Problems solved by technology

However, in the existing freeze-drying process of collagen-containing products, the drying sublimation temperature is controlled too high (>40°C), which can easily lead to collagen inactivation. At the same time, the moisture control is not strict, and the product often collapses, shrinks, or has large crystal particles. The appearance of the product is loose, resulting in a product that is neither beautiful nor biologically active

Abstract

The invention discloses a freeze-drying method for skin-whitening, anti-wrinkle and skin-care freeze-dried powder containing collagen. According to the method, through regulation and control on the heating speeds, the temperatures, the vacuum degrees and the holding time in the pre-freezing stage, the primary sublimation stage and the analyzing drying stage in the freeze-drying process, the moisture content of the final product is controlled to range from 5% to 8%, and the obtained freeze-dried powder has the advantages that the properties are stable, the appearance is attractive, the activityof the collagen is kept at the relatively high level and the like.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and relates to a freeze-drying method of collagen-containing whitening, anti-wrinkle and skin care freeze-dried powder. Background technique [0002] Vacuum freeze-drying technology achieves the purpose of drying by directly sublimating the water in the sample from ice at a lower temperature (-10°C ~ -50°C), and the sample is not affected by surface tension during the drying process. Deformation and eventually dehydration of the material. Since the vacuum freeze-drying technology is carried out in a low-temperature and low-pressure environment, most of the biological reactions are stagnant, and there is no liquid water in the treatment process, and the water is directly sublimated in a solid state, so that the original structure and shape of the material are protected to the greatest extent, and finally the appearance and appearance are obtained. High-quality dry products with both intrinsic q...
