Abstract
`Concord' grape skin contained 0.32% lipids, while the pulp contained 0.10%. Glycolipids predominated in both skin and pulp, accounting for respectively 53.6 and 66.9% of lipid content, neutral lipids represented 40.2 and 24.8%, and phospholipids contributed 6.2 and 8.3%. The major fatty acids of the skin were stearic, palmitic, and arachidic in the neutral lipids, while linolenic and pelargonic acids predominated in the glycolipids. The most prevalent fatty acids of phospholipids were palmitic, linolenic and linoleic. Neutral lipids of the pulp were high in palmitic and stearic acids. Linolenic acid was the major fatty acid in the glycolipids, with pelargonic and palmitic acids also contributing. Phospholipids were high in palmitic and linoleic acids.
