Description

Osmanthus fragrans powder with whitening and antioxidation effects, and preparation method and application thereof Technical Field The invention relates to the technical field of food processing, in particular to osmanthus fragrans powder with whitening and antioxidation effects, and a preparation method and application thereof. Background Skin lightening is a complex physiological process that reduces skin pigmentation by interfering with the melanin metabolic process. The core is to inhibit melanin formation, block its transfer to the skin surface, and accelerate the metabolic shedding of the melanin that has been formed. Specifically, when skin is stimulated by ultraviolet rays or the like, tyrosinase is activated, thereby catalyzing the conversion of tyrosine to melanin. The whitening component (such as vitamin C and polyphenol) can inhibit tyrosinase activity, and reduce melanin yield from source, thereby reducing skin color. In addition, poor eating habits, irregular life and daily life, and long-term facing the computer screen, all of which can cause free radicals to be generated by skin, and cause aging of horny layer, so that the skin is dark yellow. The osmanthus fragrans serving as a special germplasm resource in China is rich in polyphenol active substances, so that the osmanthus fragrans has potential application value in the field of skin whitening. However, the traditional extraction process (such as hot water extraction method) has technical bottlenecks of low active ingredient retention rate, high impurity content and the like, and the industrialized application of the traditional extraction process is severely limited.
