Thus, this study highlights the use of ASPEN Plus-response surface methodology (RSM) approach to simulate and optimise the energy consumption of sterilisation process based on exergy analysis ( i.e. exergy destroyed) and chemical reaction. ASPEN Plus V8.6 was employed to simulate the sterilisation process and then optimised using RSM. The validation of simulation results with experimental results demonstrating error values of less than 5.0%. Comparison of outlet stream simulation results with mill’s data also showed deviation values less than 10.0%. These indicated that the actual values were in good agreement with model prediction. For optimisation, three variables were considered, namely pressure, steam mass flow and sterilisation time. For conventional steriliser operated at 2.8 bar, 90 min and 14 580 kg/hr steam mass flow, the exergy destroyed was 5259.3 MJ/hr. Under optimised conditions at 5 bar pressure, 70 min and 17 550 kg/ hr steam mass flow, the exergy destroyed was 3493.9 MJ/hr. In comparison to conventional conditions, the heat loss was reduced by 33.6%. This approach is considered sustainable as it could predict the performance of industrial process without impacting processing time, cost and resources consumption.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48716552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the free fatty acid content in loose fruits is undesirably high, microwave sterilisation is known to reduce it significantly. The present study enhanced microwave sterilisation using a new integrated microwave-steam method in which steam exiting the fruits during vaporisation is entrapped and used to complement the heat treatment process. The effect of this new method on the heating uniformity, drying rate, oil extraction rate, crude palm oil quality and energy consumption/cost was investigated. Results showed that up to 25.7% and 13.6% reduction in temperature non-uniformity and energy consumption/cost was achieved with MW-steam heating. Moreover, sterilisation duration was reduced by up to 11.6%. The stacked arrangement of fruits improved microwave absorption efficiency, reducing temperature non-uniformity by up to 45.0% and energy consumption by up to 19.2%. MW-steam sterilisation achieved up to a 10.5% increase in oil extraction rate. Crude palm oil with excellent hydrolytic and oxidative stability was acquired, thus, boosting oil value that can facilitate post-processing in palm oil mills.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43216578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work described the transcript and protein profiles in roots of 18 month-old oil palm seedlings that were exposed to the fungal pathogen for 12 months, following artificial inoculation at 6 month-old. Three different phenotypes were observed; control (uninoculated), asymptomatic, and symptomatic (inoculated). It was found that the transcripts from the ubiquitin-mediated proteolysis pathway were common in control and asymptomatic seedlings; while proteins involved in cellular processes, and protein and sugar metabolisms were higher in abundance in asymptomatic seedlings. The transcripts involved in carbon fixation, glycolysis/gluconeogenesis, and pyruvate metabolism together with proteins responsible for stress response were identified in symptomatic seedlings. By integrating these omics data, it was observed that symptomatic seedlings were moving towards generating and storing energy for a possible defence strategy, and at the same time emitting stress signals and responses. This was in contrast with asymptomatic seedlings where regular functions such as cellular processes and carbohydrate metabolisms were found to be active.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43987912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blends of BL and PME (BL-PMEs) were prepared with 5%, 10% and 15% of BL. The addition of BL has improved the cloud and pour points by 7°C for 15BL-PME. As compared to ASTM D6751 and EN14214 specifications for biodiesel, BL-PMEs revealed properties within the specifications in terms of acid value, flash point, kinematic viscosity (40°C), and oxidative stability. The addition of BL up to 15% increased the acid value and decreased the flash point and kinematic viscosity. The oxidative stability increased slightly upon the addition of BL. The calorific value of BL-PMEs decreased with an increase in BL volume. Up to 10% BL, the calorific value is >35 MJ kg –1 . Besides, BL is highly miscible with PME and no phase separation was observed. The present work suggested that BL has potential as a bio-based fuel blend compound for biodiesel.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43095772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selected physicochemical analyses, namely fatty acid composition, crystal structure and shear viscosity were conducted for OSW selection to be used in a product that is spreadable at low temperature (5°C-10°C) and phase separation does not occur at high temperature (40°C-45°C). Mono-unsaturated and poly-unsaturated as well as saturated fatty acids of all OSW were significantly different ( p <0.05). Crystals in OSW with SFW showed needle-like structure and fibrous, while OSW with CW was observed to be spherulitic and OSW with BW was needle-like in shape at 10°C, 25°C, 40°C and 45°C. OSW with 3.5% SFW and 3.5% CW showed dense packing at 45°C; hence, it had the potential to prevent phase separation in the end product at high temperatures. The shear viscosity of all OSW at all temperatures was below 2.0 Pa.s, in which SFW showed the highest value at 5°C, although the value was low. Therefore, based on the experimental parameters, 3.5% CW can be implied as the best structuring agent, followed by 3.5% SFW.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48267623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data were then subjected to principal component and cluster analyses. Correlation analysis among traits of E. oleifera showed a similar trend as Elaeis guineensis , and most of the characters displayed a wide range of variation. In the principal component analysis, the first four principal components (PC1-PC4) with eigenvalue of >1.0, accounted for 96.32% of the total variability, suggesting that E. oleifera accessions can be clearly differentiated using the traits studied. Cluster analysis showed that all accessions were clustered into two major groups (consisting of four sub-clusters), generally attributed to their geographical locations in Central and South America.

The result showed that the catalyst with a weight ratio of zeolite to sulfonated carbon of 1:3 (% w/w) had the highest acidic value of 10.80 mmol g –1 and was used for further esterification optimisation. FTIR and EDX analysis affirmed the existence of a sulfonated group of the composite catalysts. The 13 C NMR analysis showed that the esterification successfully produced an ester compound.
