What is Grapefruit seed extract (Naringin powder)?

Grapefruit seed extract (Naringin powder, Citrus paradisi extract) is a flavanone-7-O-glycoside between the flavanone naringenin and the disaccharide neohesperidose. The flavonoid naringin occurs naturally in citrus fruits, especially in grapefruit, where naringin is responsible for its bitter taste. In commercial grapefruit juice production, the enzyme naringinase can be used to remove the bitterness created by naringin. In humans, naringin is metabolized to the aglycone naringenin by naringinase present in the gut.
When naringin is treated with potassium hydroxide or another strong base and then catalytically hydrogenated, it becomes a naringin dihydrochalcone, a compound roughly 300–1800 times sweeter than sugar at threshold concentrations.
