“…The chemical composition of bee pollen varies according to the plant origin, geographical location, and environmental conditions (Komosinska-Vassev et al, 2015;Nogueira et al, 2012). Despite the variations, bee pollen is normally acidic, with a pH between 3.4 and 5.1, and composed of 20% proteins (including essential amino acids), 55% total carbohydrates with 25% reducing sugars (primarily fructose and glucose), 5% lipids, 1.6% phenolic compounds, 0.7% vitamins, and 1.6% bioelements (macro and micronutrients) (Campos et al, 2008;Komosinska-Vassev et al, 2015;Nogueira et al, 2012).…”

Agr. 45(1): 51-63. Bee pollen is a conglomerate of plant pollens, and its nutritional contents include bioactive compounds with antioxidant/antiradical potentials. These potentials are conditioned by botanical origin. In Chile, the native flora is diverse and promising in terms of bioactive compounds, but many plants grow in metal-polluted areas. The associated bioaccumulation could negatively affect the antioxidant/antiradical abilities of bee pollen. To assess the relationship between the bioaccumulation of metals and the antioxidant activity of pollen, complete bee pollen was collected near and far from the Llaima Volcano, albeit in ranges that ensured the same botanical origins. Mellisopalynological analysis determined Escallonia rubra pollen was the most abundant native flora in complete bee pollen. Therefore, E. rubra pollen collected near and far from the Llaima Volcano was evaluated for the following: phenolic compounds via colorimetric assays; antioxidant activity via ferric reducing/antioxidant power assays; antiradical activity via 1,1-diphenyl-2-picrylhydrazyl radical assays; and metal contents via inductively coupled plasma optical emission spectrometry. Llaima samples had higher Cu and Fe but lower Mn contents and lower antioxidant and antiradical capacities than did the control samples. These results were supported by subsequent fortification assays in Llaima E. rubra samples. In fortified samples with significantly higher metal contents, antiradical and antioxidant abilities decreased. Moreover, shifts in migration times were found for naringenin, rutine, and caffeic acid after capillary electrophoresis (CE) analysis in fortified samples. In conclusion, the results indicated an inverse correlation between metal contents and antioxidant/ antiradical potentials in bee pollen.

Bee pollen in allergy and immunology. Short review

S u m m a r yBee pollen is a natural resource -pollen collected by bees and stored in the beehive with various bee enzymes added as it is a mixture of plants pollen and bee saliva. It is rich source of various nutrients, among them exogenous amino acids. Therefore, it can be a good and natural dietary supplement. New possibilities for bee pollen usage arise every day, yet it can also be a threat. Although bee pollen can act as an immunostimulant and anti-allergic agent, it is also and maybe even primarily allergic or cross-reactive with many allergens. A number of bee pollen allergy cases was described worldwide. A caution is therefore needed before ingestion or any other form of administration, especially in case of children or individuals with atopic predispositions. Anti-allergic attributes and immunostimmulation ability still need further research. key words: bee pollen, bee pollen allergy, bee pollen immunology Bee pollen -what is it exactly?Bee pollen is a natural resource -a pollen collected by bees and stored in the beehive with various bee enzymes added as it is a mixture of plants pollen and bee saliva.

Playing an instrumental role in the life of plants, pollen microparticles are one of the most fascinating biological materials in existence, with abundant and renewable supply, ultrahigh durability, and unique, species-specific architectural features. Aside from their biological role, pollen microparticles also demonstrate broad utility as functional materials for drug delivery and microencapsulation, and increasingly for emulsion-type applications. As natural pollen microparticles are predominantly hydrophobic, developing robust surface functionalization strategies to increase surface hydrophilicity would increase the range of colloidal science applications, including opening the door to interfacing microparticles with biological cells. This research investigates the extraction and light-induced surface modification of discrete pollen microparticles from bee-collected pollen granules toward achieving functional control over the responses elicited from discrete particles in colloidal science and cellular applications. Ultravioletozone treatment is shown to increase the proportion of surface elemental oxygen and ketones, leading to increased surface hydrophilicity, enhanced particle dispersibility, tunable control over Pickering emulsion characteristics, and enhanced cellular adhesion. In summary, the findings demonstrate that light-induced surface modification improves the functional properties of pollen microparticles, and such insights also have broad implications across materials science and environmental science applications.
