Abstract

Drum dryer was used for the production of powders from carrot and pumpkin juice. After the pretreatments, the vegetables were processed into juice, and then drying was performed by a drum dryer with 2 cylinders at 3 bar pressurized vapour. Drum-dried products (flakes) were ground into a powder form by a grinder. Powders were reconstituted to the same °Brix value with the vegetable juices and compared for the quality characteristics such as pH, moisture content, acidity, color, total and invert sugar, total phenolic content, total carotenoids, turbidity, pulp ratio and serum separation. Drying process increased phenolic contents but caused some quality losses such as total carotenoids, soluble solids and a decrease in lightness (CIE L*) value

Özet

Havuç suyu tozu ve balkabağı suyu tozunun üretildiği bu çalışmada valsli kurutucu ile çalışılmıştır. Hammaddelere uygulanan ön işlemlerin ardından, sebze suyu eldesi sonrasında kurutma işlemi 3 bar basınçlı buharla ısıtılan, iki silindirli valsli kurutucuda gerçekleştirilmiş ve pulcuklar halinde alınan ara ürün, öğütülerek toz haline getirilmiştir. Toz örnekler, sebze suları ile aynı kuru madde değerine sulandırılarak pulplu sebze suları elde edilmiştir. Toz üründen elde edilen bu örneklerin kalite özellikleri, sebze suları ile kıyaslanmıştır. Yapılan pH, nem, titrasyon asitliği, renk, toplam ve indirgen şeker, toplam fenolik madde ve karotenoit madde miktarı, bulanıklık, pulp oranı ve serum ayrılması analizlerinde saptanan sonuçlar karşılaştırılmıştır. Kurutma işleminin toplam fenolik madde miktarında artış sağladığı, toplam karotenoitlerde kayba, parlaklıkta (CIE L*) azalmaya neden olduğu belirlenmiştir
