When you talk about mixing the 植物蛋白 with 三聚氰胺, you only consider pure 植物蛋白 mixed with 三聚氰胺. What if someone uses dirty and cheap stuff to reduce the amount of 植物蛋白 required? That's my point.

1)N% of regular soybean powder

2)N% of regular starches

3)sale price of soybean powder

4)sale price of starches or gypsum

5)sale price of 三聚氰胺
