This study aimed to characterize and evaluate the in vitro bioactive properties of green banana pulp (GBPF), peel (GBPeF), and mixed pulp/peel flours M1 (90/10) and M2 (80/20). Lipid concentration was higher in GBPeF (7.53%), as were the levels of free and bound phenolics (577 and 653.1 mg GAE/100 g, respectively), whereas the resistant starch content was higher in GBPF (44.11%). Incorporating up to 20% GBPeF into the mixed flour had a minor effect on the starch pasting properties of GBPF. GBPeF featured rutin and trans-ferulic acid as the predominant free and bound phenolic compounds, respectively. GBPF presented different major free phenolics, though it had similar bound phenolics to GBPeF. Both M1 and M2 demonstrated a reduction in intracellular reactive oxygen species (ROS) generation. Consequently, this study validates the potential of green banana mixed flour, containing up to 20% GBPeF, for developing healthy foods and reducing post-harvest losses.
本研究旨在对绿香蕉果肉(GBPF)、果皮(GBPeF),以及混合果肉/果皮粉 M1(90/10)和 M2(80/20)进行特性描述和体外生物活性评估。GBPeF 的脂质浓度(7.53%)较高,游离和结合酚类(分别为 577 和 653.1mgGAE/100g)的水平也较高,而 GBPF 的抗性淀粉含量较高(44.11%)。将高达 20%的 GBPeF 掺入混合粉中,对 GBPF 的淀粉糊化特性影响较小。GBPeF 的主要游离酚类化合物分别为芦丁和反式阿魏酸,而主要结合酚类化合物则为绿原酸。GBPF 虽与 GBPeF 具有相似的结合酚类,但表现出不同的主要游离酚类。M1 和 M2 均能减少细胞内活性氧(ROS)的产生。因此,本研究验证了含有高达 20%GBPeF 的绿香蕉混合粉用于开发健康食品和减少采后损失的潜力。
