The aim of the study was to assess the antioxidant potential of goat’s milk and whey from goat’s milk fermented with selected bacteria strains from kefir grain (L. plantarum, L. fermentum, L. rhamnosus and L. acidophilus) with regard to fermented cow’s milk with the same bacteria strains. The assessment of antioxidant potential was made by ABTS, DPPH, TPC and FRAP methods. The work also assessed metabolic activity of tested lactic acid bacteria using measurement of electrical impedance changes in the growing medium. The highest values describing the antioxidant potential were found for fermented milk by L. acidophilus. It was also found that the time of cooling storage causes significantly increasing the antioxidant potential of most analyzed samples. Metabolic activity of tested lactic acid bacteria was the highest for cow’s milk. The course of curves for goat’s milk and whey from goat’s milk was similar, which confirms the differences between cow and goat milk.

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.

Yoghurt is a well-known fermented dairy product which produced using a combination of lactic acid bacteria (LAB) of Streptococcus thermophilus, Lactobacillus bulgaricus and L. acidophillus as fermentation starters. Cow milk is usually used as a raw ingredient. The LAB-based local yoghurt starter (S. thermophilus RRAM-01 (ST), L. bulgaricus RRAM-01 (LB) and L. acidophilus IIA-2B4 (LA)) were previously isolated from milk and meat, nevertheless had not been extensively attempted to be used in yoghurt production. This study aimed to evaluate the characteristics of cow and goat milk based yoghurt produced by using a single local strater of S. thermophilus RRAM-01 (ST) or L. bulgaricus RRAM-01 (LB) or L. acidophilus IIA-2B4 (LA). The yoghurts were produced through addition of the starter (3% v/v each) with 1010 CFU mL-1 of initial population, and then fermented at room temperature for 24 hr.  The result revealed that initial population of LAB in goat’s milk yoghurt fermented by ST or LB were significantly higher than that of by LA. Yet, after 24-hour of storage at room temperature, the total population of LA increased and reached final population which was higher than LB or ST. Meanwhile, cow’s milk yoghurt fermented by LB had the highest population of at the initial day (D0), while after fermentation the highest population were observed on LB or LA cow’s milk yoghurt. Overall goat’s milk yoghurt had significantly lower pH values than the cow’s milk yoghurt. These were accompanied by higher the total titrated acid (TTA) of goat’s milk yoghurt than that of cow’s milk yoghurt. Based on pH and TAT values, it was found that  ST bacteria produced significantly higher total acidity goat’s milk yoghurt, followed by LB and LA. However, the type of culture had no effect on total acidity of cow's milk yoghurt.

This research was conducted to study the key physicochemical parameters of samples of raw bovine and goat milk collected in the steppic region of Djelfa. One hundred and six samples of raw milk were collected from April 2018 to May 2018, at points of sale and analyzed. The results showed that cow’s milk had 3.66±0.89% fat, 11.4±1.56% solid not fat, 4.35±0.61% protein, 6.35±0.89% lactose and a density of 1.0360±0.0056 with a freezing point of -0.380±0.053 °C. While goat’s milk had 3.43±0.65% fat, 10.2±0.92% solid not fat, 3.88±0.36% protein, 5.66±0.52% lactose and a density of 1.0317±0.0035 with a freezing point of -0.348±0.044 °C. This proves that cow’s milk has a slightly higher physicochemical quality than goat’s milk. In addition, the present study showed that 100% raw goat milk is wet against 97.1% raw bovine milk. This indicates the presence of cases of fraud requiring disciplinary procedures. Moreover, in the majority of the cases, the storage temperatures of the milk far exceed the values recommended by the Algerian standards (+6°C). It is necessary to establish a program of control and popularization of all the actors of the sector in order to improve the quality and the quantity of raw milk produced.

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.

Mother’s milk is the most suitable product for feeding a newborn baby, its uniqueness is obvious. However, there are situations when breastfeeding is not possible at all or its volume is limited, so under certain circumstances mothers are forced to partially supplement or completely feed the child with an artificial formula. Although the composition of the ingredients in most modern formula feeds is similar, there are nevertheless differences in their composition and in the processing of the ingredients in the formula. In addition, the child may have individual taste preferences as well as unexpected negative reactions to any adapted milk formula. This review presents the achievements of recent years in creating adapted goat’s milk-based formulas for feeding newborns and first-year infants. Goat’s milk-based formulas have a number of advantages over cow’s milk-based formulas. One of the representatives of modern artificial formulas are those containing goat’s milk, which is characterized by low α-s1-casein genotype and high β-lactoglobulin content, which provides easier protein digestibility, contributes to more comfortable digestion and better absorption. Knowledge of the biological and nutritional value of goat milk, taking into account the peculiarities of the gastrointestinal tract of newborns and their needs, made it possible to develop and introduce into the goat’s milk-based formula the DigestX lipid complex, which is a complex of vegetable oils with a high content of palmitic acid in the sn-2-position in the triglyceride molecule, which is similar to breast milk. Goat’s milk, compared to cow’s milk, contains 4-6 times more oligosaccharides, which retain their beneficial properties in the production of artificial goat’s milk formula.Recent scientific literature data is presented, including that from the standpoint of evidence-based medicine, proving the effectiveness and safety of artificial goat’s milk-based formulas. The necessity of consulting mothers, psychological support and practical assistance not only in breastfeeding, but also in artificial feeding is substantiated.

Probiotic Effect

For milk and dairy products, 70 % of the Kazakh market accounts for the products of foreign companies. Geographically, the problem of the production of domestic products, the ecology of which is characteristic of the population of the country, has not yet been solved. The existing starter cultures are currently mainly intended for cow's milk, and are not adapted to the milk of other animal species. However, the production and processing of camel, mare and goat milk is a dairy farm with a history and traditions in the Republic of Kazakhstan. The fermentation process with the help of lactic acid bacteria is the basis for the preparation of products such as kefir, koumiss and shubat. There are data on the use of lactic acid bacteria in starters, but there is little data in studies on their use as starter cultures for camel, mare and goat milk, there are no scientific experimental results. Despite the economic rates of production of fermented products based on camel, mare and goat milk in the Republic of Kazakhstan, their production is slowed down at the industrial level due to the lack of yeast cultures and dairy technology for these types of milk. In this scientific work, fermenting consortia based on goat's milk was developed from active strains of microorganisms isolated from traditional fermented milk products, taking into account their compatibility, biochemical characteristics and scientific foundations. The technological, nutritional and microbiotic properties of the finished starters were adapted to the probiotic effect of camel, mare and goat milk by changing their composition. As a result of the study, a consortium of starters with a very high probiotic effect, safe for life, prone to survival in the digestive system was proposed.

Whey kefir is an isotonic drink with good quality, because it is most suitable for human and animal body fluids. Scientific information relating to the use of whey through the fermentation process using a kefir starter to see the functional benefits of antihypertensive has not been widely published, therefore this research is important to do. So that they can know and learn the quality of kefir whey against antioxidant and mineral content. This study aims to determine the volume of kefir whey from goat's milk and cow's milk produced by giving different levels of kefir starter. The method used is an experimental study that uses two factors, namely comparing whey kefir goat milk with cow milk whey. The experimental design used was a randomized block design (RBD) with 3 treatments performed 3 replications. The experimental design in this study was a 3x2 factorial design of the independent variable that is, whey kefir using goat's milk and cow's milk was repeated 3 times. 3% KSKO kefir starter (control), 5% KSK kefir starter, 10% KSK2 kefir starter, 15% KSK3 kefir starter. The dependent variable in this study is the laboratory test of antioxidant content, pH, acidity, total lactic acid bacteria. So that this study can be concluded that the volume of kefir whey produced at the addition of different levels of kefir grain to the whey volume of goat milk and cow milk produced is significantly different.

Dadih is a dairy-based product and it is one of the most popular desserts among Malaysians and Indonesians. It is made from raw milk which naturally contains various types of microorganisms. This study was conducted to develop cultured dadih by inoculating various Lactobacillus species such as Lactobacillus acidophilus, Lactobacillus plantarum and Lactobacillus paracasei into dadih made from cow’s milk and goat’s milk. Prior to isolation of LAB from control dadih (dadih without inoculation with LAB), the dadih was stored at 4˚C for 48 hours. The microbiological (general microbial load, viability of and LAB, mould and yeast count) and physicochemical properties (pH, lactic acid content, total soluble solid, colour, texture and proximate composition) of dadih with different LAB strains and without LAB strain were determined. Results showed that L. paracasei spp. paracasei, Lactobacillus brevis, Lactobacillus casei were isolated from cow’s milk dadih while only L. paracasei spp. paracasei was isolated from goat’s milk dadih. The number of LAB ranged from 5.73 to 6.06 log10 CFU/g for cow’s milk dadih and 5.19 to 5.88 log10 CFU/g for goat’s milk dadih. Results revealed that dadih inoculated with LAB has lower pH and greater amount of lactic acid produced than control dadih. Total soluble solid for dadih with LAB also decreased. Hardness of dadih without LAB culture was higher compared to the inoculated dadih with LAB cultures. Proximate compositions (moisture, ash, crude fat, crude protein and total carbohydrate) showed variations due to differential formulations and incorporations of different LAB strains. Findings showed that L. acidophilus was chosen as the best starter culture for both types of dadih because it has significant effects on pH, titratable acidity, total soluble solid and texture of the dadih.

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.

Introduction. The main principle of treatment of cow’s milk allergy (CMA) is the elimination from the diet of cow’s milk. However recently has been discussing the possibility to substitute the cow’s milk with goat’s milk in children with allergy to cow s milk protein. Background. To determine the relationship between sensitization to cow’s milk specific allergens in goat’s milk sensitized children. Methods. The study included 88 children with suspected allergy to CMA. All patients underwent determination of specific IgE to allergen of cow’s and goat’s milk allergen (ImmunoCAP 100 Phadia AB). We identified 35 children with sensitization to cow’s milk and measured specific IgE to α-laktalbumin, β-lactoglobulin and casein. Results. Sensitization to goat’s milk was estimated in 83% of patients with sensitization to cow’s milk. There was a significant positive correlation between the concentration of specific IgE to goat’s milk allergen and specific IgE to the cow’s milk allergen (R=0,91, p=0,0000001), a-laktalbumin (R=0,76, p=0,000007), β-lactoglobulin (R=0,72, p=0,000038) and casein (R=0,91, p=0,0000001). Conclusion. Formulas based on goat milk can not be considered hypoallergenic for children allergic to cow’s milk. Crosssensitization is mediated mainly with sensitization to casein. Introduction of goat milk and its derivatives in the diet of a child with an allergy to cow’s milk can be proven only by the absence of clinically relevant sensitization to goat milk.
