【摘要】 采用高效液相色谱法(HPLC)进行定量分析,研究了加热温度和加热时间对胡柚汁中柚皮苷含量的影响。试验结果表明:加热时间一定,随着加热温度的升高,柚皮苷含量呈总体上升趋势,在75～90℃之间变化明显。时间试验中,加热15min时,胡柚汁中的柚皮苷含量达到最大值。优化试验显示,加热时间是影响胡柚汁热加工中柚皮苷变化的主要因素,加热温度次之,采用高温度短时间的热处理方式有利于控制胡柚汁中柚皮苷的含量。更多还原

【Abstract】 The quantitative analysis was done by HPLC method,the research is about the effect of heating temperature and time on the content of naringin in grapefruit juice.Experiment results indicate that while the heating time is the same,the content of naringin increased with the rise of temperature,and it has a significantly increasing trend during 75 ℃ and 90 ℃.In the MSTL,when the heating time reaching to 15 min,the content of naringin maximizing.The EVOP shows that heating time is the major factor which affects the change of naringin in grapefruit juice during its processing,followed by heating temperature,the application of high temperature and short time dispose model is good for controlling the content of naringin in grapefruit juice.更多还原
