In-depth exploration of the high and normal pH beef proteome: First insights emphasizing the dynamic protein changes in Longissimus thoracis muscle from pasture-finished Nellore bulls over different postmortem times.

This study aimed to evaluate for the first time the temporal dynamic changes in early postmortem proteome of normal and high ultimate pH (pHu) beef samples from the same cattle using a shotgun proteomics approach. Ten selected carcasses classified as normal (pHu < 5.8; n = 5) or high (pHu ≥ 6.

Assessment of beef sensory attributes and physicochemical characteristics: A comparative study of intermediate versus normal ultimate pH striploin cuts.

The quality of beef, defined by key attributes such as the intrinsic sensory qualities texture, flavour, and juiciness, is shaped by various intrinsic and extrinsic factors. This study conducted a detailed examination of Nellore beef, focusing on two categories based on ultimate pH (pHu) levels: intermediate (pHu ≥ 5.8) and normal (pHu < 5.

Consumer's perception and expected liking of labels of burgers with sodium reduction and addition of mushroom flavor enhancer.

This study investigated consumers' perception of labels of burgers with sodium reduction and/or addition of mushroom flavor enhancer. Six visual stimuli were created using a factorial design with sodium content (regular, sodium-reduced, and sodium-reduced plus health claim) and flavor enhancer (monosodium glutamate (MSG) and mushroom extract) as factors. Consumers answered an attitudinal questionnaire and evaluated the stimuli through expected liking and check-all-that-apply (CATA) questions.

Original burger (traditional) or burger with mushroom addition? A social representation approach to novel foods.

Currently, consumers' interest in healthy products has attracted the attention of academia and the meat industry, which has focused mainly on incorporating ingredients with healthier properties. In this context, the aim of this study was to investigate the social representation of original burgers and burgers with mushroom addition considering different sexes and body mass indexes (BMIs) of individuals. Thus, 209 Brazilians answered a word association task followed by a word classification based on their importance and valence for original burgers and burgers with the addition of mushrooms.

Relationship between volatile organic compounds, free amino acids, and sensory profile of smoked bacon.

Flavor is one of the most important characteristics of smoked bacon, strongly affecting its liking by consumers. The smoking process, lipid oxidation and proteolysis contribute to bacon quality through the generation of odors and flavor compounds. In this study, the relationships between free amino acids (FAAs), volatile organic compounds (VOCs) and sensory characteristics of smoked bacon stored for 60 days at 5 °C were investigated.

Enrichment of NaCl-reduced burger with long-chain polyunsaturated fatty acids: Effects on physicochemical, technological, nutritional, and sensory characteristics.

This study aimed to determine the effect of NaCl reduction and addition of long-chain polyunsaturated fatty acids (PUFA) on the quality traits of burgers. Fish oil was either directly incorporated or added as encapsulated by freeze-dried microparticles (complex coacervates) composed of soy protein isolate and inulin. Despite the differences in some parameters associated with NaCl reduction (e.

Modification of NaCl structure as a sodium reduction strategy in meat products: An overview.

Sodium chloride (NaCl) is an indispensable ingredient in meat products, but the consumption of high doses of sodium contained in their formulations may bring about negative health implications. The replacement of NaCl by other salts in meat products has been a technological challenge. Accordingly, this review highlights the importance of NaCl over other sodium and non‑sodium salts in the saltiness perception and proposes the use of reduced-size and shapes of NaCl to maximize saltiness perception, while using less NaCl dosages in meat products.

Agaricus bisporus mushroom as partial fat replacer improves the sensory quality maintaining the instrumental characteristics of beef burger.

The effect of Agaricus bisporus (AB) mushroom as a fat replacer in beef burgers was evaluated. Four treatments were compared: control (0% AB, 20% fat) and 3 treatments with partial fat replacement: AB 5% (5% AB, 15% fat); AB 10% (10% AB, 10% fat); AB 15% (AB 15%, 5% fat). Mushroom addition increased moisture content and yield and decreased cooking loss and diameter reduction of the burgers.

Impact of the content and size of NaCl on dynamic sensory profile and instrumental texture of beef burgers.

The objectives of this study were to determine the effect of reducing the content and size of NaCl on the instrumental texture and dynamic sensory profile, and to determine the temporal drivers of liking (TDL). The reduction of the NaCl content decreased the hardness and chewiness parameters, and affected the dynamic sensory profile of the product. The NaCl reduction (<1.

Reducing the sodium content without modifying the quality of beef burgers by adding micronized salt.

This study determined the effect of the incorporation of micronized salt on physicochemical, yield and consumer's sensory characteristics of beef burger. The micronized salt was obtained by sieving the commercial salt in a 60-mesh stainless steel sieve. The commercial (regular salt) and micronized salt presented differences in the mean size, size distribution and bulk density.
