Problems solved by technology

[0006] In order to solve the shortcomings in the above-mentioned background technology, the present invention provides a clean production and processing method of turmeric, which replaces rough processing with refined processing, replaces a single product with diversified products, and replaces traditional fermentation with modern membrane concentration technology and enzymatic hydrolysis technology. The technical route of acid hydrolysis technology can not only greatly reduce processing costs, increase the added value of products, but also realize zero discharge of process sewage, so as to completely solve the pollution problem in this industry

Embodiment

[0046] 1. The raw material of turmeric is cleaned to ensure that the quality of the process products, especially the turmeric starch used as food, meets the requirements of relevant regulations and standards;

[0047] 2. Crushing, the particle size is 4mm, to ensure that the product is suitable for the subsequent processing requirements;

[0048] 3. Ultrasonic-assisted refining to break the walls of turmeric tissue cells, with a particle size of 0.3 mm, in order to meet the requirements of the subsequent process for the separation of lignocellulose, turmeric starch and saponin-containing slurry;

[0049] 4. Press 150bar to separate lignocellulose and other components to obtain lignocellulose products. The process requirements and parameter settings must ensure that the saponin loss rate is lower than the process limit;

[0050] 5. Centrifuge at a speed of 1000 rpm to separate the starch from the feed liquid and form a turmeric starch product, which meets the relevant product s...

Abstract

The present invention relates to a clean production processing method of turmeric. Said method includes the following steps: cleaning turmeric raw material, pulverizing, ultrasonic auxiliary grinding, pressing, centrifugal separation, first membrane concentration, hydrolysis, press filtration, extraction, neutralization and secondary membrane concentration.

Description

1. Technical field: [0001] The invention relates to a turmeric production and processing method, in particular to a turmeric clean production and processing method, which is a multidisciplinary comprehensive technology spanning food processing, extraction of pharmaceutical intermediates and environmental protection engineering. 2. Background technology: [0002] Turmeric is an economic crop with extremely high medicinal value. Its scientific name is shield leaf Dioscorea, which is a genus of Dioscorea in the Dioscoreaceae family. The rhizome of turmeric contains diosgenin, which can be used as a precursor to synthesize more than 290 drugs with anti-inflammatory, contraceptive, and cardiovascular diseases. It is an important pharmaceutical intermediate for the synthesis of steroid hormones. Known by the pharmaceutical industry as "medicinal gold" and "the mother of hormones", the global output value of pharmaceutical products extended by saponin is about 20 billion US dollar...
