Extraction, identification and biological properties of almond gum

摘要

The present invention relates to the separation of almond gum polysaccharide into soluble part ("PSGA") and hemicellulose part ("HGA") and compares their structures, biological activities and functional properties. The polysaccharide of almond gum was composed of 14.9% soluble fiber and 46.38% insoluble fiber. Several methods described in the literature can be segmentedDissolved and insoluble parts of rubber Polysaccharides in the insoluble fraction are usually defined as hemicellulose. These water-insoluble polymers are usually separated from plant materials by the use of alkaline solutions.Then neutralize and precipitate with ethanol. The functional and biological properties of these hemicelluloses have been widely described in the literature. In fact, these polymers are biologically active in most cases. Physical chemistry and / or functional properties of great interest and interest in the field of food and biotechnology, such as glucose carboxyalkanes extracted from pineapple resin and heterohydroxyalkanes extracted from palm resin. L'ObjecThe TIF of this study is to divide the polysaccharide of almond gum into insoluble hemicellulose and soluble polysaccharide ("PSGA"). The sugar composition and molecular weight of the two components were determined. The biological activity of these two polysaccharides componentsPSGA was evaluated by total antioxidant activity test, reducing power test, anti ABTS activity test and p-carotene bleaching inhibition activity test, and compared with synthetic antioxidant, BHA. The antibacterial, prebiological and antihypertensive activities of two polysaccharide fractions of almond gum (PSGA and HGA) were also tested.
