“…A particular challenge is that hydrolysis rates and sugar yields depend on the characteristics of the residues, composition and structure of the cell wall, and the type of the monosaccharides present in the feed. As a result, each raw material must be studied individually, each new feed representing a new set of technological challenges (Prado et al, 2014).…”

Biofuel Research Journal 14 (2017) HIGHLIGHTSØAdvances of research trends in development of subcritical and supercritical water processes technologies are reviewed.Essential aspects of sub-and supercritical water applied to extraction, hydrolysis, carbonization and gasification processes are discussed. ØEquipment design, process parameters, and types of biomass used for sub-and supercritical water process are presented. ØBioactive compounds, reducing sugars, hydrogen, biodiesel, and hydrothermal char are the final products of sub-and supercritical water processes. This review summarizes the recent essential aspects of subcritical and supercritical water technology applied to the extraction, hydrolysis, carbonization, and gasification processes. These are clean and fast technologies which do not need pretreatment, require less reaction time, generate less corrosion and residues, do not use toxic solvents, and reduce the synthesis of degradation byproducts. The equipment design, process parameters, and types of biomass used for subcritical and supercritical water process are presented. The benefits of catalysis to improve process efficiency are addressed. Bioactive compounds, reducing sugars, hydrogen, biodiesel, and hydrothermal char are the final products of subcritical and supercritical water processes. The present review also revisits advances of the research trends in the development of subcritical and supercritical water process technologies. GRAPHICAL ABSTRACT ARTICLE INFO ABSTRACT

“…Carotenoids are substances with potent biological and antioxidant activities and are considered precursors for the synthesis of vitamin A. The residues from palm oil extraction are usually burned as fuel despite containing a significant amount of remaining oil and can be a great source of lignocellulosic material [19,32].…”

This work involves the residues of three plant species used in industry: Brazilian ginseng (Pfaffia glomerata), palm (Elaeis guineensis) and annatto (Bixa orellana L.). The studied plant residues come from oil and biocompounds extraction: Soxhlet extraction (SE), Pressurized liquid extraction (PLE) and Supercritical fluid extraction (SFE). The effects of these extraction processes on the structures of plant matrices were observed using scanning electron microscopy (SEM). Plant residues were subjected to acid hydrolysis. The hydrolysis process was conducted using a 0.5 L reactor at atmospheric pressure and the solvent at boiling temperature. Brazilian ginseng was hydrolyzed in hydrochloric acid solution (0.5, 2.5 and 5.0%, v/v) for 60 min. Palm pressed fiber and annatto were hydrolyzed in sulfuric acid solution (1.5 and 3.0%, v/v) for 90 min. Sugars produced by the hydrolysis were quantified and interpreted as Reducing sugars (RS) (g glucose/100 g raw material) and Total reducing sugars (TRS) (g sucrose/100 g raw material) by a spectrophotometric method. The results observed by SEM showed that the extraction treatments modified the vegetable matrix with respect to its structure and component ratio. The acid hydrolysis process of each vegetable matrix showed different reaction kinetics. The availability and source of the sugar polymers and the acid concentration were variables that affected the hydrolysis reaction.

“…Apart from the examples above, SWE has also been used to extract many other compounds from various plants sources such as pectin [44], oil [47], reducing sugars [48], resorcinol and chavibetol [50], mannitol [51], asiatic acid [52], mangiferin [53], and carotenoids [54]. All these compounds have beneficial properties that can be applied in the food and pharmaceutical industries.…”

Plants and algae are the main sources of natural bioactive compounds used in the food and pharmaceutical industries. It is very important to achieve an efficient and safe technique to recover bioactive compounds while maintaining their quality and properties. Subcritical water extraction is the most promising engineering approach that offers an environmentally friendly technique for extracting various compounds from plants and algae. Application of pressurized water and high temperature in subcritical phase is able to modify the dielectric constant and polarity of the solvent which then contributes to a better extraction process. The technique improves the mass transfer rate and preserves the biological potency of the extracts. This article reviews current studies on the extraction of bioactive compounds from various species of plants and algae using the subcritical water technique and discusses its effects and benefits for the food and pharmaceutical industries.
