CIP in peanut butter manufacturing

Dears
Greeting
Is there any one have an experiement in producing peanut butter.
I wonder to know what additives must be add to protect the butter from deterioration and what the proper method and material that must use to do CIP for the equipments?

Regards

i have some experience. No need any additive, if you use quality ingredients and suitable packing material peanut butter would be stable min. 1 year.

Do you mean clean in place?

Many thanks for your reply
