The purpose of this paper was to explore the regulation of corn starch (CS) on tremella fuciformis polysaccharide-egg white protein-orange juice (TFP-EWP-OJ) composite gel to develop a new 3D printing material. The results showed that the cylinder of TFP-EWP-OJ composite gel with 0.12 g/mL CS added had the best 3D printing structure and highest printing accuracy. This was an indication that materials with suitable viscosity, hardness, and flowability were more suitable for 3D printing. The nozzle diameter and printing speed were selected to be 1.20 mm and 35 mm/s, respectively. The TFP-EWP-OJ composite gel had greater apparent viscosity and hardness as well as weaker fluidity and a denser network structure with increasing CS concentration. This suggested that the 3D printing performance of TFP-EWP-OJ composite gel can be improved by the incorporation of CS. Furthermore, fourier transform infrared spectroscopy (FT-IR) indicated that no new covalent bonds were formed between CS and the TFP-EWP-OJ composite gel.
本文旨在探究玉米淀粉（CS）对银耳多糖 - 蛋清蛋白 - 橙汁（TFP - EWP - OJ）复合凝胶的调控作用，以开发一种新型3D打印材料。结果表明，添加0.12 g/mL CS的TFP - EWP - OJ复合凝胶圆柱体具有最佳的3D打印结构和最高的打印精度。这表明具有合适粘度、硬度和流动性的材料更适合3D打印。喷嘴直径和打印速度分别选择为1.20 mm和35 mm/s。随着CS浓度的增加，TFP - EWP - OJ复合凝胶具有更高的表观粘度和硬度，以及较弱的流动性和更致密的网络结构。这表明通过加入CS可以改善TFP - EWP - OJ复合凝胶的3D打印性能。此外，傅里叶变换红外光谱（FT - IR）表明CS与TFP - EWP - OJ复合凝胶之间未形成新的共价键。
