Study: Microwaves and Ultrasound Boost CBD Extraction, Enhance Gluten-Free Hemp Cupcakes

Researchers from the University of Calabria used dynamic maceration supported by both microwave irradiation and ultrasonic waves to extract CBD oil from hemp inflorescences. They found that microwave treatment at 700 watts for 30 seconds produced 45.2 grams of extract, while 15 minutes of sonication yielded 53.2 grams. The analysis revealed that decarboxylated inflorescences—those exposed to heat to convert CBDA into CBD—produced the highest CBD concentrations. Microwave energy appeared especially effective in aiding cannabinoid extraction and enhancing decarboxylation, ultimately maximizing CBD content.

After extraction, the CBD-rich hemp oil was incorporated into gluten-free cupcakes, replacing butter, while hemp flour substituted for refined wheat flour. Rheological and textural tests showed that these modified cupcakes had properties comparable to conventional baked goods. The final product achieved a height of 4.1 cm and a measured hardness of 1.9 N, indicating a desirable texture and structure.

The findings support the use of advanced extraction techniques to improve the efficiency of CBD production and illustrate the potential of hemp-based ingredients for developing healthier, functional food products.

Researchers conclude by saying “In conclusion, our findings demonstrate that dynamic maceration assisted by ultrasound and microwave irradiation is an efficient method for extracting CBD-rich oil. Furthermore, hemp oil presents a viable alternative to traditional oils and fats for creating functional foods.”
