Abstract

The invention relates to a green composition taking stevioside as a matrix. The green composition comprises the following components in parts by weight: 65-80 parts of stevioside, 20-25 parts of sugarcane powder and 10-20 parts of cyclodextrin. The stevioside in the composition disclosed by the invention contains a variety of amino acids, VB (vitamin B), beta-carotene and other nutritional ingredients, and the sugarcane powder contains three ingredients, namely sucrose, fructose and glucose, as well as a variety of essential amino acids for human bodies, and can be compounded with the stevioside to obtain excellent taste; in addition, the cyclodextrin is added, so that and the unfavorable bitter aftertaste of the stevioside can be relieved, and the stability of the composition can be obviously enhanced; and the green composition has the advantages of low calorie, abundant amino acids and strong stability, can be used for substituting sugar, saccharin and other various chemically synthesized sweeteners, meets the diet requirements of modern people, and can be widely applied in foods, drinks, pickled products, pharmaceutical preparations and other industries.

Description

technical field [0001] The invention belongs to the technical field of food, and relates to sweeteners, in particular to a green composition with stevioside as a base and a preparation method thereof. Background technique [0002] Excessive intake of high-calorie sugars can easily cause dental caries, obesity, hyperglycemia and other diseases. This is a common phenomenon all over the world, and it has a tendency to spread from developed countries to developing countries. In recent years. As people's health awareness continues to strengthen, consumers pay more and more attention to the problem of sugar intake, and new consumption concepts are gradually forming. Natural, green, healthy, nutritious and health-care diet trends are becoming a new diet trend. Therefore, the use of various low-calorie high-intensity sweeteners in food to replace high-calorie sweeteners and the production of low-sugar products have become research and development hotspots for major food companies. ...
