In this research, some microbiological and physicochemical properties of milk powder produced by freeze dryer and spray dryer were determined during the storage period. Firstly, milks were divided into two groups. First group was dryed with freeze dryer. Second group was dryed with spray dryer. Total aerobic mesophilic bacteria, mould-yeast, total coliform and fecal coliform, moisture, hunter colour determination, water activity, pH analyses were performed in 2., 4. and 6. days of storage at room temperatures. Water absorption index, water solubility index, protein and microscopy analysis was performed in 2.day, 6.day and 6.day of storage, respectively. Moisture, water activity, microbiological analysis, L value and water absorption index values of freeze dryed milk powders were found lower than spray dryed samples in all days of storage. Microbiological quality of freeze dryed milk powder is better. It was thaught that the milk powder produced by freeze drying may have a longer shelf life at room temperature.

Bu çalışmada dondurularak ve püskürterek kurutulan süt tozlarının bazı mikrobiyolojik ve fizikokimyasal özellikleri depolama süresi boyunca araştırılmıştır. İlk olarak sütler iki gruba ayrılmıştır. İlk grup süt dondurarak kurutucu ile;ikinci grup ise püskürtmeli kurutucu ile kurutulmuştur. Oda sıcaklığında, depolamanın 2., 4.ve 6.günlerinde toplam aerofilik mezofilik bakteri, maya-küf, toplam koliform ve fekal koliform, nem, hunter renk analizi, su aktivitesi, pH analizleri yapılmıştır. Su absorplama indeksi, suda çözünme indeksi, protein ve mikroskopik analizler depolamanın sırasıyla 2., 6.ve 6.günlerinde gerçekleştirilmiştir. Dondurarak kurutma ile üretilen örneklerin nem, su aktivitesi, mikrobiyolojik analiz, L değeri ve su absorplama indeksi sonuçları bütün depolama günleri için püskürterek kurutma ile üretilen örneklerin değerlerinden daha düşük olarak bulunmuştur. Dondurarak kurutulan örneklerin mikrobiyolojik kalitesinin daha iyi olduğu saptanmıştır. Elde edilen sonuçlar düşünüldüğünde dondurarak kurutma ile üretilen süt tozlarının oda sıcaklığında daha uzun raf ömrüne sahip olabileceği düşünülmüştür.
