Chemical and bioactive characterization of pot-pollen produced by Melipona and Scaptotrigona stingless bees from Paria Grande, Amazonas State, Venezuela

In vitro and In vivo digestion comparison of bee pollen with or without wall‐disruption

“…Nevertheless, some studies have claimed that bee pollen does not need wall‐disruption. Two reasons were proposed: first, humans and animals can digest and absorb the nutrients through the pollen germination 10 ; second, the gastrointestinal tract of humans and animals can break the bee pollen wall 18,19 . Consequently, it remains controversial as to whether bee pollen should be wall‐disrupted or not.…”

“…The protein contents of pollen samples were determined following the Kjeldahl method with slight modification 18 . The bee pollen samples before and after the wall‐disruption were weighed and dissolved into a bee pollen solution (12.5 mg mL –1 ).…”

Physicochemical characterization, antioxidant and antifungal activity of three stingless bee pollen aggregate (Apidae: Meliponini) from Soconusco, Chiapas

“…Por otra parte, estudios recientes con productos de abejas sin aguijón, han demostrado que estos promueven mayor tasa de epitelización en heridas y efecto antiinflamatorio y antimicrobiano que la abeja europea o melífera (Rao et al, 2016). La actividad antimicrobiana se ha evaluado in vitro contra distintas bacterias de importancia médica: Listeria monocytogenes, Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa, Streptococcus pyogenes, Proteus mirabilis, Staphylococcus aureus y diferentes especies fungosas del género Candida (Cabrera y Montenegro 2013;Zainol et al, 2013;Vit et al, 2016). Extractos metanólicos y etanólicos de polen, así como mieles de A. mellifera y de diversas especies de abejas sin aguijón han tenido efectiva actividad antimicrobiana contra hongos de interés médico y agrícola: Alternaria alternata, Botrytis cinerea, Fusarium oxysporum y C. gloeosporioides (Cabrera y Montenegro 2013;Albores-Flores et al, 2018).…”

“…De los productos de colmena, el polen está compuesto por subproductos del gametangio masculino floral que colectan las abejas y cuenta con un alto contenido nutrimental, constituido por carbohidratos (13 y 55%), proteínas (10 y 40%), lípidos (1-10%) y fibra cruda (0.3 y 20%), además de minerales, oligoelementos, vitaminas, hand, recent studies with stingless bee products have shown a higher rate of epithelialization in wounds and greater anti-inflammatory and antimicrobial effects than those of European or honeybees (Rao et al, 2016). The antimicrobial activity has been evaluated in vitro against different medically important bacteria: Listeria monocytogenes, Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa, Streptococcus pyogenes, Proteus mirabilis, Staphylococcus aureus, and different fungal species of the Candida genus (Cabrera and Montenegro 2013;Zainol et al, 2013;Vit et al, 2016). Methanolic and ethanolic extracts of pollen, as well as honey of A. mellifera and different stingless bee species, have shown an effective antimicrobial activity against fungi of medical and agricultural interest: Alternaria alternata, Botrytis cinerea, Fusarium oxysporum and C. gloeosporioides (Cabrera and Montenegro 2013;Albores-Flores et al, 2018).…”

Pot-pollen supplementation reduces fasting glucose and modulates the gut microbiota in high-fat/high-sucrose fed C57BL/6 mice

“…Apart from macronutrients and fiber, this product, also known as samora, sabura, or sambura in Brazil and zamorra in Argentina, contains a variety of polyphenols with known antioxidant activity. [14][15][16] Also, several of these compounds are known modulators of the gut microbiota. 17 Despite its content of bioactive compounds, the effect of potpollen ingestion on glucose metabolism and the gut microbiota has not yet been investigated.…”
