Resumo(s)
After its collection the bee pollen can present moisture contents that can range
from 18% to 25%. Thus, it is necessary to reduce the moisture content in order to maintain
bee pollen overall nutritional quality and microbiological safety. Moreover, several
studies have recently highlighted the beneficial biological properties of bee pollen, which
may also be influenced by the preservation techniques applied to reduce the moisture
content. Therefore, the main objective of this work is to provide an insight regarding the
potential influence of preservation techniques on the nutritional value, microbiological
quality, and antioxidant properties of bee pollen. The bee pollen, presented an initial
moisture content of 13.8%, which was subsequently reduced to 9.6%, 9.8%, 10.1%, and
5.8% by oven-drying at 35ºC, 40ºC, and 45ºC, and freeze-drying, respectively. The
nutritional value, microbiological quality, and antioxidant properties of the preserved bee
pollen were assessed throughout time during a period of 6 months. In general, the
different treatments showed no significant immediate impact on the nutritional value and
microbiological loads of bee pollen, but some changes were observed on the antioxidant
properties. Also, changes were observed after one month of storage, mostly in total viable
counts and lactic acid bacteria.
