Citric Acid an overview ScienceDirect Topics

Kohtaro Kirimura, Isato Yoshioka, in Comprehensive Biotechnology (Third Edition), 2019. Abstract. Citric acid is one of the most widely used organic acids, and its annual worldwide output has reached 2.1 million ton in 2016. It is used as an acidulant and preservative in the food industries, and also used as a complexing agent and starting materials for functional compounds in the

Physicochemical and Additive Controls on the Multistep

2017-8-9  Mg reduces the precipitation rate of gypsum by more than half, most likely by blocking the attachment sites of the growth units, while citric acid only weakly hampers the growth of gypsum by lowering the effective supersaturation. In short, our results show that the nucleation mechanism is independent of the solution conditions and that Mg2
