The sensory score of mango milk drink prepared from stored
reconstituted MMP was significantly different from those of the samples
prepared from fresh MMP.
These results are consistent with those reported by Radayevamet al.
[34]; the flavor scores of reconstituted mango milk drink decreased
steadily with the progress of storage period. The rate of deterioration
was faster at 30 °C than at 5 °C. The rate of deterioration was slightly
faster in samples packed in polystyrene than those packed inmetalized
polyester, 4-ply laminates and tins. The rapid decline in flavor scores
after 5 months storage could be expected due to oxidative changes.
The body and texture score also decreased with increased storage
period. There was a steady reduction in color and appearance scores
of mango milk prepared from progressively stored MMP. Reduction
in color and appearance may be due to oxidation of pigments.
The statistical analysis has shown that tin can has significant difference
as compared to other packaging material because the difference
between the mean value of tin can and other treatment is more than
the critical difference (CD) value.
