Functional Properties of Sausage Rolls Made from Cocoyam and Wheat Flour Enriched with Soybean Flour

Abstract

Functional properties of sausage rolls made from cocoyam and wheat flour enriched with soybean flour was studied. Cocoyam cormels and soybean were processed into flour, which were later used to formulate composite flour blends, with wheat flour in the ratio of: 90:10:0 (control 1), 80:10:10, 70:10:20, 60:10:40, 50:10:30, respectively, while 0:10:90 served as control 2. The result of the functional properties showed variation in behavior. There were no significant difference (p≥0.05) in pH, bulk density, swelling index, foam capacity and emulsion capacity of the flour samples while significant difference (p≤0.05) existed in water absorption capacity, oil absorption capacity and wettability.

Proximate Compositions and Functional Properties of Composite Flour Produced with Date Fruit Pulp, Toasted Watermelon Seed and Wheat

“…Composite flour can be defined as a mixture of different ratios of non-wheat flours obtained from roots and tubers, cereals, legumes, etc., with or without the addition of wheat flour [1,2]. Composite flour is considered advantageous in developing countries as it reduces the importation of wheat flour and encourages the use of locally grown food crops as flour [3].…”

“…Nigeria has not been able to produce wheat in commercial quantities because of climatic and soil conditions. Consequently, nearly all the wheat flour used for snacks and other products are imported [2]. Composite flour technology is important because of the advantage of reducing the huge amount of money spent on wheat flour importation, coupled with the prospects of the utilization of underutilized crops [2,5].…”

“…Hence, wheat consuming countries located in tropical regions, which mostly are developing nations, rely on countries located in temperate regions for wheat importation [8]. The dependence on the use of wheat flour is a major constraint in biscuit production [2,9]. Watermelon (Citrillus lanatus), is a typical fruit from the Crucurbitaceae.…”
