Article Abstract
A method is described for the determination of ethoxyquin (1,2-dihydro-6-ethoxy-2,2,4-trimethylquinoline) in paprika and chili powder. Ethoxyquin is extracted from the spice with hexane and partitioned into 0.3N HCl. After adjusting the solution to pH 13-14, ethoxyquin is extracted into hexane, and the hexane layer is evaporated to dryness. An acetonitrile solution of the residue is then analyzed by reverse phase high pressure liquid chromatography with detection at 254 nm. The mobile phase is water-acetonitrile with ammonium acetate buffer. Recoveries from samples fortified at 50, 100, and 200 ppm averaged 92% with a coefficient of variation of 2.3%. The method was applied to a number of commercial samples of paprika and chili powder. Ethoxyquin was found in paprika samples at levels up to 63 ppm and in chili powder samples at levels up to 20 ppm.

Background: The 11+Myco MS-PREP® Immunoaffinity Column (IAC) contains a gel suspension of monoclonal antibodies specific to the toxins of interest. Following sample extraction, the IAC is used for cleanup and concentration of mycotoxins prior to analysis by Liquid Chromatography with Tandem Mass Spectrometry (LC-MS/MS).
Objective: This study evaluated the IAC with LC-MS/MS method for Performance Tested Methods SM certification for simultaneous determination and confirmation of Aflatoxins B1, B2, G1, G2, and M1; Deoxynivalenol, Fumonisins B1, B2, and B3; Ochratoxin A; T-2; HT-2; and Zearalenone from corn, wheat, cereal-based baby food (with and without dairy ingredients), paprika, chili powder and animal feed.

Cadmium (Cd) is a toxic heavy metal widely distributed in foodstuffs. In Mexico, few studies have evaluated Cd content in foods. This study aimed to determine Cd concentrations in foodstuffs that are highly consumed and bought in Mexico City to identify foods exceeding the Maximum Level (ML) and to assess the health risks of theoretical Cd intake from a diet following the Mexican Dietary Guidelines.

Background: The rising prevalence of colorectal cancer (CRC) may be attributed to various nutritional and behavioural factors, making both factors as important topics for discussion to the layman and the oncology community.
Objective: To explore additional dietary risk factors, other than those already known, according to the Ayurvedic perspective in CRC patients.
Methods: Detail dietary data was collected from 420 patients of CRC and 116 healthy volunteers registered at our institute with the help of a food frequency questionnaire.

Biochar-based fertilizers show promise in enhancing nutrient utilization and soil health, but their slow-release performance remains a challenge. Herein, hydrogel membranes incorporating iron oxide nanoparticles within a polyvinyl alcohol and starch matrix (Fe/PVA/ST) were synthesized. These membranes were utilized to coat compound fertilizer particles, with biochar powder applied to the outer layer to form what is known as Fe/PVA/ST-BSRFs.
