Problems solved by technology

The above-mentioned process products have high purity, but the process is complex, the utilization of raw materials is not high, and it is difficult to realize industrialization
CN101979400A and CN101942355A disclose that crude tea saponin and tea seed polysaccharides are obtained by water extraction and alcohol precipitation or alcohol extraction and water precipitation, and then purified by macroporous resin to obtain high-purity tea saponin; the production process of this process is complicated, and flavonoid glycosides cannot be obtained Utilization, water consumption and energy consumption are large, the process cycle is long, and it is not suitable for industrial production.
[0005] At present, there is no production process for simultaneously extracting and purifying tea saponin, flavonoid glycosides and tea polysaccharides from tea seed cake

Embodiment 1

[0025] Example 1 Extraction of tea saponin, tea seed flavonoid glycosides, and tea polysaccharides:

[0026] (1) Take 1kg tea seed cake and crush it into 40 mesh powder;

[0027] (2) Add the tea seed cake to 8 times the mass of deionized water, soak for 0.5 hours, put the mixed liquid into the flash extractor, stir and extract for 40 seconds, and then collect the filtrate after centrifuging at 4000rpm; The crude extract that the second gained filtrate merges, and filter residue is dried to obtain by-product;

[0028] (3) acid adjustment: adjust the pH value of the crude extract to 4 with hydrochloric acid;

[0029] (4) Preparation of tea polysaccharide products with macroporous resin: Pass the acid-adjusted extract through the pretreated macroporous resin, wash the resin with deionized water until the effluent is colorless, adjust the pH value of the effluent to 3, and stir at room temperature for 2 hours , centrifuged at 8000rpm to remove insoluble matter, and the filtrate ...

Embodiment 2

[0033] Follow the steps below to extract tea saponin, tea seed flavonoid glycosides and tea polysaccharides,

[0034] (1) Crush 10kg tea seed cake into 100 mesh powder;

[0035] (2) Add the tea seed cake to 12 times the mass of deionized water, soak for 1 hour, put the mixed liquid into the flash extractor, stir and extract for 80 seconds, collect the filtrate after filtering through filter paper; repeat the obtained filter residue once, and obtain The crude extract that filtrate merges, and filter residue is dried to obtain by-product;

[0036] (3) acid adjustment: adjust the pH value of the crude extract to 5 with citric acid;

[0037] (4) Preparation of tea polysaccharide products with macroporous resin: Pass the acid-adjusted extract through the pretreated macroporous resin, wash the resin with deionized water until the effluent is colorless, adjust the pH value of the effluent to 4, and stir at room temperature for 3 hours , filter paper to remove insoluble matter, and ...

Embodiment 3

[0041] Follow the steps below to extract tea saponin, tea seed flavonoid glycosides and tea polysaccharides,

[0042] (1) Crush 50kg of tea seed cake into 80-mesh powder;

[0043] (2) Add oat flour to 10 times the mass of deionized water, soak for 1 hour, put the mixed liquid into the flash extractor, stir and extract for 60 seconds, and collect the filtrate after filtering with filter paper; repeat the obtained filter residue twice, each time the obtained filtrate The combined crude extract and the filter residue are dried to obtain by-products;

[0044] (3) acid adjustment: adjust the pH value of the crude extract to 4.5 with citric acid;

[0045](4) Preparation of tea polysaccharide products with macroporous resin: Pass the acid-adjusted extract through the pretreated macroporous resin, wash the resin with deionized water until the effluent is colorless, adjust the pH value of the effluent to 3.5, and stir at room temperature for 2.5 hours , centrifuged at 8000rpm to remo...

Abstract

The invention belongs to the technology field of processing and utilization of agriculture product, and relates to a comprehensive extracting method of tea saponin, tea seed flavonoid glycoside, and tea polysaccharide. The method comprises following steps: (1) grinding raw materials; (2) extracting; (3) adjusting acidity; (4) preparing a tea polysaccharide product with a macro-porous resin; (5) preparing tea seed flavonoid glycoside; (6) preparing tea saponin. The method is capable of simultaneously extracting three effective components of tea saponin, tea seed flavonoid glycoside, and tea polysaccharide, and improves the quality of crude tea saponin; adopts an instant extracting technology, has the characteristics of rapidness, completeness, and high efficiency; adopts a macro-porous resin to purify tea saponin, has the advantages of simple technology, low production cost, and high product purity; furthermore, organic solvents are not used during the whole production process , and thus the method is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of processing and utilization of agricultural products, and relates to a comprehensive extraction method of tea saponin, tea seed flavonoid glycosides and tea polysaccharides; in particular, a method for simultaneously extracting tea saponin, tea seed flavonoid glycosides and tea polysaccharides. The method has the advantages of simple process, low production cost, high product purity and good quality. Background technique [0002] Camellia oleifera is a unique oil tree species in my country. According to statistics, camellia oleifera seed resources in my country are extremely rich. At present, the annual output of camellia oleifera seeds in my country is about 1.2 million tons, and the tea seed cake produced after oil extraction is about 600,000 tons. Most of the tea seed meal is used as pond clearing agent, fertilizer and fuel, or even discarded; The research on resource utilization of seed cake, extractin...
