摘要/Abstract

摘要： 目的：综合研究云南丽江地区野生青刺果油的营养成分和功效。方法：采用国内外公认的标准方法进行常规理化、卫生指标及氨基酸、脂肪酸、无机元素等营养成分分析及评价。结果：青刺果油的特性常数为水分及挥发物0.03%、折光指数1.4716(n20)、相对密度0.9260(d2020)、碘值45.91(以I计)、皂化值0.02%、酸价0.17mg KOH/g，过氧化值1.20mmol/g，属于非干性油脂；营养指标为17种氨基酸总量为46.97%，其中含有7种人体必需氨基酸(异亮氨酸、亮氨酸、赖氨酸、蛋氨酸、苯丙氨酸、苏氨酸、缬氨酸)，为13.2%，占氨基酸总量的28.1%；富含VA(3.257mg/100g)、VD(1.745 mg/100g)、VE(8.736mg/100g)、VK(0.293mg/100g)、β-胡萝卜素(1.234mg/100g)等；13种矿物质微量元素含量最高的是K，为9.8mg/kg；脂肪酸13种，其中不饱和脂肪酸含量占78.35%，以油酸和亚油酸为主，含量均为38%，饱和脂肪酸、单不饱合脂肪酸和多不饱和脂肪酸组成比例接近于0.7:1:1，油脂营养结构合理，各项指标均符合部分国家食用大豆油标准(GB/T 1535-2003；Codex-Stan 210)。结论：丽江产野生青刺果油属于适合人类食用的天然功能性营养油。

Abstract: The aim of this study was to analyze the nutritional composition and evaluate the health efficacy of seed kernel essential oil from wild Prinsepia utilis Royle grown in Lijiang region, Yunnan province, China. The routine physicochemical properties, hygiene indexes, amino acid composition, fatty acid composition and mineral elements of the oil were assayed by the internationally recognized methods. The moisture and volatile matter content, refractive index, relative density, iodine value, saponification value, acid value and peroxide value of the oil, identified as a non-volatile oil, were 0.03%, 1.4716(n20), 0.9260(d2020), 45.91, 0.02%, 0.17 mg KOH/g and 1.20 mmol/g, respectively. The total content of 17 amino acids was 46.97%, including 7 essential amino acids (Ile, Leu, Lys, Met, Phe, Thr and Val) with a total content of 13.2%, accounting for 28.1% of total amino acids. The oil was rich in VA (3.257 mg/ 100 g), VD (1.745 mg/ 100 g), VE (8.736 mg/ 100 g) and β-carotene (1.234 mg/100 g). The content of K was the highest of 13 mineral elements tested, reaching 9.8 mg/kg. The content of unsaturated fatty acids was 78.35%, mainly oleic acid and linoleic acid with the same content of 38%. The proportion of saturated to monounsaturated to polysaturated fatty acids was 0.7:1:1, suggesting a well-balanced nutritional structure. Moreover, all indexes tested were in line with the national edible soybean oil standard GB/T 1535－2003 and the Codex-Stan 210. In light of these results, we conclude that seed kernel essential oil from wild Prinsepia utilis Royle grown in Lijiang region is a natural nutritional oil suitable for human consumption.
