摘要
为探究陕西眉县所产猕猴桃中矿物质含量及评价其相关营养价值。利用电感耦合等离子体发射光谱(ICP-OES)法对陕西眉县主产的徐香、翠香、红心、黄心四个品种猕猴桃中9种矿物质含量进行测定,并采用营养质量指数法(Index of nutritional quality,INQ)对矿物质元素进行营养评价,同时应用SPSS软件对9种矿物质和能量进行相关性分析。陕西眉县四个品种猕猴桃矿物质均以钾、磷、钙、镁四种元素为主,约占总矿物质的99.8%,四个品种中INQ均大于1的矿物质有钙、钾、镁、铜,其中钾的INQ最高在3.89~5.19。矿物总量最高的品种为翠香328 mg/100g,但营养质量指数最高的为徐香16.78(INQ_(总))。通过相关性分析表明各元素间存在着不同程度的相关性,其中钾与能量的相关系数最高为0.982。猕猴桃是一种高钾低钠的优质食品,不同品种猕猴桃矿物质元素的营养价值差异明显,矿物质营养密度最高的为翠香,其次为红心、黄心、徐香,但从营养价值指数方面来看,徐香最高,翠香次之,红心和黄心猕猴桃矿物营养水平稍逊。
In order to understand the mineral content of kiwifruit produced in Meixian county,Shaanxi province and evaluate its related nutritional value.The contents of 9 minerals in four varieties of kiwifruit,namely Xuxiang,Cuixiang,Hongxin and Huangxin,produced mainly in Shaanxi Meixian,were determined by inductively coupled plasma atomic emission spectrometry.The nutritional evaluation of mineral elements was carried out by the index of nutritional quality(INQ) method.Simultaneously,SPSS software was used to analyze the correlation between 9 minerals and energy.The four varieties of kiwifruit in Shaanxi Meixian were mainly composed of P,K,Ca,and Mg,accounting for approximately 99.8% of the total minerals.The INQ greater than 1 in all four varieties included Ca,K,Mg,and Cu,and the INQ of K was the highest,ranging from 3.89 to 5.19.The total mineral content of Cuixiang was the highest,328 mg/100g,but the highest nutritional quality index of Xuxiang was 16.78(INQ total).The correlation analysis showed that there was varying degrees of correlation between various elements,and the highest correlation coefficient between K and energy was 0.982.Kiwifruit was a high-quality food with high K and low Na.The nutritional value of mineral elements in different varieties of kiwifruit was significantly different.The highest mineral nutrient density was Cuixiang,followed by Hongxin,Huangxin,and Xuxiang.According to the nutritional value index of 9 mineral elements,Xuxiang was the highest,Cuixiang followed,and the mineral nutrition level of Hongxin and Huangxin kiwifruit were slightly lower.
