procedures to start a small food product company?

Question

especially instant ready mix pastes

Answer 1

This sounds like a major operation, so I would choose to incorporate for tax and liability purposes.

Contact your local Certified Public Accountant (CPA). For a nominal fee they should be able to set you up on the business side of things.

Then while that is going on, look for space to manufacture and such.

Good luck and I hope you are prosperous.
