Special Issue Information

Dear Colleagues,

For both humans and animals, cereals are the primary source of many nutrients, including proteins, carbohydrates, fiber, vitamins, and minerals. Most quality evaluation efforts and regulations around the world focus on the macro-components of cereals, such as protein content and functionality, when evaluating the merit of cereal varieties for a specific end-use product. However, consumers are demanding food products that offer health benefits beyond their nutritional value and that are more environmentally sustainable. Therefore, this Special Issue focuses on research concerning phytochemical analyses of cereals across a broad scope. Phytochemicals are plant secondary metabolites with many critical roles, including defense against biotic and abiotic stresses. However, their existence in cereal-based food products provides extra health-promoting functionalities such as anti-inflammatory, antioxidant, and anticancer properties. New-developed cereal grain varieties, as well as ancient grains, exhibit unique phytochemical profiles. Current breeding efforts aim to increase the level of these phytochemicals in new crosses in order to produce healthier cereals. On the other hand, grain/food processing would significantly affect phytochemicals’ content and functionality. Additionally, whole cereal grains are a good source of vitamins and minerals, but their concentration and bioavailability vary greatly with genotype, environment, management, and processing. Efforts to improve micronutrient quality in cereal grain through biofortification, enrichment, fortification, and bioprocessing are explored and practiced worldwide to fight hidden hunger.

This Special Issue aims to highlight any recent research regarding phytochemical and micronutrient analyses of cereals and the investigation of their functionalities.

Millets are group of underutilized cereal crops with higher nutritional values. The present investigation used different classes of minor millets, including barnyard (sava), little (kutki), finger (ragi), kodo and foxtail millets, for evaluation of their nutritional parameters, i.e., the content of proteins, total amino acids, total sugars, insoluble fibers, soluble fibers, total dietary fibers, iron (Fe) and zinc (Zn), along with antinutritional and antioxidant parameters, viz., tannic acid, phytic acid, phenol, flavonoid, proline and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. Alpha amylase and alpha glucosidase activity were also thought to elevate millets as a viable staple meal. Foxtail millet showed the maximum inhibition, with an IC50 value of 20.46 ± 1.80 µg mL−1 with respect to α-amylase. The coefficient of correlation between nutritional and antinutritional compositions showed that the starch content was significantly and positively correlated with insoluble fiber (r = 0.465) and dietary fiber (r = 0.487). Moreover, sugar was positively correlated with the phytic acid (r = 0.707), Fe and Zn (r = 0.681) contents. To determine the peptides responsible for anticancer activity, the foxtail protein was subjected to ultrafiltration; it was found that the 3 kDa fraction retained the greatest anticancer activity. Selected millet germplasm line(s) that have the best nutraceutical properties could be used in millet improvement programs. Full article
