“…Increasing temperature increased vapor pressure of solute from the material. Thus, the solubility of extraction yield and curcumin content increased [19,20]. However, when higher temperature was applied in extraction, extraction yield and curcumin content in extract may decrease because temperature might be continue to increase by the high intensity of ultrasound.…”

“…The extraction process was carried out at various values of the operating condition: temperature (40, 50, 60 o C), pressure (15,20,25 MPa), CO2 flow rate (2, 3, 4 mL/min), and colsolvent (10, 15, 20%). In order to study the dynamic of extraction process, extract time was performed at 30, 60, 90, 120 min.…”

Abstract. Recently, ultrasound assisted supercritical fluid is used for extraction the valuable compounds from a number of plant materials as an alternative to conventional method because it can enhance the extraction rate and yield. Curcumin is an important component of turmeric (Curcuma longa L.) with many useful functions to human health. The objective of this study is using ultrasonic assisted supercritical carbon dioxide (USC-CO2) to extract curcumin from turmeric and compared to conventional method. The effect of operating conditions on extraction, including temperature (40-60 o C), pressure (15-25 MPa), extraction time (30-120 min), CO2 flow rate (2-4 mL/min) and percentage of cosolvent (10-20% v/v) were also studied. The result shows that the high extraction yield of 7.17% w/w and curcumin content of 1.69% w/w were achieved at temperature of 50 o C, pressure of 25 MPa, extraction time of 90 min, CO2 flow rate of 3 mL/min with 10% cosolvent. Compared to conventional method, USC-CO2 could provide higher curcumin content in extraction yield in a shorter extraction time. Scanning electron microscopy (SEM), thermal gravity (TG), and fourier transform infrared spectroscopy (FTIR) was used to analyse turmeric undergoing USC-CO2 and conventional extraction and showed that ultrasound could break down the cell walls and remove some functional groups from plant materials, resulting an increase the selectivity of compounds in extraction yield.

The current work concerns solid liquid extraction from red and white grapes skin and the rosehip (Rosa canina) to obtain extracts with a high phenolic content. Extracts have been acquired using conventional extraction techniques and extraction with supercritical fluids (SCFs). The effect of extraction method and experimental parameters (time, pressure, temperature and solvent mixture) mostly believed to affect the extraction process was undertaken. The quantitative parameters studied are: total phenolic compounds, proanthocyanin content, and the phenolic constituent profile. The qualitative parameter analyzed is antioxidant capacity. The results demonstrate that the contents of the major constituents significantly varied among the different types of materials. The highest content of total phenolics was determined in the extract from the white grape skin, macerated with MeOH (26.7 mg GA/g extract), and similar, 25.6 mg GA/g extract in the MeOH extract attained by Soxhlet. Ellagic acid (0.650 mg/100 g extract), catechin (0.164 mg/100 g extract), gallic acid (0.133 mg/100 g extract) as well as caffeic acid (0.038 mg/100 g extract) are the major compounds present in the rosehip extracts attained by maceration using MeOH as solvent. The presence of epictechin, hesperidin/neohesperidin, rutin, and chlorogenic acid was also confirmed. Aspects of each type of processing were correlated with the chemistry of the material. The obtained extracts could be used as natural bioactive compounds in several industrial applications.

“…Because of CO 2 's ability to dissolve lipophilic substances, 38 the extraction of bioactive or high-value compounds using supercritical CO 2 (scCO 2 ) is one of the most common approaches used for the valorization and fractionation of biomass. 9,[39][40][41][42][43][44][45] This approach is notably used extensively in industry especially for the production of food additives or medicinal products due to CO 2 's non-toxic nature. 46 Within bioenergy applications, the targeted compounds during extractions have mainly been lipids, waxes, proteins, lignin and phenolic compounds for the production of biodiesel, fatty acids, amino acids, power/heat, aromatic compounds and other fine chemicals.…”

Biomass is an attractive source of renewable carbon-based fuels and chemicals and their production is envisaged within the framework of integrated biorefineries. Multiple research efforts to make biorefineries more economically competitive and sustainable are ongoing. In this context the use of high-pressure CO2 and CO2/H2O mixtures for biomass conversion is especially attractive. These mixtures are cheap, renewable, environmentally benign and allow tuning of various processing parameters by varying temperature, pressure and CO2 loading. This chapter presents a broad introduction of the principal processes and conversion routes being considered within biorefineries, and how high-pressure CO2 and CO2/H2O mixtures could help address certain challenges associated with biomass conversion. Some of the principle advantages associated with high-pressure CO2 and CO2/H2O mixtures that we highlight here are their abilities to act as green substitutes for unsustainable solvents, to enhance acid-catalysed reaction rates by in situ carbonic acid formation, to reduce mass transfer-limitations, and to increase access to substrates and catalysts. We discuss these advantages in the context of the trade-offs associated with implementing large-scale high-pressure systems including safety concerns and increased capital costs. With this introduction, we highlight both the principal benefits and challenges associated with the use of high-pressure CO2 and CO2/H2O mixtures, which are further detailed in subsequent chapters.
