Pequi (Caryocar brasiliense Camb.) and buriti (Mauritia flexuosa L.) are fruits with potential for extraction of edible vegetable oil with high carotenoid content. The aim of this study was incorporated these oils (5 % or 10 %) into cassava starch-based films and verify their photoprotective effect on pigments and maintenance of lipid oxidative stability. Vegetable oils showed a similar profile for carotenoids, with β-carotene being the major pigment (74-77 %). The hydrophobic character and presence of carotenoids in the oils, led to reduced hydrophilicity of the films, better barrier to UV-visible light transmission and to the plasticizing effect. The active films showed rapid biodegradability in soil (60-70 % after 15 days), in addition to a protective effect against photodegradation of the β-carotene solution by increasing the half-life (t). When applied as packaging for storing corn oil under accelerated oxidation conditions, there was less formation of degradation compounds, which demonstrates potential application as food packaging.
披吉果（Caryocar brasiliense Camb.）和布里蒂果（Mauritia flexuosa L.）是具有提取高类胡萝卜素含量可食用植物油潜力的水果。本研究的目的是将这些油（5%或10%）掺入木薯淀粉基薄膜中，并验证它们对色素的光保护作用以及对脂质氧化稳定性的维持作用。植物油类胡萝卜素谱相似，β-胡萝卜素是主要色素（74 - 77%）。油类的疏水特性和类胡萝卜素的存在导致薄膜亲水性降低、对紫外 - 可见光透射的阻隔性更好以及具有增塑作用。活性薄膜在土壤中显示出快速生物降解性（15天后为60 - 70%），此外还通过延长半衰期（t）对β-胡萝卜素溶液的光降解具有保护作用。当用作在加速氧化条件下储存玉米油的包装时，降解化合物的形成较少，这表明其作为食品包装具有潜在应用价值。
