Nutritional components and active substance in comparative analysis of different parts of blueberry

To study on the distribution of nutrition and active substance in different parts of the blueberries.Total acid,total sugar,flavonoid,phenol,anthocyanins,protein,fat,vitamin C and ash content were studied in different parts( pulps,peels and whole fruit) of blueberries( Yuanlan).The results showed that the content of total acid,protein,anthocyanins,flavonoid,phenol in the peel of blueberries were( 1.927 ± 0.004) mg / g,( 0.88 ± 0.04) g /100 g,( 1312.4 ± 175.9) mg /100 g,( 2.85 ± 0.40) mg /g,( 3.89 ± 0.52) mg /g,respectively,which were significantly higher than that in pulps and whole fruit( p < 0.05).Total sugar was mainly distributed in pulps( p < 0.05),but total acid,anthocyanins,flavonoid and phenol in the pulp was the least.Peels as processing waste discarded in the machining process of blueberry juice and wine,it always causing the huge waste of resources.Therefore,nutrition in the peels of blueberries is proved to have applicable values and potential on deep processing.
