“…This way, not surprisingly the genetic variability found in maize landraces is appreciable, a trait that seems to be well correlated to the chemical diversity found in several types of biomass from the above mentioned cereal [22][23][24]. Indeed, in a previous work, our research group detected a wide range (0.12 to 11.64 g·g ) of carotenoid contents in 26 landrace maize flour types from Anchieta County [21].…”

The carotenoid composition of the silk tissue of Zea mays (L.) has not been investigated despite its large occurrence in maize grains. For the purpose of evaluating maize silk as a source of carotenoids, samples from eight landraces developed and cultivated in Southern Brazil were assayed. The silk samples were harvested from individual plants through the fourth and seventh day after they emerged, frozen in liquid N 2 , and lyophilized. The carotenoids were extracted with a MeOH/toluene solution (1:1, v/v), 30 min, and saponified (15% KOH, 12 h, 40˚C). The RP-HPLC-UVvisible analysis revealed lutein as the main carotenoid (88.75%) in maize silks, with a wide range of contents (dry weight), i.e. 39.11 g·g −1 (Palha Roxa 18) to 176.12 g·g −1 (Língua de Papagaio) among the studied genotypes.Smaller amounts of trans-β-carotene, -carotene, and zeaxanthin were also detected. The results revealed that in parallel to the claimed high genetic variability of maize landraces, a quite variable carotenoidic composition of silk tissue seems to occur in the germoplasm cultivated in Southern Brazil. Taking into account the usage of lutein for the prevention of several pathologies, especially the age related macular degeneration, some maize landraces (e.g. Língua de Papagaio and Rosado) might be interesting sources of a lutein-rich extract that could add value to an underutilized biomass.

“…While silks from some landraces, e.g. Roxo 29 and Roxo 41, have lower potential as a source of lutein, their grains have shown the highest content of carotenoids [21]. Thus, the usage of grain coloration as a parameter for the selection of varieties with high potential as a source of lutein in tissue silks.…”

Effect of different calcium sources on the bioactive compounds stability of extruded and nixtamalized blue maize flours

et al. 2014

The stability of antioxidants in extruded and nixtamalized blue maize flours with calcium hydroxide [Ca(OH) 2 ] and calcium lactate [C 6 H 10 O 6 Ca] were evaluated. Extruded blue maize flours batches were obtained by mixing blue maize flours separately with different Ca(OH) 2 (0.1, 0.2 and 0.3 %) and C 6 H 10 O 6 Ca (0.3, 0.6 and 0.9 %) concentrations respectively and extruded to obtain the extruded flours. For nixtamalized flours, the maize grains were cooked at 1 % Ca(OH) 2 and 2.95 % C 6 H 10 O 6 Ca concentrations respectively. Color, antioxidant activity, total phenolics, total anthocyanins and individual anthocyanins, contents were analyzed. Color, antioxidant activity, anthocyanins contents and total phenolics decreased as the calcium hydroxide concentration increased. In contrast, increasing the calcium lactate concentration on the extruded flours had the opposite effect. The extrusion process retained 57-47 %, 72-62 % and 79-65 % of the anthocyanins content, total phenolic content and antioxidant activity, respectively. These retention rates were higher than those of the nixtamalized flours using the same calcium sources. Cyanidin-3-glucoside and pelargonidin-3-glucoside were identified in the maize kernel and flours. Cyanidin-3-glucoside concentration was increased by both extrusion and nixtamalization processed with either of the two calcium sources. In contrast, pelargonidin-3-glucoside concentration decreased by both processes. Other anthocyanins were observed, but they were not identified.

“…However, studies on variation among genotypes and the effects of environments are scant. Substantial and significant variations in phytochemical content and antioxidant activity were observed between a set of corn genotypes and even among classes of colors, and the potential health benefits provided by corn depended firstly on corn genotypes (Kuhnen et al 2011). Kernel color can be easily identified visually and, therefore, can be increased through phenotypic selection (Rodriguez et al 2013;Shen et al 2009).…”

Genotypic variability in anthocyanins, total phenolics, and antioxidant activity among diverse waxy corn germplasm

et al. 2014

Identification of germplasm sources of waxy corn (Zea mays L. var. ceratina) with high variability for anthocyanins, phenolic compounds, and antioxidant activity is an important phase for waxy corn breeding for improvement of useful phytochemicals. The objectives of this study were to evaluate 49 genotypes of waxy corn for color parameters, monomeric anthocyanin content (MAC) and total phenolic content (TPC), and antioxidant activities. The experiment was conducted under field conditions in a randomized complete block design with three replications for two seasons in the rainy and the dry season 2010. Corn genotypes and seasons were significantly different (P B 0.01) for most traits under study except for TPC. Variations due to genotype were large for all characters, accounting for 74.43-95.70 % of total variations. The interactions between genotype and season were significant for all characters. Forty-nine corn genotypes were divided into four groups based on antioxidants and their activities. Significant and positive correlations were found among the anthocyanins, phenolics, and antioxidant activities, and correlation coefficients between anthocyanins with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability and Trolox equivalent antioxidant capacity (TEAC) assays were high (r = 0.94 and 0.88, respectively). All of the Hunterlab color parameters, including chroma and hue angle were highly correlated with anthocyanins, phenolics and their activities and therefore could be used as indirect selection criteria for improving levels of antioxidants and antioxidant activity in waxy corn.

Carotenoid and anthocyanin contents of grains of Brazilian maize landraces

Abstract: Our findings suggest that the colored grains of maize landraces studied may hold promise for the development of grain-based functional foods or natural colorants regarding their carotenoid and anthocyanin contents and as genetic resource in breeding programs.
