“…Pretreatment techniques like drying, crushing and grinding may be required depending on the samples. After extraction, isolation and purification are done to obtain the active compounds (Chuo et al 2020 ). Conventional extraction methods mainly include percolation, decoction, heat reflux extraction, Soxhlet extraction and maceration.…”

There is a growing demand for vegetal food having health benefits such as improving the immune system. This is due in particular to the presence of polyphenols present in small amounts in many fruits, vegetables and functional foods. Extracting polyphenols is challenging because extraction techniques should not alter food quality. Here, we review technologies for extracting polyphenolic compounds from foods. Conventional techniques include percolation, decoction, heat reflux extraction, Soxhlet extraction and maceration, whereas advanced techniques are ultrasound-assisted extraction, microwave-assisted extraction, supercritical fluid extraction, high-voltage electric discharge, pulse electric field extraction and enzyme-assisted extraction. Advanced techniques are 32-36% more efficient with approximately 15 times less energy consumption and producing higher-quality extracts. Membrane separation and encapsulation appear promising to improve the sustainability of separating polyphenolic compounds. We present kinetic models and their influence on process parameters such as solvent type, solid and solvent ratio, temperature and particle size.

“…This is because tocotrienols are heat sensitive and so can be broken down by the high operating temperature and longer extraction time employed in Soxhlet extraction (Ribeiro et al, 2019). Even though the higher temperature used will reduce solvent viscosity, it can also cause bioactive compounds to degrade, thus reducing the extraction yield (Chuo et al, 2020). In this study, the extraction time with scO 2 is relatively low (with higher efficiency of tocotrienol extraction) compared to Soxhlet extraction, which needed 8 hr (Lee et al, 2013).…”

“…Temperature and pressure are the main factors that significantly affect the density of scCO 2 , and hence its solvation power. The temperature effect is more complex, as it involves both the density of scCO 2 and the volatility of solute compounds (Chuo et al, 2020). It was found that temperature had a more pronounced effect on the recovery of tocotrienols.…”

In 2020, approximately 19.14 million tonnes of crude palm oil (CPO) was produced in Malaysia (MPOB, 2020). Typically, 4% (w/w) of CPO is in the form of palm fatty acid distillate (PFAD), which is recoverable as a by-product from the physical refining process (Estiasih & Ahmadi, 2018;Gapor Md Top, 2010). Fatty acids and glycerides are the major components (96.1%) of PFAD; these are commonly used in nonfood industries, within animal feed, laundry soap, biodiesel, and oleochemicals (Akinfalabi et al., 2019;Estiasih & Ahmadi, 2018;Gapor Md Top, 2010). Oil can be lost at various stages of the refining process. In addition, oil can be trapped in the by-product during palm oil milling. Consequently, vitamin E (0.48%), sterols (0.37%), squalene (0.76%), and volatile substances (0.71%) are valuable minor compo-

“…Some structural examples are shown in Figure 16. The extraction of bioactive molecules from agro-industrial wastes has drawn increasing attention (Chuo et al, 2020;Flourat et al, 2020). The recovery of SinA and derivatives mainly relies on solid-liquid extraction where water/alcohol mixtures are often used as the extraction solvent (Prapakornwiriya and Diosady, 2014;Flourat et al, 2019;Laguna et al, 2019;Reungoat et al, 2020).…”

Sinapic Acid and Sinapate Esters in Brassica: Innate Accumulation, Biosynthesis, Accessibility via Chemical Synthesis or Recovery From Biomass, and Biological Activities

Sinapic acid (SinA) and corresponding esters are secondary metabolites abundantly found in plants of Brassica family. Belonging to the family of p-hydroxycinnamic acids, SinA and its esters analogues are present in different plant parts and involved in multiple biological processes in planta. Moreover, these metabolites are also found in relatively large quantities in agro-industrial wastes. Nowadays, these metabolites are increasingly drawing attention due to their bioactivities which include antioxidant, anti-microbial, anti-cancer and UV filtering activities. As a result, these metabolites find applications in pharmaceutical, cosmetic and food industries. In this context, this article reviews innate occurrence, biosynthesis, accessibility via chemical synthesis or direct extraction from agro-industrial wastes. Biological activities of SinA and its main corresponding esters will also be discussed.
