ANSWER

You could use plant-based non-dairy creamers or vegan creamers such as soymilk powder as a substitute to non-dairy creamers in instant beverages (Riaz, 2005). Commercial non-dairy creamers has a high content of trans-fatty acids (Wang & Liu, 2014). Soymilk powder shows a similar resemblance in appearance as instant powder and creamers in coffee and nutritional drinks (Riaz, 2005).
