“…However, other reports aiming to produce extracts rich in soluble sugars from fungi Grifola frondosa obtained high yields of total sugars using a HAE at 121 °C [27]. Moreover, previous reports aiming to achieve high yields of glucans from fungi and cereals reported variable yields and HAE conditions [28,29,30,31].…”

Fucose sulphated polysaccharides (FSPs) and glucans have recently attracted the attention of the scientific community due to their wide range of biological activities. Both polysaccharides should ideally be selectively extracted using innovative technologies with high extraction efficiency. This study aims to: (1) Optimise the extraction variables used in hydrothermal-assisted extraction (HAE) to obtain high yields of FSPs, total glucans, and antioxidants from Laminaria hyperborea; (2) to apply these optimised protocols to other brown macroalgae; and (3) to explore the application of ultrasound and thermal technologies to increase the recovery of polysaccharides from the residual biomass. Box-Behnken design (three-factor, four-levels) was employed to optimise the HAE variables, and principal component analysis was used to evaluate the recovery of polysaccharides from the residual biomass. The optimal HAE conditions were 120 °C, 80.9 min, and 12.02 mL/g macroalgae from L. hyperborea. The best sequential application of ultrasound and thermal treatment achieved an additional 2971.7 ± 61.9 mg fucose/100 g dried macroalgal residue (dmr) from Ascophyllum nodosum and 908.0 ± 51.4 mg total glucans/100 g dmr from L. hyperborea macroalgal residues.

The aim of this study was to investigate the effect of material type (artichoke leave, lemon peel, flaxseed meal), extraction temperature (50, 100, 120, 140, 160, 180, 200 °C) and static extraction time (5, 15, 30, 45 min) on 5-hydroxymethylfurfural (5-HMF) formation during subcritical water extraction. 5-HMF content of artichoke leave and lemon peel extracts increased 7.2 and 26.1 times with the rise of extraction temperature from 160 to 180 °C for 5 min during subcritical water extraction, respectively. Besides, 5-HMF content of artichoke leave, lemon peel and flaxseed meal extracts increased 1.4, 2.0 and 4.5 times as static extraction time increased from 15 to 45 min at 180 °C during subcritical water extraction, respectively. The highest 5-HMF content of artichoke leave and lemon peel extracts were obtained as 58.83 and 231.21 mg/L at 180 °C and 45 min, respectively. However, for flaxseed meal, the highest 5-HMF content (222.94 mg/L) was obtained at 200 °C and 15 min during subcritical water extraction.

“…Subcritical water can be obtained by increasing water temperature from 100 °C (boiling point of water) to 374 °C (critical point of water) and adjusting the pressure to ensure that water retains a liquid state. Under such conditions, the physical and chemical properties of water are significantly different [3][4][5][6][7][8]. For example, the ε value of water at 250 °C is approximately 27, which is similar to those of methanol (ε = 33) and ethanol (ε = 24) at 25 °C.…”

Subcritical water, which is an effective solvent for polar and nonpolar substances, has been used to extract numerous natural ingredients. In this study, subcritical water was used to extract bioactive substances from apple peel in a batch process in the temperature range of 100–175 °C for 5–60 min. The Fourier-transform infrared spectroscopy results revealed that phenolic compounds were released from apple peel in the aforementioned temperature range. The ultraviolet–visible spectra of the liquid products at 280 nm revealed the high content of phenolic compounds in the extracts. The high-performance liquid chromatography results demonstrated that the yield of procyanidin B2 was approximately 2.28 mg/g of dried apple peel when extraction was performed at 150 °C for 15 min.
