Our Vegetable Oil Byproduct Deodorizer Distillate (DD) is a high-value raw material derived from edible oil refining. Rich in natural antioxidants (e.g., tocopherols, sterols) and free fatty acids, it serves as a sustainable feedstock for bio-based products, including biodiesel, cosmetics, and specialty chemicals. Sourced from soybean, palm, and rapeseed oil refineries, DD undergoes rigorous purification to remove odorants and volatile impurities, ensuring consistent quality for downstream applications.
Nutrient-Rich Composition
Contains 8–15% tocopherols (Vitamin E, α/β/γ/δ isomers) and 5–10% sterols (β-sitosterol, campesterol), with a total unsaponifiable matter content of 15–25%. These bioactive compounds offer antioxidant, anti-inflammatory, and emollient properties, ideal for nutraceutical and cosmetic formulations.
Free fatty acid (FFA) content ≥60% (predominantly oleic, linoleic acids), meeting the EN 14214 standard for biodiesel feedstock when pretreated. The FFA profile allows efficient conversion via acid-catalyzed transesterification.
Sustainable Processing
Extracted via short-path molecular distillation (operating pressure <1 mbar), preserving heat-sensitive compounds with a recovery rate >95%. This green technology reduces energy consumption by 40% compared to conventional vacuum distillation.
Circular economy approach: Utilizes 100% of deodorizer waste streams, converting what was once a disposal liability into a valuable raw material, with a waste reduction factor of 0.8 tons CO2e/ton DD produced.
High Purity Grades
Tocopherol concentrates up to 70% purity achievable through supercritical CO2 extraction (300 bar, 60°C), yielding products compliant with USP Vitamin E standards. Heavy metal content <1 ppm, arsenic <0.1 ppm, meeting pharmaceutical-grade requirements.
Free of residual pesticides (detection limit <0.01 ppm) and PAHs (polycyclic aromatic hydrocarbons), ensured by rigorous feedstock screening and multi-stage filtration.
Versatile Applications
Biodiesel: FFA conversion efficiency >98% using a two-step process (esterification + transesterification), producing biodiesel with a cetane number ≥50 (EN 14214).
Cosmetics: Emollients in anti-aging creams (improving skin elasticity), sunscreen formulations (UV protection via tocopherols), and hair conditioners (moisture retention).
Food: Natural antioxidants for edible oil stabilization (0.01–0.02% dosage), extending shelf life by 20% compared to synthetic BHA/BHT.
Industries:
Biodiesel: Feedstock for large-scale production facilities (50,000–100,000 tons/year), especially in regions with high vegetable oil consumption (e.g., Indonesia, Brazil).
Cosmetics: Raw material for luxury skincare brands, used in serums (1–5% tocopherol concentrate) and lip balms (emollient base).
Pharmaceuticals: Intermediate for Vitamin E supplements, with tocopherol concentrates used in soft gelatin capsules (400–1,000 IU per dose).
Processes:
Transesterification: Catalyzed by sulfuric acid (0.5–1.0%) for FFA reduction, followed by sodium methoxide (1.0–1.5%) for triglyceride conversion.
Molecular Distillation: Separates DD into fractions: light (volatile odorants), middle (tocopherols/sterols), and heavy (residual glycerides).
Saponification: Produces soap noodles and surfactants, with a conversion yield of 95–98% using NaOH (1:1.2 molar ratio).
Q: What is the source of DD?
A: Primarily from soybean oil refining (60% of global supply), followed by palm (25%) and rapeseed (15%). Sourced from certified non-GMO suppliers for food-grade applications.
Q: How is tocopherol extracted from DD?
A: Through a three-step process: solvent extraction (hexane), winterization to remove waxes, and molecular distillation to isolate tocopherols. Purity can be further enhanced via chromatography for pharmaceutical use.
Q: Can DD be used directly in biodiesel?
A: Yes, after pretreatment to reduce FFA content below 5% (via esterification). Direct use without pretreatment may cause catalyst poisoning in transesterification reactors.
Q: What is the shelf life of DD?
A: 12 months when stored in airtight stainless steel containers under nitrogen at ≤25°C. Oxidation can be delayed by adding 0.05% BHT as a preservative.
Q: What is the typical tocopherol composition?
A: Soybean DD contains 60–70% γ-tocopherol, 20–25% δ-tocopherol, and 5–10% α/β-isomers, offering broad-spectrum antioxidant activity.
