In this paper, Spirulina platensis protein-based emulsion gels were investigated as fat substitutes in meat analogs and compared with conventional fat sources like palm oil, oleogel, and soybean oil. Evaluating parameters such as cooking loss, shrinkage, texture, appearance, and moisture distribution across various cooking methods. Emulsion gels imparted superior juiciness to meat analogs whereas palm oil and oleogel led to drier meat textures. Besides they also resulted in comparable cooking loss and shrinkage to traditional fats, indicating preferred fat options for incorporation of emulsion gels. The novel emulsion gel-filled meat analogs exhibited robust tolerance across three distinct cooking methods, boiling, steaming, and deep-frying. Steamed meat analogs exhibited brighter MRI signals, while fried counterparts displayed peripheral hollowing, attributed to steam's energy transfer and humidity-induced water migration, respectively. Overall, the study underscores the efficacy of these fat analogs in meat analogs, offering insights into their potential as viable alternatives in food formulations.
本文研究了螺旋藻蛋白基乳液凝胶作为肉类模拟物中的脂肪替代品,并与传统脂肪来源(如棕榈油、油凝胶和大豆油)进行了比较。评估了各种烹饪方法下的烹饪损失、收缩、质地、外观和水分分布等参数。乳液凝胶赋予肉类模拟物更好的多汁性,而棕榈油和油凝胶则导致肉质更干燥。此外,它们的烹饪损失和收缩与传统脂肪相当,表明乳液凝胶是一种理想的脂肪替代物。新型乳液凝胶填充的肉类模拟物在三种不同的烹饪方法(煮沸、蒸煮和油炸)下具有较强的耐受性。蒸煮的肉类模拟物显示出更亮的 MRI 信号,而油炸的对应物则显示出外围空洞化,这分别归因于蒸汽的能量传递和湿度引起的水分迁移。总的来说,该研究强调了这些脂肪替代品在肉类模拟物中的功效,为它们在食品配方中的潜在可行性提供了新的见解。
