This innovation transforms Thai Kluai Hin and Namwa bananas into functional ingredients: low-GI green banana flour and zero-waste peel powder. Research identifies Kluai Hin as superior, boasting 52% resistant starch. The prototype, a crispy waffle using 10% peel powder, delivers a "Source of Dietary Fiber" with 1.6x more resistant starch than wheat versions. This sustainable solution creates mineral-rich, gut-friendly snacks from agricultural surplus.
