For dry storage, yes. BPA-free sounds great at first and could help you make a decision to buy the product, but new research adds to growing evidence that BPA-free alternatives may not be as safe as consumers think, and the chemical can get into the food with excessive microwaving. In this instance, for storing dry food, you should be okay because these are dry ingredients that you will be using for cooking. However, if you can, choose a glass food storage container which may seem expensive at first sight, but this is the ultimate long-term winner in terms of quality material that is free of odors and is more durable.
