摘要
食品在生产和消费环节极易受到微生物污染,严重影响其安全性和品质。紫外发光二极管(Ultraviolet Light-emitting Diodes,UV-LEDs)作为传统紫外汞灯的替代光源,具有波长可调、绿色环保、安全高效等优点。对该技术在食品杀菌保鲜领域的应用、其对食品品质的影响及与其他非热杀菌技术协同杀菌的应用研究进行了综述,认为:UV-LEDs技术不仅能够有效杀灭食源性致病菌和腐败菌,而且可以较好地保持食品品质,将其与微酸性电解水、Cl_(2)、超声波等协同使用,可进一步增强其杀菌效果。然而,该技术在应用过程中存在穿透力弱、处理量小等问题,今后应在处理工艺参数优化和装置方面进行深入研究,以期为UV-LEDs技术在食品安全控制领域中的实际应用提供参考。
Food is easily contaminated by microorganism during production and consumption, which causes serious adverse effect on its safety and quality.As an alternative source of traditional ultraviolet mercury lamp, ultraviolet light-emitting diodes(UV-LEDs) have many advantages, such as adjustable wavelength, environmentally friendly, safe and efficient.This paper aimed to review the application of UV-LEDs in the field of food sterilization and preservation, its influence on food quality and its application progress in collaboration with other non-thermal sterilization technologies.The results indicated that UV-LEDS could not only effectively sterilize foodborne pathogenic bacteria and spoilage bacteria, but also could well maintain the quality of food products.The bactericidal effect could be further enhanced when it is used in combination with other technologies such as slightly acidic electrolytic water, Cl_(2) and ultrasound. However, UV-LEDs have some disadvantages, such as weak penetration and small processing capacity.More attention should be paid to the optimization of processing parameters and equipment development in the future.This paper provides reference for the practical application of UV-LEDs in the field of food safety control.
