Making method of fructus momordicae bitterant

Abstract

The invention discloses a making method of a fructus momordicae bitterant, and belongs to the technical field of natural product application. The method comprises the steps as follows: (1) pretreatment and percolation extraction of raw materials; (2) column chromatography; (3) decolorization; (4) concentration and drying of a decolorization solution; (5) crystallization and recrystallization. According to the method, acid addition for percolation extraction is adopted, a large amount of steam consumed by heating extraction is saved, emission of carbon dioxide is reduced, impurities, pigment and the like in an extract are greatly reduced, the adsorption capacity of effective ingredients in resin in the step of column chromatography is improved, the handling capacity of a decolorization column on the raw materials is improved, energy consumption is significantly reduced, the productivity efficiency is significantly increased, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to a preparation method of Luo Han Guo bittering agent, which belongs to the technical field of natural product application. Background technique [0002] In 2015, the planting area of ​​Luo Han Guo in Guangxi exceeded 60,000 mu, with an annual output of more than 30,000 tons of fresh fruit. The national planting area of ​​Luo Han Guo reached 120,000 mu, and the planting scale grew at a rate of 15% to 20% every year. Among them, 15% to 30% of Luo Han Guo cannot mature normally due to the influence of conditions such as the soil and climate of the planting place. This kind of mangosteen that cannot mature normally has a very bitter taste, but the total amount is very large, reaching more than 10,000 tons in total. However, Luo Han Guo extract manufacturers are also unwilling to process bitter fruits, because the sweetness and quality of plant extract products are affected after the bitter fruits are mixed with normal fruits for pr...

Problems solved by technology

[0006] The above research either obtained mogropicrin through n-butanol extraction and repeated column chromatography on silica gel, which is not suitable for large-scale industrial production; or it was transformed by adding hormone (ethephon), resulting in a high rate of bad fruit and hormone residues. , the operation is cumbersome, labor-intensive and site-occupied; or adding enzymes to transform the mogrosides in order to remove most of the bitter substances, but none of them can be completely transformed and removed, and the transformed mogrosides are non- Natural ingredients, also without the sweetness of natural ripe Luo Han Guo
