明胶基环保油墨的制备和食品应用研究进展

Preparation and food application of environmental-friendly inks based on gelatin

随着消费者对健康、环保的关注,针对食品应用的印刷领域,绿色、环保、无毒油墨的研究逐渐兴起。明胶具有可食性、可降解性、黏性、成膜性等优良理化性质,在食品、农业、工业等领域应用广泛,可用于制备明胶基油墨。该文阐述了明胶与多种颜色色料(红、黄、蓝、白、黑等色料)复合并制备油墨的现状,概述了明胶基油墨在食品装饰和食品电子产品中的应用,并对明胶在绿色环保油墨中的发展方向做了展望,希望能够对明胶基油墨在食品领域的应用提供相应的理论依据。

With consumers′attention to health and environmental protection,especially for inks applying into food fields,the study of green,environmentally-friendly,non-toxic inks is emerging.Gelatin has good physical and chemical properties including edibility,degradability,viscous property and film-forming property,and it is widely used in various fields including food,agriculture,industry,which can be used to prepare gelatin-based inks.This paper discussed the progress of gelatin-pigment(red,yellow,blue,white,black,etc.)composite,summarized the application of gelatin based ink in food decoration and electronic products(based on food),and pointed out the development direction of gelatin in environmentally-friendly ink,hoping to provide the corresponding theoretical basis for gelatin based ink in food.
