ACS published a paper about how to make a reduced-fat chocolate by scientists

SHAFAQNA- Chocolate is divinely delicious, mouthwateringly smooth and unfortunately full of fat.

But reducing the fat content of the confection makes it harder and less likely to melt in your mouth.

That’s why scientists are investigating additives that could reinstate chocolate’s delightful properties in these lower-fat treats.

Now, researchers report in ACS’ Journal of Agricultural and Food Chemistry an analysis that sheds light on how adding limonene could improve lower-fat versions’ texture and ability to melt.

Flavor and sweetness make strong contributions to the pleasant experience of eating chocolate, but so do look and feel.

Reducing the fat in chocolate, however, often ruins its texture and viscosity.

Previous research has shown that adding limonene – a compound found in lemons and oranges – results in a smoother, softer chocolate that melts more easily than typical reduced-fat chocolates.

Annelien Rigolle and colleagues at KU Leuven in Belgium sought to investigate exactly how limonene impacts chocolate production.

They focused on one part of this process: the crystallization of one of its main ingredients, cocoa butter, which undergoes several important transformations at different times and temperatures.

The researchers examined crystallization at 63 °F and 68 °F using differential scanning calorimetry and X-ray diffraction to examine cocoa butter profiles when limonene was added.

Surprisingly, they found that adding the compound accelerated cocoa butter crystallization at 63 °F, but inhibited cocoa butter crystallization at 68 °F.

Varied concentrations of limonene also affected the crystallization steps of the cocoa butter differently, so they could ultimately affect the texture of chocolate.

The study suggests that carefully choosing the amount of limonene and the temperature at which chocolate is processed could lead to a smoother, more luxurious reduced-fat chocolate.
