So if we want to reference this scientific article: “Testing consumer preferences for iced-coffee: Does the drinking environment have any influence?” by C. Petit and J.M. Sieffermann:
Petit, C., and J.M. Sieffermann. 2007. “Testing Consumer Preferences for Iced-Coffee: Does the Drinking Environment Have Any Influence?” 18 (1). Food Quality and Preference, 161-172. doi:10.1016/j.foodqual.2006.05.008.
And an in-text citation would look like this:
