【摘要】：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 k Pa,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。
[Abstract]:Objective to study the preparation of porcine Achilles tendon sponge and its adsorption effect on ethanol in order to make better use of pig Achilles tendon resource, increase its added value and broaden the application of collagen in packaging. Methods the effects of collagen concentration, glycerol content and pouring thickness on the mechanical properties of pig Achilles tendon were investigated by single factor experiment. The effects of porosity and time of sponge on the adsorption of ethanol were investigated. Results when the mass fraction of collagen was 1%, the mass fraction of glycerol was 0.6 mm, and the thickness of pouring was 5 mm, The tensile strength and elongation at break of the prepared sponge are 210.91 kPA and 6.98 respectively. Under this condition, the porosity of the sponge is 91.19 ~ 30 d, the adsorption capacity of ethanol is 416.32 mg / g, and the adsorption capacity is positively correlated with the porosity of the sponge. Conclusion the collagen of pig Achilles tendon prepared by this process has higher tensile strength than that of other animal collagen sponges and can adsorb ethanol.
