A complete characterization of yacon syrup was performed by analytical techniques, including NMR and UPLC-QTOF-MS. The effect of the different stages of yacon syrup production on fructooligosaccharides (FOS) and chlorogenic acid (CGA) contents were also evaluated. As a result, in addition to higher levels of FOS and CGA, some mineral elements, such as K, Ca and P, and essential amino acids, such as tryptophan, valine, and threonine, were determined in yacon syrup. Twenty-five compounds were putatively identified, and the main compounds were phenolics derived from quinic and trans-cinnamic acids. Considering the different stages of yacon syrup production, the results indicate that the contents of FOS and CGA were maintained in the pulping, enzymatic maceration and microfiltration, leading to a concentration of these components in the last stage of processing (vacuum concentration). These results will be used to fortify this innovative and promising product in the area of functional foods.

<p>A cerveja é a bebida alcoólica mais consumida no mundo. Estando bem relacionado com festividades e comemorações, porém essa bebida contém uma variedade de compostos bioativos, vitaminas e minerais, capazes de promover benefícios quando a sua ingestão é feita de maneira moderada. O mercado está a cada dia buscando produtos diferenciados e até exclusivos, surge assim o campo das cervejas artesanais. O objetivo deste trabalho foi desenvolver uma cerveja artesanal com acerola e abacaxi, trazendo uma nova alternativa ao nicho de mercado, além da associação ao aumento de suas características funcionais. O experimento foi conduzido no Laboratório de Cereais, Universidade Federal do Ceará – UFC, onde a cerveja foi produzida em escala laboratorial passando pelos processos de moagem do malte, mosturação, cozimento, decantação, filtração, fermentação, envase, maturação e <em>primming</em>, sendo adicionada a polpa de fruta em percentagem definidas por DIC, pasteurização e armazenamento. As amostras foram submetidas à análise físico-química, microbiológica e sensorial. Os resultados foram submetidos ao teste de normalidade, ao teste de média tukey e a ANOVA pelo software STATISTIC 10. A utilização das polpas de abacaxi e acerola como adjuntos no processamento da cerveja mostrou-se uma alternativa viável demostrada pelos resultados satisfatórios na avaliação sensorial, além de características físico-químicas de uma cerveja artesanal ácida/frutada.<strong></strong></p><p> </p><p align="center"><strong><em>Development of craftbeer with Acerola </em></strong><strong>(</strong><em>Malpighia emarginata</em> <em>DC</em><strong>) </strong><strong><em>and pineapple </em></strong><strong>(</strong><em>Ananas</em> <em>comosus L.</em> <em>Merril</em><strong>)</strong><strong><em></em></strong></p><pre><strong>Abstract: </strong>The beer is the most consumed alcoholic beverage in the world. It is well associated with holidays and celebrations, but this beverage contains a variety of bioactive compounds, vitamins and minerals that promote benefits when its intake is made moderate manner. The market is every day looking for different and even unique products, thus arises the field of craft beers. The objective of this study was to develop a craft beer with pineapple and acerola, it brings a new alternative in this niche market, in addition to membership in increasing their functional characteristics. The experiment was conducted at the Cereals Laboratory, Federal University of Ceará - UFC, where beer was produced in laboratory scale past the malt milling processes, mashing, baking, decantation, filtration, fermentation, bottling, maturation and primming, where he was added to fruit pulp as a percentage defined by DIC, pasteurization and storage. The samples were subjected to physical-chemical and sensory analysis. The results were submitted to normality test, the mean test Tukey and the ANOVA by STATISTIC 10 software. The use of pineapple pulp and acerola as adjunct in beer processing was considered a viable alternative due to satisfactory results in the sensory evaluation, as well as physical and chemical characteristics that have proven a craft beer with sour / fruity characteristics.</pre>

O presente trabalho teve como objetivo utilizar farinha de maracujá e de aveia como ingredientes funcionais no processamento de cookies. Foram processadas 03 formulações de bolo de milho com adição de concentrações crescentes de farinha de maracujá (5%, 7,5% e 10%) e 15% de farelo de aveia. O controle consistiu de uma formulação padrão de bolo de milho, sem farinha de maracujá e farelo de aveia. As diferentes formulações foram avaliadas sensorialmente. Foram efetuados testes sensoriais de aceitação global e aceitação por atributos (sabor, aparência e textura). O bolo que apresentou melhor resultado geral na análise sensorial foi a de 5% de adição de farinha de maracujá, sendo reduzida a aceitação dos bolos das outras formulações, à medida que se incrementava a concentração dessa farinha. Adicionalmente, a formulação de 5%, também apresentou melhores resultados em relação aos atributos aparência, sabor, aceitação global, menor valor calórico e maior intenção de compra.

Response surface methodology (RSM) was employed for the analysis of the effects of the simultaneous enzymatic treatment using pectinolytic and cellulolytic enzyme at different concentrations, agitation, and temperature, on 13 physical and chemical characteristics of yacon pulp. After microfiltration, the characteristics of permeate flow and turbidity were also evaluated. The results indicated that the enzymatic process has been successfully employed, and the recommended conditions treatments were: enzyme concentration of 500 mg/L of Pectinex® Ultra SP‐L and Celluclast® 1.5 L, at 45 °C, and 175 rpm, during 120 min. In this optimized conditions, the permeate flow was almost 40% higher than the control A (without enzymatic treatment). As results, a limpid material with high levels of fructooligosaccharides and chlorogenic acid were obtained. The use of his clarified yacon juice in ready to drink formulations and as food ingredient for other products development is subject of further studies. Practical applications Yacon is rich in bioactive compounds, such as chlorogenic acid (CGA) and fructooligosaccharides (FOS), which present a positive relationship with human healthy. The clarified yacon is a versatile product, which could be used in ready to drink formulations or as food ingredient for other products. However, to obtain this microfiltered product, the bioactive compounds could be negatively affected by the process. In this sense, this work discussed the influences of the main conditions to produce clarified yacon, optimizing this condition and producing a clarified yacon juice high levels of CGA and FOS. The end‐product may have potential use for food industries, especially due to the prebiotic properties.
