An Apparatus and Method for the Measurement of the Respiration of Cottonseed.

In the course of an investigation to determine the relationship of the respiration of cottonseed to the other processes which take place during storage, studies were made of the effect of moisture content, maturity, and inhibitors on respiration, rate of free fatty acid formation, and pigment changes in the oil. For these studies, a series of measurements w-;as required on about fifty different samples of cottonseed over a period of one year. In view of the large number of analyses needed, an apparatus designed to obtain accuracy and speed was built to follow the changes of the oxygen and carbon dioxide concentrations in the atmosphere surrounding the seeds. This apparatus and the methods used to make and record the measurements are described below. Methods
