Physicochemical and Nutritional Properties of Baby-Led Cookies Produced from Rice, Banana and Cashew-nut Flour Blends

Aim: Cookies from rice, banana and cashew-nut flour blends were prepared as alternative to gluten-free baby-led food for children. Place and Duration of Study: The study was carried out in the Chemistry Laboratory, Department of Science Laboratory Technology, University of Medical Sciences, Ondo, Nigeria and Food Processing Laboratory, Department of Food Technology, Auchi Polytechnic, Auchi, Nigeria between August, 2022 and January, 2023. Methodology: Baby-led weaning cookies were formulated from flour blends as 100% raw rice (RRC), 50% rice and 50% wheat (RWC) and 40% rice, 20% cashew and 40% unripe banana (RCB) and their physical properties, sensory attributes, proximate properties, mineral compositions, vitamin profiles and anti-nutrients were determined and compared with 100% commercial cookie (CMC) with the view to substituting wheat flour with suitable flour blends with enhanced nutritional quality. Results: The peak diameter (10.40±0.20 mm), thickness (6.37±0.06 mm) and weight (17.65±0.04 g) were obtained in RCB. Spread ratio was highest (2.66±0.11) and lowest (1.42±0.01) in CMC and RWC respectively while spread factor decreased from 100% in CMC to 77.19% (RRC), 53.46% (RWC) and 62.47% (RWC). The grittiness, texture, aroma, taste and general acceptability of RCB were significantly similar to those of CMC (P < 0.05). Na, K, Mg and Zn contents increased in RCB. Proximate compositions (%) of the cookies formulated varied significantly from CMC. Peak crude protein (14.49±0.59), crude fibre (4.03±0.02) and fat (32.22±0.00) in RCB, ash (3.28±0.02) and carbohydrate by difference (58.15±0.13) in CMC and moisture (18.19±0.11) in RRC. The peak values of fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (B1, B2, B3, B6, B9, B12, C) were most abundant in RCB. The proportions (mg/g) of phytate, oxalate, tannins and phenols in the cookies formulated were comparatively lower than the lethal dose, implying that the cookies would be safe for consumption. Conclusion: RCB cookie had excellent nutritional quality, which, as a novel baby-led weaning cookie, could serve as a suitable alternative to commercial cookies.
