An Exploratory Study of the Purchase and Consumption of Beef: Geographical and Cultural Differences between Spain and Brazil.

Beef consumption and production in Spain and Brazil are different with the consumption of beef in Brazil being three times higher than in Spain. In addition, there are variations in the economic value of production and in the traceability system. Therefore, the aim of this research was to understand the purchasing and consumption patterns using the customer behavior analysis technique of focus groups, which analyzed motivations for the consumption of beef, classifying their preferences by the intrinsic and extrinsic attributes at the time of purchase.

Number of consumers and days of display necessary for the assessment of meat colour acceptability.

Visual assessment is regarded as the gold standard to evaluate meat colour shelf-life, but it is costly and time consuming. To address this issue, this paper aims to evaluate the number of consumers and days of display that are necessaries in order to assess the colour shelf-life of meat, presented with different methods, all using images. Photographs of thirty-six lamb steaks were taken just after cutting (day 0) and on each of the following days until the 14th day of display under standardized conditions.

A new single nucleotide polymorphism in the calpastatin (CAST) gene associated with beef tenderness.

First we looked for putative causative mutations in the CAST and CAPN1 genes associated with meat tenderness and found a total of 31 and 7 polymorphisms, respectively, in the Parda de Montaña and Pirenaica breeds. Tenderness was not affected by mutations in CAPN1. However, three SNPs located at intron 5 (BTA7: g.
