Saturated animal fat was replaced in pork pâté with pre-emulsified canola in a 3% sodium caseinate/0.5% xanthan gum solution in order to obtain a stable oily phase. Fat was replaced with different proportions of emulsified canola oil. The inclusion of emulsified oil in pâté enhanced cocking yield and moisture but increased fluids release. Nonetheless, total fat content remained practically constant, meaning no detrimental effect on caloric content. Replacing 50% of lard with emulsified oil did not affect color of the samples. Texture was improved since emulsified oil addition resulted in softer and more spreadable pâté. Samples with 50% of emulsified oil were more stable to lipid oxidation at 8 days of storage, with lower thiobarbituric acid-reactive substances and volatile compounds resulting from oxidation reactions. Emulsified canola can be employed to replace fat until 50% in pâté or liver sausage with good functional properties, improving texture and reducing lipids rancidity.
为了获得稳定的油相,在 3%的酪蛋白酸钠/0.5%黄原胶溶液中用预乳化的菜籽油替代猪肉冻糕中的饱和动物脂肪。用不同比例的乳化菜籽油替代脂肪。在冻糕中加入乳化油可以提高蒸煮产率和水分,但会增加液体的释放。尽管如此,总脂肪含量实际上保持不变,这意味着对卡路里含量没有不利影响。用乳化油替代 50%的猪油不会影响样品的颜色。由于乳化油的添加使冻糕更柔软、更易于涂抹,因此质地得到了改善。在储存 8 天的情况下,含有 50%乳化油的样品对脂质氧化的稳定性更高,氧化反应产生的硫代巴比妥酸反应物质和挥发性化合物更少。在猪肉冻糕或肝肠中,乳化菜籽油可以替代高达 50%的脂肪,具有良好的功能特性,可改善质地并降低脂肪的酸败。
