Abstract

The present invention relates to a process for obtaining polysaccharides from jatoba seeds, comprising the steps of: a) seed processing (dry process); b) aqueous extraction at 1% to 5% of powder mass per volume, preferably 2% of powder mass per volume; c) precipitation with ethanol 969GL using 1 to 3 times the aqueous extract volume; d) press filtration of the precipitate obtained in (c); e) solublization of the polysaccharides obtained in step (d) with water; and f) drying the polysaccharides obtained in step (e). In another embodiment, the present invention relates to a cosmetic composition containing polysaccharides obtained according to the process defined above and to the use of said polysaccharides.

First claim

The invention claimed is:

1. A process for obtaining polysaccharides from jatoba ( Hymenaea courbaril ) seeds, the process consisting of:
a) treatment of the seeds by using microwave for separating the coats;
a1) grinding the treated seeds to obtain a powder;
b) aqueous extraction at 1% to 5% of the powder mass per volume of the treated seeds obtained in step a) at a temperature of 70° C. for 4 hours;
b1) separating the polysaccharides after the step of aqueous extraction, said separation being a centrifugation carried out at 4100 RPM for 15 minutes;
c) precipitation with ethanol 96° GL using 1 to 3 times the aqueous extract volume;
d) press filtration of the precipitate obtained in step (c);
e) solubilization of the polysaccharides obtained in step (d) with water; and
f) drying the polysaccharides obtained in step (e) by spray drying or by freeze drying,
wherein the seeds obtained in step (a) are free from coat components in inner parts of the seeds.

2. The process of claim 1 , wherein aqueous extraction in step (b) is performed at 2% powder mass per volume.
