摘要
以"桂蕉6号"香蕉果实为对象,研究两种贮藏温度对其糖酸组分的影响。采用高效液相色谱法(HPLC)测定香蕉在室温(25℃)与低温(15℃)两种贮藏温度条件下糖酸组分含量的差异性。结果表明:贮藏温度显著影响(p<0.05)香蕉果实的蔗糖、葡萄糖、果糖、总糖、柠檬酸、总酸含量;在室温和低温贮藏条件下,其糖组分含量变化幅度较大,蔗糖增长幅度分别为74.66%、35.952%,葡萄糖增长幅度分别为62.30%、36.54%,果糖增长幅度分别为83.22%、57.65%,总糖增长幅度分别为73.731%、39.440%,而其有机酸组分及含量的变化相对缓和;在不同贮藏温度下,香蕉果实的糖酸组分含量存在一定差异,与室温贮藏相比,低温贮藏能有效抑制糖组分的增长速度。
The effects of two different storage temperatures on sugar and acid compositions were studied using cv."Guijiao No.6" banana fruits as materials.Compositions and contents of sugars and acids in banana fruits stored at room temperature( 25 ℃ ) and low temperature( 15 ℃ )were investigated by high performance liquid chromatography (HPLC).The results showed that storing temperature significantly affected sucrose, glucose, fructose, total sugars, citric acid and total acids (p 〈 0.05 ).At 25 and 15℃ storage condition, there were large variations in the sugar component content.The sucrose, glucose, fructose, total sugar increased by 74.66% , 62.30%, 83.22%, 73.731% and 35.952%, 36.54%, 57.65%, 39.440%, respectively. But the changes in concentrations of organic acid components were no significant.The compositions and contents of sugars and acids in banana fruits presented difference during storage at different temperatures.In comparison of room temperature, low temperature significantly inhibited the decreases of sugar compositions and contents.
