Measurement and Modeling of Respiration Rate of Guava (CV. Baruipur) for Modified Atmosphere Packaging

Abstract

Several experiments were conducted at different storage temperatures for generating respiration data using close system method for respiration. A respiration rate model, based on enzyme kinetics and the Arrhenius equation was proposed for predicting the respiration rates of Guava as a function of O 2 and CO 2 concentrations and storage temperature. Temperature was found to influence the model parameters. In this model, the dependence of respiration rate on O 2 and CO 2 was found to follow the uncompetitive inhibition. The enzyme kinetic model parameters, calculated from the respiration rate at different O 2 and CO 2 concentration were used to fit the Arrhenius equation against different storage temperature. The activation energy and respiration pre-exponential factor were used to predict the model parameters of enzyme kinetics at any storage temperature between 0-30 • C. The developed models were tested for its validity at 12 • C and it was found to be in good agreement (the mean relative deviation moduli between the predicted and experimental respiration rates were found to be 8.95% and 8.02% for O 2 consumption and CO 2 evolution, respectively) with the experimentally estimated respiration rates.

Design and development of modified atmosphere packaging system for guava (cv. Baruipur)

“…2). These results are in close agreement with those obtained by Talasila et al (1992), Mangaraj and Goswami (2011a).…”

“…(Jacomino et al 2001a). The need of postharvest management of guava fruit in a scientific way like CA/MAP storage was realized to extend its period of availability in market and also to harness the export opportunities (Mangaraj and Goswami 2011a). MAP technology has the potential to reduce the weight loss, maintained firmness, preserve colour and alleviated chilling injury of guava fruits by controlling the overall metabolic activities (Jacomino et al 2001a;Mohamed et al 1994;Sunjka et al 2003).…”
