A hint of the exotic in new t-vital
A new brand in the German functional foods sector is t-vital, belonging to eastern German dairy co-operative Wittstock. The products in the range are based on the exotic South American tuber topinambur.
Topinambur is a relative of the sunflower and its tubers contain a high content (8%) of the fructose polysaccharide inulin. This sweetens while delivering only a quarter of the energy of carbohydrates like starch and sugar. Inulin is metabolised by the body into up to 85% fructose and 15% glucose and dextrose.
The first t-vital product to be launched by Wittstock is buttermilk with topinambur (protein 3.2%, fat 0.4%). The launch has led to the establishment a new branch of the farming industry in the fields of Mark Brandenburg near Berlin. Local farmers have begun to grow the tuber, which has long been regarded as having important medicinal properties.
Contents usually include well over 500mg of potassium per 100g, offering a healthy enzyme household in the body and improved nerve and muscle functions. Other minerals present include phosphate, calcium, magnesium, sodium and iron.
