Embodiment 1

[0019] Embodiment 1: a kind of preparation method of geniposide food antiseptic and fresh-keeping material, comprises the following steps:

[0020] (1) Prepare a geniposide solution with a concentration of 0.2-0.8g / mL;

[0021] (2) Prepare a copper sulfate solution with a concentration of 0.05-0.1g / mL;

[0022] (3) According to the mass ratio of copper sulfate and geniposide: 1:3~5, under the condition of 35°C~45°C, add the copper sulfate solution to the geniposide solution dropwise, stir while adding, and stir The speed is 40~60rpm;

[0023] (4) After the dropwise addition, cool and stand for 8 to 12 hours;

[0024] (5) Take the supernatant and purify it through a silica gel column, and the effluent is the purified solution;

[0025] (6) The purified solution is vacuum concentrated, crystallized, and dried to obtain the finished geniposide food antiseptic and fresh-keeping material, that is, geniposide-copper (II).

[0026] In this embodiment, in the process of adding the...

Abstract

The invention relates to a preparation method of geniposide food antiseptic and fresh-keeping materials. The method uses geniposide and copper sulfate as raw materials, that is, the copper sulfate solution is added dropwise to the geniposide solution, stirred while dropping, and the dropping is completed After that, let it cool and stand still, then take the supernatant and pass it through a silica gel column for purification, and the purified solution that flows out is concentrated and crystallized in a vacuum, and dried to obtain the finished geniposide food antiseptic and fresh-keeping material geniposide-copper (II) chelate. The present invention has the advantages: 1. Applying geniposide to the field of antiseptic and fresh-keeping of food expands the scope of use of geniposide, directly consumes more gardenia raw materials for agricultural materials, increases market demand for gardenia, and benefits gardenia sub-planter. 2. The geniposide food antiseptic and fresh-keeping material prepared by the method of the present invention can not only preserve food anti-corrosion and prolong the shelf life of food, but also meet the human body's demand for trace element copper.

Description

technical field [0001] The invention relates to a preparation method of a fresh-keeping material, in particular to a preparation method of a geniposide food antiseptic and fresh-keeping material. Background technique [0002] Geniposide is a product extracted and refined from the dried and mature fruit of Gardenia jasminoides of the Rubiaceae plant using high-tech production technology. Geniposide is an iridoid glycoside compound, all plums glucoside dehydroxygeniposide. Geniposide has many uses. Fermented under different conditions, it can be made into natural edible colorants gardenia blue and gardenia red. It is also a raw material drug for treating cardiovascular and cerebrovascular diseases, liver and gallbladder diseases, and diabetes. [0003] Yellow Gardenia is planted in Jiangxi, Hunan, Hubei, Guangdong, Guangxi, Sichuan, Chongqing, Fujian, Anhui, Zhejiang, Jiangsu, Yunnan, Guizhou and Henan. Planting gardenia jasmine is an effective way for farmers to adjust thei...
