Greenherb operates a certified processing facility specializing in Hazelnut Extract, a standardized proanthocyanidin-rich botanical ingredient derived from the shells and husks of Corylus avellana through controlled hydroalcoholic extraction and spray drying. Our production system delivers consistent oligomeric proanthocyanidin standardization, verified botanical identity, and batch-level documentation for cardiovascular wellness, antioxidant, and skin beauty supplement formulations.
Corylus avellana produces a familiar edible nut with two commercially distinct fractions. The kernel is valued for its lipid and protein content, rich in monounsaturated fatty acids and vitamin E. The outer shell and husk present a completely different phytochemical profile dominated by condensed tannin proanthocyanidins and flavonoid glycosides. Hazelnut Extract specifically targets this shell fraction. This botanical sourcing decision defines the extract's functional identity as a polyphenol antioxidant ingredient rather than a nutritional nut ingredient.
Hazelnut Powder in the supplement and food market commonly refers to ground kernel material, delivering a fatty, nutty flavor profile with lipid-dominant nutritional content. Hazelnut Extract differs fundamentally. It is derived from the shell fraction through hydroalcoholic extraction, concentrating the polyphenol fraction to a defined HPLC-verified OPC specification. These two ingredients serve entirely different formulation purposes and occupy distinct positions in the ingredient market despite sharing a botanical species name.
Incoming Corylus avellana shell material is authenticated by botanical identity verification and HPLC polyphenol fingerprinting. Total OPC content, moisture, heavy metals, pesticide residues, and microbiological status are screened before processing.
Hazelnut Extract is incorporated into cardiovascular wellness formulations targeting OPC-mediated circulatory comfort. The proanthocyanidin content contributes to products designed to support comfortable blood vessel function, healthy circulation comfort, and a sense of cardiovascular wellbeing during daily routines. The condensed tannin OPC fraction contributes antioxidant protection in both aqueous and lipid-phase vascular environments.
The combined OPC and flavonoid matrix delivers meaningful broad-spectrum antioxidant capacity. This supports product positioning in everyday cellular protection and oxidative stress comfort categories. The polyphenol complexity of hazelnut shell extract contributes multi-pathway antioxidant activity that single-compound antioxidant ingredients cannot replicate.
The OPC and flavonoid content contributes to ingestible beauty and topical skin wellness formulations. Products targeting skin radiance, tone uniformity, and collagen comfort support incorporate hazelnut shell-derived polyphenols as a less commonly used botanical alternative to grape seed or pine bark OPC sources, supporting ingredient differentiation in premium beauty supplement concepts.
Hazelnut manufactory supply for hard capsule, tablet, and powder sachet cardiovascular wellness supplement formats. Standardized OPC content, shell-fraction botanical sourcing documentation, and comprehensive regulatory compliance support finished product positioning in the cardiovascular wellness and antioxidant supplement category.
Multi-ingredient beauty supplement formulations combine Hazelnut Extract with vitamin C, collagen peptides, and complementary skin wellness botanicals. Skin radiance, antioxidant protection, and collagen comfort support are primary positioning concepts in the nutricosmetics supplement category.
Premium supplement brands with sustainability positioning incorporate Hazelnut Extract for its byproduct valorization origin story. Shell-derived polyphenol extraction from nut processing waste streams supports responsible sourcing claims and circular economy ingredient narratives in premium supplement and functional food product marketing.
