摘要：
21 apple juice samples from substandard fruits of various cultivars from 7 regions in China were collected to investigate the quality differences. 26 quality indicators of the juice samples were analyzed, including physicochemical and nutritional parameters and processing parameters. The core indicators were identified by Principal Component Analysis (PCA) and Cluster Analysis (CA) while the weights of core indicators were estimated by Analytic Hierarchy Process (AHP). Therefore, the quality evaluation model of the apple juices with different cultivars was established by Grey Interconnect Degree Analysis (GIDA). It has been suggested that total phenolic content, titratable acidity (TA), soluble solid content, turbidity, CIE L*, viscosity and browning index were the core indices which were used to evaluate of the juice quality. GIDA analysis showed that Shanxi Yuncheng "Granny Smith", Inner Mongolia "Crabapple", Yunnan Zhaotong "Fuji", Liaoning Huludao "Hanfu" and Shanxi Yuncheng "Qinguan" areproper for juice production among the 21 cultivars. The results in the present paper can be the guidance for selecting proper substandard apple for juice processing. © 2017, Editorial Office of Journal of CIFST. All right reserved.
