A recent study by the Kwame Nkrumah University of Science and Technology (KNUST) has raised alarm over the safety of tomato paste products sold in Ghana. The research discovered traces of erythrosine, also known as Red Dye No. 3, and starch in some tomato paste samples, both of which are banned by the Ghana Food and Drugs Authority (FDA) for use in such products.
Erythrosine is a synthetic dye often used in candies, toffees, and beverages, where it is sometimes labeled simply as “Number 3.” Despite its widespread use in other products, the FDA prohibits its inclusion in tomato paste due to its associated health risks.
Starch is also disallowed in tomato paste formulations for similar safety reasons. The study was led by Dr. Abena Boakye from the Department of Food Science and Technology at KNUST, who called for stricter regulatory enforcement.
“The presence of these substances in tomato paste is worrying. The FDA should extend its oversight beyond tomato products to include confectioneries, drinks, and other items containing erythrosine,” she stated.
Dr. Boakye’s recommendations align with global health trends. In January, the U.S. Food and Drug Administration (USFDA) completely banned erythrosine from all food products, giving manufacturers a two-year timeline to phase it out due to its potential health hazards.
With tomato concentrate being a staple in many Ghanaian households and restaurants, the study’s findings emphasize the urgent need for enhanced food safety measures. Researchers urge policymakers to take swift action in ensuring that only safe and compliant food products reach consumers, protecting public health from harmful additives.
