Transglutaminases (TG) are enzymes that improve the functional properties of proteins in meat products, contribute to the strong cohesion of meat without the further need for the addition of sodium chloride or phosphates, and have a positive effect on the texture of the meat product. This study aimed to investigate the physicochemical and sensory attributes of intact and restructured chicken meat supplemented with different TG proportions. The study was conducted on chicken breast meat samples ( = 40) originating from the line Ross 308. The intact samples were separated from the muscle, whereas the rest of the breast meat was ground, divided into equal parts, and supplemented with TG (0.2%; 0.4%; 0.6%; 0.8%; 1%). The intact meat had the highest cooking loss (19.84) when compared to 0.2% (15.51), 0.4% (15.04), 0.6% (14.95), 0.8% (14.95), and 1% (15.79) TG-supplemented meat. The intact meat had greater shear force (16.90) than 0.2% (5.16), 0.4% (5.39), 0.6% (5.16), 0.8% (5.98), and 1% (6.92) TG supplemented meat. There was no difference between intact meat and TG-supplemented meat in color, taste, odor, texture, and overall acceptability ( > 0.05). Therefore, TG supplementation can be used in improving yield and texture of minced chicken meat.
转谷氨酰胺酶(TG)是一种可改善肉制品中蛋白质功能特性的酶,有助于肉类紧密结合,无需额外添加氯化钠或磷酸盐,并且对肉制品的质地有积极影响。本研究旨在探究添加不同比例TG的完整鸡肉和重组鸡肉的理化特性和感官属性。研究使用了来自罗斯308品系的鸡胸肉样本( = 40)。完整样本取自 肌肉,其余鸡胸肉则进行研磨,分成等量部分,并添加TG(0.2%;0.4%;0.6%;0.8%;1%)。与添加0.2%(15.51)、0.4%(15.04)、0.6%(14.95)、0.8%(14.95)和1%(15.79)TG的肉相比,完整肉的煮损失率最高(19.84)。完整肉的剪切力(16.90)大于添加0.2%(5.16)、0.4%(5.39)、0.6%(5.16)、0.8%(5.98)和1%(6.92)TG的肉。完整肉与添加TG的肉在颜色、味道、气味、质地和总体可接受性方面无差异( > 0.05)。因此,添加TG可用于提高碎鸡肉的产量和质地。
