The Use of Ultrasound Washing Process on Microbial Decontamination of Fruits and Vegetables

Öz

Microorganisms contaminated during the growing, harvesting and later stages of fruit and vegetables can sometimes cause serious health hazards. Therefore, various decontamination applications have been developed for the industrial washing of fruits and vegetables. Ultrasound technology, which is less harmful to foods in terms of physicochemical, nutritional and sensory attributes, has been evaluated and became a convenient technique in the decontamination of various foods. It is recommended the use of ultrasound technology by researchers, due to its non-harmful nature to the environment. It has been reported that disinfectants used in washing processes show higher decontamination effects when used in combination with ultrasound, therefore studies handle combined use of ultrasound and washing agents. The ultrasound technology is still in progress, and the researches about the use of ultrasound technology in the food industry continue. Considering the literature results, it is seen that ultrasound washing processes significantly reduce the initial microbial load of fruits and vegetables. For this reason, the ultrasound technology is a promising method especially in the decontamination of foodstuffs

Ultrases Yıkama İşleminin Meyve ve Sebzelerin Mikrobiyal Dekontaminasyonunda Kullanımı

Öz

Meyve ve sebzelerin yetişme, hasat ve sonrası aşamalarında bulaşan mikroorganizmalar bazen sağlık açısından ciddi tehlikeler oluşturabilmektedir. Bu sebeple meyve ve sebzelerin endüstriyel olarak yıkanmalarında çeşitli dekontaminasyon uygulamaları geliştirilmiştir. Gıdaya fizikokimyasal, besinsel ve duyusal olarak daha az zarar verdiği belirtilen ultrases teknolojisi çeşitli gıdaların yıkanmasında denenmiş ve gıdaların dekontaminasyonunda kullanılabilir bir yöntem olduğu anlaşılmıştır. Çevre açısından zararlı etki oluşturmaması nedeniyle ultrases teknolojisi araştırmacılar tarafından tavsiye edilmektedir. Yıkama işlemlerinde kullanılan dezenfektanların ultrases ile birlikte kullanıldığında daha yüksek dekontaminasyon etki gösterdikleri bildirildiğinden ultrases teknolojisinin yıkama ajanları ile bir arada kullanımı farklı araştırmalarda yer edinmektedir. Halen gelişme aşamasında olan ultrases teknolojisinin gıda endüstrisinde kullanımı ile ilgili bilimsel araştırmalar devam etmektedir. Literatür sonuçları değerlendirildiğinde, ultrases ile yıkama işlemlerinin meyve ve sebzelerin başlangıç mikrobiyal yükünü önemli oranda azalttığı görülmektedir. Bu nedenle, ultrases teknolojisi özellikle gıda maddelerinin dekontaminasyonunda gelecek vadeden bir yöntem olarak karşımıza çıkmaktadır.
