Development Of A Functional Beverage Using Bitter Melon (Momordica charantia L.) Juice
Bitter melon (Momordica Charantia L., BM) is one of the medical vegetables and has been used for anti-diabetes treatment for decades. This study has compared two BM varieties which are popular on the North American market, Indian and Chinese BM, on total phenolic content (TPC), total triterpene content (TTC), antioxidant activities, anti-diabetic properties, and anti-inflammatory effects. The Indian BM which has shown superior properties was used for developing an encapsulated bitter melon juice (BMJ) powder using spray drying. Shelf life and sensory properties of the developed powder drink was evaluated. The encapsulation formulas were evaluated by parameters like encapsulation efficiency (EE), antioxidant activities, and anti-diabetic properties. The juice powder, formulated with pectin and gum Arabic, performed better in terms of EE and α-Amylase inhibition effect. The powder drink formulated with pectin and soybean protein isolate was further compared with a commercial BM beverage on market on their sensory properties. The results have shown that the developed powder drink exhibited less sourness, more appealing aroma, no precipitation phenomenon, and ease care of storage compared with the commercial BM beverage. The results indicated a promising future of the BM powder drink developed in the current study.
