| Abstract | A study to model t he effect of temperature on handling and storage of mango was made . Studies were conducted at various constant storage temperatures namely 13 °C, 20 °c and 30 °C for fruits exposed to different initial temperature treatments (i.e., precooled at 13°C and 20 °C and heated to 35 °C and 40 °C). corresponding to conditions prevailing in the field . Two other sets of experiments were conducted to study the effect of high temperatures and the effect of varying temperature on fruit. The studied properties were weight loss, respiratory rate, firmness, pn , 0 Brix and chlorophyll. The results show a definite effect of storage temperature and days of storage on fruit property variation. The effect of treatment temperature was sta l-istically significant at 95% confidence level, for weight loss, firmness, p11 and 0 Bri x and not significantly different in the case of respiration rate and chlorophyll degradation. An initial linear relationship was observed between the respiration rate of mango and storage temperature from 13 °c to 30 °C. The climacteri c respiratory rate can be taken as an index for storage life of fruit . The phenomenon of delayed ripening was observed above 35 °c affecting normal property variation . Non-linear regression equations were developed with storage temperature, treatment temperature and days of storage as independent variable and properties as dependent variables. Models for weight loss, respiration rate and firmness are included. An exponential relationship was developed for predicting shelf life of mango, at a given temperature. The models were used to predict the different property changes of fruits at given storage environments. |
