and summary The effects of moisture content, age, growing location, and genotype of flaxseed on the efficiency of pressure extraction of oil, when extracted in a Carver press cylinder, were examined. Decreasing the seed moisture content from 7.8% to 2.3% increased the proportion of oil extracted from 31.4% to 49.6%, respectively. Oil was more difficult to extract as the age of the seed increased. The proportion of the total oil extracted varied from 25.0% to 41.4% depending upon the location where the seed was grown. The effect of genotype was less pronounced, ranging from a mean of 46.9% in Redwing to 54.2% in Redwood 65 for samples analyzed at normal storage moisture. Samples with high oil contents usually yielded the highest proportion of total oil recovered (r=0.893 ** , 9 df).
