Abstract:
This study investigated the incorporation of Palmyra Tuber Flour (PTF), a sustainable,
gluten-free, and nutrient-dense ingredient, into instant pizzadough formulations to address
growing consumer demand for healthier convenience foods. The research focused on
overcoming technical challenges such as texture alteration, hydration imbalances, and
microbial stability while optimizing dough quality. Five dough formulations with varying
wheat flour to PTF ratios such as, 70g:30g (T1),609:409(T2),50g:50g (T3),409:609 (Ta)
and 30g:70g (T5) were developed, tested for composition (moisture: 30.78 gll00g:.
ash: 1.81 g/100g), and evaluated by trained sensory panels. Results revealed that,T2 (50g
of PTF) achieved superior sensory scores (5/5 in taste, texture, and overall acceptability),
attributed to balanced hydration and optimal dough elasticity. However, microbial analysis
indicated elevated aerobic plate counts (2.3x106 CFU/g), highlighting food safety risks
linked to high moisture content and storage conditions. PTF's high hber, low glycemic
index, and mineral-rich profile position it as a viable wheat alternative, though formulation
adjustments are critical to mitigate microbial growth and ensure structural integrity. The
study underscores PTF's potential in gluten-free pizza dough systems but emphasizes the
need for improved processing hygiene, preservative strategies, and consumer-driven flavor
optimization. These findings contribute to advancing sustainable food innovation by
leveraging underutilized crops while aligning with global health and convenience trends
