Producing process for extracting hydrolytic drying materials and starch by yellow ginger

Abstract

The invention relates to a production process of extracting and hydrolyzing dry matter of turmeric and starch. The process of the invention is as follows: turmeric is cleaned, pulverized, ground, mechanically separated from pulp and slag, starch is recovered from slurry water, suspension and slag after starch precipitation are fermented, acid hydrolysis is used to extract the hydrolyzed dry matter of turmeric. The present invention uses mechanical separation technology to separate and extract starch in the process of extracting and hydrolyzing dry matter of yellow ginger, which not only improves the yield of saponin, but also comprehensively utilizes starch, reduces environmental pollution, has the advantages of simple operation, low production cost, and is suitable for industrialization Production and other characteristics, especially the in-depth research on the edible value of starch, the turmeric vermicelli, vermicelli and jelly made from it have increased the added value, opened up a huge market for turmeric starch, and have great promotion and application value.

Description

technical field [0001] The invention belongs to the field of phytochemical engineering, in particular to a production process for extracting hydrolyzed dry matter and starch from turmeric. Background technique [0002] Turmeric, also known as Dioscrea shield leaf and fire vine root, is a unique species in my country and is a wild herbaceous vine of the genus Dioscrea (Dioscrea.L). After nearly half a century of research on the biological characteristics and active ingredients of turmeric, it has been shown that the rhizome of turmeric contains (on an absolute basis) 1.1-16.5% diosgenin, 45-50% starch, 40-50% fiber and bio Alkali and other active substances. Among them, turmeric saponin content is the highest in the turmeric that grows from the Wudang Mountains to the southern foot of the Qinling Mountains. Dioscin has hemolytic, lipid-lowering, antibacterial, anti-inflammatory effects, and is a chemical raw material for the synthesis of steroid hormone drugs. Steroid horm...

AI Technical Summary

Problems solved by technology

Due to the large investment, poor wine market and poor economic benefits of enterprises, this process is difficult to popularize and apply.

[0007] The third is that some researchers first extracted turmeric starch and hydrolyzed the slag to extract saponin. Due to the decline in the recovery rate of saponin, it has not been popularized and applied.

[0008] The fourth is Hubei Yunxi Pharmaceutical and Chemical General Factory, which uses turmeric starch to produce citric acid, and has achieved good results, but the cost is still too high, so it has not been popularized and applied.

However, the amount of waste water after turmeric hydrolysis is very large, glucose only accounts for about 2% in waste water, and the production cost is relatively large

[0010] Sixth, there are currently research units that have used the separation method to extract saponin, but have not used starch

[0011] Although the comprehensive utilization of turmeric starch has attracted attention from all walks of life, it has not found a method with low processing cost, high saponin recovery, and suitable for large-scale industrial production of enterprises.
