Medicinal sweet potato Simon I leaf concentrated oral liquid and preparation method thereof

Abstract

The invention relates to a processing method of sweet potato leaves, and in particular relates to a medicinal sweet potato Simon I leaf concentrated oral liquid and a preparation method thereof, and belongs to the technical field of food beverage. The method is as below: a Simon I sweet potato leaf extract, a licorice extract and auxiliary materials are subjected to effective component extraction, filtering and vacuum concentration to prepare the oral liquid. The Simon I concentrated oral liquid has a brown appearance, no precipitate, content of soluble solid no less than 6.5 DEG Bri* (if added white granulated sugar, no less than 10.5 DEG Bri*), pH value of 4.3-5.0, microbial indicators in line with NY / 434-2007 Green Food Fruit and Vegetable Juice Beverage, and a shelf life up to 12 months. The method uses a modern high-tech means to process the Simon I sweet potato leaves into a functional food, so as to rationally use the valuable resource; therefore, the invention on the one hand can significantly increase economic benefit of potato growers, and on the other hand benefits human health undertaking.

Description

technical field [0001] The invention relates to a processing method of sweet potato leaves, in particular to a medicinal sweet potato Ximeng No. 1 sweet potato leaf concentrated oral liquid and a preparation method thereof, belonging to the technical field of food and drink. Background technique [0002] Simon No. 1 sweet potato was introduced from Brazil to Japan by Chinese-Japanese medical doctor Yang Tianhe in 1973, and was introduced from Japan to Shanghai, my country in 1982, and introduced to Xuzhou, Beijing, Hunan and other places in 1983. In the 1970s, Brazilian scholars Professor Zheng Ximeng and Dr. Yang Tianhe conducted research on the medicinal value of special sweet potato roots. Since 1984, we have carried out systematic introduction observation, high-yield cultivation, deep-processing products and research on health function of Simon No. 1 sweet potato. Sweet potato leaves are rich in protein, cellulose, vitamins (A, B1, B2, C), calcium, phosphorus, iron, sel...

Problems solved by technology

The only research report is about the development and component analysis of Simon No. 1 health drink in the 1990s. The research at that time used the stem and leaf of Simon No. 1 as the raw material, that is, the mixture of stem and leaf, and used fresh stem and leaf. The raw materials cannot be stored, and the production and processing season is limited; the product has obvious bad taste due to the use of fresh stems and leaves; in order to solve the problem of product clarification, additives are used; the added sugar solution comes from the fermentation of the remaining sugar solution of preserved fruit, which is very important for the quality Difficult to control

In short, in the existing research, the reports using the leaves as raw materials all use common sweet potato varieties; the research using Simon 1 as raw materials uses fresh stems and leaves as raw materials; and the processing methods use beating and atmospheric pressure cooking, This will bring bad taste to the product and difficulties in green protection; in addition, the packaging form of the product is a common canned or bottled beverage with a relatively thin concentration (or low active ingredient content)
