HP\u2019S are very stable compounds at ambient conditions and are harmful to human health. Therefore, the evaluation of the degree of oil oxidation is an excellent tool for ensuring food safety. The peroxide value (PV) is the main parameter used for quality control in oils. Herein, we propose an alternative electrochemical method to the classical iodometric titration method most widely used for determining the PV. Our approach is based on the electrochemical quantification of hydroperoxides\/peroxides in an organic solvent medium (acetonitrile and organic ammonium salt) using a composite electrocatalyst\u2013glassy carbon electrode modified with 2D-nanomaterial graphitic carbon nitride doped with Co3O4. Calibration was made by the method of standard addition using benzoyl peroxide (BPO) as a model peroxide compound, dissolved in chloroform and added to fresh Rivana-branded anti-cellulite oil, used as a model oil sample. Calibration plots showed a linear response and the very good reproducibility of the analytical result (R2 \u02c3 0.99). Further, in terms of accuracy, the method showed good results, since the BPO quantitative analysis was close to the theoretical response. In addition, the accuracy of the electrochemical method was compared with that of the standard iodometric titration method for determining the PV of vegetable fats (according to a standard method). Finally, using the electrochemical method, the concentration of peroxides was determined in a real sample\u2014an anti-cellulite oil of the trademark Rivana with an expired shelf life.<\/jats:p>","DOI":"10.3390\/molecules30020374","type":"journal-article","created":{"date-parts":[[2025,1,17]],"date-time":"2025-01-17T11:24:56Z","timestamp":1737113096000},"page":"374","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Electrochemical Method for the Assay of Organic Peroxides Directly in Acetonitrile"],"prefix":"10.3390","volume":"30","author":[{"given":"Vanina","family":"Ivanova","sequence":"first","affiliation":[{"name":"Department of Physical Chemistry, Plovdiv University \u201cPaisii Hilendarski\u201d, 24, Tzar Assen Str., 4000 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6105-2715","authenticated-orcid":false,"given":"Mariya","family":"Pimpilova","sequence":"additional","affiliation":[{"name":"Laboratory of Biologically Active Substances, Institute of Organic Chemistry with Centre of Phytochemistry, Bulgarian Academy of Sciences, 139 Ruski Blvd., 4000 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1687-0823","authenticated-orcid":false,"given":"Maria","family":"Stoyanova","sequence":"additional","affiliation":[{"name":"Department of Physical Chemistry, Plovdiv University \u201cPaisii Hilendarski\u201d, 24, Tzar Assen Str., 4000 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7082-8266","authenticated-orcid":false,"given":"Nina","family":"Dimcheva","sequence":"additional","affiliation":[{"name":"Department of Physical Chemistry, Plovdiv University \u201cPaisii Hilendarski\u201d, 24, Tzar Assen Str., 4000 Plovdiv, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118345","DOI":"10.1016\/j.indcrop.2024.118345","article-title":"Whey protein isolate-stabilized gardenia fruit oil nanoemulsions: Ultrasonic preparation, characterization and applications in nutraceuticals delivery","volume":"212","author":"Wang","year":"2024","journal-title":"Ind.
