| 摘 要： | 新疆特色农产品绿葡萄干由晾房阴干而制得,针对其存在不易水洗和安全品质低的问题,本文采用乙醇-超声波清洗方法,研究清洗次数、超声温度、超声时间、超声频率、液料比、乙醇浓度对无核白葡萄干清洗和杀菌效果的影响。结果表明:在室温,85%乙醇,液料比1.5∶1(mL/g),超声频率40 kHz,清洗2次,每次超声1 min的条件下,无核白葡萄干清洗效果理想,糖溶出较少,且杀菌率高。

| Abstract: | The green raisin, a kind of Xinjiang characteristic agricultural products is dried in the shade in a special ventilated ‘dry room’. Thus there are problems such as difficult washing, low hygiene and safety quality. This paper used ethanol-ultrasonic cleaning technique, and discussed the effects of cleaning frequency, ultrasonic temperature,ultrasonic time, ultrasonic frequency, liquid-material ratio and ethanol concentration on the cleaning and germicidal efficacy of the thompson seedless raisins. The results showed that, the best cleaning technique was as follows:room temperature, ethanol concentrations 85%, liquid-material ratio 1.5∶1(mL/g), ultrasonic frequency 40 kHz,cleaning frequency 2 times and ultrasonic frequency 1 min/time, under these conditions, the cleaning effect of thompson seedless raisins was ideal, with less sugar dissolved and higher sterilization efficacy. |
