Pure Glucoraphanin

Pure Glucoraphanin Powder – Standardized Broccoli Seed Extract for Advanced Nutraceutical Applications 

Pharmaceutical Grade Pure Glucoraphanin from Broccoli Seeds (Brassica oleracea var. italica) Standardised Active Content ≥13% (HPLC) from Hefei Fushan Yuansheng Biotechnology. Our proprietary aqueous extraction and proprietary pre-treatment process eliminate risk impurities such as allyl isothiocyanate and reduce erucic acid to below regulatory thresholds, securing safety and long-term stability.

With 13 years of Nrf2 research, 30+ issued patents and 10+ human clinical studies, our EXTRABROC® ingredient is held to the highest quality control. We are a science-backed and trusted solutions provider for worldwide nutraceutical & functional food producers with a consistent production capacity of 50 tonnes per year & FDA, GMP, ISO22000, HACCP and HALAL certifications.

What Is Pure Glucoraphanin and Why Does Purity Matter?

Our product (4-methylsulfinylbutyl glucosinolate, C12H23NO10S3) is the stable, naturally occurring precursor of sulforaphane, a powerful activator of the Nrf2 pathway. The pure-grade substance solves key industrial problems that crude broccoli extracts cannot: it removes off-flavor chemicals such glucobrassicin, reduces strong odours and removes secondary metabolites that impact formulation stability.

Our extract retains its bioactive integrity across gastric transit and transforms predictably to sulforaphane in the presence of myrosinase enzyme or healthy gut bacteria.  This means your formulations provide constant therapeutic level doses without having to eat large amounts of raw veggies.

Technical Specifications

Key Advantages That Solve Your Formulation Challenges

Ultra-Stable Shelf Life

Our Pure Glucoraphanin is the only extract in the world that is stable for 2 years at room temperature without refrigeration or special treatment. This saves you on cold-chain logistics expenses and makes your supply chain management simpler.

Traceability & Quality Control

Complete documentation from seed to completed product on every batch. Our patented quality management system controls growing conditions, extraction parameters and final product testing to ensure batch-to-batch uniformity.

Clinically Proven Effectiveness

Our ingredient is backed by 10+ human clinical trials and real-world research to provide you the science you need to support your substantiation claims, regulatory filings and marketing credibility.

Configurable Content Tiers

We provide a quick-response approach (3-7 days) for active-ingredient content modification. We can tailor to your demands, from lower concentrations for drinks, to high strength grades for capsules.

Versatile Applications Across Multiple Product Categories

Advanced Dietary Supplements

Great for Nrf2 activating pills and tablets. We are compatible with dual-chamber administration methods that combine Pure Glucoraphanin with exogenous myrosinase to maximize sulforaphane absorption and avoid gut microbiota fluctuation.

Functional Foods and Drinks

This ingredient is heat resistant and water soluble and is especially effective in RTD drinks, quick nutritional powders, energy bars and fortified superfood blends. It survives pasteurization intact structurally, unlike direct sulforaphane, without giving sulfurous off-notes.

Sports Nutrition & Recovery Products

Supports cellular antioxidant defense systems important for recuperation after exercise. It has a mild flavor profile that makes it easy to add into protein powders and hydration formulas.

Medical Grade Nutrition & Nutricosmetics

It is used in therapeutic nutrition for metabolic support and in detoxification formulas. In beauty-from-within oral supplements, it is an internal UV-defense agent targeting oxidative stress reduction with prolonged shelf-stability.

Comprehensive Quality Control You Can Trust

Robust quality control of product by High-Performance Liquid Chromatography (HPLC-DAD) for verification of precise glucosinolate profiles. The inspection procedure consists of:

Purity Assay: Validates the glucoraphanin content to be in line with the label claims.

Heavy Metal Screening ICP-MS testing for Lead (<1.0ppm), Arsenic (<0.5ppm), Cadmium and Mercury.

Contaminant Profiling: Erucic acid testing (generally <2%) and glucobrassicin monitoring for safety and sensory quality.

Microbiological Control: Strict limitations on Total Plate Count, Yeast/Mold, zero tolerance on E. coli and Salmonella.

Residual Solvent Analysis – GC-MS testing to ensure that ethanol or water extraction residues are within USP/EP limits.

All of these criteria are documented on each Certificate of Analysis giving complete transparency for your regulatory filings and quality checks.
