Abstract

The dietary fiber contents of Common Laguna and Laguna Purple (Purple) coconut "sepal" at different portions of the coconut cluster were estimated by determination of the fiber's chief constituents which are cellulose, hemicellulose and lignin. Hemicellulose was extracted with 0.5% boiling NaOH and precipitated with alcohol with the residue determined for lignin by treatment with 67% sulfuric acid. Cellulose was determined colorimetrically. The Common Laguna variety has a significantly higher dietary fiber content with 32.72% over the purple with 26.41%. There was no significant difference in the content of the upper, middle and bottom portion of coconut cluster with 30.2016, 36.37% and 31.09%, respectively, for Common Laguna variety and 25.78%, 28.61% and 27.36%,
