manufacturing process

Mix the dough first, that is, add fresh yeast or old flour (fermented flour) to knead the dough to a certain extent, then add appropriate amount of soda ash and salt to knead the dough, and then cut it into strips with a thickness of 1cm and a length of about 1cm. Every two strips are stacked on top of each other, pressed with narrow wooden strips in the middle, rotated, stretched and fried in a hot oil pan.

Make it swell into a crisp and fragrant fried dough stick. During fermentation, yeast secretes enzymes (mainly glucoamylase and alcoholase) because they propagate in dough.

A small part of starch is converted into glucose, and then from glucose to ethanol, producing carbon dioxide gas. At the same time, it also produces some organic acids, which react with ethanol to produce aromatic esters.
