abstract

in this study, prodused wheyless cheese was a kind of feta cheese that was considered as a substitution for uf cheese. in this method, by mixing whey protein concentrate (wpc) or milk protein concentrate (mpc) in cream, similar to retentate, which is used in ultrafiltration cheese, was obtained. then, the process was followed similar to production of uf cheese. two experimental samples with the different whey protein / casein ratio were produced: one of the cheeses was produced by mixing wpc and mpc with the whey protein to casein ratio of 30: 70(treatment 1) and the other cheese was produced by mixing mpc with the whey protein to casein ratio of 20:80(treatment 2). then, in the produced cheeses, free amino acid profile in day 30 of ripening, textural property in day 1, 30 and 60 of ripening and sensory property in days 30 and 60 of ripening were evaluated. the concentration of free amino acids in the control cheese was significantly more than treatment 1 and 2. the results of statistical analysis of obtained data showed that the interaction of treatment and storage had significant effects on textural and sensory properties (p

improving textural and sensory characteristics of low-fat uf feta cheese made with fat replacers

saturated fat consumption increases the risk of both coronary and cancer diseases. therefore, fat reduction in uf-feta cheese (≈ 45% fdm) is favorable but, unfortunately, it has some negative effects on the texture and sensory characteristics of the cheese. in this research, response surface methodology was employed to study the probably improving effects of wpc80 (0-20 gr kg-1), lecithin (0-2 ...

Physicochemical and Amino Acid Profiling of Cheese Whey

In the current exploration, sweet liquid whey was subjected to physicochemical analysis, minerals assay and amino acid profiling. It comprised of total solids, lactose, ash, crude protein and fat as 6.49±0.31, 5.26±0.26, 0.56±0.02, 0.81±0.03 and 0.25±0.01%, respectively. The results regarding mineral analysis indicated that whey contains appreciable amount of potassium, sodium and calcium. Furt...

ripening time influence on free fatty acid and free amino acid changes of traditional kurdish cheese

traditional raw milk cheese is one of the most consuming cheeses in the world. kurdish cheese is a semi-firm, traditionally made in the east of iran. it is manufactured from raw sheep or cow milk and kept in goat’s skin bags during ripening period. as a result kurdish cheese is often more complex in different varieties of microorganisms, which whose organoleptic properties make it highly esteem...

effect of enzymatic transglutaminase treatment on textural and sensory properties of low-fat uf-feta cheese incorporated with whey proteins using response surface optimization

introduction: scientific evidence has demonstrated that consumption of high-fat foods has direct connection with increasing incidences of various diseases such as obesity, diabetes, hardening of the artery walls and blood pressure. thus, demand for low-fat foods has increasingly been promoted by health-conscious consumers. however, development of low-fat foods is challenging as fat makes a majo...
