Investigation of physicochemical and sensorial quality of a type of traditional meat product: Bez sucuk

Influence of pre-treated bitter orange albedo on the physicochemical, textural and sensory properties of fermented sausages (sucuk)

The aim of this study was to determine the physicochemical (pH, water activity, titratable acidity, moisture, protein, fat, colour, weight loss and oxidative stability), textural and sensory properties, and the growth of lactic acid bacteria in fermented sausages (sucuk) supplemented with different levels (0, 1, 2.5 and 5.0%) of pre-treated bitter orange (Citrus aurantium) albedo. Results indicated that adding albedo to sucuk samples increased (P < 0.01) the titratable acidity, lightness and yellowness values; while it led to a decrease (P < 0.01) in pH and weight loss values. Moreover, it was observed that there were increases (P < 0.05) in Thiobarbituric acid (TBA) values when albedo was added to the samples. The highest lactic acid bacteria count was observed in the sucuk samples supplemented with 5% albedo. Regarding textural properties, albedo addition increased (P < 0.01) hardness, springiness, gumminess and chewiness values. Lastly, sensory analysis results showed that albedo added sucuk samples generally got higher (P < 0.05) scores from panellists compared to control samples.

Application of Fat-Tailed Sheep Tail and Backfat to Develop Novel Warthog Cabanossi with Distinct Sensory Attributes

This study compared the use of pork backfat (PF) and fat-tailed sheep tail and backfat (SF) on the physicochemical, fatty acids and sensory attributes of warthog cabanossi. There were no differences between weight loss during drying, moisture content, pH, water activity, salt content and lipid oxidation between the cabanossi types. However, protein and ash contents were higher in PF cabanossi whilst fat content was higher in SF cabanossi. The PF cabanossi had higher polyunsaturated fatty acids (especially n-6), lower monounsaturated fatty acids whilst the saturated fatty acid content was similar between the two cabanossi products. The n-3:n-6 ratio was more beneficial in the SF cabanossi. The descriptive sensory analysis showed two distinct products where PF cabanossi scored higher for most attributes. Although SF cabanossi scored less for these attributes, this cabanossi had unique and acceptable sensory attributes. This study concluded that fat-tailed sheep tail and backfat could be used to produce a unique cabanossi product of acceptable quality.

Fermented meat sausages from game and venison: what are the opportunities and limitations?

An increase in the acceptance, demand and production of game meat and venison has been experienced globally. Game meat and venison fit into consumers' ideology of healthy and environmentally friendly meat when compared to domesticated animals. Opportunities exist to explore the use of these meat sources in developing new products, particularly as game meat and venison in their fresh state are sometimes perceived as being tough. Consumers have shown a trend for trying exciting new products with different organoleptic qualities, and fermented sausages occupy a special niche in the gastro-economic trade. In this review, the production potential of game meat and venison and its prospective use in the development of fermented sausages are discussed. Emphasis is placed on the importance of meat characteristics in textural and sensorial development as well as the safety of fermented sausages. Additionally, consumers' perception of venison and game meat is discussed. Possible areas of research and knowledge gaps are highlighted, particularly the potential use of meat with high pH and microbial load. © 2018 Society of Chemical Industry.

Safety, Quality and Analytical Authentication of ḥalāl Meat Products, with Particular Emphasis on Salami: A Review

Only some animal species could be transformed into ḥalāl salami and the raw meat must be obtained from ritually slaughtered animals. Several scientific studies have been conducted on ritual slaughtering practices and manufacturing of meat products for Jewish and Muslim religious communities; furthermore, many projects have been funded by the European Community on this topic. The authenticity and traceability of meat is one of the priorities of ḥalāl food certification systems. The pig matrix (meat and/or lard) may be fraudulently present in ḥalāl processed meat, as well as salami, for both economic and technological purposes; in fact, the use of these raw materials reflects the easier availability and their lower cost; furthermore, it allows manufacturers to obtain final products with better quality (sensory properties) and stability (especially with respect to oxidative reactions). The aim of this review is to discuss the qualitative and technological aspects of ḥalāl raw meat for dry fermented sausages (salami); moreover, this study focuses on the most recent studies carried out on the certification system and on the analytical methods performed in order to solve problems such as fraud and adulteration of ḥalāl salami and other halal meat foods.

Changes in Lipid Oxidation and Fatty Acids in Altay Sheep Fat during a Long Time of Low Temperature Storage

Previously, we have shown that the fatty acid composition of Altay sheep tail fat is of reasonable value and is suitable for further development of possible commercial products. Changes in lipids of Altay sheep tail fat during 50 days of 4°C refrigerated storage were investigated. Lipid oxidation and lipolysis occurred during the storage. The pH showed a continually decreased from first day to the end of the storage (p < 0.05). The lipid oxidation was determined by peroxide value (PV) and thiobarbituric acid-reactive substances (TBARS). The increase PV was observed in Altay sheep fat up to 24 days of storage and decreased from then to the day 30 (p < 0.05). The increase in TBARS was significantly throughout the refrigerated storage (p < 0.05). The changes of the fatty acids identified by GS-MS demonstrated that saturated fatty acids increased from 43.6% to 56.3% and that polyunsaturated fatty acids and monounsaturated fatty acids decreased form 51.2% to 43.7% and from 2.4% to 2.1%, respectively. The content of the functional fatty acids except (C18:2 n-9), started to decrease after 20 days of storage. Those changes indicated that lipid oxidation occurred in Altay sheep tail fat during a long time of low temperature storage. In addition, the good correlation between PV/TBARS values and changes of individual fatty acids could be used as an indicator to monitor the changes of the unsaturated fatty acid during the development process of Altay sheep tail fat-related commercial products.
