Anti-clouding Agents

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.


  1. Dilution - Dilute it into sample oil in ratio 1:5
  2. Heating & Mixing - Heat mix to ~75-80°C and mix properly to ensure all is dissolved into oil (~30mins).
  3. Preheating Oil - Preheat the balance of the oil to ~50°C.
  4. Blending - Add the mixture into preheated sample and mix homogenously (30mins to 1hr depend on qty of the oil and the type of agitation). 
  5. 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.
