Problems solved by technology

However, this type of humectant also has its disadvantages: (1) the moisturizing effect is more easily affected by the humidity of the environment. When the relative humidity of the environment is too low, the effect of this type of humectant retaining water molecules will obviously decline; (2) limited Due to the moisturizing mechanism of this type of material itself, it is difficult to achieve the purpose of high-efficiency moisturizing, and its long-term moisturizing effect is not ideal; and (3) this type of moisturizing agent has no moisture-proof effect
At present, some polyhydric alcohols and amino acids are mainly used to keep the dry leaves of plants, especially tobacco, tea and roasted foods, such as seaweed quaternary ammonium salts and compound moisturizers, etc., but the moisturizing effect is not ideal, and it is also Does not have moisture-proof effect

Embodiment 1

[0041] Example 1: Preparation of moisturizing and moisture-proof composition

[0042] The moisturizing and moisture-proofing composition or the moisturizing and moisture-proofing agent of the present invention is prepared by the following steps:

[0043] According to the weight in Table 1 below, each component was accurately weighed to prepare formula 1, formula 2, and formula 3 of the moisturizing and moisture-proof composition of the present invention. Under normal temperature conditions, the weighed sucralose is prepared into a 10% by weight propylene glycol solution, that is, solution (a); Luo Han Guo extract (purchased from Shaoxing Shenfeng Spice Co., Ltd.) is prepared into a 10% by weight aqueous solution , Which is the solution (b); add Tremella heteropolysaccharide (purchased from Shanghai Huiwen Biotechnology Co., Ltd.), solution (a) and solution (b), as well as glycerin, propylene glycol and hyaluronic acid in sequence in the flavoring kettle, and Stir for 25 minutes to...

Embodiment 2

[0047] Example 2: Film-forming properties of the moisturizing and moisture-proof composition

[0048] Experiment 1

[0049] The moisturizing and anti-moisture agent (formulation 1), Tremella heteropolysaccharide, sodium hyaluronate, and glycerin prepared in Example 1 were prepared with water to form a 1% by weight aqueous solution, and then each aqueous solution was placed in an evaporating dish at a temperature of 50°C and humidity Drying is performed under the condition of 25% to form a film of 15 mm×15 mm. The original area of ​​each film was measured, and the original area of ​​the film was determined to be 100%. Then the formed film was placed on a polytetrafluoroethylene plate (temperature 25°C, relative humidity 87%) and kept for 24 hours. Then, the temperature and humidity conditions were changed to a temperature of 25°C and a relative humidity of 15%, and kept for 8 hours. Then measure the area of ​​each membrane and compare it with its original area (see attached figur...

Embodiment 3

[0052] Example 3: Moisturizing performance

[0053] This example is an experiment used to compare the moisturizing properties of the moisturizing and moisture-proofing agent of the present invention, Tremella heteropolysaccharide, sodium hyaluronate and glycerin.

[0054] The moisturizing and anti-moisture agent (formulation 1), Tremella heteropolysaccharide, hyaluronic acid and glycerin prepared in Example 1 above were formulated into a 1% by weight aqueous solution and sprayed evenly on the same filter paper. The filter paper was kept at a temperature of 25° C. and a relative humidity of 30% RH for 7 days.

[0055] By testing the weight of each filter paper before and after the experiment, from the weight difference of the sample before and after the experiment, use the following formula to calculate the moisture retention rate of the sample:

[0056] Moisturizing rate (%) = 1-100×(W 3 -W 2 ) / W 2

[0057] Where W 2 Is the weight of the sample before the experiment; W 3 It is the weig...

Abstract

The invention relates to a moisturizing and moistureproof composition and an application thereof and a moisturizing and moistureproof method. Based on the total weight of the moisturizing and moistureproof composition, the moisturizing and moistureproof composition comprises 0.01-50.0% of tremella heteropolysaccharide, 0.02-5.0% of momordica grosvenori extract, 0.01-1.0% of trichlorosucrose, 3.0-15% of glycerol, 3-8% of hyaluronic acid and 20.0-85.0% of propylene glycol. The moisturizing and moistureproof composition can form a biomimetic membrane on the surface of material, especially the surfaces of dry leaves of plants and the surface of baking food, and sensitivity of moisture in the material to the environment is reduced, thus moisturizing and moistureproof effects are achieved. Compared with the traditional polyalcohol and amino acid moisturizers, or sodium hyaluronate and tremella heteropolysaccharide moisturizers, the moisturizing and moistureproof composition provided by the invention has more excellent membrane-forming performance, more excellent membrane flexibility and higher moisturizing ability and moistureproof performance.

Description

Technical field [0001] The invention relates to a moisturizing and moisture-proofing composition and its application, and a method for moisturizing and preventing moisture. More specifically, it relates to a moisturizing and moisture-proof composition comprising Tremella heteropolysaccharide, Luo Han Guo extract, moisture absorption agent, sealing agent and hydrophilic matrix and its application in moisturizing and moisture-proofing the surface of dried plant leaves and baked food , And the method of using the composition to moisturize and prevent moisture. Background technique [0002] Generally, a moisturizer is moisturizing by retaining moisture and / or forming a protective film on the surface to prevent volatilization of moisture. Currently, most of the commonly used moisturizers on the market fall into two categories: polyols and amino acids. Polyol moisturizers, such as glycerin, propylene glycol or sorbitol, produce moisturizing effects due to their hygroscopicity. Althou...
