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

有时候没有，但组织者说他们任务不给南瓜授。

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.

所有这些目标通过将食物分解成越来越小片来增加食物表面积，为它在第四步遇到更多酶做好准备：化学消化。
