AI Article Synopsis
- Bee pollen is a popular food supplement known for its bioactive substances and energy-boosting properties, containing proteins, amino acids, lipids, and glucosinolates.
- A study analyzed 72 bee pollen samples and 11 commercial samples from different Spanish regions using advanced liquid chromatography to determine their glucosinolate content.
- The results showed that glucosinolate levels could successfully identify the geographical origin and harvesting periods of the bee pollen samples.
Article Abstract
Bee pollen is currently one of the most commonly consumed food supplements, as it is considered to be a good source of bioactive substances and energy. It contains various health-promoting compounds, such as proteins, amino acids, lipids, as well as glucosinolates. In the present study, the glucosinolate content was determined, by means of ultra-performance liquid chromatography coupled to a quadrupole time-of-flight mass detector, in 72 bee pollen samples from four different apiaries in Guadalajara (Spain), harvested in three different periods. In addition, 11 commercial multifloral samples from different Spanish regions were also analyzed. The aim was to verify the suitability of these compounds as biomarkers of their geographical origin, and to test their potential for distinguishing the harvesting period. By means of a canonical discriminant analysis, it was possible to differentiate the apiary of origin of most of the samples, and these could also be clearly differentiated from the commercial ones, simply as a result of the glucosinolate content. In addition, it was also demonstrated for the first time that bee pollen samples were capable of being differentiated according to the time of harvesting and their glucosinolate content.

The volatile profile of bee pollen samples from Central and Eastern Europe was investigated by headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry-olfactometry (GC-MS-O). Sampling conditions were optimized for the extraction of volatiles. Pollen odorants were extracted with six different fiber coatings, five various extraction times, three diverse extraction temperatures and three differing desorption times.

Honey is a natural product gathered by honeybees from the pollen and nectar of various plants and flowers. The homeland of the Caucasian honey bee, which draws attention with its honey production and is one of the most productive bee races known in the world, is Northeastern Anatolia in Türkiye. This study aims to determine and correlate the phenolic content and antioxidant activity of 54 honey samples obtained from the most important gene centers of the Caucasian bee in Türkiye.

Recently, it has been shown that sugar‑conditioned honey bees can be biased towards a nectarless dioecious crop as kiwifruit. The challenges for an efficient pollination service in this crop species are its nectarless flowers and its short blooming period. It is known that combined non-sugar compounds (NSCs) present in the floral products of different plants, such as caffeine and arginine, enhance olfactory memory retention in honey bees.

The honey bee () is the most widely managed pollinator and is vital for crop fertilization. Recently, bee colonies have been suffering high mortality rates, exacerbated by factors such as land-use changes and the use of pesticides. Our work aimed to explore the residues of pesticides in honey-bee-collected pollen and how this contamination was affected by seasonality and the landscape composition.
