Quality and Regulatory Compliance of Commercial Blossom and Pine Honeydew Honeys in the Turkish Retail Market
This study evaluated the quality and regulatory compliance of 22 commercial blossom and pine honeydew honeys in Türkiye, finding that while most samples met established standards, two blossom honey samples were non-compliant due to excessive hydroxymethylfurfural (HMF) levels and insufficient proline content.

Honey is more than just a sweet spread on toast; it is a complex natural product whose quality depends on where the bees foraged and how the honey was handled after collection. Bees make two main kinds of honey: blossom honey, which comes from the nectar of flowers, and honeydew honey, which is made from the sugary secretions of insects living on trees, particularly pine trees. Because honey is valuable, it is sometimes mixed with cheaper syrups or heated too much during processing, which can ruin its natural properties. To ensure that the jar on the shelf is genuine and safe to eat, scientists rely on a set of rules that measure things like how much water is in the honey, how acidic it is, and what specific sugars it contains. These measurements act as a fingerprint, telling experts if the honey is fresh, if it has been heated, and whether it truly comes from the type of flower or tree it claims to.
In Turkey, a country that produces a vast amount of the world's honey and is the top producer of pine honey, researchers recently set out to check the quality of honey sold in major supermarkets. They bought twenty-two different jars, fourteen labeled as blossom honey and eight as pine honeydew honey, from five large retail chains. The goal was to see if these commercial products met the strict national standards for purity and freshness. The team did not just look at the labels; they took the honey into a laboratory to measure its physical and chemical makeup. They checked how much water was present, measured the acidity, and counted the activity of natural enzymes that indicate freshness. They also looked for a specific compound called hydroxymethylfurfural, which forms when honey is overheated or stored for too long, and they used advanced machines to map out the exact types and amounts of sugars inside each sample.
The results showed that the vast majority of the honey sold in these Turkish stores is of high quality and follows the rules. Almost every sample had the right amount of water and natural enzymes, and the sugar profiles matched what is expected for genuine honey. However, the study did find a few exceptions. Two samples of blossom honey failed to meet the standards. Both of these jars contained too much of the heat-damage compound, and one of them also lacked enough of a specific amino acid called proline, which is a sign of honey maturity. In contrast, all eight samples of pine honeydew honey passed every test without issue. This suggests that while the market is generally reliable, there are still occasional lapses in quality control for certain types of blossom honey.
The researchers also discovered clear differences between the two types of honey that go beyond just taste. The pine honeydew samples were consistently more acidic and conducted electricity much better than the blossom honeys, a difference so distinct that it can be used to tell the two types apart with certainty. On the other hand, the blossom honeys contained higher levels of fructose and glucose, the primary sugars that give honey its sweetness. While the pine honey was darker and richer in minerals, the blossom honey was sweeter in terms of its sugar composition. The study also looked at minor, less common sugars that appear in tiny amounts. These minor sugars varied widely from jar to jar, showing that even within the same type of honey, nature produces a unique mix every time.
Ultimately, the study confirms that the honey available in Turkish supermarkets is largely trustworthy, with only a small number of products falling short of the required standards. The few failures found were specific to blossom honey and were linked to issues with heat damage or maturity, rather than a widespread problem with the entire industry. By combining traditional tests with a detailed look at the sugar makeup, the researchers provided a clear picture of what is actually in the jars consumers buy. The work highlights that checking multiple signs of quality together gives a much better answer than relying on a single test, ensuring that the honey on the shelf remains a pure and natural product.
