Why Proper Storage Is Crucial
Millets, whether whole grains like jowar and ragi or ground into flour, are susceptible to spoilage. They contain natural oils that, when exposed to air, heat, and light, can turn rancid, resulting in a bitter taste and unpleasant smell. Additionally,
the warm and humid climate prevalent in many parts of India creates an ideal environment for pests and mould. Proper storage is not just about preventing waste; it is about preserving the taste, texture, and vital nutrients that make millets a superfood.
Storing Whole Millet Grains
Whole millet grains have a longer shelf life than flours if stored correctly. Start by ensuring the grains are clean and completely dry, as any moisture can lead to spoilage. Sun-drying is a traditional and effective method to remove any residual moisture. Once dry, transfer the grains to a clean, airtight container. Glass jars or steel containers with tight-fitting lids are excellent choices. Store the container in a cool, dark, and dry place like a pantry or kitchen cabinet, away from the stove and direct sunlight. When stored this way, whole millets can last for a year or even longer.
The Challenge with Millet Flours
Millet flours, such as bajra, jowar, and ragi atta, are much more delicate than their whole-grain counterparts. The process of grinding increases the surface area exposed to oxygen, which accelerates the process of oxidation and causes the natural oils to go rancid quickly. Bajra flour is particularly notorious for turning bitter, sometimes within just a couple of weeks, due to its higher fat content and active enzymes released during milling. This is why many traditional households grind millet flour in small batches as needed.
Best Practices for Storing Flours
For the freshest flavour, it is always best to buy millet flours in small quantities that you will use within a few weeks. For short-term storage, an airtight container in a cool, dark pantry is sufficient. For longer-term storage, the refrigerator or freezer is your best friend. Transfer the flour to an airtight container or a freezer-safe bag and store it in the fridge for up to six months or the freezer for up to a year. This cold environment significantly slows down oxidation and keeps the flour fresh.
Natural Pest Repellents for Indian Kitchens
In India's climate, keeping pests like weevils at bay is a constant effort. Thankfully, several traditional kitchen tricks work wonders. Adding a few dried bay leaves (tej patta), whole dried red chillies, or a few cloves to your container of whole millets can help repel insects. Some also suggest using dried neem leaves, which have natural insecticidal properties. Ensure these items are completely dry before adding them to your grains.
How to Spot Spoilage
Always trust your senses to check if your millets or flour have gone bad. The most obvious sign is a change in smell; fresh millets have a neutral, slightly nutty aroma, while spoiled ones will smell sour, musty, or rancid. Visually inspect for any signs of mould, discoloration, or clumps, which indicate moisture damage. Finally, look for any evidence of insect infestation, such as tiny bugs or larvae. If you notice any of these signs, it's safest to discard the product.
