Abstract

Defatted coconut flour obtained from the whitish kernel residue left after the extraction of virgin coconut oil has potential application in high protein-fiber enriched food products. A study was conducted to investigate the use of defatted coconut flour in the preparation of fiber-enriched biscuits. In this, wheat flour was fortified with defatted coconut flour in varying proportions (w/w, 0, 10, 20, 30, 40, 50, 60, and 70%) to prepare a series of blends for biscuit dough. Biscuits samples prepared according to a standard recipe were evaluated by a 36-member semi-trained panel using a 7-point hedonic scale to determine the critical limit of defatted coconut flour substitution in wheat flour for acceptable quality biscuits. Results showed that defatted coconut flour could be used to substitute wheat flour up to a level of 40% without affecting the overall quality. At this level, the dietary fiber content of the biscuit was found to increase by about 10 times. Although biscuit samples showed good acceptability at the beginning, their keeping quality decreased with the increasing level of defatted coconut flour in the biscuit formulation.

Abstract

Value addition to coconut oil is highly desirable in order to increase the range of coconut products. A study was conducted to formulate palatable coconut oil (CNO) blends enriched with essential fatty acid (EFA) using sesame seed as the supplementary source of EFA. For this purpose, micro-expelling process was employed to extract oil blends out of the dried coconut grating mixed with varying proportion of sesame seed (w/w; 0, 1, 2, 3, 4, 5, 7 and 10%). A sensory evaluation by a 30-member semi-trained panel was conducted using a seven-point hedonic scale in order to determine the critical limit of CNO fortification with sesame. Similarly, changes in fatty acid composition were determined using Gas Liquid Chromatography (GLC). Statistical analysis of the sensory data showed that a mild odor of sesame started to appear in the oil blends at 4% level of sesame mixed with dried coconut gratings. According to fatty acid methyl ester (FAME) analysis, the relative increase in linoleic acid was only marginal although there was a substantial increase in unsaturated fatty acid component. At 5% level of fortification, the increment in linoleic acid was 9.2%.
