Food Grade Bitter Agent Grapefruit Extract Naringin 98%

Brief Introduction of Grapefruit extract Naringin

Naringin belongs to the group of flavonoids. Pure naringin is a yellowish powder.

Naringin is a flavanone-7-O-glycoside between the flavanone naringenin and the disaccharide neohesperidose. The flavonoid naringenin occurs naturally in citrus fruits, especially in grapefruit, where naringin is responsible for the fruit's bitter taste. .

Naringin is the major flavonoid glycoside in grapefruit and gives grapefruit juice its bitter taste. It is metabolized to the flavonone naringenin in humans.

Narinigin exerts a variety of pharmacological effects such as antioxidant activity, blood lipid-lowering, anticarcinogenic activity, and inhibition of selected cytochrome P450 enzymes including CYP3A4 and CYP1A2, which may result in several drug interactions in-vitro.

So how is the grapefruit extract Naringin produce effect to our body ?

Naringin and its aglycone naringenin belong to this series of flavonoids and were found to display strong anti-inflammatory and antioxidant activities. Several lines of investigation suggest that naringin supplementation is beneficial for the treatment of obesity, diabetes, hypertension, and metabolic syndrome. A number of molecular mechanisms underlying its beneficial activities have been elucidated. However, their effect on obesity and metabolic disorder remains to be fully established. Moreover, the therapeutic uses of these flavonoids are significantly limited by the lack of adequate clinical evidence. This review aims to explore the biologic activities of these compounds.

Naringin in Food and beverage application :

Naringin Product has a little flavor, but a bitter taste making the product an additive in grapefruit juice. This solid also has antioxidant properties and is applied in confectionery goods, beverages and jams.

Bitter substances, such as naringin, is intended to be added in order to give the food of the bitter taste, in general, a threshold that people can perceive the naringin are said to be about 100ppm ( "latest fruit juice, fruit drinks encyclopedia" Asakura Shoten, October 1997), to improve the flavor of food by naringin was considered that it is necessary to formulate a naringin in excess of at least 100ppm in food.

Naringin in Feed Additive as a sensory additive ( Flavouring Compound )

Naringin, a flavanone glycoside, occurs naturally in the pericarp of citrus fruit, and particularly of grapefruit (Citrus paradisii) where it is the predominant flavanoid found and is responsible for the bitter taste associated with the fruit. It is currently listed in the register of flavouring substances, allowing its use in food without restriction. Data from chronic oral feeding studies in rats indicated that a use level up to 5 mg naringin/kg complete feed is safe for all animal species with a considerable margin of safety.

The use of naringin in animal nutrition is not expected to cause harm to the environment. Because its function in the feed is basically the same as in food.
