Abstract

Rice noodles is a common food, but it is faced with the characteristics of hard texture and poor nutrition after aging. Quinoa is rich in dietary fiber and nutritious and can enrich the color and taste of rice noodles. In this paper, red quinoa is used as an additive, gelatinization time, quinoa added amount, and water added are selected as influencing factors on a single factor basis, and the hardness of rice quinoa gel is used as the response value to carry out experiments to optimize rice quinoa gelling Glue production process. The results show that the best process is: gelatinization time 30min, quinoa addition amount 30%, material to water ratio 1:2 (g/mL). The test product of this formula has uniform color, uniform gel, strong aroma, good taste and fine mouthfeel.
