Question

while purchasing canned food it's expired date should be changed​

Answer 1

Answer:

The ‘best before’ date guarantees certain properties of the product to be effective up to this point. Once the date has passed, it may just lose its freshness, taste, aroma or nutrients. But it does not necessarily mean that the food is no longer safe to eat. In order to decide whether the food is still edible, one should rely on his/her senses (sight, smell and taste). The product should not be consumed if you find that the taste has been compromised, odour and appearance is odd or it’s exhibiting strange consistency. Note: this only applies to unopened shelf-stable product. Once a sealed product is exposed to air it is prone to contamination. Thus, the ‘best before’ date no longer applies to it.
