Effects of active and passive modified atmosphere packaging on biochemical properties of cut Dendrobium orchid flowers

Abstract

Optimal storage conditions are essential to preserving the quality of postharvest produce and cut flowers during transportation, especially to overseas destinations. As a result, this research investigated the effects of active and passive modified atmosphere packaging (MAP) on the biochemical properties of cut Dendrobium Sonia orchid flowers. In active MAP, the orchid flowers were wrapped in MAP plastic film filled with 5 % carbon dioxide (CO 2 ) and 2 % oxygen (O 2 ). Meanwhile, in passive MAP the flowers were stored inside MAP plastic film without filling with 5 % CO 2 and 2 % O 2 . The experimental MAP plastic films were polyethylene, low density polyethylene, high density polyethylene, polypropylene, and polyvinyl chloride films. The biochemical parameters included storage life, respiration rate, ethylene production, internal O 2 and CO 2 , anthocyanin content, protein degradation, and electrolyte leakage. The results showed that the average storage life of orchid flowers under passive MAP condition was 9–15 days, depending on the plastic film types. The longest storage life of 15.66 days was achieved with polypropylene film. The storage life of orchid flowers in active MAP was 9.33 days on average. Without MAP (control), the storage life was 7 days under normal atmosphere condition (0.03 % CO 2 and 21 % O 2 ). The experiments also demonstrated that MAP efficiently reduced respiration rate, ethylene production, anthocyanin degradation, protein degradation, and electrolyte leakage. Unlike existing research on MAP which focused primarily on extending the shelf life of fresh produce or cut flowers, this study comparatively investigated the biochemical properties of cut orchid flowers stored in MAP environment, in addition to the storage life.

An analysis of conventional and modern packaging approaches for cut flowers: a review article

“…These alterations encompass petal discoloration, petal detachment, tissue browning, and wilting. MAP manipulates the CO 2 and O 2 levels within the package to inhibit these changes ( Poonsri, 2021 ). It is important to note that flower species differ considerably in their responses to altered circumstances during storage ( Zeltzer et al., 2001 ).…”

A new strategy to design novel modified atmosphere packaging formulation maintains the qualities of postharvest strawberries (Fragaria ananassa) during low‐temperature storage

“…Therefore, they have been commonly considered products targeted for modified atmosphere packaging (MAP) applications, notably due to their short shelf life, susceptibility to mechanical damage, post‐harvest metabolic alterations, moisture loss, and spoilage (Cristiana et al, 2014; Giuggioli et al, 2017; Lee, 2021; Poonsri, 2021; Sousa‐Gallagher et al, 2016). These changes have prompted producers and traders to develop new strategies to reduce losses during the transport and storage of vegetables, fruits, and flowers and to improve their shelf life, with the expectation that innovations in packaging technology and conditions will play a key role in maintaining product quality (Poonsri, 2021). Even commercial open‐fridge showcases hardly ever reach air temperatures below 5°C (Gimeno et al, 2022).…”

“…Even commercial open‐fridge showcases hardly ever reach air temperatures below 5°C (Gimeno et al, 2022). However, MAP is the most cost‐effective, versatile, widely used preservation approach available today, with a retail application focus on improving the safety and hygiene of fresh foods, extended shelf life, and storage lifespan of fresh agricultural products and cut flowers (Lee, 2021; Poonsri, 2021). Thus, in this study, we propose developing a new atmospheric packaging system to balance the gas content in the package (low O 2 and CO 2 production).…”
