| 中文摘要: |
| 从全国7个省份采集9个油莎豆样品，对其杂质、粒度、容重、千粒重、种皮颜色、果仁颜色、粒型、粗脂肪、粗蛋白、粗纤维、水分、灰分及油莎豆油的酸价、过氧化值和脂肪酸组成进行检测，分析不同产地油莎豆的品质差异。结果表明：不同产地油莎豆的粒度表现出较大差异，其中大粒油莎豆为10~15 mm，小粒为6~10 mm，与粒度对应的千粒重指标也存在较大差异，为362~821 g，但无论颗粒大小，油莎豆的容重差异较小，为580~621 g/L；油莎豆的水分含量为5.43%~10.92%，灰分含量为1.63%~3.11%，粗脂肪含量为18.71%~26.71%，粗蛋白含量为4.66%~8.46%，粗纤维含量为6.64%~11.00%；油莎豆油的主要脂肪酸组成为油酸67.71%~74.60%、棕榈酸1242%~1478%、亚油酸8.79%~12.01%、硬脂酸2.37%~4.91%；油莎豆毛油酸价（KOH）为1.06~346 mg/g，过氧化值为0.02~0.92 g/100 g。 |

| Nine Cyperus esculentus samples were collected from seven provinces in China. The impurities, kernel measure, bulk density, thousand grain weight, seed coat color, nut color, kernel shape, crude fat content, crude fiber content, crude protein content, water content and ash content of Cyperus esculentus and acid value, peroxide value, fatty acid composition of Cyperus esculentus oil were determined to analyze the quality difference of Cyperus esculentus from different origins. The results showed that the kernel measure of Cyperus esculentus from different origins showed large differences, in which the large kernel measure was 10-15 mm and the small kernel measure was 6-10 mm. There was also large differences in thousand grain weight corresponding to the kernel measure, which was 362-821 g. Regardless of the size of the kernel measure, the difference in bulk density of Cyperus esculentus was small,which was 580-621 g/L. The contents of water, ash, crude fat, crude protein and crude fiber in Cyperus esculentus were 543%-10.92%, 1.63%-3.11%,18.71%-26.71%,4.66%-8.46% and 664%-1100%, respectively. The main fatty acid of Cyperus esculentus oil was oleic acid (67.71%-7460%), palmitic acid (12.42%-14.78%), linoleic acid (8.79%-12.01%), stearic acid (237%-4.91%), and the acid value and peroxide value of crude oil were 1.06-3.46 mgKOH/g and 0.02-0.92 g/100 g respectively. |
