Abstract

Probiyotik bir üründen beklenen faydaların sağlanabilmesi için ürünün
raf ömrü sonuna kadar en az 10⁸-10⁹
kob/g düzeyinde canlı probiyotik mikroorganizma bulundurması gerekmektedir.
Probiyotik mikroorganizmaları olumsuz koşullara karşı korumak amacıyla çok
sayıda yöntem geliştirilmiştir. Konu ile ilgili yapılan çalışmalar, probiyotik
mikroorganizmaların canlılığını korumada en etkili yöntemlerden birinin
mikrokapsülasyon olduğunu göstermektedir. Bununla birlikte, mikrokapsülasyon
işlemi sırasında probiyotik mikroorganizmalar yüksek sıcaklık, dehidrasyon,
yüksek osmolarite gibi olumsuz koşullara maruz kalabilmektedir. Elektrohidrodinamik
atomizasyon yani elektroeğirme ve elektropüskürtme yöntemleri kullanılarak söz
konusu olumsuz koşulların üstesinden gelinebilmektedir. Son zamanlarda yapılan
çalışmalarda; yüksek voltaj altında kapsüller (elektropüskürtme) veya lifler
(elektroeğirme) üretilmesini sağlayan elektrohidrodinamik atomizasyon tekniğinin,
probiyotik mikroorganizmaların canlılıklarının korunması açısından diğer
mikrokapsülasyon yöntemlerine alternatif olabileceği belirtilmiştir. Bu derlemede, elektrohidrodinamik
atomizasyon tekniğinin temelleri ve elektropüskürtme yönteminin probiyotik
mikroorganizmaların mikrokapsülasyonunda kullanım olanakları ile ilgili bilgi
verilmesi amaçlanmıştır.

Use of Electrospray Technique in Microencapsulation of Probiotic Microorganisms

Abstract

To
provide the
expected benefits of probiotic
products, a product must contain 10⁸-10⁹cfu/g of viable probiotic microorganism
until end of the shelf life.
Numerous methods have been developed to protect
probiotic microorganisms against adverse conditions. Studies on the issue show
that microencapsulation is one of the most
efficient methods for protecting the viability of probiotic microorganisms.
However, probiotic microorganisms are exposed adverse conditions such as high
temperature, dehydration, high osmolarity etc. during the microencapsulation process. These adverse conditions can be overcome in many
cases by using electrohydrodynamic atomization (EHDA), either electrospinning
or electrospraying. Recent studies have reported that the electrohydrodynamic atomization technique, which generates the
production of capsules (electrospray) or fibers (electrospining) under high
voltage, can be an alternative to other microencapsulation methods in terms of
protecting the viability of probiotic microorganisms. In this review, it is
aimed to give information about the basics of electrohydrodynamic atomization
technique and the possibilities of using electrospray method in microencapsulation
of probiotic microorganisms.
