This study aimed to construct oleofilms containing a binary mixture of proteins (soy protein hydrolysate and gelatin) and lipids (olive oil, stearic acid, and lecithin) using various ultrasonic emulsification processes. Initially, oleogels (OG20, OG40, OG60, OG80, and OG100) were fabricated with different sonication powers (20 %-100 %), along with control (OG) without sonication. Macrostructure, FTIR, DSC, stability coefficient (57.27 %-79.52 %), oil-binding capacity (68.38 %-97.47 %), and particle size (1364-3532 nm) tests were performed on the oleogels. Oleofilms (OF, OF20, OF40, OF60, OF80, and OF100) were then formulated using the respective oleogels. Their visual, surface, and cross-sectional images were evaluated. The thickness (0.18-0.25 mm) and water content (7.32 %-11.73 %) of oleofilms were investigated. Alterations in color and opacity (3.50-5.49) of the oleofilms were apparent. OF80 exhibited lower water (0.44 g.mm/m.h.kPa)/oxygen permeability (peroxide value: 2.31-14.30 meq O/kg), along with improved mechanical properties (tensile strength: 3.25 MPa; elongation at break: 128.23 %). OF80-coated pineapples demonstrated the highest resistance to spoilage.
本研究旨在通过各种超声乳化工艺构建含有蛋白质（大豆蛋白水解物和明胶）和脂质（橄榄油、硬脂酸和卵磷脂）二元混合物的油膜。最初，使用不同的超声功率（20% - 100%）制备油凝胶（OG20、OG40、OG60、OG80和OG100），并设置未进行超声处理的对照组（OG）。对油凝胶进行了宏观结构、傅里叶变换红外光谱（FTIR）、差示扫描量热法（DSC）、稳定性系数（57.27% - 79.52%）、持油能力（68.38% - 97.47%）和粒径（1364 - 3532纳米）测试。然后使用相应的油凝胶配制油膜（OF、OF20、OF40、OF60、OF80和OF100）。对它们的外观、表面和横截面图像进行了评估。研究了油膜的厚度（0.18 - 0.25毫米）和含水量（7.32% - 11.73%）。油膜的颜色和不透明度（3.50 - 5.49）有明显变化。OF80表现出较低的透水性（0.44克·毫米/米·小时·千帕）/氧气透过率（过氧化值：2.31 - 14.30毫克当量氧/千克），同时机械性能有所改善（拉伸强度：3.25兆帕；断裂伸长率：128.23%）。用OF80包被的菠萝表现出最高的抗腐败能力。
