Description

Crocin is a natural carotenoid pigment and the primary bioactive compound responsible for the characteristic color and many health-promoting properties of saffron (Crocus sativus L.). This high-purity compound is essential for research and development, offering a standardized reference material for quality control and efficacy studies. It is a critical ingredient for manufacturers in the nutraceutical, pharmaceutical, and food & beverage industries seeking to develop products with scientifically-backed benefits.

Application

• Nutraceutical & Dietary Supplements: Used as a key active ingredient in formulations targeting cognitive support, mood enhancement, and antioxidant protection.
• Pharmaceutical Research: Serves as a reference standard and active pharmaceutical ingredient (API) in preclinical and clinical studies for neurological and ophthalmological applications.
• Food & Beverage Coloring: Functions as a natural, water-soluble colorant (E164) in premium food products, confectionery, and beverages.
• Cosmetic & Skincare: Incorporated into serums and creams for its antioxidant properties and potential skin-brightening effects.
• Analytical & Quality Control: Essential as a certified reference material (CRM) for the HPLC assay and authentication of saffron and saffron-based products.
• Biochemical Research: Utilized in cell culture and in vitro studies to investigate mechanisms related to oxidative stress and neuroprotection.
