Summary: Colombian purple corn Zea mays L. by-products were chemically characterized after purification and fractionation. Cob and leaves showed a more complete flavonoid profile with higher content of anthocyanins and flavonols compared to grains, resulting in the highest reducing power and radical scavenging activity. The antioxidant fractions corresponded to higher molecular weight compounds. This study provides the first chemical and antioxidant characterization of purple corn by-products, as well as pure fractions of Zea mays L. for various industries.

Summary: Corn is the most economically important crop globally, but in Mexico, the use of tillage methods, monoculture, and excessive synthetic agrochemicals has led to fertility and yield loss. Alternative fertilization methods using chemical fertilizer, organic matter, and biofertilizer can enhance corn plant defense systems and increase yield. In this study, different fertilization schemes were tested on purple corn plants, and significant differences in growth, yield, and chemical characteristics of the corn grain were observed. Treatment T7 showed the best grain yield, protein content, and starch quality. Adequate macro and micronutrient contributions were found to positively affect corn crops in the fertilization schemes studied.

Summary: In this study, a large-scale chemical characterization of corn silk extracts was conducted, and chemometrics was used to identify potential candidate metabolites for antioxidant and anti-glioma activities. The results indicate that two flavone glycosides and one O-methylated anthocyanidin are likely the main contributors to the biological activities of the corn silk extracts.

Summary: The study found that the phenolic and flavonoid contents in different genotypes of sweet corn kernels increased from 10 to 30 days after pollination, with higher levels in the YT28 genotype possibly due to higher expression of the CHS gene. Sweet corn has competitive phenolic contents, antioxidant capacities, and antiproliferative abilities, with its bioactive potential and nutritional value increasing during the maturation process.

Summary: Tea cultivars with purple shoots have drawn global attention. A study comparing purple-coloured tea leaves with green-coloured tea leaves found differences in anthocyanins, flavonoids, and other compounds, with the former containing higher levels of certain compounds. This suggests that modified anthocyanins and co-pigmented flavonoids are primarily responsible for the purple colouration of the tea leaves.

Summary: This study investigates the within-field spatial distribution and factors associated with the abundance of Dalbulus maidis, the primary pest in cornfields. The results show that infestations of D. maidis are higher at the boundaries of the central pivot, indicating an edge-biased distribution. The ranges vary and the spatial dependency is strong to moderate. Air temperature has a positive effect on the population of D. maidis, while rainfall has a negative effect.

Summary: Intercropping high value forage cover crops with wider corn rows can improve crop productivity and offset economic losses caused by grain reductions. Economic analysis showed that high yielding, quality forage crops can offset up to 12.6% of economic losses. Further research is needed to refine and optimize this intercropping system for farm use.

Summary: In this study, four polythiourethane films with different types of polyols and isocyanates were synthesized, characterized, and foamed. The results showed that the type of isocyanate greatly influenced the crystallinity and stiffness of the polymers, while the type of polyol modified the FT-IR spectra and the decomposition curve of the material with temperature. Furthermore, the choice of isocyanate also affected the properties of the foams obtained from the polymeric material.

Summary: This study experimentally assessed the hydrodynamic characteristics of supercritical-pressure R134a in a horizontal circular tube. It was found that the hydrodynamic characteristic curve of R134a under supercritical pressure does not have a negative-slope region but a transition region. The transition region becomes more evident with increasing heat flux, while it weakens with increasing pressure and inlet temperature. Moreover, the onset of the transition region shifts in the direction of high mass flow rate with increasing heat flux.

Summary: This research aimed to valorize brewery spent grain (BSG) using subcritical water hydrolysis (SWH) modified by six different natural deep eutectic solvents (DES) and determining their bipotentialities. The findings showed that BSG hydrolysates obtained through DES-induced SWH contained high levels of sugars, proteins, flavonoids, phenolic compounds, and essential amino acids. The hydrolysates also demonstrated antimicrobial activities, and the presence of bioactive compounds was confirmed through FT-IR analysis. This comprehensive profiling of bioactive compounds from BSG using DES-mediated SWH can contribute to the efficient valorization of BSG for industrial purposes.
