rest of the treatments. The total phenols content was significantly affected by different
treatments during entire storage period. The minimum reduction (11.62%) in total phenols
content was found that Sodium Nitro Prusside @ 2.0 mM), while it was maximum (21.94%)
in fruits under control (on 9 th day of storage). Coating with Sodium Nitro Prusside @ 2.0 mM)
was found significantly at par with Salicylic acid @ 1.5 mM (11.81%). The antioxidant activity
was significantly affected by different treatments during entire storage period. The minimum
reduction (34.75%) in antioxidant activity was found with Sodium Nitro Prusside @ 2.0 mM,
while it was maximum (85.71%) in fruits under control (on 9 th day of storage). However,
Sodium Nitro Prusside @ 2.0 mM was found superior over all other treatments. Similar
findings were also observed by Ghasil, et.al. (2022)
Conclusion
On the basis of results obtained in the present research experiment, it may be concluded that
coating with Sodium Nitro Prusside @ 2.0 mM was found significantly superior over all other
treatments and it also observed in maintaining the quality and extending the shelf life of
Balanagar custard apple fruits. Further, under this treatment recorded highest TSS
(38.87°Brix), maximum increment of total sugar (70.26%), highest ascorbic acid (43.20
mg/100g), minimum reduction of phenol content (11.62%) and highest antioxidant capacity
(0.92 μmol Trolox/100 g) end of the storage period. However, Sodium Nitro Prusside @ 2.0
mM) was found best for maintaining biochemical and functional activities and increased the
shelf life up to 8 days of storage at room temperature.
