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 (% )

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
