Comparison of quality, major bioactive compound content and antioxidant capacity between Southern high-bush blueberries (Vaccinium corymbosum) and rabbit-eye blueberries (Vaccinium ashei)
Abstract:Three southern high-bush blueberry (Vaccinium corymbosum) and two rabbit-eye blueberr (V. ashei) cuhivars were involved in the experiment. Fruit quality , sugar and acid composition , antioxidant properties and activity were analyzed. Results showed that of the 5 cultivars, Misty produced the biggest fruit, Gardenblue had the highest soluble solids content, while Powderblue and Misty had the lower titratable acid. Glucose and fructose were the predominant sugars in the pulp; the main acid were citric acid, malic acid, quinic acid and tartaric acid, and different cultivars showed remarkable difference in organic acid compositions. Anthocyanins, phenolics and flavonoids were the main antioxidant compounds and Powderblue had the highest total anthocyanin content, while Gardenblue had the highest phenolic and flavonoid content. Gardenblue and Powderblue showed higher antioxidant activity than the other cul-tivars, as measured by assays of 1,1-diphenyl-2-picrylhydraz scavenging(DPPH) , 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) scavenging(TEAC) and Ferric reducing antioxidant power(FRAP).
