This study assessed the nutritional profile of camellia oil through its fatty acid composition, highlighting its high oleic acid content (81.4%), followed by linoleic (7.99%) and palmitic acids (7.74%), demonstrating its excellence as an edible oil source. The impact of beeswax (BW) and glycerol monolaurate (GML) on camellia oil oleogels was investigated, revealing that increasing BW or GML concentrations enhanced hardness and springiness, with 10% BW oleogel exhibiting the highest hardness and springiness. FTIR results suggested that the structure of the oleogels was formed by interactions between molecules without altering the chemical composition. In biscuits, 10% BW oleogel provided superior crispness, expansion ratio, texture, and taste, whereas GML imparted a distinct odor. In sausages, no significant differences were observed in color, water retention, and pH between the control and replacement groups; however, the BW group scored higher than the GML group in the sensory evaluation. The findings suggest that the BW oleogel is an effective fat substitute in biscuits and sausages, promoting the application of camellia oil in food products.
本研究通过脂肪酸组成评估了茶油的营养概况,突出其高油酸含量(81.4%),其次是亚油酸(7.99%)和棕榈酸(7.74%),证明其是一种优秀的食用油来源。研究了蜂蜡(BW)和甘油单月桂酸酯(GML)对茶油油凝胶的影响,结果表明,增加 BW 或 GML 浓度可以提高硬度和弹性,其中 10% BW 油凝胶的硬度和弹性最高。傅里叶变换红外光谱(FTIR)结果表明,油凝胶的结构是通过分子间相互作用形成的,而不会改变其化学成分。在饼干中,10% BW 油凝胶赋予饼干更好的酥脆度、膨胀比、质地和口感,而 GML 则赋予其独特的气味。在香肠中,对照组和替代组之间在颜色、水分保持和 pH 值方面没有显著差异;然而,在感官评价中,BW 组的得分高于 GML 组。研究结果表明,BW 油凝胶是饼干和香肠中有效的脂肪替代品,促进了茶油在食品中的应用。
