蜂粮酿制过程中花粉粒活力和水活度的测定

Determination of water activity and pollen particles activity during the process from corbicular pollen to bee bread

测定手采花粉、新鲜蜂花粉、1日蜂粮、2日蜂粮、3日蜂粮、4日蜂粮、5日蜂粮样品中花粉粒活力分别为 3 1 4%、3 5 6%、1 8 1 %、1 6 4%、7 8%、1 3 %、0 ,5日以后花粉粒丧失活力。测定新鲜蜂花粉、晒干花粉、1日、5日、1 0日、1 5日、2 1日、60日蜂粮的水活度分别是 0 65 1、0 2 0 8、0 80 9、0 60 5、0 60 2、0 5 98、0 60 7、0 60 0。

Percent of pollen particles activity in floral pollen, corbicular pollen, 1\|,2\|,3\|,4\|,5\|day bee bread were 31 4%、35 6%、18 1%、16 4%、7 8%、1 3%、0,respectively. The pollen particles lost activity after 5 days. The water activity of corbicular pollen, dried corbicular pollen and 1\|,5\|,10\|,15\|,21\|,60\|day bee bread were 0 651、0 208、0 809、0 605、0 602、0 598、0 607、0 600,respectively.
