“…The dependence of respiration rate on the headspace O 2 and CO 2 concentrations has been described assuming the enzyme kinetics model for combined type of inhibition proposed by Peppelenbos and Van't Leven (1996). The effect of surrounding temperature on the respiratory parameters has been evaluated using the Arrhenius relationship (Fonseca et al 2002;Benkeblia 2004;Charles et al 2005;Kaur et al 2011). The changes in the respiratory parameters on account of minimal processing have also been discussed.…”

“…A two to three fold increase in biological reactions has been reported for every 10°C rise in temperature within the range of temperatures normally encountered in the distribution and marketing chain. Arrhenius law has been widely used to describe temperature dependence of respiration rates (Fonseca et al 2002;Kaur et al 2011;Benkeblia 2004;Charles et al 2005). All the parameters of enzyme kinetics model were evaluated using Arrhenius law [ k ¼ Ae ÀEa RT ] to study the effect of storage temperature.…”

The respiratory behaviour of baby corn -whole and end-cut, under different temperatures and gas conditions was evaluated to study its respiratory dynamics based upon enzyme kinetics. The dependence of respiration rate on the O 2 and CO 2 concentrations has been described assuming the enzyme kinetics model for combined type of inhibition caused by CO 2 . Various respiratory parameters viz. maximal O 2 consumption rate Michaelis-Menten constants, Inhibition constants under the specified environmental conditions of 5, 12.5, 20°C and 75% relative humidity (RH) were estimated using non-linear regression technique. The enzyme kinetics parameters were analyzed according to Arrhenius law to study their temperature dependence. Based upon the overall analysis, it was found that storage temperature had substantial affect on the partial pressures within the closed containers and subsequently the respiration rates. The concentration of O 2 inside the container and surrounding temperature had synergistic effect on the rate of respiration and respiratory parameters. Though the inhibition by evolved CO 2 was observed to be of combined type, it changed from predominantly competitive at 5°C to predominantly uncompetitive at 12.5 and 20°C. This study can be utilized for design of modified atmosphere packages for storage of fresh and minimally processed baby corn.

The respiratory behavior of fresh‐cut spinach under different temperatures and gas conditions was evaluated to develop an integrated respiration model taking into account the temperature dependence of enzyme kinetics parameters. The dependence of respiration rate on the O2 and CO2 concentrations has been described assuming the enzyme kinetics model for combined type of inhibition caused by CO2. The respiration model parameters under the specified environmental conditions of 10, 15, 20C and 75% relative humidity were estimated using non‐linear regression technique and were utilized to predict the rates of respiration for O2 consumption and CO2 evolution. Mixed type of inhibition was observed at all the temperatures, but changed from predominantly competitive at 10 and 15C to predominantly uncompetitive at 20C. The enzyme kinetics parameters were analyzed according to Arrhenius law, as well as simple linear and polynomial equations to determine relationships for describing their temperature dependence. The final integrated model encompassed the effect of headspace gaseous concentrations, CO2 inhibition, surrounding temperature, and can be utilized for respiratory and shelf‐life studies of different fruits and vegetables. PRACTICAL APPLICATIONS Fresh‐cut spinach leaves have an enormous market around the world owing to their high nutritive value. Shelf life and quality of fresh‐cut produce may be greatly reduced due to high rates of respiration. Traditional packaging, handling, storage and transportation techniques reduce the shelf life and various nutritional and phytochemical components of fresh‐cut produce. Temperature control and atmospheric modifications (low O2: 1–5% and high CO2: 5–10%) help to maintain produce quality by reducing respiration rate and enhance shelf‐life by minimizing the adverse effects of cutting in fruits and vegetables. This research has focused on determination of respiratory behavior of fresh‐cut spinach leaves at temperatures commonly encountered during transportation and retail distribution i.e., 10–15C. The results of the study show the potential of use of modified atmosphere packaging for packaging of fresh‐cut spinach leaves. Utilization of the results of this research would be of immense help in developing a user friendly program for simulating in‐pack gaseous conditions by varying the experimental parameters and in proper designing of modified atmosphere packages for storage and transportation to retail markets.

Onion is one of the most cultivated crops and its production is increasing worldwide. Proper handling and storage will add huge benefits to the supply of onion to meet the demand of consumers. For storage, it is important to understand onion physiology from the day it has been harvested from the field until it reaches the market. This review summarizes the scientific literature related to the physiology of the onion bulb with respect to growth regulators, temperature, and chemical controls. The biochemical changes that occur during dormancy break and sprouting have been discussed in detail. The three main environmental factors that can influence onions during storage are temperature, humidity and composition of the atmosphere in the storage area. Among these factors, temperature plays a paramount role in the physiology of onion during pre-and postharvest storage. Particular emphasis was given to plant growth A c c e p t e d M a n u s c r i p t 2 hormones (endogenous and exogenous) and their consequent effects with respect to dormancy, sprouting and biochemical changes that occur in onions.
