| 中文摘要: |
| 采集不同产地和不同年份的盐肤木果籽，采用索氏抽提法提取盐肤木果籽油，对盐肤木果籽的主要组分和盐肤木果籽油的品质进行检测分析。结果表明：盐肤木果籽含粗脂肪9.41%~11.21%，粗蛋白质15.40%~19.38%，粗纤维31.50%~32.72%；盐肤木果籽油为暗黄色，酸值（KOH）5.4~7.3 mg/g，过氧化值0.9~1.2 mmol/kg；不同产地盐肤木果籽油的脂肪酸组成相差不大，主要脂肪酸为亚油酸（75.03%~75.37%）、油酸（12.58%~12.94%）、棕榈酸（7.93%~8.05%）、硬脂酸（2.05%~2.12%）、α-亚麻酸（1.24%~1.32%）；盐肤木果籽油中维生素E含量1 007.3~1 062.0 mg/kg，甾醇含量0.30%~0.42%，磷脂含量0.807%~0.873%。盐肤木果籽油经过精炼可以作为一种营养丰富的优质食用油。 |
| 英文摘要: |
| Sumac fruit seeds collected from different areas and years were extracted by Soxhlet extraction，then the main components in sumac fruit seed and qualities of sumac fruit seed oil were determined and analyzed. The results showed that the contents of crude oil，crude protein and crude fiber in sumac fruit seed were 9.41%-11.21%，15.40%-19.38% and 31.50%-32.72%，respectively. The color of sumac fruit seed oil was dark yellow. The acid value and peroxide value of sumac fruit seed oil were 5.4-7.3 mgKOH/g and 0.9-1.2 mmol/kg，respectively. The differences of fatty acid composition of sumac fruit seed oil from different areas were unconspicuous，and the main fatty acids were linoleic acid （75.03%-75.37%），oleic acid （12.58%-12.94%），palmitic acid （7.93%-8.05%），stearic acid （2.05%-2.12%） and α-linolenic acid （1.24%-1.32%）.The sumac fruit seed oil contained 1 007.3-1 062.0 mg/kg of vitamin E，0.30%-0.42% of sterol and 0.807%-0.873% of phospholipids. Sumac fruit seed oil could be used as a nutrient-rich and high quality edible oil after refining. |
