Abstract

The preservation of mango by heat processing was studied using canned mango slices, nectar, juice and pulp. Yeast was found to be the only spoilage organism in a commercial sample of spoiled canned mango slices in syrup and had a thermal death time of 1 min at 151 degree F. Thermal inactivation time of peroxidase, which was used as the test enzyme, was 1 min at 170 degree F in mango extract and 1 min at 175 degree F in mango syrup. Process times were calculated using these as reference temp. For a 401 x 411 size can, the required processing times at 212 degree F were 7, 8, 7.5 and 5 min for slices, nectar, juice and pulp respectively. In canned mango juice and pulp there is very little temp. rise during processing. Therefore, filling temp. is very important to minimize process time and to ensure adequate thermal inactivation. A filling temp. of greater than170-175 degree F, sealing, keeping the cans inverted for 2-3 min to sterilize the lids and cooling afterwards should be sufficient to ensure adequate sterility.
