Plant based drinks are water-soluble extracts of legumes, seeds and (pseudo) cereals, with appearance similar to milk. Due to milk allergies, people consume plant based drinks as a milk alternative. We bought 17 different plain oat drinks available on the Slovenian market. We compared the labeled nutritional values of the oat drinks to the nutritional value of milk. The main ingredients are water, oats, oil and salt. Oat drinks contain natural present sugars. Their contents depend on the quantity of oats, which ranges from 10-16 %. Oat drinks contain some fats and lower amount of saturated fats compared to milk. Protein content is negligible. The main difference between milk and the other drinks is dietary fiber content, which milk does not have. For improvement of nutritional value calcium and vitamins D2, B2 and B12 are added to some of the oat drinks. Values of calcium were same as its values in milk. Fifty-two students from the Department of Food Science (Biotechnical Faculty Ljubljana) assessed sensory acceptability of the oat drinks with 9-point hedonic scale. Generally, the likeness of drinks was not high. The lowest assessed drink got an average score of 2.2 and the highest assessed drink‘s score was 5.7.
