KEYO - Enzymatic Fresh Saccharina japonica Extract
Pure Seaweed, natural balanced
Pure Power, all effects come from seaweed alone
KEYO™ Enzymatic Seaweed Extract – Fresh Saccharina japonica
KEYO™ Enzymatic Saccharina japonica (formerly Laminaria japonica) Extract is made from fresh kelp — not dried flakes — and processed via the same proprietary 100% enzymatic hydrolysis technology as the rest of the KEYO™ series. Harvested and processed within 24 hours, the fresh raw material retains significantly higher levels of polyphenols, phytohormones, and polysaccharides compared to dried-source extracts. The result is a balanced, broad-spectrum biostimulant with the richest overall bioactive profile in the KEYO™ range.
- Made from fresh Saccharina japonica — never dried
- From harvest to finished product in under 24 hours
- Zero acid or alkali used in production
- Enzyme-only process maximally preserves native bioactives
- Highest polyphenol content among all KEYO™ grades
- Balanced spectrum — ideal as a versatile, all-purpose biostimulant
Identical 100% Enzymatic Process – Fresh Raw Material
- Harvest fresh Saccharina japonica and process within 24 hours
- Grind fresh seaweed directly into a paste (no pre-drying step)
- Add cellulose, fucoidanase, and alginate lyase into the reactor
- Hydrolyze at 40–50°C for 12 hours for complete enzymatic conversion
Technology Comparison: Enzymatic vs. Chemical vs. Cold-Press
| Feature | Full Enzymatic Hydrolysis (KEYO™) | Chemical Extraction | Cold-Press Method |
|---|---|---|---|
| Principle | Precise enzymatic action gently breaks down cell walls | Harsh chemicals and high heat degrade raw material | Physical pressure breaks cells |
| Bioactivity | Optimal – preserves natural growth regulators & polysaccharides | Low – severe damage to active components | High – avoids thermal damage |
| Key Advantage | Superior bioactivity & purity; eco-friendly | Low cost; fast production | Good balance; no chemical residues |
| Result | Rich in small-molecule oligosaccharides; superior absorption efficiency | Incomplete active spectrum; weaker effect | Large molecules; lower extraction concentration |

Why Fresh Saccharina japonica? Maximum Bioactive Retention
- Fresh, Not Dried: No oxidative loss during drying — full native bioactive spectrum preserved
- Rich in Polyphenols: Highest antioxidant capacity among all KEYO™ grades
- 24-Hour Processing Window: From harvest to finished product in under 24 hours — minimal degradation
- Balanced Hormone Profile: Naturally occurring auxins, cytokinins, and betaines in optimal ratios
- More Bioactives Than Dried Source: Fresh processing retains compounds lost in conventional dried-seaweed extracts
KEYO™ Fresh Saccharina japonica – Primary Agronomic Benefits
- Balanced Bioactives: Polyphenols + hormones + polysaccharides in one product
- Enhance Antioxidant Capacity: Polyphenol-rich formula strengthens plant defense systems
- Promote Overall Vigor: Balanced hormone spectrum supports full-cycle crop health
- Improve Stress Resilience: Fresh-source antioxidants help crops cope with abiotic stress
- Compatible with AOS & COS: Ideal for multi-active biostimulant formulations
