The present work focuses on developing a model of the duodenum considering motility, biochemical reactions occurring under effects produced by secreted digestive juices, and absorption reaction products in normal conditions case functional disorders. Analysis literature sources allowed identifying basic bile components pancreatic intestinal juice enzymes influencing fats, proteins carbohydrates...

BACKGROUND Vinegars based on fruit juices could conserve part of the health-associated compounds present in the fruits. However, in general very limited knowledge exists on the consequences of vinegar-making on different antioxidant compounds from fruit. In this study vinegars derived from apple and grape are studied. METHODS A number of steps, starting from the fermentation of the fruit juic...

Display of heterologous antigens on the cell surface is considered a useful technique for vaccine delivery by recombinant lactobacilli. In this study, two recombinant Lactobacillus acidophilus derivatives displaying Salmonella flagellin (FliC) were constructed using different anchor motifs. In one instance, the FliC protein was fused to the C-terminal region of a cell envelope proteinase (PrtP)...

Food is the main source of mineral elements but some are also provided with drinking water and supplements. Juices, for example, are an important source of mineral elements. In infants’ diet minerals are provided mainly by fruit and vegetable purée juices. Infants and young children should be given juices labelled as “special purpose food”. Pasteurised juices are recommended for infants, as the...

NEARLY all food niaterials are in too complex and insoluble forms as they are consumed by either animals or man to be absorbed and assimilated. The specific purpose of digestion, therefore, is to convert these food substances into simple and soluble materials fit for absorption and assimilation. All animals except tlie most primitive types are provided with several highly specialized digestive ...

Although the beneficial effects of moderate wine intake are well-known, data on antioxidant capacity of grape juices are scarce and controversial. The purpose of this study was to quantify total polyphenols, anthocyanins, resveratrol, catechin, epicatechin, procyanidins, and ascorbic acid contents in grape juices, and to assess their possible antioxidant activity. Eight Vitis labrusca juices--w...

Botulinus toxin resists a degree of acidity equivalent to that of the stomach even when exposed thereto for 24 hours at 37 degrees C. It is less resistant to alkali, however, as shown by the fact that in a medium of weakly alkaline reaction its potency is reduced to less than one-tenth in 24 hours. It is unaffected by peptic and tryptic digestion. Because of its instability in mildly alkaline s...
