Cal. Food & Agric. Code § 64014

“Processing” means separating, standardizing, pasteurizing, sterilizing, evaporating, condensing, canning, bottling, packaging, or otherwise preparing milk fat in milk, cream, or skim milk for market, or of using it to manufacture or produce any dairy product. “Processing” does not, however, include separating by a producer, on the dairy where the milk is produced nor shall milk so separated be deemed to have been processed. Placing bulk milk, cream, or skim milk in cans for transportation to a handler from the dairy is not canning as that term is used in this section.
