FUNCTIONAL PROPERTIES AND INFLUENCES OF COCONUT FLOUR ON TEXTURE OF DOUGH AND COOKIES

Abstract

Coconut flour, a significant byproduct of coconut milk and oil productions, is rich in fiber and protein. It can be utilized as an alternative material for cookies products. This paper focused on the functional properties of coconut flour and effect of coconut flour supplement on texture of dough and cookies. Results indicated that hydration properties and oil binding capacity (OBC) were significantly influenced by size of particles in coconut flour. With increase in size of coconut flour, water absorption capacity (WAC) and swelling capacity (SC) values increased; whereas, OBC value decreased. Maximum value of water retention capacity (WRC) was observed at 0.20–0.25 mm of particle size. Adding coconut flour into dough caused enhancement of hardness, cohesiveness and adhesiveness; whereas, insignificantly influenced on springiness. In addition, adding coconut flour led to decrease in spread ratio and increase in hardness of cookies. The results can be applied for substitution of coconut flour for wheat flour in cookies processing.
