Food Chemistry By Owen R. Fennema
Food Chemistry (third edition) is edited by Owen R. Fennema (University of Wisconsin-Madison, Madison, Wisconsin) and published by Marcel Dekker, Inc. in 1996. For many years, an acute need has existed for a food chemistry textbook that is suitable for food science students with backgrounds in organic chemistry and biochemistry. This book is designed primarily to fill the aforementioned […]
Testing for Cations By Sodium Hydroxide & Ammonia Precipitates [Infographic]
Sodium Hydroxide (NaOH) solution or aqueous Ammonia solution can be added to the solutions containing metal ions in order to discern their identity. The colour precipitate from by the reaction can be used to determine the metal identity. In some cases, the precipitate dissolves in excess NaOH and Ammonia. In the following Test for Cations […]

Metal Ion Flame Test Colours [Infographic]
A flame test is an analytical procedure used by chemists to detect the presence of particular metal ions, based on the colour of the flame produce. When heated, the electrons in the metal ion gain energy and can jump into higher levels. Because this is energetically unstable, the electrons tend to fall back down to […]

Colours of Transition Metal Ions in Aqueous Solution [Infographic]
Transition Metals form coloured compounds and complexes. These colours can be vary depending on the charge on metal ion, and the number and type of groups of atoms (called ligands) attached to the metal ion. In aqueous solutions, the ions form colours with complexes. Electrons are arranged around the nucleus of the metal atom in orbitals, […]
Food Chemistry By H.D. Belitz, W. Grosch and P. Schieberle
Food Chemistry (4th revised and extended edition) is written by Professor Dr. Hans-Dieter Belitz, Professor em. Dr. Werner Grosch and Professor Dr. Peter Schieberle and published by Springer in 2009. The very rapid development of food chemistry and technology over the last two decades, which is due to a remarkable increase in the analytical and manufacturing possibilities, makes the complete lack […]
