E163b - Delphinidin

Origin

Delphinidin is a natural anthocyanidin pigment, belonging to the flavonoid family. It is found in various fruits and vegetables, particularly those with a deep red, purple, or blue color. Common sources include grapes, blueberries, cranberries, pomegranates, and eggplant. Delphinidin is extracted from these sources using solvents, and then purified for use as a food additive.

Usage

As a food additive, delphinidin (E163b) is primarily used as a natural food coloring. It provides a range of colors, from red to blue, depending on the pH of the food product. It is used in a variety of food products, including beverages, jams, jellies, confectionery, and dairy products. Delphinidin also possesses antioxidant properties, which may contribute to the stability and shelf-life of the food product. There is no established ADI (Acceptable Daily Intake) for delphinidin as an additive, suggesting low toxicity at levels typically used in food.

Side Effects

Delphinidin is generally considered safe for consumption. As a naturally occurring pigment, it is metabolized by the body. There are no significant side effects reported in the scientific literature at levels typically consumed in food. However, as with any food additive, some individuals may experience allergic reactions or sensitivities. Individuals with known allergies to fruits or vegetables containing high levels of anthocyanins should exercise caution. High doses, far exceeding normal dietary intake, could potentially cause gastrointestinal discomfort, but this is not a common concern with its use as a food additive.

Regulatory Status

Delphinidin (E163b) is approved for use as a food coloring in many countries, including the European Union. It is subject to regulations regarding purity and labeling requirements. The European Food Safety Authority (EFSA) has evaluated the safety of anthocyanins, including delphinidin, and has concluded that they are safe for use as food additives within the established limits. Regulations may vary by country, so it's important to check local regulations regarding its use in specific food products.
