The purpose of this study was to determine the further effect of soybean oil and phycocyanin extract against the quality of macronutrient (fat, protein, lactose) and also Solid Non-Fat (SNF) in cow’s milk. Two different substances, i.e., soybean oil and different amount of phycocyanin extract was added into the milk. The result showed the increase of protein content gradually from 3.49 ± 0.230 to 3.88 ± 0.010 when phycocyanin was added. The inverse with the decreased fat content from the control sample, but after the addition of phycocyanin extract, it was increased gradually 6.15 ± 0.210 to 6.35 ± 0.21. SNF has increased from 10.61 ± 0.014 to 10.87 ± 0.007, while the decreasing level of lactose has been shown from 5.74  ± 0.021 to 5.62  ± 0.028 due to addition of phycocyanin. In conclusion,  the addition of phycocyanin extract can increase the protein and SNF content of milk. This phycocyanin extract also acts as an antioxidant agent so that it can reduce the oxidation process, which might be caused by the addition of soybean oil. Soybean oil might be used as a food additive to improve the fat content of milk but must be accompanied by an antioxidant agent to prevent the oxidation process.

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.

Dairy Consumption

Cow's milk and dairy products derived from this complex food source have long been proposed as beneficial to human health, yet underlying clinical evidence of direct benefit continues to raise controversy. Limited evidence supports positive cardiometabolic effects of a number of dairy macro- and micronutrient components including whey protein and casein, unsaturated fats, milk fat globule membrane (MFGM) and polar phospholipids, vitamin D and calcium, in addition to non-bovine components including bacterial and yeast probiotics. More controversial remain lipid components trans fats, including trans vaccenic acid, trans palmitoleic acid, and conjugated cis trans linoleic acid (CLA), plus medium-chain and odd-chain dairy fats. New evidence is rapidly identifying multiple pathways by which these dairy nutrients may effect health. Processing, including fermentation and homogenization, may also have positive effects. Conversely, the high saturated fat content of dairy has long raised concern, aligned with international guidelines to minimize dietary intake of animal-origin saturated fatty acids (SFA) to achieve better cardiometabolic health. However, led in part by observational studies and meta-analyses showing dairy to have no or even an inverse association with cardiometabolic health, evidence from randomized controlled trials (RCTs) has been scrutinized over the last 5 years, and focus on low-fat dairy has been challenged. Recent evidence supports the hypothesis that adverse effects of SFAs on metabolic health may be ameliorated when these fats are consumed within a complex matrix such as milk, cheese or yogurt, and that dairy food categories may influence outcomes as much as total fat content. For example, yogurt and high-fat, high-SFA cheese have a negative association with risk of type 2 diabetes (T2D) in many, not all, published trials. However, large sample dairy RCTs of long duration with CVD or T2D incidence as primary endpoints are lacking. This is a clear research gap, with these clinical studies required if a causative link between dairy and improved cardiometabolic health is to be confirmed and in turn promoted through dietary guidelines. Current advisories from national guidance groups such as American Heart Association (AHA) and European Society of Cardiology (ESC) continue to promote consumption of low-fat dairy products, whilst liquid milk and yogurt remain part of nutrition guidelines from joint American Diabetes Association (ADA)/European Association for Study of Diabetes (EASD) reports, and as part of a “no-one-size-fits-all” answer to diet and T2D by the ADA in their most recent 2019 Consensus Report.

Selama berabad-abad susu telah dikenal sebagai bahan pangan yang dibutuhkan oleh manusia, karena susu banyak mengandung semua komponen bahan yang diperlukan oleh manusia. Kandungan terbesar susu adalah air dan lemak. Penelitian ini melakukan pengujian kandungan lemak pada susu sapi murni menggunakan gaya sentrifugasi, dengan tujuan untuk mengetahui pengaruh variabel berubah, berupa suhu yang digunakan dalam penimpanan susu yaitu 50C, 250C dan 300C, putaran yang digunakan selama percobaan yaitu 1772 rpm, 2080 rpm, 2455 rpm, 3266 rpm, dan 4080 rpm serta waktu yang digunakan yaitu 15 menit, 20 menit dan 25 menit terhadap pemisahan lemak dalam susu sapi murni. Uji analisa pada penelitian ini meliputi uji kandungan lemak, pH, densitas dan viskositas. Pada penelitian tersebut variabel paling optimal yaitu susu pada suhu 300C dengan kecepatan putaran 2455 rpm dan dalam waktu 25 menit mendapatkan hasil kandungan lemak sebesar 2,5ml. Sedangkan hasil pengukuran pH dari ketiga variabel mendapatkan hasil 6,5. Untuk densitas hasil yang didapat yaitu 1,014;1,052; 1,036 masing-masing pada suhu 50C,250C,300C dan untuk viskositas sebesar 1,46. Hasil penelitian menunjukkan bahwa tidak perbedaan signifikan pengaruh kecepatan putaran sentrifugasi terhadap densitas, pH maupun viskositas. Namun terdapat pengaruh putaran kecepatan sentrifugasi terhadap kadar lemak yang terpisahkan. Semakin tinggi suhu penyimpanan disertai peningkatan kecepatan putaran sentrifugasi, maka semakin tinggi kadar lemak yang terpisahkan.    Fat Content Separation Analysis from Dairy Milk by using Centrifuge For centuries dairy has been well known as the food needed by humans, due to its benefits for growth. The major content of milk is water and fat. This study examined the fat content of pure cow's milk using centrifugation force, with the aim to know the effect of independent variables, such as the temperature used in milk storage (5, 25 and 30 0C), the rotation speed of centrifugation (1772, 2080, 2455, 3266, and 4080 rpm) and the centrifugation time (15, 20 and 25 minutes) against the separation of fat in pure cow's milk. The analysis was including fat content test, pH, density and viscosity. In this study, the most optimum variables of fat content separation from milk (2.5 ml) were found at temperature of 300C with the centrifugation speed of 2455 rpm rotation and within 25 minutes. While, there were no different of the pH (6.5) and viscosity (1.46) regarding to the dependent variables. For the density, the results obtained are 1.014, 1.052; 1,036 for each at 50C, 250C, 300C. The result showed that there were no significant difference in the effect of centrifugation rotation speed to density, pH and viscosity. However, increasing the centrifugation rotation speed increased the fat content. The higher the storage temperature along with the increased speed of the centrifugation cycle, were resulted the higher the separated fat content.

1. Percentages of fat, solids not fat and protein were determined in over 700 samples of mixed milk from 15 herds during 1925–26. In the case of fat content, nine herds produced one or more samples below 3 per cent., one herd recording 25 per cent, of samples below this limit. With regard to solids not fat, twelve herds produced milk containing less than 8·5 per cent, on one or more occasions, the highest percentage of deficient samples recorded being 40.2. Frequency distributions of fat, solids not fat and protein percentages in the samples analysed, are given, together with standard deviations, and mean percentages with probable errors for these three constituents.3. Correlation tables of fat with solids not fat, and protein with solids not fat have been prepared, and graphs illustrating the variations are given.

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.
