氯吡脲（CPPU）作为植物生长调节剂，被广泛应用于果蔬增产。研究了超声法降解模型猕猴桃汁中的CPPU。结果表明，水浴超声能有效去除模型猕猴桃汁中的CPPU，超声功率、超声时间和超声温度对模型猕猴桃汁中磷酸盐的降解有显著影响（p < 0.05）。经600 W、45℃、40 min超声处理后，降解率达到72.01%。通过响应面二次模型方差分析，超声处理关键因素的主次顺序为温度b>处理时间b>功率。通过UPCL-Q-TOF-MS鉴定出3-hydroxyphenyl-forchlorfenuron和4-hydroxyphenyl-forchlorfenuron是CPPU的降解产物。猕猴桃因其良好的口感、风味和丰富的营养价值而在世界各地广泛种植。氯吡脲（1-（2-氯-4-吡啶基）-3-苯脲）是猕猴桃栽培和保护中应用最广泛的植物生长调节剂。超声波处理可以有效地降解PGR残留物，并在很大程度上保留了产品的感官和营养品质。与其他热处理方法相比，对氯吡脲进行超声波处理可能具有更好的去除效果。因此，超声波技术作为一种操作简单、成本低的处理技术，在猕猴桃果汁中氯虫腈残留和其他PGR残留的处理中具有商业应用价值。化学品目录编号氯吡脲（纯度bbb99 %） （PubChem CID: 93379）；n -丙基乙二胺（PubChem CID: 15659）；柠檬酸（PubChem CID: 311）；柠檬酸三钠（PubChem CID: 6224）；糖（PubChem CID: 5988）；盐酸（PubChem CID: 313）；乙腈（PubChem CID: 6342）；冰醋酸（PubChem CID: 176）；无水硫酸镁（PubChem CID: 24083）；无水醋酸钠（PubChem CID: 517045）。
Forchlorfenuron (CPPU), as a plant growth regulator, is widely applied to promote fruits and vegetables yield. The degradation of CPPU in model kiwifruit juice by sonication was investigated in the present study. Results showed that bath sonication was effective in eliminating CPPU in model kiwifruit juice, and the ultrasonic power, time and temperature significantly influenced the degradation of phorate (p < .05). The maximum degradations were achieved 72.01% after the ultrasonic treatment at 600 W, 45 degrees C for 40 min. The primary and secondary factor order of the key factors of ultrasonic treatment was temperature > treatment time > power through analysis of variance for response surface quadratic model. Furthermore, 3-hydroxyphenyl-forchlorfenuron and 4-hydroxyphenyl-forchlorfenuron were identified as the degradation products of CPPU by UPCL-Q-TOF-MS.Practical applications Kiwifruit had grown throughout the world owing to its good taste, flavor, and significant nutritional. Forchlorfenuron (1-(2-chloro-4-pyridyl)-3-phenylurea) is the most widely used plant growth regulators (PGR) for kiwifruit cultivation and protection. Ultrasonic treatment may effectively degrade PGR residues and mostly retain the sensory and nutritional quality of the product. Compared to other thermal treatments, forchlorfenuron subjected to ultrasonic treatment maybe show better removal efficiency. Thus, as an easy operation and low-cost processing technology, ultrasonic technique may be commercially useful to develop forchlorfenuron residues in Kiwifruit juice and other PGR residues.Catalogue Number of Chemicals Forchlorfenuron (purity > 99%) (PubChem CID: 93379); N-propyl Ethylenediamine (PubChem CID: 15659); Citric Acid (PubChem CID: 311); Trisodium Citrate (PubChem CID: 6224); Saccharose (PubChem CID: 5988); Hydrochloric Acid (PubChem CID: 313); Acetonitrile (PubChem CID: 6342); Glacial Acetic Acid (PubChem CID: 176); Anhydrous Magnesium Sulfate (PubChem CID: 24083); Anhydrous Sodium Acetate (PubChem CID: 517045).
