Mozzarella stretching water (MSW) is a dairy effluent generated from mozzarella cheese production that does not have a real use and is destined to disposal, causing environmental problems and representing a high disposal cost for dairy producers. Spent brewery yeast (SBY) is another promising food waste produced after brewery manufacturing that could be recycled in new biotechnological processes. Aurantiochytrium mangrovei is an aquatic protist known as producer of bioactive lipids such as omega 3 long chain polyunsaturated fatty acids (ω3 LC-PUFA), in particular docosahexaenoic acid (DHA). In this work MSW and SBY have been used to formulate new sustainable growth media for A. mangrovei cultivation and production of DHA in an attempt to valorize these effluents. MSW required an enzymatic hydrolysis to enhance the biomass production. The new media obtained from hydrolysed MSW was also optimized using response surface methodologies, obtaining 10.14 g L−1 of biomass in optimized medium, with a DHA content of 1.21 g L−1.

The article shows the prospects for the production of Mozzarella cheese of goat milk and dry sourdough. Cheese contains vital nutritional components, they are biologically complete and play an important role in the diet. Searching for new resources is an urgent problem. The solution may be to expand the range of cheeses not only of cow milk, but also of other farm animals, for example, goats. Their milk is absorbed faster and is used in medical and preventive nutrition. On the consumer market goat milk products are mainly represented by farms, and their range is small. The authors carried out the research on the selection of starter cultures containing probiotic cultures from bifidobacteria, acidophilus bacillus and thermophilic streptococcus, to optimize the technological process for the production of Mozzarella cheese based on goat milk. These cultures represent a beneficial microflora that inhabits the human body, helping to absorb nutrients and digest food. An important quality of probiotics that ensures their physiological effect is their high growth rate and compatibility with other microorganisms present in the gastrointestinal tract. It has been found that all the studied samples of goat milk in terms of composition have indicators that meet the requirements of GOST for goat milk. Comparative analysis of cow and goat milk has shown predominant indicators of the quality of goat milk in comparison with cow milk. The processes of coagulation and fermentation of goat milk under the influence of various starter cultures have been studied. The use of ABT-5-Probio-TecTM probiotic starter culture, which accelerates the technological process and imparts functional properties to the product, has been substantiated. The possibility of using goat milk in the production of cheeses with cheddaring and thermomechanical processing has been proven. Microscopic examination of a sample of Mozzarella cheese on ABT-5 sourdough has shown that bifidobacteria survive after heat treatment at high temperatures.

Buffalo Mozzarella cheese from Campania is one of the most worldwide appreciated Italian dairy products. The increased demand for buffalo dairy products and the limited availability of the finest buffalo milk has prompted the diffusion of illicit practices, such as the use of milk, curd, or other products that are frozen or bought at low cost. The aim of this research was to provide preliminary results about the trend of the microbial communities of buffalo milk, curd and Buffalo Mozzarella cheese, during freezing storage of eleven months. At the same time, the alterations of physical properties and the presence of the molecular marker “γ4-casein”, have been investigated. The results showed that freezing reduced the concentrations of the total bacterial count, Enterobacteriaceae, coliforms, Escherichia coli and yeasts in fresh milk and, the concentrations of the total bacterial count, coliforms, lactic acid bacteria and yeasts in mature curd. In the finished product, no notable decreases were observed, except for lactic acid bacteria. About the γ4-casein, no increase was observed in all matrices. These preliminary results allow us to conclude that the freezing process if properly carried out, does not compromise the microbiological quality and the physical properties of the Buffalo Mozzarella cheese.

During the manufacturing of mozzarella, cheese curds are heated to the desired stretching temperature traditionally by immersion in water, which influences the curd characteristics before stretching, and consequently the final cheese properties. In this study, cheese curds were immersed in hot water at 60, 70, 80 and 90 °C up to 16 min and the kinetics of mass loss and changes of rheological properties were investigated. The total mass of cooked curds increased up to 10% during the first minute, independent of the temperature, as a consequence of water retention. Fat was the main component lost into the cooking water (<3.5% w/w), while the concentration of protein increased up to 3.4% (w/w) compared to uncooked curds due to the loss of other components. Curds macrostructure during cooking showed that curds fully fuse at 70 °C/4 min; 80 °C/2 min and 90 °C/1 min, while after intensive cooking (>8 min) they lost the ability to fuse as a consequence of protein contraction and fat loss. Storage modulus, representing the curd strength, was dependent on cooking temperature and positively, and linearly, correlated with curd protein content (21.7–24.9%). This work shows the potential to modify curd composition and structure, which will have consequences for further processing and final product properties.
