Abstract:
The storage characteristics of different varieties of blueberry fruits were studied in Jizhou District of Tianjin and stored at -1 ℃ in 70 days,and changes of 8 indicators in fruit were studied.The results showed that when stored at the 14th day in fruit hardness，the 35th day in vitamin C and anthocyanin content and the 42th day in good fruit ratio and soluble sugar content,the indicators declined significantly.The fruit hardness declined first in all index.The contents of soluble solids，total phenols and flavonoids first increased and then decreased.When the fruits were stored to the 70th day，good fruit rate of each variety had gradually decreased，which was above 80%；the hardness,soluble solid and the soluble sugar content decreased from 20% to 49%，7% to 36%，and 18% to 41%.The vitamin C，total phenol，flavonoids and anthocyanins contents reduced from 28% to 53%，6% to 40%，29% to 74%，and 20% to 54%.All indicators of ‘Brigitta’ were the highest except for flavonoids.The flavonoid was the highest in fruits of ‘Bluegold’.The comprehensive analysis of the membership function showed that the storability from high to low was：‘Brigitta’>‘Bluegold’>‘Legacy’=‘Northland’=‘Bluecrop’=‘Reka’>‘O′Neal’>‘Berkeley’.
