Abstract
The rate of oil extraction from moist and dry rape seed was compared over an extraction time of 20 h and showed oil to be more readily extractable from oven‐dried seed. Three methods of determining the oil content by extraction of single samples were compared with a method in which a number of samples contained in single satchets were extracted in one large extractor. No significant differences were shown between any of the methods used, and it is proposed where sample numbers are large, and oil content is the only analysis required, that the multiple extraction method of oven‐dried seed is satisfactorily quick and accurate.
