Abstract:The present investigation on “Post-harvest studies in banana (
Musa paradisiaca L.)
cv. Grand Naine” was conducted during June 2021 and November 2021 at the Laboratory of Postharvest Technology, Department of Horticulture, MPKV., Rahuri, Dist. Ahmednagar. The effect of post-harvest treatment of chemicals, wax emulsion and storage conditions on shelf life and quality of banana
cv. Grand Naine was laid out with six chemical treatments
viz., C
1 - Hexanal @ 3%, C
2 - Hexanal @ 4%, C
3 - Hexanal @ 5%, C
4 - Salicylic acid @ 2mM, C
5 - Salicylic acid @ 3mM, C
6 - Salicylic acid @ 4mM, two wax emulsions
viz., W
1 - Wax emulsion @ 6%, W
2 - Wax emulsion @ 8%, two different storage conditions
viz., S
1 - Ambient temperature and S
2 - Cold storage (13 °C+1) and fruits were analyzed for physico-chemical parameters at an interval of two days.
Fruits treated with hexanal @ 3% + wax emulsion @ 8% and stored under cold storage recorded minimum PLW (9.12%), pulp to peel ratio (2.13), ripening (97.13%), spoilage (49.79%) and maximum firmness (13.02N), maximum number of days taken to colour break (9.00), maximum overall acceptability (8.64) with maximum shelf life of 24 days. At ambient conditions, treatment combination with same chemical and wax emulsion revealed maximum shelf life of 18 days. However, fruits under control recorded shelf life 8 days at ambient conditions.
