摘要

本文研究了干燥方式和喷雾干燥入口温度对红花分离蛋白的颜色、表面形态、疏水性、粉末特性和功能特性的影响。采用碱性提取和等电沉淀法提取红花蛋白,然后在140、150、160、170和180℃的进风温度下进行冷冻干燥和喷雾干燥。与喷雾干燥样品相比,冻干红花分离蛋白的黏结性较低(1.18),流动性较好(15.12%),容重较高(0.31 g/cm3),抽头容重较低(0.37 g/cm3)。此外,其润湿时间(9.00 s)也较短。另一方面,与冻干样品相比,喷雾干燥样品颜色更浅,起泡量(30.00 ~ 38.75%)和稳定性(87.50 ~ 89.17%)更高,乳化活性(51.25 ~ 54.50%)和稳定性(85.76 ~ 87.51%)更高。此外,发现红花蛋白在140℃下喷雾干燥的起泡能力和乳液活性高于其他喷雾干燥样品。总的来说,冷冻干燥的红花蛋白具有较好的粉末特性,而喷雾干燥的红花蛋白具有较好的功能特性。结果表明,干燥方式和喷雾干燥入口温度的选择对红花蛋白的粉末特性和功能特性至关重要。

Physicochemical and functional properties of safflower protein isolate: Effect of drying methods and spray drying temperatures

In this study, the effects of the drying method and spray drying inlet air temperature on the color, surface morphology, hydrophobicity, powder and functional properties of safflower protein isolate were investigated. Safflower protein was extracted using the alkaline extraction and isoelectric precipitation method and then dried using freeze-drying and spray-drying at 140, 150, 160, 170, and 180 °C inlet air temperatures. When compared to the spray-dried samples, freeze-dried safflower protein isolate had lower cohesiveness (1.18) and better flowability (15.12%) with higher bulk density (0.31 g/cm3) and lower tapped bulk density (0.37 g/cm3). Additionally, its wetting time (9.00 s) was also found to be lower. On the other hand, spray-dried samples exhibited lighter color, higher foaming capacity (30.00–38.75%) and stability (87.50–89.17%), and emulsion activity (51.25–54.50%) and stability (85.76–87.51%) than the freeze-dried sample. Moreover, it was found that the foaming capacity and emulsion activity of safflower protein spray-dried at 140 °C were higher than those of other spray-dried samples. Overall, freeze-dried safflower protein showed better powder properties, while spray-dried samples had better functional properties. Consequently, it was shown that the choice of drying method and spray drying inlet air temperature were critical for the powder and functional properties of safflower protein.
