    摘要:

    为了缩减胶原蛋白肠衣膜的制备工序,提高食品行业包装材料的质量,考察了戊二醛的添加顺序对胶原蛋白肠衣膜品质的影响。分别通过制胶时、成胶后以及成膜后3种添加方式,以抗拉强度、断裂延伸率、热收缩率、溶胀率、色泽及变性温度等为指标进行了研究。结果表明:在任一添加方式下,戊二醛都可促进胶原蛋白肠衣膜机械性能和表面疏水性的提高,导致溶胀率和热收缩率的下降;其中,通过FTIR和DSC分析表明,采用成膜后浸入戊二醛方式交联获得的肠衣膜交联效率最高,热稳定性最高,且对肠衣膜性能的提升最为显著;进一步,随着戊二醛添加量的提高,肠衣膜的色泽逐渐变黄,而当添加量超过100 mg/L时,戊二醛交联对肠衣膜品质并无进一步显著提升作用。

    Abstract:

    In order to reduce the production process of collagen casing film, and to improve the quality of packaging materials in food industry, the effect of glutaraldehyde addition sequence on the quality of collagen casing film was investigated. The tensile strength, elongation at break, thermal shrinkage, swelling rate, color and denaturation temperature were studied through three addition treatments, i.e., during the process of collagen paste making, after paste making, and after film forming, respectively. Results showed that glutaraldehyde could improve the mechanical properties and surface hydrophobicity, and decrease the swelling rate and thermal shrinkage rate of collagen casing films under any treatments. The results of FTIR and DSC showed that the films crosslinked with glutaraldehyde after film formation had the highest crosslinking efficiency and thermal stability, and the most significant improvement in film properties. Furthermore, with the increase of glutaraldehyde content, the color of casing film gradually changed yellow. However, when the content of glutaraldehyde was over 100 mg/L, there was no further significant improvements on the quality of casing films by the crosslinking of glutaraldehyde.
