FAQ ：Resveratrol
1. What is Paprika Oleoresin?
Paprika Oleoresin (also universally known as Capsicum Oleoresin, CAS 68917-78-2 / 8023-77-6) is a natural functional ingredient extracted and refined from the fruits of chili peppers (Solanaceae Capsicum genus) via standardized physical processes. It is a multi-functional additive that integrates pungency enhancement, flavoring and coloring, with core active components including capsaicinoids, natural paprika red pigment and various volatile flavor compounds.
2. Is Paprika Oleoresin safe for food and industrial applications?
Yes, Paprika Oleoresin is completely safe when used within the standard-specified dosage range. It is not a chemically synthesized illegal additive, but a natural extract derived purely from chili peppers via physical extraction. Its safety has been strictly evaluated and officially recognized by the Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO), as well as food safety authorities in the US, EU, China and other countries worldwide. It is a GRAS (Generally Recognized as Safe) natural food ingredient, with no toxic residues or adverse effects when used in accordance with international food safety standards.
3. What is the difference between Paprika Oleoresin and regular chili powder?
Paprika Oleoresin has significant advantages over traditional chili powder for industrial applications, making it a more cost-effective pungency solution:
Ultra-concentrated pungency: 1kg of 4% capsaicin Paprika Oleoresin delivers the same pungency as 80-120kg of dried chili powder, greatly reducing transportation and storage costs.
Superior stability: It solves the pain points of chili powder such as easy mold growth, flavor loss and short shelf life, with a shelf life of up to 24 months.
Better dispersibility: It can be evenly dispersed in oil, water and emulsion systems, ensuring consistent and stable pungency throughout the product shelf life, which cannot be achieved by chili powder.
Higher value: It can be customized by pungency, solubility and color, to precisely match different industrial application needs.
