Raw Banana Flour-Enriched Muffins for Hypertensive Patients

Overview

This study evaluated the effects of raw banana flour (RBF)-enriched muffins on hypertensive patients in Lahore, Pakistan. A total of 34 patients were divided into three groups: a control group and two intervention groups receiving muffins with 35% (C1) or 40% (C2) RBF for 10 weeks. Sensory evaluation showed high acceptability of the 35% RBF muffins, comparable to control muffins. Clinical outcomes indicated that both intervention groups experienced improvements in body weight, BMI, blood pressure, liver enzymes, and lipid profiles, with more pronounced benefits observed in the 40% RBF group. The findings suggest that RBF-enriched muffins, particularly at 40% substitution, can offer functional, nutritional, and clinical benefits for individuals with hypertension.

2\. Materials and Methods The study received ethical approval from the University of Lahore (REC-UOL/466/08/24). Informed consent was obtained from all participants, who were fully informed about the study's aims, methods, risks, and benefits, and were allowed to ask questions and withdraw at any time. 2.2. Materials Raw banana flour, whole wheat flour, brown sugar, baking powder, pink salt, coconut oil, vanilla essence, cinnamon powder, eggs, and plastic bags were procured from the local market of Lahore, Pakistan, and subsequently stored in the Food Science and Nutrition Lab at the University Institute of Diet and Nutritional Sciences (UIDNS), University of Lahore, Pakistan. Standard kits from Merck Specialities Pvt. Ltd. were employed to assess liver enzyme tests and lipid profiles. 2.3. Settings: This study took place at the Food Science and Nutrition Lab, UIDNS, University of Lahore, and Nutrition Department, Noor Hospital Lahore, Lahore, Pakistan. 2.4. Sensory Evaluation Muffins were tasted by 10 professionals. Randomly placed muffins have two-digit codes. Cookies with two-digit numbers were distributed randomly. The panelists used a 9-point hedonic scale (9 = highly liked; 1 = severely disliked) to rate color, appearance, flavor, texture, overall acceptability, and affordability (Wichchukit \& O'Mahony, 2015). During sensory evaluation, panelists cleaned their taste receptors with mineral water and expectorant cups (Handa et al., 2012). 2.5. Subjects In this pilot study, 48 patients signed up; however, 6 of them were not allowed to participate because they did not meet the requirements (Figure 1). We randomly put 42 patients into three groups. There were three groups of 42 patients, each with the same number of people. There were 14 people in each group. Four people were left out of the control group (C0) because of some personal issues. Two people were taken out of the intervention group (C1) because they had to travel, were constipated, or started using an alternative medicine. Two other people moved from the intervention group (C2) to start taking an alternative medicine. Figure 1 shows that 10 patients were in the control group, 12 were in the intervention group (C1), and 12 were in the other intervention group (C2). All of them finished the trial and were tested after 10 weeks, lipid profile and liver enzymes were assessed at the end of study. 2.6 2.9. Statistical analysis All sensory evaluation data were expressed as mean ± standard deviation (SD). One-way analysis of variance (ANOVA) was performed to determine significant differences among the control and raw banana flour-enriched muffin sample groups for each sensory attribute (Steel \& Torrie, 1981).
