🐟 Understanding the Color and Sediment in Crude Fish Oil

🐟 Understanding the Color and Sediment in Crude Fish Oil

🌊 Introduction

Crude Fish Oil (CFO) is one of nature’s most valuable yet complex oils. Extracted from fish by-products, it contains high levels of omega fatty acids, proteins, and natural pigments that make it essential for feed, soap, and biofuel industries.

However, many first-time buyers often ask:

“Why is crude fish oil not clear like refined oil?”

At Rich Moon, we believe in transparency — literally and figuratively — so here’s everything you need to know about the color, texture, and sediment that make crude fish oil unique.

🎨 1. Why Crude Fish Oil Appears Yellow or Brown

The color of crude fish oil can range from light golden yellow to deep amber brown depending on:

• 🐠 Type of fish species used (anchovy, mackerel, sardine, tuna, etc.)

• 🔥 Processing temperature — higher heat darkens the oil

• ⏱️ Oxidation during storage — prolonged exposure to air causes slight browning

• 💧 Moisture and protein traces left from extraction

🎯 Fun fact:
Rich Moon’s crude fish oil typically maintains a natural golden hue because we carefully control drying temperature and oxidation time during processing.

⚗️ 2. Understanding Sediment Formation

The sediment or cloudiness you see at the bottom of crude fish oil is not contamination — it’s a normal part of unrefined oil.

These particles usually consist of:

• Protein residues

• Waxes and phospholipids

• Microscopic bone or tissue traces

• Small quantities of free fatty acids

🌡️ When crude oil cools, these components solidify, causing a cloudy layer or creamy base.
When gently warmed (around 30°C–35°C), the oil usually becomes clearer and more fluid again.

🧪 Rich Moon Note: This natural sediment proves that the oil is unrefined and still rich in its original nutrients and fatty acids.

🧊 4. How to Maintain Quality of Crude Fish Oil

Even with sediment, high-quality crude oil can stay stable if stored correctly.

Rich Moon recommends:

• 🧯 Store below 35°C in shaded, dry environments

• 🧴 Use sealed drums or IBC tanks

• 🧪 Check FFA and Peroxide Value regularly

• 🚢 Ship in nitrogen-flushed containers for long-distance exports

This ensures minimal oxidation and keeps the oil usable across all industrial applications.

🌿 5. Rich Moon’s Promise of Purity

At Rich Moon, we focus on consistency, sustainability, and honesty in every drop.
Each batch of crude fish oil undergoes strict inspection before export — ensuring clients receive oil that is:

• Naturally extracted

• Fully traceable

• Professionally stored

• Tested for moisture, FFA, and color index
