Deskripsi
<strong>Purpose:</strong> Strawberry (<em>Fragaria</em> × <em>ananassa</em>) is highly perishable fruit with a limited postharvest life at room temperature and is vulnerable to postharvest decay due to its high respiration rate, environmental stresses and pathogenic attacks. <strong>Research method:</strong> To increase the postharvest life of strawberries, a combination of packaging material (polyethylene and perforated polyethylene) along with control and storage conditions {zero energy cool chamber (ZECC) and ambient conditions in laboratory} were tested. <strong>Main findings:</strong> Mass loss (1.59%) and internal temperature (22.24°C) were significantly reduced while shelf-life (more than 3 days) was enhanced in ZECC as compared to ambient conditions in laboratory with 6.46% mass loss, 23.04°C internal temperature and less than 3 days shelf-life. Packaging material significantly influenced mass loss (%) and electrical conductivity (S/m) of strawberry juice irrespective of its interaction with storage conditions and storage durations. Maximum mass loss (9.11%) and EC (3.74 S/m) were recorded in control samples while, minimum mass loss (1.24%) and EC (3.52 S/m) was recorded in polyethylene enclosed fruit. Irrespective of storage conditions and packaging material pH, TSS, titratable acidity (%) and ascorbic acid (mg100 ml<sup>-1</sup>) decreased while electrical conductivity (S/m) increased during storage. <strong>Limitations:</strong> In future study storage duration should be extended by adding more removals to get clear difference in fruit quality and shelf-life under various treatments.<strong> Originality/Value:</strong> In conclusion ZECC can be used for short term storage of strawberry.
