| 中文摘要: |
| 目的 制备一种纯天然的、具有抑菌性的可食用淀粉膜。方法 以玉米淀粉为原料，通过添加适量的姜渣、甘油、羧甲基纤维素钠，采用流延法制备姜渣-玉米淀粉膜。结果 当淀粉的质量分数为3%，甘油的质量分数为1%，姜渣的质量分数为0.4%时，膜的透光性、透油性、水蒸气透过性、溶解度、溶胀度等各项指标的综合测定结果较好。生姜中含有姜辣素、姜油等活性成分，添加姜渣可作为天然的抑菌剂，微生物试验结果证实，姜渣-玉米淀粉膜对霉菌和酵母菌具有一定抑菌作用，且抑菌效果与姜渣的含量成正比关系。结论 所制备姜渣-玉米淀粉的结构紧密、光滑平整，并具有一定的抑菌性。 |
| 英文摘要: |
| The work aims to prepare a natural edible starch-based film with antimicrobial activity. The ginger residue-corn starch film was prepared by the casting method with the corn starch as the raw material, added with an appropriate amount of ginger residue, glycerol and sodium carboxymethyl cellulose (CMC). When the mass fraction of starch was 3%, the mass fraction of glycerol was 1%, and the mass fraction of ginger residue was 0.4%, the comprehensive measurement results of the film's indexes were better, including transparency, oil permeability, water vapor permeability, solubility and swelling. The added ginger residue could be used as the natural antibacterial agent as the fresh ginger contained gingerol, ginger oil and other active ingredients. The results of microorganism experiment confirmed that ginger residue-corn starch film had certain bacteriostatic effect on aspergillus and yeast. Furthermore, the bacteriostatic effect was proportional to the content of ginger residue. Featured by a compact structure and smoothness, the prepared ginger residue-corn starch film has certain antimicrobial activity. |
