In this paper, influence of the composition of autohtonous Sjenica cheese and composition of cheese made from cow milk in the type of Sjenica cheese were comparatively investigated. Autohtonous Sjenica cheese, made from ewe's milk and Sjenica type cheese made from cow's milk both had high content of moisture (53.46% and 59.56% respectively), which is the result of production process (coagulation time, curd processing, drying and salting). According to moisture content in fat free basis - MFFB (73.51% and 73.38% respectively) both cheeses belong to soft cheeses group, and according to fat in total solids - FTS (58.66% and 46.75% respectively) they belong to a group of whole milk cheeses. Ripening coefficient of Sjenica cheese made from ewe's milk (21.42%) was larger than ripening coefficient of Sjenica type cheese made from cow's milk (20.41%). Big differences in chemical composition of both cheeses are due to non-uniformly technology, which imposes need to assimilate technology process of Sjenica cheese production and fulfill geographic origin protection of Sjenica cheese as autohthonous cheese characteristic for wider area of Sjenicko-pesterska plateau.

There were cheeses produced from raw cow’s milk and from mixed milk compared. Mixed milk contained small ruminants’ milk (goat’s and ewe’s milk) and cow’s milk in different proportions. There were technological, physical and health parameters, mineral composition, microbiological indicators and sensory quality evaluated. Cow’s milk, compared to mixed milk, contained markedly lower amounts of fat, protein, casein, total solids, solids non fat, urea and acetone and higher values of lactose, citric acid and free fatty acids and showed significantly lower values of somatic cell count. Mixed milk showed lower (better) results for freezing point depression, markedly higher titration acidity and higher values ​​for Ca, Mg, K, P, Cu, Mn and Zn. The results of microbiological analyses confirmed good hygienic quality in terms of total count of mesophlic, psychrotrophic and thermoresistant bacteria and coliforms. Negative incidence ofL. monocytogenesand mostly negative incidence ofS. aureusare important results and confirmed high quality of raw material for cheese production. None ofS. aureusstrains were confirmed as MRSA. The results of sensory evaluation showed no significant differences between cheeses originated from cow’s milk and cheeses from mixed milk.

Buffalo milk mozzarella is often adulterated by the addition of cow’s milk. The aim of this study was to assess the quality of buffalo milk mozzarella by using electrophoresis (SDS-PAGE) to detect the addition of cow’s milk. Reference cheeses were produced exclusively from combinations of buffalo and cow milk, and labeled reference treatment buffalo or cow (RTB and RTC, respectively). Standardized cheeses were made by combining buffalo milk and 2.5%, 5.0%, 10%, 20%, 30%, 40% or 50% cow’s milk. A total of 9 cheese formulations were produced and either frozen immediately (time 0) or after 20 days (time 20). Eighteen commercial samples of buffalo mozzarella were sampled between 0–20 days of production. The chemical composition (moisture, ash, fat in dry matter, protein, total solids and defatted dry extract) and physicochemical characteristics (acidity) of the cheeses were evaluated. Proteins and water-soluble peptides (WSP) extracted from RTB, RTC and from the commercial samples, and were analyzed by SDS-PAGE electrophoresis under denaturing conditions. It was not possible to detect the inclusion of cow’s milk by the cheeses’ chemical and physicochemical properties. However, the separation and detection of peptide and protein fractions of the cheese was possible by electrophoresis. The results of the electrophoretic analysis suggest that 28% of the commercial samples considered here had evidence of the addition of cow’s milk. The methodology described here is important to identify occurrences of fraud in buffalo mozzarella production.

Cattle waste contains high enough Escherichia coli microbes that can contaminate dairy products. Contamination can come from various sources of cow udder, cow body, dust in the air, dirty equipment and humans who do milking. Hygiene and sanitation efforts are one of the most important environmental health efforts to prevent dairy contamination. This study aims to analyzed the relationship of hygiene breeders, sanitation cage and bacteriological quality of cow milk (Escherichia coli) in Krajan Hamlet, Gendro Village, Tutur District, Pasuruan Regency. This research was conducted with cross sectional design. The sample size used was the total population of 26 farmers registered to be members of the group of Agung II breeders in Krajan Hamlet. Breeder hygiene and cage sanitation were analyzed descriptively quantitatively on bacteriological quality of cow's milk (Escherichia coli). Breeder hygiene includes 3 components: the use of PPE when working (boots, masks, gloves), hand-washing habits and work clothing conditions. Cage sanitation includes 5 components namely the technical requirements of the cage building, the location of the cage, the direction of the cage, the handling of livestock waste, the cleanliness of the cage. Bacteriological qualities of cow's milk (Escherichia coli) were examined in the laboratory using isolation and identification techniques. As many as 73% of respondents included in the category of poor farmer's hygiene and 65% of respondents included in the category of poor cage sanitation. While the examination of milk samples as much as 65% is known to be contaminat Escherichia coli. Increas use of PPE (Personal Protective Equipment) and cage sanitation management needs to be done by farmers to prevent contamination of Escherichia coli in dairy products.

Kefir is one of the fermented beverages which has a distinctive taste from other fermented milk products. Based on the results of several studies concluded that one that affects the quality of kefir is the milk of being used for. The purpose of this study was to examine the comparison of physiochemical quality of kefir made from goat’s milk and cow’s milk. This study used Completely Randomized Design (CRD) with two treatments and five replications using different milk which was goat’s milk and cow’s milk. Parameters measured were the weight gain of kefir grain (PBBK), ethanol content, the percentage of lactic acid and pH of kefir. The data obtained were analyzed by using the Analysis of Variance and if the treatment was significantly different, then the test continued with the Least Significant Difference (LSD). The results showed that kefir produced with different types of milk showed a significant effect (P <0.05) on pH parameters, lactic acid percentage, and ethanol content, but no significant effect (P>0.05) on the value of PBBK. It can be concluded that the best kefir made of goat milk has characteristics: pH value 3.89, the percentage of lactic acid 0.14; PBBK 26.61%; and 0.72% ethanol content.

AbstractThe current study measured the influence of milk of subclinically infected glands by different bacteria species on the cow’s milk and suggests different parameters for milk payment. The effects of bacterial infection or inflammation on gland milk yield were related to the bacteria species that caused the infection. The volume of milk of the inflamed gland from the cow’s milk yield was significantly lower (P<0.001) for the glands previously infected byEscherichia coli(PIEc) and those infected withStreptococcus dysgalactiae.Coagulation properties, rennet clotting time (RCT) and curd firmness (CF) also depended on the bacteria causing the infection. RCT values of all the inflamed glands were significantly longer (P<0.001) and CF values were significantly lower than that of the healthy ones. Moreover, in the whole milk, CF was also significantly lower and not proportional to the volume of the milk from the inflamed gland of the cow’s milk. Calculating the predicted 40% dry matter curd weight (PCW) on the cow level, including the healthy and inflamed glands or the healthy glands alone, found that for 9 of 13 PIEc cows, the presence of the affected gland’s milk in the whole cow milk resulted in a negative PCW value. Likewise, 5 of 20 cows infected byS. dysgalactiaehad negative delta values. Unlike the latter bacteria, PCW from milk of glands infected with CNS increased, although in a lower magnitude than in the healthy glands. No correlation was found between logSCC in the whole cow milk (healthy and inflamed glands) and PCW.

A new type of cow’s milk, called A2 milk, has appeared in the dairy aisles of supermarkets in recent years. Cows’ milk generally contains two major types of beta-casein as A1 and A2 types, although there are 13 genetic variants of β-casein: A1, A2, A3, A4, B, C, D, E, F, H1, H2, I and G. Studies have shown that A1 β-casein may be harmful, and A2 β-casein is a safer choice for human health especially in infant nutrition and health. The A2 cow milk is reportedly easier to digest and better absorb than A1 or other types of milk. The structure of A2 cow’s milk protein is more comparable to human breast milk, as well as milk from goats, sheep and buffalo. Digestion of A1 type milk produces a peptide called β-casomorphin-7 (BCM-7), which is implicated with adverse gastrointestinal effects on milk consumption. In addition, bovine milk contains predominantly αs1-casein and low levels or even absent in αs2-casein, whereby caprine milk has been recommended as an ideal substitute for patients suffering from allergies against cow milk protein or other food sources. Since goat milk contains relatively low levels of αs1-casein or negligible its content, and αs2-casein levels are high in the milk of most dairy goat breeds, it is logical to assume that children with a high milk sensitivity to αs1-casein should tolerate goat milk well. Cow milk protein allergy (CMPA) is considered a common milk digestive and metabolic disorder or allergic disease with various levels of prevalence from 2.5% in children during the first 3 years of life to 12–30% in infants less than 3 months old, and it can go up to even as high as 20% in some countries. CMPA is an IgE-mediated allergy where the body starts to produce IgE antibodies against certain protein (allergens) such as A1 milk and αs1-casein in bovine milk. Studies have shown that ingestion of β-casein A1 milk can cause ischemic heart disease, type-1 diabetes, arteriosclerosis, sudden infant death syndrome, autism, schizophrenia, etc. The knowledge of bovine A2 milk and caprine αs2-casein has been utilized to rescue CMPA patients and other potential disease problems. This knowledge has been genetically applied to milk production in cows or goats or even whole herds of the two species. This practice has happened in California and Ohio, as well as in New Zealand, where this A2 cow milk has been now advanced commercially. In the USA, there have been even promotions of bulls, whose daughters have been tested homozygous for the A2 β-casein protein.

SummaryGeneration times and acid production after 6 and 24 h by 20 strains ofStreptococcus lactisof dairy origin were determined in heat treated (80 °C for 30 min) and sterilized cow's and ewe's milk. Ewe's milk enhanced growth of the streptococci, with significantly (P< 0·001) shorter generation times and higher acid production after 6 h incubation than cow's milk, probably due to its higher vitamin content. The stronger buffer capacity of ewe's milk allowed a higher (P< 0·001) acid production after 24 h than cow's milk. A stimulatory effect of sterilization on generation time and acid production after 24 h was observed in cow's milk. However, the heat treated ewe's milk was shown to be a better substrate than sterilized ewe's milk forStr. lactis.

The alkaline phosphatase (ALP) activity test has been used since 1935 to assess the effectiveness of pasteurization. Different analytical methods exist for detecting ALP in milk. Unfortunately, there is little information about ALP activity in ewe's milk. The aim of this study was to assess and compare the official European method (spectrophotometric method) and the Fluorophos method (fluorometric method) regarding their use in ewe's milk. Bulk ewe's milk samples were taken from a flock and from three different dairies. A portion of the original sample was pasteurized at 63°C for 30 min in a circulating bath; another portion was heated to and kept at 95°C for about 2 min, and 0.1% (vol/vol) of raw milk was added. The samples obtained were analyzed in duplicate using the spectrophotometric and fluorometric methods. The relation between ALP activity determined by the two methods was characterized by the following equation: Y = 1.34 + 0.0039X (where Y = ALP in μg of phenol per ml of milk and X = ALP in mU/liter; R2 = 91.5%). Precision parameters (repeatability [r], standard deviation of repeatability [sr], and relative standard deviation of repeatability [RSDr]) for both methods were calculated. The values of RSDr for the Fluorophos method were 4.30 for pasteurized milk and 2.96 for 0.1% raw milk, close to the value indicated by Rocco in whole cow's milk (RSDr = 4.4). The repeatability for the official method (r = 2.16) was close to that indicated for whole cow's milk (r = 2).
