Carbohydrates were the most abundant compounds in the condiments that also revealed a varied range of sugars with fructose, glucose, sucrose and trehalose detected in all the condiments. In respect to fatty acids, PUFA were prevalent with the great contribution of linoleic and alpha-linolenic acids among the different 32 detected fatty acids.

In a general way, the energetic value of the condiments and herbal infusions was very low and these plants revealed good nutritional properties that make them suitable for a balanced and diversified low caloric diet.
