Rice bran is a by-product of the rice milling process which contain a high concentration of protein. It’s are often used as a feed cattle, fertilizer, and fuel. Its application as a source of human nutrition is rare due to high lipid concentration. This lipid concentration can be reduced through the extraction process. After the extraction process, the rice bran extract needs to be converted into powder form through a drying process for the quality preservation. In this study, spray drying is utilized as drying technique. The aims of this study were to optimize the spray drying parameter; inlet temperature, feed flowrate and air flowrate for rice bran protein (RBP) powders production. Box Behnken Design (BBD) model in response surface methodology (RSM) are utilized in this study to maximize the RBP powder yield and protein concentration. Raw rice bran (RRB) was extracted using thermal water-based extraction method before the drying process. The optimum condition suggested by the model are at the inlet temperature of 120oC, feed flowrate of 18.38% and air flowrate of 670 L/hr which produced RBP powder yield of 19.42 g RBP/100g RRB and protein concentration of 17.32 mg/ml. The model obtains in this study show a low error between the predicted value and experimental data at 1.68 % and 1.14 % for RBP powder yield and protein concentration respectively. The model can be used to evaluate the process characteristic and understanding.

Rice bran is a by-product of the rice milling process. It contains a high concentration of protein. Rice brans are frequently utilized as feed cattle, fertilizer, and fuel. However, their application as human nutrition supplements is uncommon, and the necessary process for this purpose is yet to be established, including the drying process. This study aims to evaluate the effect of the spray-drying parameters, the inlet temperature, inlet flowrate, and inlet air flowrate, on rice bran protein (RBP) powder and optimize it using response surface methodology (RSM). A thermal water-based extraction method was utilized prior to the drying process. The correlation between the spray-drying parameters, i.e., the inlet temperature (120 to 210 °C), feed flowrate (5 to 55%), and air flowrate (246 to 670 L/h), and the RBP yield were investigated. The quality of the RBP powder was evaluated based on acid amino profiling in the mixture through de novo peptide sequencing. The optimized operating conditions for the maximum yield of RBP powder (25.7 g RBP/100 g RRB) are 178 °C, feed flowrate of 25%, and air flowrate of 450 L/h. The main peptides that contribute to RBP powder protein are globulin and glutelin; meanwhile, prolamin is believed to degrade during the drying process. The process also produced protein sugar, helping to produce fine particles powder without the drying agent.

Rice bran, a by-product of rice milling, contains four protein types – albumin, globulin, prolamin, and glutelin – known for their hypoallergenic nature and nutritional advantages. To enhance rice bran's worth, its protein was isolated using deep eutectic solvent (DES). The influence of three operational factors (temperature, extraction time, and rice bran to DES ratio) on protein yield was evaluated post-conversion using three level factorial design. Optimal conditions at 80°C, 3 hours, and 1:5 rice bran to DES ratio yielded the highest extracted rice bran protein (RBP) at 17.49%. Temperature and solvent-to-sample ratio show the lowest p-value, indicating a significant effect on the RBP yield. The validation test shows an error of less than 5% between the experimental and the predicted value, showing the model can be used to predict the RBP yield. The RBP was then characterised using Fourier Transform Infrared Spectroscopy (FTIR), Bradford Assays and SDS-PAGE electrophoresis to confirm the protein presence in rice bran powder. FTIR analysis showed the existence of amide I, amide II, aliphatic groups and amine or hydroxyl groups in the RBP. Furthermore, Bradford assays analysis indicated 23.89 ± 0.75% protein content in rice bran powder. SDS-PAGE electrophoresis shows the existence of Albumin and globulin in the RBP. In conclusion, a full three level factorial can be used to model and predict the optimal condition for protein extraction from rice bran using ChCl-Gly DES.

Rice bran is a by-product resulting from the milling process that is frequently underutilized as cattle food or disposed through open-burning despite of its high nutritional and nutraceutical properties. Thus, this research aims in recognizing and exploring rice bran and its extraction methods that could further cultivate in the industry. This study focuses on the rice bran extraction process using water assisted with ultrasonication. The relationship between the operational parameters such as the temperature, extraction time and sample-to-solvent ratio to the protein yield were studied. The rice bran protein was subjected to the surface functional group analysis using Fourier-transform infrared spectroscopy (FTIR). As a conclusion, the extraction temperature of 60°C, sample to solvent ratio of 10 % and extraction time of 25 mins were chosen as the best conditions for the protein extraction. The extraction of the protein from rice bran is highly profitable due to its nutritional and nutraceutical properties as well as it is readily available at low cost.

2023-06-09 , Kasman N.A.S. , Mohd Sharizan Md Sarip , Mohd Asraf Mohd Zainudin

The effect of drying process of the water extracted rice bran powder on the protein-thiol and physicochemical properties was investigated. The rice bran extracted was prepared with water as solvent at high temperature and pressure using the autoclave equipment (121 °C, 15 psi, and 20 min) before undergone drying method using either spray dryer (BṺCHI Mini Spray Dryer B-290, LABOGENE, Denmark) or freeze dryer (CoolSafe 4-15L Freeze Dryers, LABOGENE, Denmark). The water-extracted rice bran powder (WRBP) yield, protein-free thiol compound, physical and functional properties were analyzed. The protein-thiol concentration was quantified using the 5,5 dithiobis (2-nitrobenzoic acid (DTNB) method while protein concentration was directly measured at 280 nm by UV-Vis Spectrophotometer. This was followed by physical properties (water solubility) and functional properties (foaming capacity and stability, water and oil absorption capacity) analysis. The powder yield of freeze-dried WRBP (7.69 ±0.29%) was significantly (p<0.05) higher than spray-dried WRBP (4.43 ±0.24%). The protein concentration of spray-dried WRBP (4.02 ±0.36 mg/mL) was higher than freeze-dried WRBP (3.91 ±0.75 mg/mL). Meanwhile, freeze-dried WRBP (1.22 ±0.36 nmol thiol/mg protein) had a higher thiol concentration than spray dried WRBP (1.18 ± 0.30 nmol thiol/mg protein). However, both results were not significantly different (p>0.05) between the drying method. Spray-dried WRBP had significantly (p<0.05) higher solubility in water compared to that of freeze-dried WRBP with values 1.22 ± 0.21% and 0.63 ± 0.34%, respectively. Freeze-dried WRBP had higher water and oil absorption capacity. There was no significant difference (p>0.05) in foaming capacity and stability for both drying treatments. In conclusion, the drying method for WRBP production could significantly affect the WRBP physicochemical properties.
