No, that's a common misconception.
When FSTA was created in the late 1960s, it was called Food Science & Technology (i.e. FSTA). However, the field of food research has changed a lot since then, and FSTA has evolved too.
In addition to the core areas of food science, food technology and nutrition, FSTA includes relevant content across a host of related fields, including agriculture, microbiology, viticulture and oenology, biotechnology and much more.
