Sodium hydroxide (NaOH), sulfuric acid (H₂SO₄), dichloromethane (CH₂Cl₂), sodium sulfate (Na₂SO₄), and methanol (MeOH) (High Performance Liquid Chromatography grade) were purchased from Vetec® (Brazil). For the parasitological tests, thiabendazole, tween® 80, levamisole, sodium hypoclorite (NaOCl) and sodium chloride (NaCl) were purchased from Sigma-Aldrich (USA). Rezasurin used in cytotoxicity evaluation was also purchased from Sigma-Aldrich (USA).

Chocolate Samples Fatty Acid Analysis

Thirty-two chocolate samples (white, dark, and milk chocolates) from different national and multinational brands produced in Brazil were used to carry out this research. Samples were purchased in local markets. The addition of PHVO is still acceptable in this country, and some products had high trans fats contents declared. All reagents used in the experiments were of analytical grade, and water used in aqueous solutions was purified by deionization (Milli-Q system; Millipore, Bedford, MA, USA). Methanol, potassium hydroxide (KOH) and sodium bisulfate (NaHSO4) were purchased from Panreac Química S.A. (Madrid, Spain). Hexane, isopropanol, and sodium sulfate (Na2SO4) were obtained from Vetec (Rio de Janeiro, RJ, Brazil). Analytical FAME standards (GLC-603, GLC-611, GLC-643, GLC-80, GLC-409) were acquired from Nu-Chek Prep Inc. (Elysian, MN, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
