Sometimes it doesn't but the organizers say their mission isn't only positioned on pumpkin pulverization.

有时有，但是组织者说他们的任务不仅仅是给南瓜授粉。

The goal of all this pulverization is to increase the surface area of that bite of food by breaking it down into increasingly tiny pieces, to prepare it to encounter more enzymes in step four: chemical digestion.

所有这些粉碎的目标是通过将食物分解成的碎片增加食物的表面积，为它在第四步遇到更多的酶做好准备：化学消化。
