- Cereals are a fundamental part of the world diet; therefore, their adaptation in different environments due to climate change should be achieved. Studying the modifications that may occur during plant development is essential, as well as in the quality of the harvested product. Thus the objective of this research is to analyze the effect of water stress on development, growth, production, and agronomic quality of rye crop and harvested grain. For sowing, a completely randomized one-way experimental design was used, where the treatments consisted of three different soil moisture regimes. The variables evaluated at the time of harvest were plant height and number of spikes per linear meter. After harvest, the variables evaluated were spike size and the number of grains it contained, as well as size and color of the grain, weight of 1000 grains, test weight, yield, ash and protein content. An analysis of variance and Tukey’s comparison of means test (P < 0.05) were performed for ash and protein content, and Duncan (P < 0.05 and P ≤ 0.0001) for the rest of the determinations. The results showed that less irrigation did not negatively affect the crop with an appropriate agronomic development, highlighting an increase in the number and size of spikes, an increase in the number of grains per spike, as well as a high yield and protein content of the grain. These values were higher than those reported in previous research, which confirms that even though rye is considered a winter cereal, it managed to acclimate to soil conditions, decreased water, and high temperatures in the coastal area of Hermosillo, Sonora, México.

- Wheat flour and cane sugar were partially substituted (50 and 75%) by a mango-processing by-product (MPB) as an added-value food ingredient in muffins. Their sensory analysis, chemical composition, antioxidant activity and in vitro starch hydrolysis properties were studied. Sensory analysis showed statistically significant difference (p < 0.05) between control and muffins 75% MPB substituted level (p < 0.05) with the highest score. Proximate analysis revealed that muffins substituted with MPB had significantly (p < 0.05) higher moisture, ash, soluble, insoluble and total indigestible fraction contents but lower total soluble carbohydrates and available starch contents than a non-substituted (control) muffin. Total soluble polyphenol (TSP) content increased about three times (from 1.86 to 5.36 g GAE/100 g dw) with MPB substitution. Chlorogenic, caffeic, gallic, hydroxycinnamic and ferulic acids were identified as major TSP. Muffins with MPB, exhibited better antioxidant properties (104.0 to 108.5 mu mol TE/g dw for DPPH assay and 34.1 to 19.1 mmol TE/g dw for FRAP assay) than the control formulation. The presence of high phenolic and insoluble indigestible fraction contents, which may be responsible of the lower rate of starch hydrolysis observed in muffins prepared with MPB, might modulate the postprandial glucose response in vivo. MPB may be used as an ingredient in foods with add-value with potential health-promoting features, besides providing a solution to the environmental problems associated with the disposal of mango by-products.
