Preservatives and preservation techniques give us access to the rich flavors of fresh food we all love while being away from the fields. Preservation techniques have been known since antiquity but they became more sophisticated after the Industrial Revolution as cities became more populous. Nowadays, preservatives are part of our daily life. They have become even more important as our society reaches for sustainability and food waste reduction. But the reader probably has a burning question: are they safe? The short answer is yes, they are safe. Let’s take a look at the history and chemistry of some of the most common chemicals used in food preservation techniques. With this information, the readers can decide on their own.

The determination of isotope effects is an important tool in the study of chemical transformations. Very common in the liter­ature is the use of deuterium isotope effects, which is typically covered in many textbooks. Unfortunately, heavy atom isotope effects have not received the same attention despite its great rel­evance. This article will serve as an introduction to this very important topic.

The global consumption of coffee has experienced a notable increase in the last decade. The high global consumption of coffee is mainly attributed to its psycho-stimulant effects, influenced by genetic factors, and the perceived health benefits, although adverse effects are also recognized in some individuals. The complex chemistry of coffee, influenced by the bean, roasting, and preparation, impacts its flavor and properties. This article explores the chemistry of coffee, from the Arabica and Robusta species and their origin, to the processing methods (wet/dry) that modify the green bean. Transformations during roasting (Maillard reaction) are analyzed, as well as how roasting and extraction affect compounds like diterpenes and caffeine, and the sensory characteristics of coffee. Finally, the use of chemical techniques to determine the origin and purity of coffee is highlighted, undersc...
