Grapefruit Seed Extract (GSE): Products & Application

Natural bioflavonoids are a valuable ingredient of grapefruit seed extract and just one of several quality features. The flavonoid content alone says little about the quality and effectiveness of GPE. It is important that it is a full-spectrum extract. CitroBiotic is a so-called full-spectrum extract. It maintains the balance or the spectrum of the various grapefruit bioflavonoids as found in the fruit, without over-representing any single flavonoid. Flavonoids are the yellowish-orange (flavus= Latin: blond, yellow) plant compounds. They are among the most important active ingredients in phytotherapy. Many flavonoids are also a food. For this reason, they are also referred to as "semi-essential". If we eat a diet rich in flavonoids, we are definitely doing our body something good, because flavonoids have considerable antioxidant potential. They are widespread in the plant kingdom and are found in practically all fruits and vegetables and in some nut and grain varieties. Flavonoids are thermostable, meaning they are only slightly lost during cooking. Very flavonoid-rich foods include broccoli, endives, onions, kale, lingonberries, cranberries, tomatoes, citrus fruits (especially grapefruit), but also red wine (in moderation, please!) and green tea. The valuable grapefruit ingredients differ in the fruit, the peel, and the seeds. In the fruit, i.e. the pulp, there are the bitter-tasting glycoside naringin as well as ascorbic acid and thiamine. The outer yellow peel contains pinene, limonene, linalool, citraldehyde and has an oil content of 20%. The grapefruit seeds contain numerous bioflavonoids, including naringin, hesperidin, neohesperidin, quercetin, kaempferol, rutin, limonin, poncirin, as well as other ingredients. For GPE production, the seeds and the white parts of the peel are used, i.e. the parts that we usually remove when normally consuming a grapefruit.
