What is Food Biotechnology?What is Food Biotechnology?
Food biotechnology is the evolution of traditional agricultural techniques such as crossbreeding and fermentation.
It is an extension of the type of food development that has provided nectarines, tangerines and similar advancements.
It is a process that has resulted in improved nutrition, taste, quality and freshness of many foods today.
