Oštiepok is a traditional half-fat semi-hard cheese made in Slovakia. The basic raw material used to produce oštiepok cheese is ewe's milk, a mixture of ewe's and cow's milk or cow's milk. Oštiepok cheese is produced either directly at a small-scale mountainside sheep farm, using the traditional on-farm method of production, or at dairies, using the industrial method. Oštiepok cheese was produced as far back as the beginning of the 18th century. An industrial production of Oštiepok cheese using cow's milk were laid by the Galbavý family in Detva (Slovakia) in 1921. The cheese is originally made by cutting off fresh sweet cheese, which is pressed into a wooden, hand-cut and decorated round shape where it is left to stand. Subsequently, it is removed and immersed in warm salty water, left to stand there until the salt penetrates completely in. Then it is necessary that it pass slightly. In its salty water, the ostrich produces its traditional durability, its surface is slightly peeled, mostly yellowish. This cheese may or may not be steamed and may be smoked or unsmoked. Slovenský oštiepok is a protected trade name under the EU's protected geographical indication. A similar cheese is made in the Polish Tatra Mountains under the name Oscypek. The cheeses differ in ingredients' ratios, cheesemaking process and the characteristics of the final products. In this study we have characterized textural and sensory properties of the Oštiepok cheese produced in Slovakia made from ewe's milk, a mixture of ewe's and cow's milk and cow's milk.

Cheese Production

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.

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.

European Method

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).

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.

The article presents the results of studies obtained in the study of the quality of milk processed with the use of high-frequency acoustic cavitation and dairy products produced with its use. The research was carried out with the use of General scientific and special research methods in the laboratory of the Department of technology of storage and processing of animal products of the K. A. Timiryazev and in the accredited laboratory of technochemical control of the all-Russian research Institute of dairy industry. It is shown that the treatment of cow's milk-raw materials high-frequency ultrasonic vibrations (above 45 kHz), the generated electric ultrasonic device immersion type pulse impact ouzo "Activator-150", the number of bacteria of group of intestinal sticks (coliforms) decreased by almost 40%, which allows to make a conclusion about the appropriateness of the selected method of exposure for the destruction of microorganisms E. coli and coliform bacteria. Processed, using high-frequency acoustic cavitation, cow's milk was used for the production of brine cheese-cheese. It is shown that cheese cheese had a high nutritional value, which is due to the preservation of essential substances in the raw material (in particular, calcium, which in the production of cheese cheese precipitates if pasteurized milk is used), elastic consistency, safety of consumer characteristics - microbiological and physico-chemical.

Low Fat Cheese

Cheese is not only created using cow's milk and can also be made from a mixture of vegetable extracts, including corn extract. Cheese from corn extract has the advantages of low-fat and high-carotene. Notably, papain can be used as a coagulant in the production of cheese analogue, while maltodextrin functions to increase volume and total solids for greater yield. The objectives of the present study was 1) to optimize the formula composition between lime extract, papain, and maltodextrin to create a cheese analogue from sweet corn extract with high yield and protein as well as good sensory properties, 2) to study the physicochemical and sensory characteristics of the cheese analogue using the optimal formula, and 3) to compare analog cheese from corn milk to cow's milk cheese. The experimental design involved response surface methodology with three factors (lime extract, papain, and maltodextrin). The results of the study produced the optimal cheese analogue formula from corn extract with the addition of lime extract (2.283%), papain (0.022%), and maltodextrin (15%). The characteristics of this cheese analogue include a yield of 20.3%; pH of 5.4; 14oBrix soluble solids; water content of 65.3%; protein content of 13.5%; total-carotene of 544.4 ppm and of fat content 4.6%. The cheese analogue has sensory characteristics of soft texture, the ability to spread evenly, the typical color of cheese (i.e. yellowish-white), and was preferred by panelists. Cheese analogue has protein content of 7.1%, fat content of 4.55%, total carotene of 544.4 mg/g, cholesterol 0.02 mg/g; while commercial cheese from cow’s milk has protein content 6.3%, fat content 24.53%, total carotene 5.32 mg/g and cholesterol 0.19 mg/g. Thus, sweet corn can potentially be used as a raw material for producing low-fat cheese analogues.

A total of 138 raw cow's and 57 raw ewe's milk samples; 80 pasteurized cow's milk samples; 39 Anthotyros cheese, 36 Manouri cheese, and 23 Feta cheese samples; and 15 rice pudding samples were examined for the presence and any countable population of Aeromonas species. Twenty-two (15.9%) of the 138 cow's milk samples analyzed were contaminated with A. hydrophila. In 13 of these samples, populations of 3.0 × 102 to 5.0 × 103 CFU/ml were counted in starch ampicillin agar (SAA). Eighteen cow's milk samples (13.0%) were contaminated with A. caviae, and in eight of these samples, populations of 2.0 × 102 to 3.0 × 103 CFU/ml were counted in SAA. Five cow's milk samples (3.6%) were contaminated with A. sobria, and in two of these samples, populations of 2.5 × 103 and 5.0 × 103 CFU/ml were counted in SAA. Eleven cow's milk samples (7.9%) were contaminated with other Aeromonas spp. not classified. Eight (14.0%) of the 57 ewe's milk samples analyzed were contaminated with A. hydrophila. In these samples, populations of 5.0 × 102 to 5.0 × 103 CFU/ml were counted in SAA. Six ewe's milk samples (10.5%) were contaminated with A. caviae, and populations of 1.5 × 102 to 1.0 × 103 CFU/ml were counted in SAA. Two ewe's milk samples (3.5%) were contaminated with A. sobria, and populations counted in SAA were 5.0 × 102 and 1.0 × 103 CFU/ml. Four samples (7.0%) were contaminated with other Aeromonas spp. not classified. A. hydrophila was recovered in 4 (10.2%) and 3 (8.3%) of the Anthotyros and Manouri cheese samples analyzed, respectively, but no countable populations were noted in SAA. None of the pasteurized milk, Feta cheese, and rice pudding samples yielded Aeromonas spp. The results of this work indicate that motile Aeromonas are common in raw milk in Greece. Also, the presence of A. hydrophila in the whey cheeses Anthotyros and Manouri indicates that postprocessing contaminations of these products with motile Aeromonas may occur during production.

Physical And Chemical

For the production of elite cheeses with mould, the basic raw material is cow’s milk, but goat’s milk is also of increasing interest. Goat milk has a high protein and fat content, is rich in vitamins, macro- and microelements. Therefore, the object of the study was represented by cow’s milk obtained from the Jersey cows and goat’s milk obtained from goats of the Saanen breed. According to physical and chemical parameters, the milk of cows and goats of these breeds was characterized by a high content of fat and protein, which affect the yield and quality of cheese. The goat milk cheese clot had a more delicate structure during the formation of the cheese layer and a sharp taste due to the different composition of medium-chain fatty acids. In the process of cheese ripening, changes in a number of physicochemical parameters such as cheese acidity, mass fraction of moisture, and amino acid composition of the protein are observed. On the 7–19th day of ripening, a cheese head gets covered with white mold, the cheese consistency becomes softer, and it starts smelling with a “mushroom” hue. Starting from the 15–22nd day, the cheese is completely covered with white mould and gets a smearing texture under the crust. Cheese made from goat’s milk have a more delicate consistency and structure of the cheese layer than those made from cow’s milk, which is most likely due to biochemical processes that occur when cheese is ripened.

In recent years, demand for products produced with goat milk has been increasing. On the other hand, compared to cow's milk, component and flavour differences in goat milk can cause significant differences in the properties of products produced with goat's milk and affect the acceptability of the product. In this study, it was aimed to compare the antioxidant capacity, rheological and sensory properties of kefir produced with goat milk with those properties of kefir produced of cow milk. In this context, cow milk, goat milk and 1: 1 ratio of cow and goat milk kefir were produced, physico-chemical, rheological and sensory analyses were performed. It was determined that the rheological properties of all kefir samples exhibit pseudoplastic behaviour and are compatible with the power-law model. The apparent viscosity of the kefir produced by the goat milk was lower than cow milk kefir. It was determined that the total antioxidant capacity of goat milk kefir was higher than cow's milk kefir and a and b values were lower in colour. On the other hand, in goat milk kefir, panellists perceived lower consistency and kefir flavour, also its overall acceptability score was lower. The addition of 50% cow's milk to goat's milk influenced the condition of goat's milk. The sensory properties of the mixture milk kefir were similar to the sensory properties of the cow's milk kefir. Although the mixture kefir positive results, it has been concluded that further studies are needed to obtain better consistency and flavour in kefir production from goat milk.
