Abstract

Abstract Biodegradable films based on mung bean protein (1, 3 and 5%) incorporated with cumin essential oil (EO) (0, 0.25 and 0.5 ml/g protein) were developed. Adding cumin oil and increasing the protein content enhanced the thickness, tensile strength and yellowness. Films incorporated with EO exhibited less water vapor permeability and water solubility, as compared to the control films. A higher antioxidant activity was also obtained by increasing the EO and protein ratios. Films with higher levels of protein displayed lower thermal stability with a lower degradation temperature, as suggested by thermo-gravimetric analyses. In addition, the incorporation of EO reduced thermal stability, as confirmed by the higher weight loss and lower degradation temperature. Furthermore, mung bean protein films containing 0.5 ml cumin oil/g protein had suitable physical characteristics, antioxidant activities, water barrier properties and thermal stability; thus, they can be used as appropriate biodegradable packaging materials for food preservation.

掺入孜然精油的绿豆蛋白膜的研制与表征
摘要研制了以绿豆蛋白(1%、3%和5%)和孜然精油(0、0.25和0.5ml/g蛋白)为主要原料的生物降解膜。添加孜然油和增加蛋白质含量可以提高厚度、抗拉强度和黄度。与对照膜相比,掺入EO的膜表现出较小的水蒸气渗透性和水溶性。通过增加EO和蛋白质的比例也获得了更高的抗氧化活性。热重分析表明,具有较高蛋白质水平的膜在较低的降解温度下表现出较低的热稳定性。此外,EO的加入降低了热稳定性,更高的重量损失和更低的降解温度证实了这一点。此外,含有0.5ml孜然油/g蛋白质的绿豆蛋白质膜具有合适的物理特性、抗氧化活性、防水性能和热稳定性;因此,它们可以用作适当的可生物降解的食品保鲜包装材料。
