Abstract

The invention discloses an amidation mesona chinensis benth glue and a preparation method thereof. The amidation mesona chinensis benth glue is prepared by adopting the following steps: adopting a mesona chinensis benth glue as a raw material, adopting an ammonia alcohol solution comprising ammonia water and isopropanol as an amidation reagent, carrying out an amidation reaction of the ammonia alcohol solution and a mesona chinensis benth glue aqueous solution for 95-125 min, and carrying out centrifugation on the obtained reaction solution; placing the obtained precipitate in 3-5 times by volume of a hydrochloric acid-isopropanol mixing solution, stirring for 10 min, carrying out vacuum suction filtration, washing, drying at a temperature of 105 DEG C, and grinding to obtain the amidation mesona chinensis benth glue. The preparation method comprises two steps such as solution preparation and amidation mesona chinensis benth glue preparation. According to the amidation mesona chinensis benth glue, the defect that the single mesona chinensis benth glue can not form a gel and can form a gel through interaction with starch is changed, a gelation performance of the mesona chinensis benth glue is changed, and the single mesona chinensis benth glue can form the gel.

Description

technical field [0001] The invention relates to amidated jelly gum and a preparation method thereof, belonging to the field of food processing technology. Background technique [0002] Jelly jelly gum is a functional ingredient with the most economic value in jelly jelly, and its content accounts for about 20% of the weight of dry leaves of jelly jelly. It is a unique type of food glue with local characteristics in my country. In terms of food processing, the processing method is relatively simple, mainly to make traditional jelly jelly, jelly tea, beverages, etc., but the deep processing of jelly grass is rare, and jelly jelly gum cannot form gel alone, only interact with starch. Form a gel. Contents of the invention [0003] The purpose of the present invention is to change the defect that the above-mentioned gelatin jelly gum cannot form a gel alone, and only interacts with starch to form a gel, and provides a method for making the grass jelly gum to form a gel alone b...
