“…The ash content gives a rough idea of the total mineral amount present in the maize grain. The laboratory experiments show that maize grains contain ash content in the range of 0.81-1.35% [15]. DFD has higher ash content 1.18 % compared with other treatment methods whereas GHD has shown lower ash content (0.81%), as shown in Table 3.…”

“…The results of percentage crude fiber contents were found in the range of 2.1-3.47%, which is slightly higher than the reported values in the literature. Qamar et al [15] reported that the percentage of crude fiber contents was found in the range of 0.79-2.78%. The crude fiber in maize largely composed of cellulose and hemicellulose provides beneficial effects in humans by a lower risk of several diseases, including cancers some heart diseases, and increasing water retention capacity during the passage of food along the gut.…”

Objectives: This study attempt to investigate the appropriate drying methods for post-harvest storage of maize grains with preserving important quality and physiochemical characteristics. Methods: The maize samples were dried using different drying methods such as field drying, greenhouse drying, solar drying, direct fire drying, hot air drying, and forced air drying. Further, the dried maize grains were analyzed for physical parameters of bulk density, particle density, porosity, specific gravity, shrinkage, and color. The proximate composition of dried maize grains was analyzed for crude protein, fiber, fat content, moisture, and ash content. Results: There were significant differences (p<0.05) observed for bulk density, particle density, porosity, specific gravity, shrinkage, and color between different drying techniques. When considering proximate analysis, protein, moisture, and ash content were shown significant differences (p<0.05) between different drying methods. Whereas, fat and fiber content of samples were not shown a significant difference (p>0.05) for different drying methods. Conclusion: Different drying methods affect the quality and physiochemical properties of maize grains. Among different drying techniques, the forced air oven drying method preserved physiochemical and nutritional properties considerably compared to other drying techniques.

“…La cruza L5 × L1, con el contenido mayor de minerales en el grano (1.85 g 100 g -1 de ms) estuvo formada por dos líneas de baja ACG para esta variable, pero fue la cruza de más alto efecto de s ij , con un valor de 0.32. El efecto y contenido de cenizas más bajo lo presentó la cruza L5 × L3, con -0.54 y 0.70 g 100 g -1 de ms. En comparación con valores de cenizas reportados en la literatura (0.81 g 100 g -1 de ms, Qamar et al, 2016; 1.80 g 100 g -1 de ms, Cázares-Sánchez et al, 2015), algunos genotipos analizados en el presente estudio pueden considerarse como de alto contenido mineral.…”

“…De acuerdo con el tipo de maíz producido en México, el de grano blanco ocupa el primer lugar, al representar 88 % de la producción nacional (SIAP, 2017). Su uso es principalmente para la alimentación humana, aunque de él también pueden obtenerse aceites e insumos para la fabricación de barnices, pinturas, jabones y gomas (Qamar et al, 2016). Referente a su composición, Cázares-Sánchez et al (2015) señalan que en el grano de maíz la cantidad de proteína y aceite no es alta en comparación con la de otros cereales, pero que existe variación entre y dentro de razas o poblaciones, que debe ser aprovechada en los programas de fitomejoramiento.…”

Para proponer el mejor método de mejoramiento genético de una población es indispensable conocer sus parámetros genéticos y la variación genética que en ella existe. El objetivo de este estudio fue identificar los efectos genéticos, así como los posibles efectos maternos que actúan sobre algunos componentes nutrimentales y bioactivos del grano de maíz (Zea mays L.) en cruzas simples formadas a partir de cinco líneas endogámicas S6-S8. Las cruzas fueron desarrolladas para sistemas de producción en condiciones de riego y se evaluaron en Montecillo, Texcoco, Estado de México durante el ciclo de producción primavera-verano 2014. Con el grano de la F1 de las cruzas y de los progenitores se realizó el análisis genético del contenido total de aceite, proteína, almidón, cenizas y ácido fítico. Los resultados mostraron mayor variación para la aptitud combinatoria específica (ACE) que para la aptitud combinatoria general (ACG) en cada uno de los componentes nutrimentales; la ACE y ACG representaron, en promedio, 53 y 12 %, respectivamente, de la variación entre los genotipos, por lo que los efectos genéticos no aditivos (dominancia y epistasis) prevalecieron sobre los aditivos (ACG) entre los genotipos evaluados. Los efectos maternos y recíprocos mostraron diferencias significativas (P ≤ 0.01) para todas las variables, excepto para contenido de almidón. Se definió el comportamiento de los progenitores y de sus cruzas para dirigir el aprovechamiento eficiente de las características evaluadas. Algunas cruzas fueron superiores a sus progenitores en el contenido de los componentes bioquímicos, pero es necesario considerar la dirección del cruzamiento, dados los efectos maternos significativos encontrados en los componentes del grano.

“…Worldwide, maize ( Zea mays L.) is the most produced cereal crop and it is considered one of the most important cereals for human consumption and animal fodder (Qamar, Aslam, & Javed, 2016; Rocha‐Villarreal, Hoffmann, Levien‐Vanier, Serna‐Saldivar, & García‐Lara, 2018). In Mexico, it is the most consumed cereal, and the “tortilla” is the common form of consumption (Vazquez‐Carrillo, Santiago‐Ramos, Gaytan‐Martínez, Morales‐Sanchez, & Guerrero‐Herrera, 2015).…”

Mineral and fatty acid contents of maize kernels with different levels of polyembryony

et al. 2020

View full text Add to dashboard Cite

Background and objectives Maize (Zea mays) is a cereal of great commercial importance around the world. It has been reported that maize presents polyembryony (PE), which is described as the appearance of two or more seedlings from a germinated seed. Minerals and fatty acids (FA) play important roles in the growth and development of plants and animals. The objective of this work was to determine the minerals and FA content in embryo and endosperm of 32 maize genotypes kernels with different levels of PE (high [NAP], low [NBP], and nonpolyembryonic [T]). Findings The polyembryonic genotypes showed higher concentrations of calcium, magnesium, phosphorous, and potassium. In this study, magnesium was only found in the embryo, while in the embryo of NAP genotypes were found the highest content of K (1,834 mg/kg) and P (656 mg/kg). In contrast, the highest amount of Mg (216 mg/kg) was found in the embryo of NBP genotypes. On the other hand, the highest Ca (251 mg/kg) content was found in the endosperm of NAP genotypes. The highest oil content was observed in NBP‐9‐EM genotype grains with 50.2%, while the highest percentage of oleic (29.10%) and linoleic acid (63.21%) was found in kernels of the NAP‐6‐EM genotype. Conclusions The polyembryonic maize has high mineral content, and some of them have been associated with the human diet; in addition, in these genotypes, high oil content (with the presence of essential FA) was observed. Significance and novelty These results are important because polyembryonic maize kernel may be an alternative for adequate nutrient and essential oils intake. In addition, to the better agronomic characteristics offered by polyembryonic maize genotypes, which may imply a greater income for maize producers.
