Chemical Composition and Bioactivity of Laboratory-Fermented Bee Pollen in Comparison with Natural Bee Bread

نویسندگان

چکیده

Bee bread is a valuable product obtained from the hive on relatively small scale, while bee pollen more easily available. Therefore, an effective laboratory method of converting into substitute desired. The aim research was to verify influence selected factors (temperature, ultrasound) quality using Lactobacillus rhamnosus inoculum. composition fermented analyzed Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), Raman spectroscopy, and SDS-PAGE compared natural original pollen. In vitro biological activity assessed as antioxidant yeast model (BY4741 sod1∆ strains). Fermentation occurred spontaneously after inoculation, demonstrated by lower pH higher lactic acid content. spectroscopy ICP-OES confirmed changes in initial Compared bread, showed content polyphenols comparable activity; moreover, it accelerated growth rate. addition, protective effect observed for Cu/Zn-superoxide dismutase 1 (sod1∆ mutant exposed hydrogen peroxide-induced oxidative stress). fermentation temperature (25 °C) produces bee-bread-like product, use ultrasound starter culture seems have no positive effect.

Fatty Acid and Proximate Composition of Bee Bread.

Palynological spectrum, proximate and fatty acid (FA) composition of eight bee bread samples of different botanical origins were examined and significant variations were observed. The samples were all identified as monofloral, namely Castanea sativa (94.4%), Trifolium spp. (85.6%), Gossypium hirsutum (66.2%), Citrus spp. (61.4%) and Helianthus annuus (45.4%). Each had moisture content between 1...

Chemical Composition and Biological Activities of Mono- and Heterofloral Bee Pollen of Different Geographical Origins

Recent research shows variations in pollen chemical constituents and, consequently, in their therapeutic properties. Mono and multifloral bee pollen extracts were investigated for antioxidant and enzyme inhibitory activity properties, phenolic compounds and fatty acid composition. Generally, Eucalyptus spp. and multifloral extracts exhibited potent inhibitory activity against α-amylase, acetylc...
