生地は冷蔵庫でどのくらいまで安全に低温発酵できる？

Food Safety & Storage

Research has not established one universal safe maximum for cold-proofing dough in a home refrigerator. For the specific refrigerated steamed-bread dough studied, 24–48 hours was suitable for quality, while 72 hours caused noticeable quality problems; this should not be treated as a general food-safety guarantee for every dough.

The closest study tested refrigerated, selenium-enriched Chinese steamed-bread dough and found its best reported quality after 24–48 hours. After 72 hours, the dough lost strength and stretch, and the baked bread showed separation between crust and crumb. Other research describes mould during refrigerated storage or microbial contamination in dough, but does not establish a single safe cold-proofing limit for ordinary homemade dough. Keep dough continuously cold, use a clean covered container, and discard it if it develops mould, an unusual odor, or other spoilage signs. A question these papers can answer is: "How does Refrigeration for 24-48 h affect dough extensibility?"

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 evidence reviewed covers different products and fermentation methods rather than ordinary homemade bread dough as a whole.
• The 24–48-hour finding mainly concerns product quality in a specific selenium-enriched Chinese steamed-bread study, not a validated food-safety cutoff.
• The studies do not establish how refrigerator temperature, ingredients, salt, hydration, yeast amount, or handling change the safe storage time.
• The review was based on supplied titles and abstracts rather than full-text articles, so important methods and safety details could not be checked.
