Problems solved by technology

[0005] The disadvantages of the existing production methods: 1. These two processes are the main processes for making fenugreek seed glue at present. Because the hardness and brittleness difference of changing the seed coat, endosperm and cotyledons are not considered, the separation efficiency is low, and the endosperm is difficult to further purify Large, in comparison, the cost of processing galactomannan with guar beans as raw materials is much higher, and there is no competitive advantage
2. The cotyledon of fenugreek after degumming contains a considerable part of endosperm and seed coat, which is difficult to effectively separate, which brings great difficulties for the production technology research of developing downstream products with fenugreek cotyledon as raw material, which is not conducive to the development of fenugreek seeds. Comprehensive development and utilization
3. Using industrial film as raw material, through hydration, thickening, washing, drying and other processes, to prepare pure and high-viscosity rubber powder, the process is more and time-consuming, which increases the production cost

Abstract

The invention discloses a production method of fenugreek gum. The production method comprises the following steps of a, cleaning and winnowing seeds; b, adding inorganic salt in selected seeds according to a proportion of seed weight to inorganic salt volume of 1:(10-50), digesting, and filtering to eliminate a digestion solution; c, peeling and screening the filtered seeds to obtain seed kernels; d, drying and dehumidifying the seed kernels obtained in the step c, and controlling the water content to be 8-25 percent; e, separating endosperms of the seed kernels obtained in the step d from cotyledons of the seed kernels, and collecting the endosperms and the cotyledons; f, grinding the cotyledons obtained in the step e in ethyl alcohol to obtain ground fenugreek gum; and g, centrifuging, drying and grading the ground fenugreek gum obtained in the step f, and packaging a finished product. According to the production method, the process is simplified, and the quality of the fenugreek gum is improved.

Description

technical field [0001] The invention relates to a production method of fenugreek gum. Background technique [0002] Fenugreek seeds are composed of seed coat, endosperm and cotyledon, wherein the seed coat accounts for 10%-15% of the seed weight, the endosperm accounts for 35%-40% of the seed weight, and the cotyledon accounts for 45%-55% of the seed weight. The main component of endosperm is galactomannan, which has good water solubility, crosslinking and unique rheology. It has important uses in oil field drilling, feed manufacturing, aquaculture, food and medicine, etc. It is the only plant gum resource found in my country that can compete with imported plant gum, and the market demand is huge. [0003] After many years of technical research at the Nanjing Institute of Natural Wild Plants in China, according to the different physical properties of endosperm and cotyledons, the semi-wet method is used to separate and extract cougar gum. , film selection and screening, fi...
