Abstract The phenolic compounds and aroma active compounds in feijoa (Acca sellowiana (O.Berg) Burret) juice from four New Zealand grown cultivars (Apollo, Unique, Opal Star, and Wiki Tu) were investigated. A high total phenolic content (maximum 1.89 mg GAE/mL juice) and significant antioxidant activities (maximum 14.66 mM Trolox/mL juice) were determined in feijoa juices. A total of 7 phenolic compounds from the screening of 29 standards were identified and quantified by LC-MS, with procyanidin...

For the first time, thinned young kiwifruits (TYK) have been investigated as a source of deserted agriculture resource and evaluated for their phenolic characteristics along with antioxidant capacity. Two batches of TYK in different maturity stages (TYK1 and TYK2) and mature kiwifruits (MK) were sourced from three New Zealand cultivars. Comparing with MK, the TYK, especially TYK1, exhibited significantly higher contents of total phenolics (7.92 fold), total flavonoids (17.56 fold) and total flav...

This study investigated the effects of vinification techniques and cultivars (Stevens, Pilgrim and Bergman) on cranberry wine quality. Three winemaking technologies were conducted to prepare cranberry musts before fermentation, including traditional red and white vinifications (Red and White), and thermovinification (Thermo). In wine products, proanthocyanins (PACs) and anthocyanins (ANCs) are dominant in phenolics, while esters and alcohols are prevalent in volatiles, with phenylethyl alcohol, ...
