摘要:

以糖渍加应子为研究对象,考察传统热风干燥、热泵干燥和太阳能干燥3种干燥方式对糖渍加应子干燥效率和品质的影响。结果表明:通过热泵干燥、热风干燥和太阳能干燥3种干燥方式使糖渍加应子降至干基湿含量为(30±1)%所需时间分别为6、7、13.5h。其中,热泵干燥的干燥效率最高。3种干燥方式对糖渍加应子色泽的影响差异不显著。热泵干燥与热风干燥所得糖渍加应子在硬度和风味品质上较为接近。太阳能干燥所得糖渍加应子的硬度最小,挥发性成分的种类和挥发性风味成分的绝对含量的增加量最大,品质最佳。

Abstract:

The effects of three different drying methods, conventional hot air drying (HAD), heat pump drying (HPD) and
solar drying (SD) on the drying efficiency and quality of candied prunes were investigated. Results showed that the drying
time for reaching the dry-base moisture content of (30 ± 1)% under HPD, HAD and SD conditions were 6, 7 h and 13.5 h,
respectively. HPD was the most efficient drying method. No obvious difference in the effects of three different methods on
the color of candied prunes was observed. HPD-treated and HAD-treated candied prunes had similar qualities in hardness
and flavor, while the hardness of SD-treated candied prunes was the smallest and the maximum increase was observed in the
number and absolute contents of volatile flavor compounds detected in SD-treated candied prunes, indicating that the quality
of SD-treated candied prunes was the best.

Key words: candied prune, hot air drying, heat pump drying, solar drying, quality
