The ingredient, launched in the US last November, is intended for supplements but could also be used in other products, said Pedro Vieira, marketing manager Kemin Health Europe With 50 per cent of Europeans and 62 per cent of Americans already classed as overweight, the potato extract is aimed at this rapidly expanding weight loss and management market. "Based on Euromonitor data from last year the total retail value for slimming products in Europe (eastern/western) is €809 million. This value is distributed amongst Slimming tablets, slimming teas, meal replacement slimming products and other," Vieira told NuraIngredients.com. The benefits of the ingredient are reported to be related to the proteinase inhibitor II (PI2), a protein naturally found in white potatoes. The ingredient, when taken in the form of a tablet or capsule, one hour before taking a main meal, is said to enhance the body's own release of cholecystotinin (CCK), an appetite-suppressing hormone that work by delaying the emptying of the stomach (gastric emptying) and thereby promoting the feeling of fullness. Eleven clinical studies are reported to have demonstrated PI2's benefits, with some of these trials done using PI2 and some with Slendesta, said Vieira. The trials also support the safety and efficacy of the ingredient, said Kemin. Kemin's flagship proprietary product, FloraGLO lutein, is derived from purified marigold extract. Slendesta is Kemin's newest ingredient.
