A deep dive into Ohio's permitted shelf-stable categories — what's allowed, what's restricted within each category, and the science behind Ohio's food safety rules.
Ohio's cottage food rules are built on two food science measures. A food is considered potentially hazardous if it has a pH greater than 4.6 AND a water activity greater than 0.85 — conditions that allow harmful bacteria to grow. Foods below those thresholds at equilibrium are shelf-stable and safe without refrigeration.
An acidified food is a low-acid food to which acids or acidic ingredients have been added — like pickles, most salsas, and vinegar-based hot sauces. Even if the finished pH is below 4.6, the acidification process itself requires a licensed cannery and a Process Authority review. You cannot self-certify an acidified food for cottage food sale using a pH meter, no matter what the reading shows.
Ohio's broadest permitted category — virtually any non-potentially hazardous baked item qualifies, with specific exceptions around fillings, frostings, and fruit use.
Permitted because high-acid fruits naturally drop the pH below 4.6 without added acid. Ohio allows jams, jellies, marmalades, preserves, and fruit butters under cottage food.
A broad and lucrative category for Ohio home producers. High sugar content and the absence of protein-rich ingredients keeps most candy well within the safe zone.
Dry goods are generally Ohio's most straightforward category — no moisture, no temperature concerns. The main rules involve the source of any fruit ingredients.
Ohio has a special carve-out for small-scale producers of honey, maple syrup, sorghum syrup, and apple products — but with a strict sourcing requirement and sales channel restrictions for some.
Ohio has no annual gross sales cap on cottage food or home bakery products. Every shelf-stable item on this page — jams, cookies, granola, candy — can be sold in unlimited quantities without triggering any revenue threshold. Scale your business at whatever pace your kitchen and your market will support.
