Blending Palm Oils Enhances Thermal Stability and Reduces Degradation

Partial replacement of palm olein with palm kernel oil improves the thermal stability of cooking oils, leading to reduced degradation.

European Journal of Agriculture and Food Sciences · 2020

Key Findings

01Blending palm olein with palm kernel oil generally improved the stability parameters compared to using either oil alone.
02Increasing the concentration of palm kernel oil (saturated fatty acids) led to increased stability against oxidation and thermal stress.
03Higher palm kernel oil content resulted in a reduction of free fatty acids (FFA).

Application

Design takeaway

When designing cooking oil formulations, consider blending palm olein with palm kernel oil to enhance thermal stability and reduce degradation.

How to apply

When developing or reformulating cooking oils for high-heat applications, experiment with different ratios of palm olein and palm kernel oil, and test their stability using methods that simulate expected usage conditions.

Project actions

01When investigating material properties, consider how blending different components can affect performance.
02Document the precise ratios and processing conditions used in any material formulation.

Method & Evidence

AimTo investigate the effect of blending palm olein with palm kernel oil on the chemical stability of the oils when subjected to elevated temperatures.

MethodExperimental analysis using photometric technology and standard physicochemical tests.

ProcedureBlends of palm olein (POL) and palm kernel oil (PKO) were formulated in various ratios (100:0, 80:20, 60:40 for both POL:PKO and PKO:POL). Samples were heated at 100°C, 150°C, and 200°C for 20, 40, and 60 minutes. Physicochemical properties such as free fatty acid, peroxide value, iodine value, anisidine value, and totox value were evaluated before and after heating.

ContextFood science, edible oil formulation, culinary applications.

Variables

IV["Ratio of palm olein to palm kernel oil","Temperature of heating","Duration of heating"]

DV["Free fatty acid (FFA) value","Peroxide value","Iodine value","Anisidine value","Totox value","Viscosity","Colour"]

CV["Type of oils used (palm olein, palm kernel oil)","Photometric technology used for measurement"]

Strengths & Limitations

Strengths

+Utilized a fast and reliable photometric technology for efficient analysis.
+Investigated a range of blending ratios and thermal stress conditions.

Limitations

The study used specific laboratory equipment; replicating these exact conditions might be challenging. The long-term effects of these blends on food flavour were not assessed.

Reliability & validity

The use of standard physicochemical tests and photometric technology lends reliability to the measurements. Validity is supported by comparing blend results to individual oil results under controlled thermal stress.

Think critically

How might the sensory properties (taste, smell) of these blended oils be affected, and how would that impact their suitability for different culinary applications?

Design Principles

"Strategic blending of oils with different saturation levels can optimize performance under thermal stress."

This research offers practical insights for the food industry and product developers in formulating more stable cooking oils. Understanding how different oil blends behave under heat can lead to improved product longevity, reduced waste, and potentially more cost-effective formulations.

What This Means for Your Design

Mixing different types of palm oil can make cooking oil last longer and perform better when heated.

Paragraph starter

Research indicates that blending palm olein with palm kernel oil can significantly improve thermal stability, a key parameter for cooking oils. For instance, studies have shown that increasing the proportion of saturated fatty acids from palm kernel oil enhances resistance to oxidation and thermal degradation, leading to reduced free fatty acid formation (Imoisi et al., 2020). This principle can be applied to design projects requiring robust edible oil formulations.
