Production optimization of probiotic soft cheese made from goat\u27s and cow\u27s milk

Svrha ovog rada bila je definirati optimalnu količinu dodanog sirila te udjel mliječne masti za proizvodnju probiotičkog svježeg sira od kozjeg mlijeka, upotrebom mješovite DVS ABT-4 kulture (Lactobacillus acidophilus, Bifidobacterium spp. i Streptococcus thermophilus), koji će posjedovati poželjna senzorska svojstva, prihvatljiva potrošaču. Najbolje senzorske ocjene imali su uzorci probiotičkog svježeg sira proizvedeni u laboratorijskim uvjetima od mlijeka s 1% mliječne masti, pasteriziranog dugotrajnom niskom pasterizacijom (65°C/30 min.), fermentiranog na 38°C uz dodatak 2% kulture. Da bi se postigla karakteristična konzistencija tradicionalnog svježeg sira, u kozje mlijeko bilo je potrebno dodati i 0,01% sirila. Probiotički svježi sirevi od kozjeg mlijeka - kao i od kravljeg - proizvedeni uz optimalne uvjete, bili su 100% prihvatljivi od testiranih potrošača.The aim of this study was to determine optimal rennet share and fat content in milk for probiotic soft cheeseproduction made from goat\u27s and cow\u27s milk using DVS mixed probiotic culture ABT-4 (Lactobacillus acidophilus, Bifidobacterium spp. and Streptococcus thermophilus), with desirable sensory properties, which will be acceptable by consumers. The best sensory scores had samples of probiotic soft cheese produced in laboratory conditions from milk with 1% of milk fat, pasteurized at 65°C/30 min., fermented at 38°C with 2% culture. To achieve characteristic consistency of traditional soft cheese, 0.01% of rennet was added to goat\u27s milk. Probiotic soft cheese made from cow\u27s and goat\u27s milk, produced under optimal conditions, were 100% acceptable by the tested consumers
