High ceramide content in fermented cocoa bean shells (Theobroma cacao L.)

Area of Science:

• Agricultural Chemistry
• Biochemistry
• Dermatology

Background:

• Cocoa beans are a significant agricultural product with various applications.
• Ceramides are vital lipids in human skin, playing a crucial role in barrier function.
• Understanding the biochemical composition of plant byproducts can reveal novel applications.

Purpose of the Study:

• To analyze the ceramide content in different parts of the cocoa plant.
• To identify specific types of ceramides present in fermented cocoa bean shells.
• To compare the ceramide profile of cocoa bean shells with other common plant materials.

Main Methods:

• Liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) was employed for analysis.
• Quantification of various ceramide species was performed.
• Comparative analysis with soybean, coffee bean, and peanut skins was conducted.

Main Results:

• Fermented cocoa bean shells exhibit a high concentration of ceramides.
• A specific hydroxy phytoceramide (t18:0-h24:0) was identified at 466.6 μg/g.
• The total ceramide content in cocoa bean shells surpasses that found in soybean, coffee bean, and peanut skins.

Conclusions:

• Fermented cocoa bean shells are a unique and abundant source of ceramides.
• The high ceramide content suggests potential applications in cosmetics and dermatology.
• Further research into the extraction and utilization of these ceramides is warranted.
