What is Rosemary Extract Powder?
A natural antioxidant that is taken out of rosemary plants is called powdered rosemary extract. It has a brown-yellow powder appearance and is resistant to high temperatures. It is widely used in seasoning sauces, pet food and feed, and has antioxidant and anti-aging effects.
There are several main preparation processes for rosemary extract powder in China:
1. By boiling rosemary in water, the active ingredients are extracted using the solubility of water, and the filtered extract is concentrated by reduced pressure evaporation or freeze drying to obtain rosemary extract powder. This preparation process has low extraction efficiency and many impurities.
2. Put rosemary leaves in ethanol, soak them at room temperature or slightly higher temperature for a period of time, filter the soaked mixture, remove solid impurities, and then recover ethanol by distillation to obtain a concentrated extract. Ultimately, the concentrated mixture is dried to produce powdered rosemary extract. This preparation process can effectively extract the activity in rosemary, and it is low in cost, suitable for large-scale industrial production, and has little environmental pollution, and is widely used.

User asked question:
Q: Is it true that Rosemary extract powder can promote hair growth?
A: It is thought that powdered rosemary extract may help to stimulate hair growth in some ways.
