Physical-chemical changes in ice cream with agro-industrial by-products: a review
Ice cream is a very popular dessert in Brazil. However, in the last decade, consumers in the country have been increasingly concerned about their health and are looking for healthier foods. To meet this demand, several authors have been researching the application of agricultural by-products to develop foods with reduced fat and sugar content. Thus, the objective of this work was to carry out a bibliographic review, over the last 15 years, on the physical-chemical and sensory changes that can occur in ice cream formulations with the addition of agro-industrial by-products such as bran, peels, and bagasse from different groups of vegetables, such as roots, fruits, and vegetables, as well as by-products of manufactured products such as wine and cheese. The addition of these products as ingredients for the replacement of fat, flavoring, or stabilizing agent, resulted in products with similar or superior acceptance to traditional ice creams. The results demonstrated the potential of using these by-products in the production of functional ice creams, which produce added value when applying discards as new ingredients, however, it is still necessary to carry out more research to improve the formulations and the application of other by-products
RESPOSTA FRACTAL DA VARIABILIDADE DA FREQUÊNCIA CARDÍACA NO TESTE DO DEGRAU DE 6 MINUTOS EM PACIENTES COM DOENÇA PULMONAR OBSTRUTIVA CRÔNICA
Introdução: Pacientes DPOC apresentam alterações na variabilidade da frequência cardíaca (VFC) podendo ser avaliados pelos índices Alpha1 (α1) e Alpha2 (α2) de propriedade fractal. Objetivo: Avaliar a resposta da VFC pela análise não linear frente ao teste do degrau de 6 minutos (TD6m) em pacientes DPOC. Métodos: Estudo transversal, incluiu 11 pacientes DPOC de moderado a muito grave sem arritmia cardíaca. A FC foi registrada com cardiofrequencímetro Polar® durante o repouso (rep=5 minutos) e recuperação (rec=5 minutos pós-teste). Os dados foram analisados no software Kubios-2.2. Para determinar a retomada vagal calculou-se delta de variação entre a FC_pico subtraindo a FC_recuperação no 1º minuto pós_teste (FCRec=FC_pico - FC_recuperada). No TD6m utilizou-se um degrau de 20cm de altura e os pacientes foram orientados a descer e subir o maior número de degraus em cadência livre. Os resultados foram analisados no SPSS-23.0, considerando significativo p≤0,05. Resultados: Os pacientes subiram 80,2±19,6 degraus no TD6m. Nenhuma diferença entre repouso e recuperação para α1 (p=0,117) e α2 (p=0,199). Identificamos diferenças na FC_repouso para FC_pico do TD6m (rep=78,9±10,5 vs pico=109,0±13,9 bpm,
