Embodiment 1

[0035] [Example 1] The preparation method of milk fermentation product filtrate

[0036] Preparation of milk fermentation product filtrate: Weigh a certain amount of milk and water according to the ratio of 1:9 to obtain fermentation culture solution; after sterilizing at 95°C for 20 minutes, insert probiotics at an amount of 60g / ton, among which Lactobacillus plantarum and each 30g / ton of Bifidobacterium lactis to obtain a fermentation system. Ferment the fermentation system in a 37°C incubator for 48 hours to obtain a fermentation product; centrifuge the fermentation product at 6500r / min and a centrifugal radius of 9cm for 20min, discard the precipitate, collect the centrifuged supernatant, and filter it with a 0.22μm filter membrane After filtering, the supernatant was autoclaved at 108° C. for 20 minutes to obtain a sterilized fermentation filtrate, which was the milk fermentation product filtrate provided by the present invention.

Embodiment 2

[0037] [Example 2] Application of milk fermented product filtrate as cosmetics

[0038] 1. Safety testing of milk product fermentation filtrate

[0039] The human patch test is mainly used to detect the irritation of cosmetic final products or raw materials. The present invention conducts a human body closed patch test on the milk fermented product filtrate obtained in Example 1, aiming at evaluating its potential skin irritation.

[0040] 1. Test object

Abstract

The invention relates to a milk fermented product filtrate as well as a preparation method and application thereof. The milk fermented product filtrate comprises active ingredients extracted after fermentation of a milk culture medium and probiotics, wherein the probiotics is a mixture of lactobacillus and bifidobacterium; and the dosage of the probiotics is 40-80g per ton. According to the invention, water and milk are proportionally mixed according to proportion to obtain the milk culture medium, then the probiotics is added into the milk culture medium for fermentation in specific conditions, and finally, the fermented product is treated to obtain the milk fermentation product filtrate. Without any chemical component, the milk fermented product filtrate can be directly used as cosmetics such as mask, essence and toner while causing zero load on skin; and moreover, the fermented ingredient contains micro-molecule polypeptide which is easily sufficiently absorbed by skin. In the invention, by adopting edible probiotics for fermentation, the milk fermented product filtrate is beneficial to skin health and avoids the pollution of enzymes, chemicals and the like; and moreover, the conditions are mild, the operation is easy, the production steps are simplified, the production cost is lowered, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a milk fermentation product filtrate and a preparation method and application thereof. Background technique [0002] Skin care products first have the function of beautifying the skin, which can enhance the elasticity and vitality of the skin. Secondly, they can make people young and beautiful. Skin care products enhance people's self-confidence, improve people's beautiful image, and promote social civilization.
