摘要:

以鲜猪血为原料,研究在猪血凝胶制备过程中转谷氨酰胺酶(TG)添加量、NaCl添加量及血水比对猪血凝胶蒸煮损失率、质构特性、色泽的影响。结果表明:添加TG能显著提高猪血凝胶品质,且TG添加量在0.2%左右时为最佳,当TG添加量大于0.2%时,血凝胶品质显著下降,蒸煮损失明显增加且伴有严重的起泡现象。NaCl浓度0.3mol/L、血水比控制在1:2.4(V/V)时所形成的猪血凝胶质构特性、保水性、色泽较好。

关键词: 猪血凝胶, 转谷氨酰胺酶, 蒸煮损失率, 质构, 色泽

Abstract:

This study reports on the use of transgluminase (TG) for enzymatic preparation of heat-induced porcine blood gels
from fresh porcine blood. Various experimental conditions, such as TG dosage, the amount of added NaCl and blood-to-water
ratio were investigated for their influence on cooking loss, textural properties and color of heat-induced porcine blood gel. Results
indicated that the textural properties of heat-induced porcine blood gels exhibited a significant enhancement when added with 0.2%
of TG. The heat-induced gels revealed significantly deteriorated quality, an evident increase in cooking loss and a severe foaming
phenomenon when more TG was added. The heat-induced gels formed at NaCl concentration of 0.3 mol/L and a blood-to-water
ratio of 1:2.4 (V/V) had good textural properties, water-holding capacity and color.

Key words: pork blood gel, transglutaminase (TG), cooking loss, texture, color parameters
