Abstract:
... Forty-eight bovine longissimus thoracis (LT) muscles, twelve from each Canada quality grade (Canada A, AA, AAA, and Prime) were used to test the hypotheses that intramuscular total collagen and collagen solubility decreased with increased quality grade and intramuscular fat, and that alkali isolation of intramuscular connective tissue (IMCT) does not reduce Ehrlich Chromogen (EC) or Pyridinoline ( ...

Abstract:
... Supercooling can preserve beef without freezing damage, whereas maintaining the supercooled state is difficult. An innovative method of static magnetic field extended supercooling (SM-ES) was proposed to maintain the non-frozen state of beef. Effect of SM-ES (−4 °C + SMF) compared with refrigerated (4 °C), slow-frozen (−4 °C) and frozen (−18 °C) treatment on beef quality was investigated. Results ...

Abstract:
... The study was undertaken to investigate the effect of muscle, thermal treatment, and ageing on the beef quality. The longissimus lumborum (LL) and semimembranosus (SM) muscles were taken from Holstein–Friesian young bull carcasses then subjected to steam-cooking and sous-vide after 9 and 14-d wet ageing. It was shown that characteristics of cooked beef were the most significantly affected by therm ...

Abstract:
... This study evaluated a range of diffuse reflectance spectroscopic (Vis-NIR spectrophotometers) and imaging (Hyperspectral imaging cameras) instruments for predicting pH, IMF and shear force values of beef in a meat processing pilot plant. A total of 364 beef striploin samples were evaluated and prediction models were developed using PLSR. Models for pH and IMF (except Vis snapshot camera) showed g ...

Abstract:
... The European Union promotes high-quality food products and protects agricultural traditions. With that vision, Regulation (EU) 1151/2012 defines quality schemes such as protected designations of origin, protected geographical indications and optional quality terms that link quality and tradition to legal labels. These quality schemes are completed by national initiatives. Label Rouge is an officia ...

Abstract:
... The SMAD1 and SMAD5 genes belong to mothers against decapentaplegic proteins family, which participate in the BMP pathway to control skeletal myogenesis and growth. In the present study, we analyzed the associations between polymorphisms of SMAD1 and SMAD5 genes promoter and important economical traits in Qinchuan cattle. Four SNPs in the SMAD1 gene promoter and three SNPs in the SMAD5 promoter we ...
... Context Their growth and feed efficiency advantages make bull beef production systems attractive alternatives for producers of beef from steers. Finishing bulls from pasture is less costly and would allow bull beef to be marketed as ‘grass-fed’. However, such carcasses may not meet the minimum fatness classification of 6.0 (on a 15-point scale) required for some beef markets. This is ...

Abstract:
... The role of cooking on pre- and post-consumption quality expectations and its impact on satisfaction during the eating experience is under-researched. To address this gap, a ‘task and talk’ focus group study involving participants preparing and eating a beef steak as part of a meal was designed to explore the role of cooking on consumers' evaluation of beef quality. The results from six focus grou ...

Muscle fiber (MF) characteristics of longissimus thoracis (LT) muscles from heifer (n = 11) and steer (n = 12) carcasses graded Canada AA (AA, normal, n = 4 per sex) or dark-cutting (Canada B4) were examined and related to beef quality. Atypical (AB4, pH < 5.9, n = 4 per sex) and typical (TB4, pH > 5.9, n = 3 and 4 for heifers and steers, respectively) dark-cutting carcasses were represented. Musc ...

Abstract:
... Beef quality assurance initiatives have been developed to assure consumers of the quality and safety of supplied beef, as well as the environmental‐orientation of farm production practices. However, the potential economic benefits of quality schemes to European beef cattle farmers have been overlooked. This paper uses farm‐level data to identify the drivers of Irish farmers’ participation in Bord ...

Abstract:
... The effect of meat marinating with aqueous extract of Ilex meserveae dried leaves on dry-aged beef quality was investigated. Shear force, TBARS value, color parameters, fatty acid profile, and sensory properties were evaluated in beef cuts dry-aged for 21 days. The use of Ilex meserveae dried leaves as marinade at 0.5, 1.0, and 2.0% w/v did not affect the shear force and color parameters of dry-ag ...

... Following a century of major discoveries on the mechanisms determining meat colour and tenderness using traditional scientific methods, further research into complex and interactive factors contributing to variations in meat quality is increasingly being based on data-driven “omics” approaches such as proteomics. Using two recent meta-analyses of proteomics studies on beef colour and tenderness, t ...

Price, the designation of origin/brands/certification, appearance/meat colour, presentation, and visible fat are the most valorised factors used by consumers to predict quality. Flavour, tenderness, and juiciness are the most valorised beef q ...

Abstract:
... The yak is an important source for the people living and ecological environment in the Qinghai–Tibet Plateau. In every winter, many domestic yaks will lose bodyweight or dead under cold and food scarcity. Moving the plateau yaks to farm in the plain is a useful approach to reduce their environmental stress and gain more production. In this study, we measured growth, slaughter and beef quality trai ...

This study investigated the effects of refrigerated storage (RF), superchilled storage (SC), RF with natural extracts (namely, 0.3% polylysine, 0.75% Portulaca oleracea extract, and 0.03% luteolin; RF + PS) and SC with the natural extracts (SC + PS) on beef preservation quality during 24 days. Results showed that as the storage time increased, the rates at which pH, shear force, pressing loss, coo ...
... Understanding the priorities of beef consumers is important for planning strategies to attract and maintain each customer. Using self-administered interviews with Spanish and Brazilian adults who regularly consume beef, we analyzed their purchasing behaviors in relation to their perceptions and priorities regarding beef quality that guide their choices. The current study identifies the influences ...

This study compared the meat quality, histochemical traits, palatability, and expression levels of apoptotic (cytochrome c and caspases) and anti-apoptotic (small heat shock proteins) factors at 45 min and 24 h post-mortem of Hanwoo Longissimus thoracis muscles in groups categorized by Warner-Bratzler shear force (WBS) values to investigate the association between beef tenderness variation and apo ...
... The effects of ultrasound (0, 300 and 600 W for 20 min at the frequency of 20 kHz) followed by postmortem aging (0, 4 and 8 d aging time) on beef quality were evaluated. Ultrasound treatment, aging time and their interaction all significantly affected the pH and tenderness of beef (p < 0.05). Furthermore, ultrasound improved the cathepsin B + L activities and the solubility of collagen compared wi ...
