This study aimed to investigate the influence of substitution of milk fat with palm fat on the composition, yield and technological quality of White cheese, a Macedonian traditional cheese. In this study, fullfat white brined cheese was used as a control sample (WC), while experimental cheeses were prepared from cow milk with vegetable fat (WV) addition and low-fat cheese (WL), respectively. The cheeses have been analysed for physicochemical (acidity, pH, fat, fat acidity, protein), instrumental texture and colour properties (L, a, b) as well as the sensory properties after 1, 20 and 60 days. WV cheeses showed a significantly (P<0.05) lower degree of pH and higher titratable acidity than the WC and WL cheese samples. Cheese that contained vegetable fat showed lower degrees of lipolysis, as assessed by the acid-degree value and received significantly (P<0.05) better appearance, highest hardness value (5226.98 N) and cheese yield scores compared to other samples.

The aim of this study was to test the effects of various spices on the physicochemical and sensory properties of white cheese. Six different white cheeses were produced by incorporating the spices of black cumin, mint, thyme, red pepper and isot pepper at a ratio of 3 % (w/v) of the cheese milk. All cheeses were vacuum-packed and ripened at 4±1°C. On the 2nd, 15th, 30th, 60th and 90th days of ripening, dry matter, fat, pH, titratable acidity, salt, total proteins, ripening index, non-protein nitrogen rate, amino nitrogen rate, electrophoretic casein fractions, textural and sensory properties were determined. Isot pepper and black cumin increased the proteolysis rates of white cheeses with higher degradation rates on β-casein fraction, indicating that these cheese samples had more pronounced ripening. On the other hand, thyme and isot pepper were more effective on αs1-casein fraction. All tested spices, except isot pepper, contributed to the sensory properties of white cheeses, by increasing the consumer acceptance. This study reveals spice addition had positive effects on chemical, biochemical and sensory characteristics of white cheese, and thus, white cheese with spice addition is an alternative novel product with a good potential.

The effect of adding different concentrations of Jerusalem artichoke (Helianthus tuberosus) extract on the quality of low-fat yoghurt was studied. 10, 15, 20 ml of the Jerusalem artichoke (Helianthus tuberosus) extract was added to the pasteurized liquid milk contain 0.1% milk fat to purpose of giving different levels of inulin/ µg (each milliliter from Jerusalem artichoke (Helianthus tuberosus) extract contains 21 µg of inulin). The yoghurt samples were compared with the control sample produced from whole fat milk. The content of total solids in milk was adjusted to 14% by adding skim milk powder. After storage periods 1, 7, and 15 days, the chemical-physical composition of the yoghurt samples, such as pH, titratable acidity, syneresis (whey separation), the amount of acetaldehyde, and volatile fatty acids. The sensory characteristics of the samples were also evaluated during the same storage periods. It was found that the addition of Jerusalem artichoke extract containing more than 210 µg caused in increased separation of whey and consistency. The values of acetaldehyde, PH and titratable acidity were not affected by adding the Jerusalem artichoke extract. volatile fatty acid levels were affected negative. In the case of sensory evaluation of yogurt. The addition of Jerusalem artichoke extract resulted in the retention of the sensory quality grades, where the treatment control was highest, and the lowest grade was obtained in the yoghurt samples containing 420 μg of inulin. Overall, the quality characteristics of the yoghurt containing 210 μg inulin was similar to the quality characteristics of the control like yoghurt made from whole milk.

Purpose The purpose of this study is to evaluate the effects of partial or total substitution of milk fat by various levels of jojoba oil on the nutritional, physicochemical and sensory properties of Domiati cheese during cold storage at 6°C for 45 days. Design/methodology/approach The fat percentage of milk used for cheese manufacture was standardized to 4% fat. Five formulas were produced by replacing milk fat with 0%, 25%, 50%, 75% and 100% of jojoba oil, respectively. The physicochemical and sensory properties of cheese samples at 0, 15, 30 and 45th days of cold store were evaluated. Findings No significant differences in moisture, fat, protein and acidity values amongst the control samples and those samples supplemented with different concentrations of jojoba oil. Significant differences (p = 0.05) in total volatile fatty acids were detected amongst experimental cheese samples. The highest values were recorded for control sample containing 100% milk fat, while the lowest values were recorded for cheese sample containing 100% jojoba oil (p = 0.05). Total nitrogen (TN), water-soluble nitrogen (WSN) and trichloroacetic acid soluble nitrogen (TCA-SN) levels of experimental cheeses were nearly same as for control. The results of fatty acids profile showed that jojoba oil has a unique structure of straight monounsaturated alcohols. Significantly (p = 0.05), the highest cholesterol content was recorded for control sample containing 100% milk fat; however, the lowest (p = 0.05) value was recorded for cheese sample containing 100% jojoba oil. At the end time of storage period, control sample manufactured with 100% milk fat had the highest (p = 0.05) values of free fatty acids, peroxide and thiobarbituric acid, while the lowest values were recorded for cheese sample with 100% jojoba oil as a source of fat. The sensory evaluation results demonstrated that blending milk fat with jojoba oil improved the sensory properties of Domiati cheese. Practical implications It is concluded that substitution of 25%, 50%, 75% and 100% of milk fat by equal amounts of jojoba oil enhanced the nutritional and sensory characteristics of Domiati cheese. Originality/value It is concluded that Domiati cheese formulated with substitution of 25%, 50%, 75% and 100% of milk fat by equal amounts of jojoba oil enhanced the nutritional characteristics and improved the sensory properties of produced cheese.

AbstractIn the worldwide, the consumption of traditional coffees has been widely increased due to their distinctive aroma. Turpentine coffee (TC), known as “menengic coffee” is one of the most consumed coffees in the Turkey. The aim of this study was to produce a new and functional yoghurt using different concentrations of TC (0.5, 1 and 2%) and evaluated the effect of TC addition on the physicochemical and microbiological properties, colour values, organic acid profiles and sensory parameters of yoghurts during 21 days of storage at ±4 °C. The ash, protein, fat, viscosity, syneresis, titratable acidity and pH values, a* and b* colour properties, orotic, citric, lactic, acetic, butyric and propionic acid levels of yoghurts showed an increase with the increment of TC amount, while total solids, Lactobacillus delbrueckii spp. bulgaricus, Streptococcus thermophilus and yeast-mould counts, L* colour value, pyruvic acid amount and all observed sensory properties of yoghurts decreased. Total solids, ash, protein and syneresis values, L. bulgaricus and S. thermophilus counts, L*, a* and b* colour parameters, appearance scores of yoghurts have shown almost similar changing during storage. Generally, all observed parameters showed statistically significant differences (P < 0.01; P < 0.05) with the addition of TC except for syneresis value, orotic, pyruvic, butyric and malic acid concentrations.

Introduction. Fruits and vegetables are vital for healthy food consumption. Conservation is the only option to prolong their shelf life. Nigeria is currently experiencing an increase in production of fruit jams that incorporate vegetables. Cucumbers, Jatropha tanjorensis L. leaf, and pineapples have a lot of health benefits, which makes them very promising for jam making. The present research featured the effect of cucumber, pineapple, and Jatropha leaf in different proportions on the functional and sensory properties of composite jam. Study objects and methods. The technology of jam making followed standard procedures. Pineapple jam without cucumbers and Jatropha leaf served as control (pineapple:cucumber:Jatropha leaf = 100:0:0). The experimental jam samples had increasing amounts of Jatropha leaf (J), decreasing amounts of pineapple pulps (P), and a constant amount of cucumber (C), i.e. P:C:J = 85:10:5, 80:10:10, 75:10:15, and 70:10:20. The functional analysis involved chemical and proximate aspects, whereas the sensory evaluation involved appearance, aroma, taste, spreadability, and overall liking. Results and discussion. The experimental samples showed a significant difference (P < 0.05) in vitamins, minerals, total titratable acidity, pH, Brix, and total soluble solids. The control sample (P:C:J = 100:0:0) had significantly lower (P < 0.05) contents of moisture, protein, ash, fat, and fiber than the experimental ones. However, the pH and total titratable acidity of the experimental samples 85:10:5 and 80:10:10 appeared to be quite similar (P > 0.05). Compared to the control sample, the sensory properties of the experimental samples differed significantly (P < 0.05) by appearance, aroma, and spreadability but were of similar (P > 0.05) taste and overall liking. Conclusion. The obtained functional and sensory data proved that the new pineapple jam with cucumber and Jatropha leaf is a promising functional product.

The authors proposed a milk-containing product with a substitute for milk fat, produced according to the technology of sour cream using a protective culture in order to prolong the shelf life. The use of protective starter cultures does not require additional equipment or changes in technological parameters. The protective culture is introduced along with the main sourdough and works according to the traditional principle of fermentation, as well as through competitive exclusion, i.e. taking up space and reducing the possibility for the growth of yeast, molds and BGKP. Two developments of a milk-containing product were carried out - the first using a protective culture (experimental sample), the second without using a protective culture (control sample). The products are stored for 40 days at a temperature of 4 ± 2 °C. In the control sample, on day 30, yeast growth, deterioration in organoleptic indices, increase in titratable acidity were observed, on day 40, the product was considered spoiled. In the experimental sample, organoleptic, physicochemical and microbiological parameters during storage were within normal limits. The shelf life of a milk-containing product with a milk fat substitute produced using the technology of sour cream is determined using a protective culture taking into account a safety factor of 30 days. An increase in the shelf life of the latter by 30% was established in comparison with the control sample.

The aim of this study was to assess the relationship between temperament and milk performance in cows at different stages of lactation, describing their productivity, metabolic status and resistance to mastitis. This study showed that with increasing lactation, cows’ temperament indicators decreased (p < 0.001) and they became calmer. The highest temperament score on a five-point scale was found in cows between 45 and 100 days of lactation. In the group of pregnant cows, we found more cows (p = 0.005) with a temperament score of 1–2 compared with non-pregnant cows A normal temperament was usually detected in cows with lactose levels in milk of 4.60% or more and when the somatic cell count (SCC) values in cow milk were <100,000/mL and 100,000–200,000/mL, with a milk fat-to-protein ratio of 1.2. A larger number of more sensitive and highly aggressive cows was detected at a low milk urea level. In contrast to a positive phenotypic correlation (p < 0.05), this study showed a negative genetic correlation between the temperament of cows and milk yield (p < 0.001). Positive genetic correlations between temperament scores and milk somatic cells (p < 0.001) and milk fat-to-protein ratio (p < 0.05) were found to indicate a lower genetic predisposition in cows with a calmer temperament to subclinical mastitis and ketosis. On the other hand, the heritability of temperament (h2 = 0.044–0.100) showed that only a small part of the phenotypic changes in this indicator is associated with genetic factors.
