Genomic insights of Salmonella isolated from dry fermented sausage production chains in Spain and France.

The presence of Salmonella in dry fermented sausages is source of recalls and outbreaks. The genomic diversity of 173 Salmonella isolates from the dry fermented sausage production chains (pig carcasses, pork, and sausages) from France and Spain were investigated through their core phylogenomic relationships and accessory genome profiles. Ten different serovars and thirteen sequence type profiles were identified. The most frequent serovar from sausages was the monophasic variant of S.Typhimurium (1,4,[5],12:i:-, 72%) while S. Derby was in pig carcasses (51%). Phylogenomic clusters found in S.1,4,[5],12:i:-, S. Derby, S. Rissen and S.Typhimurium serovars identified closely related isolates, with less than 10 alleles and 20 SNPs of difference, displaying Salmonella persistence along the pork production chain. Most of the S. 1,4,[5],12:i:- contained the Salmonella genomic island-4 (SGI-4), Tn21 and IncFIB plasmid. More than half of S. Derby strains contained the SGI-1 and Tn7. S.1,4,[5],12:i:- genomes carried the most multidrug resistance genes (91% of the strains), whereas extended-spectrum β-lactamase genes were found in Typhimurium and Derby serovars. Salmonella monitoring and characterization in the pork production chains, specially S. 1,4,[5],12:i:- serovar, is of special importance due to its multidrug resistance capacity and persistence in dry fermented sausages.

Filtration and antioxidant activity of commercial fermented and non-fermented sausage

This study aims to screen peptides from commercially available fermented and non-fermented sausages in the local market, examine the chemical content of the products, and determine their antioxidant activities. The chemical content of the sausages was determined using proximate analysis and the Lowry assay. The antioxidant activity was measured using the DPPH method. The data were analyzed using ANOVA. The results showed that in the proximate analysis, only the water and fat content of the three sausages differed significantly (P<0.05). The concentration of protein in the fermented sausages was significantly higher than in the non-fermented sausages (P<0.05), with the highest protein content found in the fermented Pepperoni sausage. The non-fermented beef sausage extract had a higher IC50 value (log 2.07 ppm or 117 ppm) compared to Pepperoni and Salami sausages (P<0.05). The best IC50 value in inhibiting DPPH reactivity was found in the fermented Pepperoni sausage, followed by Salami and non-fermented sausages. This indicates that fermentation can increase the chemical content and antioxidant capabilities of the fermented sausage products.

Evaluating the Potential of Korean Mudflat-Derived Penicillium nalgiovense SJ02 as a Fungal Starter for Manufacturing Fermented Sausage.

The objective of this study was to isolate, identify, and evaluate novel Korean starter cultures for use in fermented sausages. A total of 72 strains were isolated from various indigenous sources, including Nuruk, Jeotgal, and mudflats on the west coast of South Korea. Two strains were identified as Penicillium nalgiovense (SD01 and SJ02), a traditional starter used in the production of fermented sausages. A comparative analysis was performed between SD01 and SJ02 using the commercial starter culture (M600). Strain SJ02 exhibited superior lipolytic and proteolytic activities, as well as an enhanced growth rate at the optimal salinity level of 2% NaCl compared to M600. No significant differences were observed in thiobarbituric acid reactive substances values, sausage colors, and texture properties between SJ02 and M600 fermented sausages, except for adhesiveness. Profiles of mycotoxin-related genes were similar for both strains. Electronic nose analysis revealed distinct aroma profiles between SJ02 and M600 fermented sausages, with a relatively higher levels of propan-2-one and butyl butanoate in SJ02, and a higher level of ethanol and propanal in M600. In electronic tongue analysis, there was no significant differences in taste characteristics between SJ02 and M600. These results indicate that P. nalgiovense SJ02 is a potential starter culture to produce dry fermented sausages, enhancing Korean style cured meat processing industry.

Debaryomyces hansenii Strains from Traditional Chinese Dry-Cured Ham as Good Aroma Enhancers in Fermented Sausage

In some countries, yeasts are still not allowed in the production of commercially fermented sausages. Therefore, further research is needed on producing fermented meat products using different strains of yeasts. In this study, two strains of Debaryomyces hansenii (D. hansenii Y61 and Y67) were inoculated in fermented sausages to study their effects as starter cultures. The inoculation of D. hansenii strains affected ripening by decreasing the pH and aw. The sausages inoculated with Y61 and Y67 exhibited decreases in lipid oxidation of 40.70% and 36.04%, respectively, and Enterobacteriaceae counts of 50% and 100%, respectively. The inoculating yeasts Y61 and Y67 increased the lightness (L*) and redness (a*) of fermented sausages. The D. hansenii-inoculated sausages had higher levels of free amino acids and fatty acids, which improved the digestibility, sensory value, and safety of these sausages. Moreover, the total amount of ester compounds increased by 87.14% and 83.31% in the Y61- and Y67-inoculated groups, respectively, which contributed to the aroma. Better sensory attributes were also found in the sausages inoculated with Y61 and Y67 D. hansenii. Native D. hansenii Y61 and Y67 are, therefore, good starter cultures for fermented sausage production. Together, the results provide data supporting future research and the use of yeast-fermented sausages.

Technological traits and mitigation activity of autochthonous lactic acid bacteria from mediterranean fermented meat-products

The production of safe and standardized fermented sausages with typical characteristics linked to traditional origin is highly desirable. The use of autochthonous starter cultures that provide peculiar flavor, texture and color to the fermented products, while maintaining the meat-product safe can be a feasible strategy for producers. In this study, 45 strains of Latilactobacillus sakei and 1 Latilactobacillus curvatus isolated from natural Mediterranean fermented sausages, were screened as potential protective cultures for their use in the fermented sausage industry. Technological properties, inhibitory activity towards Escherichia coli and Listeria innocua and the presence of genes coding for bacteriocins, were investigated. All tested strains showed an antagonistic effect by growing, while inhibiting the growth of target harmful microorganisms, in a strain-specific manner. At least one bacteriocin encoding genes was present in 25 strains, mainly sakacin X and sakacin P. The technological performances of the strains highlighted a great variability in the behavior, confirming the phenotypic diversity already reported for LAB species highly adapted to meat environment. Results highlight the potentiality of these strains to be used as protective starters in fermented meat products to improve food quality and microbiological safety, as well as giving peculiar characteristics to the final product.

Effects Of Sodium Nitrite, Potassium Sorbate And α-Tocopherol On Residual Nitrite, Formations Of Biogenic Amines And N-Nitrosamines In Turkish Dry Fermented Sausage (Sucuk)

The effects of sodium nitrite, α-tocopherol and potassium sorbate on ion contents, biogenic amine (BA) and N-nitrosamine (NA) formations of Turkish type fermented sausage after storage were investigated based on Response Surface Methodology (RSM). In addition, relationships between ions, BAs and NAs were evaluated. Nitrite (NO2-) and ammonium (NH4+) ion amounts in all sausage samples were below limit of detection. The effects of factors are partially effective on the formation of nitrate (NO3-), BAs and NAs. There was a positive correlation between NO3- and N-nitrosodiethylamine (NDEA), and no correlation between other ions and BAs. The accumulations of tryptamine (TRP), tyramine (TyR) and spermidine (SPD) increased formations of NDEA, N-nitrosodi-n-propylamine (NDPA) and N-nitrosomorpholine (NMOR), respectively. It is concluded co-addition of sodium nitrite and potassium sorbate and/or α-tocopherol in fermented sausage production can significantly reduce amount of residual nitrite, thus inhibiting NAs.

Influence of propionic acid microorganisms on the quality indicators of the produced sausage

The article considered the effect of probiotic bacteria on the quality of meat for semi-smoked sausages. The biochemical activity of propionic acid bacteria was studied at the stage of the production process of semi-smoked sausages after the treatment of raw materials with starter microorganisms. We also studied the effect of salt, and sodium nitrite on the development of propionic acid bacteria in raw beef. The results of the technology of production of semi-smoked sausages treated with propionic acid bacteria in the amount of 0.1%, and the quality characteristics of the finished sausage products are presented. On the basis of experimental studies optimal technological parameters of salting and precipitation in the production of fermented semi-smoked sausages were selected. The use of liquid propionic acid bacteria (2 strains of propionic acid bacteria Propionibacterium shermani) in the amount of 0.1% will give a decrease in the production time of half-smoked sausages by two times. As a result of the research it was proved that the introduction of 2 different strains of propionic acid bacteria concentrate into raw meat accelerates biochemical changes in the process of salting and provides functional and technological properties. Also, the results of the study showed that propionic acid bacteria used in the technology of semi-smoked sausages are resistant to the amount of food salts and sodium nitrite used. As a result of research, a better way of using liquid propionate microorganism in the production of semi-smoked fermented sausages was adopted.

Improving the aroma profile of inoculated fermented sausages by constructing a synthetic core microbial community.

Commercial starter cultures play a critical role in the industrial production of fermented sausages. However, commercial starter cultures could not reproduce the metabolic actions of diverse microorganisms and the aroma profile of the traditional spontaneously fermented sausages. Identifying the core microbial community in spontaneously fermented sausages will facilitate the construction of a synthetic microbial community for reproducing metabolic actions and flavor compounds in spontaneously fermented sausages. This study aimed to reveal the core microbial community of spontaneously fermented sausages based on their relative abundance, flavor-producing ability, and co-occurrence performance. We identified five promising genera to construct the synthetic core microbial community, these were Lactobacillus, Staphylococcus, Macrococcus, Streptococcus, and Pediococcus. Sausages inoculated with a synthetic core microbial community presented higher quality of aroma profile than the fermented sausages inoculated with a commercial starter culture. Some important volatile flavor compounds of spontaneously fermented sausage, such as (-)-β-pinene, β-caryophyllene, 3-methyl-1-butanol, α-terpineol, ethyl 2-methylpropanoate, and ethyl 3-methylbutanoate which are associated with floral, fruity, sweet, and fresh aromas, were also detected in fermented sausage inoculated with synthetic microbial community. This indicated that the synthetic core microbial community efficiently reproduced flavor metabolism. Overall, this study provides a practical strategy to design a synthetic microbial community applicable to different scientific fields.

Selection of Debaryomyces hansenii isolates to improve quality of dry fermented sausage

ABSTRACT The objective of this experiment was to select D. hansenii isolates that are stable in dry fermented sausage (DFS) production and can positively affect the quality. D. hansenii isolates were examined for production of biogenic amines, β-glucuronidase, β-glucosidase, proteolytic, and lipolytic enzymatic activities. The acid and salt tolerance of D. hansenii isolates were also examined. DFS inoculated with selected D. hansenii isolates were analyzed for microorganisms, weight loss, Aw, and pH. DFS was also subjected to analyses of color, texture profile, reducing sugar, volatile basic nitrogen (VBN), lipid oxidation, and free fatty acid. Twenty-two D. hansenii isolates were isolated. None of these D. hansenii isolates produced biogenic amines, and all strains were negative for β-glucuronidase and β-glucosidase activities. After examining these strains for proteolysis, lipolysis, and salt and acid tolerance, D. hansenii isolates SMFM2021-C14, SMFM2021-S8, and SMFM2021-SL3 were selected to be used in DFS. During the processing of DFS, the groups treated with D. hansenii isolate SMFM2021-S8 or SMFM2021-SL3 showed lower (p < .05) hardness values of DFS. The sample treated with D. hansenii SMFM2021-S8 showed lower (p < .05) VBN and lipid oxidation contents than the others. The ratio of ω-6/ω-3 was lower (p < .05) in D. hansenii SMFM2021-SL3 treated group than in the other treatments. These results indicate that D. hansenii isolates SMFM2021-S8 and SMFM2021-SL3 might be useful in producing DFS to improve its quality.

Application of beekeeping products in the technology of raw smoked sausages

The safety of fermented sausage products is due to the elimination of a number of risks of biological origin, mainly of a microbiological nature. One of the most promising directions for the development of barrier technologies is the use of starter cultures and the biologically active substances produced by them in the production of fermented meat products. The research aims to study the influence of starter cultures and honey on a complex of physico-chemical, structuralmechanical, organoleptic indicators and nutritional value of raw smoked sausages. The article presents changes in the physical and chemical parameters of raw smoked sausages when using starter cultures in combination with different types of honey. When performing the work, 4 types of honey were used: from sunflower, phacelia, honeydew honey and from medicinal herbs. At the first stage of research, the proportion of honey application and the type of starter crops were selected. The next stage of the study was to determine the impact of the starter cultures included in the product BIOSTART PLUS 50 (lactic acid bacteria Lactobacillus Sake and yeasts Debaryomyces Hansenii) and honey on moisture loss during fermentation of raw smoked sausages, physicochemical parameters of finished products. Determination of moisture content in samples was carried out by drying in a drying cabinet at a temperature of 103±2°C. Conducted studies prove that the use of the product BIOSTART PLUS 50 (lactic acid bacteria Lactobacillus Sakei and yeasts Debaryomyces Hansenii) and honey allows shortening the ripening and drying technological process. A comparative analysis of manufactured raw-smoked sausages in terms of nutritional value makes it possible to state that manufactured raw-smoked sausages with the addition of honey meet the requirements of the standard. The results of the set of studies carried out in this work showed that the use of a composition of lactic acid bacteria and yeast with the use of honey as a source of carbohydrates will allow intensifying the technological process and improve the quality of finished products

Effects of cranberry powder on the diversity of microbial communities and quality characteristics of fermented sausage.

Fermented sausage is popular with many consumers because of its distinctive flavor, but the safety of it has attracted widespread attention. At present, nitrite is widely used in fermented meat products because of its ideal color and bacteriostatic effect, but nitrite can be transformed into nitrosamines, which cause strong carcinogenic effects. Therefore, it is urgent to actively explore safe and efficient nitrite substitutes. In this study, cranberry powder was selected as a natural substitute for nitrite during the production of fermented sausage due to its unique antioxidant and bacteriostatic properties. The results showed that adding an appropriate amount of cranberry powder (5 g/kg) promoted a better color of the fermented sausage and promoted the accumulation of aromatic compounds. Furthermore, Pediococcus and Staphylococcus became the dominant species, accounting for more than 90% in all samples. According to the Pearson correlation analysis, Staphylococcus and Pediococcus had positive effects on the quality characteristics of fermented sausage products. This study provided the latest information on the application of cranberry powder as a natural substitute for nitrite in the process of manufacturing fermented sausage, and it also introduced an advanced solution to improve the quality characteristics and safety of fermented sausage products during processing.

Effects of anaerobic and respiratory adaptation of Lacticaseibacillus casei N87 on fermented sausages production

Lacticaseibacillus casei N87 was used as starter culture for the production of fermented sausages. The strain was cultivated in anaerobic (A) and respiratory (growth in presence of oxygen and supplementation with haeme and menaquinone in the growth medium; R) conditions. Control without the starter culture inoculation and with the addition of 150 mg/kg of nitrate was also included. The effect on physico-chemical parameters (pH, Aw, weight loss, and color), microbial population, volatilome, proteolysis as well as the survival of the strain was evaluated during 90 days of ripening. Q-PCR and DGGE-PCR analyses demonstrated the ability of the strain used in this study to adapt to this environment and carry out the sausage's fermentation process. The inoculation of the strain did not have any effect on the Aw values, which decreased similarly in the different samples whereas the pH was lower in A samples (5.2) and the weight loss in R samples (2.5% less than the others). The color parameters of the samples inoculated with the starter cultures were comparable to those of the control added with nitrate. The concentration of aldehydes that usually are identified as marker of oxidation processes was similar in the samples inoculated with the starter cultures adapted under respiratory conditions and in the control. On the contrary, a higher level was detected in the samples inoculated with the starter cultivated under anaerobic conditions. The proteolysis that occurred during the ripening indicates the differentiation of the A samples from the others. Nonetheless, the volatile profiles of the inoculated fermented sausages were similar. The study demonstrated that aerobic adaptation of Lcb. casei N87 starter culture gave similar color parameters and amounts of aldehydes in sausages fermentations without nitrate compared to conventional fermentations with nitrate.

Angiotensin‐converting enzyme (ACE) inhibitory peptides from fermented sausages inoculated with Lactobacillus plantarum CD101 and Staphylococcus simulans NJ201

AbstractNatural ACE inhibitory peptides derived from food are considered to be an effective supplement for lowering blood pressure. This study investigated the effects of Lactobacillus plantarum CD101 and Staphylococcus simulans NJ201 on proteolysis and the sequence composition of ACE inhibitory peptides in fermented sausages. The ACE inhibitory activity of the inoculated group reached the maximum values on day 35 during the production of fermented sausages. A more positive effect in the hydrolysis of the sarcoplasmic and myofibrillar protein was observed in the inoculated group through sodium dodecyl sulphate–polyacrylamide gel electrophoresis (SDS‐PAGE). The free amino acid content of the inoculated group was 865.21 ± 12.55 mg/100 g, which was significantly higher (P &lt; 0.05) than that of the control group. The molecular weight distribution showed a significant increase (P &lt; 0.05) in peptides with a molecular weight less than 1 kDa in the inoculated group. A total of thirty‐four peptides with high hydrophobicity were identified by liquid chromatograph‐mass spectrometer/mass spectrometer (LC–MS/MS). Furthermore, the peptides were isolated and purified using gel filtration chromatography (GFC) and reversed‐phased high‐performance liquid chromatography (RP‐HPLC). Eleven novel peptides were identified by Nano‐LC‐ESI‐MS/MS, in which VALSLSRP with X‐Pro structure exhibited the highest ACE inhibition rate (75.36 ± 2.45%). These results indicated that mixed starters are conducive to protein degradation and the formation of peptides with high ACE inhibitory activity, especially peptides less than 1 kDa, and could be used as a functional material for antihypertensive drugs.

Determination of Hydroxyproline Amount of Fermented Sausages by HPLC and Revealing the Relationship between Quality Parameters

Introduction: Fermented sausage is the food that has the largest share in consumption among other fermented meat products in Turkey. Although it is difficult to achieve the production standard in fermented sausage production, it is necessary not to exceed the legally determined reference values for quality production. Determining and controlling quality parameters in macro and micronutrients in the composition of fermented sausage, compliance with production standards, storage conditions, etc. has become a necessity.&#x0D; Purpose: It is aimed to determine whether there is adulteration and imitation in the production of fermented sausages, to determine the structural defects during and after production, to evaluate their compliance with legal regulations and their nutritional quality.&#x0D; Study Design: The study was mainly designed on the determination of hydroxyproline amounts with a High-Performance Liquid Chromatography device.&#x0D; Study Place and Duration: The samples used in the study were collected within the borders of Burdur province. All experimental studies were carried out at Burdur Mehmet Akif Ersoy University (MAKU), Veterinary Faculty, Department of Food Hygiene and Technology; MAKU Scientific and Technology Application and Research Center and Uşak University, Engineering Faculty, Department of Food Engineering Laboratories. The study covers a period of 3 months between October 2020 and December 2020.&#x0D; Methodology: A total of 30 fermented sausage samples, which are offered for sale by butchers and markets, were collected, brought to the laboratory by cold chain and subjected to analysis. After the samples were analyzed in terms of hydroxyproline, physicochemical and textural aspects, they were evaluated statistically.&#x0D; Results: The pH values of the examined fermented sausages were 4.82-5.93, fat ratios were 12.50-38.50%, protein amounts were 12.24-24.49%, total ash values were 2.37-4.58%, salt values were determined as 1.97-4.05%, humidity values as 20.22-50.36%, water activity (aw) values as 0.80-0.97, hydroxyproline amounts as 2.01-14.85 g/kg.

Incorporation of Selected Strains of Pediococcus spp. on Quality Characteristics of Dry Fermented Sausage during Fermentation and Ripening.

This research investigated the physio-chemical and microbial quality characteristics of dry fermented sausage from selected Pediococcus strains: P. acidiliactici (PE1) and P. pentosaceus (PE2) as compared to commercial starter culture (COS) during fermentation and ripening. Treatments showed no substantial variation (p<0.05) in water activity (aw) values across the study period. PE1 and PE2 treatments exhibited similar (p>0.05) pH values and presented remarkable (p<0.05) lower volatile basic nitrogen (VBN) and thiobarbituric acid reactive (TBARS) content than COS treatment throughout the ripening period. However, the pH values in COS batch were considerably lower than others. PE1 samples presented a significant highest (p<0.05) counts both in lactic acid bacteria (LAB) and total plate count (TPC) than COS and PE2 treatments at 7 days fermentation, and it resulted in a similar and higher TPC count as COS after the ripening period. After the ripening process, treatments are ordered based on LAB counts as follows: COS>PE1>PE2. All batches presented similar redness and yellowness attributes since the 7 days of fermentation and in lightness across the study period. Treatments were similar (p>0.05) in springiness and chewiness traits across the study period and in hardness characteristics in the ripened products. Cohesiveness was higher in PE1 and COS batches. No variation (p>0.05) in aroma and sourness sensory attributes of treatments. The color attribute was highest (p<0.05) in PE1 and PE2 treatments and PE1 had the highest overall acceptability. The overall outstanding merit exhibited by PE1 can be utilized in the commercial production of high-quality dry fermented sausage.

Influence of polyphenols on sensory properties of fermented sausages

In the current research, the use of polyphenols in the production of fermented sausages as a natural preservative and their influence on the sensory characteristics of these products were investigated. Polyphenols could have antimicrobial and antioxidant roles in meat products, but also a range of positive biological effects on consumers. The results of the research showed that the addition of polyphenols did not significantly affect the sensory properties (colour, cross-section appearance, consistency, odour and flavour) of the three groups of sausages (control fermented sausage and two sausage variants, one with nitrite and one without nitrite), and that sausages were highly rated during most of the storage period. In addition, all tested sausages were evaluated as acceptable until the end of the entire storage period, i.e., throughout the 280-day period after sausage production.

Chemical quality parameters (water, protein, fat, NaCl ash and nitrites) in fermented sausage with the addition of Yersinia enterocolitica

The connection between diet and health was known to the oldest civilizations. Meat processing has influenced the increase of meat consumption, protein utilization and its energy value. Fermented sausages which are prepared in a safe way are rich in animal proteins and are an important part of the diet. Meat and adipose tissue are the basic ingredients in the production of fermented sausages, along with spices and salts, and other additives depending on the specifics of the product. Ripening is a process that separates raw sausages from all other types of sausages, and the quality of raw materials and their treatment directly affects the quality of the finished product, because the process of fermented sausage production is dominated by biological and biochemical processes. Different types of foods can cause food-borne illnesses, one of which is zoonotic yersiniosis caused by Yersinia enterocolitica. Due to the importance of Yersinia in meat, the European Food Safety Authority (EFSA) recommended that in addition to controlling the presence of Salmonella, it is mandatory to examine pork carcasses for the presence of Y. enterocolitica.

Prevalence, serovar, and antimicrobial resistance of Salmonella isolated from meat and minced meat used for production smoked sausage

The objective of this study was to research the prevalence, serovars, and antimicrobial resistance profiles of Salmonella isolated from meat and minced meat used for the production of fermented sausage. A total of 116 samples were tested, and among them, 20 (17.2%) were positive. Salmonella was detected in 3 (10.3%) beef samples, 5 (19.2%) pork samples, and 6 (20.7%) poultry samples. In minced meat, the Salmonella prevalence was 18.8%. Salmonella enterica serovar Agama (5.2%) was the most commonly identified serovar, followed by S. Enteritidis (4.3%), S. Typhimurium (3.4%), S. Infantis (2.6%), and S. Lindenburg (1.7%). Most of the serovars identified in the present study are recognized as frequent causes of human salmonellosis. Thus, the presence of these serovars means foods with these meats are a likely source of human infections. We found the Salmonella isolates exhibited high rates of resistance to antimicrobials tetracycline, ampicillin, streptomycin, and ciprofloxacin. The highest level of resistance was to tetracycline (75%), followed by resistance to ampicillin (50%), streptomycin (30%), ciprofloxacin (20%), gentamicin (20%), and neomycin (10%). The high-level resistance observed for some of the serovars calls for concern. Salmonella with multidrug resistance in meat used to produce fermented sausages is considered a high additional risk for human health.
