- Abstract
In order to understand the mineral content of kiwifruit produced in Meixian county, Shaanxi province and evaluate IS related nutritional value. The contents of 9 minerals in four varieties of kiwifruit, namely Xuxiang, Cuixiang, Hongxin and Huangxin, produced mainly in Shaanxi Meixaan, 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 mineral and energy. The four varieties of kiwifruit in Shaanxi Meixaan were mainly composed of P,K,Ca, and Mg, accounting for approximately 99.8 V 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 Xuxaing was 16.78 (INQ total). The correlation analysis showed that there was varying degrees of correlation between various elements, and the highest correction 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.
