摘要： In this study, the study on physicochemical, rheological properties and water-holding capacity of gelatin of chicken lungs was investigated to replace bovine and porcine gelatin. The extraction rates of chicken, bovine and porcine lung gelatin by ultrasound assisted alkaline protease were 52.12 %, 69.06 % and 70 %, respectively. Three lung gelatins had similar molecular weight distribution in SDS-PAGE with low content of high molecular weight subunits. The amino acid content of bovine lung gelatin (18.03 %) was higher than in chicken (16.62 %) and porcine lung (15.30 %). The highest intensity of 2 theta = 7.5 degrees diffraction peak in bovine lung gelatin was observed, which indicated that the triple helix content of bovine lung gelatin was higher than that of chicken and porcine lung gelatin. The lowest apparent viscosity of chicken lung gelatin was 0.253 mPa & sdot;s, but the highest water holding capacity of chicken lung gelatin was 331.72 %. Therefore, chicken lung gelatin can be used as a substitute for bovine and porcine gelatin in some functional properties.
