Solvent Extraction Services in Thailand

• ✓ Target-Driven Solvents: Utilizes specialized liquid solvents (such as Ethanol or Pure Water) to efficiently penetrate and draw out active bio-compounds from herbal and biological raw materials.

• ✓ Maximum Flexibility: Allows precise selection and modification of solvents to perfectly match the polarity (water-loving vs. oil-loving nature) of your target compounds.

• ✓ Broadest Extraction Spectrum: Captures a comprehensive profile of active ingredients in a single run, covering both:

  • Polar Compounds (Water/Alcohol Soluble): e.g., Polyphenols, Alkaloids.

  • Non-Polar Compounds (Lipid Soluble): e.g., Essential Oils, Plant Waxes.

• ✓ Commercial-Scale Viability: Accommodates a vast range of substrates and applications. It is the most cost-efficient and high-yield choice for large-scale production, significantly lowering your cost-per-kilogram.

• ✓ Advanced Vacuum Evaporation: Utilizes low-temperature vacuum systems to swiftly strip away solvents, preserving heat-sensitive compounds while driving residual chemicals down to safe, standardized limits.

• Lutein (Marigold Flowers): Golden-yellow pigments for eye-health beverages, processed via mass-scale, low-cost parameters.

FAQ: Frequently Asked Questions about Solvent Extraction

How does Solvent Extraction differ from Supercritical CO₂ Extraction?

Solvent Extraction offers significantly higher flexibility and a wider extraction spectrum, successfully capturing both polar and non-polar compounds. It is more cost-efficient and easier to scale up.

The main operational difference is that Solvent Extraction requires a solvent-removal phase and a mandatory GC-MS residual test for every batch. While Supercritical CO₂ leaves zero residue and is ideal for pharma injectables and ultra-premium products, Solvent Extraction is undeniably the most cost-efficient method for standard-grade extracts, polyphenols, herbal blends, and large-volume commercial production.

Are the solvents used safe for food-grade products and supplements?

Yes, this depends entirely on the solvent you select. Our Food-grade Ethanol and Pure Water offer the highest level of safety and are fully recognized by the US FDA, EU EFSA, and the Thai FDA (classified under ICH Q3C Class 3 with a safe limit of up to 5,000 ppm). For Hexane, the extract undergoes rigorous vacuum evaporation to ensure that any residual levels drop well below the strict legal threshold of ≤ 290 ppm before delivery.

Is Solvent Extraction suitable for Thai traditional herbs?

It is an exceptional match. Ethanol and Ethanol-Water blends have been the gold standard for Thai herbs for decades. This method works perfectly with Turmeric (curcuminoids), Ginger (gingerols), Andrographis paniculata (andrographolide), Black Galingale (flavonoids), Tinospora crispa (alkaloids), and Kaffir Lime leaves (limonene). Our team has extensive, direct R&D experience processing local Thai raw materials.

If I want the final extract in a powder form, what are the next steps?

After the primary Solvent Extraction and solvent-removal phases, we obtain a liquid extract or a concentrated paste. To convert this into a dry powder, we route the material through either Spray Drying (for heat-stable compounds) or Freeze Drying / Lyophilization (for heat-sensitive compounds) to preserve the delicate active molecules.
