How long can dough safely cold-proof in the fridge?

Food Safety & Storage

Research here does not establish a safe maximum time for cold-proofing dough in a household refrigerator. The studies examine fermentation, dough quality, or visible mould—not a general food-safety limit in hours or days.

One study reported that dough made with a specially selected yeast strain still produced bread dough normally after a week at 5 °C, but that was a laboratory yeast experiment, not proof that ordinary dough is safe for a week. Another study assessed refrigerated-dough shelf life by watching for visible mould, but it did not provide a general cold-proofing time. So this research cannot support a reliable number for home baking. A question these papers can answer is: "How does 7% amaranth flour affect shelf life?"

What this answer does not cover

• This synthesis uses titles and abstracts, not a full-text systematic review.
• Bibliographic index coverage and metadata can be incomplete or delayed.
• Retraction and publication-status metadata can be incomplete across connected indexes.
• Paper quality and risk of bias were not independently assessed.
• The reviewed material does not establish a household food-safety limit for refrigerated dough.
• The studies used different dough types, fermentation methods, temperatures, and ingredients, so their results cannot be combined into one maximum storage time.
• Several papers concern dough quality, yeast activity, or contamination rather than safety during cold-proofing.
• The review covered supplied abstracts only, not full papers, methods, or food-safety guidance.
