Extraction method of common bletilla tuber extract, whitening and beautifying porridge with common bletilla tuber extract, and preparation method thereof

Abstract

The invention discloses an extraction method of a common bletilla tuber extract, a whitening and beautifying porridge with the common bletilla tuber extract, and a preparation method thereof. The whitening and beautifying porridge with the common bletilla tuber extract is prepared from the following raw materials in parts by weight: 40-160 parts of glutinous rice, 2-10 parts of edible salt, 3-10 parts of carrots, 1-15 parts of pumpkins, 2-6 parts of shiitake mushrooms, 2-12 parts of coix seeds, 2-10 parts of honey, 0.5-20 parts of a common bletilla tuber extract, 1-5 parts of a chimonanthus salicifolius leaf extract, 0.5-5 parts of a white mulberry root bark extract, 1-10 parts of a ginkgo leaf extract, 1-5 parts of a grape seed extract, 1-8 parts of a liquorice root extract, 2-8 parts ofa rubus coreanus fruit extract, 1-15 parts of a jasmine flower extract and 600-1200 parts of water, wherein the common bletilla tuber extract is prepared by adopting a biological enzymolysis method and an ultra-high-pressure combined extraction technology; and thus, the extraction method of the common bletilla tuber extract is a green low-temperature extraction technology. The whitening and beautifying porridge with the common bletilla tuber extract disclosed by the invention is free of side effects; being frequently eaten, the porridge is capable of scavenging excessive free radicals in the human body, inhibiting tyrosinase activity, reducing melanin precipitation, as well as coordinating the intestines and the stomach so as to achieve long-lasting natural whitening effects from inside tooutside.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to an extraction method of bletilla striata extract, whitening and beautifying porridge and a preparation method thereof. Background technique [0002] "Retaining color", "beautifying face" and "healthy skin" reflect people's continuous pursuit of beauty from ancient times to the present. However, the environmental problems that accompany the pace of social development have become a major obstacle on the way for people to pursue beauty. Long-term exposure of the skin to external harmful factors (ultraviolet rays, chemicals, etc.) can cause overexpression of tyrosinase in melanocytes, thereby promoting the production of melanin. The distribution of melanin in the dermis of the skin determines the depth of the skin color. Tyrosinase is a key enzyme in the synthesis of melanin, which can catalyze L-tyrosine to generate dopa, and dopa is gradually oxidized to genera...

Problems solved by technology

This prior art has the following disadvantages: ① the bletilla striata polysaccharide prepared by it has high-temperature operation, which causes the loss of some heat-sensitive active ingredients, low extraction yield of active ingredients, difficulty in separation and purification, and long extraction time; ② its purpose It is used in cosmetics, but only by using cosmetics, it is impossible to achieve a long-lasting whitening effect. Only by combining internal conditioning can a long-lasting whitening effect be achieved from the inside out, and the concept of this invention has not been seen in the food research and development of diet-porridge reveal
