Days after anthesis and postharvest behavior define maturity, harvesting time and nutraceutical content of camucamu fruit
Additional Document Info
2017 Elsevier B.V. Days after anthesis (DAA) and postharvest behavior were used as a novel integrative holistic approach to define the physiological and horticultural maturity of fruit and implement appropriate harvesting times for quality and nutraceutical content. Camu-camu fruit used as a model system was sampled between 74 and 116 DAA, studied on their chemical, enzymatic and sensory characteristics when still attached to the plant and during the postharvest life. At 7481 DAA fruit were physiologically immature, while 88116 DAA fruit were physiologically mature, with 116 DAA fruit showing overripe behavior. From a horticultural maturity view scenario there is a dual harvesting time for camucamu fruit where 88 DAA fruit shows a maximum peak for bioactive compound accumulation (phenolics, ascorbic acid, AOX) appropriate for the nutraceutical market, while 88102 DAA fruit reach higher sensory acceptance appropriate for the juice industry and fresh market. The horticultural maturity of camucamu fruit overlaps with its physiological maturity. This holistic approach can be extended to a diverse range of fruit crops.
