Embodiment Construction

[0022] The crude extract powder of Camellia oleifera cake with a tea saponin content of 40% is purchased from the market, and diluted with water to a crude product solution with a tea saponin content of 1% (g / V), and the solution is brown.

[0023] Add content 1% (g / v) crude product tea saponin solution 250mL in 3 beakers respectively, wherein No. 0 is blank control, No. 1 is to add 3% (75mg) by LiAH 4 and NaHSO 4 The decolorizing agent prepared according to the mass ratio of 3:1 was reacted for 2 minutes, and No. 2 was added with 5% (v / v) hydrogen peroxide to decolorize the sample at 60°C for 30 minutes. The decolorizing effect is shown in figure 1 .

[0024] It can be seen from the experiment that the decolorization effect of this decolorizing agent is obviously better than that of the traditional hydrogen peroxide decolorization method. Experiments have found that if the two decolorizers are continued to be added in a certain proportion, the decolorization effect will sti...

Abstract

The invention discloses a method for decoloring crude tea saporin, which comprises the steps of adding a compound decolorant into a solution of crude tea saporin and reacting for 2 minutes at room temperature with stirring, wherein the compound decolorant is prepared by mixing metal complex hydride and acid accumulator sulfite in a mass ratio of 3:1-10:1, and the adding amount of the compound decolorant is 1 to 5 percent of the mass of solute in the solution of crude tea saporin. The decolorant is only reacted with polyphenol and flavone pigment components in the crude tea saporin to realize the decoloring function; and the surface activity of the decolorized tea saporin such as wetting, emulsification, foaming and foam stability is not influenced.

Description

1. Technical field [0001] The invention relates to a deep processing of agricultural by-products, in particular to a decolorization method of crude tea saponin. 2. Background technology [0002] Tea saponin (C 30 h 50 o 26 ) is a pentacyclic triterpenoid extracted from Camellia oleifera cake. Its basic structure is composed of saponins, sugars and organic acids. It has the properties of emulsification, dispersion, wetting, decontamination, foaming, and foam stabilization. It is a natural non-ionic surfactant with excellent performance. The aqueous solution of tea saponin produces honeycomb foam after being shaken, with strong foaming power and long-lasting foam, and is not affected by water hardness. It can be used in the development of various daily chemical products such as detergents and cosmetics. Tea saponin is also an excellent bioactive agent, which has various biological activities, such as hemolysis, anti-osmosis and anti-inflammatory, phlegm and cough relief, a...
