... High phosphorus steel slag and carbonized rice husk are two common wastes characterized by high generation and low secondary use values. Through the reduction of high phosphorus steel slag by biomass, both wastes were fully utilized, thus reducing the negative impact on the environment. In this study, variables such as temperature, time, and amount of reactants were changed to determine the optima ...

Abstract:
... Rice protein (RP) has attracted interest as a hypoallergenic protein. In this study, RP was used to improve cooking quality, physicochemical properties, and sensory attributes of gluten-free rice spaghetti (GFRS). GFRS samples were developed by replacing rice flour with rice protein concentrate at 0% (control), 2.5%, 5.0%, 7.5% and 10% (w/w), processed through a single screw extruder. Pasting prop ...

Abstract:
... Waxy, low-amylose and high-amylose rice starches were chosen to separate inner blocklets and outer shell from their granules under incomplete gelatinization. Isolated outer shells and swollen or merged inner blocklets, based on morphological structure of broken granules, were used as a probe to study the mechanism of differences between outer and inner blocklets formation, through molecular charac ...

Abstract:
... Though the retrogradation property as affected by starch fine molecular structures has been widely investigated, it remains largely unexplored how concurrent starch structures and storage conditions e.g. temperature tailor the starch retrogradation property. The amylopectin long-term retrogradation for 8 different rice starches with a broad range of amylose content was thus investigated under diff ...

Abstract:
... Aerodynamic separation of rice husks from brown rice grains after paddy husking is one of the important processes in rice processing. So far, the realisation of complete separation of rice husks from brown rice is still a challenging task. In this study, computational fluid dynamics (CFD) and discrete element method (DEM) were used to simulate the process, and the simulation results were verified ...
... Ovarian tumor domain (OTU)-containing deubiquitinating enzymes (DUBs) are an essential DUB to maintain protein stability in plants and play important roles in plant growth development and stress response. However, there is little genome-wide identification and analysis of the OTU gene family in rice. In this study, we identified 20 genes of the OTU family in rice genome, which were classified into ...

Abstract:
... Four types of cereals (glutinous rice, purple rice, red rice, yellow millet) were selected to produce sweet fermented grains. Flavor profiles of sweet fermented grains are comparatively studied to distinguish various flavor types by using GC-MS, electronic nose (E-nose), and sensory analysis, and the amino acid composition and physicochemical properties of sweet fermented grains were analyzed. The ...
... Amylase represents a green and healthy method that can be used to inhibit retrogradation of starch and high starchy foods. In this study, glutinous rice starch is hydrolyzed using α‐amylase or β‐amylase at different dextrose equivalent (DE) values to investigate the effect of enzymatically‐hydrolyzed glutinous rice starch (EGS) on the anti‐retrogradation of rice cakes. The latter's hardness shows ...

Abstract:
... As it has been reported that type 2 diabetes mellitus increases the risk of Alzheimer’s disease, we investigated how to prevent type 2 diabetes and dementia using biofunctional boiled rice. We adopted unpolished super-hard rice (SHBR) for diabetes and wax-free unpolished black rice (WFBBR) for dementia and blended those with ordinary non-polished rice (KBR) (blending ratio 4:4:2), adding 2.5% waxy ...

Abstract:
... Biochar has been used as an amendment in Cd-contaminated soils. However, the mechanisms of which biochar reduce Cd mobility and rice (Oryza sativa L.) Cd uptake by modifying the iron and sulfur cycling in soil has rarely been addressed in the literature. A pot experiment has been carried out with two Cd-contaminated paddy soils (FG and DBS) from South China. Rice straw biochar (RSB) and rape straw ...

Abstract:
... Phytochemicals are unevenly distributed in grain kernels and concentrated in bran fractions. However, their specific distribution in the grain bran, especially colored grains, is not clarified. This study divided rice bran from black rice into five fractions by stepwise milling to obtain BF1(outermost layer) to BF5 (the innermost layer). Each fraction accounted for approximately 2% of the whole ke ...

Abstract:
... On-site open burning is a common practice for handling rice straw, but its negative impacts, e.g., biomass loss and air pollution, are largely debated worldwide. To address the negative effects of open burning, many efforts have been made to ‘ignite’ worldwide bans. However, these bans are likely based on a singular view in which some positive aspects of open burning are overlooked. In this study, ...

Abstract:
... Straw sizes were found to affect the methylmercury (MeHg) accumulation in rice grains induced by straw incorporation. The mechanism behind, however, still remains unclear. Here, we incorporated rice straw in different sizes (powder, 2 cm and 5 cm) into a Hg-contaminated paddy soil. Our results showed that straw sizes regulated the release of different fractions of organic matter (OM) in straw resi ...
... Noncanonical (non-B) DNA structures, including G-quadruplexes, R-loops, and various DNA alternate conformations, affect genome organization, stability, and activity. Very few non-B structures have been mapped across plant genomes. Recently, Ma et al. identified intercalated-motifs (cytosine-rich, four-stranded quadruplex DNA) in rice, expanding how non-B DNA may contribute to plant gene regulation ...

Abstract:
... Fortified rice kernels (FRK) are extruded rice‐shaped kernels manufactured by blending broken rice flour and vitamin–mineral premix. In this study, four parboiled and three raw rice with intermediate amylose content (20–24%) were processed to manufacture FRK. The system parameters (torque and die pressure), physicochemical properties (length, lightness, water absorption index and water solubility ...

Abstract:
... Plant-based proteins are very often used as carriers of different phenolic compounds. For that purpose, complexation of quercetin with almond and brown rice protein matrices was investigated. The amount of protein matrices was constant, while the concentration of quercetin varied (1 mM, 2 mM or 5 mM) during complexation. Dried complexes were investigated for quercetin amount (HPLC analysis) and an ...

Abstract:
... Rice bran oil, a valuable ingredient of rice bran (composed mainly of embryo and aleurone), is gaining increasing attention for its abundance and benefits for human health. To increase production, breeders have selected for enlarged embryos and thickened aleurone layers. However, breeding for the latter is impeded by the time-consuming and labor-intensive process of observation of aleurone traits. ...

Abstract:
... Rice noodle with excellent edible quality usually needs a dense gel network structure, but the dense structure is detrimental to the entry of water molecules during dried rice noodle rehydration. To combine the conflict requirements, we described the branching modification of rice starch using 1,4- α- glucan branching enzyme (GBE). Highly branched starch with a short cluster structure reduced frac ...

The objective of this study was to investigate the effects of the branched chain length (BCL) distribution of amylopectin and crystallinity on the gelatinization property and the quality of extruded rice noodle. From the three different types of rice flour (Palbangmi [PBM], Saegoami [SGAM], and Mimyeon [MM]) with high amylose contents, MM displayed higher levels of longer amylopectin branched chai ...
