• 中文摘要： 1. 赳省內各大植物油廠採取植物油渣供試，以探討提煉其中脂肪之方法，並將其成分分析之， 以與牛油比較。2. 提煉油渣中脂肪之方法，經試驗結果發現以蒸氣加熱分離方汰，在成分及操作上最佳。3. 以蒸氣加熱分離法所提煉之脂肪、其成分為總脂質（亦即粗脂肪之意）89.6 5.2%。其中 總脂質之含量卑牛油中者相近，但游離脂肪酸則較多，水分、夾雜物及不皂化物之含量各為 1.97 0.36%，1.51 0.37%，及5.44 2.99%。水分與夾雜物之含量與牛油中之含量幾無 差異，但不皂化物量則比牛油中所含者多約10倍。4. 脂肪酸組成之分析結果顯示與黃豆油之脂肪酸組成幾無差異。不飽和脂肪酸約佔75~82%， 其中以亞油酸（Linoleic acid）、油酸（oleic acid）及亞麻油酸（Linolenic acid）之比率 為最多。飽和脂肪酸中以棕櫚酸（Palmitic acid）之比率為最多。
• 英文摘要： 1. In this research, the methods form pre- paring oils from soybean foots were carried out. Some charateristics were compared with those of tallow.2. Steam distillatioin was found to be the best method for extracting the oils from soybean foot.3. The moisture content, non-saponiflable matter and insoluble matter and insoluble matter of the oil prepared from soybean soapstocks by steam distillation ware fund to be 1.97 0.36%, 1.31 0·37% and 5.44 2.99%, respectively. The moisture content and insoluble matter were, quantitatively, quite similar to those of tallow, while the content of non- saponifiable matter was about 10 times higher than that of tallow. 4. The fatty acid comppsition of the oil prepared by steam distillation was quite similar to that of soybean oil. The content of unsaturated fatty acids was about 75 to 82%. The major unsatnrated fatty acids were linoleic, oleic and linolenic acids, and the major saturated fatty acid was palmitic acid.
