Soapberry saponin solution containing clear and stable compounds and preparation method thereof

Abstract

The invention belongs to the field of preparation of plant extraction solutions and in particular relates to a soapberry saponin solution containing clear and stable compounds and a preparation method thereof. The preparation method comprises the following steps: (1) adding a compound clarifying agent into an enzymolysis saponin extraction solution of soapberry peel and leaving the enzymolysis saponin extraction solution to stand for 30-60 min; (2) adding a compound antioxidant into the saponin extraction solution, heating to 90-100 DEG C and preserving the heat for 30-40 minutes; (3) cooling the saponin extraction solution to the room temperature, sealing, leaving the saponin extraction solution to stand for 2-4 hours, and extracting a supernatant solution by virtue of a siphon method; (4) filtering the supernatant solution by using a kieselguhr filter to prepare a primary clarification solution; (5) centrifuging the primary clarification solution and adding clear and stable compounds to prepare the clear and stable soapberry saponin solution. The enzymolysis extraction solution of soapberry peel is clear after being subjected to treatment of the method; meanwhile, the enzymolysis extraction solution is stable in performance and color and can be further processed into washing products.

Description

technical field [0001] The invention belongs to the field of preparation of plant extracts, in particular to a sapindus saponin solution containing a clear and stable compound and a preparation method thereof. Background technique [0002] The fruit of the natural plant Sapindus japonica can be obtained by artificial drying and peeling to obtain pure peel. Sapindus fruit peel contains triterpene saponins such as Sapindus saponin, which can be used to make "natural pollution-free detergent" for daily washing. There are many kinds of extraction methods of sapindus saponins, such as water extraction, microwave extraction, enzymatic hydrolysis and so on. Obstructed by the fibrous tissue of the plant cell wall, the extraction efficiency of Sapindus sapindus was not high when water extraction and microwave extraction were used. The enzyme has high efficiency and specificity, which can change the plant cell wall to varying degrees, thereby changing the permeability of the cell wa...

Problems solved by technology

[0003] However, because the addition of cellulase changes the permeability of the cell wall, the extract contains many other ingredients besides the active ingredients that need to be extracted. Even after conventional filtration, the extract will still be unclear and unstable. phenomenon, which affects the further processing and use of the extract

[0004] However, it is difficult for general clarifiers to control the appropriate degree of clarification. Either the dosage is too low to cause incomplete clarification, or the dosage is too high to cause too much loss of pigments and nutrients; Turbidity or precipitation, that is, post-turbidity and post-precipitation, so it is difficult to obtain a clear and stable Sapindus saponin solution
