SummaryThe field of metabolomics has undergone substantial growth, particularly in its application to cereals and their derived products. This comprehensive analytical technique offers insights into the complex and dynamic metabolic profiles of cereals and their derivatives, thereby contributing to a deeper understanding of the composition, quality, and nutritional aspects of these. Various techniques such as mass spectrometry (MS), chromatography coupled with MS, and nuclear magnetic resonance (NMR) were employed to explore the diverse range of metabolites present in cereals. Studies have focused on different aspects that alter the metabolic profile of cereals and their derived products. The present article elucidates the impact of factors such as genotype, growing conditions, and processing methods on the metabolite composition of cereals. Additionally, it has facilitated the identification of bioactive compounds with potential health benefits, contributing to the development of functional foods. Metabolomics approaches enabled the detection of different phenolics, and other essential metabolites in cereals and their derived products, and their modulatory effects on human health. The advances in metabolomics are considered as a powerful tool for developing innovative and healthier cereal‐based products.

“…2a). Such an increase in activity may arise from microwave heating-mediated release of bound phenolics and phytochemicals from the cellular components as well as Maillard reaction products produced in browning reactions (Patil et al, 2016;Liu et al, 2023). Infrared heating of rice bran under optimum conditions has also been reported to increase the DPPH free radical scavenging activity (Irakli et al, 2018).…”

The current study delves into the impact of microwave treatment with different wattage and durations on phytoconstituents, antioxidant status, anti-nutritional factors (ANFs), and metabolite profiles of de-oiled rice bran. The total phenolics and flavonoids exhibited both up- and down-regulation based on specific microwave parameters, while an overall up-regulation in flavonol content was observed across all treated groups compared to the control. The DPPH and ABTS free radical scavenging activity, total antioxidant capacity, FRAP, CUPRAC, metal chelating activity, and ascorbic acid content were enhanced in most of the microwaved samples; however, longer microwave exposure at higher wattage led to their diminution. A treatment-specific reduction was observed for ANFs, viz., condensed tannin, oxalate, and phytate. HR-MS-based untargeted metabolomics revealed diverse primary and secondary metabolites that clustered in a group-specific manner, indicating prominent group-wise metabolite variations. Analyses of discriminating metabolites revealed non-significant differences in the overall levels of phenolics, flavonoids, vitamins and cofactors, sugars, amino acids, terpenoids, fatty acids, and their derivatives among the various treated groups compared to the control; however, several individual metabolites within these metabolite classes differed significantly. The current findings suggest that optimized microwaving of de-oiled rice bran can enhance phytochemicals and antioxidants while improving the metabolite profile.

BACKGROUNDThis study investigated the effects of γ‐aminobutyric acid (GABA) combined with ultrasonic stress germination (AUG) treatment on the phenolic content and antioxidant activity of highland barley (HB). Key variables, including germination times (ranging from 0 to 96 h), ultrasonic power (200–500 W), and GABA concentration (5–20 mmol/L), were optimized using response surface methodology (RSM) to enhance the enrichment of phenolic compounds. Furthermore, the study assessed the content, composition, and antioxidant activities of phenolic compounds in HB under various treatment conditions such as germination alone (G), ultrasonic stress germination (UG), and AUG treatment.RESULTSThe study identified optimal conditions for the phenolic enrichment of HB, which included a germination time of 60 h, an ultrasound power of 300 W, and a GABA concentration of 15 mmol L−1. Under these conditions, the total phenolic content (TPC) in HB was measured at 7.73 milligrams of gallic acid equivalents per gram dry weight (mg GAE/g DW), representing a 34.96% enhancement compared to untreated HB. Notably, all treatment modalities – G, UG, and AUG – significantly increased the phenolic content and antioxidant activity in HB, with the AUG treatment proving to be the most effective.CONCLUSIONThese obtained results suggest that AUG treatment is a promising processing method for enriching phenolic compounds and improving antioxidant activity in HB. Subsequently, the AUG‐treated HB can be used to develop phenolic‐rich germinated functional foods to further broaden the application of HB. © 2024 Society of Chemical Industry.
