Thailand produces over 1.2 million tons of bananas annually, generating substantial agricultural waste — particularly banana blossoms, which are highly nutritious, rich in dietary fiber and antioxidants, yet are commonly discarded. This study aimed to develop a "fiber-enriched baked snack using banana blossom powder" to add value to this underutilized raw material and meet the growing demand of health-conscious consumers. The prototype product received second runner-up recognition at the Conovative Award 2024. However, limitations were identified in terms of coarse texture, dark coloration, and residual astringency. This research therefore focuses on optimizing the pretreatment process through safe physical and chemical methods, alongside a comparative evaluation of drying techniques — including hot-air drying, freeze drying, and microwave drying — to maximize the retention of nutritional value and bioactive compounds. The findings are expected to enhance the applicability of banana blossom powder in health food products, particularly snacks requiring refined physical and sensory qualities, and to support further commercial development.
