Leftover Dough Safety: If you also open the box of leftover flour kept in the fridge every night or morning and make rotis, then you are not alone. This is a very common habit in Indian homes. The reason is also clear – lack of time, getting ready early, children’s tiffin, running around in the office and avoiding the hassle of kneading the dough every time. Many people think that flour is just a mixture of flour and water, there is nothing bad in it, but is it really so? Is it safe to eat dough kneaded last night the next day? Can flour kept in the refrigerator go bad? And the biggest question – can this affect health? This is where things get a little serious, because flour is not just a simple mixture. It contains moisture and is rich in carbohydrates, which can make it a perfect place for bacteria and microorganisms to grow, especially if it is not stored properly.
Many times we think that everything becomes safe as soon as we keep it in the fridge, but the truth is that the fridge slows down the growth of bacteria, not stops it. These days, people are adopting the habit of batch cooking, food hacks and pre-preparation, which makes the question even more important – is it a good idea to use leftover flour or are we unknowingly taking risks with our health? In this article we will understand how long flour remains safe, how it spoils, how it should be stored and on what signs it should be thrown away immediately.
Is refrigerated flour safe?
The short answer is yes, but with some conditions. If flour is stored in a clean, airtight container and used within 24 hours, it is generally considered safe. The real concern is when the dough is left out for a long time, especially 8 to 10 hours or more.
Harmful bacteria like E.coli and salmonella can grow in flour at room temperature. Freezing slows down this process, but cannot stop it completely. As time progresses, the texture, taste and smell of the flour starts changing.
What changes occur in flour kept in the refrigerator?
Even as the dough cools, it continues to change inside:
-Gluten begins to strengthen, causing the dough to become hard and tight.
-The surface may dry out
-There may be slight sourness
-Nutrients like vitamin C and folate may decrease
For this reason, rotis made from freshly kneaded flour appear softer and lighter, whereas rotis made from old flour may be dry and less flavourful.
How long is it safe to keep flour?
According to food experts:
-Room temperature: 2–3 hours
-Refrigerator: 12–24 hours
-Freezer: up to 2 months
After 24 hours both safety and quality start declining.
How to refresh refrigerated flour?
If the dough seems hard:
-Add some lukewarm water
-Apply light ghee or oil on top
-Leave for 10–15 minutes before rolling.
Some people also add celery or a drop of lemon to reduce the sourness, but this cannot correct the problem.
signs of flour spoilage
If any of these signs appear, discard the dough immediately:
-Strong sour or strange smell

What are the better options?
