title: Native fructose extracted from apple improves glucose tolerance in mice.
abstract: Fructose is one of the most abundant monosaccharide in nature. It is also the sweetest naturally occurring carbohydrate. Since decades, fructose used for food preparations is not provided by fruit or vegetable but by a chemical process of starch or inulin conversion. We processed a new method of fructose extraction from apple and investigated the acute and long term effect of this carbohydrate on glucose metabolism in C57Bl6/j mice. By using the glycemic index (GI), we have shown that one of the sugars obtained from apple, FructiLight, has a very low impact on glycemic and insulin response during acute treatment compared to other sugars. This carbohydrate, essentially constituted by fructose, has also beneficial properties when administrated for long term treatment. Indeed, as two other sugars extracted from apple (FructiSweetApple and FructiSweet67), FructiLight exposure during 21 weeks in beverage has promoted an enhancement of glucose tolerance compared to glucose treatment without affecting food intake and weight. All these results indicate that apple-extracted sugars and more precisely fructose from these fruits could be a promising way to produce new food and sweet beverages.
