Design of a modified atmosphere storage system for shelf life enhancement of mango ( Mangifera indica , cv. Amrapali )

Abstract

Modified atmosphere storage (MAS) system was developed under passive as well as active conditions for bulk handling and storage of mango. The developed mathematical model used in the design process was validated and found to be appropriate, as indicated by moduli (E < 10%). The use of O2 absorber in the active MAS system has extended the shelf life of mango by 3.5 times as compared to control along with maintaining good quality attributes at the end of the storage period at ambient temperature (27°C). It may be due to attainment of an early dynamic equilibrium O2 and CO2 concentrations which were much close to the targeted level. The shelf life of mango under control, passive and active condition was found to be 4, 10 and 14 days, respectively. The extra shelf life gained by mango under active MAS condition may provide buffer period for storage, retailing and distribution during supply chain. Novelty impact statement The main cause of post‐harvest loss of crop like mango and other fresh produce is the poor handling due to unavailability of a bulk storage system at on‐farm level. Therefore, it is essential to develop an economical storage system which can facilitate large quantity storage of mango to the farmers at their orchard level itself. Hence, in the above context, our study is an attempt made to develop, design and compare an active as well as passive MAS system for mango. These uniquely developed and designed MAS systems were evaluated under passive as well as active condition by storing 100 kg of mango inside them. From the results, it was quite clear that an active MAS system can provide long‐term storage of mango even at on‐farm storage condition and can also facilitate a buffer period to the farmers during retailing and distribution.

Design of a modified atmosphere packaging for apple using concept of mathematical modeling for phytochemicals stability and shelf‐life enhancement

“…The respiration rate of fresh produce is influenced by numerous external factors, including temperature, time, CO 2 concentration and oxygen concentration (Mahajan & Caleb, 2017; Thakur et al, 2022). In order to predict the respiration rate of fresh produce, including apples, a mathematical model was created using the principles of enzyme kinetics with uncompetitive type inhibition (Ghosh & Dash, 2020; Sousa‐Gallagher & Mahajan, 2013; Thakur & Mangaraj, 2022).…”

“…Since, the gas transmission rates (OTR/CTR) of certain film laminates used for developing MAP systems rely on temperature, the Arrhenius equations of the type given in Equation (8) were used to establish the relationship between gas transmission rates (GTR) and temperature (Mangaraj, Goswami, & Panda, 2015a). By fitting the experimental data gathered for gas transmission in the linearized form of Equation (8) as presented in Equation (9), it was possible to model film permeability (Thakur et al, 2022). …”

“…Thereby, in that case the control of respiration rates of apple fruits is much crucial for better shelf life and market value. Techniques like cold storage, controlled atmosphere (CA), and modified atmosphere packaging (MAP) are mostly used to extend the shelf life of products based on the regulation of the respiration rate (Thakur et al, 2022). Though the cold storage facility is recommended for storage of apple but, it is not frequently available specially, during transportation.…”

“…As a result, the MAP is currently the most extensively used fruit preservation technique (Mangaraj et al, 2012). A MAP system is a method of food preservation in which the interior atmosphere of the package is changed to a level of oxygen and carbon dioxide concentration that is ideal for increasing the shelf life of fruits while preserving their natural quality and freshness for prolonged period of time (Mangaraj et al, 2021; Thakur et al, 2022).…”
