Constitution of the Deposit on the Inner Surfaces of Gin Roll Boxes

Abstract

Material which had accumulated on the inner surface of gin roll boxes during the ginning of immature bolls has been collected and subjected to chemical analysis. This deposit material, which was a dried, hard, dark-brown substance, has been shown to be about 25% protein and 8% lipid, the remainder being fuzz fibers, lint, and seed-coat fragments. The protein had an amino acid composition similar to the protein of cottonseed and the lipid was composed of cotton wax and cottonseed oil. It was suggested that the deposit material originates from immature cottonseed and it may be the same as material that causes saw tooth clogging, which can occur when early season machine-stripped cotton is ginned.

Secondary Metabolites of Gossypium: A Biogenetic Analysis

“…Only those which seem most unlikely to be cotton-derived natural products have been excluded. For example, the phthallates reported as "air space volatiles of the cotton plant" are likely artifacts derived from common plastics (9); some hydrocarbons found to be in cotton lint and waste probably came from a source obtained from petroleum (8); and aflatoxin is presumably a mold metabolite (36). A few other compounds have been excluded for similar reasons.…”
