Problems solved by technology

[0003] At present, there are few domestic and foreign reports on the extraction, separation and purification of sapindus saponin, and there are less than 10 domestic manufacturers of sapindus saponin. Their products generally have low saponin content, high sugar content, easy caking, Defects such as deep color, while the solution is opaque after the product is dissolved in water, and there are a lot of flocculent substances, these problems seriously restrict the quality and application of the product

Abstract

The invention discloses desugared and decolored soapberry saponin and a preparation method thereof. The preparation method comprises the following steps of (1) extracting crushed soapberry peels and an extraction solvent at a mass ratio of 1:(2-6) for three times, and combining the three extracted solutions; (2) filtering the combined liquid by a platy frame filter, and performing microfiltration on the liquid filtered by the platy frame filter by a microfiltration device; (3) after the microfiltration permeated liquid passes through a macroreticular resin column, eluting with deionized water and ethanol water with the volume percentage of 40 to 95 percent sequentially, and collecting an ethanol eluent; (4) performing reduced pressure distillation on the ethanol eluent to recycle ethanol, further concentrating the obtained solution by nano-filtration or reverse osmosis, performing atomization drying on the concentrated liquid, powdering, and granulating; and (5) finally decoloring the liquid by use of supercritical CO2, thus obtaining the decolored soapberry saponin.

Description

technical field [0001] The present invention relates to a kind of desugaring and decoloring sapindus sapinsin and preparation method thereof, specifically a kind of desugaring and supercritical CO 2 A method for preparing high-quality sapindus saponins by decolorization. Background technique [0002] Sapindus saponin is a natural non-ionic surfactant, the main active ingredients are triterpene saponins (I), sesquiterpene glycosides (II), fatty oil and protein. It not only has strong decontamination and cleaning ability, but also has the advantages of removing heavy metals, antibacterial and whitening, softening skin, removing freckles and acne, and preventing and treating skin diseases. At the same time, it has no irritation to human skin, no toxic side effects, and is easy to biodegrade. It can be used to make "natural pollution-free detergent", and can be widely used in glass, tableware, car cleaning, as well as beauty, shower, shampoo, skin care Such as daily and indust...
