How to Store Palm Oil for A Long Time?
Palm oil is one of the most widely consumed vegetable oils globally, extensively used in food processing, catering, and industrial applications. However, long-term storage of palm oil faces numerous challenges, including oxidation, rancidity, and quality degradation. This article, drawing on the professional expertise of Henan Huatai Cereals and Oils Machinery Co., Ltd., will systematically introduce the scientific methods and key technologies for the long-term storage of palm oil.
Main Challenges in Palm Oil Storage
Palm oil is susceptible to the following factors during storage:
1) Oxidative deterioration: Contact with oxygen in the air leads to oil oxidation and the development of rancid odors.
2) Moisture influence: High moisture content promotes hydrolysis reactions, increasing the free fatty acid content.
3) Temperature fluctuations: High temperatures accelerate oxidation, while low temperatures may lead to palm oil fractionation and crystallization.
4) Light exposure: Ultraviolet and visible light can trigger photo-oxidation reactions.
5) Metal contamination: Metal ions such as copper and iron are potent oxidation catalysts.

2) Quality Tracking System:
Regularly test indicators such as acid value and peroxide value
Establish a complete quality archive for traceable management
Best Practices for Long-Term Palm Oil Storage
Combining Huatai Oil Machinery’s professional advice, long-term palm oil storage should follow the following principles:
1) Storage Environment Control
Temperature: Maintain at 25-30℃, avoiding high temperatures and drastic fluctuations
Light: Storage tanks should be placed in a dark environment or use light-blocking protection
Humidity: Control warehouse humidity below 60%
2) Storage Container Management
Regularly check the airtightness of the storage tanks
Thoroughly clean and dry new tanks before use
Avoid mixing different batches of oil
3) Regular Inspection and Maintenance
Test acid value and peroxide value once a month
Check the operating status of the nitrogen protection system
Record storage time and follow the “first-in, first-out” principle
4) Transportation and Transfer Precautions
Use dedicated pipelines and pumping equipment.
Avoid vigorous stirring and air mixing.
The conveying system provided by Huatai minimizes oxygen contact.
