Studying On Post Harvest Quality of Five Different Mango Varieties
Presented by
Tin Moe HlaingUnion of MyanmarMinistry of Agriculture and IrrigationMyanma Agriculture ServiceObjectives to investigate proper treatment in controlling diseases including longer shelf life
to transfer technologies to the growers according to our results2Materials and Methodsconduct from fourth week of May to first week of June
five different mango varieties were selected
Yin Kawe, Mya Kyauk, Shwe Hin Thar, Sein Ta Lone and Nam Doc Mai.
mangoes were washed to reduce contamination & to remove any sap residue
stems were cut off in (6 mm)3 conduct at the vegetable and fruit research and development center (VFRDC)
14.9 meter high above sea level
annual rainfall is 2070 mm
maximum temperature 31.30 C
minimum temperature 16.10 C4TreatmentsT1 : Control
T2 : Benomyl (0.1 %)
T3 : Benomyl (0.1 %) + HWT at 60C for 30 seconds
T4 : HWT at 60C for 30 seconds
T5 : Thin plastic package with holes
T6 : Thick plastic package with holes

21Result and Discussion Yin Kawe variety - the longest shelf life ( eleven days )
other four varieties - seven to eight days22YIN KAWEBenomyl (0.1%) - lowest weight loss
Benomyl (0.1%) - most sweetness ( Brix )
Thin package - lowest sweetness ( Brix )
Thick package - highest acidity (%)
Hot water treatment lowest acidity (% )
23Yin Kwae

ConclusionLongest shelf life - Yin Kawe - Benomyl (0.1 %) & Thick Package
Mya Kyauk- Benomyl (0.1 %) & Thick Package
Shwe Hin Thar- Benomyl (0.1 %) & Thick Package
Sein Ta Lone- Benomyl (0.1 %) + HWT
Nam Doc Mai- Thick Package
35Constraints Poor infrastructure
Insufficient skillful manpower resources
Insufficiency of cold storage system
High cost of chemicals
36Recommendations Factor affecting the shelf life of stored fruits is the time of harvesting
Which DAF is the best harvesting time for Mango
Make the growers more efficient and less costly
Possible simple and inexpensive cooling procedures
