In this process of extracting Milk Plastic Water Resistant Glue from the casein 3 type of milk soya milk, fresh cow milk and the pastured milk were used. Casein was extracted and vinegar was added while milk was getting heated. Casein was separated, and dried for 2-3 days. Milk Plastic that was obtained was heated with distilled water. A pinch of papain is added and made it hot for 4 hours and then 1N of NaOH is added and heated for few minutes. The collected sample is centrifuged at 12000 rpm and the glue was obtained. The glue is stored at -200C. 2 card board pieces was stacked together by using this glue and dipped in water to check the water resistance. It was stable for about 10 minutes and then it was loosened. It is little expensive comparing to other glues when it was did with pure milk while if it is done with waste milk product its cost will be low.

Adulteration of goat milk is usually done using cow’s milk product. Cow milk is used as it is widely available and its price is cheaper compared to goat milk. This paper shows a development of candidate tools for milk adulteration using cow milk. A quartz crystal microbalance immunosensor was developed using commercial crystal resonator and polyclonal antibody specific to cow milk protein. A specific protein at 208 KDa is found only in cow milk and does not exist in goat milk. The existence of this protein can be used as an indicator of cow milk content in a target solution. To detect the PSS 208 kDa protein, antibody specific to the PSS 208 was developed. The purified antibody was immobilized on top of the sensor surface on a polystyrene layer. The fraction of the immobilized antibody on the sensor was found at 1.5% of the given antibody. Using a static reaction cell, the developed immunosensor could detect the specific cow milk protein in buffer solution. The detection limit is 1 ppm. A linear relationship between frequency change and specific protein of cow milk concentration is found from a concentration of 1 ppm to 120 ppm.

A biodegradable urea crosslinked starch film was prepared. To improve the water resistance, the urea crosslinked starch system was reinforced with 5%, 10%, and 15% lignin. The prepared films were immersed in distilled water at three different temperatures, 25°C, 35°C and 45°C to study the behavior of water uptake. The addition of lignin effectively decreases water uptake as proven by lower water uptake equilibrium. Diffusion coefficient was calculated from the kinetic water uptake profile using the slope method of Fick’s second law for thin slab model. The calculated diffusion coefficient decreases as the lignin is increased. The diffusion coefficient is found to be dependent on the temperature. As more lignin is added to the system, higher activation energy is obtained due to the hydrophobicity of lignin.

Stereospecific analysis is an important tool for the characterization of lipid fraction of food matrices, and also of milk samples. The results of a chemical-enzymatic-chromatographic analytical method were elaborated by chemometric procedures such as linear discriminant analysis (LDA) and artificial neural network (ANN). According to the total composition and intrapositional fatty acid distribution in the triacylglycerol (TAG) backbone, the obtained results were able to characterize pure milk samples and milk mixtures with 1, 3, 5% cow milk added to donkey milk. The resulting score was very satisfactory. Totally correct classified samples were obtained when the TAG stereospecific results of all the considered milk mixtures (donkey-cow) were elaborated by LDA and ANN chemometric procedures.

Product authenticity is an important topic in dairy sector. Dairy products sold for public consumption must be accurately labelled in accordance with the contained milk species. Linear discriminant analysis (LDA), a common chemometric procedure, has been applied to fatty acid% composition to classify pure milk samples (cow, ewe, buffalo, donkey, goat). All original grouped cases were correctly classified, while 90% of cross-validated grouped cases were correctly classified. Another objective of this research was the characterisation of cow-ewe milk mixtures in order to reveal a common fraud in dairy field, that is the addition of cow to ewe milk. Stereospecific analysis of triacylglycerols (TAG), a method based on chemical–enzymatic procedures coupled with chromatographic techniques, has been carried out to detect fraudulent milk additions, in particular 1, 3, 5% cow milk added to ewe milk. When only TAG composition data were used for the elaboration, 75% of original grouped cases were correctly classified, while totally correct classified samples were obtained when both total and intrapositional TAG data were used. Also the results of cross validation were better when TAG stereospecific analysis data were considered as LDA variables. In particular, 100% of cross-validated grouped cases were obtained when 5% cow milk mixtures were considered.

Although causality is yet to be confirmed, a considerable volume of research has explored the relationships between cow milk consumption, type II diabetes, and cardiovascular disease. Contrastingly, it has not been comprehensively examined whether milk of non-bovine origin can provide cardiometabolic protection. This narrative review outlines the marked differences in macronutrient composition, particularly protein and lipid content, and discusses how whole milk product (and individual milk ingredients) from different species could impact cardiometabolic health. There is some data, although primarily from compositional analyses, animal studies, and acute clinical trials, that non-bovine milk (notably sheep and goat milk) could be a viable substitute to cow milk for the maintenance, or enhancement, of cardiometabolic health. With a high content of medium-chain triglycerides, conjugated linoleic acid, leucine, and essential minerals, sheep milk could assist in the prevention of metabolic-related disorders. Similarly, albeit with a lower content of such functional compounds relative to sheep milk, goat and buffalo milk could be plausible counterparts to cow milk. However, the evidence required to generate nutritional recommendations for ‘non-bovine milk’ is currently lacking. Longer-term randomised controlled trials must assess how the bioactive ingredients of different species’ milks collectively influence biomarkers of, and subsequently incidence of, cardiometabolic health.

UTILIZATION OF SEVERAL SUCROSE LEVELS ON SENSORY CHARACTERISTICS OF COWS MILK. The present study was conducted to investigate the utilization of several sucrose levels on sensory characteristics of cow milk kefir. Materials used in the study were: UHT milk, grain kefir, skim milk, sucrose, distilled water (aquadest), alcohol, spiritus or methylated spirit.  A Completely Randomized Design (CRD) with 5 treatments and 40 replications (panelists) was used in the present study. Treatments were formulated as follow: A0= sucrose 0% + grain kefir 5%, A1= sucrose 2% + grain kefir 5%, A2= sucrose 4% + grain kefir 5%, A3= sucrose 6% + grain kefir 5%, and A4= sucrose 8% + grain kefir 5%. Sensory test was conducted using hedonic scales. Variables measured were: sensory characteristics consisted of colors, aroma, viscosity, and taste. Tukey test was further employed to analyze treatment differences. Different between treatment(s) was declared at P < 0.05.  Research results showed that sucrose levels at 0%, 2%, 4%, 6%, 8% treatments gave a significant effect (P < 0.01) on aroma, viscosity, and taste, but color was not affected (P > 0.05) by treatments. It can be concluded that the utilization of sucrose at the level of 6% (A3) as most preferred by panelists based on sensory characteristics colors, aroma, viscosity, and taste. Keywords : Kefir, Grain Kefir, Sucrose, Sensory

In the Lithuanian metal working plants galvanotechnical slime is formed during the manufacturing process. It consists of Fe, Ca, Mg and combinations of microelements Cr, Mn, Co, Ni, Cu, Zn, Cd, Pb such as hydroxide, sulphide etc. To prevent contamination of the environment by metal combinations contained in the galvanotechnical slime it has to be utilized for ceramic products during the manufacturing process. In Lithuania the galvanotechnical slime is utilized for ceramzite produced in the Palemonas factory. The aim of this work is to find out whether the microelements contained in galvanotechnical slime are emitted from ceramzite into the environment while ceramzite is affected by water. There is hydromical clay in Lithuania. Cremate clay contains 70—95% of hydromicas, 5—30% kaolinite, and up to 5% of chlorite and traces of montmorillonite. It contains quartz, feldspars, calcite and limonite as well. Oxidical structure (%) is: SiO2 48–51, Al2O3 + TiO2 14—19, Fe2O3 5—8, CaO 7–11, MgO ∼ 3, K2O ∼ 3, Na2O ∼ 1, SO3 up to 0.4, loss by roasting 10—13. In producing ceramzite (1050—125°C) mullite, quartz, hematite, magnetite, anorthite, spinel, forsterite etc. are formed from clay components. If ceramzite contains galvanotechnical slime, the microelements along with ceramzite components compounds thermodynamically a few of Ca, Mg, Fe, Ni, Cu, Zn silicates and aluminates and Ca, Mg, Ni, Cu ferrites. The amount of microelements transferring from ceramzite into water has been defined with the atomicabsorption spectroscopy by keeping ceramzite granules in distilled water for 3,6 and 12 months. The results of the investigation demonstrate that the compounds of Cr, Ni, Cd, Pb, Mn, and Co do not transfer from ceramzite into water. The amounts of metallic compounds in the water C H 2 O are limited by the values of their solubility product L: C H 2 O = 5,62 Cmax L0,087, The amount of metallic compounds in the water C H 2 O depends on the extraction length according to the satiation curve. The results of the investigation show that ceramzite containing galvanotechnical slime is an ecologically clean heat insulating substance.
