Cocoa butter swaps change chocolate texture and aroma
What it found
In lab tests and taste tests, replacing part of the cocoa butter with palm oil or shea butter changed how chocolate released aroma and how its texture and flavour were sensed over time.
Shea butter chocolate felt sandy and held back cocoa flavour when it was left to melt in the mouth.
What they found
Studies in people
Sandy feel with shea
When tasters let the chocolate melt in the mouth, shea butter chocolate was linked to a sandy feel and cocoa flavour became dominant later.
Chewing changed things
The effect of the fat mix depended on whether tasters chewed the chocolate or let it melt. The authors say the tasting method strongly shaped which sensations dominated.
Animal and lab studies
Aroma release slowed
In lab tests, chocolate with shea butter released key aroma compounds more slowly, including 3-methylbutanal. Palm oil and shea butter both changed the release profiles of several aroma compounds.
Other findings
Melting behaviour
Under the conditions tested, the different fat mixes melted in much the same way. The authors found no significant differences in melting parameters.
Flow properties changed
Replacing part of the cocoa butter changed how the melted chocolate flowed. The authors measured this as rheological behaviour.
What the authors conclude
“Overall, fat composition and tasting protocol jointly influenced the temporal trajectory of texture and flavour perception, with implications for the development of economically viable chocolate formulations while preserving sensory quality.”
Also in their conclusions
- They say fat composition and the way chocolate is tasted together shape how texture and flavour are sensed over time.
- They suggest this matters for making cheaper chocolate recipes while keeping the sensory quality.
- They note that using TDS Markov graphs helped them understand the order in which sensations became dominant.
How it was done
Chocolate makers are looking at partly replacing cocoa butter with cheaper fats because of supply limits and rising costs. The authors wanted to see how these swaps affect the way chocolate feels and tastes as it is eaten, not just its basic texture.
They made chocolate samples with cocoa butter partly replaced by palm oil or shea butter, then measured their melting, flow and particle size. They tracked aroma release in lab tests and asked trained tasters to record which sensation was strongest over time while chewing or letting the chocolate melt.
What it can’t tell you
- The taste tests used trained tasters, so the results may not match what ordinary shoppers notice.
- The aroma release was measured in lab tests, which cannot fully copy what happens in a person's mouth.
- This study looked at one set of recipes and conditions, so other fat mixes or amounts might behave differently.
