Few topics interest so many different people in so many different ways as does the subject of food.Of course ,people need to eat to stay alive,grow and develop,and maintain good health.this need presents ongoing challenges for humans:finding ways of growing crops and raising animals in the most efficient way in the conditions available,inventing methods for competing successfully against plant and animals that also consume the crops and animals on which humans depend,developing methods for preserving foods to make sure they will be available at all times of the year,and so on.
It should be no surprise,then,to discover that a number of chemical techniques used to grow and process foods today have their roots in human cultures of many centuries ago.
Indeed,it has become a complex scientific industry that owes as much to the development of modern chemistry as it does to folk traditions and customs.
