Abstract. To compare quality traits of longissimus lumborum muscle of three genotypes, 20 White Mangalica (WM), 20 crossbred Duroc  ×  White Mangalica (DWM) and 20 Large White (LW) pigs were allotted to the same indoor rearing and feeding conditions. Crossbred and LW pigs grew faster than WM pigs reaching 150 kg on average 168 and 288 days before WM, respectively. Meat from WM pigs had the highest intramuscular fat content and darkest and reddest colour; crosses were at an intermediate position, with significant differences among all genotypes. In addition, ultimate pH, water-holding capacity and iron content were significantly the highest in meat from WM pigs, compared to the other two genotypes. Crossing WM with Duroc had a significant effect on individual fatty acid content of meat. However, the sum of saturated, monounsaturated and polyunsaturated fatty acids remained unchanged. WM and DWM pigs had significantly more tender meat than LW pigs. Monounsaturated fatty acids (MUFAs) were most abundant, followed by saturated (SFAs) and polyunsaturated fatty acids (PUFAs) in meat from all animals. Meat from WM and DWM pigs had a significantly higher percentage of MUFAs and significantly lower percentage of SFAs than LW pigs.

Kranjska klobasa is a traditional Slovenian cured, smoked, and cooked sausage made with coarse‐ground pork. It is a traditional product that is protected geographical indication status and is produced practically everywhere in Slovenia, as well as in some other European countries. The aim of this study was to determine the main characteristics of Kranjska klobasa prepared by different manufacturers in Slovenia. Products from 14 producers were analysed for basic chemical composition, for content of salt, nitrite, phosphate, and TBARs, for instrumentally measured firmness, and for sensory parameters. A comparison of some of these characteristics of Kranjska klobasa produced over the last 12 years was also carried out. Despite some of the limitations (less added pork fat, free of added phosphates, and beef), the Kranjska klobasa with protected geographical indication status shows better juiciness, texture, intensity of flavor, and overall acceptability compared to Kranjska klobasa produced before protection was granted. Practical applications It is well known that protection of quality traditional food products can promote specific rural areas. Therefore product characterization is essential for success and recognition in the market. In this article is shown that protection has changed and standardized the composition and manufacturing process of Kranjska klobasa with protected geographical indication status. Protected product showed better juiciness, optimal texture, intense flavor, and improved overall acceptability compared to the Kranjska klobasa “before protection.” Even with some limitations (use of beef, polyphosphates, and meat batter is prohibited, pepper and garlic permitted spices), decreased content of fat (limited to 29%) improved sensory quality for the product can be provide.

Consumers often mix pasteurised meat products from the subgroup of smoked meat with a subgroup of meat products known as canned meat. The aim of this study was therefore to determine their physicochemical parameters and sensory properties of smoked meat and canned meat subgroups of pasteurised meat products on the Slovenian market. Chemical analyses of the content of ash, sodium chloride and phosphates, thiobarbituric acid number (TBA), instrumental measurements of the proximate composition (NIR), colour (CIE L*, a*, b*) and texture (Texture Profile Analysis) as well as the evaluation of sensory properties (Descriptive Analysis Method) were performed on 33 products. The products of smoked meat had a higher content of protein, ash, total phosphates and sodium chloride than the products of canned meat. All products were oxidatively stable (low TBA number). The products of smoked meat were darker (lower L* values) and redder in cross-section (higher a* values), they were tougher, gummier, more difficult to chew, more cohesive and less elastic in texture (Texture Profile Analysis) than the products of canned meat. The panel of experts evaluated the products of both subgroups with a similar average overall impression. Compared to the products of the canned meat, the products of the smoked meat showed worse slice colour uniformity, they contained a higher level of gelatinised connective tissue on the slice, had a worse slice connectivity, the texture of a slice was firmer with coarser fibres, they were saltier, with a less pronounced metallic and rancid aroma and a more pronounced bitter, acidic and odd aroma. Chewiness, gumminess, cohesiveness, hardness and elasticity (texture parameters) loaded strongly on the quality parameters of all products (Factor analysis). Furthermore, linear discriminant analysis confirmed that the products of the subgroups smoked meat and canned meat differ in their physico-chemical and sensory profile.

Suha klobasa is a popular dry-cured sausage that is produced practically everywhere in Slovenia. The aim of this study was to investigate the main characteristics of Suha klobasa produced by different manufacturers across five different informal regions of Slovenia. Products from 31 producers, as households (11), small workshops (15) or industrial plants (3) were analysed for pH value, moisture, protein, fat, and ash, as well as for their sensory parameters, according to assessments of four profiles: appearance, texture, smell and aroma. Technological production procedures were evaluated on the basis of a survey. In average Slovenian Suha klobasa pork is used, also Suha klobasa is characterized by slow ripening and smoking or without smoking but overgrown with mould. It is always filled in a small diameter casings (32-34 mm) of the pig small intestine or permeable casings, formed in two equal-length-halves and on one side (open side) looped around, often with a wooden stick. According to the regions of Slovenia, several types of Suha klobasa can be distinguish that are defined by sausage length and surface colour, mosaic and porousness on the one hand, and acid, smoke, mould, rancid smell/aroma on the other. Suha klobasa originated from different manufacturing practices differ in visual characteristics of product (size, equality and mould), in cross-section (mosaic, porousness and glassines), and texture (hardness, toughness and integrity) but not in olfactory and aroma profile.

The aim was to determine the quality parameters and oxidative stability of colour, lipids and proteins (formation of carbonyls) of vacuum packed lamb at a constant temperature of 2 °C ±1 °C up to 15 days post mortem. The suitability of lamb loin (longissimus lumborum) for ageing and optimal ageing period to obtain optimum sensory properties, especially tenderness and aroma was determined. A sample of 100 g lamb meat contains 23.48 g protein, 69.66 g water and 5.48 g fat. Lamb samples were the most tender after 11 days (both, sensory assessed and instrumentally measured – share force decreased by 61%) and had the best aroma after 15 days post mortem. In the meantime, the lamb became significantly brighter and more saturated (higher L*, a* and b* values), the content of secondary lipid oxidation products increased (1.7 times higher amount of malondialdehyde), and the content of protein carbonyls decreased to the initial value, despite an initial increase observed 11 days post mortem. We found that lamb loin is suitable piece for ageing; the optimal duration of ageing of loins is 15 days post mortem.
