BACKGROUND:
Bee pollen has been regarded as a complete nutrition supplement for human diet, but the nutrient absorption and biological activities may be restricted by the complex pollen wall. The aim of this study was to explore the effects of ultrasonic and ball-milling treatment on nutritional components release and antioxidant activities in vitro and in vivo of rose (Rosa rugosa) bee pollen.
RESULTS:
After wall-breaking treatments, the bee pollen walls were broken in varying degrees, nutrients were released and in vitro and in vivo antioxidant activities of bee pollen were improved. The scavenging activities of DPPH and ABTS radicals as well as ORAC were improved. In aging mice, wall-breaking treatments led to better organ recovery, superoxide dismutase (SOD) and catalase (CAT) activities enhancements and malondialdehyde (MDA) reduction. In addition, eight compounds of rose bee pollen ethanol extract including Isorhamnetin 3-O-diglucoside and N', N″, N‴-Dicaffeoyl p-coumaroyl spermidine were identified by UPLC-ESI-QTOF-MS/MS assay.
CONCLUSION:
This study showed that the ultrasonic treatment had greater wall-disruption effects of bee pollen on nutrients release and antioxidant activities promotion. In conclusion, rose bee pollen under wall-breaking treatments may have potential application value as ingredient in functional food processing.
