COMPARISON OF RESPIRATION, FREE FATTY ACID FORMATION, AND CHANGES IN THE SPECTRUM OF THE SEED OIL DURING THE STORAGE OF COTTONSEED

Abstract

Lipolysis measurements were made on the same samples of seeds which had been used for respiration measurements. The lipolysis rate constants were detd. for all the seeds and it was found that these constants increased in a regular manner with increase of moisture content of the seeds. In addition to the lipolysis measurements, the spectra of the solvent-extracted oils were detd. and were shown to vary during storage. The variety of seeds which exhibited the greatest vigor with respect to respiration also had the greatest vigor with respect to lipolysis. Immature seeds had a higher respiration intensity and a different lipolysis pattern from that of normal seeds.
