Enzyme-assisted extraction of κ/ι-hybrid carrageenan from Mastocarpus stellatus for obtaining bioactive ingredients and their application for edible active film development

Abstract

14Two hydrolysates were obtained from dried Mastocarpus stellatus using alcalase. Phenolic 15 content was partially removed from one of them. The phenolic-partially-removed hydrolysate (H) 16was found to be a potent Angiotensin-I converting enzyme (ACE) inhibitor. However, the

Sulfated Seaweed Polysaccharides as Multifunctional Materials in Drug Delivery Applications

“…Although the process is much shorter and cheaper than the first one, its purity is necessarily lower [ 2 , 28 , 29 , 30 , 31 ]. Other methods can be found in the literature such as enzyme-treated or fungal-treated extractions [ 32 , 33 , 34 , 35 ]. Enzymatic extraction, for example, can enable the production of specific gelation properties, since the physicochemical properties of carrageenan depend on the composition of the polysaccharide and on the number of counterions [ 36 ].…”

A review of extractions of seaweed hydrocolloids: Properties and applications

“…However, only a limited number of studies regarding the application of EAE method in the extraction of seaweed hydrocolloids back to date (Table 5). Previous studies have shown that high yield of carrageenan with good gelling properties was obtained from popular red seaweed species Eucheuma cotonii and false Irish moss with added values of polyphenols for latter species [91,92]. It is believed that, EAE not only significantly improves extraction yield of bioactive compounds but at the same time maximizes their antioxidant and antiviral activities and this in fact not happening in conventional extraction method unless they are optimized [93].…”

“…Higher carrageenan (45%) obtained with EAE compared with conventional method (37.5%) from red seaweed Eucheuma cottonii [91] Carrageenan which shown good gelling properties was successfully obtained from false Irish Moss Mastocarpus stellatus [92] Bioactive derivatives were efficiently extracted from Chondrus crispus and Codium fragile with solvent free [93] Ultrasound-assisted extraction (UAE)…”

Carrageenan: Drug Delivery Systems and Other Biomedical Applications

“…Other more complex methods include extraction using enzyme [ 46 , 47 ], or fungal [ 48 ], extraction with deep eutectic solvents (DESs) [ 49 , 50 ]. Microwave-assisted extraction, ultrasound-assisted extraction, reactive extrusion, and photobleaching processes have also been reported in recent years [ 51 , 52 , 53 , 54 ].…”
