    Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Ionizing radiation has been widely used in industrial processes, especially in the sterilization of medicals, pharmaceuticals, cosmetic products, and in food processing. Similar to other techniques of food processing, irradiation can induce certain alterations that can modify both the chemical composition and the nutritional value of foods. These changes depend on the food composition, the irradiation dose and factors such as temperature and presence or absence of oxygen in the irradiating environment. The sensitivity of vitamins to radiation is unpredictable and food vitamin losses during the irradiation are often substantial. The aim of this study was to discuss retention or loss of vitamins in several food products submitted to an irradiation process.52512671278Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

    Influencia da nutrição sobre a qualidade do pescado: especial referência aos ácidos graxos.

    Get PDF
    Reconhecida como uma fonte de proteína de alta qualidade, a carne de pescado tem sido objeto de inúmeras pesquisas relacionadas à sua composição em ácidos graxos, dentre os quais se encontram os popularmente conhecidos como ômega-3, os quais estão diretamente associados à saúde humana pelo seu efeito protetor, principalmente contra doenças cardiovasculares e reumatismo. Nesse sentido, um dos grandes desafios da aquicultura é apresentar ao consumidor um produto final que se assemelhe, em termos nutricionais e sensoriais, aos peixes capturados na natureza que são ricos em ácidos graxos. Este documento faz uma revisão da influência da nutrição nos peixes cultivados sobre a composição de ácidos graxos e a importância dessa como ferramenta para melhorar a qualidade nutricional e agregar valor ao pescado.bitstream/item/101804/1/DOC124.pd

    "Pacu" (Piaractus mesopotamicus), a freshwater fish, was used with the purpose of studying its quality when smoked, salted and dried, and canned. Waste flour was also analysed. Fish from a fish farm of Piracicaba,SP was used. The intended final use was children's school meal. The results of the analysis of the final products for moisture, protein, lipids, ash and NaCl, in percent, were, respectively, 11.36; 52.53; 18.31; 17.76; 16.25 for the salted and dried fish; 70.25; 23.80; 2.69; 3.13; 1.17 for smoked fish; 62.19; 18.59; 14.34; 2.79; 1.29 for canned fish and 15.73; 42.94; 20.91; 20.42 (NaCl not available) for the waste flour. The smoked and the canned fishes were submitted to taste panels. For the canned product the results were: aspect in the can: 89% excellent and 11% good; aspect on plate: 56% excellent and 44% good; odor: 67% excellent and 33% good; taste: 56% excellent, 33% good and 11% regular and texture: 22% excellent, 56% good and 22% regular (none of the above got the not acceptable note). For the smoked fish the results were, aspect: 45% excellent and 55% good; odor: 35% excellent, 60% good and 5% regular; taste: 25% excellent, 55% good and 20% regular and texture: 50% excellent and 50% good (none got not acceptable grade)

    Assessing fish consumption is complex and involves several factors; however, the use of questionnaires in surveys and the use of the Internet as tool to collect data have been considered promising approaches. Therefore, the objective of this research was to design a data collection technique using a questionnaire to assess fish consumption by making it available on a specific home page on the Internet. A bibliographical survey or review was carried out to identify the features of the instrument, and therefore pre-tests were conducted with previous instruments, followed by the Focus Group technique. Specialists then performed an analysis and conducted an online pre-test. Multivariate data analysis was applied using the SmartPLS software. The results indicate that 1.966 participants belonging to the University of São Paulo (USP) community participated in the test, and after the exclusion of some variables, a statistically significant results were obtained. The final constructs comprised consumption, quality, and general characteristics. The instrument consisted of behavioral statements in a 5-point Likert scale and multiple-choice questions. The Cronbach's alpha reliability coefficient was 0.66 for general characteristics, 0.98 for quality, and 0.91 for consumption, which indicate good reliability of the instrument. In conclusion, the results proved that the Internet assessment is efficient. The instrument of analysis allowed us to better understand the process of buying and consuming fish in the country, and it can be used as base for further research.342315323Bargas-Avila, J.A., Lotscher, J., Orsini, S., Opwis, K., Intranet satisfaction questionnaire: Development and validation of a questionnaire to measure user satisfaction with the Intranet (2009) Computers In Human Behavior, 25 (6), pp. 1241-1250. , http://dx.doi.org/10.1016/j.chb.2009.05.014Batagelj, Z., Vehovar, V., Technical and methodological issues in surveys (1998) Proceedings of the 53° Annual Conference of the American Association For Public Opinion Research (AAPOR), , http://www.ris.org/ris98/stlouis, St. Louis.

    Application Of Exploratory Factor Analysis To Assess Fish Consumption In A University Community [aplicação De Análise Fatorial Exploratória Para Avaliar O Consumo De Pescado Em Uma Comunidade Universitária]

    Get PDF
    The objective of this research was to use the technique of Exploratory Factor Analysis (EFA) for the adequacy of a tool for the assessment of fish consumption and the characteristics involved in this process. Data were collected during a campaign to encourage fish consumption in Brazil with the voluntarily participation of members of a university community. An assessment instrument consisting of multiple-choice questions and a five-point Likert scale was designed and used to measure the importance of certain attributes that influence the choice and consumption of fish. This study sample was composed of of 224 individuals, the majority were women (65.6%). With regard to the frequency of fish consumption, 37.67% of the volunteers interviewed said they consume the product two or three times a month, and 29.6% once a week. The Exploratory Factor Analysis (EFA) was used to group the variables; the extraction was made using the principal components and the rotation using the Quartimax method. The results show clusters in two main constructs, quality and consumption with Cronbach Alpha coefficients of 0.75 and 0.69, respectively, indicating good internal consistency.33199106Alves, A.L.S., Padrão alimentar de mulheres adultas (2006) Revista De Saúde Pública, 40 (5), pp. 865-873. , PMid:17301909Anastasi, A., Urbina, S., (2000) Testagem Psicológica, p. 575. , 7. ed.

    Recomendações técnicas para o processamento da tilápia.

    A tilápia nilótica (Oreochromis niloticus) é uma espécie bastante promissora quanto ao cultivo e deve garantir a disponibilidade de pescado em qualquer região do Brasil. Foi introduzida no Brasil em 1971, em açudes do Nordeste, e difundiu-se para todo o País. Seu cultivo está crescendo rapidamente, em função da sua rusticidade, da possibilidade de seu cultivo com baixos níveis de proteínas das rações, das elevadas taxas de crescimento que podem ser obtidas em diferentes regimes de criação, inclusive em altas densidades, da elevada resistência a doenças, da sua boa aceitação no mercado, em virtude da qualidade de sua carne, da excelente textura e paladar, do rendimento na filetagem e da ausência de espinhos intramusculares em seu filé. Em apenas três anos, sua produção dobrou e hoje, produz-se, aproximadamente, 132 mil de toneladas/ano. Desse modo, este documento vai tratar exclusivamente da elaboração de um programa de rastreabilidade e das tecnologias aplicadas à depuração, desenvolvimento de produtos e embalagens e elaboração de coprodutos que contribuam para o estabelecimento da tilapicultura brasileira. Esse manual foi baseado nas pesquisas desenvolvidas pela equipe do GETEPE - Grupo de Estudos e Extensão em Inovação Tecnológica e Qualidade do Pescado da ESALQ-USP, com apoio da Embrapa, por meio do projeto AQUABRASIL.bitstream/item/83628/1/Doc-213-Rastreabilidade-com-capa.pd
