Item type:Publication, Rapid and accurate classification of Aspergillus ochraceous contamination in Robusta green coffee bean through near-infrared spectral analysis using machine learning(2023-03-01); ; ; Near-infrared (NIR) spectral-based classification of Aspergillus ochraceous contamination in the Robusta green coffee bean was investigated. Six different learning algorithms, including linear discriminant analysis (LDA), support vector machine (SVM), k-nearest neighbors (KNN), decision tree (Tree), Naive Bayes (NB), and quadratic discriminant analysis (QDA), were applied for the investigating purpose. Four classes of fungal contamination on coffee beans, non-fungal contaminated beans on day 1 and day 3 (NCB-D1 and NCB-D3) and fungal contaminated beans on day 1 and day 3 (CB-D1 and CB-D3), were set for the classification intention. Based on the 6 learning algorithms, the Tree approach was optimal, displaying a training accuracy of 97.5%. As proven by the testing dataset, the classification accuracy of the Tree was also at 97.5%. With this number, the Tree could correctly classify 100% between the contaminated and non-contaminated coffee beans. These findings exhibit the potential of the NIR spectroscopy accompanied by machine learning for the early detection of fungal contamination in green coffee beans. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Enhanced biodiesel purification using coffee husk bioadsorbents: The role of pyrolysis temperature, KOH activation, and adsorption efficiency(2025-05-01); ; ; ; Ruttanadech, NuttapongThis study evaluates the performance of bioadsorbents derived from coffee husk pyrolyzed at temperatures of 600, 700, and 800 °C (CH600, CH700, and CH800), along with activated CH700 (ACH700), in biodiesel purification. The results indicate that CH700 significantly enhances biodiesel purity, with optimal purification conditions achieved at a dosage of 2 wt% CH700, a stirring rate of 400 rpm, and a contact time of 45 min. CH700 demonstrated modest performance, achieving approximately 20 % removal of methanol and water. However, after activation with potassium hydroxide (KOH), ACH700 demonstrated improved efficiency, achieving 96.92 % methanol removal and 39.46 % water removal. ACH700 also refined biodiesel quality to meet EN14214 standards and maintained a higher biodiesel yield compared to other adsorbents. The bioadsorption process is influenced by the chemical interactions between the surface functional groups of the bioadsorbent and the contaminants, which is further enhanced by the optimized pore structure of ACH700. The use of ACH700 represents a novel and highly effective approach to biodiesel purification, combining both technical efficiency and economic feasibility. Furthermore, the valorization of agricultural waste adds significant environmental benefits, reinforcing the potential of ACH700 for large-scale biodiesel production. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Testing and evaluation of banana (‘Kluay Lab Mue Nang’) wholesale packaging in Chumphon province, Thailand under transport simulation(2019-01-01); This research evaluated the effects of foam packaging on wholesale packages of banana (‘Kluay Lab Mue Nang’) in Chumphon province, Thailand. The experiment was divided into 3 experimental sets, namely, 1) foam net (FN); 2) expanded polyethylene foam (EPE); and 3) controlled sample without use packaging (NOP) and damages were categorized into three types which were bruising, abrasion and laceration. Vibration tests were performed following the standard method of ASTM D999 Method A2 using the frequency of 4 Hz for one hour. Results revealed that the total damage of EPE (bruising, abrasion, and laceration) was higher than that of FN. When considering the percentage of damage area, it was found that the damage percentages of EPE caused by bruising and abrasion were 7.41 and 3.28%, respectively, and the damage percentages of FN caused by bruising and abrasion were 5.73 and 3.82%, respectively. There was no damage from laceration detected. The results showed that FN had the greatest reduction in damage. The controlled sample (NOP) had a total damage of 20.79%. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Quality attributes of parboiled rice prepared with a parboiling process using a rotating sieve system(2019-01-01); The aim of this study is to apply a rotating sieve system to the parboiling process for parboiled rice production. The parboiling time and rotation speed were the main production factors affecting the quality attributes of the parboiled rice, including the degree of starch gelatinization (DG), fissure percentage, head rice yield (HRY), white belly, and color. The results showed that the parboiling process with a rotating sieve can decrease the parboiling time required to provide an even quality of parboiled rice. The parboiling time for an even quality of parboiled rice was 5 min at rotation speeds of 10 and 15 rpm, while the parboiling time at a rotation speed of 5 rpm was 10 min. These times were shorter than that with a fixed sieve (15 min). Moreover, the parboiling process using a rotating sieve system provided better qualities of parboiled rice than that using the fixed sieve system, including higher DG and HRY and lower fissure and whiteness percentages. Additionally, the values of DG and HRY were increased with increasing parboiling time. In contrast, the fissure and whiteness percentages of the parboiled rice decreased. However, the quality of the parboiled rice was not dependent on the rotation speed. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Preparation and characterization of fuel briquettes made from dual agricultural waste: Cashew nut shells and areca nuts(2020-05-20); The purpose of this work was fuel briquettes production from cashew nut shells (CNS) and areca nut shells (ANS) with the operating parameters of the compressed screw speed (70 and 90 rpm), the mixture of CNS, ANS, and cassava flour (binder) in the unit by weight percent (6 proportions), and the CNS size (small and large). The effects of these parameters on the production rate, mechanical properties (hardness and porosity), and fuel properties, i.e., moisture content (MC), calorific value (CV), volatile matter content (VM), ash content (AC), fixed carbon content (FC), and combustion rate (CR), were investigated. The fuel application for cooking was evaluated with the flame temperature (FT), water boiling test (WBT), thermal efficiency (TE), and greenhouse gases (GHG) emission. Experimental results showed that the speed had the most effect on the production rate, while the CR got the least effect from all parameters compared to the other properties. The briquette should be produced using small CNS with the mixture of CNS 65%, ANS 25% and, cassava flour 10% (by weight) at speed of 90 rpm which provided the high production rate together with satisfying fuel properties, unless the CR was low. The fuel briquette showed the potential for cooking in acceptable level with the low GHG emission. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Charcoal briquette production from waste in the coffee production process using hydrothermal and torrefaction techniques: A comparative study with carbonization technique(2022-10-20); ; ; This research aimed to study charcoal briquette production from coffee production waste, i.e., coffee parchment (CP) and coffee cherry pulp (CCP). The carbonization technique (CT) was studied in five mixtures (CP and CCP ≈ 0–90%) and three pressures (1000–1600 psi) to determine the appropriate conditions. The torrefaction technique (TT) and hydrothermal technique (HT) were subsequently performed under proper conditions from the CT to investigate further the fit temperatures (200–260 °C) and reaction times (40–120 min). The fuel characteristics were examined regarding the calorific value (CV), proximate and ultimate analyses, mechanical properties, and utilization properties. The results demonstrated the notable influence of interaction between the mixture and pressure factors and individual mixture on the fuel properties, whereas personal pressure have an insignificant effect. The ratio of CP ≈ 90% and binder ≈10% at a pressure of 1600 psi in the CT prepared appropriate fuel properties (calorific value ≈ 27 MJ/kg, fixed carbon content ≈ 65%). Interestingly, almost all conditions of the TT and HT provided greenhouse gas emissions lower than the CT. The TT and HT at 260 °C for 120 min provided high calorific values (25–26 MJ/kg) with other fuel characteristics in the acceptable standard, except for the fixed carbon content.
