Leuconostoc Carnosum

The effect of taxifolin (TXF) with starter cultures (SC), such as Leuconostoc carnosum, or a mixture of  strains Pediococcus pentosaceus and Staphylococcus xylosus, on the TXF stability was evaluated. UPLC analysis demonstrated that after 181 days of storage total TXF content was the highest in samples with TXF and L. carnosum (60%), compared to the 1st day of storage. The sausages with TXF and the mixture of P. pentosaceus and S. xylosus (56%) followed next. The samples treated only with TXF retained 40% of TXF, compared to the 1st day of storage. TXF had no significant effect on the growth of lactic acid bacteria. The accumulation of biogenic amines (BA), including histamine and putrescine, was more effectively reduced in sausages inoculated with the TXF plus P. pentosaceus and S. xylosus mixture. Using this mixture, the rate of lipolysis and processes of lipid oxidation were effectively slowed down. Fatty acid (FA) composition was stable in all cases.

The aim of this study was to determine the effect of sodium lactate addition on shelf-life extension of sliced poultry sausage packaged both in air and nitrogen atmospheres and stored in refrigerated conditions. Basic chemical composition, pH, and malonaldehyde content were assayed and color measurement using the reflection method was carried out. Microbiological examination consisted of determination of total number of aerobic psychrotrophic bacteria and number of lactic acid bacteria. Sensory evaluation of products was performed. Microbiological and sensory quality of sliced poultry meat sausage was dependent on the addition during production of sodium lactate and the composition of gases (air or nitrogen) used in packaging. Slices of poultry sausage with 1% as well as 2% of sodium lactate maintained their initial quality of evaluated sensory attributes longer, irrespective of the applied gases. Sodium lactate inhibited growth of aerobic psychrotrophic bacteria and lactic acid bacteria during refrigerated storage. Sodium lactate also inhibited the formation of malonaldehyde in sliced poultry sausage during refrigerated storage. The effectiveness of this process depended on the concentration of sodium lactate addition. It was concluded that 1% as well as 2% addition of sodium lactate could extend the shelf life of sliced poultry sausage packaged in air atmosphere and stored at 5 to 7°C by 3 or 4 times, respectively. Sliced poultry sausage treated with 2% sodium lactate packed in nitrogen had the longest (35-day) shelf life. This was a sevenfold increase in the shelf life of sliced poultry sausage compared with the control.

Bacon prepared with 40 and 80 mg/kg (ppm) sodium nitrite, 0.7% sucrose and a culture of Pediococcus acidilactici (Wisconsin Process), and control bacon prepared with 120 ppm sodium nitrite and no added sucrose or bacterial culture were produced at three commercial bacon production plants. Sodium chloride, phosphate and sodium ascorbate (or sodium erythorbate) levels, as well as other processing conditions such as pumping rate, smokehouse temperature and time, forming and slicing conditions, were those normally used by each plant. Randomly selected samples of each lot were used for a challenge experiment with Clostridium botulinum (types A and B), with ca. 1,000 heat-shocked spores/g of bacon inoculated on each slice, vacuum packaged and incubated at 27°C. Samples were taken periodically up to 56 d of incubation and examined for the presence of botulinal toxin. The challenge experiment revealed that test bacon was substantially greater in antibotulinal properties than the control bacon. Residual nitrite levels of test bacon were lower than those of the control bacon, as were nitrosamines formed upon frying. Average N-nitrospyrrolidine level was 8.6 μg/kg (ppb) in the control, <2.7 ppb in the 80-ppm nitrite product, and <1.6 ppb in the 40-ppm nitrite product. This study indicates that bacon commercially prepared by the Wisconsin Process with 40 or 80 ppm sodium nitrite has a lesser risk of nitrosamine and botulinal toxin formation than bacon prepared with 120 ppm sodium nitrite and no added sucrose and lactic acid bacteria.

Saponins are a class of glycosides whose aglycones can be either triterpenes or helical spirostanes. It is commonly recognized that these active ingredients are widely found in various kinds of advanced plants. Rare saponins, a special type of the saponins class, are able to enhance bidirectional immune regulation and memory, and have anti-lipid oxidation, anticancer, and antifatigue capabilities, but they are infrequent in nature. Moreover, the in vivo absorption rate of saponins is exceedingly low, which restricts their functions. Under such circumstances, the biotransformation of these ingredients from normal saponins—which are not be easily adsorbed by human bodies—is preferred nowadays. This process has multiple advantages, including strong specificity, mild conditions, and fewer byproducts. In this paper, the biotransformation of natural saponins—such as ginsenoside, gypenoside, glycyrrhizin, saikosaponin, dioscin, timosaponin, astragaloside and ardipusilloside—through microorganisms (Aspergillus sp., lactic acid bacteria, bacilli, and intestinal microbes) will be reviewed and prospected.

Inhibitory Efficiency

The effect of antimicrobials produced by lactic acid bacteria (LAB) on the inhibition of Listeria monocytogenes ATCC 19111 in minced salmon was analysed and compared to the sodium lactate and bacteriophage action during storage at 6 °C. All tested additives showed a quite noticeable reduction of L. monocytogenes counts by 30–95% compared with control samples. Antimicrobials produced by the tested Enterococcus faecium strains showed moderate inhibitory activity while the greatest inhibitory activity was observed for antimicrobials produced by Streptococcus thermophilus 43 directly in the same way as the additive sodium lactate. The correlation was determined within inhibitory efficiency and produced total fatty acid amounts. S. thermophilus 43 showed the exceptionally stronger inhibition index for L. monocytogenes and yielded the higher monounsaturated fatty acid amount (42%) than E. faecium strains. Both E. faecium strains showing the lower inhibition efficiency produced the highest polyunsaturated fatty acid amounts (21.7–29.5%). E. faecium L41-2B-2v and S. thermophilus 43 were found to produce bioactive compounds like omega-3 and omega-6 FAs.

Herb Extract

Two spice and herb extract combinations from galangal (Alpinia galanga), rosemary (Rosmarinus officinalis), and lemon iron bark (Eucalyptus staigerana) were evaluated for their ability to inhibit the growth of inoculated Listeria monocytogenes and Staphylococcus aureus and naturally present spoilage microflora on cooked ready-to-eat shrimp stored for 16 days at 4 or 8°C. A combination of galangal, rosemary, and lemon iron bark significantly reduced (P < 0.05) levels of aerobic bacteria and lactic acid bacteria at 4°C on day 12 by 1.6 and 1.59 log CFU/g, respectively. By day 16, levels of these bacteria were equivalent to those of controls. The shrimp treated with this spice and herb extract combination had significantly lower (P < 0.05) lipid oxidation from day 4 to day 16. Similarly, a combination of galangal and rosemary extract significantly reduced (P < 0.05) levels of aerobic bacteria and lactic acid bacteria at 8°C on day 8 by 2.82 and 2.61 log CFU/g, respectively. By days 12 and 16, levels of these bacteria were equivalent to those of controls. The shrimp treated with this spice and herb combination had significantly lower (P < 0.05) lipid oxidation on days 4 and 16. None of the spice and herb extract combinations had an effect on levels of L. monocytogenes or S. aureus or changed the color or pH of the shrimp during storage. The results of this study indicate that combinations of galangal, rosemary, and lemon iron bark extracts can be used to control the growth of spoilage microflora on ready-to-eat shrimp.

Different Strains

Different strains of lactic acid bacteria isolated from bologna were inoculated into APT broth and vacuum-packed bologna sterilized by gamma radiation. Broth cultures of Leuconostoc mesenteroides reduced nitrite levels at 5 and 15 C at a greater rate than Lactobacillus plantarum and Lactobacillus viridescens. Brochothrix thermosphacta and Lactobacillus brevis reduced nitrite at rates similar to the uninoculated broth. Similar nitrite reduction rates were noted with the same organisms in the inoculated packs of bologna at 5 C. Residual nitrite losses in the bologna by action of the lactic acid bacteria was estimated to be 30%.
