The article highlights the current state of the production of dairy and vegetable food products. The results of studies of organoleptic and physical, chemical indicators of the quality of various herbal drinks: coconut, almond and oat, are presented, as well as an analysis and comparison with cow's milk, which is used in hotel and restaurant complexes in Bela Tserkva. For assessing the quality according to the organoleptic characteristics of the beverages, the following were examined: appearance, color, smell, taste and consistency. It was found that according to these indicators, herbal drinks comply with the regulatory documentation for these products. When assessing the quality by physical and chemical indicators, the mass fraction of fat, dry matter, titratable and active acidity, and density were established. The titratable acidity of milk-like drinks was within the normal range and did not exceed 10 ⁰T. The mass fraction of fat in coconut milk was 1.2 %, almond-rice milk – 1.3 % and oat milk – 2.4 %. Mass fraction of coconut milk solids was 7.6%, almond-rice 10.5% and oat milk 11.4%. The density of all types of herbal drinks was in the range of 1005–1015 kg/m3. The indicators of the quality of cow's milk, which is used in hotel and restaurant complexes, have been investigated in a comparative form. In terms of organoleptic indicators, the quality of cow's milk corresponds to the normative documentation. The fat mass fraction of cow's milk was 2.5 %, the mass fraction of solids was 12.5%, the titratable acidity was at the level of 18 ⁰T, the active acidity pH was 6.6, and the density was 1028 kg/m3. Analysis of various types of vegetable and cow's milk, which are used in hotel and restaurant complexes in the city of Bela Tserkva, in terms of physicochemical and organoleptic quality indicators, allows us to consider herbal drinks as substitutes for traditional products capable of providing the human body with essential nutritional factors.

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.

The objective of this study was to assess the effect of outside air temperature on the transportation temperature and processing quality of cow’s milk. The data used in the analyses (208 bulk samples) were collected on four farms over a period of 52 consecutive weeks. The samples were grouped into four outside air temperature‑based groups, namely: below 1.0 °C; from 1.1 to 8.0 °C; from 8.1 to 15.0 °C; above 15.1 °C. Mean values of the observed characteristics were as follows: average outside air temperature 7.40 °C, milk temperature on dairy farms 5.19 °C (at collection) and milk temperature on arrival at the dairy factory 5.60 °C. The average duration of transport was 211 minutes, milk volume in the tanker 12,885 l, fat content 4.13 %, protein content 3.40 %, lactose content 4.89 %, casein content 2.97 %, titratable acidity 6.31 SH, active acidity 6.75 (pH), rennet coagulation time (RCT) 201 sec., curd class 1.11 (on five‑point scale) and 1.49 (on ten‑point scale). Increasing outside air temperature was closely correlated (p < 0.01) with an increase in milk temperature at the dairy factory (at delivery). A significant (p < 0.01) increased difference between the temperatures on the farm (at collection) and at delivery in the dairy factory was also recorded. The titratable acidity decreased and so did the curd class on the ten‑point scale. Milk temperature on the farm (at point of entering transportation tank) also increased significantly (p < 0.01) with outside air temperature. Other differences were not significant (p > 0.05). Findings of this study suggest that outside air temperature influences the properties and processing quality of the transported milk, even though the temperature differences of the milk itself ranged within the acceptable limits. It therefore stands to reason that, when the temperature of milk on load is close to the recommended temperature limits it can exceed this limit during transportation to the dairy factory and cause significant damage to the processing quality of the transported milk.

AbstractUltrafiltration of skim cow’s milk with a UF10-PAN membrane at volume reduction ratios (VRRs) of 2 and 3 was performed. The ultrafiltration retentates obtained were used for production of probiotic yoghurts with three different starters. A control sample was prepared using skim cow’s milk. All yoghurts were analysed according to the following parameters: titratable acidity, dry matter, organoleptic characteristics, number of specific microorganisms (Lactobacillus bulgaricus and Streptococcus thermophilus) and the total count of viable lactic acid bacteria for 28 d of storage. The results showed that the increase in the VRR during ultrafiltration increased the titratable acidity, as well as the dry matter of all yoghurts. Ultrafiltration concentration led to an increase in the count of viable lactic acid bacteria in all yoghurts which improved their functional properties. The highest values of the total number of viable lactic acid bacteria were determined in yoghurts obtained with starter 1CM, followed by starters MZ2 and ZD for both VRRs. Probiotic yoghurts with the highest organoleptic evaluation were obtained from ultrafiltration retentates at VRR = 2 and starters 1CM and MZ2.

Проведена оценка питьевого молока, реализуемого в Самарской области, по сычужной пробе для выявления его пригодности к свертыванию. Исследована способность питьевого молока к образованию сгустка в зависимости от марки, способа упаковки, тепловой обработки и массовой доли жира. Проведен анализ 27 образцов пастеризованного и ультрапастеризованного молока по физико-химическим показателям и сычужной пробе по методикам ГОСТ. Установлено, что питьевое молоко с разной массовой долей жира (от 1,5 до 6,0%) способно к свертыванию, причем эта способность зависит от марки молока и способа его тепловой обработки (пастеризация или ультрапастеризация), но не зависит от способа упаковки и массовой доли жира в молоке. Только в 37% исследованных образцов молоко свернулось, ультрапастеризация оказала негативное влияние на способность к свертыванию. Сделан вывод о предпочтительном использовании молока марок Сарафаново, Пестравка, Ташлинское, Домик в деревне. Также необходимо учитывать нормативные значения рН, титруемую кислотность, плотность и органолептические характеристики молока. Установлено, что питьевое молоко может быть использовано как сырье для производства натурального сырного ароматизатора методом ферментной модификации, обладающего натуральным сырным ароматом без синтетических запахов и придающего вкус продуктам. Evaluation of drinking milk sold in the Samara region, by rennet sample to determine its suitability for coagulation was carried out. The ability of drinking milk to form a clot depending on the brand, method of packaging, heat treatment and fat mass fraction was investigated. The analysis of 27 samples of pasteurized and UHT milk according to physical and chemical parameters and rennet sample according to GOST methods. It is established that drinking milk with different mass fraction of fat (from 1,5 to 6,0%) is capable to coagulation, and this ability depends on brand of milk and a way of its heat treatment (pasteurization or ultra pasteurization), but does not depend on the method of packaging and the mass fraction of fat in milk. It is seen from 27 samples’ analysis, that only 37% of the milk was coagulated, and ultra pasteurization has a negative impact on the ability to coagulate. It is preferable to choose such brands as Sarafanovo, Pestravka, Tashlinskoe, Domik v derevne. It is also necessary to other points of consider are the normative values of pH, titratable acidity, density and organoleptic characteristics of milk. It was established that drinking milk can be used as a raw material for production of natural cheese flavoring by enzyme modification which has a natural cheese flavor without synthetic smells and makes products flavored.

The dairy industry seems to have convinced the food industry that whey is a miracle product. The list of supposed benefits it gives to food is as long as your arm. Some of the benefits may be real. Whey is the liquid remaining after milk has been curdled and strained. It is a by-product of the manufacture of cheese or casein and has several commercial uses. To produce cheese, rennet or an edible acid is added to heated milk. This makes the milk coagulate or curdle, separating the milk solids (curds) from the liquid whey. Sweet whey is the byproduct of rennet-coagulated cheese and acid whey (also called sour whey) is the byproduct of acid-coagulated cheese. Sweet whey has a pH greater than or equal to 5.6, acid whey has a pH less than or equal to 5.1. Whey is also a great way to add sweetness to a product without having to list sugar as an ingredient as whey contains up to 75% lactose. And it sounds healthy. This study is done to research the examinations for the production of mozzarella cheese from Cow’s milk, after research and analyses of a physical-chemical peculiar feature of whey from coagulum. We have followed the processes from the drying of whey from the coagulum analyzer's physical-chemical peculiar feature. We carried out three experiments. For every experiment, we took three patterns and analyzed the physical-chemical. The calculation was appraised statistically. This paper deals with the research of% of whey fat during the process of milk production from standardized to non-standardized milk. Where% of whey fat should be an economic indicator for standardizing milk for dairy production.

Objective: The aim of this work was to study the biochemical characteristics of coconut milk and its antigenic effect on the Balb/c mice immunized with α-lactalbumin protein, as well as its consequences on the structure of the intestinal epithelium.Methods: To achieve the objective of the study, an electrophoresis was realised on a polyacrylamide gel to determine various proteins contained in coconut milk. In addition, Lowry’s method was used to determine the amount of proteins in the formula. The antigenicity of coconut milk in sera was also studied using the Enzyme-Linked Immunosorbent Assay (ELISA) method. For the histological study, 21 w-old mice Balb/c were used and distributed in three groups of 7 mice each. Group 1, received a standard feed with no treatment (Negative control), group 2 and 3 received respectively a standard feed (Positive control) and coconut milk for a period of 28 d after being immunized with α- lactalbumin.Results: Analysis of the data revealed that the rate of proteins of cow’s milk is higher than that of the coconut milk ( p0.01). However, after carrying out the electrophoresis analysis, the coconut milk showed the absence of intact proteins. The anti α-Lactalbumin IgG titers significantly increased in positive control groups that received coconut milk (p<0.0001). Moreover, there was an increase of the intestinal villi height of mice fed with coconut milk, in the structure level of their intestinal epithelium compared to the negative control group.Conclusion: The findings of the study provide the evidence that coconut milk is a possible alternative to the cow’s milk formula in case of allergy.
