Avocado Soybean Unsaponifiables (ASU) Powder / Paste (Golden 1:2 Ratio | Total Phytosterols ≥35% & ≥50%)
Premium Chondrocyte Protective Ingredient · High-Purity Molecular Distillation · Excellent Batch Stability for Hard Capsules & Tablets
R&D Insights: Mastery of Extraction & Ratio Integrity in Joint Care
Technical notes from our natural lipid extraction & plant sterol research team.
Avocado Soybean Unsaponifiables (ASU) represent one of the most clinically supported natural solutions for preserving joint cartilage and inhibiting pro-inflammatory cytokines like IL-1β. However, manufacturing high-grade ASU presents significant technical challenges. Conventional solvent extraction techniques frequently leave toxic chemical residues and suffer from batch-to-batch ratio fluctuations, leading to compliance rejections in strictly regulated overseas markets.
Our facility utilizes advanced low-temperature saponification combined with multi-stage molecular distillation. This physical purification process isolates the active unsaponifiable fractions-specifically β-sitosterol, stigmasterol, and campesterol-without harsh chemical solvents. We guarantee a strict, immutable 1:2 ratio of avocado oil to soybean oil unsaponifiables, providing brand owners with a consistent, premium bulk raw material engineered for capsules, softgels, and oral tablets.

Frequently Asked Questions (FAQ)
Q1: What is the significance of the 1:2 Avocado to Soy unsaponifiable ratio?
A: Clinical studies evaluating joint cartilage restoration demonstrate that combining 1 part avocado unsaponifiables with 2 parts soybean unsaponifiables yields maximum biological synergy. This specific ratio optimizes collagen synthesis in chondrocytes and reduces cartilage degradation far more effectively than either ingredient alone.
Q2: What is the difference between your ASU powder grade and ASU paste grade?
A: Our paste grade is the direct concentrated unsaponifiable lipid extract, ideal for softgel encapsulation or oil-based suspensions. Our powder grade utilizes non-GMO food carriers to convert the lipid extract into a free-flowing granular powder optimized for hard gelatin/vegetable capsules and direct tablet compression.
Q3: How do you ensure solvent residues are kept below strict international limits?
A: We employ multi-stage physical molecular distillation under high vacuum. This physical separation technology strips off low-boiling point impurities and residual extraction solvents without subjecting the heat-sensitive phytosterols to damaging thermal conditions, fully satisfying USP and European Pharmacopoeia safety standards.
Q4: Does this material carry allergen warnings due to the soy component?
A: Unsaponifiables consist of plant sterols and lipid fractions isolated from soybean oil, meaning soy proteins are removed during processing. However, because it originates from soy, we provide full allergen documentation to help you comply with your regional labeling requirements.
Q5: How can our R&D or procurement team request trial evaluation samples?
A: Simply complete the inquiry form below or reach out to our sales team. We will dispatch a 100g sample kit along with full batch COA, GC chromatograms, and technical data sheets within 24–48 hours.
