Abstract
Currently there is a growing demand for fiber fortified food products in the world to prevent from non-communicable diseases. To develop high fiber soft dough biscuit, kohila flour was added to biscuit formulation at 10% and 15% levels (w/w), respectively. Sugar was substituted with sucralose (1 g) to obtain a low energy product. The chemical and proximate compositions of the product (moisture, pH, protein, fat, ash, dietary fiber, carbohydrate, sodium and heavy metal, antioxidant capacity) were determined. Sensory evaluation was carried out by a panel of thirty semi trained panelists, using a paired preference test and hedonic test to select the most preferred sample with the best sensory attributes. A market survey was done by using sixty sample sizes to evaluate the consumer preference for the prepared biscuit. Results showed that kohila flour fortified biscuits contained significantly (p<0.05) high amount of fiber (7% (w/w), on dry basis). High amount of iron (48% ppm, dry basis) contained in fortified biscuits while none of the toxic heavy metals (As, Pb and Cd) were absent. The antioxidant capacity (Radical DPHH scavenging capacity) was as high in kohila flour added biscuits (20-23%). The 10% kohila flour added biscuits yielded the highest consumer acceptability. Survey results showed that there was a correlation between preference for sucralose added biscuits and health condition (p<0.05) of the consumers. The preference for fiber fortified biscuits and sucralose added biscuit were high in consumers with higher level of education. Findings of this study revealed that 10% kohila flour fortified biscuits can be used as a rich source of dietary fiber which was beneficial to improve the health of the consumers.

Summary
Non communicable diseases (NCDs), together with injuries and violence, are causing about 60% deaths worldwide. Strong evidence shows that an unhealthy diet and insufficient physical activity are among major causal factors in NCDs such as coronary heart diseases, ceribrovascular strokes, several forms of cancers, type 2 diabetes, hypertension, obesity, osteoporosis, dental caries and other conditions, Such unhealthy diets include high amount of salt, fat, sugar and less dietary fiber (DF). Dietary fiber has a protective action against various health disorders such as diabetes mellitus, cardiovascular diseases, constipation, appendicitis, hemorrhoids, and colon cancer [6,7]. There has been increasing interest in the use of natural food additives and incorporation of health promoting substances into the diet as dietary fiber [9]
