| 摘 要： | 清洗是蔬菜加工的关键环节,对品质至关重要.采用自行研制的超声及气泡式清洗设备对消费量较大的叶类蔬菜(生菜)进行清洗,以洗净率和破损率为指标,对清洗效果进行评价.结果表明,气泡式清洗在清洗时间40 s,洗菜量500 g条件下,生菜洗净率达到100％,此时破损率为12.89％;采用超声清洗时,在频率68 kHz,功率900 W,时间40 s,洗菜量750 g条件下,生菜洗净率为100％时,破损率为9.62％.可见当清洗时间相同,洗净率均达到100％时,超声清洗方式的洗菜量增加50％,破损率降低25.4％.因此,超声清洗方式更具优势.

| Abstract: | Cleaning is one of the key link in vegetables processing, which is vital for the quality. In this paper, the self-developed ultrasound and air-bubble washing devices were employed to wash a widely consumed leafy vegetable(lettuce), and then the cleaning effects were evaluated using cleaning ratio and damage ratio as indicators. Results indicated that cleaning ratio of lettuces reached to 100% with a damage ratio of 12.89% using air-bubble cleaning technology under the following conditions: washing time of 40 s and lettuces weight of 500 g. While the cleaning ratio of lettuces reached to 100% with a damage ratio of 9.62% when lettuces of 750 g was washed with the ultrasonic cleaning device under the ultrasonic frequency of 68 kHz, ultrasonic power of 900 W and washing time of 40 s. These data demonstrated that the washing amount was increased by 50% while the damage ratio was reduced by 25.4% when lettuces were washed using ultrasonic cleaning technology under the same washing time and cleaning ratio. Therefore, ultrasonic cleaning technology displayed superior advantages. |
