E392 – Rosemary extract
AntioxidantsDescription
Mixture of phenolic compounds (primarily carnosic acid, carnosol, rosmarinic acid, and rosmanol) extracted from the rosemary plant (Rosmarinus officinalis L.) using solvents like ethanol, acetone, or supercritical carbon dioxide; functions as an antioxidant to prevent rancidity and color changes in food.
Notes
Rosemary extract comes directly from the leaves of the rosemary plant (Rosmarinus officinalis), the same herb you might grow in your garden or use in cooking. To make the extract, manufacturers use solvents like water, alcohol, or carbon dioxide to pull out the beneficial compounds - mainly phenolic substances like carnosic acid and rosmarinic acid - that give rosemary its natural preservative powers. The process is similar to making a very concentrated herbal tea, but using industrial methods to capture specific beneficial molecules. As a natural antioxidant, rosemary extract prevents fats and oils from going rancid, which helps maintain the flavor, smell, and nutritional value of foods. You'll commonly find it in cooking oils, nuts, meat products, baked goods, and snack foods - anywhere manufacturers want to extend shelf life without using synthetic preservatives. It's particularly popular in "natural" or "clean label" products because consumers recognize rosemary as a familiar, wholesome herb. This is a completely natural additive that's perfect for vegetarians and vegans, and it's generally acceptable under all religious dietary laws. Many health-conscious consumers prefer it over synthetic antioxidants because it comes from a plant source and has been used safely in cooking for thousands of years. It's widely approved by food safety agencies and is often seen as a premium, natural alternative to synthetic preservatives.
