Ultrasound-Assisted Extraction of Inorganic Elements and Antioxidants from Gingerbread Cookies Using Natural Deep Eutectic Solvents

In the present study, ultrasound-assisted extraction using deep eutectic solvents was pro- posed for the preparation of uniced and iced gingerbread cookies prior to the determination of four macronutrients (potassium, sodium, magnesium, calcium), four micronutrients (manganese, zinc, iron, copper), the presence of toxic metal (cadmium), and antioxidant capacity. With the addition of 30% water in each green solvent, three acidic deep eutectic solvents, comprising xylitol with malic acid,...
