Pesto: Testing the Italian classic

When it comes to Italian staple foods, pesto is one of the first that comes to mind. Unfortunately, recent tests of 20 pesto products sold by supermarkets have shown that foreign substances are common, with only two pesto products in this sample being marked as satisfactory.

More than half of the tested pesto products contained MOSH/MOAH, with some even containing very high levels.

MOSH/MOAH, also known as mineral oil hydrocarbons, are often inevitable in food. They are harmful when consumed in large amounts, with MOSH causing liver damage, and MOAH being carcinogenic. MOSH/MOAH can enter pesto during the packaging, production, and transport process. To avoid this, it is important to uphold quality standards at every stage of the production chain, from farm to fork.

Also, 15 of the 20 tested pesto products contained pesticide residue mixes. While all of the remaining pesto products contained pesticides, none of them exceeded the critical limits allowed by EU law.

Some products also contained plasticizers like diethylhexylphthalate (DEHP), which enter the food via canisters during the production and transportation process. The residues found, were however within the legal limits.


How can pesto manufacturers ensure a safe product?


Regular laboratory analyses contribute to offering your customers a product with long-term safety. If a product exceeds the legal allowance of harmful substances, it may be subject to product recalls. The Tentamus Group is your ideal partner in testing pesto for MOSH/MOAH and pesticides. We want to help you provide a product of high quality, which keeps harmful substances within the legal boundaries. We offer accurate results for pesticide analyses within 24 hours of receiving the sample, and also quantify all harmful substances the product may contain. This guarantees a marketable product.

Furthermore, we perform sensory analyses on foods to ensure the product is as desirable as it can be for the consumer. This includes testing for taste, texture, smell, and appearance.
