Abstract

Sesbania grandiflora is plant cultivated for its edible flowers in all over India. It's edible flowers and leaves has unique medicinal properties and used as a herbal drug for its antibiotic, anthelmintic and anti-tumor properties. The plant contains rich in phytochemicals such as polyphenols, flavonoids, carotenoids, tannins, steroids and triterpens having antioxidant, anticancer properties and used in colic disorder, jaundice, poisoning condition, small-pox, eruptive fever, epilepsy. Sesbania grandiflora flowers and leaves was underutilized vegetable because of seasonal availability and perishability. In present investigation efforts have taken to prepare powder from S. grandiflora flower and leaves to enhance its utilization. For preparation of powder flower and leaves subjected to different pre-treatments (without blanching, blanching and blanching + sulphitation). The effect of pre-treatment on drying characteristics flower and leaves was studied. Further effect of pre-treatment on physical, functional and reconstitutional properties of flower and leaves powder were investigated. The data obtained revealed that there is remarkable decrease in the drying time of blanched and blanched + sulphited flower and leaves. The results on colour attributes of flower and leaves powder show increase in lightness ie L* value and reduction in the a*and b* value in blanched + sulphited sample than control. In particle size analysis of powder the blanching + sulphitation treatment show the higher percentage on 80, 60 and 30 mesh sieve compared to other treatment. The data on functional properties of flower and leaves powder indicate that the highest bulk density, water absorption capacity, oil absorption capacity and swelling power was recorded in blanched sample FP1 and LP1. The treatment blanching + sulphitation show positive effect on solubility and wettability too. The findings of present investigation revealed that Sesbania grandiflora flower and leaves powder prepared by blanching + sulphitation treatment have better physical, functional and reconstitutional properties. The developed powder could be utilized in different value added product for fortification to improve its nutritional and phytochemical value.

Conclusion

Data on the effect of pretreatments (without blanching, blanching and blanching + sulphitation) on drying characteristic revealed there is remarkable decrease in the drying time of blanched and blanched + sulphited Sesbania grandiflora flower and leaves. Effect of pre-treatments on colour attributes of Sesbania grandiflora flower and leaves powder show increase in lightness i.e. L* value and reduction in the a*and b* value in treated sample which imparts attractive brightness to powder. The powder prepared by blanching + sulphitation treatment received the higher percentage on 80, 60 and 30 mesh sieve having pore size 180, 250 and 300 μm pore size. The maximum flower powder retained 43.50 per cent and leaves powder 43.05 per cent on 80 mesh sieve. The pre-treatments blanching + sulphitation results in to improvement in functional as well as reconstitutional properties of Sesbania grandiflora flower and leaves powder. It can be concluded from present investigation that the treatment blanching + sulphitation was suitable for both Sesbania grandiflora flower and leaves powder preparation. As per earlier studies reported Sesbania grandiflora flower and leaves had nutritional, medicinal and therapeutic significance hence the developed flower and leaves powder would be utilized in different value added products for improving its nutritional and functional value.
