Brynza occupies an important place among cheeses in Ukraine. is a highly concentrated polydisperse system, the features of which are determined by size particles dispersed phase. It has white (close to white) color, uniform throughout mass. The taste and smell cottage cheese sour-milk, moderately salty. Physicochemical, biochemical microbiological processes their intensity depend on concentrati...

The use of freeze-dried kefir coculture as a starter in the production of feta-type cheese was investigated. Maturation of the produced cheese at 4 degrees C was monitored for up to 70 days, and the effects of the starter culture, the salting method, and the ripening process on quality characteristics were studied. The use of kefir coculture as a starter led to increased lactic acid concentrati...

Ricotta fresca cheese is the product of Sardinian dairy industry most exposed to microbial post-process contamination. Due to its technological characteristics, intrinsic parameters, pH (6.10-6.80) and water activity (0.974-0.991), it represents an excellent substrate for the growth of spoilage and pathogenic microorganisms, which are usually resident in cheese-making plants environments. Gener...

the objective of this study was to identify acinetobacter in a traditional cheese from west azarbaijan, iran, and to study the lipolytic and proteolytic activities of these bacteria in ripening of white brine cheese. acinetobacter is a gram negative bacteria which can be found in different sources as dairy products. lypolysis and proteolysis characteristic of this bacteria and thus its role in ...

BACKGROUND Aflatoxin M₁ (AFM₁) is the main monohydroxylated derivative of aflatoxin B₁ (AFB₁) formed in liver and excreted into milk. Although AFM₁ is less toxic than AFB₁, it has been classified as a possible human carcinogen, Group 2B agent by International Agency for Research on Cancer (IARC). OBJECTIVES The objectives of this study were (i) to determine the occurrence of AFM₁ in the main ...

Volatile sulfur compounds such as methanethiol, dimethyl disulfide, dimethyl trisulfide, and hydrogen sulfide constitute an important fraction of Cheddar cheese flavor. These compounds are products of the catabolism of methionine and cysteine by bacteria in the cheese matrix. The objectives of this study were to examine the levels and types of volatile sulfur compounds produced from methionine ...

Transgenic cows secreting over 3 microg of lysostaphin/ mL of milk are protected against mastitis caused by Staphylococcus aureus, but it is unknown if active lysostaphin persists through dairy processing procedures or affects the production of fermented dairy foods. The objective of this study was to determine the fate of lysostaphin as milk was pasteurized and then processed into cheese. Raw ...

In this research, food (cheese, yoghurt) and animal (chicken) origin 39 Lactobacillus spp. human (newborn faeces) three Bifidobacterium were used. To designate the β-glycosidase enzyme specific activities of cultures, p-nitrophenyl-β-D glikopiranozit (p-NPG) was used as a substrate. The best between Lactobacilli cultures observed at rhamnosus BAZ78 (4.500 U/mg), L. SMP6-5 (2.670 casei LB65 (3.0...
