Antioxidant activity of anthocyanins from quixabeira (Sideroxylon obtusifolium) fruits
The fruits of Sideroxylon obtusifolium T.D. Penn. are small berries which have dark purple skin color at maturity due the anthocyanins presence. Therefore, the aim of this research was to evaluate the antioxidant activity of anthocyanins from mature fruits which were obtained at a semi-arid region of Paraiba/BR. In addition, the total anthocyanins content was measured by the pH differential met...
متن کاملThe Stability and Antioxidant Activity of Anthocyanins from Blueberry
Anthocyanins from highbush blueberry (Vaccinium corymbosum L.) have tremendous potential as natural colorants and functional food with pharmaceutical purposes in food applications. To exploit the potential for food applications, the stability and antioxidant activity of anthocyanins present in blueberries have been studied. The results indicate that anthocyanins from blueberry were stable again...
متن کاملEffect of high-oxygen atmospheres on blueberry phenolics, anthocyanins, and antioxidant capacity.
The influence of high oxygen concentrations on total phenolic, total anthocyanin, individual phenolic compounds, and antioxidant capacity (measured as oxygen radical absorbance capacity, ORAC) in highbush blueberry fruit (Vaccinium corymbosum L. cv. Duke) was investigated. Freshly harvested blueberries were placed in jars ventilated continuously with air or with 40, 60, 80, or 100% O(2) at 5 de...
متن کاملChanges in strawberry phenolics, anthocyanins, and antioxidant capacity in response to high oxygen treatments
Changes in fruit quality, decay, phenolic and anthocyanin content, and antioxidant capacity of strawberries (Fragaria ananassa Duch. cv. Allstar) stored under air and high oxygen atmospheres at 5 1C were investigated. Freshly harvested strawberries were placed in jars and ventilated continuously with air or with 40, 60, 80, or 100 kPa O2 at 5 1C for up to 14 days. Samples were taken initially, ...
متن کاملAnthocyanins, phenolics, and antioxidant capacity in diverse small fruits: vaccinium, rubus, and ribes.
Fruits from 107 genotypes of Vaccinium L., Rubus L., and Ribes L., were analyzed for total anthocyanins (ACY), total phenolics (TPH), and antioxidant capacities as determined by oxygen radical absorbing capacity (ORAC) and ferric reducing antioxidant power (FRAP). Fruit size was highly correlated (r = 0.84) with ACY within Vaccinium corymbosum L., but was not correlated to ACY across eight othe...
