Peanut butter contain at least 90% peanuts; the remaining <10% usually consists of "...salt, a sweetener, and an emulsifier or hardened vegetable oil which prevents the peanut oil from separating". In the US, no product labelled as "peanut butter" can contain "artificial sweeteners, chemical preservatives, [or] natural or artificial coloring additives." Some brands of peanut butter are sold without emulsifiers that bind the peanut oils with the peanut paste, and so require stirring after separation. Most major brands of peanut butter add white sugar, but there are others that use dried cane syrup, agave syrup, or coconut palm sugar. Organic and artisanal
Peanut butter the peanuts are sent to grinding to be manufactured into peanut butter. The peanuts are then sent through two sizes of grinders. The first grinder produces a medium grind, and the second produces a fine grind. At this point, salt, and a vegetable oil stabilizer are added to the fine grind to produce the peanut butter. This adds flavour and allows the peanut butter to stay as a homogenous mixture. Chopped peanuts may also be added at this stage to produce “chunky” peanut butter. Before packaging, the peanut butter must first be cooled in order to be sealed in jars.
