Pequi oil presents high levels of unsaturated fatty acids and beta-carotene has been used for nutraceutical purposes. Microcapsules can improve the protection bioactive compounds in pequi mask inherent smell taste food applications. However, stability microencapsulated its influence on product characteristics need to be investigated. This work evaluated impact microcapsules physicochemical ferm...

In this study, we evaluated vitamin D and mineral (iron, zinc, magnesium) transfer to the bolus aqueous phase during digestion of meals with/without pulses. We performed in vitro digestions using test made either i) beef and/or semolina chickpeas, or ii) potatoes supplemented not with fibers, phytates, tannins saponins. Chickpea presence led a decrease bioaccessibility (?56%, p ? 0.05) solubili...

Persimmon which is widely known as “Trabzon Hurması” and “Cennet Meyvesi” a very popular fruit with bright orange color. In the presented study, extractable, non-extractable, total phenolic content (TPC), antioxidant capacity (AC) bioaccessibility of Trabzon persimmons (astringent, non-astringent wild persimmon) were determined. The results this study indicated that all types have great importa...

Aquatic weeds are widely used as animal feed in developing countries. However, information about element bioavailability from these plants is lacking. A combination of an in vitro method [physiologically based extraction test (PBET)] and an in vivo feeding trial was used in this study to investigate potential element bioaccessibility and estimated bioavailability of Pistia stratiotes (PS). Cu, ...

Previous studies have provided evidence that the physical encapsulation of intracellular nutrients by cell walls of plant foods (i.e. dietary fibre) plays a predominant role in influencing macronutrient bioaccessibility (release) from plant foods during human digestion. One unexplored aspect of this is the extent to which digestive enzymes can pass through the cell-wall barrier and hydrolyse th...

Antioxidants are abundant compounds primarily found in fresh fruits and vegetables, and evidence for their role in the prevention of degenerative diseases is continuously emerging. However, the bioaccessibility and bioavailability of each compound differs greatly, and the most abundant antioxidants in ingested fruit are not necessarily those leading to the highest concentrations of active metab...

Arsenic (As) speciation and distribution are two important factors in assessing human health risk from As-contaminated soil. In this study, we used the combination of physiologically based extraction test (PBET) and Simulator of Human Intestinal Microbial Ecosystem (SHIME) to determine soil As metabolism by human gut microbiota. The results showed that the percentage of soil arsenate [As(V)] tr...

Bioaccessibility of trace metals originating from urban particulate matter was assessed in a worst case scenario to evaluate the uptake and thus the hazardous potential of these metals via gastric juice. Sampling was performed over a period of about two months at the Getreidemarkt in downtown Vienna. Concentrations of the assayed trace metals (Ti, Cr, Mn, Co, Ni, Cu, Zn, Mo, Ag, Cd, Sn, Sb, Tl ...

Cherry laurel is a less known fruit species with an astringent taste and mostly consumed as fresh only in the Black Sea Marmara regions of Turkey. (Laurocerasus officinalis Roemer) leaves can be prepared different forms such infusion by steeping dried leaf boiled water extract for its further use food supplement or ingredient. In thisstudy, aqueous ethanol extracts cherry were examined terms to...
