Developing high quality 3D printed foods

该项目将探索使用3D打印机以低成本打印定制食品，同时仍确保食品的高质量和安全食用。该项目将首先调查消毒策略时，由用户打印食品。将确定可用于打印机打印墨盒的食品级材料，并检查使用后对材料进行消毒的策略。该步骤将通过在消毒前后对印刷材料进行微生物检测进行验证。印刷材料的质地质量也将被检查。三种食物基质（基于脂质、基于蛋白质和基于碳水化合物的基质）将被优化用于打印。印刷产品将使用投影映射和超闪光分析进行感官评估测试，以进一步优化产品的质地特征。*

This project will explore the use of a 3D printer to print customized foods at a low cost, while still ensuring that the food is of high quality and is safe to consume. This project will first investigate sanitizing strategies to be employed by the user when printing food products. Food grade materials that can be used in the print cartridges of the printer will be identified and strategies for sanitizing the materials after use will be examined. This step will be validated through microbiological testing of the printing material before and after sanitation. The textural quality of the printed material will also be examined. Three food matrices (a lipid based, a protein based, and a carbohydrate based matrix) will be optimized for printing. The printed products will be tested with sensory evaluation using projective mapping and ultra-flash profiling to further optimize products for textural characteristics.******
