      Beer is a complex alcoholic beverage made from barley (malt), hops, water and yeast. Chemically, beer can be considered as a water-ethanol solution with an acid pH (pH around 4.2) which contains hundreds of dissolvedmolecules. Thermodynamically, a bottle of beer is a closed system and will thus strive to reach a status of minimal energy and maximal entropy. Consequently, molecules can undergo different reactions and change their chemical composition during storage. Moreover degradation of molecules to concentrations below the flavour threshold may cause loss of initial fresh beer flavours. In this article, we discussed the fundamental reactionsin beer and their mechanisms from brewing to storage.

      Organic colorants are an important type of compounds mainly characterized by the presence of conjugated moieties and color-generating functions (chromophores), such as carbonyl, azo or nitroso functions. They find various applications in coloring all kinds of substances – from plastics to clothes – but are unfortunately often synthesized by toxic and environmentally harmful routes. This review first explains the physicochemical basis of colorants, then gives an introduction to their classifications and general syntheses and ends with a highlight of recent advances in the environmentally friendly hydrothermal synthesis of colorants.

      Enseñanza de la Química Sostenible en las carreras de ingeniería
      (Pontificia Universidad Católica del Perú, 2018-07-23) Soledad Rodríguez, Beatriz Elena
      Green Chemistry was born in 1990 in order to prevent environmental pollution, improve the environment and quality of life. It seeks to create awareness in both the scientific and industrial communities, the importance of providing goods and services that are in line with population growth, in a way that does not contaminate or diminish social welfare. Sustainable engineering has developed as an extension to sustainable chemistry,with the aim of designing products and processes that minimize pollution and companies that want to be recognized as leaders in a more global and competitive market must seek to bring value to their investments and the socio-economic environment in which they operate, with a high level of environmental protection.
