Researchers discover gene that controls melting point of cocoa butter
April 17, 2015
By Jeff Mulhollem April 16, 2015 UNIVERSITY PARK, PA. -- The discovery of a gene involved in determining the melting point of cocoa butter -- a critical attribute of the substance widely used in foods and pharmaceuticals -- will likely lead to new and improved products, according to researchers in Penn State's College of Agricultural Sciences.

Gene Involved in Determining the Cocoa Butter Melting Point Discovered
March 31, 2015
In plants, the conversion of stearoyl-ACP to oleoyol-ACP is catalyzed by a plastid-localized soluble stearoyl-acyl carrier protein (ACP) desaturase (SAD). The activity of SAD significantly impacts the ratio of saturated and unsaturated fatty acids, and is thus a major determinant of fatty acid composition. The cacao genome contains eight putative SAD isoforms with high amino acid sequence similarities and functional domain conservation with SAD genes from other species. The identification of the major SAD gene responsible for cocoa butter biosynthesis provides new strategies for screening for novel genotypes with desirable fatty acid compositions, and for use in breeding programs to help pyramid genes for quality and other traits such as disease resistance.
