Abstract The fish processing processes generate a large volume of residues, so, an alternative for the use is the production of minced fish (MF). Thus, this study aimed to develop breaded with different concentrations of MF of salmon and tilapia fillet, and to analyze the chemical, physical and microbiological characteristics, as well as to determine the acceptability and purchase intention of the formulations. In technological and nutritional terms, the use of salmon MF in the production of breaded products did not detract from the quality of the final product, indicating a viable alternative for the use of salmon waste.

Abstract Temperate fruit species, originate from regions with cold winters and well-defined climatic seasons. These fruits are also produced in subtropical and tropical regions. The aim of this study was to determine the bioactive compounds and antioxidant activity of different fruit cultivars from fruit trees of temperate climate, such as peach, pear, quince, and fig, able to be produced in subtropic regions. Analyzes of antioxidant activity, total phenolics and ascorbic acid were carried out. In peaches, ‘Biuti’ had the highest phenolic content, and ‘Bonão’ stood out in relation of antioxidant activity (ABTS) and ascorbic acid. For quinces, 'Lageado' had higher phenolic content, ‘Provence’ and ‘CTS’ showed higher antioxidant activity (ABTS), and ‘Alaranjado’ stood out in relation of antioxidant activity (DPPH). ‘Fuller’, ‘Smyrna’ and ‘Portugal’ are the ones with the highest levels of ascorbic acid. In pears, ‘Seleta’ showed the highest phenolic content, antioxidant activity (DPPH) and ascorbic acid. ‘Centenaria’ presented the highest antioxidant activity (ABTS). In figs, ‘Três num Prato’, ‘Lemon’ and ‘Brunswick’ had the highest ascorbic acid content. ‘Três num prato’ and ‘Roxo de Valinhos’ showed the highest phenolic content and antioxidant activity consecutively. It was found that cultivars of these evaluated fruits showed great variability, even under similar conditions.

Resumo: O objetivo deste trabalho foi avaliar a influência de cultivares de figueiras (Ficus carica) cultivadas em regiões subtropicais nas características físico-químicas, reológicas e sensoriais dos doces de figos em conserva. Os frutos frescos das cultivares foram analisados quanto a comprimento, diâmetro, massa unitária, sólidos solúveis totais, acidez total titulável, pH, relação sólidos solúveis totais/acidez total titulável e cor. Os figos em conserva foram avaliados quanto a acidez titulável, pH, cor, perfil de textura e características sensoriais. As diferentes características físico-químicas dos figos frescos influenciaram as dos frutos em conserva obtidos. Os figos em conserva de 'Lemon' e 'Pingo de Mel' apresentaram os menores e os maiores pH, respectivamente, enquanto os de 'Troiano' apresentaram a maior acidez total titulável. Em relação à cor, após o processamento, os figos em conserva, no geral, apresentaram coloração mais esverdeada e escura que o fruto fresco. Os figos em conserva obtidos de 'Brunswick' e 'Troiano' tiveram a menor aceitação e os de 'Bêbera Branca' e 'Roxo de Valinhos', a maior. Figos em conserva menos ácidos e mais macios são mais amplamente aceitos, o que pode ser obtido de todas as cultivares, exceto de Brunswick e Troiano.

Abstract: The objective of this work was to evaluate the influence of fig (Ficus carica) cultivars grown in subtropical regions on the physicochemical, rheological, and sensorial characteristics of the canned figs. Fresh fruits of the cultivars were analyzed for length, diameter, unit mass, total soluble solids, total titratable acidity, pH, total soluble solids/total titratable acidity ratio, and color. Canned figs were evaluated for titratable acidity, pH, color, texture profile, and sensory characteristics. The different physicochemical characteristics of the fresh figs influenced those of the obtained canned fruits. The canned figs from 'Lemon' and 'Pingo de Mel' presented the lowest and highest pH, respectively, whereas those from 'Troiano' showed the highest total titratable acidity. As for color, after processing, the canned figs, in general, presented a more greenish and darker color than the fresh fruits. The canned figs from 'Brunswick' and 'Troiano' had the lowest acceptance, whereas those from 'Bêbera Branca' and 'Roxo de Valinhos', the greatest. Less acid and softer canned figs are more widely accepted, which can be obtained from all cultivars, except from Brunswick and Troiano.

Resumo Com o intuito de agregar valor ao produto final, e visando a identificar quais cultivares implantadas em regiões tropicais são mais apropriadas para o processamento de marmeladas, o objetivo deste estudo foi caracterizar e avaliar a influência de diferentes cultivares de marmeleiro (‘Fuller’, ‘Smyrna’, ‘Portugal’, ‘Provence’, ‘Mendonza Inta-37’, ‘Alaranjado’, ‘Lajeado’, ‘CTS 207’, ‘D’Angers’ e ‘Bereczy’), cultivados em regiões tropicais do Brasil, sobre as características físico-químicas, propriedades reológicas e aceitação sensorial da marmelada obtida. As diferentes cultivares de marmelo apresentaram grande variabilidade entre si em relação às características físicas e físico-químicas. Entretanto, as cultivares estudadas deram origem a marmeladas muito semelhantes entre si que apresentaram alta aceitação sensorial, com exceção da cultivar Mendonza Inta-37, que deu origem a uma marmelada menos aceita.

Abstract With the purpose of adding value to the final product and aiming to identify which cultivars implanted in tropical regions are more appropriate for the processing of marmelade, the objective of this study was to characterize and evaluate the influence of different cultivars of quince (‘Fuller’, ‘Smyrna’, ‘Portugal’, ‘Provence’, ‘Mendonza Inta-37’, ‘Alaranjado’, ‘Lajeado’, ‘CTS 207’, ‘D’Angers’ and ‘Bereczy’) grown in tropical Brazilian regions, on the physical-chemical characteristics, rheological properties and the consumer acceptance of the obtained marmelade. The different quince cultivars presented great variability among themselves in relation to physical and physicochemical characteristics. However, the cultivars studied gave rise to marmelades that were similar to each other, which had a high sensory acceptance, except for the cultivar Mendonza Inta-37, which resulted in a less accepted marmelade.
