摘要
优化了应用离子色谱检测巴厘菠萝果实糖分组成与含量的方法,经优化的测定分析条件为:CarboPac PA1(2×250 mm)分离柱,淋洗液40 mmol/L NaOH溶液,流速0.25 mL.min-1,柱温30℃;用该方法对经果蜡处理的巴厘菠萝果实贮藏期间的糖分组成和含量进行了有效分离与测定。结果表明,果蜡处理组与对照组菠萝果实的糖分都是以蔗糖为主,其次为葡萄糖和果糖;贮藏期间,处理与对照组果实主要的3种糖含量均呈不断下降趋势,但果蜡处理组果实的葡萄糖和蔗糖含量总体上明显高于对照,表明果蜡处理对保持菠萝采后品质有一定作用。
An ion chromatography was applied to determine measurements were performed on a Dionex CarboPac PAl sugar in pineapple fruit during storage. The separation and （2×250 ram） column at 30 ℃ with 40 mmol/L NaOH as eluent at a flow rate of 0.25 mL· min^-1. The results showed that the most sugar component was sucrose, and then glucose and fructose in pineapple fruit stored at normal temperature. The sugar components in both controled and compared group decreased constantly during storage while the waxed fruit had significantly higher levels of glucose and sucrose, suggesting that waxing had an effect on maintaining the fruit quality of harvested pineapples.
