Additionally, Iberian hams differing in genetic background namely, BLACK (100 % Iberian) and RED (50 % Iberian) were found to differ in 142 discriminating metabolites. Sixty-six distinctive metabolites were found in RED hams, produced from pigs fed on natural resources, while seventy discriminating metabolites were identified in GREEN hams, produced from pigs fed on concentrate.

RFs were also developed as they are particularly robust. We applied both methods on 19 compounds/variables measured on different tissues (perirenal fat (PF), dorsal fat (DF) and <em>longissimus thoracis et lumborum</em> (LTL) muscle) in an experiment using <em>Romane</em> male lambs pasture-finished on lucerne for four durations pre-slaughter (<em>n</em> = 34–36 lambs per group). Several DTs/RFs were constructed including measurements that are relatively easy to carry out in the abattoir/point of sale, or measurements requiring laboratory analyses. The DTs/RFs distinguished carcasses of lambs pasture-finished from stall-fed lambs with an accuracy of up to 95.1–95.7 %, and showed that PF skatole and PF carotenoid pigment content (out of 19 variables) played a prominent role in classification. The DT/RF designed for use at the point of sale, which was based on DF spectrocolorimetric characteristics and LTL muscle colour coordinates, achieved 84.3–85.4 % accuracy. This is the first research to use DTs for meat authentication, and threshold values for classification decisions will probably need to be validated further on larger databases. These findings nevertheless raise prospects for broad application of decision trees for authentication.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"227 ","pages":"Article 109852"},"PeriodicalIF":7.1,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ochratoxin A (OTA) is the most prevalent mycotoxin in dry-cured hams and fermented sausages. Apart from collecting information on the main toxigenic moulds in dry-cured meat products, the objective of this review is to compile data about the mycotoxin prevalence and the tools for their mitigation. Although no very extensive studies have been performed on the mycotoxin occurrence in such products, much research has been conducted over the last 15 years, particularly in the European Mediterranean countries. Large differences in OTA incidence and amount have been reported, which can be due to differences in the processing followed, the climatic conditions of the producing region, the mould population present or the used detection method. Nevertheless, most of the mean and maximum OTA values observed in dry-cured meat products are above the maximum level of 1 μg/kg recommended officially for pork products in Italy. Aflatoxin B<sub>1</sub>, cyclopiazonic acid, sterigmatocystin and citrinin are only occasionally reported from dry-cured meat products. To control mycotoxin contamination, manufacturers have several strategies available, with the biopreservation ones being the most appropriate, since the modification of environmental parameters is not feasible, especially in products with long ripening. Native microorganisms alone or in combination with plant extracts are sustainable biopreservatives with a special interest in dry-cured meat products to mitigate the mycotoxin contamination. All these strategies are extensively described in this review, with special attention paid to OTA.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"227 ","pages":"Article 109850"},"PeriodicalIF":7.1,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reducing NaCl in fresh meat products promotes the growth of psychrotrophic spoilage bacteria, such as <em>Pseudomonas</em> sp., which thrive at low temperatures, and mesophilic pathogens like <em>Escherichia coli</em> and <em>Staphylococcus aureus</em>, particularly under inadequate storage conditions. In cured and fermented meats, such as salami, lowering NaCl levels disrupts the balance of salt-tolerant microorganisms, notably lactic acid bacteria (LAB) and coagulase-negative staphylococci, potentially leading to increased spoilage and pathogen proliferation. In smoked meats, the combination of reduced NaCl and altered microbial ecology, including a shift toward LAB dominance, may weaken the inhibitory effects on spore-forming bacteria like <em>Clostridium botulinum</em>. Additionally, using metagenomics, we explore the shifts in microbial communities observed in studies involving meat, revealing critical insights into the composition and diversity of bacteria in meat products, as well as the gaps in research on the impact of NaCl reduction and/or substitution on the microbiota. This review provides a comprehensive understanding of these microbial shifts, highlighting the distinct responses of psychrotrophic, mesophilic, and LAB groups to NaCl modification and the need to understand the effects of these alternatives on the meat product microbiome, as well as the neglected microorganisms that can affect the quality and safety of these products.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"226 ","pages":"Article 109848"},"PeriodicalIF":7.1,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143943485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dietary treatment influenced final body weight, average daily gain and dry matter intake which were higher (<em>P</em> < 0.05) in the GS group than in the control group. The addition of 10 % grape seed in rabbit diet increased the accumulation of intramuscular fat (<em>P</em> < 0.05), the levels of C18:1 <em>cis-9</em> (<em>P</em> < 0.01) and of the total monounsaturated fatty acids (<em>P</em> < 0.01), and tended to increase (<em>P</em> = 0.061) the sum of <em>n-6</em> PUFA in meat, whereas reduced the sum of <em>n-3</em> PUFA (<em>P</em> < 0.05), the levels of C22:5 <em>n-3</em> (<em>P</em> < 0.05) and C22:6 <em>n-3</em> (<em>P</em> < 0.05), leading to an increase (<em>P</em> < 0.01) in the <em>n-6</em> to <em>n-3</em> ratio in GS group than in control group. Grape seed supplementation reduced TBARS values (<em>P</em> < 0.01) and protected meat from lipid oxidation over time (<em>P</em> < 0.01), demonstrating that supplementation of 10 % grape seeds in the rabbit diet could improve shelf-life in meat.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"226 ","pages":"Article 109843"},"PeriodicalIF":7.1,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143906196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
