Characterization of physicochemical composition, microbiology, sensory evaluation and microscopical attributes of sweetened condensed milk Ciênc. Tecnol. Aliment.
RENHE,Ísis Rodrigues Toledo; PEREIRA,Danielle Braga Chelini; SÁ,Jaqueline Flaviana Oliveira de; SANTOS,Marcelo Cerqueira dos; TEODORO,Vanessa Aglaê Martins; MAGALHÃES,Fernando Antônio Resplande; PERRONE,Ítalo Tuler; SILVA,Paulo Henrique Fonseca da.
Abstract An analysis of nine sweetened condensed milk brands allowed for the identification of statistically significant difference in moisture, water activity (aw), soluble solids, percentage of protein, lactose crystals size, viscosity and in sensorial attributes of texture, characteristic flavor and flour texture. Relevant correlations between the composition and sensorial attributes were determined. Eighty percent of the samples presented of yeast from <0.6 logCFU.g-1 to 4.7 logCFU.g-1 and seventy percent presented of coagulase-negative staphylococcus from <3.1 log CFU.g-1 to 5.7 log CFU.g-1. These results attest the demand for more controls and investments to provide the market with a safe and standardized product.

Optimization of ultrasound-assisted extraction of phenolic compounds from jussara (Euterpe edulis M.) and blueberry (Vaccinium myrtillus) fruits Ciênc. Tecnol. Aliment.
ROCHA,Juliana de Cássia Gomes; PROCÓPIO,Fernanda Ramalho; MENDONÇA,Adriana Corrêa; VIEIRA,Luciana Marques; PERRONE,Ítalo Tuler; BARROS,Frederico Augusto Ribeiro de; STRINGHETA,Paulo Cesar.
Abstract This study was aimed at optimizing the ultrasound-assisted extraction (UAE) of phenolic compounds from jussara and blueberry fruits using the response surface methodology (RSM). UAE was found to be more efficient to extract phenolic compounds from both fruits than the conventional extraction. The optimum extraction conditions for the jussara fruits were: extraction time between 30 and 62 min for total anthocyanins and total phenolics, fruit:solvent ratio of 10% and 6% (w/v) for total anthocyanins and total phenolics, respectively. The ethanol concentration was non-significant (p> 0.05). Acidified water was found to be an extracting solvent as efficient as ethanol in the extraction of phenolic compounds from jussara fruits. The optimum...

Evolution of soluble solid content and evaporation rate curves during the manufacture of dulce de leche (dl) Ciênc. Tecnol. Aliment.
FRANCISQUINI,Júlia d’Almeida; PEREIRA,João Pablo Fortes; PINTO,Michele da Silva; CARVALHO,Antônio Fernandes; PERRONE,Ítalo Tuler; SILVA,Paulo Henrique da Fonseca da.
Abstract Dulce de leche is an evaporated dairy product that can be manufactured in different types of pots or pans. The manufacturing endpoint for dulce de leche can be determined by measuring the soluble solids content. We investigated the evaporation rates and the evaporative capacity of atmospheric pressure evaporators (pans) during the manufacture of dulce de leche. During manufacturing, four different formulations were subjected to soluble solids content determination by refractometry. In addition, the mass balance was used to determine the yield and evaporation rate. A low coefficient of variation and amplitude was found for soluble solids content, indicating standardization and uniformity during fabrication. We also observed a gradual increase in...

Calcium partition in Minas Padrão cheese and its bioaccessibility during ripening time Ciênc. Tecnol. Aliment.
PEREIRA,João Pablo Fortes; MAGESTE,Ana Carolina; CAMPOS,Náira da Silva; SOUSA,Rafael Arromba de; FRANCISQUINI,Júlia d’Almeida; PERRONE,Ítalo Tuler; CARVALHO,Antônio Fernandes de; NUNES,Renato Moreira; MARTINS,Marta Fonseca; SILVA,Paulo Henrique da Fonseca da.
Abstract Nutritionally, cheese and other dairy products have been highlighted especially as a calcium source. Access to minerals is dependent on variables related to diet, lifestyle, and also the health status. This study aimed to evaluate the bioaccessibility and calcium partition in Minas Padrão cheese over its ripening period for experimentally obtained samples. The cheese of the study has been manufactured using two different technologies (A and B). Also to evaluate the evolution of pH over cheese ripening and the influence of calcium partitions in its bioaccessibility along the cheese ripening period. The mean values found for total calcium content were (549 mg⋅100 g-1 – A and 644 mg⋅100 g-1 – B). For calcium in the aqueous phase on average 460 mg⋅100...
