PublicationReduced Graphene Oxide UWB Array Sensor: High Performance for Brain Tumor Imaging and Detection( 2023-01-01)
;Jamlos M.F. ;Othman N.A.A low cost, with high performance, reduced graphene oxide (RGO) Ultra-wide Band (UWB) array sensor is presented to be applied with a technique of confocal radar-based microwave imaging to recognize a tumor in a human brain. RGO is used to form its patches on a Taconic substrate. The sensor functioned in a range of 1.2 to 10.8 GHz under UWB frequency. The sensor demonstrates high gain of 5.2 to 14.5 dB, with the small size of 90 mm × 45 mm2, which can be easily integrated into microwave imaging systems and allow the best functionality. Moreover, the novel UWB RGO array sensor is established as a detector with a phantom of the human head. The layers’ structure represents liquid-imitating tissues that consist of skin, fat, skull, and brain. The sensor will scan nine different points to cover the whole one-sided head phantom to obtain equally distributed reflected signals under two different situations, namely the existence and absence of the tumor. In order to accurately detect the tumor by producing sharper and clearer microwave image, the Matrix Laboratory software is used to improve the microwave imaging algorithm (delay and sum) including summing the imaging algorithm and recording the scattering parameters. The existence of a tumor will produce images with an error that is lower than 2 cm. -

PublicationPrediction of phase equilibria in ternary diagram for system consist of Hot Compressed Water (HCW) with crude palm oil (CPO) and others minor component using thermodynamic model( 2024-05-10)
;Idham Z.Knowledge on phase equilibria for the separation process are important. It helps to improve the extraction efficiency through parameter optimization. Nowadays, hot compressed water extraction (HCWE) is getting the interest for the crude palm oil (CPO) extraction. Therefore, the phase equilibria of system consist of Hot compressed water (HCW) and CPO component are crucial. In this study, prediction of phase equilibria in ternary diagram for system consist of HCW with CPO and others minor component was conducted using thermodynamic model. The prediction was conducted using modified UNIFAC. CPO and other minor components namely palmitic acid which represent FFA, β-carotene, α-tocopherol, α-tocotrienol and α-tocotrieno was totally insoluble in HCW. The solubility of HCW in CPO was effect by the temperature and concentration of palmitic acid, β-carotene and α-tocopherol. However, the effect of these minor component concentration was inrrelevant since the concentration of these component was lower in the CPO for less than 1%. The solubility of HCW in CPO need to be monitored to avoid the hydrolysis which can deteriorate the CPO and degrade its quality. -
PublicationEffect of Nozzle Diameter on Temperature Behavior in Spray Dryer Via Computational Fluid Dynamics( 2022-01-01)
;Mohammad Azrul Rizal Alias ;Yang L.W. ;Samat A.A. ;Raja Ibrahim R.M.Z.Shabri M.S.M.Spray dryer comes at the end of the processing line since it is a critical step in monitoring the quality of the final product. It has certain advantages such as rapid drying rates, a wide range of operating temperatures and short residence times. This research focuses on the effect of inlet air temperature in the spray dryer chamber. The result from previous studies has shown that the increment of the inlet air temperature has caused the dying rate to increase. From the simulation, we have identified the performance in the spray dryer with different inlet air temperature as the parameter. The higher the inlet air temperature, the less the number of incomplete particles inside the spray dryer chamber, the more the success of the drying particles. The most optimized condition of inlet air temperature inside the spray dryer chamber from different parameters was identified as 225 K after the analysis on the results of simulation data. The main impact of this study is to increase the efficiency of drying particles inside the spray dryer chamber via computational fluid dynamics. In conclusion, researchers should concentrate more on the feed inlet air temperature of spray drying for future analysis because it plays an important role that can influence the impact on droplet conversion. -

;Rizuan Mansor M. ;Surya Krishnan T.Afandi Saidi S.Abstract.Rice bran is quite a novel subject in the food and pharmaceutical research area. It is the by-product of the rice milling process that is rich in proteins and many other nutrients. However, rice bran is commonly used to feed cattle, also as fertilizer and fuel but not as a source of nutrients for humans. Thus, this study proposes another protein source and explore its production methods for food and supplement industry. This research focuses to produce rice bran protein powder and protein concentration using spray drying technique. Since rice bran protein is used in food consumption, the extraction of protein from rice bran was done using physical extraction method which water as the medium of extraction. The relationship between the spray drying parameter; inlet temperature (130 - 200°C), feed flowrate (10 - 40%) and air flowrate (225 - 625L/Hr) were investigated based on the OFAT method, As conclusion, spray drying process of rice bran protein powder has the capability to maintain the nutritional value present in the rice bran. Rice bran protein powder could be an alternative source of hypoallergenic plant-based protein supplement to humans in the future with further research. -
Publicationβ-carotene enrichment in crude palm oil using subcritical water extraction and its relationship with the solubility(Elsevier, 2023)
;Noor Azian Morad ;Mustafa Kamal Tun Abdul AzizSyaripah Za'imah Syed JaaparSubcritical water extraction (SWE) was applied for β-carotene enrichment in crude palm oil (CPO) extraction. Investigated SWE operating condition were the pressure of 30, 40 and 50 bar and temperature from 120 to 180 °C. SWE processes were conducted semi-batch for up to 60 min of extraction time. Dynamic method using low solvent rate was used to develop the solubility trend for β-carotene. The pressure and temperature in SWE process gave significant effect to the β-carotene concentration as determined by f value (2, 18) = 158.26, p < 3.78 × 10−12 and f value (3, 18) = 5.91, P < 5.43 × 10−3 respectively. Maximum β-carotene concentration of 857.72 ± 0.34 ppm is obtained at 160 °C and 40 bar. The process was successfully modelled using second order mass transfer coefficient model with r2 between 0.939 and 0.995. Solute solubility cannot be associated directly to extraction efficiency in SWE process for β-carotene enrichment. -

PublicationOptimization of Rice Bran Protein Extraction Using Choline Chloride-Glycerol Deep Eutectic Solvent Using Response Surface Methodology (RSM)( 2023-01-01)
;Kamal Ramlee K.A.F. ;Muhammad Nor I.N. ;Mohd Zainudin M.A. ;Nawawi M.A.A by-product of the rice milling process, rice bran contains four different types of protein: albumin, globulin, prolamin, and glutelin. These proteins are widely known for being hypoallergenic and having nutritional benefits. In order to increase the value of rice bran, the protein was extracted via deep eutectic solvent (DES). Response Surface Methodology (RSM) was used to assess the impact of three operational conditions, including temperature, extraction duration, and the ratio of rice bran to DES, on the yield of rice bran protein after the precipitates were converted into powder form by freeze drying. At optimal working conditions, which were 60 °C, 2 h, and a 1:9 ratio of rice bran to DES, the method’s results showed that the highest extracted protein of rice bran was 16.254%. Several techniques, including Fourier transform infrared spectroscopy (FTIR) and Kjeldahl studies, have been used to demonstrate the presence of protein in rice bran powder. In the rice bran protein (RBP), amine (1640.70 cm−1), alcohol (3229.74 cm−1), and alkane (2925.37 cm−1) were all detected using FTIR analysis. Furthermore, Kjeldahl analysis revealed that 15.61% of the rice bran powder’s protein content is present. In conclusion, rice bran’s value as a functional meal can be increased by adding protein through the use of a deep eutectic solvent called green solvent.3 21 -

;Mohammad Azrul Rizal Alias ;Yang L.W. ;Abdullah Abdul Samat ;Raja Ibrahim R.M.Z.Shabri M.S.M.Spray drying is commonly used in the chemical and food industries and is the preferred drying process for many materials, such as dairy products, foods, pharmaceuticals, polymers, etc. This research focuses on the effect of the nozzle diameter in the spray drying region against velocity distribution. The results from previous studies have shown that CFD can be a useful tool for predicting the pattern of gas flow and particle histories such as temperature, velocity, time of residence and place of effect. The predictions from these model were validated against reported experimental results, and other simulations. From the simulation analysis, the present studies have identified the performance in the spray dryer through with different size of spray nozzle diameter as the parameter. For the nozzle diameter part, the smaller the spray nozzle diameter, the higher the velocity of the droplets with beneficial to the thermal efficiency of drying particles. The statements finding from the simulation of nine different case study with different nozzle diameter found that the higher velocity has been identified in simulation results due to incomplete vaporize droplets. The main impact of this study is to identify the most optimized condition of the spray dryer chamber after the analysis of the results of simulation data. In conclusion, the design on the chamber has many potential ways to be developed and improved. These findings will benefit the designing of spray dryers.1 16 -
PublicationSpray Drying Optimization for Rice Bran Protein (RBP) Powder Using Response Surface Methodology (RSM)( 2022-01-01)
;Mansor M.R.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.2 9
