What is the function of egg in noodles?

Improves colour: When eggs are used, the noodles not only get a richer taste but also a rich yellow colour, which is an essential attribute of quality wheat noodles.

Enhanced texture: Eggs make noodles more robust, less likely to break, and tender at the same time, making them easier to handle.

Enriched Flavour: Eggs have a robust, savoury flavour that imparts the noodles a delectable and distinctive taste, making them more tasty and palatable.
