USING WHEY PROTEINS TO IMPROVE QUALITY OF YOGHURT MADE FROM COW'S MILK.

SummaryAfter an injection of oxytocin and the removal of residual milk, the milk obtained at the next milking had an increased content of sodium, chloride and whey proteins and a decreased content of lactose. The effect persisted for several milkings. It is suggested that this was due to a direct effect of oxytocin on the permeability of the mammary epithelium and that oxytocin should be used with caution in certain types of milk secretion experiment.

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.

Β Lactoglobulin

Protein analysis is very important both in terms of milk protein allergy, and of milk and dairy product adulteration (β-lactoglobulin may be an important marker in the detection of milk adulteration). The aim of this study was to detect major whey proteins α-lactalbumin and β-lactoglobulin and their genetic variants by reversed-phase high-performance liquid chromatography. Milk samples from cows (n = 40), goats (n = 40) and sheep (n = 40) were collected at two farms and milk bars in the Czech Republic from April to June 2010. The concentration of α-lactalbumin was higher in goat’s milk (1.27 ± 0.05 g·l-1, P < 0.001) and cow’s milk (1.16 ± 0.02 g·l-1, P = 0.0037) compared to sheep’s milk (0.95 ± 0.06 g·l-1); however, concentration of α-lactalbumin in goat’s milk and cow’s milk did not differ significantly (P < 0.05). Goat’s milk contained less β-lactoglobulin (3.07 ± 0.08 g·l-1) compared to cow’s milk (4.10 ± 0.04 g·l-1, P < 0.001) or sheep’s milk (5.97 ± 0.24 g·l-1, P < 0.001). A highly significant positive correlation (r = 0.8686; P < 0.001) was found between fraction A and B of β-lactoglobulin in sheep’s milk, whereas in cow’s milk there was a negative correlation (r = -0.3010; P = 0.0296). This study summarizes actual information of the whey protein content in different types of milk which may be relevant in assessing their allergenic potential.

Quality Of Milk

The article presents the results of experimental studies to determine the effect of antioxidant drugs “Butofan” and “E-selenium” on veterinary and sanitary parameters of cows’ milk obtained in the period after calving. Childbirth is characterized by a stressful physiological state of the body and a large amount of lipid peroxidation (LPO) products are formed in the blood of cows, which have a negative depleting effect on the body and, naturally, on the quality of milk, since it is a blood product. To enhance the work of the body’s own antioxidant system, since it is not always enough to neutralize LPO products, antioxidant drugs are used. It is necessary to determine veterinary and sanitary parameters in milk obtained under the influence of any drugs, since it is used in human nutrition. For this purpose, experimental studies were carried out on analogous dairy cows in one of the farms of Ryazan region. The cows were divided into three groups: the control and two experimental ones. The control group of animals was intact, the cows of the experimental groups received antioxidant preparations: the first one got “E-selenium” and the second one got “Butofan”. The research results showed that the milk yield of cows in the experimental groups was higher compared to the control. The quality parameters of milk in the experimental groups of cows were better in terms of fat content, protein content, density and acidity. Cow’s milk under the influence of antioxidant drugs was biologically complete and environmentally friendly.

Raw Cow’S Milk

Introduction. Currently, there are no bibliographic or statistical records that allow establishing a correlation between the physical-chemical quality characteristics of raw cow’s milk produced in the Republic of Panama and the classification it receives. Objective. To characterize and quantify the physical-chemical parameters of the quality of raw cow’s milk and correlate these characteristics with the classification that milk receives in Panama. Materials and methods. A stratified sampling was carried out according to the classification of raw cow´s milk (grade A, B, and C), 48 of grade A, 71 of grade B, and 393 of grade C. Random samples were taken in Cocle, Veraguas, Herrera and Los Santos during the rainy season from June to September 2018. In the Chiriquí province, the sampling was conducted during the dry season, from January to March 2019. In addition, it was necessary to have at least 512 producers or farms, so that the analysis reached a confidence level of 95 %, a standard deviation of 5 %, and a limit of error of 5 %. Results. The values found allow us to consider that the milk produced in Panama has the physical-chemical characteristics according to international standards. The correlation analysis indicated that the protein had a high relationship with solids non-fat (SNF), density (D), and lactose (L) (0.93, 0.91, and 0.96, respectively); also L is strongly related to SNF and D (0.94 and 0, 91, respectively). Conclusions. The analysis of variance did not allow to establish significant differences between the three existing classifications in the country, which allow a distribution of milk according to the grades of these parameters. However, it was possible to establish the existing correlation between some of these parameters.

Introduction: Regurgitation is a common issue in infants under six months of age who are at risk of esophagitis with excessive frequency and volume. This problem is due, in part, to allergies in the whey protein content in Cow's milk. Objective: The purpose of this research was to examine the connection between Cow's milk consumption and processed products by mothers with regurgitation frequency in infants. Method: This form of study is cross-sectional, with 44 respondents using a purposeful sampling technic in mothers who have children under six months of age. Analysis of data using the Independent t-test test with a nominal scale of data. Result: The findings showed an average regurgitation frequency was 2.4 times, and the results of the study showed an association between Cow's milk intake and refined goods by mothers with regurgitation in infants under six months with a p-value:0.014. Discussion: Enhanced frequency of regurgitation in mothers who consume Cow's milk and processed foods because of the risk of childhood allergy to the quality of Cow's milk protein, and it is advised that parents be conscious of the frequency of regurgitation due to mother-eaten food.
