|Abstract: ||Corn starch constitutes a hydrocolloid characterized material to be used in
the edible film preparation. Research on starch has been conducted before to
acknowledge physical nature of produced edible film. Improving its functional
nature instead of being packager, research considers tomato filtrate as natural
antioxidant in the edible film. The weakness of this starch based edible film relates
to its susceptibility to torn due to mechanic treatment, and therefore, it needs
glycerol as its plasticizer. The objective of this research will be to understand the
appropriate concentration of corn starch and glycerol and to examine the activity
of natural antioxidant in the additional tomato filtrate as antioxidant.
Research employs Complete Random Planning with 2 factors. Factor I
includes corn starch concentration arranging in three levels (1.25%; 1.5%; 1.75%
v/wtotal). Factor II may be glycerol concentration consisting three levels (0.1%;
0.2%; 0.3% v/wtotal) with 3 replications. Data seem analyzed using variance
analysis (Anova). Further test has been conducted with obvious differential test
(BNT) and DMRT by 1 % and 5 % intervals of trust. The determination of best
treatment utilizes Zeleny method. The comparison of best treatment with other
product can be conducted using t-test.
Results of research show that the treatment of corn starch combination has
obvious effect (α=0.05) against all physical and chemical characters of edible
film, such as antioxidant activity, water content, elongation, tensile strength,
thickness, color, water permeability, and water vapor transmission rate. Glycerol
has obvious effect on water content, elongation, tensile strength, water vapor
transmission rate, thickness, water permeability, and color (brightness).
The best treatment develops from the combination of corn starch
concentration of 1.5 % v/wtotal and glycerol of 0.3 % v/wtotal (P2G3) with 35 %
water content, 80.61 % antioxidant activity, 0.13 mm thickness, 4.74 kPa tensile
strength, 18.42 % elongation, 0.44 g/m
per hour for water vapor transmission
rate, 65.9 % water permeability, and 64.2 for brightness.
The comparison of the best treatment and the edible film from ginger
candy product shows obvious different result (α=0.05) against all physical
parameters of edible film such as water content, thickness, tensile strength,
elongation, water vapor transmission rate, water permeability, and color.
The application of edible film in the apple pudding indicates obvious
effect (α=0.05) on TBA number of apple pudding due to packaging treatment.
Rancidity rate of apple pudding packaged in the edible film refers to the lowest|
