“…This is, for instance, the case of the extraction of volatiles and essential oils that are more efficiently extracted with solvents such as nhexane [82][83][84]. However, as it has been already mentioned, one of the most important trends in this field is based on the search and application of new environmentally green and food-grade solvents.…”

ABSTRACT.The improvement of sample preparation and extraction techniques for natural bioactive compounds determinations is of great importance nowadays. New concepts are being introduced in this field, not only related to enhancement of extraction efficiencies but also related to environmental impact. This evolution towards Green Chemistry is pushing to new extraction and sample preparation processes that should be faster, more reproducible and more environmentally friendly. In this context, compressed fluidsbased sample preparation techniques (such as supercritical fluid extraction and pressurized liquid extraction) are demonstrating good capabilities. In this review, an updated knowledge on the techniques will be presented together with the main technical developments and the most notable recent applications for the extraction of bioactive compounds.Keywords: bioactive compounds, natural samples, plants, agricultural by-products, pressurized liquid extraction, supercritical fluid extraction, subcritical water extraction Abbreviations: ASE, accelerated solvent extraction; DHA, docosahexaenoic acid; EAE, enzyme-assisted extraction; EPA, eicosapentaenoic acid; IL, ionic liquids; MIP, molecular imprinted polymers; PFE, pressurized fluid extraction; PHSE, pressurized hot solvent extraction; PHWE, pressurized hot water extraction; PLE, pressurized liquid extraction; PLPW, pressurized low polarity water extraction; n-3 PUFA, n-3 polyunsaturated fatty acid; RAM, restricted access media; scCO2, supercritical CO2; SFE, supercritical fluid extraction; SHWE, superheated water extraction; SPE, solid Published in TrAC.

“…A second order polynomial equation for each response was generated based on the data obtained from experiments, and then analyzed through the analysis of variance (ANOVA) test in order to evaluate the model. A good model should have a significant p value, where p < 0.05, an insignificant lack of fit test p value, where p >0.05, and an R 2 value, which should be closer to 1 or at least 0.80 to fit into the model (Zaibunnisa et al 2009). A summary of the results obtained from the ANOVA test for the OPB fibers in the response surface quadratic model are shown in Table 4.…”

Optimization of Superheated Steam Treatment to Improve Surface Modification of Oil Palm Biomass Fiber

et al. 2016

Superheated steam (SHS) pretreatment is an effective method for hemicellulose removal from oil palm biomass (OPB) fiber, which leads to the surface modification of the fiber. However, the current SHS pretreatment is conducted at a high temperature and has a long retention time, which causes the removal of cellulose, which is an important component for biocomposite production. This study was conducted to optimize the SHS treatment temperature and retention time so that hemicellulose but not cellulose was removed. Three types of OPB fibers were used: oil palm mesocarp fiber (OPMF), oil palm empty fruit bunch (OPEFB), and oil palm frond (OPF). The chemical composition data was analyzed using a type of response surface methodology (RSM), i.e., central composite design (CCD). The optimal SHS treatment temperature and retention time were 265 °C/5 min, 280 °C/5 min, and 300 °C/9 min for OPMF, OPEFB, and OPF, respectively. The removal of hemicellulose at these temperatures was in the range of 60% to 70%, while the cellulose degradation was maintained below 5%. Statistical analysis showed that the optimal SHS treatment time can be shortened to 5 min to 9 min, which is 18 to 20 times shorter than previously reported methods.

“…Fresh turmeric rhizomes were cleaned with water and sliced about 3 mm thick and air-dried at room temperature until the moisture content reached to 10 -15 % as reported by Zaibunnisa et al [9]. Samples were then ground and sieved to 2 mm size and were put into sealed plastic bags at chilled temperature until further analysis.…”

Turmeric is one of the prominently use herbal plants due to its diverse beneficial effects especially in Indian medicine. The rhizome part of the turmeric contains valuable compounds which have been said to owe its antimicrobial effects, anti-cancer, anti-inflammatory and enhance wound healing. Due to its short-life span and perishable properties, the conversion of the rhizome into turmeric extract is desirable. Several methods have been used for extraction such as Soxhlet extraction and pressurized liquid extraction (PLE). However, these techniques are tedious, laborious, time consuming and involves the usage of toxic organic solvent, of which safeness of the end product is doubtful. In this study, a rapid, reliable and green extraction method of supercritical fluid extraction (SFE) and ultrasonic assisted extraction (UAE) were used. SFE without modifier has resulted in 0.0006 mg/100 g of curcuminoids concentration and 5.62 % of yield (dry weight basis). UAE using ethanol was able to produce significantly the highest yield (6.40 %, dry weight basis) and the highest curcuminoids concentration (0.1020 mg/100 g). However, SFE was able to produce extract that contain significantly higher major volatile compounds; tumerone, ar-turmerone and curlone. Therefore, this study proves that both extraction methods were able to produce high quality turmeric extract.Keywords: Supercritical fluid extraction, Ultrasonic assisted extraction, percentage yield, curcuminoids, volatile compounds Abstrak Kunyit merupakan tumbuhan herba yang terkenal disebabkan kebaikannya yang pelbagai terutamanya dalam perubatan masyarakat India. Bahagian rizom kunyit mengandungi sebatian berkhasiat yang dipercayai mempunyai kesan antimikrobial, anti-kanser, anti-keradangan dan juga mempercepatkan kadar penyembuhan luka. Disebabkan kitar hidup yang singkat dan ciri mudah rosak yang terdapat pada kunyit, maka penukaran rizom kunyit kepada ekstrak kunyit adalah amat wajar. Beberapa kaedah pengekstrakan telah digunakan seperti pengekstrakan Soxhlet dan pengekstrakan cecair bertekanan (PLE). Bagaimanapun, kaedah-kaedah tersebut amat rumit, sukar, mengambil masa yang lama serta melibatkan penggunaan pelarut organik bertoksik yang menyebabkan keraguan terhadap tahap keselamatan produk iaitu ekstrak kunyit. Di dalam kajian ini, kaedah pengekstrakan yang pantas, dipercayai serta mesra alam iaitu pengekstrakan cecair supergenting (SFE) dan pengekstrakan ultrasonik berbantu (UAE) telah digunakan. SFE tanpa bahan pengubahsuai telah menghasilkan 0.0006 mg/100 g kepekatan kurkuminoids dan 5.62 % hasil ekstrak kunyit (berdasarkan berat kering). UAE menggunakan etanol telah menghasilkan hasil ekstrak yang ketara tinggi (6.40 %, berdasarkan berat kering) dan nilai kepekatan kurkuminoids tertinggi iaitu 0.1020 mg/100 g. Walaubagaimanapun, SFE telah menghasilkan ekstrak yang mengandungi sebatian meruap yang
