摘要:

为掌握夏季设施栽培云南楤木嫩芽营养成分变化规律,对其同一年份不同月份和不同年份同一时期的矿质元素、氨基酸和糖酸等含量进行试验研究。研究结果表明,设施内采摘的云南楤木嫩芽中含有丰富的营养物质,氨基酸含量6月最高(17.46%),糖、酸和维生素C含量在7月最高,总糖、总酸为1.59%,维生素C为9.00 mg/100 g,矿质元素含量9月最高(8024.32 mg/kg)。通过对4个不同月份营养成分的比较分析, 9月云南楤木嫩芽中的营养成分含量较高、营养均衡。通过对不同年份同一时期的营养成分分析,2014年9月的营养价值相对较高,营养相对均衡,氨基酸的SRC值为95.36,糖、酸含量为1.02%,维生素C为4.7 mg/100 g。而矿质元素含量在2018年9月最高,为7670.32 mg/kg。

Abstract:

To grasp the variation of nutritional components of shoots of Aralia thomsonii under facility cultivation in summer, this paper studies the contents of mineral elements, amino acids and sugar acids in different months of the same year and the same period in different years. The results showed that the shoots of A. thomsonii harvested in facilities contained abundant nutrients. Amino acid content was the highest in June (17.46%). The contents of sugar, acid and vitamin C were the highest in July, with 1.59% of sugar and acid and 9.00 mg/100 g of vitamin C. The content of mineral elements was the highest in September, which was 8024.32 mg/kg. Through comparing and analyzing nutritional components in four different months, it was found that in September, the content of nutrients in the shoots of A. thomsonii was relatively high and the nutrients were balanced. As to the nutritional components in the same period in different years, in September 2014, the nutritional value was relatively high and the nutrition was relatively balanced with SRC value of amino acids of 95.36, the content of sugar and acid of 1.02%, and vitamin C of 4.7 mg/100 g, while the content of mineral elements was the highest in September 2018 (7670.32 mg/kg).

Key words: Aralia thomsonii, shoots, nutritional components, different months, different years
