Fresh strawberries (cv Camarosa) were collected from a local agro-industry at commercial maturity, washed, dried, and stored at 4\u00a0\u00b0C with 4% and 8% AITC, in free form and encapsulated in zein fibers. The strawberries were analyzed for weight loss, firmness, titratable acidity, soluble solids concentration, and pH from day 0 (fresh strawberries) to 20, every five days. After 15 days of storage, the strawberries were also analyzed for free phenolic content,\u00a0antioxidant capacity\u00a0using ABTS and DPPH methods, and total anthocyanin content. AITC successfully reduced weight loss of strawberries for an additional five days. The encapsulation of AITC using zein was efficient when lower concentrations (4%) are applied. The increase of AITC on zein fibers saturated the medium and reduced fruit quality. All AITC treatments significantly reduced the firmness and reddish color of the stored strawberries, the AITC addition suppressed the total phenolic and anthocyanin contents. These findings suggest that low concentrations of AITC encapsulated in zein fiber provide a promising method to maintain strawberry quality.<\/h3>\n<p><a href=\"https:\/\/doi.org\/10.1016\/j.lwt.2021.111087\">https:\/\/doi.org\/10.1016\/j.lwt.2021.111087<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Rosana Colussi, Wyller Max Ferreira da Silva, Barbara Biduski, Shanise Lisie Mello El Halal, Elessandra da Rosa Zavareze, Alvaro Renato Guerra Dias Abstract The aim of this study was to encapsulate allyl isothiocyanate (AITC) in zein ultrafine fibers and evaluate its effects as active packaging on postharvest quality of strawberry.
