黄瓜清香味甜是人们喜食的蔬菜之一。但我们有时也会吃到带有苦味的黄瓜,是什么东西使黄瓜产生苦味呢?经农业科学家分析,有一种叫醣甙物质积累,这种醣甙的化合物是带苦味的,有时会在黄瓜的果实中积累,当这种醣甙在瓜内累积时,含醣量相应下降,这就使黄瓜出现苦味。在正常情况下使黄瓜变苦的醣甙是不易在瓜内累积的,但是在某种情况下,其含量会增加,以至使黄瓜出现苦味,是什么原因引起醣甙大量累积呢?从各方面的研究报导看,归纳起来大体有如下几方面原因。
Cucumber fragrance is sweet people eat vegetables. But sometimes we eat bitter cucumbers, what makes cucumber produce bitter? Analyzed by agricultural scientists, there is a kind of accumulation of glycosides, the compounds of this glycoside are bitter, and sometimes cucumber Of the fruits of accumulation, when this glycoside accumulated in the melon, the corresponding decrease in sugar content, which makes cucumber bitter taste. Under normal circumstances make glycosides cucumber bitter glycosides is not easy to accumulate in the melon, but in some cases, its content will increase, so that cucumber bitterness, what is the reason for the large accumulation of glycosides? From all aspects Research reports, summed up in general there are several reasons as follows.
