In recent years, there has been growing interest in the production of ingredients rich in dietary fiber and antioxidants, such as green banana flours. This study evaluated the effect of consumption of mixed green banana pulp (PF) and peel (PeF) flours on the body weight gain, adiposity, lipid profile, and intestinal morphology of rats. Male young rats were divided into four groups (n = 8) that received a standard diet (SD), or one of the following three test diets: M1 (SD + 90% PF/10% PeF), M2 (SD + 80% PF/20% PeF), or P (SD + 100% PF) for 28 days. Rats from M1, M2, and P groups showed reduced body weight gain and adiposity and had lower contents of total cholesterol, LDL-c, VLDL-c, and triglycerides. Animals from M1 and M2 groups had an increase in cecum weight, fecal moisture, acetic acid concentration, and crypt depth and reduced fecal pH. Moreover, consumption of the M1, M2, and P diets increased the expression of proteins involved in intestinal functionality. Significant negative correlations were observed between consumption of resistant starch and soluble dietary fiber, from the flours, and weight gain (r = -0.538 and r = -0.538, respectively), body adiposity (r = -0.780 and r = -0.767, respectively), total cholesterol (r = -0.789 and r = -0.800, respectively), and triglycerides (r = -0.790 and r = -0.786, respectively). Mixed green banana pulp and peel flour proved to be a viable alternative as a food ingredient that can promote weight loss, improve lipid profile and intestinal morphology, and minimize post-harvest losses.
近年来，人们对生产富含膳食纤维和抗氧化剂的成分（如青香蕉粉）的兴趣日益浓厚。本研究评估了食用混合青香蕉果肉（PF）和果皮（PeF）粉对大鼠体重增加、肥胖、血脂谱和肠道形态的影响。雄性幼鼠被分为四组（n = 8），分别接受标准饮食（SD），或以下三种试验饮食之一：M1（SD + 90% PF/10% PeF）、M2（SD + 80% PF/20% PeF）或P（SD + 100% PF），持续28天。M1、M2和P组的大鼠体重增加和肥胖程度降低，总胆固醇、低密度脂蛋白胆固醇、极低密度脂蛋白胆固醇和甘油三酯含量较低。M1和M2组的动物盲肠重量增加、粪便水分增加、乙酸浓度增加、隐窝深度增加，粪便pH值降低。此外，食用M1、M2和P饮食可增加参与肠道功能的蛋白质表达。观察到面粉中的抗性淀粉和可溶性膳食纤维的摄入量与体重增加（分别为r = -0.538和r = -0.538）、身体肥胖（分别为r = -0.780和r = -0.767）、总胆固醇（分别为r = -0.789和r = -0.800）以及甘油三酯（分别为r = -0.790和r = -0.786）之间存在显著负相关。混合青香蕉果肉和果皮粉被证明是一种可行的食品成分替代品，它可以促进体重减轻、改善血脂谱和肠道形态，并最大限度地减少收获后的损失。
