Milk And Dairy Products

Milk and dairy products are important sources of nutrients in the human diet because they contain a number of essential substances and other biologically active components. Many of these substances can be modified, and thus offer opportunities to use milk and dairy products as functional food. Isoflavones are particularly important in human nutrition due to their diverse pharmacological and antioxidant properties. The clinical effectiveness of isoflavone-rich products is believed to be dependent on their ability to metabolize daidzein to equol, which may directly exert cancer preventive effects. However, only approximately 30–40% of humans are able to produce equol, while animals, in general, produce equol. Equol is the predominant product of bacterial metabolism of isoflavones and can be found in various amounts in some food of animal origin, especially in milk. Therefore, milk and dairy products can be considered to be sources of equol for humans who are not able to produce this metabolite. When the content of isoflavones in milk is to be modified, two groups of factors should be considered, i.e., dietary factors that include the source of isoflavones and the processing effects on feedstuffs and animal factors that include the intake of isoflavones, ruminal and postruminal changes, and the health and physiological status of animals. The approximate content of isoflavones in milk can be predicted using carry-over rates for different dietary sources or using a formula that describes the relationship between equol concentration in milk and formononetin intake. Processing and storage can affect the content and profile of isoflavones in milk and dairy products.

Diet in the first years of life is an important factor in growth and development. Dietary protein is a critical macronutrient that provides both essential and nonessential amino acids required for sustaining all body functions and procedures, providing the structural basis to maintain life and healthy development and growth in children. In this study, our aim was to describe the total protein intake, type and food sources of protein, the adequacy to the Population Reference Intake (PRI) for protein by the European Food Safety Authority (EFSA), and the Recommended Dietary Allowance (RDA) by the Institute of Medicine (IoM). Furthermore, we analyzed whether the consumption of dairy products (including regular milk, dairy products, or adapted milk formulas) is associated with nutrient adequacy and the contribution of protein to diet and whole dietary profile in the two cohorts of the EsNuPI (in English, Nutritional Study in the Spanish Pediatric Population) study; one cohort was representative of the Spanish population from one to < 10 years old (n = 707) (Spanish reference cohort, SRS) who reported consuming all kinds of milk and one was a cohort of the same age who reported consuming adapted milk over the last year (including follow-on formula, growing up milk, toddler’s milk, and enriched and fortified milks) (n = 741) (adapted milk consumers cohort, AMS). The children of both cohorts had a high contribution from protein to total energy intake (16.79% SRS and 15.63% AMS) and a high total protein intake (60.89 g/day SRS and 53.43 g/day AMS). We observed that protein intake in Spanish children aged one to < 10 years old was above the European and international recommendations, as well as the recommended percentages for energy intakes. The main protein sources were milk and dairy products (28% SRS and 29% AMS) and meat and meat products (27% SRS and 26% AMS), followed by cereals (16% SRS and 15% AMS), fish and shellfish (8% in both cohorts), eggs (5% SRS and 6% AMS), and legumes (4% in both cohorts). In our study population, protein intake was mainly from an animal origin (meat and meat products, milk and dairy products, fish and shellfish, and eggs) rather than from a plant origin (cereals and legumes). Future studies should investigate the long-term effect of dietary protein in early childhood on growth and body composition, and whether high protein intake affects health later in life.

Abstract Milk and dairy products contain a number of biologically active compounds (proteins, lipids, vitamins and minerals) that are essential for human nutrition. The most common procedures for demineralization are based on ion exchange-, nanofiltration- and electrodialysis-based technologies. In this study, the application of membrane filtration-based partial demineralization of cow milk was investigated and the process modelled. Using design equations, the partial demineralization process was designed and the economy of the process calculated. The modelling and simulation of the partial demineralization process was carried out by the SuperPro Designer programme. As the first step the unit operations of the demineralization technology were defined using the tools of the programme. The SuperPro Designer possesses industrial tools with reactor models, chemical components, a database of mixtures, and price estimations. By analysing the influence of the operation parameters, the feasibility of the proposed process was investigated. From the results of the modelling it can be concluded that the partial demineralization process can be successfully implemented, achieving the expected demineralization rates with a relatively good payback time of two years.

Cyclopropane fatty acids (CPFAs) are unusual fatty acids of microbial origin, recently detected in milk and dairy products. CPFAs have been demonstrated to be interesting molecular markers for authentication of dairy products obtained without ensiled feeds. Moreover, they can also be recognized as a new secondary component of human diet. Information is lacking on the presence of cyclic fatty acids in other food sources. Cyclopropane fatty acids have been detected by GC-MS analysis in cheese and other animal fats in concentration ranging from 200 to 1000 mg/kg fat, but in some cases, the complex fatty acid profile and the possible presence of interfering peaks make the separation not straightforward and the quantification uneasy. Therefore, a new reliable 1H NMR method was developed to detect and measure CPFA content in different foods of animal origin, based on the detection of the characteristic signals of cyclopropane ring. The 1H NMR (600 MHz) method showed detection limits comparable with those of full scan GC-MS, and it allowed the identification and quantitation of the cyclopropane fatty acids in different foods.

Low Cholesterol

Today's health conscious consumer is avoiding egg and dairy products. Traditionally, though, these foods were believed to be particularly wholesome and nutritious. Fifty years ago, Britain actively encouraged milk consumption, particularly by school children, with a National Milk Scheme (1940). At much the same time (1949), Romanoff and Romanoff's classic, ‘The Avian Egg’, enthusiastically supported eggs: ‘Compared with hens’ egg, no other single food of animal origin is eaten and relished by so many people the world over; none is served in such a variety of ways. Its popularity is justified not only because it is so easily procured and has so many uses in cookery, but also because it is almost unsurpassed in nutritive excellence’. But recently, cholesterol has emerged as a topic of polite conversation at dinner parties and most of us are aware, even if only vaguely and often inaccurately, of the connections between cholesterol and heart disease and eggs and dairy products. Fifty years ago the average Australian consumed 250 eggs per annum; today this consumption has declined to less than 135 eggs per annum (Castle, 1989). Similar declines in egg consumption have occurred in other developed countries over the same period of time. Hence there is interest worldwide in developing technologies to extract the cholesterol from foods, particularly eggs and dairy products, and a flurry of research activity has resulted.

Milk And Dairy Products

Milk and dairy products are an excellent environment for the development of microorganisms that can cause various defects in the products and in some cases lead to human disease. Under the action of bacteria, yeast, molds, if the rules of procurement are not observed, transportation, storage and sale of dairy products deteriorate rapidly, lose nutritional value, become dangerous for consumption. The purpose of the research was the monitoring of quality of dairy products sold in the trade network of Dnipro according to the sanitary-microbiological indicators. Material and methods. We analyzed 79 samples of milk and dairy products of different trade mark. 56 (64,5%) samples were not standard indexes from which 10 samples of pasteurized milk, 9 samples of yogurt, 6 samples of kefir, 8 samples of sweet-cream butter, 7 samples of cottage cheese, 6 samples of sour cream and 5 samples fermented baked milk. Results and discussion. The obtained results showed that 19 samples of dairy products contained less viable bacteria, than it was indicated according to sanitary and microbiological indexes. There was the greatest number of nonstandard products among samples of yogurt (6) and cottage cheese (4). The study showed that out of 56 analyzed dairy products 13 contained yeast in an amount that exceeds the standard rates. The largest number of non-standard samples (5) was found in yogurt. In 12 samples the maximum number of molds was exceeded. The highest number of molds contaminated product samples was found among cottage cheese (4), kefir (3) and butter (3). In the presence of sanitary-indicative microorganisms we did not meet the requirements of the normative indicators of 35 samples of dairy products, which was 44.3% of the total number of analyzed samples. Escherichia coli bacteria were found in samples of all types of dairy products. The most contaminated were samples of milk (6 samples), kefir (6 samples) and yogurt (5 samples). Conclusion. Out of 7 types studied most dairy products contaminated by all indicators were yoghurt and cottage cheese. Staphylicoccus aureus was detected in 2 samples of lactic acid products. Pathogenic bacteria, including representatives of the genus Salmonella and Listeria monocytogenes, were not found in none of 79 samples of seven types of dairy products

Diet has gained attention as a risk factor for the development of rheumatoid arthritis (RA), especially with regards to food of animal origin, such as meat and dairy products. By using data from national patient registers and dietary data from a large prospective population cohort, the Swedish Mammography Cohort, we aimed to investigate whether the consumption of meat and dairy products had any impact on the risk of subsequent development of RA. During 12 years of follow-up (January 2003–December 2014; 381, 456 person-years), 368 patients with a new diagnosis of RA were identified. No associations between the development of RA and the consumption of meat and meat products (hazard ratio [HR] for the fully adjusted model: 1.08 [95% CI: 0.77–1.53]) or the total consumption of milk and dairy products (HR for the fully adjusted model: 1.09 [95% CI: 0.76–1.55]) were observed. In conclusion, in this large prospective cohort of women, no associations were observed between dietary intake of meat and dairy products and the risk of RA development.

Anatoxins are produced by various types of Aspergillus spp. fungi in a wide variety of foods and feeds. Anatoxins are toxic to human and animals, acute and chronic. In humans, they can cause liver cancer, chronic hepatitis and cirrhosis. Among the four main aflatoxins (B1? B2, Gx and G2), aflatoxin Βχ (AFBi) is the most frequently found in feeds and the most toxic one. The most important aflatoxin in foods of animal origin is aflatoxin M4 (AFM4), which is the principal hydroxylated metabolite of AFB! AFM4 is mainly found in milk from lactating animals consuming feed contaminated with AFB^ Surveys carried on the occurrence of AFM4 in raw milk in various countries all over the world during the past 15 years, showed that contamination levels were low in European Union and USA, but high in certain countries of Africa, Asia and Latin America. Other global surveys on the occurrence of AFM4 in foods of animal origin (meat, eggs etch) showed that the level of the toxin is low as compared to milk and dairy products. European Union has set the maximum residual limit (MRL) for AFM4 of 0.05 μg/kg and 0.025 μg/kg in raw milk and milk powder for infants, respectively. In order to protect the consumer's health, control measures should be applied to avoid contamination of feed and foods with aflatoxins.

Aim. To determine the total polyphenols and antioxidant capacity and their correlation with antimicrobial and fungicidal properties in some species of the genus Allium growing in Tajikistan.Materials and methods. The objects of the study were 15 kinds of the Amaryllidaceae family. Antibacterial onions were studied by the disk diffusion method against 4 types of microorganisms (test strains) and 1 type of yeast fungus. In the presence of total polyphenols, the content in μg of Gallic acid (GA) per ml of plant extract was measured. To determine the antioxidant activity, a solution of ABTS K2S2O8 was used. Trolox was used as a standard.Results. The maximum content of total polyphenols is characterized by ethanol extracts of A. Carolinianum, A. altaicum, A. elatum, A. oschaninii, A. ramosum, A. hymenorhisum. At the same time, their lowest amount was found in the bulbs of A. longicuspis. A. shoenoprasum, which is statistically significantly lower than in all the above-listed species of this plant group. The extracts from the stems of A. carolinianum, A. elatum, and A. pamiricum had the highest antioxidant effect. There is a direct weak correlation between biologically active components with antimicrobial and fungicidal activity in A. oshaninii and A. suworowii, depending on the altitude gradient.Conclusions. The results allow suggesting that the above-ground and underground parts of some wild-growing endemic species of the genus Allium have different degrees of antioxidant activity due to total polyphenols. The content of total polyphenols and the antioxidant capacity of extracts obtained from various plants in different in large ranges. In some cases, there are direct correlations between the content of polyphenols, antioxidant properties, antimicrobial and fungal properties.

Staphylococcal food poisoning is considered one of the leading foodborne illnesses in humans worldwide and is associated with contaminated foods of animal origin, such as milk and dairy products. In this study, we investigated the occurrence of staphylococci and the enterotoxigenic properties of Staphylococcus aureus isolated from raw milk from yaks (Bos mutus) and cattle in Mongolia. Staphylococci were isolated from 72 (74%) of the 97 raw milk samples. Of the samples containing staphylococci, 69% (50 of 72) were from yaks and 30.5% (22 of 72) were from cattle. S. aureus was detected in 10% of yak (7 of 72) and 21% of cattle (15 of 72) milk samples. Staphylococcal enterotoxin C was detected in 23% (5 of 22) of the S. aureus strains investigated, based on the reverse passive latex agglutination technique. Three of the five enterotoxigenic strains were from yaks and two were from cattle. None of the S. aureus strains tested produced staphylococcal enterotoxins A, B, or D. To our knowledge, this is the first report of the occurrence of staphylococci and enterotoxigenic S. aureus in milk from yaks and cattle in Mongolia.

The stabilization of fruit bagasse by drying and milling technology is a valuable processing technology to improve its durability and preserve its valuable biologically active components. The objective of this study was to evaluate the effect of lyophilization and air temperature (60 °C and 70 °C) in hot air-drying as well as grinding conditions (coarse or fine granulometry) on physico-chemical properties; water interaction capacity; antioxidant properties; and carotenoid content of powdered lulo bagasse. Air-drying kinetics at 60 °C and 70 °C and sorption isotherms at 20 °C were also determined. Results showed that drying conditions influence antioxidant properties and carotenoid content while granulometry slightly influenced fiber and water interaction properties. Fiber content was near 50% and carotenoid content was higher than 60 µg/g dry matter in lyophilized powder. This β-carotene content is comparable to that provided by carrot juice. Air-drying at 60 °C only reduced carotenoids content by 10%.
