Compound sweetening agent and preparation method thereof

Abstract

The invention relates to the technical field of sweetening agents and preparation methods thereof and particularly relates to a compound sweetening agent and a preparation method thereof. The compoundsweetening agent is prepared from the following chemical components: 97-99% of saccharose, 0.25-1.5% of L-arabinose, 0.1-0.75% of xylose and 0.4-1.2% of water. The preparation method of the compoundsweetening agent comprises the following steps: mixing L-arabinose extracted after processing sugar cane and sugar beet and washed and granulated sugar, and drying to prepare the compound sweetening agent. The compound sweetening agent is moderate in particle size and is in line with the usage habits of the consumers; through the compound sweetening agent, the consumers can obtain the sweet tastesimilar to that of saccharose during eating; the absorption to the saccharose of the human body is also reduced; multiple functions of reducing blood sugar, preventing obesity and improving diabetic symptoms are achieved; meanwhile, the compound sweetening agent is simple in preparation process and low in production cost, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of sweeteners and preparation methods thereof, and relates to a compound sweetener and a preparation method thereof. Background technique [0002] Existing L-arabinose belongs to the five-carbon aldose, and widely exists in fruit, rice, wheat and other coarse grain husks, larch wood, corn husks, beetroot, and gum arabic. L-arabinose is an important pharmaceutical intermediate. In recent years, it has been found that L-arabinose can inhibit the absorption of sucrose in the gastrointestinal tract, making it widely promising in weight loss and diabetes control. The specific health care of the Japanese Ministry of Health and Welfare In the food list, L-arabinose has been listed as a special health food additive for regulating blood sugar, and the American Medical Association has also listed L-arabinose as a nutritional supplement or non-prescription drug for anti-obesity agents. [0003] In May 2010, the Minist...

AI Technical Summary

Problems solved by technology

Due to the small amount of added auxiliary materials, the physical stirring method is easy to mix unevenly

In addition, since the crystal particles of L-arabinose and xylose are much smaller than those of white sugar, long-term shelf life will cause small crystals to separate from physically mixed products, resulting in uneven L-arabinose or xylose content

If xylose or L-arabinose syrup is directly added to the sucrose solution, sucrose will preferentially crystallize during the crystallization process, and there will be different crystal sizes. When the addition ratio of xylose or L-arabinose is small, there will still be mixed Uneven situation

In addition, it is reported that high-purity L-arabinose is dissolved and sprayed directly on white granulated sugar. Although the problem of uneven mixing is solved, it cannot be crystallized automatically, and the granulation process needs to be increased. The particle diameter is large and does not show crystal shape. , does not conform to consumers' consumption and use habits of commonly used white sugar
