Studying On Post Harvest Quality of Five Different Mango Varieties

1. Union of MyanmarMinistry of Agriculture and IrrigationMyanma Agriculture Service Studying On Post Harvest Quality of Five Different Mango Varieties Presented by Tin Moe Hlaing

2. Objectives • to investigate proper treatment in controlling diseases including longer shelf life • to transfer technologies to the growers according to our results

3. Materials and Methods • conduct from fourth week of May to first week of June • five different mango varieties were selected • Yin Kawe, MyaKyauk, ShweHinThar, Sein Ta Lone and Nam Doc Mai. • mangoes were washed to reduce contamination & to remove any sap residue • stems were cut off ¼ in (6 mm)

4. 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˚ C

5. Treatments T1: Control T2: Benomyl (0.1 %) T3: Benomyl (0.1 %) + HWT at 60˚C for 30 seconds T4 : HWT at 60˚C for 30 seconds T5 : Thin plastic package with holes T6: Thick plastic package with holes

7. Product Quality Evaluation • Color (Outer and Inner) • Weight loss % • Firmness • Damage • Sweetness ( ˚ Brix ) • Sourness ( Acidity %)

22. Result and Discussion • Yin Kawe variety - the longest shelf life ( eleven days ) • other four varieties - seven to eight days

23. YIN KAWE • Benomyl (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 (% )

24. Yin Kwae

25. MYA KYAUK • Benomyl (0.1%) and thick package - longest shelf life • Thin package - lowest weight loss • Benomyl (0.1%) - most sweetness ( ˚Brix ) • Thin package - lowest sweetness ( ˚Brix ) • Thick package - highest acidity (%) • Benomyl (0.1%) + HWT - lowest acidity (% )

26. Mya Kyauk

27. SHWE HIN THAR • Benomyl (0.1%) and thick package - longest shelf life • Benomyl (0.1%) - lowest weight loss • Thick package - lowest sweetness ( ˚Brix ) • Thick package - highest acidity (%) • Benomyl (0.1%) + HWT - lowest acidity (% )

28. Shwe Hinthar

29. SEIN TA LONE • Benomyl (0.1%) + HWT - longest shelf life • Thin package - lowest weight loss • Hot Water Treatment - most sweetness ( ˚Brix ) • Thin package - lowest sweetness ( ˚Brix ) • Benomyl (0.1%) + HWT - highest acidity (%) • Hot Water Treatment - lowest acidity (% )

30. Sein Ta Lone

31. NAM DOC MAI • Thick package - longest shelf life • Thin package - lowest weight loss • Benomyl (0.1%) + HWT - most sweetness ( ˚Brix ) • Thick package - lowest sweetness ( ˚Brix ) • Thick package - highest acidity (%) • Hot Water Treatment - lowest acidity (% )

35. Conclusion Longest shelf life - • Yin Kawe - Benomyl (0.1 %) & Thick Package • MyaKyauk - Benomyl (0.1 %) & Thick Package • ShweHinThar - Benomyl (0.1 %) & Thick Package • Sein Ta Lone - Benomyl (0.1 %) + HWT • Nam Doc Mai - Thick Package

36. Constraints • Poor infrastructure • Insufficient skillful manpower resources • Insufficiency of cold storage system • High cost of chemicals

37. Recommendations • 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
