Surfactants Augment Postharvest Pressure Infiltration of Calcium into `Golden Delicious' Apples

Heat Treatment Affects Epicuticular Wax Structure and Postharvest Calcium Uptake in 'Golden Delicious' Apples

‘Golden Delicious’ apples (Malus domestica Borkh) were pressure-infiltrated at harvest with a 4% CaCl2 solution either without prior heat treatment or following 4 days at 38C. Examination of the apple surfaces from both treatments by low-temperature scanning electron microscopy revealed that heat treatment changed the pattern of epicuticular wax. The epicuticular wax of nonheated fruit exhibite...

postharvest application of calcium carbonate nanoparticles on enzyme activity and some attributes quality in fresh cut apples varieties golden delicious

introduction: nowadays, due to mechanization of life, consumers need of food which they spent little time for preparation, so fresh cut industry is growing rapidly in the world. these products had strong growth since 1940, and in 2013, most sales of fresh cut fruit related to apples, against 21.8 percent. minimal processing operations include grading, washing, sorting, slicing, chopping and the...

Chemical changes in the cortical tissue and cell walls of calcium-infiltrated ‘Golden Delicious’ apples during storage

‘Golden Delicious’ apples (Malus /domestica Borkh.) were either untreated or pressure-infiltrated after harvest with 0, 1, 2, 3 or 4% CaCl2 solutions (w/v) and stored at 0 8C for up to 6 months. The chemical composition of the fruit cortical tissue and cell walls of the 2 /4 mm layer under the epidermis was studied. Storage of untreated fruit resulted in a decrease in K, P, Mg, S and Suc conten...
