| 摘 要： | 首先采用比色法测定了菠萝浓缩汁带皮榨汁生产过程中各工序下样品的褐变指数、总酚及原花青素的含量及变化情况,同时进一步用HPLC法确定了菠萝汁中单酚物质的种类和含量变化情况。研究表明,菠萝浓缩汁带皮加工过程中,总酚及原花青素含量与褐变指数是成正向相关的。

| Abstract: | The changes in total polyphenol, proanthocyanidin and browning index during pineapple juice concentrate processing were determined by spectrophotometer, and the change in individual phenolic compound in pineapple was done by high performance liquid chromatography (HPLC). The results showed that contents of polyphenols and proanthocyanidin were positively connected to browning index. |
