This work is concerned with the oxidative stability and sensory characteristics of traditional fermented sausage Petrovská klobása, produced with the addition of commercial starter culture (SC). Fatty acids profile, thiobarbituric acid-reactive substance (TBARS) values and sensory properties of odor and taste have been determined at the end of drying and after 2 and 5 months of storage. The sum of saturated, unsaturated and polyunsaturated fatty acids was not significantly different (P>0.05) in SC and control sausage at the end of storage. After 5 months of storage TBARS value of SC sausage amounted to 0.57 mg MDA/kg, and it was significantly lower (P

The effect of adding Staphylococcus xylosus on the oxidative stability and sensory properties of the traditional sausage (Petrovská klobása) subjected to industrial conditions of ripening was studied at day 0 and after 1 and 2 months of storage. During storage, TBARs values in sausages with added Staphylococcus xylosus ranged from 0.13 to 0.52mg malondialdehyde/kg significantly lower (p < 0.05) than those of control sausages. After 2 months storage, sensory properties of sausage with added Staphylococcus xylosus (4.52) was better compared to control sausage. Adding Staphylococcus xylosus can contribute to better oxidative and sensory stability of Petrovská klobása during storage.

Concentration of cadmium was investigated in the heart, tongue, lungs, spleen, liver, kidney, testis, brain and thymus of 15 Saanen goat male kids. This element was determined by inductively coupled plasma optical emission spectrometry (ICP-OES), after microwave digestion. The cadmium concentration was significantly influenced by the type of edible offal. Mean cadmium concentrations ranged from 0.018 mg/kg (heart) to 0.114 mg/kg (kidney). The maximum cadmium concentrations found in the kidney (0.133 mg/kg) and liver (0.075 mg/kg) were below maximum levels (1.0 and 0.5 mg/kg, respectively) set by legislation for these tissues.

The effects of pig breed (Large White and Landrace) in combination with muscle type ( M. semimembranosus and M. longissimus dorsi ) on T 45min , T 24h , pH 45min , pH 24h , colour (CIE L*a*b* values), water-holding capacity (filter paper press method: ratio of the area of pressed meat film – M and the wet area on the filter paper – T; M/T value) and moisture, protein, total fat and total ash content were investigated. Interaction effect between breed and muscle was not found ( p >0.05) for any parameter. The T 45min , T 24h , pH 45min , and M/T value were influenced by the muscle, whereas T 24h was also influenced by the breed. The pH 45min was higher ( p

The influence of drying and ripeninig conditions (traditional and industrial) in the production of dry fermented sausage Petrovská klobása, on fatty-acid composition and oxidative changes in lipids, during 7 months of storage, was investigated. During the storage period, the sum of unsaturated fatty acids and the content of free fatty acids were significantly higher (p

A study was carried out on traditional Serbian dry-fermented sausage Petrovská klobása in order to investigate the effect of different ripening conditions and use of starter culture (SC) on drying characteristics of this typical meat product. The results related with reduction of diameter, water activity (aw) and moisture content of sausages, obtained during ripening, indicated 30 days faster drying process in controlled industrial ripening room (RR) than in traditional room (TR) (60 vs. 90 days). Along with the ambient (thermo-hygrometric) conditions, this phenomenon was also determined by pH, which was lower in RR sausages (P0.992) indicate good fit of the experimental data (average moisture content vs. drying time) using third degree polynomial equation, both for RR and TR sausages, whether the samples were produced with or without SC. Additionally, the evolution of moisture content ratio between internal and external fractions of sausages indicated more intense drying in the external ones. This was particularly pronounced in sausages made with SC after 30 days of drying. The use of SC and RR in processing of Petrovská klobása seems to be a potential technological improvement to shorten the drying period and to prolong the production season of this traditional meat product.

Chitosan, the second most abundant polysaccharide in nature, after cellulose, has been tested for numerous applications, among which for edible film and coating. Chitosan-based coating showed positive results for shelf life prolongation of meet products. In this paper, dry fermented sausage (Petrovska klobasa) was coated with chitosan-caraway film. The effect of coating on the moisture content, color and lipid oxidation was investigated during a fivemonth period of storage. The moisture content decreased rapidly during the storage and the coating did not slow down the loss of moisture. The Lightness (L*) of the sausage surface increased by the coating application, while the redness (a*) and yellowness (b*) did not change. The coated sausages showed a better color stability of the sausage core through the storage time. Also, coated sausage showed a better oxidative stability till the 60th day of storage, while this difference was not detected at the end of the storage period. Apart from slowing down sausage drying during the storage, chitosan-caraway coating was effective in preserving the sausage quality. [Projekat Ministarstva nauke Republike Srbije, br. TR31032]

Quality parameters including sensory and physical characteristics and proximate and mineral composition in M. psoas major, M. semimembranosus, M. longissimus thoracis et lumborum and M. triceps brachii of Swallow-Belly Mangulica pigs were determined. Type of muscles had no significant effect (P>0.05) on water-holding capacity, protein, total fat, K, P and Ca content. The M. psoas major was the highest in pH24h, water-holding capacity, CIEa* and CIEb* values, moisture, K, P aQuality parameters including sensory and physical characteristics and proximate and mineral composition in M. psoas major, M. semimembranosus, M. longissimus thoracis et lumborum and M. triceps brachii of Swallow-Belly Mangulica pigs were determined. Type of muscles had no significant effect (P>0.05) on water-holding capacity, protein, total fat, K, P and Ca content. The M. psoas major was the highest in pH24h, water-holding capacity, CIEa* and CIEb* values, moisture, K, P and Cu content, and the lowest in visual marbling score and total fat content. The M. semimembranosus was the highest in Mg and Ca content, and the lowest in CIEL* value (darkest muscle) and K content. The lightest colour (CIEL* value), the highest content of protein, total fat and total ash, and the lowest visual colour score, pH24h, CIEa* and CIEb* values, content of moisture, Na, Ca, Zn, Fe and Cu were found in M. longissimus thoracis et lumborum. The highest visual colour and marbling score, the highest content of Na, Zn and Fe, and the lowest water-holding capacity, content of protein, total ash, P and Mg were found in M. triceps brachii.

The effect of different ripening processes (traditional, T vs. industrial, I) on proteolytic changes and texture of dry-fermented sausage Petrovská klobása was examined. More intensive pH decline was registered in I sausages, which had a positive impact on the drying process and proteolysis. Moisture content in I sausages was consistently lower than in T sausages. Likewise, proteolysis was more pronounced in I sausages, resulting in higher concentrations of nitrogen fractions. During processing, hardness and chewiness were significantly higher in I sausages, but these became almost identical once the required moisture content of sausages (

The aim of this paper was to determine the content of vasoactive biogenic amines in Sremski kulen and Sremska kobasica and to estimate hygienic conditions and good manufacturing practice (GMP) according to proposed criteria. Formation of dansyl chloride derivatizated vasoactive amines were determined using HPLC–DAD. Tryptamine (47.6; 34.2mg/kg), histamine (16.1; 6.42mg/kg) and tyramine (95.1; 45.2mg/kg) were detected in both investigated type of traditional dry fermented sausages while phenylethylamine was not detected. Total content of vasoactive amines did not exceed the sum (200mg/kg) proposed as a possible indicator of hygienic conditions and GMP in sausage production.
