Why Extraction Technology Matters for Marine Oils

The way marine oils are extracted plays a major role in determining their purity, stability, and nutritional integrity.

The Challenge of Processing Marine Oils

Marine organisms such as abalone contain complex lipid structures that are naturally delicate. Many of these compounds can be sensitive to heat, oxidation, and harsh chemical processing.

Traditional oil extraction methods often rely on high temperatures or industrial solvents to separate oils from raw materials. While these approaches can be efficient, they may alter or degrade some of the naturally occurring lipid compounds found in marine ingredients.

For premium marine products, preserving the integrity of these natural compounds is an important consideration.

Why CO₂ Extraction Is Different

Supercritical CO₂ extraction is a modern processing technology increasingly used for high-value natural ingredients.

In this method, carbon dioxide is placed under controlled temperature and pressure until it reaches a “supercritical” state, where it behaves both like a gas and a liquid. In this form, CO₂ can gently separate oils from raw materials without the need for high heat or chemical solvents.

Once the extraction is complete, the pressure is released and the CO₂ simply evaporates, leaving behind the extracted oil.

This method is valued because it is:

• Low-temperature, helping reduce heat damage to sensitive compounds

• Solvent-free, leaving no chemical residues

• Precise, allowing careful extraction of delicate marine lipids

Protecting the Natural Lipid Profile

Marine organisms develop their lipid composition over many years within complex ocean ecosystems. These lipid structures are one of the reasons marine foods have attracted scientific interest in recent years.

Using a gentle extraction method helps maintain this natural lipid diversity as much as possible during processing.

From Ocean to Oil

Oceanz Vital uses CO₂ extraction technology to carefully process wild New Zealand abalone.

This approach helps preserve the ingredient in a clean, stable form while maintaining the naturally occurring marine lipid profile that develops in the ocean.

In this way, a rare traditional marine food can be captured in a modern, carefully processed oil.
