Effect of Size Reduction Processes on Rice Flour Properties and the Quality of their Bakery Products

Currently, there is an incremental demand for ricebased products among health-conscious consumers in the dynamic food market. The method and the machinery used in the size reduction processes have a crucial impact on the physicochemical properties of rice flour, thereby affecting the quality and consistency of the final products. Consequently, certain starch modification techniques can be implemented to eliminate some baker-unfriendly properties associated with rice flour. This brief review is focusing on literature pertaining to different rice milling techniques, certain physicochemical and functional flour properties, a comparison of rice flour properties relevant to different rice milling techniques, the relationship between different rice flour properties and their effect on the quality of bakery products, and finally the improvement of flour properties by different starch modification techniques.

Market Concentration of Branded Rice in Kerala

In Kerala rice is a staple diet. As per the information from Kalady Rice Millers’ Consortium, 40 per cent of the consumers in Kerala prefer branded rice, and out of this Kerala absorbs only 16 per cent, the rest of the branded rice is from outside states like Andhra Pradesh, Tamil Nadu and West Bengal. This study investigates the market concentration of Kerala’s branded rice market, focusing on the dominance of a few key players and its market share, pricing power, and concentration. The analysis employs four-firm concentration ratio, the Herfindahl-Hirschman Index (HHI), Gini coefficient and the Lorenz curve to reveal an oligopolistic structure, where a small number of firms control a substantial portion of the market. Major players like Pavizham, Keerthi Nirmal, Periyar, Kottaram, and Jayabharath, alongside the Kalady Rice Miller’s Consortium, play a crucial role in shaping the branded rice market in Kerala. The study involved a survey conducted between November 2023 and June 2024, with a random sample of 10 non-exporters, 5 exporters, and one co-operative rice mill, selected from the 46 branded rice manufacturers in the state, predominantly from Ernakulam and Palakkad districts. The findings of the study highlighted that the branded rice market in Kerala had an oligopolistic behaviour. This research fills a gap in understanding the distribution of market power in Kerala’s rice industry and offers suggestions for fostering greater competition and inclusivity in the market.

Harnessing biomass waste-to-energy for sustainable electricity generation: prospects, viability, and policy implications for low-carbon urban development

AbstractBiomass waste-to-energy (WtE) generation is a potential pathway for green urban transition in developing countries which can contribute significantly to sustainable development goal 7: affordable and clean energy. However, unlike fossil fuel energy systems, the economic returns from WtE systems are low because WtE generation is capital-intensive and requires subsidies. This study examines the prospects of a sustainable biomass electricity generation from rice husk (RH) using a large dataset of rice milling activities in a fast paced urban transition economy. The study analyzes the viability of several RH biomass electricity generation scenarios using indicators such as net electricity output, economic returns (benefits), and levelized cost of electricity (LCOE). The results show that several mills/mill clusters generate sufficient daily RH that can power between 0.8 and 2.2 MW plant with a combined electricity output of about 500,000 MWh per annum. The economic analyses show that all RH biomass electricity generation scenarios return positive economic benefits under reduced social discount rates of 2–6%. Moreover, the LCOE of all scenarios are less than those of electricity generated from other sources. These results demonstrate that biomass waste-to-energy generation is viable for green urban development through low-carbon decentralized energy systems. Several policy implications of the findings are highlighted, including the need for policymakers and energy stakeholders to adopt sustainable biomass energy generation models such as “design, build, and operate” (DBO) to achieve sustainable WtE generation regimes that ensure green urban transition. Such a model will contribute to a circular economy and facilitates sustainable urban development that satisfies climate-related SDGs. Graphic abstract

The impact of milling degree on physicochemical, nutritional, rheological, textural properties, and in vitro digestibility of rice: From brown rice to white rice

The objective of this study was to characterize the rice milling fractions acquired at each stage of a commercial milling system. This characterization included an analysis of color, ash content, dietary fiber, mineral composition, as well as antinutritional compounds like phytic acid, trypsin inhibitor activity, and saponin. Additionally, we investigated in vitro starch and in vitro protein digestibility, along with pasting, cooking, and textural properties.Our findings revealed that milling improved the visual appeal of rice (e.g., volume expansion, weight gain, whiteness) and notably enhanced its starch digestibility. However, milling reduced dietary fiber, mineral content, antinutrients, cooking time, and texture characteristics such as hardness, chewiness, gumminess, springiness, and cohesiveness to varying degrees. Certain parameters, such as dietary fiber, exhibited a gradual change with the duration of milling, while others, such as mineral content and texture, showed significant variation at the initial stage of milling, particularly at the first mill.

The effects of milling on the chemical forms, bioavailability, and in vivo distribution of Vitamin B1 in rice

Milling not only reduces the content of Vitamin B1 (Vit B1) in rice but may even affect its bioaccessibility, further affecting its activity in vivo. Therefore, this study investigated the changes in Vit B1 content and its chemical forms in rice at different degrees of milling (DOM) before and after cooking, as well as their bioaccessibility in vitro and bioavailability in vivo. In raw unmilled rice, the proportion of bound Vit B1 was slightly lower than that of free Vit B1, and the proportion increased significantly after cooking. DOM< 8% hindered this change of bound Vit B1 after cooking, resulting in a decrease in Vit B1 thermal stability from 90% to 80% and bioaccessibility from 80% to 60%. Fortunately, the content of Vit B1 stabilized in the digestive fluid remained superior to that of the high DOM group. DOM<8% shortened the time for Vit B1 to peak in the blood concentration of mice, whereas the decrease in bioavailability of Vit B1 in blood and liver was insignificant, unlike bioaccessibility. Hence, DOM < 8% can be applied to the rice milling process to maintain nutritional value. Correlation analyses indicated that the bound form of Vit B1 in cooked rice was the main factor affecting its digestion and absorption. These findings provide further support for the development of moderate rice processing.

Industrial Pollution in Patna City : Physico-Chemical Analysis of Effluents and Their Effects on Water and Soil

Industrial pollution is a significant concern in Patna City, with rapid urbanization and industrial growth contributing to the degradation of natural resources. This study focuses on the physico-chemical analysis of industrial effluents and their effects on the water and soil quality in and around Patna. Effluents from various industries, including textile, sugar, rice mills, and small-scale manufacturing units, are released into nearby water bodies and soils, posing serious environmental risks. The research aims to assess the levels of pollutants by analysing key physico-chemical parameters such as pH, total dissolved solids (TDS), biochemical oxygen demand (BOD), chemical oxygen demand (COD), heavy metals (lead, chromium, cadmium), and organic contaminants in industrial effluents. Samples were collected from various locations near industrial zones and water bodies. The study also evaluated the impact of these pollutants on soil and groundwater quality. It was found that prolonged exposure to industrial effluents led to the accumulation of toxic metals in soil, reducing its fertility and altering its structure. Additionally, groundwater sources were contaminated with hazardous chemicals, making them unfit for drinking and irrigation purposes. The implementation of advanced treatment technologies and sustainable industrial practices is crucial for safeguarding the environment and public health in Patna City.

Starch lysophospholipids contents affect storage quality of paddy rice

Starch Lysophospholipids (LPLs) have a significant effect on rice grain quality, but how starch LPLs affect paddy rice storage quality is barely understood. The dynamic changes in storage quality indicators of a japonica rice (XS110) and its low LPLs (XS110-J1) and high LPLs (XS110-J2) mutants were investigated. The fatty acid values (FAV) of J1 were significantly higher than those of XS110 and J2 after one year of storage under 24 and 37 °C. Although FAV rose gradually during storage time, it increased relatively more at 37 °C than 24 °C. The malondialdehyde (MDA) content increased significantly in the early stage and decreased gradually during later storage. The MDA content of rice stored at 24 °C was significantly higher than that at 37 °C. The catalase (CAT) activity exhibited a decreasing trend during storage and was relatively higher at 24 °C than 37 °C. The CAT of J2 was significantly higher than those of XS110 and J1. Total lysophospholipid content was relatively stable although some individual LPLs changed significantly during storage. The fatty acid component content in the milled rice decreased during storage, and the content at 37 °C was lower than that at 24 °C. In conclusion, paddy rice with low starch LPLs content is more susceptible to deterioration during storage, suggesting that high starch LPLs can better maintain rice quality and prolong storage time during storage of paddy rice.

PROFITABILITY ANALYSIS OF RICE MILLING AND MARKETING IN BAUCHI STATE, NIGERIA

The study analysed the profitability of rice milling and marketing in Bauchi State, Nigeria. Multi-stage sampling procedure was used for the selection of respondents. The respondents comprised rice processors (millers) and marketers. Data were collected using questionnaire and analysed using descriptive statistics, farm budgeting techniques and multiple regression analysis. The findings revealed that majority (87.5%) of the millers and all (100%) of marketers were male and married with a mean age of 39 and 44 years respectively. However, 43.8% of the millers and 40% of the marketers had a family size of between 6-10 people per household with majority (62.5%) of the millers having tertiary education. The analysis also shows that half (50%) and more than half (53%) of the millers and marketers had a marketing and milling experience of between 11-20 years. The result of the budgeting model revealed that millers had a net income of N714 per bag with a return per naira of N1.46 and marketers had a net income of N1, 672 per bag with a return per naira of N 0.12. The results of the regression analysis revealed that years of milling experience and education level were the factors influencing rice milling while household size and membership of association were significant factors influencing rice marketers’ income. However, high cost of diesel (96.7%) and transportation cost (95%) were the major constraints faced by the millers and marketers in the study area. The study concluded that, milling and marketing of rice is a profitable ventures in the study area. It is therefore, recommended that government together with stakeholders should provide adequate infrastructure and introduce favorable policies to strengthen the rice value chain in the study area.

Physicochemical and Morphological Changes in Long-Grain Brown Rice Milling: A Study Using Image Visualization Technologies

This study evaluated the changes in physicochemical properties and appearance quality of long-grain rice during the grinding process using image technologies and aimed to provide reference for future research. The brown rice milling process was divided into three stages, and flatbed scanning, scanning electron microscopy (SEM), X-ray micro-computed tomography (micro-CT), low-field nuclear magic resonance (LF-NMR), and headspace–gas chromatography–ion mobility spectrometry (HS–GC–IMS) were employed to examine the physicochemical and volatile properties of the samples. Results revealed a continuous increase in the degree of milling, with a broken rice rate and a whiteness value increasing by 50.84% and 21.13%, respectively, compared with those during the initial stage; dietary fiber and vitamin B1 contents were reduced by 54.41% and 66.67%, respectively. The image results visualized showed that the cortex of brown rice was gradually peeled off with the increase in milling degree; the cortical thickness was gradually reduced, the endosperm was gradually exposed, and the surface was smoother and shinier. T2 populations exhibited a shift toward longer relaxation times, followed by a decrease in relaxation time during the milling process. Additionally, 31 target compounds impacting rice flavor, mainly ketones, alcohols, and esters, were identified, and the concentration of volatile substances in the B region decreased with the reduction in the bran layer; the concentration of volatile substances in the C region provided rice flavor, which increased with the milling process. This study showed changes in the physicochemical properties and appearance quality of long-grain brown rice during milling. Furthermore, the use of various image processing techniques offers significant insights for optimizing processing parameters and enhancing overall quality and taste.

Among them, compounds 5/6 had a significant antioxidant activity compare to that of vitamin E in both DPPH and reducing power assay up to the concentration 40 μg/ml; while compounds 1 and 2 exhibited weak suppressive effect on the production of nitric oxide, with the IC50 values of 53.27 ± 1.37 μM.

Sintesis Zeolit dari Abu Sekam Padi (OryzaSativa L.) Serta Uji Efektifitasnya Sebagai Material Antiseptik

Rice husks are obtained from 20% rice milling and have a silica content of 94-99% of ashed rice husks. Zeolite is a silica-based material and is known as an aluminosilicate compound, because it is formed from two main components, namely tetrahedral AlO4- and SiO4¬-. Synthetic zeolite is obtained by reacting Sodium Silicate (A) with Sodium Aluminate (B) which is then aged at 100oC for 24 hours to produce white synthetic Zeolite powder. Zeolite synthesis will be made with three variations of mixture ratios, namely 30A:70B, 50A:50B, 70A:30B and the characteristics of each will be evaluated. To test the success of this synthetic zeolite as an antiseptic material, its ability to reduce the infectious value of Bacteriuria and Candiduria will be tested, which will be represented by Escherecia coli and Candida albicans. The results obtained from the three variations of synthetic zeolite that were made had the same characteristics and had a ratio of less than two or type A. Synthetic zeolite made at a dose of 600 mg had the ability to act as an antiseptic material against Escherichia coli 104 by reducing the number of colonies to 72-79 %, as well as Candida albicans 103 was able to reduce the number of C. albicans colonies by 74-80%, this value is lower than Attapulgite 600mg in reducing the same number of colonies, namely 90% for bacteriuria and 94.90% for candiduria. To equalize its capabilities with Attapulgite 600 mg, the dosage of the synthetic zeolite obtained in the research was increased to 700 mg

Predictive modeling of rice milling degree for three typical Chinese rice varieties using interpretative machine learning methods.

Brown rice over-milling causes high economic and nutrient loss. The rice degree of milling (DOM) detection and prediction remain a challenge for moderate processing. In this study, a self-established grain image acquisition platform was built. Degree of bran layer remaining (DOR) datasets is established with image capturing and processing (grain color, texture, and shape features extraction). The mapping relationship between DOR and the DOM is in-depth analyzed. Rice grain DOR typical machine learning and deep learning prediction models are established. The results indicate that the optimized Catboost model can be established with cross-validation and grid search method, with the best accuracy improving from 84.28% to 91.24%, achieving precision 91.31%, recall 90.89%, and F1-score 91.07%. Shapley additive explanations analysis indicates that color, texture, and shape feature affect Catboost prediction accuracy, the feature importance: color>texture>shape. The YCbCr-Cb_ske and GLCM-Contrast features make the most significant contribution to rice milling quality prediction. The feature importance provides theoretical and practical guidancefor grain DOM prediction model. PRACTICAL APPLICATION: Rice milling degree prediction and detection are valuable for rice milling process in practical application. In this paper, image processing and machine learning methods provide an automated, nondestructive, and cost-effective way to predict the quality of rice. The study may serve as a valuable reference for improving rice milling methods, retaining rice nutrition, and reducing broken rice yield.

Potential antimicrobial and fruit juice clarification activity of amylase enzyme from Bacillus strains

The hydrolytic enzyme, amylase possesses wide industrial applications and its production from bacterial sources by submerged fermentation is much simplified and economical. The research aimed to characterize amylase-producing bacteria and evaluate their potential for amylase activity regarding antimicrobial and fruit juice clarification. In current study, Bacillus licheniformis, Bacillus amyloliquifaciens, Bacillus cereus, Bacillus subtilis and Bacillus paramycoides was identified by 16S rRNA sequencing. After submerged fermentation, amylase activity of bacteria was measured by 3, 5-dinitro salicylic acid (DNS) assay. A substantial amount of amylase (423.47 mg/ml) in crude extract was measured by Bradford protein assay. Later, ammonium sulfate (80 %) precipitated partially purified amylase showed 1.6 times enhanced amylase activity (1484.94 U/ml) compared to crude amylase (973.23 U/ml). For highest amylase production, 72 h of optimum fermentation period was recorded at pH 7 with 2 % starch as substrate. Potent thermophilic amylase activity was observed at 65 °C. In apple juice clarification activity of amylase, turbidity of juice was reduced to 54.18 %. Potential antimicrobial property of amylase was detected with largest zone of inhibition against Escherichia coli ATCC 25922 (22.36 mm) and Mucor sp. ATCC 48559 (22.45 mm). Considering promising amylase properties, amylase-producing Bacillus strains from rice mill soil can be fermented for large scale amylase production providing application for industrial purposes including fruit juice clarification and antimicrobial activities. It will also overthrow the requirement of employing expensive and harmful chemicals in fruit juice clarification and combating pathogens.

Arsenic contamination in rice consumption in Bandung city - West Java

Abstract Arsenic contamination in rice is of concern due to the potential health risks associated with various health problems, including certain types of bladder and lung cancers and skin lesions. Arsenic is a naturally occurring element that can be found in soil and water and its contamination in rice is possible. Meanwhile, rice is a staple food in Indonesia and its consumption is widespread across the country. According to the US Department of Agriculture, Indonesia is the world’s fifteenth-largest rice consumption with 128.6 kg per capita per year thus arsenic in rice is a concern. This study was conducted to measure the arsenic contamination in rice consumed by people in Bandung. Bandung was preferably selected due to its high population. As the capital city of West Java, its population hits more than 2.5 million and places it as the 5th most populated area in Indonesia. Ten rice samples were collected from a traditional market in Bandung, West Java. The sample was prepared using the Indonesian Regulation Standard (SNI) method and measured by ICP-MS. The arsenic concentration in rice was found varies between 0.0775-0.2550 mg/kg. The maximum allowable arsenic content for consumption based on the Indonesian National Standard (SNI) is 0.4 mg/kg, according to the World Health Organization (WHO) is 0.3 mg/kg, and according to the European Commission Standard for parboiled milled rice, the maximum level is 0.15 mg/kg. The HQAs value was higher than 1 (HQAs &gt; 1), the rice in Bandung Market have potential for non-carcinogenic risk in long-term. ILCRAs result in this study between ILCR &gt; 10−3 and &gt;10−4 indicates threshold cancer risk for rice consumption. By calculating the ILCR, scientists and policymakers can prioritize interventions, implement regulatory measures, and develop strategies to reduce exposure levels, ultimately mitigating the potential cancer risks within a given population. It is important to note that the study should be continued over the next few years, to monitor the potential health risks associated with consuming contaminated rice.

Multiomics of a rice population identifies genes and genomic regions that bestow low glycemic index and high protein content

To counter the rising incidence of diabetes and to meet the daily protein needs, we created low glycemic index (GI) rice varieties with protein content (PC) surpassing 14%. In the development of recombinant inbred lines using Samba Mahsuri and IR36 amylose extender (IR36ae) as parental lines, we identified quantitative trait loci and genes associated with low GI, high amylose content (AC), and high PC. By integrating genetic techniques with classification models, this comprehensive approach identified candidate genes on chromosome 2 (qGI2.1/qAC2.1 spanning the region from 18.62 Mb to 19.95 Mb), exerting influence on low GI and high amylose. Notably, the phenotypic variant with high value was associated with the recessive allele of the starch branching enzyme 2b (sbeIIb). The genome-edited sbeIIb line confirmed low GI phenotype in milled rice grains. Further, combinations of alleles created by the highly significant SNPs from the targeted associations and epistatically interacting genes showed ultralow GI phenotypes with high amylose and high protein. Metabolomics analysis of rice with varying AC, PC, and GI revealed that the superior lines of high AC and PC, and low GI were preferentially enriched in glycolytic and amino acid metabolisms, whereas the inferior lines of low AC and PC and high GI were enriched with fatty acid metabolism. The high amylose high protein recombinant inbred line (HAHP_101) was enriched in essential amino acids like lysine. Such lines may be highly relevant for food product development to address diabetes and malnutrition.

The structural-mechanical damage behavior of rice bran layer under tensile processing for moderate milling

Bran layer moderate removal during rice milling is a crucial process for reducing rice broken rate and nutrient loss. The bran layer structural-cracking behavior is analyzed using a self-developed in-situ observation tensile tester with high-speed image acquisition. The rice bran tissue microstructure, chemical composition, cracking morphology are in-depth investigated. The results show that rice bran pericarp cells are of reticulate network, cell shape with rectangular or elliptical.significant differences in cell distribution and density across rice varieties, with Japonica rice (NJ5055) with a denser and more uniform structure, exhibiting higher ductility and tensile strength. The rice bran exhibited linear elastic rheological behavior. The bran tensile property is different under tensing directions, the tensile strength shows longitudinal (Y) > radial (X). Cracking along the cell long axis is Y direction, showing orderly line cracking path. Cracking along cell short axis is X direction, showing zigzag cracking path. Pericarp cells geometrical structure determines the mechanical strength and cracking-removal resistance ability of rice bran. The pericarp layer significantly enhances the ductility of the bran layer, allowing it to stretch and deform under stress, thereby improving overall mechanical performance. Rice bran structural-mechanical properties are affected by micro-structure and components.
