Abstract In the study, the microencapsulation method was applied in the production of white cheese from goat milk to prevent the loss of viability of Lactobacillus paracasei and Bifidobacterium longum due to environmental factors during their storage period. For this purpose, the cheese was obtained using three types of microcapsules - symbiotic microcapsules containing probiotic bacteria and probiotic + fructooligosaccharide, probiotic + inulin. In addition, probiotics, fructooligosaccharide and inulin have been added to cheese in free form, and a total of 7 different cheeses have been produced with the control sample. In the microencapsulation, 1% sodium alginate was used as coating material and the extrusion method was applied. The cheese samples have been stored at +4 0C for 180 days. It has been determined that the viability of L. paracasei and B.longum has been preserved with the microencapsulation technique, while the viability of probiotic bacteria is preserved at a higher level in cheese samples obtained with the addition of prebiotics to microencapsules. It has been concluded that probiotic microorganisms are available above the minimum therapeutic effect value in grams of cheese samples containing microcapsules and these cheese could be considered as probiotic.

Abstract The method of microencapsulation has been performed on the probiotic microorganisms (Lactobacillus paracasei and Bifidobacterium longum), which are used in conjunction with the starter cultures in white cheese production from goat‘s milk. For this purpose, 3 types of microcapsules, namely, one containing the probiotic bacteria and another symbiotic microcapsule containing the probiotic bacteria and fructooligosaccharides have been obtained in the study and the cheese containing these microcapsules were produced. The cheese samples have been stored at +40C for 180 days and during storage, loss in viabiality that might be consisted at in-vitro conditions at gastrointestinal system is analyzed. The present study revealed that probiotic bacteria at different bile concentrations gained resistance during maturation, and the rate of resistance was higher in prebiotic and protein-supported microencapsulated probiotic bacteria. The resistance of lactic acid bacteria used in cheese production to gastric secretions was lower than that of probiotic bacteria. The determination of hydrophobicity of bacteria revealed that Bifidobacterium longum had the highest hydrophobicity level followed by Lactococcus, which forms the cheese culture, while Lactobacillus paracasei had the lowest level. It was determined that the microencapsulation method reduced the viability losses of probiotic microorganisms in the gastrointestinal tract.

Abstract In this study, the effects of edible film (EWPPCVV) produced by the addition (2% v/v) orange essential oil (EOCVV) to sorbitol (3% w/v) egg white protein powder (EWPP) based film on the physico-chemical and antibacterial properties, appearance (color, structure, brightness) and odor of kashar cheese were studied .Cheese samples were separately coated with these films and stored at +4°C for 30 days. Analyses were performed on the 1st, 7th, 15th and the 30th days of storage. During storage, the inner and outer hardness values during storage of the samples coated with EWPPCVV were lower than of those coated with EWPP. With the addition of EOCVV to the film, the antimicrobial effects on of the studied microorganisms increased. EWPP film was brighter and more transparent compared to EWPPCVV. The color of EWPPCVV was more yellowish.
