高压脉冲电场技术在食品质量与安全中的应用进展

Advances on Application of High Voltage Pulsed Electric Field in Food Quality and Safety

摘要:

高压脉冲电场技术作为国际上最先进的非热加工技术之一,以其良好的应用特性如能耗低、省时、处理温度低、效率高和对食品原有品质保存效果好等特点,吸引了国内外广大研究者的关注。与其它食品加工技术相比,高压脉冲电场技术不仅具有更好的杀菌、钝酶效果,还能有效降解残留农药,减少食品添加剂的使用,而且基本不影响食品的原有品质和营养特性。因此,将高压脉冲电场技术有效应用于食品工业中,可大大提高食品质量与食品安全性,为食品行业的发展开辟新途径。作者介绍了高压脉冲电场的处理装置、加工机理以及在食品质量与安全中的应用途径,并对高压脉冲电场技术的应用前景进行了展望。

Abstract:

As one of the most advanced athermal treatment technologies,high voltage pulsed electric field(HPEF) technology has attracted the attention of the researchers in the world with its good application properties,such as low energy consumption,time saving,low treatment temperature,high efficiency and good preservation effect for the quality of original food.Compared with other processing technologies,HPEF technology not only shows better effect of sterilization and of blunting enzymes,but also degrades pesticide residues effectively,decreases additives use,and hardly affects the original quality and nutritional characteristics of the treated food.Therefore,application of HPEF technology in food industry will greatly improve food quality and safety,and provide a new way for the development of food industry.Processing device,treatment mechanisms of HPEF technology and its possible application ways for food quality and safety control have been introduced in this review,and its advances on application in food quality and safety envisaged.
