Physicochemical characteristics that influence the meat pork quality in supermarkets in the central highlands of Mexico

Twenty-two supermarkets in the Central Highlands of Mexico were sampled in order to classify them and to compare their pork meat quality based on its physicochemical characteristics. The supermarkets were classified in three types in accordance with socioeconomic status of buyers as low, medium, and high. Methods: Samples were obtained from the Longissimus dorsi muscle from 10th to 12th ribs. Results: Objective color was L* 46.97, a* 6.22 and b* 5.1. Subjective color indicated that it was red with a value of 3.06, subjective marbling was 2.8 %, and objective value was 2.9 %. Moisture varied from 690 to 739.3 g/kg, protein varied from 205.5 g/kg to 229. 6 g/kg and shear force (SF) was 2.87 kg/cm2 . There were no significant differences (P≥0.05) between the variables besides subjective marbling. Tukey´s test indicated that the lowest average included low and medium socioeconomic status supermarkets, which means that the fat content found in the chop eye is less than in meat in high socioeconomic level supermarkets. Conclusions and recommendations: According to the results, pork sold in the supermarkets in the Central Highlands of Mexico was a tender meat with reddish pink color, firm texture and little exudation and with an appropriate protein and intramuscular fat contents

Effect of organic selenium-enriched yeast supplementation in finishing sheep diet on carcasses microbiological contamination and meat physical characteristics

The aim of the current study was to evaluate the effect of feeding Pelibuey sheep on diet supplemented with different doses of organic selenium (Se)-enriched yeast on carcasses microbiological contamination and meat physical characteristics. The experiment was conducted during the finishing stage of 18 female sheep and lasted for 60 days. In a complete randomized design, sheep were distributed to one of three treatments: the control without Se-yeast (T1), the control supplemented with Se-yeast at 0.35 mg Se/kg DM (T2), and control supplemented with Se-yeast at 0.60 mg Se/kg DM (T3). The yeast product used was Selyeast 3000TM yeast (LFA Lesaffre, Toluca, Mexico) with a Se concentration of 3000 ppm (mg/kg). Lambs were slaughtered at the end of the experiment at an average weight of 39.5±4.41 kg and samples were taken for microbiological analysis. There were no differences between treatments (P>0.05) and the aerobic plate counts for T1, T2 and T3 had indexes of 0.10, 0.08 and 0.08 log10 CFU/cm2 , respectively. Total coliform counts obtained were 0.13, 0.10 and 0.09 log10 CFU/cm2 for T1, T2 and T3, respectively, and the faecal coliform counts were 0.09 log10 CFU/cm2 for T1, 0.06 log10 CFU/cm2 for T2 and 0.07 log10 CFU/cm2 for T3. No significant effects (P>0.05) were observed for carcasses physical characteristics of microbial growth, initial and ultimate pH and temperature, colour values and water holding capacity. It can therefore be concluded that organic Se-enriched yeast did not affect carcasses bacterial proliferation or meat physical characteristics.The authors wish to acknowledge the financial support to Mexican National Council for Science and Technology (CONACYT) Key Project 00000000011623

Bienestar y familia, una mirada desde la psicología positiva

Este libro está dirigido a estudiantes y profesionales en psicología y áreas afines, como enfermería, trabajo social o educación, y a los interesados en personalidad positiva. Cada capítulo se presenta de manera sencilla y con una estructura didáctica, pero sin perder rigor científico y calidad de la revisión, con el fin de facilitar el acceso a la información sobre bienestar individual, familiar y social de una forma accesible para adentrarnos al estudio de temas de psicología positiva. Dadas las temáticas, se consideró pertinente dividir este libro en dos secciones: I. Psicología positiva y bienestar. II. Bienestar individual y familiar.Universidad Autónoma del Estado de México y Ediciones y Gráficos Eón, S.A. de C.V
