Abstract

The present invention provides radix polygonati officinalis lactic acid fermented health-care drink and a preparation method thereof. The radix polygonati officinalis lactic acid fermented health-care drink is prepared by the following method: sugar is added into pre-treated extracted radix polygonati officinalis, lactic acid bacteria are used to conduct a fermentation, and then a fermentation product is filtered; or the pretreated radix polygonati officinalis is extract to obtain a radix polygonati officinalis extract, firstly, the radix polygonati officinalis extract is filtered, then the sugar is added, and the lactic acid bacteria are used to conduct the fermentation of the mixture; the obtained fermentation products by the two methods are respectively subjected to suction filtration, the filtered fermentation products are sterilized, and the sterilized fermentation products are cooled to obtain the lactic acid bacterium health-care drink. The radix polygonati officinalis is used as a main raw material, the lactic acid bacteria are applied in non-dairy products to conduct the fermentation, and the preparation method breaks a traditional pattern of using dairy products as the raw materials and fermenting by the lactic acid bacteria, does not contain blending links, and maximally saves nutrients in the radix polygonati officinalis. Besides, the health-care drink also has characteristics of lactic acid bacterium drinks, is also good in mouthfeel, sour, sweet and tasty, and has functions of cooling and refreshing body, and promoting salivation and quenching thirst.

Description

technical field [0001] The invention relates to the field of food fermentation, in particular to a lactic acid fermented health drink and a preparation method thereof, in particular to a Polygonatum lactic acid fermented health drink and a preparation method thereof. Background technique [0002] Polygonatum Polygonatum is more and more popular as an excellent nutritional tonic for nourishing, preventing dryness, reducing blood pressure and relieving heat, and its demand as a health food is much higher than that of the pharmaceutical industry. However, most of the processing of Polygonatum odoratum is now sun-dried or steamed into dry products of Polygonatum odoratum sticks or slices, which are mainly sold in the form of raw medicinal materials and processed decoction pieces, and the added value of the product is relatively low, so it should be strengthened The development of bamboo tonics, health drinks and health food is to increase the added value of Polygonatum odoratum ...
