“…Similar values were reported for total carotenoids by Durante et al [34], who obtained values of 463.1 and 446.2 mg/100 g for pumpkin and tomato oleoresins obtained by supercritical extraction. Devani et al [22] obtained a high quality of onion oleoresins with a yield of 1012 g/100 g of powder, containing 31 g sulphur/kg oleoresin.…”

“…Supercritical fluid extraction, as an alternative to the conventional techniques [15], has emerged in recent decades for the extraction and fractionation of oleoresin from different matrices. For example, supercritical CO 2 has been used to extract food-grade oleoresins from different plant matrices, including tomato [16][17][18], pumpkin [19,20], watermelon [18], sweet potato tubers [21], rotten onion waste [22], wheat bran [23], spices [14], leaf sea buckthorn [24] and sea buckthorn berries [25], as well as gac [18], or for fractionation of the oleoresins from rosemary ethanolic extract [26].…”

Oleoresin supercritical extracts from sea buckthorn were microencapsulated in whey proteins isolate and casein, in two states: native (N) and cross-linked mediated by transglutaminase (TG). The encapsulation efficiency showed values higher than 92% for total carotenoids and lycopene. Phytochemicals content was 352.90 ± 1.02 mg/g dry weight (DW) for total carotenoids in TG and 302.98 ± 2.30 mg/g DW in N, with antioxidant activity of 703.13 ± 23.60 mMol Trolox/g DW and 608.74 ± 7.12 mMol Trolox/g DW, respectively. Both powders had an inhibitory effect on α-glucosidase, of about 40% for N and 35% for TG. The presence of spherosomes was highlighted, with sizes ranging between 15.23–73.41 µm and an agglutination tendency in N, and lower sizes, up to 35 µm in TG. The in vitro digestibility revealed a prolonged release in an intestinal environment, up to 65% for TG. Moisture sorption isotherms were studied at 20 °C and the shape of curves corresponds to sigmoidal type II model. The presence of cross-linked mediated aggregates in TG powders improved stability and flowability. Our results can be used as evidence that cross-linked aggregates mediated by transglutaminase applied for microencapsulation of oleoresins have the potential to become new delivery systems, for carotenoids and lycopene, being valuable in terms of their attractive color and biological and bioaccessibility properties.

“…Extensive research has also been conducted on SFE from onion by-products. Devani et al evaluated the effects of pressure , temperature (50-90 °C), time (30-150 min), and particle size (0.4-1.2 mm) on oleoresin extraction yield, sulfur content, and pyruvate content from rotten onion waste through a central composite rotatable design [109]. Under optimized extraction conditions (40 MPa, 80 °C, particle size 0.53 mm for 60 min) 1.012% oleoresin, 31 g of sulfur/kg of oleoresin, and 10.41 μ mol pyruvate/g fresh weight of onion were recovered.…”

The Application of Supercritical Fluids Technology to Recover Healthy Valuable Compounds from Marine and Agricultural Food Processing By-Products: A Review

et al. 2021

Food by-products contain a remarkable source of bioactive molecules with many benefits for humans; therefore, their exploitation can be an excellent opportunity for the food sector. Moreover, the revalorization of these by-products to produce value-added compounds is considered pivotal for sustainable growth based on a circular economy. Traditional extraction technologies have several drawbacks mainly related to the consumption of hazardous organic solvents, and the high temperatures maintained for long extraction periods which cause the degradation of thermolabile compounds as well as a low extraction efficiency of desired compounds. In this context, supercritical fluid extraction (SFE) has been explored as a suitable green technology for the recovery of a broad range of bioactive compounds from different types of agri-food wastes. This review describes the working principle and development of SFE technology to valorize by-products from different origin (marine, fruit, vegetable, nuts, and other plants). In addition, the potential effects of the extracted active substances on human health were also approached.

“…Compared to other conventional methods, SFE has a lower solvent recovery, thermal degradation of molecules and extraction time [ 25 ]. However, during the extraction of VOCs from aromatic plant matrices, a series of fractions characterized by VOCs mixed with polyphenolic compounds and lipophilic compounds are produced [ 26 ]. These side fractions, not reaching the quality standards of traditional OEs, are considered waste and represent an economic problem for the company that produces them.…”

Modulation of Antioxidant Defense in Farmed Rainbow Trout (Oncorhynchus mykiss) Fed with a Diet Supplemented by the Waste Derived from the Supercritical Fluid Extraction of Basil (Ocimum basilicum)

Phytotherapy is based on the use of plants to prevent or treat human and animal diseases. Recently, the use of essential oils and polyphenol-enriched extracts is also rapidly increasing in the aquaculture sector as a means of greater industrial and environmental sustainability. Previous studies assessed the antibacterial and antiparasitic effects of these bioactive compounds on fish. However, studies on the modulation of oxidative stress biomarkers are still scant to date. Thus, in this study, the modulation of antioxidant defense against oxidative stress exerted by fish diets supplemented with a basil supercritical extract (F1-BEO) was assessed in rainbow trout Oncorhynchus mykiss. The F1-BEO extracted with supercritical fluid extraction was added to the commercial feed flour (0.5, 1, 2, 3% w/w) and mixed with fish oil to obtain a suitable compound for pellet preparation. Fish were fed for 30 days. The levels of stress biomarkers such as superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase, glutathione reductase, glyoxalase I, glyoxalase II, lactate dehydrogenase, glutathione and malondialdehyde showed a boost in the antioxidant pathway in fish fed with a 0.5% F1-BEO-supplemented diet. Higher F1-BEO supplementation led to a failure of activity of several enzymes and the depletion of glutathione levels. Malondialdehyde concentration suggests a sufficient oxidative stress defense against lipid peroxidation in all experimental groups, except for a 3% F1-BEO-supplemented diet (liver 168.87 ± 38.79 nmol/mg prot; kidney 146.86 ± 23.28 nmol/mg prot), compared to control (liver 127.76 ± 18.15 nmol/mg prot; kidney 98.68 ± 15.65 nmol/mg prot). Our results suggest supplementing F1-BEO in fish diets up to 0.5% to avoid potential oxidative pressure in farmed trout.
