Abstract:
An experiment was carried out at the laboratory of Department of Horticulture,
Sher-e-Bangla Agricultural University, Dhaka to study the effect of organic
coatings on shelf-life and postharvest quality of banana. The experiment consists
of two factors as varieties viz. (i) V
1
: Amritsagar and (ii) V
: Sabri and six organic
coating treatments viz. (i) T
0
: Control, (ii) T
1
2
: Aloe-vera gel, (iii) T
:Ginger oil,
(iv) T
3
: Garlic extract, (v) T
4
: Onion extract and (vi) T
: Neem extract. The twofactor
experiment was laid out in completely randomized design with three
replications. The collected data on various parameters were statistically analyzed.
The experiment was continued to 12 Days After Storage (DAS) from sample
collection. Results revealed that among two varieties, V
5
(Sabri) showed the
highest shelf life (10.3 days) where V
1
2
(Amritsagar) showed (9.2 days). Among
the different treatments, T
(Aloe-vera gel) treatment gave the best performance
(11.7 days) on shelf life compared to control. In terms of combination effect V
1
(Sabri) with T
1
(Aloe-vera gel) treatment (V
2
T
) gave the highest shelf life(12.0
days). It also gave the lowest total weight loss (8.1%), highest moisture content
(65.7%), lowest TSS (34.5%) and lowest pulp to peel ratio (3.8) and also lowest
diseases incidence and severity of banana during postharvest storage.
