Utilization of Banana Peel Flour in Biscuit Making as Wheat Flour Substitute

The production of biscuits utilizing ripe banana peel flour (BPF) as a wheat flour (WF) alternative is presented in this study. Locally available Sabri banana peel was dried into a cabinet dryer at 65⁰C for 8 hours. The dried peel then turned into powder and sieved. The flours used in the preparation of the biscuits were analyzed for proximate composition. BPF contained a higher amount of fat compared to WF. Five samples of biscuits S1, S2, S3, S4, and S5 substituting WF with 0, 5, 10, 20, and 30% BPF in the standard biscuits were prepared S1 denoted the control sample adding no BPF. The proximate composition and sensory quality of the produced biscuits were tested. All of the biscuit samples had greater weights than the control biscuit. In comparison to the control biscuit, BPF enriched biscuits had reduced diameter. Biscuits made with 10% BPF had a greater spread ratio than those made with other ingredients. The moisture, protein, fat, and total sugar content of biscuit samples were found in the range of 4.05-5.32%, 6.60-9.00%, 10.00-10.32%, and 17.00-25.00%, respectively. A sharp decrease in protein content was observed with the increase of BPF in the biscuits. A slight increase of fat was observed in the BPF substituted biscuits. The ash content in the control sample was 1.5%, and that in the banana peel substituted samples ranged from 1.80% to 2.0%. BPF substitution showed a downward trend in terms of color, flavor, texture, and general acceptability. The panelists rated sample S1 as having the highest overall acceptability. Among the BPF-containing biscuits, sample S2 had the best overall acceptance, followed by samples S3, S4, and S5. In terms of general acceptability, however, there are no notable variations between samples S2 and S3. According to sensory analysis, quality BPF biscuits may be prepared by replacing up to 10% of the WF with BPF.

Chickpea and Chestnut Flours as Non-Gluten Alternatives in Cookies

This study proposes the use of a mix composed of chickpea flour and chestnut flour in cookies, aiming to improve their acceptability. Cookie properties and nutritional value were also analysed. The gluten-free cookies were made by using different mixes of chickpea and chestnut flours (0:100, 25:75, 50:50, 75:25, 100:0). Dough rheology and cookie dimensions, texture, external colour and acceptability were evaluated. The presence of the chestnut flour increased the values of G’ and G”, but reduced the loss factor (tan δ) when compared with the doughs made with chickpea flour. Chestnut flour also decreased the diameter and the spread ratio of the cookies, while increasing the hardness and darkening of the cookies. Furthermore, adding chestnut to the flour mixture increased the nutritional quality of the cookies by adding unsaturated fatty acids and fibre. The use of reduced percentages of chestnut flour (25%) resulted in masking the off-flavour of the chickpea flour, which improved the cookie’s acceptability without significantly changing the dough rheology, cookie dimensions, hardness, or lightness.
