If the baking continues, that is, from the end of the first explosion to the middle baking before the second explosion, or even the medium and deep baking from the first explosion to the second explosion, most of the sour aroma of the fermentation catalysis has been broken up, instead of the taste spectrum of the sugar browning reaction (Sugar Browning) and Mena reaction.
