Specifications and Other Information of Our L-Rhamnosidase CAS 37288-35-0
The product is prepared by submerged fermentation of Aspergillus niger. a-L-rhamnosidase (EC188.8.131.52) is a specific glycoside hydrolase that acts on a-1,2, a-1,3, a-1,4, a-1,6 and a 1-linked glycosidic bonds. and a 1-linked glycosidic bonds, hydrolysing the non-reducing a-L-rhamnosidic bond bound to the end of the substrate, while releasing rhamnose and the corresponding ligand. a-L-rhamnosidase acts synergistically with β-glucosidase to specifically hydrolyse some natural products such as naringin, rutin and quercetin to remove bitterness.

1.Plant extracts can replace acid and alkaline hydrolysis, reducing environmental pollution and increasing the yield of active ingredients;
2.It is used to remove the bitterness of naringin from citrus juice and to hydrolyse naringin into rhamnose and tangerine glycosides, of which tangerine glycosides are important precursors for the industrial production of sweeteners.
3.Acts on terpene glycosides to improve the aroma composition of grape juice, wine and beverages, etc. and to produce food additives;
4.It can hydrolyse naringin and lemon bitterness in fruits of the Rutaceae family to remove bitterness from the juice, thus making the juice sweet and sour with a pleasant taste;
5.It can improve the bioavailability of flavonoids and can be used in the production of functional drinks;
6.Catalytic hydrolysis of rutinoside for the targeted biosynthesis of isoquercitrin, which could be a hot new drug compound;
7.Catalyzes the synthesis of naringin, which can be used as a raw material for a variety of pharmaceuticals.
