I'm going to establish a bakery industry where the product will be flat bread which is known as roti/chapati in asian continent. But I'm counfused about it's preservation for long time. I will make roti/chapati, then slightly bake them (half bake), then I pack them and sell to markets & shops. For this purpose, I need a way of preservation to keep them fresh for at least 3 days in normal temperature (without freezing). so friends please suggest me a way. Should I use preservative? If yes, then which will be the best & safe for people and also low cost?
