Abstract

Bu çalışmada
farklı kaplama materyalleri ile kaplanmış Lactobacillus
rhamnosus'un farklı sıcaklık ve sürelerdeki termal inaktivasyon
kinetiklerinin belirlenmesi amaçlanmıştır. Bu çalışmada probiyotik kültür
olarak L. rhamnosus kullanılmış ve
farklı kombinasyonlardaki kaplama materyalleri ile (aljinat, jelatin ve gellan
gam) ekstrüzyon tekniğine göre kaplanmıştır. Mikroenkapsüle L. rhamnosus'un 55-60 ^oC'de
15 ve 30 dakikalık ısıl işlemdeki sıcaklık dayanımları serbest kültür ile
kıyaslanmıştır. Elde edilen sonuçlara göre mikroenkapsüle kültürlerin sıcaklık
dayanımlarının serbest kültürlere göre daha iyi olduğu bulunmuştur. Ayrıca
kaplama materyali kombinasyonunun hücrelerin canlılıkları üzerinde etkili
olduğu saptanmıştır.
