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 of collagen-containing whitening, anti-wrinkle and skin care freeze-dried powder. The invention controls the moisture content of the final product to be 5-8% by regulating the heating rate, temperature, vacuum degree and holding time of the stages of pre-freezing, primary sublimation and analytical drying in the freeze-drying process, and the obtained freeze-dried powder has stable properties, The appearance is beautiful, and the collagen activity is maintained at a high level.

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...
