It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect…

Rosa, Clarissa H.; Antelo, Francine; Rosa, Gilber R. – Journal of Food Science Education, 2018
A 4-week mini-project is proposed for an experimental Physical Chemistry course applied in Food Science training. Activities include preparation of beet extract for the extraction of betanins and analysis of the kinetics of betanins in thermal degradation at three temperatures (60, 70, and 80 ºC). In addition to developing common laboratory…
