摘要
以浓缩苹果汁为试材,设计色值和透光率2项实验指标,在2种流速下,对3种树脂吸附提高果汁色值进行调控研究,以期提高果汁色值,控制褐变。得到实验结果:在4、6 BV/h条件下,3种树脂吸附果汁能力的变化趋势一致,均为LKS03>LSA-900E>LKS06;处理组果汁的色值稳定性为LSA-900E≥LKS06≥LKS03;再者,苹果汁以6 BV/h的流速通过树脂柱更适于维持其色值稳定性。
Concentrated apple juice as test material, and design color values and light transmittance of two experimental index, Under two kinds of flow velocity, the condition of three kinds of resin adsorption increase juice color value control study, in order to improve the juice color values, control browning. The results show that under 4 BV/h and 6 BV/h, the three kinds of resin adsorption juice＇s ability to change tendency is consistent, both are LKS03LSA-900ELKS06, the fruit juice of treatment group color value stability LSA-900E≥LKS06≥LKS03, moreover, fruit juice with 6 BV/h velocity through the resin column is more suitable for maintaining the stability of color value.
