Texturization of deoiled cake of sunflower, soybean and flaxseed into food grade meal and its utilization in preparation of cookies

Abstract

Purpose

The purpose of the present study was to plan with the objectives to optimize and find out the best level of texturized protein from sunflower, soybean and flaxseed on the basis of quality and overall acceptability of the cookies.

Design/methodology/approach

Defatted meal from sunflower, soybean and flaxseed was texturized using extruder. Texturized defatted meal of sunflower, soybean and flaxseed was blended at 10, 20, 30 and 40 per cent levels with wheat flour for making cookies using standard procedure.

Findings

Functional properties such as water absorption index, foaming capacity and protein digestibility were increased, while water solubility index and fat absorption capacity decreased with increased levels of texturized defatted meal in wheat flour. Spread ratio, sensory, colour and overall acceptability of cookies were negatively affected when level of texturized flour increased as compared with the control. The force required for breaking cookies decreased with increased level of texturized defatted meal of sunflower, soybean and flaxseed incorporation. Cookies with 10 per cent texturized sunflower, soybean and flaxseed flour received the highest sensory scores. The result showed that texturized defatted meals serve as good substitute to wheat flour with increased protein content in cookies production and utilization.

Originality/value

The study demonstrated that deoiled cake, a byproduct obtained from sunflower, soybean and flaxseed oil industry, offers great potential for supplementation of proteins in food products.
