Summary : The coconut endosperm cell wall known as coconut meat fiber was isolated and studied for its physical and chemical characteristics in order to explain the nature of dietary fiber in coconut and its behavior in food formulation. With the increase in maturity, the neutral detergent fiber content of coconut flour increased in the normal varieties and decreased in the Makapuno. The acid detergent fiber increased in normal coconut while that in Makapuno did not show considerable variation as the nut matured. The total carbohydrate content of normal coconut endosperm varied from 59.95 to 77.39% at the seventh month to 71.02 to 81.04% at the twelfth month. In all the varieties studied, mannose, glucose and galactose were found to be the major sugar components of the coconut endosperm cell wall, while rhamnose, arabinose and xylose were also present. The water soluble polysaccharide of the cell wall was predominantly galactomannan with galactose and mannose occurring at a ratio of 1:2. This fraction was 38.85% greater in the Makapuno than in the mature normal nut where values ranged from 6.87 to 12.43% depending on the variety. The cell wall of the seven month-old Laguna Tall Green nut contained 22.70% of this water soluble polysaccharide.
