The color parameters (L*, C* and h*) of capsicum in different
treatments are tabulated in Table 7. The lightness (L*) of the
fresh whole capsicum on the initial day was 34.3. The L* values
were significantly reduced in both CS and CR samples.
Whereas, both the AMAP and MAP treatments observed very
minimal L* value and did not changed significantly by the end
of day 49 and day 42, respectively. The initial chroma (C*) value
was 19.61 in fresh capsicum. The C* values (intensity of green
color) were significantly reduced to 35.21% in CS and 20.21% in
CR treatments from initial value by the end of day 49 and day
42 of storage, respectively. However, AMAP and MAP treatment
had non-significant in-between differences (Table 6).
The AMAP samples exhibited the lowest, chroma reduction
which was 5.13% followed by 7.38% in MAP sample by the end
of their respective storage period (42–49 days). The initial hue
angle (h*) was 119.51 and presented non-significant variations
in AMAP and MAP samples throughout the storage. However, a
significant difference in h* value was noticed in CS and CR
treatments by the end of day 21 and day 35, respectively. Both
the AMAP and MAP samples had low L* or high h* angle values
at the end of the storage, indicated retention of the initial
green color which may be due to limited dehydration and/or
limited chlorophyll degradation which is responsible for the
green color. In both the cases, the small L* reduction (
