Resveratrol extracts from different raw materials have differences in source, content, safety and application, which are analyzed below:
Tiger Balm Extract:
Content: The roots and rhizomes of Tiger Balm are the main parts of the plant for extracting natural resveratrol, and its resveratrol content is high, up to 4.12~8.94mg/g.
Safety: Despite the high content of resveratrol in Tiger Balm, its safety is difficult to be fully recognized in the international arena, which may limit its use in certain markets or applications.
Applications: Tiger Balm extract is commonly used where high levels of resveratrol are required, but its application may be limited due to safety concerns.
Grape Extract:
Content: Grapes contain relatively low levels of resveratrol, which is mainly found in the skins, with 100 g of fresh red grapes containing approximately 0.15 mg of resveratrol. However, wine (especially red wine) is an important dietary source of resveratrol.
Safety: Grapes are safer and more biologically active as a food ingredient, making grape extracts more popular in the international market.
Application: Grape extracts are commonly used in health care products and cosmetics, and are favored for their safety and biological activity.
Peanut extract:
Content: The content of resveratrol in peanut can reach three parts per million, although the content is not as high as that of tiger nuts, but peanut, as a common crop, has a wide range of raw material sources.
Safety: As a food raw material, peanut is safe and suitable for resveratrol extraction.
Applications: Peanut extracts can be used in nutraceuticals, food additives and other fields to provide the health benefits of resveratrol in products.
Other Plant Extracts:
Resveratrol is also found in a variety of plants such as mulberry, blueberry, pomegranate, cranberry and so on. The amount of resveratrol in these plants varies, but is usually lower than that of thuja and grapes.
These plant extracts may be used in combination with other ingredients for their specific flavor, nutrient content, or bioactivity to provide more comprehensive health benefits.
