Characteristic ingredients in fermented rice noodles and the microorganisms used in making these noodles were investigated. Microorganisms including
Bacillus species, yeast, fungus, and
lactobacillus are present in the process in which fermented rice noodles are made. In the traditional processing of fermented rice noodles, protein and free amino acids are flushed out with hot water, decreasing these components in these rice noodles. Improvements in the noodle making process now prevent the loss of protein and amino acids. Fermented rice noodles now contain large amounts of functional components such as γ-aminobutyric acid and branched-chain molecules. In addition, the improved processing procedures for producing noodles results in a low level of allergens that could trigger immune responses in people with rice allergies.
Bacillus subtilis has high potential for application in production of hypoallergenic fermented rice noodles with high nutrient availability. Here we provide proposals for production and development of fermented rice noodles using Japanese rice.
