“…SY had higher Ca and Na levels than the others. According to reports, the amount of vitamins and minerals in rice varied depending on the source and species (Parengam et al ., 2010; Lichanporn et al ., 2020). In terms of vitamin and mineral content, all of the brown rice samples evaluated can be considered a natural source of nutritional components.…”

“…Niacin was abundant in SY, and a-tocopherol was abundant in NK. Brown rice is a good source of niacin and vitamin E in general (Parengam et al, 2010;Lichanporn et al, 2020). Brown rice often included thiamine (0.29 mg/ 100 g), riboflavin (0.05 mg/100 g), niacin (4.0 mg/ 100 g) and a-tocopherol (0.8 mg/100 g), according to Sen et al (2020).…”

This study aimed to determine the nutritional, physicochemical and bioactive characteristics of brown rice from the Noui Khuea (NK) cultivar, a non-pigmented short grain from Southern Thailand, in comparison with commercial non-pigmented long-grain Hom Mali (HM) and pigmented long-grain Sung Yod (SY) cultivars. The A-type XRD pattern was found in all samples of flour. All starch granules had a spherical shape with variable diameters (3.1-3.9 lm). The discrepancies in pasting properties across rice flours were explained by variances in compositions, particularly the amylose level. NK was classified as a high amylose rice, whereas SY and HM were classed as intermediate and low amylose types, respectively. Protein, minerals (phosphorus, potassium, magnesium, manganese, zinc and iron) and a-tocopherol were all higher in NK. SY showed the highest total phenolic content (29.38 mg GAE/g), largely in bound form. Several phenolic compounds (e.g. phenolic acids, esters and glucosides) were discovered. NK extract had the highest ACE-inhibitory activity (72.12%), but SY extract showed the strongest DPPH • /ABTS •+ inhibitions, FRAP and a-amylase/a-glucosidase inhibitions. Thus, the rice variety had a significant impact on its quality and bioactivity, and NK could be a viable alternative for both domestic and industrial use as a functional food ingredient.

Here is presented a study to investigate the geographic variation in rice grain nutrients (trace and macro-elements and vitamins) and toxicants (arsenic species and cadmium) across a contiguous strip of 36 districts that constitute western Bangladesh. The survey collected ~ 500 market rice samples, averaging 15 samples and 10.7 cultivars per district. New LC-MS methods were developed for rice relevant, B and E complex compounds. Cadmium and zinc decreased southward, while copper, DMA, inorganic arsenic and oryzanols decreased northwards. There was a longitudinal gradient for iron, potassium, and vitamin B6. The greatest changes ~ twofold for cadmium and vitamin B6, and 1.5 for zinc across these gradients. The gradients may be driven by climate, geographical setting, soils, or cultivar, or a combination of all. The most obvious gradient was the transition from high to low altitude and from Pleistocene to Holocene soils as land transitioned from the upland plains of the north to sea-level in the south. Rice is a very important source of copper, phosphorus, vitamin B1, and zinc, and to a lesser extent iron, B3, B6, potassium. It is a poor source of vitamin E and calcium.
