The biological values of the proteins of pea meal, rye bread (baked from 70 % rye flour by the Municipal Bakeries in Warsaw), of two mixtures of wheat rolls and pea meal and of two mixtures of rye bread and pea meal have been determined by the method of Osborne et al. [1919]. The bread was dried at 350 and the dry product ground in a mill. The peas were boiled, dried and ground. The following m...

In the developing endosperm of bread wheat (Triticum aestivum), seed storage proteins are produced on the rough endoplasmic reticulum (ER) and transported to protein bodies, specialized vacuoles for the storage of protein. The functionally important gluten proteins of wheat are transported by two distinct routes to the protein bodies where they are stored: vesicles that bud directly off the ER ...

The complex gene expression mechanisms that occur in plant mitochondria, such as RNA editing and splicing, are not yet well understood. RNA editing in higher plant mitochondria is a highly specific process which modifies mRNA sequences by C-to-U conversions. It has been suggested that in some cases this process is required for splicing. Here, we use an experimental model based on the introducti...

The content of free and bound phenolics their antioxidant capacity in cookies enriched by nettle seed flour a phenolic extract, before, during after thermal processing (baking at 180°C for 25 min) were examined. results compare these properties to cookie obtained only from wheat flour, as the control. Better incorporating than extract. During processing, different changes (increase, decrease or...

Cereal Chem. 90(3):240–248 Arabinoxylans (AX), xylanase, and xylanase inhibitors have an important role in many cereal food processing applications. The effects of genotype, growing location, and their interaction (G × L) on AX, apparent xylanase activity, and apparent xylanase inhibition activity of Triticum aestivum xylanase inhibitor (TAXI) and xylanase inhibiting protein (XIP) were investig...

Abstract In the present study we examined effect of presence wheat bugs ( Eurygaster spp. and Aelia spp.) on mortality, progeny production infestation patterns three stored product insects, Trogoderma granarium Everts, Sitophilus oryzae (L.) Rhyzopertha dominica (F.). The bioassays were carried out under laboratory conditions (25 ± 1 °C, 60 5% relative humidity (r.h.) continuous darkness), 20 a...

Lignocellulosic residues (wheat straw, corncobs, and cornstalks) were treated with a dilute alkaline solution of hydrogen peroxide and suspended in cattle rumen in situ to measure microbial degradation. The rate and extent of dry matter disappearance were markedly increased as a result of the treatment. Results in vivo indicate that this treatment increases the fermentability of wheat straw str...

Grading factors associated with adverse growing conditions in Canada and the United States affect the edibility and end-use performance of common wheat. Mycotoxins are associated with fungal infections like fusarium head blight and ergot. Mycotoxins partition themselves among wheat milling products, and are relatively stable throughout wheat end-use processing. Fusarium head blight also has adv...
