Abstract: The present invention provides a composition comprising thylakoids, which regulates the gut microbiota, leading to an increased colonisation probiotic bacteria, and a decreased growth of potentially harmful bacteria. According to an embodiment, a composition comprising thylakoids is a prebiotic agent.

Abstract: The present invention relates to the use of a composition comprising at least one cell membrane fraction or parts thereof, for the reduction of lipolytic activity and/or to retard fat digestion, suppress appetite, body weight and/or lower blood lipids. The invention also relates to the use of said hydrophobic peptide in a pharmaceutical as well as a food composition and methods of treating a mammal with said composition.

Abstract: The present invention relates to a process on a large industrial scale for the production of thylakoids, from photosynthetic organisms, such as from green plant leaf material, to be used as ingredients in food, or additions to food, or dietary supplements, or pharmaceuticals for the purpose of preventing overweight, promoting satiety, reducing food intake, reducing bodyweight, reducing blood insulin concentration and reducing blood fats and percentage body fat in humans and animals.

Abstract: Use of a composition comprising cell membrane, or hydrophobic peptides derived from said cell membrane, for the reduction of lipolytic activity, retardation of fat digestion, suppression of appetite, decrease of body weight and/or lowering of blood lipids. Satiety for fat is mainly driven from the intestine. By the contact of fat with the intestinal mucosa, various satiety peptides are released, thus suppressing appetite and food intake. A reduced rate of fat digestion could optimise the satiety for fat, through prolonged release of satiety peptides. Fat digestion can be retarded by reduction of the lipolytic activity of pancreatic lipase. The examples show that fractions of plant cell membranes (thylakoids) inhibit the lipolytic activity of pancreatic lipase.
