In the malting process, which component undergoes a significant breakdown due to enzyme action?

During the malting process, the endosperm undergoes a significant breakdown due to enzyme action. The endosperm is the starch-rich tissue that provides nutrients to the developing embryo in the seed. When barley grains are soaked in water and allowed to germinate, enzymes such as amylases become active and break down the starches present in the endosperm into simpler sugars. This process is crucial because the sugars released during this breakdown are essential for yeast fermentation during brewing.

As the malting process continues, the starches are converted into fermentable sugars, which will later be utilized by the yeast to produce alcohol and carbonation in the beer-making process. This enzymatic activity in the endosperm is a key aspect of preparing the grains for brewing, as it lays the groundwork for fermentation efficiency and ultimately influences the flavor and body of the beer.

The other components mentioned, such as the cell wall structure and pericarp, do not undergo the same level of enzymatic breakdown during malting. The aleurone layer, while active during the malting process and involved in the enzyme production, primarily supports the breakdown but is not the main component being degraded. Therefore, it is the endosperm that plays the dominant role in this crucial
