Floor drainsof the hotbox area and storage cooler of the same plant were sampled forenvironmental microorganisms. Biofilm formation on stainless steel (SS) surfaceby the isolated S. enterica strains and the microorganisms recoveredfrom the drains were assessed. Pathogen survival and community compositionsafter sanitization (quaternary ammonium compound, QAC) were examined. Alone theCerro strain formed greater (p<0.05) biofilm mass (5.4 Log10CFU/SS chip) than the Montevideo or Typhimurium strains (4.6 and 4.8 Log10CFU/SS chip, respectively). The Typhimurium strain was the most QAC tolerant(0.3 log reduction) while the Cerro and Montevideo strains exhibited similar sensitivities(1.6 log and 1.1 log reduction, respectively). The environmental microorganismsfrom the drain samples all developed biofilms ranging from 5.7 to 6.0 Log10CFU/SS chip. All S. enterica strains were efficiently integrated intothe drain biofilms where the Montevideo and Typhimurium strains ranged from 3.8to 4.7 Log10 CFU/chip, and the Cerro strain at 4.0 to 5.8 Log10CFU/chip. Enhanced QAC tolerance was only exhibited by the Montevideo strainwhen integrated into the drain biofilms. Metagenomic analysis of the drainbiofilms showed the most abundant genus was Pseudomonas (57.7%), followedby Brochothrix (28.6%), Serratia (7.2%), Lactococcus (4.2%),and Carnobacterium (1.1%), with all varying significantly among thedifferent biofilm samples and their response to QAC treatment. Thus, various factorsunderlie the survival advantages of the S. enterica strains allowingthem to tolerate stress, outcompete and coexist with environmental companionbacteria for protection, which might lead to pathogen prevalence and recurrentproduct contamination.    ","PeriodicalId":18316,"journal":{"name":"Meat and Muscle Biology","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84506906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increased solvent access to the heme pocket has been proposed to cause oxidation of the heme iron and decrease heme affinity, although empirical results are lacking.  This review introduces plasma induced modification of biomolecules (PLIMB) as an approach to modify amino acids of Mb and Hb and thereby assess solvent access to the heme pocket. After PLIMB, liquid chromatography tandem mass spectrometry (LC-MS/MS) peptide analysis and a user-friendly, software platform is utilized to quantify modified amino acid side chains of the heme proteins. Our current findings indicate that PLIMBàLC-MSMS provides a platform to measure solvent access to portions of the heme pocket environment. Evaluation of PLIMB at additional conditions (e.g. different pH values) is underway to better delineate the role of solvent access to the heme pocket relative to the ‘outer-sphere’ mechanism of heme protein oxidation and the ability of hydrogen bonding to stabilize heme within metHbs. Some aspects of heme protein-mediated lipid oxidation that occur at low O2 partial pressures are discussed in relation to solvent access to the heme pocket. Other approaches to study mechanisms of discoloration and lipid oxidation related to Mb/Hb oxidation and heme loss from metHb are also discussed.","PeriodicalId":18316,"journal":{"name":"Meat and Muscle Biology","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88179267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In experiment 1, L*, a*,and b* values and various reflectance traits of the Farnsworth Munsell85-Hue tiles were measured. Incremental changes of the tiles were used topredict changes in a* values and other color variables that can be seenby a trained visual panel. Regression analysis suggests that trained paneliststhat pass the Farnsworth Munsell Hue test can discriminate a change of 0.95 in a*,0.9 in b*, and 2.54 in hue angle values when Illuminant A is used. Inexperiment 2, ground beef was assigned randomly to 1 of 36 combinations of 3 storagetemperatures, 4 storage times and 3 display temperatures to create a variety ofsurface colors. A 10% change in ground beef metmyoglobin content correspondedto 3.2 units of a* (R2 = 0.95). Of all the instrumentalmeasurements, a* (r = -0.97) and chroma (r = -0.97) best represented thered color intensity that panelists saw on the surface of ground beef. Significantsurface discoloration occurred at 37.1% metmyoglobin and an a* value of25.4 (with Illuminant A). Using a five-point visual lean color scale, thechange required in a* value for a unit change visual color score was 4.6.In conclusion, a* and chroma are highly related with visual colorscores and changes in metmyoglobin, and a change in a* of 0.95 can beobserved by visual panelists that have passed the Farnsworth Munsell test.  ","PeriodicalId":18316,"journal":{"name":"Meat and Muscle Biology","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73938567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study makes several unique contributions to literature, but the specific hypotheses are growing the introduction of a brisket in the quick service restaurant chain increased brisket prices. Also, we hypothesize that consumer interest is also increasing brisket prices. only Choice briskets were found to have a significant own-price flexibility (P<0.01) and cross-price flexibility  (P<0.01). That means when the supply of Choice brisket changes, the price of Choice and other graded briskets changed, which is expected since Choice briskets are the largest portion in the supply chain. Cross-quantity flexibilities showed substitutes across brisket quality grades and pork shoulders (P<0.05). The Google Trends variable revealed that as interest, defined as more internet searches, increased, the brisket prices increased over time (P<0.01).

However, fresh meat immediately postmortem andmeat undergoing processing become susceptible to oxidation due to physicaldisruption and the influx of molecular oxygen. Upon the activation byendogenous prooxidants, oxygen species are rapidly produced, and bothmyofibrillar and sarcoplasmic proteins become their primary targets. Direct ROSattack of amino acid sidechains and peptide backbone leads to proteinconformational changes, conversion to carbonyl and thiol derivatives, andsubsequent aggregation and polymerization. Interestingly, mild radical andnonradical oxidation enables orderly protein physicochemical changes, which explainswhy gels formed by ROS-modified myofibrillar protein has improved rheologicalproperties and binding potential in comminuted meat and meat emulsions. Theincorporation of phenolic and other multi-functional compounds promotes gelnetwork formation, fat emulsification, and water immobilization; however,extensive protein modification induced by high levels of ROS impairs proteinfunctionality. Now recognized to be a natural occurrence, once-neglectedprotein oxidation has drawn much interest and is being intensively studiedwithin the international community of meat science. This review describes thehistory and evolution of muscle protein oxidation, the mechanism andfunctionality impact hereof, and innovative oxidant/antioxidant strategies tocontrol and manipulate oxidation in the context of meat processing, storage,and quality. It is hoped that the review will stimulate in-depth discussion of scientificas well as industrial relevance and importance of protein oxidation and inspirerobust international collaboration in addressing this global challenge. ","PeriodicalId":18316,"journal":{"name":"Meat and Muscle Biology","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79173744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
