Food Extract of Purple Yam (Dioscorea trifida L.f.) from Brazil: Optimization o...

Purple yam (Dioscorea trifida) has high agricultural productivity in the Amazon region but has not been much investigated. Multivariate strategies were employed to optimize the method to obtain a food extract rich in functional compounds. The optimal conditions showed that the combination of 0.2 g of dried purple yam with 15 mL of citric acid (1%) under agitation in a water bath at 36 °C for 4 min yields an ext...

Red Jambo Flower (Syzygium malaccense L.) as a Potential Bioactive Compound to ...

This paper aimed to demonstrate the production of edible extracts from red jambo flowers, cultivated in northeastern Brazil, and investigate their bioactive properties. For this purpose, a multivariate optimization of the extraction process was performed, by solid-liquid extraction, where it was observed that the presence of ethanol, acetone, and polysorbate in the extracting solution had the most significant i...

A green method for anthocyanin extraction from Clitoria ternatea flowers cultiv...

This study aimed to develop a green method to obtain an anthocyanin-rich edible extract of Clitoria ternatea flowers grown in southern Brazil. The extract was characterized by UHPLC-MSn and analyzed for toxicological potential in an in vivo model, total phenolic content, and biological activities. By using a 23 multivariate design to study the effects of temperature, acidified solvent, and time on the total ant...

Microbiological testing for the proper assessment of the hygiene status of beef...

Microbiological testing is an important quality management tool in the food industry. In this study, the hygiene status of beef carcasses sampled in eight Brazilian slaughterhouses was assessed by enumeration of different hygiene indicator microorganisms, and a model to establish potential associations among these counts was proposed. The carcasses (n = 464) were surface sampled at four slaughtering steps (step...

In total, 159 samples of raw and processed foods of animal origin were co...

Multivariate optimization of Staphylococcus xylosus AD1 biomass production usin...

Staphylococcus xylosus is a microorganism that has important physiological and technological characteristics that make it suitable for use as a starter culture in fermented meat products. For the development of these products in the food industry, it is necessary to produce biomass by the multiplication of starter cultures using low-cost media. This study developed a culture medium based on sugarcane molasses (...

Avaliação da multiplicação de Listeria monocytogenes e da atividade antimicrobi...

Avaliou-se a multiplicação de Listeria monocytogenes em nata, um derivado lácteo com alto teor de gordura, bem como a atividade antilisteria do Biomax D® neste alimento. A atividade antilisteria do Biomax foi comparada com a da nisina. Foram utilizados seis tratamentos: T1: nata + 102 UFC.g-1 de L. monocytogenes; T2: nata + 102UFC.g-1 de L. monocytogenes + 2,5ppm de nisina; T3: nata + 102 UFC.g-1 de L. monocyto...
