Mozzarella Cheese

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.

The main objective of this paper is to evaluate the influence of starter culture (fast and slow) on the technological process and the quality of dried salami. For each finished product were made the same analyzes: the fat content, protein, sodium chloride content, nitrite and moisture content. Following the experimental research, it was found that for slow culture, higher values were obtained in the case of protein content (15.2%) and salt content (2.98%). In the case of fast culture, higher values were obtained for the following properties: moisture (38.32%), fat (29.57%) and nitrites (5.42 ppm). The evolution of the pH every 24 hours in the first 7 days was also monitored, and it can be notice that after 6 days the pH reached the same value for both cultures (6.9) although initially in the case of slow starter cultures the pH was slightly higher.

Ph Values

The production of fermented milk using cow milk, goat milk and a mixture of them (1:1) was evaluated. The traditional yogurt starter culture was used—Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus, along with Lactobacillus casei ATCC 393. The objective was to monitor the viability of these cultures during the storage of fermented milk at 4 °C for up to 28 days. Storage significantly affected the viability of all microorganisms and especially L. bulgaricus. All microorganisms retained viable numbers higher than 7.5 log CFU g−1, even after 4 weeks of storage, which is important to confirm the probiotic character of the product. The use of goat milk significantly affected the pH and acidity of fermented milk. More specifically, the use of goat milk led to fermented milk with lower pH values and higher acidities than fermented milk with cow milk. The sensory evaluation ascertained the overall quality of fermented milk with a mixture of cow and goat milk, which scored similar values to the commercial sample.

The Impact

Abstract Italian salami is a cured meat with high sodium contents which is easy, fast and convenient to consume. Starter cultures are used to improve its sensory characteristics and refine its technological manufacturing process. The goal of this study was to reduce the sodium content in Italian salami through the partial replacement of sodium chloride by potassium chloride, magnesium chloride and calcium chloride, and evaluate the viability of the Lactobacillus sp. and Staphylococcus sp. cells found in the starter culture. Four formulations were elaborated: one with, and one without the starter culture, but both with the addition of sodium chloride; and two with the partial replacement of 60% of the sodium chloride: the first with KCl, and the other with a mixture of KCl, MgCl2 and CaCl2. Physicochemical and microbiological evaluations were carried out to monitor the ripening and the quality of the final product. The partial replacement of NaCl by other salts (MgCl2, CaCl2, KCl) did not interfere in the growth of the starter culture in the Italian salami, neither did it affect the majority of the physicochemical parameters of the Italian salami nor the microbiological quality of the final product.

Background: The present study was undertaken to study the effect of different packaging methods on the shelf-life of iron fortified mozzarella cheese prepared from cow milk, goat milk and mixed milk using kiwi fruit extract.Methods: Mozzarella cheese samples were packed both aerobically and under vacuum packaging condition and microbiological load (Total viable count, Escherichia coli, Salmonella, Shigella, Staphylococcus aureus, yeast and moulds and spores count) were monitored throughout the storage period in order to determine its shelf-life. Result: The total viable count (TVC) increased gradually from 0 day till 15 days of refrigerated storage for all the samples of iron fortified mozzarella cheese under both aerobic and vacuum packaging conditions irrespective of the types of milk and enzymes used. Under aerobic packaging condition, highest total viable count was observed for goat’s milk sample in both control and treatment groups all throughout the storage period. Mixed milk iron fortified mozzarella cheese exhibited least count in both the groups. The TVC of all the cheese samples were higher in aerobic packaging compared to vacuum packaging condition. The shelf-life or best before use of the product could judged as 15d from the date of manufacturing.

Organoleptic Evaluation

The purpose of this study was to determine the profile of volatile compounds (aroma) and overall flavor in dessert yogurts prepared from cow and goat milk, using three different, commercially available starter cultures, in the presence or absence of probiotic bacteria and to correlate this to organoleptic evaluation results obtained using a consumer acceptability method. The extraction of volatile compounds was carried out by solid phase micro-extraction; separation and analysis by gas chromatography-mass spectrometry. Variations among the different classes of compounds (i.e., aldehydes, alcohols, ketones, volatile acids, hydrocarbons, and terpenes) were recorded for different treatments. The results showed that the main volatiles in the cow milk dessert yogurts without Bifidobacterium BB-12 were: acetaldehyde, 2,3-butanedione, 2,3-pentanedione, 3-OH-2-butanone, 2-propanone, hexanoic acid and limonene). Respective volatiles in cow milk dessert yogurts with Bifidobacterium BB-12 were: acetaldehyde, pentanal, hexanal, the same ketones, acetic acid and limonene). The volatiles in goat milk dessert yogurts without Lactobacillus acidophilus LA-5 were: acetaldehyde, the same ketones, no carboxylic acids, limonene, camphene, α- and β-pinene. Respective volatiles in goat milk dessert yogurts with Lactobacillus acidophilus LA-5 were: aldehydes acetaldehyde, the same ketones, butanoic acid, α-pinene and camphene varying in concentration in different samples. Based on the results of volatiles and organoleptic evaluation, it can be concluded that dessert yogurts from cow milk without probiotic bacterial strains using the mild and classic starter cultures, and dessert yogurts from goat milk with probiotic bacterial strains using the classic and acidic starter cultures are found to be more organoleptically acceptable by consumers. In most cases, a positive correlation was found between dessert yogurt organoleptically determined flavor and volatiles (aldehydes, ketones and carboxylic acids).

One of the promising technologies for cheese making is cheddaring of cheese mass; it is desirable that the cheddaring takes place as soon as possible. The article considers the possibility of using acidophilus bacillus to intensify the cheddaring process. As starter cultures, the bacterial concentrate AiBi LcLS 30.11 and sourdough of acidophilus bacillus with inviscid BK-Uglich-ANV in a ratio of 5:1 were used. The cheddarization of cheese mass using a starter culture with acidophilus bacillus took 3 hours, while the cheddarization time was reduced by 2–4 hours. The optimum acidity of the serum is 65–70 ° T (pH 5.45–5.50), the thermomechanical processing requires water. Cheese produced using acidophilus bacterium meets the organoleptic and physico-chemical parameters.

The technology of rye-wheat bread from frozen semi-finished products of high readiness for preventive purposes using grain starter culture has been developed. To prepare the starter culture, wheat grain was sprouted for 12–13 hours at a temperature of 23–25°C; then water was added to the crushed grain mass in a ratio of 1 : 1 and solutions of xylanase-acting enzyme preparations. The resulting mixture was kept for 2 hours at a temperature of 40°C. The dough was prepared using a thick rye sourdough, as well as grain starter cultures at a ratio of 60 : 40 rye skinned and wheat flour of the first grade, respectively. Baked semi-finished products were cooled in natural conditions, Packed and placed in a freezer at a temperature of –27°C. After defrosting, the product was baked to 100% readiness. Analysis of physical and chemical quality indicators of rye-wheat bread made from frozen semi-finished products showed that the use of grain starter cultures improves the quality of finished bread and preserves its main indicators after cryopreservation. Specific volume of bread samples on sourdough thick rye/grain, cm3/g: 2,2/2,4; humidity, %: 44,5/44,0; degree of acidity 4,4/3,8; porosity, %: 64/60; total deformation, mm: 3,0/3,3 respectively.

Abstract This study aimed to compare the effect of different ratios of Streptococcus thermophilus to Lactobacillus bulgaricus (3 : 1, 1 : 1, and 1 : 3) under the various stressful temperatures (37 and 45°C) on the fatty acid profiles quality of Kermanshahi roghan (yogurt by-product) and sour cream to obtain a formula for producing a kind of animal fat healthier than milk and cream. Stresses such as fermentation play an important role in bacterial behavior and consequently in food quality. Our findings presented a significant difference between roghan and sour cream fatty acid levels only at 37°C. Furthermore, starter culture 3 : 1 was the best starter for producing products with a higher quality of fatty acid profile at 37°C, and a 1 : 1 S. thermophilus to L. bulgaricus ratio was optimal at 45°C. It seems that bacteria adapt to harsh growth conditions by changing the fatty acid profiles, and these changes warrant consideration in the production of a kind of animal fat with the best fatty acid profiles. In conclusion, the roghan fatty acid profile is more suitable than sour cream only at 37°C.

Tempe is a fermented soybean food from Indonesia, made by inoculating Rhizopus spp. onto cooked and dehulled soybean. Tempe has been a part of Indonesian culture since the 16th century and is now produced globally as a highly nutritious plant-based food. Despite a longstanding history on the production of tempe, very few studies have been reported to understand the effect of raw material to the end product metabolite composition. In this research, we applied GC/MS-based metabolite profiling to investigate the effect of various possible factors that might affect the final product (environmental factors, raw materials, and starter cultures). Representative samples were tempe produced by Indonesian industries, Japanese industries as well as laboratory made tempe. The results showed that both environmental factors and raw materials (soybean, water, and starter culture) contributed to the tempe metabolite profile. Here we found the possibility that starter cultures might play a greater role to determine the metabolite profiles compared to other tested factors. This research might provide useful insights for the larger scale industries to maintain the quality of tempe for the benefit of the consumers.
