“…Literature abounds with information on the production of ogi from maize (Bolaji, Adenuga-Ogunji, & Abegunde, 2017a;Okara & Lokoyi, 2012), millet (Inyang & Idoko, 2006;Olawale, Oyeleke, Akinro, & Olakunle, 2012), sorghum (Adelekan & Oyewole, 2010;Apotiola, 2013), or the combination of two or more of these cereals (Eke-Ejiofor, 2018; Odewole et al, 2017). However, despite being one of the most important cereal crops in the world, as well as the most economically important crop in developing countries (Ajala & Gana, 2015), there is dearth of information on the suitability of rice for ogi production.…”

In the present study, the physicochemical and sensory properties of ogi (a cereal‐based starchy fermented gruel) produced from two local rice varieties, Abakaliki and Tapa, were determined. Ogi from white maize served as the control. There was a gradual increase in temperature from approximately 28 to 30 °C during fermentation. White maize exhibited the highest acidity level throughout the fermentation period. Tapa and Abakaliki rice ogi samples (i.e., TRO and ARO, respectively) were higher in yields and amylose contents than white maize ogi (WMO). WMO had significantly (P < 0.05) lower moisture content (54.14%) than ARO (62.18%) and TRO (68.02%). The highest and lowest sedimentation rates recorded for WMO and TRO, respectively, were attributed to difference in moisture contents and granule bulk densities. WMO showed higher solubility indices (3.54 to 4.66%) at all the temperatures (60 to 100 °C) tested. TRO and ARO had higher final and setback viscosities, as well as pasting temperatures than WMO, but were lower in breakdown viscosity. Ogi samples from rice recorded significantly (P < 0.05) higher L* values and distinct color characteristics with reference to a sample from maize, and this was suspected to have partially influenced their higher preference by the panelists during sensory evaluation. Rice is not just suitable for ogi production but looks promising to enjoy even more consumer acceptability than maize in this respect. However, there are notable peculiarities, such as major roles attributable to amylose contents. Practical Applications The study confirms the potential of rice as a promising alternative to white maize in the production of ogi while comparing the quality attributes of products from the two cereal types. Results from the study represent useful scientific insights into the distinct variations in some properties of rice and maize during fermentation. Production of ogi from rice, such as Abakaliki and Tapa varieties, may present an effective strategy to support government's political will aimed at promoting local rice in Nigeria and in Africa at large.

“…In addition to that, the Bureau of Agricultural Statistics (BAS) reported that the rice production in the Philippines significantly increased from 15.77 million metric tons in 2010 to 16.68 million metric tons in 2011 and 18.03 million metric tons in 2012 [3]. With this, the accumulated millions of tons of waste rice hull generated annually poses a substantial problem for rice growers with regards to its disposal [1,4,5]. Rice hull (RH) contains 13-29 wt% inorganic compounds of which 87-97 wt% is silica and the RH composition depends on the rice variety, climate, geographic location, soil, and quantity of fertilizer used [4,[6][7][8].…”

Hence, waste rice hull can be a good source of silica and its utilization can circumvent disposal problem and can be an alternative renewable source of this compound.…”

“…Silica in rice husk can exist in either crystalline or amorphous state over various temperature ranges and its production is independent of the purification or pre-treatment methods but it is largely dependent on processing temperature [5]. Since rice hull is difficult to use in agriculture in the form of compost [6], it is most often reduced its volume through open field burning (which creates undesirable atmospheric pollution) or burying [4]. However, studies found that rice hull silica processed through open-field burning can reach up to 900 o C producing products that are already crystalline in nature which is also potentially dangerous to human respiratory system when inhaled [7].…”

Rice husk is the covering of rice seeds and a by-product of milling rice grain. This study is conducted to investigate the production of silica (SiO2) formed from waste rice hull (RH) at different processing temperatures and study its structure, morphology, and thermal properties. Thermal analysis by thermogravimetric analysis (TGA) of the dried RH showed two mass-loss steps associated to the moisture desorption and thermal decomposition. Powder X-ray diffraction patterns of the rice hull calcined at 550oC showed a purely amorphous SiO2structure while those calcined for 900oC for 1 hour and for 3 hours showed a glass-ceramics and crystalline SiO2structure, respectively. This structural result is supported by the results obtained from the FTIR and Raman analyses of the samples. On the other hand, the Scanning electron microscopy (SEM) images showed the morphology of the samples revealing an increasing particle and grain size of the samples calcined at higher temperatures and longer heat treatment duration. In addition, Energy dispersive X-ray (EDX) spectra of both amorphous and crystalline SiO2samples confirm that the sample contains mostly silicon and oxygen. Thus, in this study, the desired form of either amorphous or crystalline SiO2from waste rice hull can be successfully obtained by controlled heat treatment.

“…Consequently, it would be a big waste of noble raw material to throw it away, since it can be used in various industries such as electronics, construction, ceramics, chemical industry, manufacture of photovoltaic cells, among others [6]. A large number of uses for this waste have been reported in literature by authors such as [13,17,14,27,12,1,5,11]. Moreover, clay is composed of colloidal particles of diameter less than 0.005 mm, with high plasticity when moist, and when dried, forms lumps hard to dissociate by finger pressure [15].…”

In this study, different compositions based on rice husk carbon and kaolinitic clay aimed at obtaining ceramic filter were studied. Three compositions of 40, 60 and 80% rice husk of the total mass were prepared. The specimens were uniaxially compressed in rectangular shape at pressure of 28 MPa and were sintered at temperatures of 1100oC, 1150oC and 1200oC for 1 h. The sintered samples were characterized according to standard technique for linear shrinkage, water absorption, apparent porosity and flexural strength. Scanning Electron Microscopy (SEM) was also performed to check the average pore size, and X-Ray Diffraction (XRD) to verify existing crystalline phases, chemical analysis and mercury porosimetry. The X-ray diffraction results showed mostly alpha quartz peaks and mullite after sintering. Mercury porosimetry showed porosity of 44.33% and average pore size of approximately 8.33 μm for sample with 60% rice husk sintered at 1200°C.
