Introduction
Crystallization in palm olein during transportation, storage, and shelf display in cooler climates causes cloudiness, which is perceived by consumers as a sign of poor quality. Preventing crystallization is crucial to maintaining the oil's clarity and ensuring consumer acceptance.
Why does Palm Olein Becomes Cloudy?
- Happens when stored at cooler temperatures
- Tiny crystals formed due to low temperature
- Crystals scatter light and make oil looks hazy
- Consumers prefer clear oil by control crystallization
- Poor crystallization process during fractionation
How to Solve Cloudiness in Palm Olein ?
- A more practical solution is using an anti-clouding agent with optimum dosage vs. iodine value.
- GSI anti-clouding agent is made from polyglycerol and fatty acids. It works by changing the way fat crystals form, keeping the oil clear and stable.
- GSI anti-clouding agent is already used in many food products to improve stability and prevent crystallization.
How GSI Anti-Clouding Agent Works :
- Palm olein has fat molecules (POP, PLP, POS, PSL) that form crystals to make oil looks cloudy.
- GSI anti-clouding agent retard crystals from growing bigger.
- This keeps the oil clear for longer.
- GSI anti-clouding agent works as a crystallizer to improve palm olein yield at a dosage of 0.5%.
ADDITION OF GSI Anti-Clouding Agent
The process of adding our anti-clouding agent to sample oil involves a few key steps to ensure proper dissolution and homogenization.
- Dilution - Dilute it into sample oil in ratio 1:5
- Heating & Mixing - Heat mix to ~75-80°C and mix properly to ensure all is dissolved into oil (~30mins).
- Preheating Oil - Preheat the balance of the oil to ~50°C.
- Blending - Add the mixture into preheated sample and mix homogenously (30mins to 1hr depend on qty of the oil and the type of agitation).
- Cooling - Cool down to 35°C to 40°C then followed by packing at the selected temperatures.
Note: The correct use of GSI Anti-Clouding Agent is very important; to avoid overdosing, please keep it within 0.05–0.30% of the total oil, as excess amounts may have the reverse effect.
