Article
Isabel grape (IG) products have high contents of phenolic compounds and fiber recognized for their positive impacts on microorganisms associated with health benefits to host. This study evaluated the effects of goat yogurts formulated with ingredients from IG integral valorization on the growth and metabolism of different probiotic strains, as well...

Fish viscera are usually discarded as waste, causing environmental problems, or as low-value by-products. This study describes a self-sufficient and zero waste approach to obtain enzymes and protein hydrolysates from fish by-products. Firstly, recovery steps of viscera enzymatic extract were applied, and the resulting raw extract was stable at a pH...
Article
This study evaluated the effects of a fiber and phenolic‐rich flour (IGF) prepared from Isabel grape by‐products on the growth and metabolism of different probiotics and distinct bacterial populations part of the human intestinal microbiota during an in vitro colonic fermentation. IGF was submitted to simulated gastrointestinal digestion before use...
Chapter
Polyphenols are secondary metabolites of plants, and one of the most important phytochemicals found in herb plants, vegetables, and fruits. In recent years, these compounds have attracted increased attention due to the potential health benefits of dietary plant polyphenols as antioxidants. Epidemiological studies have noted the lower risk of chroni...

... GP contains minerals of which potassium, phosphorus, calcium and iron are the most abundant. However, the increase in the content of ash and lipids may be related to the growth of the fungus, as the cell wall of fungi contains both lipids and inorganic components and the ash content of fungi varies depending on the fungal species and growth conditions [48][49][50]. ...
... Of the enzymes available, proteases, lipases and glutaminases are commonly utilized industrially. Borges et al., [143] describes successful use of proteolytic enzymes extracted from viscera of fish to hydrolyze fish proteins generating comparable results with alcalase ® , though the antihypertensive potential of fish enzyme hydrolysate was less. The viscera could be a useful source of proteolytic enzymes for the detergent industries where high specific activity is a low requirement, and multiple effects of combined enzyme extracts may carry advantages. ...
... Silva et al. reported that goat yogurt formulated with fiber-and phenolic-rich ingredients from the integ-ral valorization of Isabel grape had a positive effect on gut microbiota and human health [22]. Our findings were consistent with the results obtained by Fuhrman et al., who determined total phenolic and anthocyanin contents in red and white grape varieties during storage [23]. ...
... Over the past decade, there has been an increase in the number of publications studying the effect of polyphenols on diabetes. All classes of phenolic compounds have shown antidiabetic potential [64]. The research suggests that the primary mechanism of action is associated with inhibiting glucose absorption by inhibiting digestive enzymes such as α-glucosidase and α-amylase [7,65,66]. ...
... Bordiga et al. [30] assessed the potential prebiotic activity toward L. plantarum (P17630) and L. acidophilus (P18806) of different oligosaccharidic fractions obtained before and after distillation of grape seed pomace and they claimed that oligosaccharidic fractions improved the growth of L. acidophilus (P18806) during in vitro fermentation. Silva et al. [57] evaluated the stimulatory effects of a flour produced from Isabel grape by-products (peels and seeds) on the growth and metabolism of different probiotic strains and bacterial populations of the intestinal microbiota during an in vitro colonic fermentation. The by-product flour showed stimulatory effects on probiotics causing increased viable counts, decreased pH values, and stimulated the increase of the population of beneficial microorganisms, accompanied by the production of lactic acid and short-chain fatty acids. ...
