The objective of this study was to assess the perceptions (using the preferred attribute elicitation [PAE] methodology) and acceptance of frozen dessert processed with water‐soluble extract of rice byproduct and added with prebiotic components (long‐chain inulin, medium‐chain inulin, oligofructose, or polydextrose, 5 g/100 g) by vegan or nonvegan consumers. Most of the elicited attributes (9 out of 13 attributes, yellow color, brightness, creamy appearance, passion fruit aroma, sweet taste, passion fruit flavor, acid taste, sour taste, and creamy texture) were considered important for the characterization and/or acceptance of the frozen dessert formulations by both groups (vegan and nonvegan), but the order of importance was different between the groups. The sensory profile (Rv = 0.48, P = 0.03 in MFA) of the frozen dessert formulations was similar between vegan and nonvegan groups, and polydextrose contributed to increase firmness/consistency of the frozen dessert, while long‐chain inulin contributed to the increase in the creaminess of the products. Finally, oligofructose and polydextrose could reduce the sour taste of the products. The consumers gave scores from 6 to 8 in a 9‐point hedonic scale for the products, suggesting suitable acceptance. However, vegan consumers gave lower scores for the same products. In conclusion, PAE methodology can be used to compare the perception of different consumer groups, and vegan and nonvegan consumers have a similar perception about prebiotic frozen dessert processed with water‐soluble extract of rice byproduct. Furthermore, the frozen dessert developed had suitable consumer acceptance, although vegan gave lower scores than nonvegan consumers.Practical ApplicationThis is the first study involving the development of prebiotic frozen dessert from water‐soluble extract of rice byproduct and application of PAE to assess the sensory perception of vegan and nonvegan consumers. The results are important for the industry as they indicate that the PAE methodology can be used to characterize food products, compare the perception of different consumer groups, and elicit attributes that are important for the products, suggesting that universal marketing strategies could be used and that the developed frozen dessert could serve both vegan consumers and those on conventional diets.

Honey has numerous uses and composes formulations of many food, pharmaceutical, and cosmetic products due to its chemical, biological, and sensorial characteristics. In recent years, several reports and scientific articles claim the contamination of honey by antibiotics, a fact that is a public health problem since the ingestion of them can cause several side effects. In this sense, the purpose of this work was to carry out a literature review in international circulation databases about the contamination of honey by antibiotics in the last 10 years. It is observed in the literature that several quality control methods for evaluating this product have been developed, with the main objective of detecting trace concentrations of these compounds. In this context, the chromatographic techniques, rapid tests, immunoassays, and the use of emerging technologies that are considered sustainable for sample preparation stand out. When these methods are applied to honey samples, it is clear that the contamination of honeys by antibiotic residues has been growing every year, making it evident that programs for continuous monitoring of these residues in honeys are conducted. Also, not only has the amount of antibiotics increased, but also the diversity of assets being used. Regarding the residues present, the main antibiotics found in the evaluated samples belong to the class of tetracyclines, sulfonamides, aminoglycosides, macrolides, and amphenicols. However, few countries report maximum residue limits (MRL) allowed for these substances in honey, and in Brazil, as well as in the European Union, no MRL has been established for antibiotics in this product so far, which indicates that it is extremely important that MRL be adopted to ensure food safety for consumers.

Beet is a vegetable rich in antioxidant activity and phenolic compounds, besides being used as a natural dye, which has as a disadvantage the instability in relation to several factors, such as temperature, pH, oxygen and light. Therefore, this work aimed to microencapsulate the beet dye, evaluate the stability of powders and their application in yogurt. Beet extract was encapsulated in a combination of maltodextrin and xanthan gum, with subsequent drying in spray dryer or lyophilizer. In the powders obtained, color parameters, betanin content, phenolic compounds content, yield, microcapsule morphology and powder storage stability were evaluated for 40 days, with light, temperature and oxygen variation. The samples with the best results were applied in yogurt and the products were evaluated sensorially. The performance of powders dried by spray dryer was approximately 43% lower than lyophilized, with no variation in moisture content and soluble solids. Morphologically the samples dried by spray dryer were different from those dried by lyophilization. The content of phenolic compounds in the powders showed an increase after 40 days of storage in all samples, while the content of betanin showed a considerable drop in the first 7 days, followed by stability up to 40 days. With respect to color the parameter a*, was stable in storage, and the samples dried by spray dryer showed a higher value than the samples dried by lyophilization. The samples lyophilized with maltodextrin and with xanthan gum were added to the yoghurt, both in concentrations 0.5 and 1%. There was no significant difference between the yogurt samples prepared with the powders both in the sensory analysis and in the physical-chemical analysis, except for the ashes. Therefore, all the microcapsules evaluated presented good encapsulation efficiency and good stability during the 40 days evaluated.

O amido é um importante composto na alimentação humana, pois é uma fonte energética de grande relevância. Porém, o amido nativo apresenta certas limitações que dificultam a sua utilização, assim, podem ser modificados visando adquirir estabilidade, melhorar as características reológicas das pastas ou de textura dos géis, entre outros. Objetivou-se avaliar o efeito da modificação química (oxidação) na composição química de amidos de mandioca, assim como, nas propriedades físicas e químicas e no perfil de textura dos géis obtidos a partir deles. Foi realizada uma pesquisa experimental com uma abordagem quantitativa de natureza aplicada e método hipotético dedutivo, de objetivos explicativos e procedimentos experimentais. Três marcas de amidos comerciais foram avaliadas, sendo selecionada uma delas para posterior modificação. Foram utilizadas as modificações por permanganato de potássio, hipoclorito de sódio ou ácido cítrico. Os amidos (nativos ou modificados) foram submetidos às análises de composição química, enquanto os géis (3 e 5%) foram avaliados quanto ao perfil de textura (firmeza, coesividade, resiliência, adesividade, gomosidade e elasticidade) e as propriedades físicas e químicas dos géis obtidos a partir deles. Uma marca de amido nativo comercial foi considerada mais apropriada para a modificação química por possuir menor conteúdo de amilose e resultar em géis com parâmetros de textura intermediários. Foi realizada uma análise exploratória dos resultados. A modificação de amidos por oxidação com ácido cítrico ou hipoclorito de sódio resultou em géis com menor firmeza, gomosidade e adesividade e maior claridade, coesividade, resiliência e elasticidade do que os amidos nativos. Além disso, o valor nutricional do amido não foi alterado pela modificação química. O amido modificado com permanganato de potássio originou géis com características físicas, químicas e de textura adequadas, mas apresentou coloração demasiadamente escura, o que limita a sua utilização em alimentos processados. Recomenda-se o uso de amidos modificados por oxidação em coberturas de alimentos, molhos para salada, maionese, como agentes ligantes em produtos de confeitaria ou como emulsificantes.

The Brazilian market for food products with low lactose content and foods for the vegan population, lactose intolerant and even the public that seeks lactose-free food by preference needs diversification. This review sought to describe articles that addressed the development and characterization of non-dairy based desserts. A search was made for references in the CAPES, Lilacs, Scielo, and ScienceDirect databases in September 2019 covering the period 2010-2020 and using the descriptive terms "Frozen desserts " or "Dairy alternatives " or "N on dairy "Or" Ice cream ". As selection criteria, research articles in English and Portuguese involving non-dairy desserts were used. The search allowed the identification of 5 articles that met the established criteria. Although the use of cow's milk substitutes has been explored by the dessert industry, there is still much to explore about the alternatives available to innovate in the design of non-dairy based desserts, so a review on the subject is extremely interesting.

This study aimed to promote improvements through the implementation of a combination of quality tools (checklists, brainstorming, Ishikawa diagram, flowchart, program 5S, 5W1H, PDCA, training, and Good Manufacturing Practices (GMP) in a small pasta industry in Maringá - Paraná, Brazil. The industry is located in the Northwest of Paraná, Brazil, and has a processing capacity of 5000 units of “salgados" per hour. The implementation of the quality tools was carried out according to the stages of the PDCA cycle (plan, do, action, and check). The effectiveness of the measures adopted was measured by comparing the total percentages of conformities and non-conformities before and after the implementation of the tools. The results showed improvements in the processes and products of the industry, due to the significant increase in compliance to 79,04 %, while before the implementation of the tools it was 56,94%. Therefore, the results indicated that the implementation of quality tools provided improvements, as it impacted the increase in compliance with the requirements required by the legislation (RDC 275 from ANVISA), as well as changed the general organization and quality of the industry.
