Abstract
The invention discloses a Dictyophora indusiata water extract and a preparation method and application thereof. The preparation method comprises the following steps of: (1) mixing Dictyophora indusiata powder and deionized water, and performing ultrasonic extraction to obtain an extracting solution; (2) standing and precipitating the extracting solution, and filtering to obtain a recovered solution; (3) concentrating the recovered solution to obtain a concentrated solution; and (4) adding dextrin into the concentrated solution, stirring uniformly, and freeze-drying to obtain a product. The preparation method is easy to operate and is low in production cost; the obtained Dictyophora indusiata water extract is high in purity and high in yield; the Dictyophora indusiata water extract can be powdered easily, and is light yellow or yellow; and a cosmetic product prepared by using the Dictyophora indusiata water extract has a remarkable anti-aging effect and a more remarkable moisturizing effect.
Description
technical field [0001] The invention relates to a water extract of bamboo fungus and its preparation method and application, in particular to a moisturizing and anti-aging active ingredient in bamboo fungus, its preparation method and application. Background technique [0002] Dictyophora indusiata is a fungus of the genus Dictyophora in the family Phallaceae, also known as bamboo fungus, bamboo ginseng, and gauze fungus. It is a precious dual-purpose fungus with both edible and medicinal values. In my country, it is mainly distributed in Yunnan, Sichuan, Hunan, Fujian and the three northeastern provinces. [0003] Dictyophora is a kind of rare edible fungus, which is rich in a variety of high-quality plant nutritional proteins. It has high protein content and contains a complete set of amino acids that make up protein. Among them, the content of essential amino acids accounts for more than 1 / 3 of the total amino acids, exceeding that of grains and some meats. Glutamic acid ...
