Introduction

Procyanidin Powder, also known as Proanthocyanidins or OPC, represents one of nature’s most potent bioflavonoids. Characterized by its unique molecular structure, oligomeric proanthocyanidins are widely recognized internationally as highly effective natural antioxidants capable of neutralizing free radicals in the human body.

Sourced primarily from grape seeds and French maritime pine bark, our Procyanidin Powder appears as a reddish-brown fine powder with slight astringency. It offers excellent solubility in water and most organic solvents, making it highly versatile for both dietary supplement and functional food formulations.

Scientific literature has highlighted the ability of proanthocyanidins to support multiple physiological pathways, including antioxidant defense, vascular integrity, and immune modulation. With an antioxidant capacity approximately 50 times that of vitamin E and rapid absorption (peak plasma levels reached within 20 minutes and a metabolic half-life of about 7 hours), Procyanidin Powder has become a preferred ingredient among forward-thinking manufacturers of premium nutraceuticals, cosmeceuticals, and functional beverages.

Production Process

At Botanical Essence, we employ a carefully controlled, multi-step manufacturing process to ensure consistent purity and activity:

  • Raw material selection and cleaning
  • pH-adjusted aqueous extraction
  • Enzymatic hydrolysis
  • Solid-liquid separation
  • Multi-stage refinement and purification
  • Vacuum concentration
  • Precision spray drying
  • Final packaging under GMP conditions

This standardized process guarantees batch-to-batch consistency, excellent solubility, and preserved bioactivity of the oligomeric proanthocyanidins.

Quality Standards & Specification

Our Procyanidin Powder is tested according to validated colorimetric methods (vanillin-HCl assay) that specifically measure total proanthocyanidins content. The method is suitable for various plant matrices including grape seed and pine bark extracts.
