The surface and nutraceutical properties have been poorly studied on edible films. The aim of this study was to investigate the surface properties and potential health effects in terms of in vitro digestibility and anti-inflammatory activity. The materials were developed from native plantain starch and pre-gelatinized plantain flour with and without added blackberry pulp using casting methodology. Thermogravimetric analysis, contact angle, scanning electron microscopy, atomic force microscopy, resistant starch, in vitro digestibility, cell viability, reactive oxygen species, anti-inflammatory activity and sensory evaluation were the tests carried out in this study. Films containing blackberry pulp had more compact and smooth morphologies, which were related to the lower in vitro digestibility rate and the higher resistant starch content. In addition, these materials had higher anti-inflammatory activity, higher cell viability, and better acceptance by the panelists, thus suggesting potential health effects of consumers with special feeding regimes such as obese, diabetics and celiacs.
关于可食用薄膜的表面和营养特性的研究还很少。本研究的目的是研究表面特性和潜在的健康影响，包括体外消化率和抗炎活性。这些材料是通过浇铸法由天然芭蕉淀粉和预糊化芭蕉粉与和/或添加黑莓浆制成的。本研究进行了热重分析、接触角、扫描电子显微镜、原子力显微镜、抗性淀粉、体外消化率、细胞活力、活性氧、抗炎活性和感官评价。含有黑莓浆的薄膜具有更致密和更光滑的形态，这与较低的体外消化率和较高的抗性淀粉含量有关。此外，这些材料具有更高的抗炎活性、更高的细胞活力以及更好的小组评价，这表明它们对特殊饮食人群（如肥胖、糖尿病和乳糜泻患者）具有潜在的健康影响。
