Abstract:
An experiment was conducted on the aspect of quality and shelf life of mango
through postharvest preservatives and packaging. This study was carried out at
the Postharvest laboratory of Department of Horticulture, Sher-e-Bangla
Agricultural University, Dhaka. The experiment was laid out in a Completely
Randomized Design. Seven postharvest preservative treatments and two
postharvest packaging, total 14 treatments combination were used in the
present study. Different postharvest preservative treatments were T
: Control
(without preservative), T
1
: 1-methylcyclopropene (1-MCP) dips, T
: chitosan
dips, T
3
: calcium chloride dips, T
: 1-methylcyclopropene (1-MCP) dips +
chitosan dips, T
5
4
: 1-methylcyclopropene (1-MCP) dips + calcium chloride dips,
T
6
: calcium chloride + chitosan dips. Two postharvest packaging: P
: With
perforated LDPE packaging and P
: Without packaging were used. Results
revealed that the lowest weight loss was found in T

treatment (3.78%, 5.45%,
7.05%, 8.78% and 10.50% at 3

respectively) with the lowest disease incidence (%) and slower ethylene release
rate (1.94 ppm/hr., 3.94 ppm/hr. and 8.17 ppm/hr. at 3
th
, 6
th
and 9
days after
harvest, respectively) compare to other treatments. The longest shelf life (18
days) was recorded in T

P
treatment combination. The better performance was
observed in mangoes when treated with postharvest 1-methylcyclopropene (1MCP)
dips
+ chitosan dips and postharvest packaging with perforated LDPE
bags for long term storage
