Abstract
Effect of various storage temperatures (13, 20, 27 and 34 °C) on biochemical, physical and physiological changes of mango fruits (Mangifera indica cv. ‘Nam Dok Mai Si Thong’) was investigated. Mangoes stored at low temperature revealed a decrease in their respiration rates. The lower respiration rates delayed ripening, ethylene production, weight loss, peel and flesh color changes, firmness, and total soluble solid content (SSC) as well as titratable acidity (TA). A second-order kinetic model, a Gaussian model, and a first-order kinetic model fitted well with response quality parameters on firmness, SSC and TA. The Arrhenius function was used to calculate the activation energies (Ea) of mango qualities including firmness, SSC and TA, which were 46.45, 43.05 and 54.22 kJ mol-1, respectively. These activation energies indicate a moderate temperature sensitivity of ripeness response and represent a good predictive tool for mango quality estimation along the food supply chain. The data reveal that stored mango fruit at 13 °C effectively prolongs the quality attributes and extends the shelf life of mango fruit.
Highlights
IntroductionNam Dok Mai Si Thong is one of the leading export products of Thailand
When the storage period was prolonged, the weight loss linearly increased during all the storage temperatures
With decreasing storage temperatures from 34 to 13 °C, the rate of weight loss obviously decreased from 2.25% to 0.46% per day
Summary
Nam Dok Mai Si Thong is one of the leading export products of Thailand. The quality and postharvest life of mango fruit depend on the harvesting time (Baloch & Bibi, 2012). The mango fruit continues to ripen rapidly after harvest (Zheng et al, 2007; Sothornvit & Rodsamran, 2008). The rate of ripening depends on the storage conditions, mainly the temperature. The minimum temperature for storage of most tropical fruits is determined by their susceptibility to chilling injury. The optimum storage temperature of a mature-green mango is 12-14 °C (Mitra & Baldwin, 1997; Sivakumar et al, 2011).
