Temperature of 4?C with appropriate MP packaging allows a 5 day extension of the shelf life of strawberry

Strawberry has antioxidant and nutraceutical properties useful for human health and is appreciated by the consumer, so much so that in Italy,since 2000, there has been an increase in the purchase of 31%. As part of the many issues that distinguish this fruit, the post-harvest management turns out to be one of the most important both in terms of shelf life and quality/nutritional product properties. Qualitative traits obviously change during the post-harvest together with organoleptic and sensorial ones. In this regard, several parameters were evaluated during the post -harvest and in order to understand how they are influenced on the basis of innovative packaging and different storage temperatures. Strawberry cv Elsanta, was packed in polypropylene bags (PP) with different numbers of microperforations (MP) (open, 0 MP and 6 MP) and stored at three storage temperatures (4?C, 10?C and 18?C).Dry matter, pH, titratable acidity, electrical conductivity, sugar, color, vitamin C, antioxidant capacity, total phenols,flavonoids and phenolic acids were evaluated. O2 and CO2 exchange was monitored too.The conservation at a temperature of 4?C gave the best result as regards the maintenance of the quality characters and especially the respiration rate that has not led to a rapid decay. Temperature, if combined with MP packaging, stabilized gas exchange increasing shelf-life. The packaging with 6 MP, coupled to an appropriate temperature of 4?C, allowed the extension of the shelf-life of 5 days reducing the dehydration of the product of 50% and retaining the qualitative properties.SourcesEFFECT OF POSTHARVEST THERMAL STRESS AND TEMPERATURE ON QUALITATIVE TRAITS IN STRAWBERRYNicoletto, C1, Santagata, S1, Zanin, G1, Sambo, P1carlo.nicoletto@unipd.it1University of Padova, Padova, Italy IHC 2014, International Horticulture Congress, 17-22 August 2014, Brisbane, http://www.ihc2014.org/Picture by mlp.wikia.com Key wordsFresa?? ?frutilla?? ?strawberry strawberries?? ?aarbei?? ??????????? ????? ??? ?fraise?? ?????????? ????????????? ?aardbei?? ?fragola?? ?truskawka?? ?morango?? ??????????? ??ilek?? ???????????? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ?Poscosecha?? ?postcosecha?? ?postharvest?? ?na-oes?? ??? ??? ???????? ????? ??? ?post-r?colte?? ????? ?? ??????????? ??? ?na-oogst?? ?post-raccolta?? ?Obr?bka po?? ?p?s-colheita?? ????????????????? ?hasat sonras??? ??? ?Ernte?? ????????????????? ????? ????????????? ?postcollita?? ?poskliz?ov頠 ????? ??? ??? ??? ?nakon branja?? ?pozberov頠 ??? ?obdelovanje zemlje po?? ?post-colleita?? ?????? ??????? ?pascapanen?? ??il?onn postharvest?? ??????? ?p?c ra?as?? ?derliaus apdirbimas po?? ?lepas tuai?? ??? ?? ???????? ?post-recoltare?? ??????? ??????? ???????????????????? ?????????????? ?????????????????? ?sau thu ho?ch?? ?????????????????? ?zangemva kwenkathi yokuvuna?? ???? ?
