Effect of Coconut Flour on Biscuit Quality

Abstract

ABSTRACT This study investigated the effect of coconut flour at 10, 20, 30, 40, and 50% on the physical, chemical, sensory properties, and consumer acceptance of biscuit products. Coconut flour after drying at 60°C for 13 hours had moisture content of 1.25% and water activity values (aw) of 0.40 ± 0.01. Increasing coconut flour content significantly decreased biscuit width, thickness, weight, hardness, and brittleness (p ≤ 0.05). However, dietary fiber, roughness, coconut odor, coconut flavor, crumbliness, crispiness, and being hard to swallow significantly increased with increasing coconut flour (p ≤ 0.05). The coconut flour level up to 40% produced the highest score on biscuit flavor, biscuit odor, crumbliness, hardness, and overall acceptance.
