Abstract

The invention relates to a producing method of rice and sweet potato composite convenient straight rice noodles, and belongs to the technical field of food processing.The producing method is characterized in that milled early long-grain nonglutinous rice and sweet potato starch serve as the raw materials, compound bacteria (lactic acid bacteria and yeast) are used for fermenting mixed rice noodles in a limited mode, nutritional factors of rice noodles are increased, and rehydration performance of the product is improved.Part of rice noodles is degraded in a limited mode in a fermentation process, produced ethyl alcohol makes rice noodles produce a porous structure in the twin-screw extrusion process, and the rehydration performance of the convenient straight rice noodles is further enhanced based on the strong absorption effect of alcohol for water and lipid, the permeation capacity and cavitation effect of infrared rays and the internal and external uniform drying effect during microwave pulse drying.The made convenient straight rice noodles are low in breakage rate, good in rehydration performance and excellent in food taste and quality.

Description

technical field [0001] The invention relates to a production method of rice and sweet potato composite instant straight rice noodles, belonging to the technical field of food processing. Background technique [0002] Rice flour is a traditional food with a long history and is loved by people. The traditional production process of straight rice noodles is: early indica rice → soaking → crushing → extrusion cooking → aging 1 → re-steaming → aging 2 → grooming → drying → cutting → sterilization → packaging. This kind of rice flour produced by extrusion has a tight molecular structure, low ready-to-eat property, difficult rehydration, and needs to be steamed before eating. So far, there is no technique for producing instant rice noodles by restricted fermentation using yeast. After fermentation, rice flour can not only generate sugars and various essential amino acids that cannot be synthesized by the human body, but also partially degrade starch and protein components. At the...
