蜂蜜濃度如何測(cè)定

|OK蜜蜂網(wǎng)
    購買蜂蜜的時(shí)候,能看到蜂蜜的包裝上有蜂蜜濃度的標(biāo)識(shí)。蜂蜜的濃度到底是如何測(cè)試出來的?蜂蜜濃度為生命會(huì)有高有低呢?  衡量蜂蜜的濃度一般用波美計(jì)進(jìn)行測(cè)定,也可用比重法進(jìn)行計(jì)算或以糖量儀測(cè)定其糖分含量,從而測(cè)得含水量的高低和濃度高低(詳見表1)                          蜂蜜濃度的高低,決定于釀造時(shí)間的長短。時(shí)間越長水分越少,濃度越高,反之亦然。因此取蜜間隔時(shí)間越長,濃度越高而水分含量越低,取蜜間隔時(shí)間越短,產(chǎn)量雖高,但濃度低,含水量高,易發(fā)酵變質(zhì)。                                  表1  蜂蜜含水量與波美度、比重、含糖量對(duì)照表
