摘　　要：采用单因素和正交实验,进行了植酸和超高压对啤酒色度的影响研究。结果表明,植酸在高压条件下保持啤酒色度稳定性的最佳工艺条件为:作用压力400MPa,加压时间5min,植酸浓度为0.07‰。在此工艺条件下,色度为4.229,比未经处理的对照样品下降了6.44%;植酸、超高压及其协同作用均能保持啤酒色度稳定性。The effects of phytic acid and UHP on beer colority stability were studied by single factor test and orthogonal experiments. The optimum techical conditions for phytic acid under UHP to maintain beer colority stability were summed up as follows： action pressure as 400 MPa, UHP treatment for 5 min, and phytic acid concentration was 0.7‰. Under such conditions, beer colority was 4.229, 6.44 % decrease compared with untreated beer samples. Accordingly, phytic acid, UHP and UHP-assisted phytic acid treatment could maintain beer colority stability effectively.
