The subject of research. The subject of the research is the production of soft cheese from goat's milk, the features of the technology used for the said, including milk-clotting enzymes and bacterial starter cultures. The purpose of research is to analyze the quality factors and the suitability of the starter culture for the production of soft cheese from goat’s milk to ensure a high yield of finished products, to study the effect of pasteurization modes on the curdling process. Materials and methods. When conducting research on the technological parameters of the production of soft cheese, various amounts of yeast, rennet, and calcium salt were added. The goat’s milk, starter culture, enzyme and calcium chloride available on the market were used. When determining the quality parameters of milk and finished products, we used standard methods for studying sensorial characteristics, determining the content of fat, moisture and dry matter, the mass fraction of protein, density and titratable acidity. Results of research. When conducting research, the duration of cheese mass formation was 8-14 hours. As the amount of added additional raw materials increased in each cheese sample, a decrease in the duration of the formation of the curd mass and the formation of a clot of different consistency were observed. The article also presents the results of studies of sensorial, physical and chemical parameters of samples of the finished soft cheese, describes the technological processes of the production of soft cheese from goat’s milk and the results of studies of factors affecting the quality of products. In particular, the technological parameters of obtaining soft cheese from goat’s milk, the procedure for pasteurization of the milk were studied, the optimal amounts of bacterial yeast, rennet and calcium chloride necessary for the production of cheese mass were determined, the effective concentration values of the enzyme and yeast that improve the physical colloidal properties of the protein clot were determined, these reducing the yield of dry matter during processing, increasing the output of finished cheese, the data on their impact on product quality is also provided. The benefits of the soft cheese made from goat's milk are due to the efficient use of raw materials, proper nutritional value and high yield of finished products. Sensorial, physical and chemical characteristics of ready soft cheeses have been studied. According to the results of the study, a sample of soft cheese from goat's milk was selected that fully meets the regulatory documents, without cheese defects in terms of physical and chemical parameters, fat content, moisture content, salt content, as well as sensorial properties. Scope of research results. The results of the research will be used to improve the technology for the production of milk products, namely, soft cheese from goat’s milk, to improve the food safety and consumer properties of the specified product.

     Fate of AflatoxinM1 in soft white cheese and its by-product (whey) and in yogurt locally made from raw sheep's and goat's milk experimentally inoculated with 0.05 and 0.5 µg/l AflatoxinM1 were investigated using ELISA technique. Results reported that AflatoxinM1 was concentrated in cheese at levels significantly higher than that recorded in the raw milk that used for its processing, with a significant decrease in AflatoxinM1 levels in its by-product (whey) comparable to the raw milk used in manufacturing at both inoculated levels. Yogurt produced from raw sheep's milk at second inoculated level exerted AflatoxinM1concentration significantly lower than that present in the milk. Significant differences in AflatoxinM1distribution in cheese and whey produced from sheep's milk comparable to their counterparts produced from goat's milk were recorded. Finally, results revealed the efficacious role of the various dairy manufacturing processes in AflatoxinM1 distribution and the necessity to issue of local legislations concerning the maximum permissible limits for AflatoxinM1 in milk in order to stay within the universal permissible levels for AflatoxinM1 in dairy products to provide greater protection for consumer health.

This study was aimed to determine the changes in kefir samples (CK and GK) made from cow’s and goat’s milk during frozen storage. The CK and GK samples were first stored at +4 °C for 14 and 21 days. Thereafter, all the samples were frozen at –35 °C for 24 h and kept at –18 °C for 45 days. There was no significant change in the fat, protein, acidity and pH values in both samples during the storage. The values of viscosity, WI and C* were higher in the CK samples while the syneresis value was higher in the GK samples throughout the frozen storage. The microorganisms ( Lactococcus spp., Lactobacillus spp., Leuconostoc spp., total mesophilic aerobic bacteria and yeasts) found in kefir made from goat's milk were more affected from the frozen storage. In both samples, the changes in organic acids and volatile flavor components were not significant during frozen storage, except acetic, citric and oxalic acids and acetaldehyde in GK sample. In addition, CK samples were preferred sensorially more by the panellists during frozen storage.

Two-dimensional electrophoretic (2DE)-based proteomics remains a powerful tool for allergenomic analysis of goat’s milk but requires effective extraction of proteins to accurately profile the overall causative allergens. However, there are several current issues with goat’s milk allergenomic analysis, and among these are the absence of established standardized extraction method for goat’s milk proteomes and the complexity of goat’s milk matrix that may hamper the efficacy of protein extraction. This study aimed to evaluate the efficacies of three different protein extraction methods, qualitatively and quantitatively, for the 2DE-proteomics, using milk from two commercial dairy goats in Malaysia, Saanen, and Jamnapari. Goat’s milk samples from both breeds were extracted by using three different methods: a milk dilution in urea/thiourea based buffer (Method A), a triphasic separation protocol in methanol/chloroform solution (Method B), and a dilution in sulfite-based buffer (Method C). The efficacies of the extraction methods were assessed further by performing the protein concentration assay and 1D and 2D SDS-PAGE profiling, as well as identifying proteins by MALDI-TOF/TOF MS/MS. The results showed that method A recovered the highest amount of proteins (72.68% for Saanen and 71.25% for Jamnapari) and produced the highest number of protein spots (199 ± 16.1 and 267 ± 10.6 total spots for Saanen and Jamnapari, respectively) with superior gel resolution and minimal streaking. Six milk protein spots from both breeds were identified based on the positive peptide mass fingerprinting matches with ruminant milk proteins from public databases, using the Mascot software. These results attest to the fitness of the optimized protein extraction protocol, method A, for 2DE proteomic and future allergenomic analysis of the goat’s milk.
