Many foods in our kitchens come with expiry dates, but some can last indefinitely when stored properly. Honey, known for its low moisture content and high acidity, is one of the few foods that never truly expires. White rice can remain fresh for up to 30 years if kept in airtight containers, while brown rice spoils faster due to its natural oils. Salt and sugar serve as effective natural preservatives by removing moisture and preventing bacterial growth, allowing them to last indefinitely. Soy sauce, with its high salt content, has a long shelf life even after opening, provided it is refrigerated. White distilled vinegar is another long-lasting item due to its high acidity, which prevents spoilage. Lentils and pulses can remain edible for years if kept dry, while powdered milk can last for years in cool, dry conditions. Additionally, cornstarch and instant coffee powder can stay fresh for long periods when protected from moisture.
