Area of Science:

  • Food Science and Technology
  • Nutritional Biochemistry
  • Molecular Gastronomy

Background:

  • Traditional noodles lack diverse functional compounds.
  • Rooted plant flours offer potential nutritional and sensory enhancements.
  • Limited research exists on volatile compounds and health benefits of root-fortified noodles.

Purpose of the Study:

  • To investigate volatile flavor components and functional compounds in rice and qingke noodles fortified with various rooted plant flours.
  • To analyze the impact of these flours on sensory profiles, nutritional value, and potential health benefits.
  • To explore the molecular mechanisms behind the health-promoting effects of these fortified noodles.

Main Methods:

  • Gas chromatography-mass spectrometry (GC-MS) for volatile organic compound (VOC) analysis.
  • Identification and quantification of functional compounds like polyphenols, resistant starch, and polysaccharides.
  • Molecular docking simulations to predict interactions with metabolic targets.

Main Results:

  • Key VOCs (esters, aldehydes, terpenes) identified, contributing to umami, sweet, and earthy notes.
  • Highland barley flour showed high phenolic compounds and carotenoids, improving antioxidant activity and reducing glycemic index.
  • Gongmi flour enriched noodles with GABA and rutin, suggesting benefits for metabolic and cardiovascular health.
  • Molecular docking predicted cardioprotective and anti-diabetic effects of specific VOCs.

Conclusions:

  • Rooted plant flours significantly enhance the nutritional and sensory properties of noodles.
  • Fortified noodles possess valuable functional compounds with antioxidant, anti-inflammatory, and cholesterol-lowering potential.
  • This research provides a framework for developing functional foods that combine sensory appeal with health efficacy.
