Notes

E103, known as alkannin or alkanet extract, is a natural red dye that comes from the roots of the Alkanna tinctoria plant, commonly called alkanet or dyer's bugloss. This plant grows wild in Mediterranean regions and has been used for centuries to create red and purple dyes. To extract the coloring, the dried roots are processed using oil or alcohol-based solvents, which pull out the pigmented compounds. The resulting extract has a distinctive reddish-purple color and works best in oil-based or fatty foods since alkannin is oil-soluble rather than water-soluble. This natural coloring agent is used to give foods an appealing red or reddish-purple tint, particularly in products that contain oils or fats where it can dissolve properly. You might find E103 in items like flavored oils, certain cheeses, oil-based sauces, and some traditional or artisanal food products. However, it's not as commonly used as other red food colorings because it can be more expensive to produce and doesn't work well in water-based products like soft drinks or candies. Being derived entirely from plants, E103 is naturally suitable for vegans, vegetarians, and most religious dietary requirements. However, despite its natural origin, this additive has actually been banned or restricted in many countries including the United States and European Union due to safety concerns - some studies suggested potential health risks, though the research remains inconclusive. As a result, you're unlikely to encounter E103 in most commercial foods today, as manufacturers have switched to safer, approved alternatives for red coloring.
