中文摘要: 为获得以亚麻籽粉、明胶、魔芋胶为原料的最佳复合凝胶配方,构建富含膳食纤维的多凝胶复合型食品3D打印体系,该文以单因素和响应面试验对3种材料进行复配,利用黏度计、数字推拉力计、流动性检测、色差计和感官评价等方法,分析凝胶体系中黏度、硬度、流动性、色差及3D打印效果。结果表明,复合凝胶的最佳配比为明胶4 g、魔芋胶0.6 g、亚麻籽粉7 g、去离子水8.4 g。此条件制备的复合凝胶黏度为42 027.67 mPa·s,硬度为0.30 N,L*值为14.38,a*值为9.8,b*值为10.81,30 min时流动距离为0.56 cm,感官评分95,色差偏白、偏红、偏黄,因此该复合凝胶体系具有较好的支撑能力且打印成型效果最佳。
Abstract:In order to obtain the optimal compound gel formula using flaxseed powder,gelatin,and konjac gum as raw materials and construct a 3D printing system for multi-gel compound food rich in dietary fiber,the three materials were compounded by single factor and response surface experiments. The viscosity,hardness,fluidity,color difference,and 3D printing effect of the gel system were analyzed by means of a viscosimeter,digital push-pull force gauge,fluidity measurement,color difference meter,and sensory evaluation. The results showed that the optimum ratio of composite gel was 4 g gelatin,0.6 g konjac gum,7 g flaxseed powder,and 8.4 g deionized water.Under these conditions,the viscosity of the composite gel prepared was 42 027.67 mPa·s;the hardness was 0.30 N;the L* value was 14.38;the a* value was 9.8,and the b* value was 10.81. The flow distance at 30 min was 0.56 cm;the sensory score was 95,and the color was biased towards white,red,and yellow.Therefore,the composite gel system had good supporting ability and the best printing and forming effect.
