We studied medicinal plants expended in five major markets, San Pedro, San Jerónimo, Ttio, Wanchaq and four small zonal, Rosaspata, San Sebastian, Molino II, Huancaro and Santa Rosa, in the city of Cusco. It was aimed to know the richness, how to use treated conditions, place of origin, distributions and source. We recorded 152 species into 45 families, the families more riches were Asteraceae with 36 species and Lamiaceae (12), species most frequently bought and sold in all markets were Muehlenbeckia volcanica (Benth.) Endl. "Mullaca" Perezia virens (D. Don) Hook. & Arn. "Valeriana", Matricaria recutita L. "Manzanilla" and Hypochaeris taraxacoides (Walp.) B. & H. "Pilli pilli", the herbaceous habit represent 75%,the total of the parts used, 81% correspond to the entire plant, the infusions or "mates calientes" with 69% of the mode of preparation and conditions treated most freq...

Recently, artisanal masses of pilar corn have become a food for mass consumption in Venezuela, without adequate sanitary control in terms of production and sale. There are very few internationally referenced studies and none recently locally, regarding this product; for this reason, the objective of this research has focused on its microbiological evaluation with samples obtained in the municipal market of Puerto La Cruz, which are the main point of sale of the same in the main Venezuelan cities. The frequencies of total coliforms, fecal coliforms, presence of Escherichia coli, aerobic mesophiles and Staphylococcus aureus were determined as indicators of inadequate manipulation; The presence of molds and yeasts was also considered as microorganisms associated with cereals. It is concluded that all the samples of pillared corn masses present a high level of these indicator microorganisms ...

The objective of the study was to determine the presence of antimicrobial residues in bovine muscle tissue and kidneys expended in supermarkets of the Piura city, Peru. 100 muscle tissue samples were collected from the loin and tip of the hip, free of fat and aponeurosis, and 100 samples from kidneys. From each sample obtained, 8 mm diameter and 2 mm thick pieces were analyzed and deposited on a culture medium mixed with Bacillus subtilis spores adjusted to pH 6.0; 7.2 and 8.0. Based on the size of the growth inhibition halo of the strain, it was found that 23 samples were positive for the detection of antimicrobial residues. 5% (5/100) corresponded to muscle tissue samples and 18% (18/100) to kidneys. The highest number of positive samples was obtained in supermarkets I (2 for muscle tissue and 7 for kidney) and II (2 for muscle tissue and 6 for kidney). The mean and standard deviation ...

The research was conducted in order to evaluate the knowledge of consumers about the nutritional labeling of foods sold in the city of Iquitos. The study was qualitative, non-experimental with a simple descriptive design. We worked with 385 people, obtained by random sampling the survey was used to collect data, ask a question and provide answer options. It was observed that 5.7% (n=22) never read, 31.7% (n=122) sometimes read and 19.5% (n=75) always read; 80.3% (n=309) have low knowledge level, 17.6% (n=68) medium and 2.1% (n=8) high. The choice of foods by the consumer considering the declaration and information in the nutritional labeling of foods, it was observed that 0.5% (n = 2) of them choose foods according to the statement on the label, 58.1% (n = 224) often get to choose and 5.5% (n = 21) always choose foods taking into account the declaration and information; demonstrated by e...

The aim of this paper is to describe the study of Political Com- munication historiographically, showing its theoretical evolution. Political communication involves thinking of a discipline that has several theoretical approaches and schools of thought that, from the social sciences, politics, communication and sociology, have contributed to the construction of po- litical communication as a new academic discipline. Therefore, this paper seeks to contribute to the current discussions on the origin, definitions and approaches to analysis on political communication, which for many is con- sidered an illegitimate and trivial discipline, but which at the moment is in the center of the study of modern democracies from the remarkable crisis of political representation and political disaffection, the lack of political ideolo- gies and high personalization and especially the new forms of communi...

Simulation and optimization was carried out using the CHEMCAD 5.2.0 program of an Ammonia Plant using Natural Gas as raw material. The objective of this project is to carry out the calculation and sizing of a plant for the production of 334,000 tons / year of ammonia, from natural gas as raw materials. Considering an average of 1000 tn / day (334 days) of operation of the plant, 41.6 tn / h of NH3 would be obtained, using the CHEMCAD program to determine the optimal variables in each stage. The ammonia produced will be used as raw material to produce fertilizers and other products. Five stages of the process were determined: Reform, Conversion, Purification, Metanation and Ammonia Loop. For each stage the optimum temperature and pressure of operation was determined using the program, as well as the balance of matter and energy in addition to the operation design of each equipment. In add...

At present in the Region of Martin, is observed a low domestic consumption of the oil of sacha inchi by the scanty promotion of the product and the deficient development of commercial strategies of the managerial sector. For this reason, the aim of the present work of investigation is orientated to structure a commercial strategy using the theories: marketing and sale, strategies of marketing and the consuming behavior to increase his consumption. Given the lack in general of the Omega-3 in our diets, the oil of sacha inchi represents one of the best and more important sources of this essential nutrient that is available nowadays and that is a choice succeeded for any person who is interested in feeding correctly and supporting a good health. Nevertheless to the existence of companies that they dedicate to the production, transformation and commercialization of the oil of sacha inchi tha...

This study was conducted to evaluate the contamination for parasites in the frog Telmatobius jelskii, used in the preparation of extracts intended for direct human consumption in the form of beverages expended in public areas. Frogs (n=84) were taken in 21 food carts in Lime city center. Direct coproparasitological techniques and the Travassos technique were used for the detection of gastrointestinal parasites. For the detection of metazoan parasites the small and large intestine, liver, lung and bladder were revised. All frogs had parasites of at least three species, identifying the presence of two digenea: Gorgoderina attenuata (7.2%) and Gorgoderina sp (11.9%), two nematodes: Hedruris heyeri (100%) and Capillaria sp (6.0%) and two zoonotic protozoa: Cryptosporidium sp (100%) and Balantidium sp (100%). The results showed high contamination with parasites in frogs that are used in the p...

Aflatoxins cause a variety of disorders in poultry, especially affecting the liver (aflatoxicosis). Contaminated livers may become a health risk to consumers when expended in food markets. The purpose of the present study was to detect the presence of aflatoxins in chicken livers in Lima food markets. Samples were collected in 16 markets located in various socioeconomic sectors of Lima. From every market livers were subclassified as normal and apparently suspicious. Analysis of 32 samples was conducted at the Laboratory of Biochemistry, Nutrition and Animal Feeding, Veterinary Medicine Faculty, San Marcos University. Aflatoxins were determined through the ELISA method approved by the AOAC Research Institute, using the Veratox HS (high sensitivity, 0, 1, 2, 4, and 8 ppb). Liver samples are quite complex so immunoaffinity extraction columns (NEOCOLUMN for aflatoxins, 04/08) were used. The ...
