Abstract

Biscuit are convenient food products, becoming very popular among both rural and urban populations of India. Some of the reasons for such wide popularity are low cost among other processed foods. India is the second largest wheat producing nation after China in the world and contributes approximately 12 per cent to the world wheat production. The principle basis of most baked products that can be regarded, as snack food is wheat flour. The flour quality is defined as ability of flour to produce uniformly good product and it will be very misleading to define the product. This may be also because of good quality of one product may not be good quality of another baked product. Fenugreek seeds are rich in carbohydrates, and especially mucilaginous fibre. This soluble fibre is comprised of galactomannas, similar to properties in that of guar gum. Fenugreek also contains a rich variety of steroid saponins and flavonoids all of these substances are known to lower blood lipid levels. Fenugreek seeds also contain 4-hydroxyisoleucine, an unusual amino acid that initiates insulin release form the pancreas. The ability of fenugreek to improve glucose tolerance is further enhanced by its rich content of soluble fibre. Biscuit prepared from the blends containing different proportions (0%, 5%, 10%, 15% and 20%) of germinated fenugreek seed flour were evaluated for width, thickness, spread ratio and sensory characteristics. The thickness of fenugreek supplemented biscuits increased, whereas width and spread ratio of biscuits decreased with the increasing level of fenugreek flour. The sensory results showed that a maximum of 10 per cent fenugreek flour can be incorporated to prepare acceptable quality biscuits. Addition of germinated fenugreek flour to wheat flour increased the content of protein (10.5%, 10.4% and 11.0%) lysine (2.15, 2.20 and 2.25 g/100 g protein), dietary fibre (12.7%, 11.3% and 10.9%) total Ca (58.3, 57.1, 57.7 mg/100 g) and total iron (7.40 ,7.26 and 7.36 mg/100g ), respectively, at 10 per cent level of substitution. These biscuits can be safely stored in polypropylene bags upto 1 month without altering their organoleptic properties.

Abstract

Supplementation of food is of current interest because of increasing nutritional awareness among consumers. Supplementation with legumes is one way to meet the protein needs particularly with the help of baked foods. Supplementation of wheat flour with green gram flour was tried at 30, 40, 50, 60 per cent levels along with sugar, skimmed milk powder, fat and baking powder to improve the nutritional and sensory quality of biscuits. Results of baked biscuits revealed that the thickness (cm) was increased and diameter (cm) was decreased up to 60 per cent level of incorporation of green gram flour. Therefore spread ratio was decreased with increased the incorporation of green gram flour in formulation. However green gram dhal flour 30-60 per cent incorporation improved protein, fat and ash content of biscuits. The value of protein and fat content was decreased during storage but value of ash content was almost constant during storage. Moisture content of fortified biscuits was more than controlled biscuits and it was increased during storage. The sensory analysis of 50 per cent green gram dhal flour incorporated biscuit up to 30 days was accepted by panel judges on the basis of nine point hedonic scale. Thus supplementation of refined wheat flour with green gram flour 30- 60 per cent level, not only improve protein quality but also improved overall acceptability and sensory parameter in final product. Two types of packaging materials, high density polyethylene and low density polyethylene was used for packaging of biscuits in which high density polyethylene was more accepted because it was less permeable to gas and moisture as well as increased the storage period of biscuits.
