For your questions:
* The amount of ingredients necessary to make items of 10t
It's variety with each time we receive material. Some time, material is good, the yeld is low; but some time, it's so so, the yeld is higher. As last 510ctn, we use frozen material, the yeld is much higher. And it's even variety because of the worker's skill. So we can't say it for sure.
But we always sure that the percentage of food additive we used is follow the procedure chart we agreed. Please believe in that.
