Influência do uso simultâneo de ácido ascórbico e azodicarbonamida na qualidade do pão francês The influence of simultaneous use of ascorbic acid and azodicarbonamide in the quality of french bread

Este trabalho teve como objetivo avaliar o uso simultâneo de ácido ascórbico e azodicarbonamida em produto de panificação e através da metodologia de superfície de resposta. As respostas do planejamento experimental (2²) foram: o volume específico e a pontuação total das características externas e internas do pão francês. A ação do ácido ascórbico no aumento do volume específico do pão francês teve efeitos significativos (p < 0,05 ou valores próximos) linear e quadrático. Para a azodicarbonamida verificou-se somente efeito quadrático (p < 0,05 ou valores próximos), e não houve qualquer efeito de interação entre os dois agentes oxidantes estudados. A aplicação de ácido ascórbico e azodicarbonamida em concentrações acima de 75 mg.kg -1 de farinha de trigo e 30 mg.kg -1, dentro dos níveis estudados, proporcionou a produção de pães franceses de maior volume específico.<br>The aim of this work was to evaluate the simultaneous use of ascorbic acid and azodicarbonamide in a bakery product by using the response of the surface methodology. The experimental design (2²) responses were the specific volume and total count of the external and internal characteristics of French bread. The action of ascorbic acid on the increase of the specific volume of French bread had significant linear and quadratic effects (p < 0.05 or near values). For azodicarbonamide, the quadratic effect was observed, and there was no interaction effect between the two studied oxidants agents. The application of ascorbic acid and azodicarbonamide using concentrations above 75 mg.kg -1 of wheat flour and 30mg.kg -1, considering the studied levels, provided French bread production with a higher specific volume

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
