The present review focuses on electrochemical methods for ascorbic acid assessment. The
occurence, role, biological importance of vitamin C, as well as the non-electrochemical …

A sensitive and selective electrochemical sensor, based on reduced graphene oxide and
gold nanoparticles obtained by simple co-electrodeposition, was developed for the detection …

Abstract High Pressure Processing (HPP) is a well‐established nonthermal technology for
ensuring microbial safety and nutritional quality of foods. Ascorbic acid (AA) is highly labile …

Okra is consumed as a vegetable by populations in Africa and Asia and particularly in Egypt.
In this study, we investigated some nutritional components of okra grown in four different …

A method was developed for assessing ascorbic acid concentration in fruit juices and wine
by differential pulse voltammetry. The oxidation peak for ascorbic acid occurs at about 530 …

Vitamin C contents measured as ascorbic acid, in thirty-eight samples of tropical leafy
vegetables and foods were determined by two methods. One was by cyclic voltammetry …

Fabrication of electrodes based on a metal-free catalyst with desirable sensitivity, selectivity,
and stability has been given considerable interest. Microporous sulfur-doped carbon …

In this work, the near-neutral photo-Fenton process, as a means of wastewater disinfection,
was enhanced by the addition of Organic Acids (OAs), namely citric, ascorbic, tartaric and …

Methods that can directly and sensitively quantify a set of correlative substances lack of
chromophores in pharmaceuticals are persistently desired. Here, by facile preparation of Pt …

Purpose The importance of studying polyphenolic compounds as natural antioxidants has
encouraged the search for new methods of analysis that are quick and simple. The synthesis …
