Effect of different coatings on total soluble solids (brix) in okra samples during different storage periods.

Coating Material	Storage Duration (Days)
	0	4	8	12
Control (uncoated LDPE)	4.7 ± 0.8 a,x	3.6 ± 0.5 b,x	5.5 ± 1.0 a,x	7.0 ± 0.6 a
Chitosan coating	4.7 ± 0.8 a,x	4.8 ± 0.9 a,y	4.9 ± 0.4 a,x	6.0 ± 0.5 ab
Chitosan/ZnO coating	4.7 ± 0.8 a,y	5.3 ± 0.4 a,x	5.3 ± 0.2 a,y	5.5 ± 0.1 b

Note: ± = standard deviation; Values followed by the same letters in a column (a,b) or in a row (x,y) do not differ significantly.
