The present invention relates to a deodorant composition for sulfides, which comprises (A) a polyphenol or a polymer thereof and (B) sodium percarbonate or hydrogen peroxide.

Deodorant composition for sulfides

The invention provides a preparation method of cyaniding-3-O-glucoside chloride. Specifically, the method comprises the steps of: subjecting purple crops as the raw materials to an extraction with an extract of ethanol water solution with a volume fraction of 30-80% and a pH value of 1-4, leaving the obtained anthocyanidin crude extract to an ultrafiltration treatment through an ultrafilter membrane with a molecular weight cut-off of 1000-5000 D, and freeze drying the filtrate so as to obtain filtrate dry powder with a molecular weight less than 1000-5000 D, preparing a column-loading solution of 0.05-5wt% with the filtrate dry powder and water, purifying the filtrate dry powder preliminarily on a gel chromatographic column, conducting elution and collecting the eluent located at a position of 520nm and with an absorption peak, and reserving fractions containing cyaniding-3-O-glucoside chloride; purifying the fractions containing cyaniding-3-O-glucoside chloride further with preparative HPLC (high performance liquid chromatography), and collecting cyaniding-3-O-glucoside chloride absorption peaks. According to the invention, by improving the conditions and operations of extraction separation and purification, sugar, protein, other types of anthocyanin and flavonoid pigments in extracts can be effectively removed. Meanwhile, with simple steps and safe reagents, the method of the invention is beneficial for obtaining high purity cyaniding-3-O-glucoside chloride products.

Method for extracting cyanidin from black bean peel

The invention relates to a production process for preparing anthocyanin and pectin by black soya bean hull, which relates to a process for preparing anthocyanin and pectin. The production process includes steps of 1, pretreating raw materials; 2, extracting; 3, filtering; 4, adsorbing; 5, column washing; 6, eluting; 7, concentrating effluent; 8, drying the effluent; 9, centrifuging eluent; 10, concentrating pigment liquid; and 11, atomizing and drying the pigment liquid. By the production process, pectin in the black soya bean skin can be separated and purified when anthocyanin in the black soya bean hull is extracted, and anthocyanin high in healthcare value and pectin which is functional components can be obtained at the same time; utilization of black soya bean hull is improved greatly and additional value thereof is improved as well. Meanwhile, products have high extraction rate and purity and few impurities and the like by the aid of dynamic extraction, twice filtering and high-speed centrifuging.

Merr) product is provided, wherein the black soybean product is the seed coats of black soybean or an alcoholic extract of black soybean or seed coats thereof

Use of black soybean for treating ophthalmic diseases

Methods for preparing black soybean hull extracts and uses thereof. The methods can comprise: (1) extracting crushed black soybean hull with aqueous solution containing enzyme and filtering the extracted liquid; (2) ultrafiltration of the extract liquid with an ultrafiltration membrane; (3) absorbing the ultrafiltration liquid with an absorption resin or an ion exchange resin, and elution with ethanol to obtain purified extract liquid; (4) concentrating the purified extract liquid under vacuum; (5) spray drying the concentrated liquid. The extract can contain: 10-45% of cyanidin, 10-25% of catechin, and 40-80% of OPC, and with a total polyphenol content as high as 70-100%. The extract can be used for preparing drugs or food containing antioxidants, or used for improving metabolic syndrome or eyesight.

Black soybean hull extract, method for obtaining, and use thereof

The invention relates to a producing method of a black soya husk extract and the application thereof. The method comprises: (1) extraction step: digesting the finely milled black soya husk extract by the water solution containing the enzyme, filtering the extract and getting the filtering medium; (2) hyperfiltration membrane filtering step: filtering the filter medium by the hyperfiltration membrane; (3) resin separation step: adopting the resin absorption or ion-exchange resin absorption and further doing the elution treatment and getting the purified extract liquid; (4) condensation step: condensating in vacuum and getting the condensated liquid; (5) spraying and drying step: processing the spraying and drying to the condensation liquid and getting the black soya husk extract. The extract comprise: 10-45 wt.% of the cyanidin, 10-25 wt.% of the catechin, 40-80 wt.% of oligoprotoanthocyanidin and even 70-100 wt.% of the total polyphenol. The extract is used to prepare the medicine or food for improving the metabolic syndrome and the eyesight belonging to antioxidant.

Black soybean seedcoat extract and its extracting method and application

A process for preparation and use of black soybean hull (BSH) extract, The process comprise steps of: ( 1) extraction: extracting pulverized BSH with water containing an enzyme, filtrating the aqueous extract, yielding tine filtrate; (2) ultrafiltration: ultrafiltrating the filtrate with a ultrafiltration membrane* yielding the ultrafiltrate; (3) resin separation: adsorbing the ultrafiltrate onto an adsorption resin or ion exchange resin, eluting with ethanol, yielding purified liquid extract; (4) concentration: concentrating the extract in vacuo, yielding the concentrate; and (5) spray drying: spray drying the concentrate, yielding the BSH extract. The extract comprises 10 to 45% of scabiolide, 10 to 25% of catechin, and 40 to 80% of oligoproanthocyanidin, the amount of total polyphenol being up to 70 to 100%. The extract may be useful in preparation of medicaments or foods of the type of antioxidants, Tor ameliorating metabolic syndrome,, or for improving eyesight.
