Background technique

With the development of science and technology and people's awareness of physical health, it has been found that excessive consumption of sucrose can cause great harm to the human body. Nutritional survey found that although eating sugar may not directly lead to diabetes, long-term consumption of sweets will cause excessive insulin secretion, carbohydrate and fat metabolism disorders, causing environmental imbalances in the human body, which in turn may lead to a variety of chronic diseases, such as heart and brain. Vascular disease, diabetes, obesity, senile cataract, dental caries, etc. Therefore, sugar-free, low-calorie, pure natural sweeteners are becoming the trend of the times, and the market potential is also huge.

Siraitia glucoside V, also known as Luo Han Guo sweet glutinous rice (or Luo Han Guo sweet), is extracted from the special economic plant of Guangxi, Luo Han Guo. Its sweetness is 240 times that of sucrose, but its calorie is zero. Luo Han Guo is a dual-use plant with heat and heat. It has the effect of moistening the lungs, relieving cough and laxative, and has preventive effects on obesity, constipation and diabetes. As a food, it is safe and non-toxic, and can be safely eaten. However, after eating for a long time, there is a post-sweet taste in the tongue and mouth. Some of the aftertaste has bitterness and astringency, and the sweetness is not as good as sugar. Directly, people have an unpleasant eating experience. Therefore, even if there are several times the sweetness of sucrose, the application of sugar as a sweetener in daily life is greatly affected by the aftertaste and can only be used as food. Additives are used in small amounts in foods. Therefore, it is urgent to find a scientific and reasonable sweetener combination to modify and cover the aftertaste of mogroside, and to increase the application range of mogroside V.

CN 104256258A discloses a composition for a complex functional sugar, a refreshing tablet and a process for the preparation thereof, the composition comprising the following components by weight: 0.1 to 80% functional oligosaccharide, 0.01 to 20% high Sweetener, 0.1-80% sugar alcohol, 0.1-95% monosaccharide, 0.01-80% dietary fiber, 0.01-30% botanical efficacy ingredient. The preparation method of the refreshing tablet comprises the steps of: adding the compound functional sugar to water and swelling; adding the thickener to the water to dissolve and swell; mixing the compound functional sugar and the thickener, stirring in a constant temperature water bath, and standing still. The mixed colloid is obtained; the mixed colloid is cooled to room temperature, the flavor and fragrance are added; the mixture is allowed to stand after being mixed; the bubbles in the mixed colloid are removed; the mixed colloid is coated on the plexiglass plate; and the coated plexiglass plate is dried.
