Increasing atmospheric CO2 modifies durum wheat grain quality and pasta cooking quality

The present study focused on the quality traits of durum wheat grains (protein and content, gluten content, yellow pigment content), semolina (gluten index and yellow index) and pasta (firmness, yellow index, cooking time) obtained from 12 durum wheat genotypes grown under elevated atmospheric CO₂ concentration in an open field Free Air CO₂ Enrichment (FACE) experiment. The aims were to evaluate the impact of elevated CO₂ on durum wheat pasta making related traits as well as investigate genetic differences existing in a panel of old and modern cultivars. The protein content showed a not significant decrease (7%), the GC decreased significantly (13.3%), while the GI showed an increasing significant tendency (14%). The overall pasta quality (firmness and weight) worsened in ELE. Correlation between all traits and pasta firmness demonstrated that the decrease in pasta firmness under ELE was correlated with GPC and GC while it was not with the GI. All varieties, although to different extent, showed lower pasta firmness values compared to the ambient condition. Among the varieties tested, some were more sensitive than others to the increased atmospheric CO₂ concentration, a finding that can be exploited by breeding for designing novel genotypes with lower sensitivity to increased atmospheric CO₂.

Interrelationships of quality testing methods and relative effectiveness of surfactants on potato flake quality

Correlation was found between several methods which were used to evaluate the relative effectiveness of surfactants in potato flakes. Notably, Amylograph rate of rétrogradation and Amylograph temperature at peak viscosity correlated very well with the level of free starch (Blue Value Index). Overall, calcium and sodium stearoyl-2-lactylate did not perform well in complexing free starch to improve rheological properties unless accompanied by low alpha monoglycerides or distilled monoglycerides.

The nutritional quality of Lupinseed

Mature seeds of four Lupinus species,L. albus, L. angustifolius, L. luteus andL. mutabilis, have been analysed comprehensively to evaluate their potential for nutrition. Particular interest attaches to the comparison betweenlupinus species and soyabeans. All species are rich in high-quality protein, as judged from amino-acid profiles,In vitro studies indicate high levels of digestibility and imply the presence of few interfering factors. In contrast to many other legumes, lupinseeds are free of both protease inhibitors and haemagglutinins. Only one factor, a C-glycosyl poly-hydroxy flavone, which could conceivably interfere with protein absorption, has been identified. Lupinseed could possibly be developed as an oilseed crop, though oil contents are currently somewhat lower than those of soyabeans. The composition of lupinseed oil is similar to that of soyabean oil, both being limited in quality by the presence of linolenic acid. The bright yellow colour of the partially refined oil is due to the presence of the two carotenoids, β-carotene and zeaxanthin. Lupinseed is well-known to contain toxic alkaloids of the quinolizidine group. However, intensive breeding programmes involving all four named species have been in progress for many years. At least in the cases of the first three species, cultivars have been developed that are virtually alkaloid-free. Alkaloid profiles are of interest in being decisive chemotaxonomic indicators of species. The pyrimidine bases responsible for inducing favism through the consumption ofVicia faba are absent from lupinseed. Like soyabeans, lupinseed invariably contains a range of chemically complex saponins. Concentrations in the seed are of a similar order, but it is doubtful whether these should be considered significant anti-nutritional factors for Man. Lupinseeds contain a range of oligosaccharides—raffinose, stachyose and verbascose —which correspond with the flatus factors present in soyabeans and many other legumes. Levels, however, are no higher than those found in soyabeans.
