Cold-press operation is a traditional yet innovative oil extraction technique that preserves the natural nutrients, flavour, and aroma of oils. Unlike conventional methods that use heat and chemicals, cold pressing involves mechanical extraction at low temperatures, making it a preferred choice for health-conscious consumers. Food experts contribute significantly to optimizing this technique, ensuring efficiency, quality, and market competitiveness.
Introduction
Cold-press oil extraction is gaining traction in the food industry due to its ability to produce oils that retain natural antioxidants, vitamins, and essential fatty acids. The absence of heat or chemical solvents during extraction ensures minimal degradation, resulting in a superior quality product. This method is particularly popular for extracting oils from seeds, nuts, and fruits, such as olive, coconut, and flaxseed.
The Process of Cold-Press Operation
Cold pressing involves crushing seeds or nuts under high pressure in a temperature-controlled environment. The extracted oil is then filtered and packaged without further refining, preserving its natural properties. This eco-friendly process aligns with the growing demand for clean-label and sustainable food products.
Key Points of the Cold-Press Process
- Seed Preparation
- Cleaning and drying seeds to ensure purity and prevent contamination.
- Removing outer shells or husks when necessary to improve yield.
- Mechanical Extraction
- Using hydraulic or screw presses to extract oil under controlled low temperatures (below 50°C).
- Avoiding heat application to maintain nutrient integrity and flavour.
- Filtration
- Removing impurities through natural sedimentation or fine filtration methods.
- Ensuring oil clarity while retaining nutrients.
- Packaging and Storage
- Using dark or airtight containers to protect oils from light and oxidation.
- Maintaining a stable storage environment to preserve quality.
