What did you observe in the chewed biscuit?

In the chewed biscuit, I observed a breakdown of its original structure, with noticeable changes in texture and moisture content. The once crisp and dry surface became softer and more pliable, indicating saliva's role in digestion. Additionally, the flavor was likely enhanced due to the mixing of saliva with the biscuit, releasing its ingredients more effectively. Overall, the transformation highlighted the impact of chewing and the initial stages of digestion.
