Investigation of Barcelona and Du Chilly filbert nuts. I. Chemical study of Barcelona and Du Chilly filbert nuts and oils

Summary Barcelona and Du Chilly fibert nuts have been analyzed for their principal constituents. The characteristics of the oils obtained by solvent extraction and by cold expression have been determined and their fatty acid composition has been ascertained. Most of the chemical and physical characteristics of the oils as determined in this laboratory agree well with values previously reported by other investigators on European varieties. However, our study of the oil components shows a considerable difference in fatty acid composition.
