近年来，日本的老龄化正在加剧。老年人不能很好地吞咽食物。因此，随着人口老龄化的加剧，人们对软性食品的需求也在不断增加。能让老年人饱餐一顿的美食实在太少了。一台打印软食品的设备，给了老人一个大梦想，大有希望。在这项研究中，我们的目标是开发一种3D可食用凝胶打印机，以制作老年人的软食品。我们做了一个3D可食用凝胶打印机的原型。打印机由注射泵和分配器组成。注射泵挤出溶液。分配器允许对三维物体进行建模。我们使用琼脂溶液作为油墨进行印刷。琼脂的胶凝作用在很大程度上取决于温度。由于琼脂溶液的物理交联网络是不稳定的，因此溶液的温度控制对于模具的最佳形状是重要的。我们使用3D可食用凝胶打印机成功地制作了凝胶和板状凝胶。另外，为了提高琼脂溶液的凝胶速度，我们更换了点胶器，目前正在进行印刷试验。利用可食用凝胶3D打印机打印了4种由琼脂和明胶制成的软质食品。由于硬度是影响食品质构的重要因素之一，因此对印刷软质食品样品进行了压缩试验，并对其硬度进行了测定。今后，应调整琼脂溶液或其他食品油墨的粘度，使其适合印刷。
In recent years, aging is progressing in Japan. Elderly people can't swallow the food well. So, the need of soft food is increasing greatly with the aging of the population. There are so few satisfying foods for the elderly to enjoy a meal. An equipment of printing soft food gives the elderly a big dream and is promising. In this study, we aim at developing a 3D edible gel printer in order to make soft food for the elderly. We made a prototype of the 3D edible gel printer. The printer consists of syringe pump and dispenser. The syringe pump extrudes the solution. The dispenser allows to model threedimensional objects. We use agar solution as the ink to carry out the printing. Agar’s gelation deeply depends on temperature. Therefore temperature control of the solution is important to mold optimal shapes because the physical crosslinking network of agar’s solution is instable. We succeeded in making the gels and plate-shape gel using the 3D edible gel printer. Further more, in order to increase the gelation speed agar’s solution, we changed the dispenser and the printing test is being done now. 4 kinds of soft food prepared from agar and gelatin were printed by the 3D edible gel printer. The compression tests of the printed soft food samples were done and their hardness is measured because the hardness is one of very important factors which influence the food texture greatly. In the future, the viscosity of the agar solution or other food ink should be adjusted to suitable for printing.
