Glucoraphanin
Glucoraphanin is the stable glucosinolate precursor of sulforaphane, extracted from broccoli seeds (Brassica oleracea var. italica), standardized to 10%, 13%, 20% and 50% by HPLC. It is light yellow fine powder, water soluble, produced by water extraction and spray drying.
Dietary supplement grade, far more stable than direct sulforaphane oil; when co-ingested with myrosinase, it converts into sulforaphane in vivo to support Nrf2 antioxidant and cellular detoxification pathways. Compliant with ISO22000, HACCP, GMP, HALAL & KOSHER, each batch with full HPLC COA report. Myrosinase pre-blend service available.

Core Benefits & Functional Mechanism
Glucoraphanin is a glucosinolate stored in broccoli seeds. When ingested with the enzyme myrosinase (or gut microflora), it hydrolyzes into sulforaphane, which activates the Nrf2 pathway and supports the body’s endogenous antioxidant defense and cellular detoxification systems.
Compared with unstable sulforaphane oil, glucoraphanin powder offers far better shelf stability and formulation convenience for hard capsules, tablets and functional beverages. Multiple HPLC standardized specifications allow flexible formula design.
- Stable precursor form, much better shelf life than sulforaphane oil
- 10%–50% HPLC standardized content for flexible formula design
- Water soluble light yellow powder, easy for capsules and tablets
- Co-blendable with myrosinase to promote in-vivo conversion
- Triggers Nrf2 antioxidant response and phase II detox enzymes
- Non-GMO, clean label botanical ingredient
Glucoraphanin Production Process
Complete Manufacturing Steps
- Broccoli seed selection: clean, sort and inspect Brassica oleracea seeds
- Water extraction of glucosinolate fraction under controlled temperature
- Filtration and vacuum concentration
- Standardization adjustment to target 10%/13%/20%/50% glucoraphanin
- Spray drying into light yellow fine powder
- Sieving and blending for batch homogeneity
- Sealed moisture-proof packaging with unique batch trace-code
The whole production is operated in GMP food-grade workshop. Every batch is tested by HPLC for glucoraphanin content, heavy metal and microbiological inspection. Low-temperature water extraction and spray drying preserve the stable glucosinolate structure.
