The
retention of green colour in the modified atmosphere (MA)
packed chillies may be due to reduced respiration rate caused by
modified atmosphere within the package. Slow respiration rate
resulted in restricted breakdown of chlorophyll and decreased
the rate of synthesis of carotenoids, which occur during
senescence process. The chlorophyll and carotenoid contents
of chillies can also vary in composition and concentration
owing to differences in genetics and maturation
