Abstract

The invention discloses functional food containing dry Malus toringoides and Malus transitoria leaves and Zea mays styles and stigma and a preparation method of the functional food. The functional food comprises raw materials in percentage by mass as follows: 20%-80% of the dry Malus toringoides and Malus transitoria leaves and 20%-80% of the Zea mays styles and stigma. According to the preparation method of the functional food, the dry Malus toringoides and Malus transitoria leaves and the Zea mays styles and stigma are pretreated, ethanol is added for reflux extraction, obtained filtrates are mixed, ethanol is recovered, extract is dispersed in hot water, left to stand and centrifuged, then precipitates are dried in vacuum, maltodextrin is added, a soft material is prepared, granulation,drying and pelletizing are performed, and total pellets are obtained. Study finds that the raw materials have synergy after being used concomitantly, and the functional food has remarkable effects ofreducing blood sugar and reducing blood lipid.

Description

technical field [0001] The invention relates to a functional food, in particular to a Russian-leaf corn silk functional food and a preparation method thereof. Background technique [0002] With the development of society and the advancement of science and technology, people's living standards continue to improve, and people's diet structure also changes accordingly. The intake of sugar, protein and fat continues to increase, while the amount of exercise is relatively reduced. High blood sugar, high blood fat Metabolic problems such as diabetes are on the rise, which has also exacerbated the incidence of diabetes, atherosclerosis, coronary heart disease, fatty liver and other diseases. For blood sugar and blood lipids, how to control them at normal levels is the key to preventing further development and deterioration of metabolic diseases. Therefore, effective control of blood sugar and blood lipid levels has become a problem that people need to pay attention to in their dai...
