Whether it's a fragrant slice of freshly baked artisan bread or a perfectly prepared pasta entree, most of us eat foods made from wheat flour every day. The quality of that flour is due, in large part, to the work of hundreds of different proteins that perform specialized tasks inside the wheat kernel, or grain.

Discovering more about the work of these proteins--and how they're affected by the heat, soil nutrients, and other environmental conditions in which the plant is...

Apricot Kernel: Physical and Chemical Properties
JAOCS, Journal of the American Oil Chemists' Society ; Sir: The apricot, Prunus armeniaca L., is a member of the Rosaceae, subfamily Prunoideae. Very few apricot cultivars are grown commercially throughout the world. Instead, cultivars tend to be grown in only one region of a country, and most would be virtually unknown outside of that region. Turkey

Evaluation of novel precast SDS-PAGE gels for separation of sorghum proteins
Cereal Chemistry ; ABSTRACT Precast polyacrylamide gels using novel buffer chemistry for enhanced resolution and shelf life stability of the gels were evaluated for separating sorghum proteins. Two gels with different acrylamide concentrations, 12 and 4-12%, were tested with two different buffer systems. Gels were
Strategies to Prevent Mycotoxin Contamination of Food and Animal Feed: A Review
Critical Reviews in Food Science and Nutrition ; Mycotoxins are fungal secondary metabolites that have been associated with severe toxic effects to vertebrates produced by many important phytopathogenic and food spoilage fungi including Aspergillus, Penicillium, Fusarium, and Alternaria species. The contamination of foods and animal feeds with
Thioredoxin-Linked Proteins Are Reduced during Germination of Medicago truncatula Seeds1[W][OA]
Plant Physiology ; Germination of cereals is accompanied by extensive change in the redox state of seed proteins. Proteins present in oxidized form in dry seeds are converted to the reduced state following imbibition. Thioredoxin (Trx) appears to play a role in this transition in cereals. It is not known, however,
Modeling Grain Nitrogen Accumulation and Protein Composition to Understand the Sink/Source Regulations of Nitrogen Remobilization for Wheat
Plant Physiology ; A functional explanation for the regulation of grain nitrogen (N) accumulation in cereal by environmental and genetic factors remains elusive. Here, new mechanistic hypotheses of grain N accumulation are proposed and tested for wheat (Triticum aestivum). First, we tested experimentally the
Structural, Biological, and Evolutionary Relationships of Plant Food Allergens Sensitizing via the Gastrointestinal Tract
Critical Reviews in Food Science and Nutrition ; The recently completed genome sequence of the model plant species Arabidopsis has been estimated to encode over 25,000 proteins, which, on the basis of their function, can be classified into structural and metabolic (the vast majority of plant proteins), protective proteins, which defend a plant
Effect of Foliar Sulfur and Nitrogen Fertilization on Wheat Storage Protein Composition and Dough Mixing Properties
Cereal Chemistry ; ABSTRACT Nitrogen (N) and sulfur (S) supplies have a strong influence on the quality and quantity of wheat storage proteins, which play an important role in the breadmaking process. Nitrogen derived from urea, S from micronized elemental sulfur, and a mixture of both (N+S) were applied at anthesis
Using Multivariate Techniques to Predict Wheat Flour Dough and Noodle Characteristics from Size-Exclusion HPLC and RVA Data
Cereal Chemistry ; ABSTRACT Flour proteins of hard and soft winter wheats grown in Oregon were characterized by size-exclusion HPLC (SE-HPLC). Flour pasting characteristics were assessed by a Rapid Visco Analyser (RVA). Principle component scores (PCS) were calculated from both RVA data and from absorbance area and %
