Increasing the content of roasted flaxseed flour in biscuits led to significant increases in protein, fat, and ash content, while reducing hardness and spread factor. Adding 40% RFSF notably increased fiber content and improved total phenolic content, antioxidant activity, and volatile profile in the biscuits. The study demonstrated that adding 25% RFSF could enhance the nutritional value of biscuits without affecting taste, offering a healthy alternative for consumers.
The study aimed at assessing effects of partial replacement (0-40%) of wheat flour with roasted flaxseed flour (RFSF) on the quality attributes of biscuits. Nutritional, antioxidative, volatile and sensory properties, as well as texture analysis and the contents of macroelements and microelement were studied. Increasing RFSF content in biscuits resulted in a significant increase (p < 0.05) in protein (from 8.35% to 10.77%), fat (from 15.19% to 28.34%) and ash (from 1.23% to 2.60%) while the hardness and spread factor of the biscuits decreased with the increased level of roasted flaxseed flour. Moreover, the addition of 40% RFSF registered a positive influence on the fibre content of the final baked biscuits, increasing its value about 6.7-fold than in the control sample. Total phenolic content, antioxidant activity and biscuits' aroma volatile profile increased their amounts with RFSF addition. The nutritional, textural and sensorial results of the present study demonstrated that 25% RFSF could be added in the biscuits manufacturing without affecting the biscuits aftertaste, offering promising healthy and nutritious alternative to consumers.
