Abstract
The positive health benefits of colored staples have led to a significant increase in interest in them as healthy food ingredients. Numerous in vitro and in vivo studies have demonstrated that colored cereals are rich in antioxidants, carotenoids, and xanthophylls, which are widely used as natural additives in the food industry. Additionally, shifts in consumer preferences have led to a preference for nutritionally balanced diets over traditional high-energy ones. Thus, colored cereals offer additional nutritional value that has been previously untapped. Besides providing essential nutrients, these natural pigments also have the potential to replace synthetic colors and food additives. This review aims to provide insights into the nutritional value of various colored staples compared to conventional starchy staples and their associated health benefits. Colored staples can be incorporated into daily diets, offering a nutritious and healthful addition to the table.

Abstract
Interest in colored rice has been increasing due to its health benefits. This study examined the metabolite profiling of CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) mutated rice seed (yel-mutant). The wild-type (WT) and the yel-mutant having yellow (y)- and purple (p)-pericarp variants from Chucheong (cc) and Samkwang (sk) cultivars were investigated for differences in bioactive metabolite profiles and free radical scavenging activity. The total fatty acid content decreased by >50% in the yel-mutant against the WT, while no significant difference was observed between yellow- and purple-pericarp variants (p < 0.05). The yel-mutant of both cultivars showed significantly higher flavone contents than their WT (non-detected). Most of the metabolites examined were highly produced in the yel-cc-p and the yel-sk-y than in the other phenotypic variants studied. This study provides further useful information for colored rice breeding by revealing the detailed biofunctional metabolic profile under COP1 mutation in colored rice.

Aydin E. Investigation of some bioactive compounds, in vitro bioaccessibility, and sensory acceptability of couscous produced by pre-gelatinized rice flour. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2023; 103:2207-2214. [PMID: 36357184 DOI: 10.1002/jsfa.12330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 11/04/2022] [Accepted: 11/11/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND The purpose of this study was to investigate the sensory properties, antioxidant capacities, total phenolic content, and their bioaccessibility in gluten-free rice couscous that is produced without additives. Since rice does not contain gluten, pre-gelatinized rice flour (GRF) was added instead of gum and enzymes in order to provide the desired structure in the couscous samples. RESULTS According to the results, the total phenolic content of couscous samples was increased with GRF addition. The highest extractable and hydrolyzable antioxidant capacity values were observed in the couscous samples supplemented with 30% GRF using the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical cation, cupric-reducing antioxidant capacity, and ferric reducing antioxidant capacity methods. The bioaccessibility of antioxidant capacity was found to be significantly higher (P < 0.05) than the control sample in all methods except the 1,1-diphenyl-2-picrylhydrazyl free radical method in the couscous samples. CONCLUSION According to the data obtained, it has been determined that couscous, which has a very small round shape, can be produced with GRF without additives. In this context, gluten-free rice couscous could be used as an alternative valuable food in terms of nutrition and can be an alternative traditional food for celiac diseases as well as for individuals preferring the consumption of gluten-free products. © 2022 Society of Chemical Industry.

Limosilactobacillus reuteri Fermented Brown Rice: A Product with Enhanced Bioactive Compounds and Antioxidant Potential. Antioxidants (Basel) 2021; 10:antiox10071077.

Abstract
Oxidative stress has been postulated to play a role in several diseases, including cardiovascular diseases, diabetes, and stress-related disorders (anxiety/depression). Presently, natural plant-derived phytochemicals are an important tool in reducing metabolomic disorders or for avoiding the side effects of current medicinal therapies. Brown Rice (Oryza sativa L.) is an important part of Asian diets reported as a rich source of bioactive phytonutrients. In our present study, we have analyzed the effect of different lactic acid bacteria (LABs) fermentation on antioxidant properties and in the enhancement of bioactive constituents in Korean brown rice. Therefore, the antioxidant activities and phytochemical analysis were investigated for raw brown rice (BR) and different fermented brown rice (FBR). BR fermented with Limosilactobacillus reuteri, showed the highest antioxidant activities among all samples: DPPH (121.19 ± 1.0), ABTS (145.80 ± 0.99), and FRAP (171.89 ± 0.71) mg Trolox equiv./100 g, dry weight (DW). Total phenolic content (108.86 ± 0.63) mg GAE equiv./100 g, DW and total flavonoids content (86.79 ± 0.83) mg catechin equiv./100 g, DW was also observed highest in Limosilactobacillus reuteri FBR. Furthermore, phytochemical profiling using ultra-high-performance liquid tandem chromatography quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS) and cell antioxidant assay (CAA) revealed L. reuteri FBR as a strong antioxidant with an abundance of bioactive compounds such as gamma-aminobutyric acid, coumarin, cinnamic acid, butanoic acid, ascorbic acid, nicotinic acid, and stearic acid. This study expanded current knowledge on the impact of fermentation leading to the enhancement of antioxidant capacity with an abundance of health-related bioactive compounds in BR. The results obtained may provide useful information on functional food production using fermented brown rice.

Abstract
Free radical-induced oxidative stress is the root cause of many diseases, such as diabetes, stress and cardiovascular diseases. The objective of this research was to screen GABA levels, antioxidant activities and bioactive compounds in brown rice. In this study, we first fermented brown rice with different lactic acid bacteria (LABs), and the best LAB was selected based on the levels of GABA in the fermentate. Lactobacillus reuterii generated the highest levels of GABA after fermentation. To ascertain whether germination can improve the GABA levels of brown rice, we compared the levels of GABA in raw brown rice (Raw), germinated brown rice (Germ), fermented brown rice (Ferm) and fermented-germinated brown rice (G+F) to identify the best approach. Then, antioxidant activities were investigated for Raw BR, Germ BR, Ferm BR and G+F BR. Antioxidant activity was calculated using a 2,2-diphenyl-1-picryl hydrazile radical assay, 2,2-azino-bis-(3-ethylene benzothiozoline-6-sulfonic acid) radical assay and ferric-reducing antioxidant power. In Ferm BR, DPPH (114.40 ± 0.66), ABTS (130.52 ± 0.97) and FRAP (111.16 ± 1.83) mg Trolox equivalent 100 g, dry weight (DW), were observed as the highest among all samples. Total phenolic content (97.13 ± 0.59) and total flavonoids contents (79.62 ± 1.33) mg GAE/100 g and catechin equivalent/100 g, DW, were also found to be highest in fermented BR. Furthermore, an untargeted metabolomics approach using ultra-high-performance liquid tandem chromatography quadrupole time of flight mass spectrometry revealed the abundance of bioactive compounds in fermented BR, such as GABA, tryptophan, coumaric acid, L-ascorbic acid, linoleic acid, β-carotenol, eugenol, 6-gingerol, etc., as well as bioactive peptides which could contribute to the health-promoting properties of L. reuterii fermented brown rice.
