Effects of Drying Methods on Chemical Composition, Lipid Oxidation, and Fatty Acid Profile of a Traditional Dried Meat Kaddid.

This work aimed to study the effect of three drying methods, namely sun-drying (SD) (T = 32 °C), continuous convective drying (CCD) (T = 35 ± 2 °C) and interval starting accessibility Drying (ISAD) (T = 35 ± 2 °C) with an active time of 30 s (t) and a tempering time of 60 s (t), on selected quality characteristics of a traditional dry-salted meat product known as "kaddid". The analyses of chemical composition, lipid oxidation and fatty acid profile of kaddid were carried out before and after 45 days of storage (t = 0 vs. t = 45) at ambient temperature.

Physicochemical Characteristics, Fatty Acid Profile, Alpha-Tocopherol Content, and Lipid Oxidation of Meat from Ewes Fed Different Levels of Distilled Myrtle Residues.

The aim of this work was to study the sheep meat physicochemical traits as affected by distilled myrtle residues (MR) supplementation. For this, 27 culled ewes were divided into three groups receiving a ration composed by concentrate and hay for the Control group, concentrate and MR as a total substitute to hay for the Myrt-H group, or hay, less concentrate, and MR as a partial substitute to concentrate for the Myrt-C group. The meat chemical composition, pH, and color parameters were not affected by the MR intake.

The effect of Rosemary (Rosmarinus officinalis L.) distillation residues and linseed supply on fatty acid profile, meat colour, lipid oxidation and sensorial and hygienic quality of cull Barbarine ewes' meat.

To test the hypothesis that feeding cull ewes with Rosemary (Rosmarinus officinalis L.) distillation residues (RR) and linseed improves meat quality traits; fatty acid (FA) profile, lipid oxidation, meat colour, sensory and microbiological analysis were investigated. For this, 28 Barbarine ewes received 500 g of basal diet and 700 g of concentrate.

Use of pomegranate peel and artichoke leaf extracts to improve the quality of marinated sardine () fillets.

Effects of pomegranate peel and artichoke leaf aqueous extracts on biochemical, microbiological and sensorial quality of sardine fillets was investigated during marination and storage for 90 days. Sardine fillets were marinated with 4% acetic acid, 10% NaCl and either 5% pomegranate peel extracts or 5% artichoke leaf extracts. The control sample was marinated with only 4% acetic acid and 10% NaCl.

Technological and safety properties of Lactobacillus plantarum strains isolated from a Tunisian traditional salted meat.

A total of 17 strains of Lactobacillus plantarum, isolated from a Tunisian traditional salted meat and identified by biochemical and molecular methods, were characterized according to their technological properties including acidifying, antimicrobial and enzymatic activities as well as antibiotic resistance in order to select the most suitable for use as starter cultures for the production of fermented sausages. All the strains studied showed good acidifying activity and were able to reduce the pH to less than 4.3 in 72, 48 and 24h at 15, 25 and 37°C respectively.

Characterization and technological properties of Staphylococcus xylosus strains isolated from a Tunisian traditional salted meat.

The technological properties of strains of Staphylococcus xylosus were studied to select the most suitable for use as starter cultures for the production of dried fermented meat products. Strains of S. xylosus were isolated from traditional salted Tunisian meat and were identified by biochemical and molecular methods.
