small molecule rice protein peptide solution with a molecular weight of 613Da, is used to...

Embodiment 3

[0038] A kind of new method of preparing skin-friendly composite protein facial mask, same as embodiment 1, wherein:

[0039] In step (1), according to the ratio of defatted rice protein mass (kg): the ratio of pure water volume (L) to 1: 12, first pump pure water into the reaction tank, and then at a rotating speed of 3000r / min Put in defatted rice protein, add dilute NaOH solution while stirring to adjust the pH to 10, then pass steam into the interlayer of the reaction kettle, heat up to 60°C, add 4% alkaline protease, carry out enzymatic hydrolysis for 2 hours, then add 3% flavor protease Continue enzymatic hydrolysis for 4h. After the enzymatic hydrolysis is completed, the solution is pumped into a horizontal screw centrifuge, and centrifuged at a speed of 3500r / min. The collected centrifuged supernatant, which is a small molecule rice protein peptide solution with a molecular weight of 500Da, is used For the preparation of complex protein solutions.

Abstract

The invention provides a novel method for preparing a skin-protective composite protein facial mask. The method adopts commercial defatted rice protein and collagen as raw materials, and comprises the following steps: preparing a small-molecular rice protein peptide solution; preparing a small-molecular collagen peptide solution; preparing a composite protein solution; and preparing the composite protein facial mask. According to the produced composite protein facial mask, the effective component rice protein-collagen composite protein is bonded to cellulose non-woven fabric facial mask paper through an ether bond of glycidyl ether, the bonding is firm and cannot easily fall, the facial mask paper can be repeatedly used to reduce cost; the facial mask is mild and non-irritative to skin by combining the advantages of non allergy of rice protein and strong skin-protection of collagen; furthermore, the facial mask is weak in adsorption capacity to nutrition and functional factors, so that nutrition and functional factors can easily infiltrate into skin and supply nutrition to skin in time. A certain amount of wetting agent, antioxidant, emulsifier, essence and other nutritional factors are added into the prepared composite protein facial mask, and the facial masks are filled into bags to prepare different types of facial mask finished products. The facial mask is wide in application.

Description

1. Technical field [0001] The invention belongs to the field of facial mask preparation, and in particular relates to a new method for preparing a skin-friendly composite protein facial mask. 2. Background technology [0002] Mask is an essential maintenance product in modern women's skin care products. It covers the surface of the skin and plays the role of isolating air, infiltrating, softening the cuticle, expanding pores and sweat glands, promoting blood circulation of the skin and allowing the active ingredients in the mask to penetrate into the skin, etc. , is loved by more and more consumers. At present, the facial masks on the market are all made of man-made fiber non-woven fabrics or natural fiber non-woven fabrics through processes such as folding, bagging, injecting soaking liquid, and sealing, such as My Beautiful Diary created by Taiwan Uni-President Pharmaceutical Co., Ltd. A series of facial masks and MG brand facial masks of Meiji Holdings International Co.,...
