Comparative analysis of physicochemical component content in blueberry fruit and their function evaluation.

The physicochemical component contents in the fruits of 8 blueberry varieties were detected,the results indicated that there were obvious differences in the physicochemical component contents among different varieties.The ratio of sugar to acid was between 10.12% and 18.61%,and the content of superoxide dismutase(SOD) was between 2.8×104 and 3.7×104 U/kg.The content of K,Mg,Ca,Fe and Zn element was high,and the content of vitamin B1,B2,B6 and Ve was abundant.The total content of anthocyanin in blueberry varieties Brightwell,Gardenblue and Powderblue was 187.84,350.76 and 269.67 mg/100g,respectively.Furthermore,the paper evaluated the function of every physicochemical component of blueberry.
