Heme iron has a higher bioavailability. The investigation aimed to elaborate pasteurized milk with fortified chocolate flavor with heme iron that has good sensory acceptability. The preparation of the flavored milk was carried out based on the regulations and heme iron, obtained from a commercial source of whole blood of porcine origin, was added before the pasteurization process to achieve its complete dilution. The concentration of iron and chocolate flavoring was established as variables in order to evaluate the optimal formulation based on Sensory Acceptability (SA). The experimental design was a 32 factorial design in which eight formulations were established, which were sensory acceptability evaluated by a total of 35 school-age children, aged between 8 and 11 years using a five-point facial hedonic scale. The results of the analysis of variance and optimization of the response showed that SA was 4.71 (on a scale of 1 to 5) for a fortification of 6.76 mg Fe kg-1 sample and a chocolate concentration of 2.0 g kg-1 sample. The physicochemical characterization indicated a higher percentage of carbohydrates, a higher concentration of iron (9.3 mg Fe kg-1 sample) and vitamin C (349.0 mg kg-1 sample) with respect to fresh milk. According to the physicochemical and microbiological results, the approximate life time of the beverage was 5 days, which is in accordance with Peruvian regulations. These results showed a method of fortification of flavored milk that allowed the use of heme iron, whose content could contribute to the daily requirement of this mineral in children aged between 8 and 11 years old (8 mg of iron per day).","PeriodicalId":9112,"journal":{"name":"Brazilian Journal of Food Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67145118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study aimed to evaluate the conservation of minimally processed pinhão using edible chitosan and gelatin coatings. The pinhões were minimally processed and coated with chitosan, gelatin and chitosan/gelatin using the Layer-by-Layer (LbL) technique. They were then dried under forced ventilation, packaged in a polyethylene terephthalate package and stored at 4 °C for 10 days. The analyses performed were weight loss, pH, reducing sugars, vitamin C, color, microbiological analysis and sensory analysis. Benefits were observed with the use of chitosan and gelatin coatings, especially when applied using the LbL technique. The best combination of results was obtained with the application of the chitosan/gelatin coating, mainly reduction of weight loss and inhibition of growth of fungi and aerobic psychrotrophic bacteria. The coating did not retard the maturation process, thus, higher vitamin C contents were obtained. The coatings did not influence the taste and aroma of minimally processed pinhão. Minimal processing can encourage the consumption of seeds, besides this, the conservation using edible coating based on chitosan/gelatin, applied with the LbL technique associated with refrigeration, extended their shelf life.","PeriodicalId":9112,"journal":{"name":"Brazilian Journal of Food Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67141903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Drying is a fundamental process in the food industry, especially for highly perishable foods, such as fruits and vegetables, because they tend to have short durability post-harvest, resulting in economic and environmental losses. The Refractance Window (RW) is a suitable technique for fruits and vegetables as it maintains the nutritional quality of the raw material in the dry product. Although RW is more energy-efficient than hot air-based techniques, the equipment traditionally consumes electricity, largely obtained from fossil fuels, emitting polluting gases. As a solution to this problem, hybridization of the heating system can be adopted in the drying process. Hybridization is when two or more heat transfer techniques are used in food dehydration. Renewable alternatives, such as solar energy, represents a clean and abundant energy source. The integration of these technologies (RW with solar energy) represents a technological improvement for the food industry, especially regarding environmental concerns. The present study analyzed the current progress in the integration of renewable energies into traditional RW for the drying of fruits and vegetables, as well as highlighted the existing knowledge","PeriodicalId":9112,"journal":{"name":"Brazilian Journal of Food Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67143846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aimed to evaluate the influence of different processing methods on the quantification of phenolic and anthocyanin compounds and on the antioxidant activity of R. brasiliensis fruits. The plants were processed by different ways - the extracts of fruits were obtained by Spray Dryer (SD) or Lyophilization (LYO), and the fruits were dried directly in an oven (OD) and were also evaluated after freshly thawed (FT). The processing methods were independent. After processing, the polyphenol and anthocyanin contents and antioxidant activity were evaluated. The Total Phenolic Content (TPC) was assessed using the Folin-Ciocalteu technique. The pH differential method was used for quantification of anthocyanin and the antioxidant activity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. R. brasiliensis fruits have a high content of polyphenols and anthocyanins, and an expressive antioxidant activity that can bring benefits to the population. The FT fruits showed the lowest content of total polyphenols. However, the OD fruits showed the most interesting results, since the total polyphenols and anthocyanins contents and the antioxidant activity were similar to the other processing methods performed in this work and were more economically viable. Obtain a bioactive content and adequate antioxidant activity after simple processing such as drying is very interesting when using these fruits for longer, or even, obtaining pharmaceutical formulations. It could be determined, for the first time, the content of polyphenols and anthocyanins and the antioxidant activity of the fruits of R. brasiliensis, as well as the best way to process these fruits by drying them in an oven.","PeriodicalId":9112,"journal":{"name":"Brazilian Journal of Food Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67145944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Este estudo teve como objetivo avaliar a adequação dos rótulos de suplementos alimentares whey protein comercializados em Fortaleza, Ceará. Aplicou-se um check list baseado na Resolução da Diretoria Colegiada nº 243/2018 em 51 rótulos de suplementos, avaliados em cinco lojas especializadas em produtos nutricionais, sendo excluídos produtos com data de fabricação anterior a julho de 2018 e em idioma estrangeiro sem tradução. Os rótulos analisados foram de 29 marcas diferentes, sendo 25 (92%) de fabricação nacional e quatro (8%) importados. Foram encontradas não conformidades nos parâmetros analisados referentes à formatação da disposição e ao aspecto de caracteres da designação do produto, tais como cor contrastante com o fundo do rótulo, legibilidade da designação, localização da designação do produto, designação em negrito e designação complementada com a fonte do nutriente da qual foi extraído e do modo de uso. Além disso, muitos produtos analisados não apresentaram informações sobre a conservação após a abertura da embalagem. Em relação à designação do produto “suplemento alimentar”, apenas dois (4%) estavam adequados.
