Effect Of Biopreservative Cultures On The Shelf Life Of Modified Atmosphere Packaged Chicken Cocktail Sausage, Sevgi̇ Ataş, Gökhan Kürşad İnci̇li̇, Hali̇l Durmuşoğlu, Mehmet Çalicioğlu

Turkish Journal of Veterinary & Animal Sciences

The present study was undertaken to extend the shelf life of modified atmosphere packaged chicken cocktail sausages by using biopreservative cultures (Lactobacillus sakei (B-2) and Lactobacillus curvatus (B-LC-48)). According to the results, cocktail sausages in control group stored either at 4 °C or 10 °C were spoiled as of day 28 due to a decrease in average flavor score and general acceptance score and increases in mesophilic and psychrotrophic colony counts (p < 0.05). In bioprotective cultures treated groups, no spoilage was detected throughout the 60-day storage at 4 °C, whereas those products stored at 10 °C spoiled as of day 42. Results of this study indicated that the bioprotective cultures tested were able to control the spoilage bacteria by establishing bacterial predominance starting from the first day of the shelf life (p < 0.05). It was concluded that these cultures can be useful in chicken cocktail sausages production, especially when a proper cold chain cannot be guaranteed during transportation and at retail.

Expression of late embryogenesis abundant (LEA) proteins is highly correlated with desiccation tolerance in anhydrobiotic animals, selected land plants, and bacteria. Genes encoding two LEA proteins, one localized to the cytoplasm/nucleus (AfrLEA2) and one targeted to mitochondria (AfrLEA3m), were stably transfected into human HepG2 cells. A trehalose transporterwas used for intracellular loading of this disaccharide. Cellswere rapidly and uniformly desiccated to low water content (<0.12 g H2O/g dry weight) with a recently developed spin-drying technique. Immediately on rehydration, control cells without LEA proteins or trehalose exhibited 0% membrane integrity, comparedwith 98% in cells loaded with trehalose and expressing AfrLEA2 or AfrLEA3m; surprisingly, AfrLEA3m without trehalose conferred 94% protection. Cell proliferation across 7 d showed an 18-fold increase for cells dried with AfrLEA3m and trehalose, compared with 27-fold for nondried controls. LEA proteins dramatically enhance desiccation tolerance in mammalian cells and offer the opportunity for engineering biostability in the dried state.
