In order to ensure the nutritional quality of leafy vegetables produced under intensive cultivation systems, the proximate composition, mineral profile, and trypsin-inhibitory activity of three priority West African vegetable species (Amaranthus cruentus, Ocimum gratissimum, and Solanum macrocarpon) produced with urea micro-doses (20, 40, and 60 kg/ha) were compared with control leaves raised without...
The phenolic compound profile and antioxidant potential of the false flax (Camelina sativa L.) plant, harvested at five morphological stages, that is, from the vegetative to the ripe seed-pod stage, have been investigated. False flax extracts were prepared using 80% (v/v) methanol, and the total phenolic content (TPC), the contents of the individual phenolics and antioxidant activity, measured as...
The aim of this study was to evaluate the impact of the macerating enzyme addition (Sihazym Extro and Vinozym Vintage) on the extraction of phenolics, colour components, and antioxidants in Babica wine. Spectrophotometry was used for determination of total phenolics, anthocyanins, and wine colour parameters (intensity, hue, and chromatic structure); the individual phenolics were detected using HPLC;...
Different maize (Zea mays L.) varieties have been used for thousands of years as a healthy food source in Mesoamerica including pigmented maize. Maize ingestion could contribute to the reduction in the rate of non-communicable diseases and, in turn, to its function as an adjuvant in their management. These diseases are mainly associated with oxidative stress, which is characterized by a redox cell...
The aim of this study was to employ a hybrid approach combined with a fragmentomic idea of research used to analyze bovine milk protein hydrolysates as a source of peptides with a potential bitter taste. Firstly, selected sequences of bovine milk proteins were in silico hydrolyzed using bromelain, ficin, papain, and proteinase K. Hydrolysis was simulated using the BIOPEP-UWM “Enzyme(s) action” tool...
The objective of this study was to assess the suitability of buckwheat grain for agricultural distillate production. The effects of the method of starch liberation on the physicochemical composition of the prepared mashes, fermentation results, the concentration of volatile compounds in the obtained distillates, and their organoleptic features, were investigated. The raw materials used were two cultivars...
The overgrowth of spoilage and pathogenic bacteria may pose risk to consumers health and cause technological and economic losses. Hence, interactions among S. aureus 2064 and E. coli BR in dependence of incubation temperature and different initial counts of both microorganisms were quantitatively described based on cultivation experiments and predictive models. Statistically insignificant differences...
The possible use of high voltage electrical discharges (HVED) at different frequencies (20, 50, and 100 Hz) and ultrasound-assisted extraction (UAE) at different temperatures (20, 40, and 80°C) for the recovery of phenolics from indigenous fungus-resistant grape by-product was evaluated. All extractions were performed over the period of 5, 10, and 15 min and with methanol- and ethanol-based solvents...
The aim of this research was to examine the technological properties of beef emulsions in which fatty tissue was partially substituted with pumpkin seed oil (PSO) encapsulated in alginate or pectin matrix, and where phosphates (F treatments) were simultaneously substituted with shell powder (C treatments). Fat replacement (in the amount of 25%) mostly had no significant influence on pH, cooking loss,...
Coastal and mountainous honey samples were collected from different regions in Jijel (Algeria) to evaluate their moisture content, electrical conductivity, ash content, pH, acidity, protein content, color parameters, antioxidants content, radical scavenging activity, reducing power, and antibacterial activity, to reveal the differences between coastal and mountain honeys and to determine the correlation...
