As human population grows, it was followed by the increasing in the need of food and it gave significant impact in demand and competition among food industries. From various kind of food that consumed by people, there are a view which was prefered considered from its price, benefit, and other kind of consideration.

It is a sure thing if Six sigma could be accomplished, it would cause great deal to the company.
