OBJECTIVE We compared the effects of different kinds of bread fermentation on mineral bioavailability. METHODS Wistar rats were fed one of the following experimental diets for 21 d: control, reconstituted whole wheat flour (white flour plus bran), yeast bread, and sourdough bread. The apparent mineral absorption and intestinal fermentation were measured in each animal. RESULTS Phytate conte...

The laser air-puff method was investigated for non-destructive firmness measurements on kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson cv. Hayward) and apricot (Prunus armeniaca L. cv. CluthaGold). The method involves delivering a sharp puff of air onto a stationary fruit whilst recording the resulting surface deformation with a laser displacement sensor. At a 65-kPa maxi...

Xylanases (EC 3.2.1.8) are hydrolytic enzymes, which randomly cleave the β-1,4-linked xylose residues from xylan. The synthetic gene xynBS27 from Streptomyces sp. S27 was successfully cloned and expressed in Pichia pastoris. The full-length gene consists of 729 bp and encodes 243 amino acids including 51 residues of a putative signal peptide. This enzyme was purified in two steps and was shown ...

Hydrocolloids, often called gums that generally contain many hydroxyl groups and may be polyelectrolytes .Foams are colloidal systems in which tiny air bubbles are dispersed in an aqueous continuous phase. Many processed foods consumed daily are liquid or solid foams, such as the head of soft drinks and beer, whipped cream, mousses, meringue, bread and ice cream. The utilization of these gums d...

BACKGROUND Many children do not eat enough whole grains, which may have negative health consequences. Intervention research is increasingly focusing on nudging as a way to influence food choices by affecting unconscious behavioural processes. The aim of this field study was to examine whether the shape of bread rolls is able to shift children's bread choices from white to whole wheat during bre...

Title:Effects of whole grain rye crisp bread for breakfast on appetite and energy intake in a subsequent meal: two randomized controlled trails with different amounts of test foods and breakfast energy content Authors: Tina Forsberg ([email protected]) Per Åman ([email protected]) Rikard Landberg ([email protected]) Please find attached the revised version of our paper entitled " Effects ...

Rye (Secale cereale L.) is one of the most important bread grains in colder parts of Europe and its importance has been rising recently. The chemical composition of rye grain promises health benefits and it contributes to higher intake of dietary fibre. Conversely, rye baking performance is not as good as required. The baking quality is mainly affected by the activity of amylases measured as Ha...

The aim of this study was to assess the effect of soy flour on nutritional, physicochemical, and sensory characteristics of gluten-free (GF) bread. In this study, corn flour was replaced with soy flour at different levels 5%, 10%, and 15% to produce a more nutritionally balanced GF bread. Physical and chemical properties, sensory evaluation and crust and crumb color were measured in bread sampl...

OBJECTIVE Bread is the largest contributor of Na to the American diet and excess Na consumption contributes to premature death and disability. We sought to determine the Na level at which consumers could detect a difference between reduced-Na bread and bread with typical Na content, and to determine if consumer sensory acceptability and purchase intent differed between reduced-Na bread and brea...

Plots of 19 clones of strawberry (Fragaria ×ananassa Duch.) were planted in 1996. Fruit of 16 clones were harvested in 1997 and fruit of 11 of the same clones plus three additional clones in 1998. Individual plots were harvested on three or four dates in 1997 and from three to seven dates in 1998. Fruit firmness was determined with a penetrometer at harvest, and additional samples were processe...
