Prolong post-cutting life of fresh-cut jackfruit

Abstract

Jackfruit (Artocarpus heterophyllus Lam.) is a favorable fruit with delicious taste but the storage time of its fresh-cut product is just 1- 2 days. The aim of this study is prolonging life-time of fresh-cut jackfruit. Two main experiments were carried out. First, jackfruit packaged in PS tray and PVC film was treated with ozone or hot air in different conditions. Second, the samples were packaged in PA film with some modifiedf atmosphere such as 100%N₂, 100%O₂, and vacuum atmosphere. Samples temperature was held at 5⁰C. Total plate count, moisture content and some of physicochemical index were tested every day.

The best results were shown in both samples that were treated with ozone gas in 1 minute and that were stored in atmosphere of 100% N₂. There were no remarkable changes in quality parameters of these samples; microbial criteria were also ensured until 7^th day.
