This is a natural gelling substance that is most often obtained from apples and citrus fruits. Pectin is also a water-soluble fibre. This type of fibre swells when exposed to water and gives a quick feeling of fullness. It also affects the proper functioning of the intestines. Pectin is added to yoghurt for its thickening and stabilising functions. Thanks to this, you can get the right, desired consistency. Pectin is considered safe for health.
