Best before refers to the date up until which the food will be at its best quality. You will get the best taste, smell, texture and quality if eaten before this date. These details can usually be found on foods such as biscuits, crisps, dals, sauces etc. However, the food won’t go off straight away.
In some cases, you can still eat the food after the best before date, but you must store it correctly according to manufacturer’s guidelines. The food may not taste as nice, smell as nice, be as crispy and may not be as good quality. Overall best before means the food will be at its best quality.
