Abstract

The invention discloses a preparation method for a purple sweet potato anthocyanin facial mask. The method comprises the following steps: 1) pre-treating fresh purple sweet potatoes; 2) adding acidified ethanol into the obtained purple sweet potato pulp, adding cellulase, performing ultrasonic treatment, performing sieving and filtering, performing separation and purification by macroporous resin,performing gradient elution, and performing concentration and drying to obtain a purple sweet potato anthocyanin extract; 3) performing enzymatic hydrolysis on silk, performing inactivation of enzyme, performing classification by ultrafiltration, and performing concentration and drying to obtain a silk fibroin peptide with a weight-average molecular weight of 2-10k; and 4) compounding the purplesweet potato anthocyanin extract and the silk fibroin peptide according to a ratio, adding other auxiliary materials, and performing uniform mixing to obtain the purple sweet potato anthocyanin facialmask. According to the method, the purple sweet anthocyanin extract obtained by pre-treating the purple sweet potatoes and performing extraction is compounded with the silk fibroin peptide accordingto the specific weight ratio, other auxiliary materials with a specific content are also used to prepare the purple sweet potato anthocyanin facial mask, and the obtained purple sweet potato anthocyanin facial mask is environmentally friendly and safe, and has excellent anti-acne, whitening, spot-fading and anti-wrinkle effects.

Description

technical field [0001] The invention relates to the field of purple sweet potato processing, in particular to a preparation method of a purple sweet potato anthocyanin facial mask. Background technique [0002] The root of purple sweet potato is rich in purple sweet potato pigment (Ipomoea batatas (L.) Lam), also known as anthocyanins (anthocyanins), the main components are cyanidin and paeoniflorin, it is a water-soluble pigment, and the content is red cabbage It is 2~3 times that of carrots. It has pure color, strong stability, and strong heat resistance and light resistance. At the same time, due to its structural characteristics, purple sweet potato anthocyanins have physiological functions such as anti-oxidation, antibacterial, anti-cancer, and liver protection. In addition, purple sweet potato is widely planted in my country and is an important source of natural pigments with a wide range of sources. However, currently, purple sweet potato anthocyanins are not widely...
