Cold Press Extraction Services in Thailand

• ✓ 100% Mechanical Extraction: Uses pure mechanical pressure (Mechanical Pressing) to separate oil from seeds, nuts, or fruits without the use of any chemicals or synthetic solvents.

• ✓ Strict Temperature Control (< 49°C): Operates under strict low-temperature conditions to prevent the thermal degradation of delicate bioactive compounds and vital plant nutrients.

• ✓ Preserves Pure Natural Integrity: Locks in the original color, aroma, flavor profile, and native unsaturated fatty acids while actively preventing lipid oxidation.

• ✓ 100% Safe and Residue-Free: Completely avoids thermal scorching or chemical extraction (such as the Hexane method), yielding a 100% pure, unrefined, premium-grade natural oil.

Ideal Target Compounds for Cold Press Extraction

🧴 Premium Cosmetics & Skincare

• Vitamin C & Retinoic Acid (Rosehip Seed): Boosts collagen synthesis and targets fine lines. [Highly heat-sensitive: thermal exposure destroys Vitamin C instantly; cold pressing is mandatory.]

• Omega-3 & 6 Ratio 1:3 (Hemp Seed): Calms skin inflammation and deeply nourishes the scalp. Cold pressed to preserve the delicate, native "golden ratio" of fatty acids.

• Omega-7 & Beta-Carotene (Sea Buckthorn): Formulated for cellular regeneration, eczema, and intense dry-skin repair. Cold pressing prevents the rapid oxidation of carotenoids.

• Oleic Acid >72% (Marula): Creates a lightweight, ultra-luxurious, fast-absorbing face oil. Cold pressing yields a pristine lipid profile entirely free from rancid notes.

💊 Nutraceuticals & Dietary Supplements

• ALA Omega-3 >55% (Flaxseed / Perilla Seed): Essential for brain health and cardiovascular support; a premier plant-based Omega for vegan products. [Prone to converting into unhealthy trans-fats under heat; process temperatures must be strictly kept below 49°C.]

• Thymoquinone (Black Cumin Seed): Delivers powerful immune support and broad-spectrum anti-inflammatory properties. [A highly volatile compound that breaks down rapidly if temperatures exceed 60°C.]

• Phytosterols & Zinc (Pumpkin Seed): Tailored for prostate health and androgenic hair loss supplements. Actives retain peak bio-efficiency when extracted mechanically without chemicals.

🍽️ Gourmet Foods & Specialty Oils

• Sesamin & Sesamol (Sesame Oil): Packed with potent antioxidants and a rich, authentic aroma. Eliminates the need for chemical refining, allowing a "Cold Pressed" label claim that drives retail margins 3–5× higher than standard oils.

• Behenic & Oleic Acid (Moringa Seed): Natural anti-microbial and anti-fungal properties. Cold pressing maintains the native stability of these fatty acids, rendering the oil highly resistant to rancidity without adding synthetic preservatives.

FAQ: Frequently Asked Questions about Cold Press Extraction

How does Cold Press differ from conventional Expeller Pressing?

While both methods rely purely on mechanical force, a standard Expeller Press does not utilize temperature controls. Friction within the screw mechanism routinely drives internal temperatures up to 60–99°C, which rapidly degrades heat-sensitive compounds like Vitamin C, ALA Omega-3, and delicate terpenes.

MSTEM LAB’s Cold Press technology integrates continuous electronic thermal monitoring to guarantee that temperatures never exceed 49°C at any point, ensuring an oil with far superior nutritional density that fully complies with authentic international "Cold Pressed" standards.

Is the oil yield lower with Cold Pressing? Is it commercially viable?

Cold pressing typically generates a 15–30% lower yield compared to standard Hexane Solvent Extraction. However, for premium-tier products, this margin difference is highly profitable because:

1. Premium Valuation: Cold pressed oils command prices 2–5× higher in the premium cosmetics and nutraceutical sectors.

2. Lower Post-Processing Costs: It completely eliminates expenses associated with vacuum solvent removal and mandatory residual chemical testing.

3. Market Differentiation: The "Cold Pressed" clean-label claim creates immediate brand differentiation over mass-market commodity oils. (Note: For cheap commodity oils where volume and low cost are the sole factors, hexane extraction remains more cost-efficient).

Can local Thai and regional ASEAN seeds be cold-pressed?

Absolutely. MSTEM LAB has extensive R&D experience processing botanical raw materials native to Thailand and Southeast Asia.

High-performance regional crops include black and white Sesame, Moringa seed, Roselle seed, Pumpkin seed, Perilla (Shiso), and Pomegranate seed—alongside many other oil-dense botanicals. If you have a specific regional crop, contact us; our engineering team will run a free feasibility study and oil-content profile analysis for you.

What is the shelf life of unrefined Cold Pressed oil?

Unrefined cold-pressed oils generally have a shelf life of 6 to 18 months, depending on the native fatty acid structure and storage practices. Oils with high polyunsaturated fatty acid (PUFA) profiles—such as flaxseed or hemp seed—are naturally more prone to oxidation.

To maximize stability, we recommend using dark amber glass or lightproof containers, coupled with a nitrogen gas flush at bottling. MSTEM LAB also provides custom blending services with natural antioxidants (such as non-GMO Vitamin E or Rosemary extract) tailored specifically to your oil's molecular matrix.
