They are both characterized by the expression of specific isoforms of α‐amylase in particular genotypes in the grain prior to harvest. The enhanced expression of α‐amylase in both LMA and PHS results in a reduction in Falling Number (FN), a test of gel viscosity, and subsequent downgrading of the grain, alon ...
... To date, research on preharvest sprouted (PHS) wheat has mostly been conducted on kernels germinated under laboratory conditions, which differ widely from conditions in the field. To obtain detailed knowledge of the evolution of hydrolytic enzyme activities in PHS wheat (Triticum aestivum), a broad collection of samples from three varieties was obtained by harvesting before, at, and after maturity ...

Abstract:
... In Poland, in recent years, there has been a great interest in growing spelt wheat. This is dictated not only by an increasing demand for food with higher healthy properties and unique taste, but also by a possibility of attracting farmers’ attention to this cereal as an alternative crop, with smaller requirements regarding the use of fertilization, as compared with common wheat. The aim of this s ...
... Results of ten cycles of divergent selection on water extract viscosity (WEV) based on varieties of winter rye Al’fa and Moskovskaya 12 are presented. Efficiency of selection depended both on genotype of a variety and direction of selection. Selection in a plus-direction was more effective than in a minus-direction. After ten cycles of selection, the potential of WEV increased in high viscosity po ...
... BACKGROUND: The measurement of α‐amylase (EC 3.2.1.1) in sprout‐damaged grains is a crucial analysis yet a problematic one owing to the typically low α‐amylase levels in ground wheat samples. A number of standardised methods such as the Falling Number method and the Ceralpha method exist which are routinely used for the assay of α‐amylase. These methods, however, are either highly substrate‐depend ...
... Previous investigations have suggested waxy (amylose-free) wheats (Triticum aestivum L.) possess weak gluten properties and may not be suitable for commercial gluten extraction. This limitation could prevent the use of waxy wheat as a source of unique starch, because gluten is a by-product of the wheat starch purification process. Fifty waxy wheat lines were used to determine the extent to which g ...
... In this work, the response surface methodology was used to determine the optimum level of input variables, gluten deformation index (mm) and the level of grape seed flour (%) addition in wheat flour that improve falling number index and Mixolab dough rheological parameters. The full factorial model was the best compatible model which fitted to each response. A replacement dose of 4.08% in wheat fl ...
... The current work examines the physicochemical properties of wheat grains after 30, 60, 90, 120, and 150 days of storage. Storage time had a considerable influence on the quality of wheat, which remained stable for up to 90-120 days. Compared with freshly harvested wheat, increased storage time resulted in a decrease in catalase activity. However, damaged starch content, flour yield and gluten inde ...
