摘要

在六个月的时间里，对清洗过的杂草种子筛选和筛选油(商业溶剂提取)的月度样本进行了检查，结果表明，筛选物的成分变化很大，但油的成分却非常稳定。杂草种子的组成为:野生芥菜，以芸苔类植物为主(53-79%，68%)，混合杂草种子(13-35%，23%)，作物种子(4-10%，6.6%)，破碎和未识别种子(1-6%，3%)。皂化数，182;游离脂肪酸(如油酸)，2%;相对透光率(含矿物油)，440 μ m时5%，540 μ m时18%，660 μ m时26%。油的外观和对加工的反应与油菜和芥菜籽油相似。小规模的口味小组测试表明，加工过的筛选油通常不如玉米或棉籽色拉油美味，但筛选起酥油通常与对照(商业蔬菜起酥油)一样可接受。

CANADIAN ERUCIC ACID OILS: V. PHYSICAL, CHEMICAL, AND EDIBLE PROPERTIES OF OIL FROM WEED SEED SCREENINGS

Monthly samples of cleaned weed seed screenings and of screenings oil (commercially solvent extracted) examined over a six-month period indicated that the composition of the screenings varied widely but that of the oil was remarkably constant. The composition of the weed seed was: wild mustard, mostly Brassica arvensts (53–79% av. 68%) mixed weed seeds (13–35%, av. 23%), crop seeds (4–10%, av. 6.6%), and broken and unidentified seeds (1–6% av 3%) The average characteristics of the oil were: iodine value, 124; saponification number, 182; free tatty acid (as oleic), 2%; relative light transmission (cf. mineral oil), 5% at 440 mμ, 18% at 540 mμ, 26% at 660 mμ. Appearance of the oil and response to processing were similar to those of rape and mustard seed oils. Small scale taste panel tests indicated that processed screenings oil was generally not as palatable as corn or cottonseed salad oils, but that screenings shortening was generally as acceptable as the control (commercial vegetable shortenings) the scre...
