Introduction
Hydroxytyrosol is a naturally occurring polyphenol primarily found in olives and their products, such as olive oil and olive leaves. It is widely studied for its outstanding antioxidant properties and has numerous applications in the food and cosmetic industries. As a powerful antioxidant, hydroxytyrosol helps reduce oxidation in foods, extending shelf life and preserving flavor. Due to its health benefits, hydroxytyrosol is often added to health foods to support cardiovascular health, boost immunity, and reduce inflammation.

China
Hydroxytyrosol has been approved as a new food additive in China. It is used as an antioxidant in vegetable oils (food category 02.01.01) to delay oxidation, with a maximum level of 0.05 g/kg. This approval applies to hydroxytyrosol produced from tyrosine through a process involving fermentation with Corynebacterium glutamicum, followed by catalytic conversion, separation, and purification.
The approval process spanned just over 6 months from acceptance to public consultation, and only about 9 months to get official approval.

US
In the US, hydroxytyrosol has been approved as a Generally Recognized as Safe (GRAS) substance. Notably, another GRAS substance is hydrolyzed aqueous olive pulp extract, a phenolic preparation. Hydroxytyrosol is primarily intended for use as an antioxidant and antimicrobial in beverages, fats and oils, fresh and processed fruits and vegetables and juices, and gravy and sauces at use levels of 5.0 milligrams per serving.
EU
In accordance with Commission Implementing Decision (EU) 2017/2373, hydroxytyrosol derived from chemical synthesis has been authorized as a Novel Food. The authorized food categories include fish and vegetable oils (excluding olive oil and olive pomace oil), as well as spreadable fats, with maximum levels set at 0.215 g/kg and 0.175 g/kg, respectively. Additionally, the European Food Safety Authority (EFSA) has issued a scientific opinion on the safety of hydroxytyrosol as a Novel Food. The opinion states that the expected daily intake of hydroxytyrosol from these uses is comparable to or even lower than the exposure from consuming olive oil and olives. Therefore, the panel concluded that hydroxytyrosol is safe under the specified uses and use levels.
Australia and New Zealand
According to the “Food/Food Ingredients Record of Views” by Food Standards Australia New Zealand (FSANZ), the safety assessment for olive fruit extract notes that there are no safety identified at levels of use (up to 20 mg/day of hydroxytyrosol). Therefore, it can be concluded that a daily intake of 20 mg of hydroxytyrosol is considered safe in Australia and New Zealand.
