USDA/ARS scientists have found a sap derived from the stem of frost grape, a native US species, that's both chemically and functionally similar to gum Arabic.
Frost grape, Vitis riparia, occurs throughout North America and typically grows as a woodland vine reaching up to 50 feet in length and 4 to 5 inches in diameter.
The scientists note the ease with which the frost grape polysaccharide can be extracted and rendered into a white powder, viscous liquid or clear gel.
Also, unlike corn fiber gum, another potential gum Arabic alternative, the frost grape polysaccharide doesn't require the use of costly, alkaline-based extraction methods.
The researchers are trying to nail down the actual function and seasonality of the polysaccharide in the frost grape plant itself.
Reporting in the August 2015 issue of the Journal of Agricultural and Food Chemistry, Price, together with plant physiologist Steven Vaughn and NCAUR colleagues, announced their discovery of a sap derived from the stem of frost grape, a native U.
It's strange nobody's looked at this before," says Vaughn of the scientific literature review they conducted on frost grape polysaccharide.
Price is impressed with the frost grape polysaccharide, noting the ease with which it can be extracted and rendered into a white powder, viscous liquid, or clear gel.
In the meantime, the researchers are trying to nail down the actual function and seasonality of the polysaccharide in the frost grape plant itself.
