Effects of superheated steam treatment on the inactivation of microbial counts, enzyme activity and the inhibition of lipid oxidation of rape bee pollen
The effect of superheated steam (SHS) treatment on the quality characteristics of rape bee pollen were studied, and the efficiency of inactivation and inhibition of lipid oxidation were analyzed to investigate the differences between SHS and cobalt-60 isotope (<sup>60</sup>Co) radiation treatment. The number of total plate count (TPC) and mold colonies (MC) remained within the limits of the standards after SHS treatment at 140 ℃ for 2 min. Neither TPC nor MC were detected after <sup>60</sup>Co irradiation. Peroxidase (POD) and polyphenol oxidase (PPO) activities significantly decreased with increasing temperature and duration of SHS, while <sup>60</sup>Co radiation completely inactivated PPO. Compared to <sup>60</sup>Co radiation, SHS treatment inhibited the deterioration of rape bee pollen by avoiding hydroperoxide production and lipid oxidation due to lack of oxygen. These results suggested SHS under 140 ℃ for 2 min was the most suitable to inactivate the microorganisms and enzymes in rape bee pollen with minimal lipid oxidation.
