Abstract

This study investigated the ultrasound-assisted extraction (UAE) techniques used to enhance the polyphenols and antioxidants of mango peel extract (MPE). Additionally, it explored the bacteriostatic activity of MPE against various microorganisms. The UAE method was optimized using response surface methodology (RSM) at different times, temperatures, and ratios, with optimal conditions found to be 35 minutes, 45 °C, and a 1:35 ratio. The optimized yield results for total polyphenol content (TPC) were 17.33 ± 1.57 mg GAE/g, total flavonoid content (TFC) was 12.14 ± 0.29 mg QE/g, and radical scavenging activity (RSA) was 72.11 ± 2.19%. These response models were extremely significant with p-values less than 0.05. MPE showed selective effectiveness against Bacillus cereus, Geobacillus stearothermophilus, and Escherichia coli (E. coli). The results highlight the potential of mango peel as a sustainable source of bioactive compounds, contributing to waste reduction in the food industry and the development of natural antimicrobial agents. This study contributes to further research on the application of MPE in processed foods.

最大限度地提高多酚产量：芒果皮的超声波辅助提取和抗菌潜力。

本研究调查了用于提高芒果皮提取物（MPE）中多酚和抗氧化剂含量的超声辅助萃取（UAE）技术。此外，研究还探讨了 MPE 对各种微生物的抑菌活性。采用响应面法（RSM）对不同时间、温度和比例下的 UAE 方法进行了优化，发现最佳条件为 35 分钟、45 °C、1:35 比例。总多酚含量（TPC）为 17.33 ± 1.57 mg GAE/g，总黄酮含量（TFC）为 12.14 ± 0.29 mg QE/g，自由基清除活性（RSA）为 72.11 ± 2.19%。这些反应模型非常显著，P 值小于 0.05。MPE 对蜡样芽孢杆菌、嗜热地衣芽孢杆菌和大肠杆菌具有选择性效力。研究结果凸显了芒果皮作为生物活性化合物可持续来源的潜力，有助于减少食品工业中的浪费和天然抗菌剂的开发。这项研究有助于进一步研究 MPE 在加工食品中的应用。
