| 目的 为了更好利用猪跟腱资源，提高其附加值及拓宽胶原在包装方面的应用，探讨猪跟腱胶原蛋白海绵的制备及该海绵对乙醇的吸附作用。方法 采用单因素实验考察猪跟腱胶原蛋白浓度、甘油含量、浇注厚度对力学性能的影响，并考察海绵孔隙率和时间对乙醇吸附性能的影响。结果 当胶原的质量分数为1%，甘油的质量分数为0.6%，浇注厚度为5 mm时，制备的海绵抗张强度为210.91 kPa，断裂伸长率为6.98%，此工艺条件下制备的海绵孔隙率为91.19%，30 d乙醇吸附量为416.32 mg/g，吸附量与海绵的孔隙率成正相关。结论 猪跟腱胶原蛋白在此工艺下制备的海绵比其他动物胶原蛋白海绵的抗张强度高，且对乙醇具有吸附作用。 |

| The work aims to make better use of the resource of pig’s tendons to improve the added value and widen the application of collagen in packaging, and study the preparation of collagen sponge from pig’s tendon and its adsorption performance for ethanol. Through the single factor experiment, the effects of concentration of collagen from pig’s tendons, glycerol content and casting thickness on the mechanical properties were studied. Then, the effects of sponge porosity and time on the adsorption performance for ethanol were studied. When the mass fractions of collagen and glycerol were respectively 1% and 0.6% and the casting thickness was 5 mm, the tensile strength of sponge prepared was 210.91 kPa and the elongation at break was 6.98%, the porosity of sponge prepared under such technological conditions was 91.19%, and the adsorption quantity for ethanol was 416.32 mg/g at 30 d. Besides, the adsorption quantity was positively correlated with the porosity of the sponge. The tensile strength of collagen sponge from pig’s tendon prepared under such technological conditions is higher than that of other animals, and the sponge has the adsorption effect on ethanol. |
