Whether vitamin C from wholefoods has equivalent bioavailability to a purified supplement remains unclear. We have previously showed that kiwifruit provided significantly higher serum and tissue ascorbate levels than synthetic vitamin C in a genetically vitamin C-deficient mouse model, suggesting a synergistic activity of the whole fruit. To determine if these results are translatable to humans...

Kiwifruit are a rich source of vitamin C and also contain numerous phytochemicals, such as flavonoids, which may influence the bioavailability of kiwifruit-derived vitamin C. The aim of this study was to compare the relative bioavailability of synthetic versus kiwifruit-derived vitamin C using a randomised cross-over pharmacokinetic study design. Nine non-smoking males (aged 18-35 years) receiv...

Kiwi fruit (Actinidia chinensis Planch.) seeds, present as a by-product in the food and pharmaceutical industries, remain underutilized. In this study the extraction conditions for the maximum recovery of total phenolic content (TPC) with high DPPH scavenging capacities (DPPHsc) were analyzed for kiwi fruit seed polyphenols (KSP) by response surface methodology. The optimal conditions for the h...

Abstract Kiwifruit is a new emerging crop for the southeastern United States that requires cross-pollination to set fruit. However, pollination requirements varieties grown in are unknown. Through insect surveys and bagging experiment, we assessed of two female kiwifruit cultivars (Actinidia chinensis var. ‘AU Golden Sunshine’ A. Gulf Coast Gold’). For each, fruit quantity (fruit set) quality (...

Managers of insect-pollinated orchards face many decisions that can significantly influence crop yields, including managing pollination through use beehives or the layout cultivars in orchard. Understanding relative importance and interactions between these multiple empirical field trials is rarely possible, so modeling approaches provide valuable insights generate new hypotheses. Based on kiwi...

Visible/near infrared spectroscopy (Vis-NIRS) was used to monitor the yellow-fleshed kiwifruit (Actinidia chinensis Planch ‘Jintao’) ripening on two selected orchards along 13 weeks, from pre-harvest late harvest. Calibration models for several Internal Quality Attibutes (IQA) were built spectral data of 375 individual kiwifruit. The analyzed IQA L*, a* and b* CIELAB color space, hue angle, chr...
