E163f - Petunidin

Origin

Petunidin is a naturally occurring anthocyanidin, a type of plant pigment belonging to the flavonoid family. It is found in various fruits, vegetables, and flowers, contributing to their red, purple, or blue hues. The specific color depends on factors such as pH, temperature, and the presence of other compounds. Petunidin is derived from the glycosylation of petunidin aglycone.

Usage

As a food additive, petunidin (E163f) is used as a natural food coloring. It can be used in a variety of food and beverage products to impart a red, purple, or blue color. Examples include fruit juices, jams, confectionery, dairy products (yogurts, ice cream), and baked goods. The stability and color intensity of petunidin can be influenced by factors such as pH, temperature, and the presence of other food components. It is also being investigated for its potential health benefits as an antioxidant.

Side Effects

Anthocyanins, including petunidin, are generally considered safe for consumption. There are no significant side effects reported at levels typically consumed in food. However, as with any food additive, some individuals may experience allergic reactions or sensitivities. No specific ADI (Acceptable Daily Intake) has been established for petunidin by major regulatory bodies like EFSA or FDA, which often indicates a low level of concern for toxicity at typical usage levels. Studies have shown that anthocyanins are poorly absorbed in the gut, with most being excreted. Further research is ongoing to fully understand the long-term effects of high anthocyanin intake.

Regulatory Status

Petunidin, as part of the E163 (Anthocyanins) group, is permitted for use as a food coloring in the European Union under Regulation (EC) No 1333/2008 on food additives. The specific conditions of use and maximum levels are defined in Annex II of the regulation. In the United States, anthocyanins are generally recognized as safe (GRAS) and are permitted for use as color additives, although specific regulations may apply depending on the source and application.
