Task-specific ionic liquid-assisted extraction and separation of astaxanthin from shrimp waste

Novel astaxanthin extraction from Haematococcus pluvialis using cell permeabilising ionic liquids

“…Astaxanthin accumulates in these cells as a mixture of monoand di-esters under growth limiting conditions [4][5][6] and can constitute up to 1-5% of the alga's dry weight 7,8 . Task specific ILs in combination with ultrasonication has been used to extract astaxanthin from shrimp waste 17 . In aquaculture, H. pluvialis is used as feed supplement for improving the colour of salmons and crustacean species to obtain a better market price for these products.…”

Pre-treatment and extraction techniques for recovery of added value compounds from wastes throughout the agri-food chain

“…306 This limitation can be overcome by using tailored ILs to reach high-selectivity extraction. In this review, the main achievements in the processing of food waste, namely crustacean shells, [307][308][309] citrus and potato peels, [310][311][312] poultry feathers 313,314 and peanut hulls, are discussed. 315,316 In these works, ILs are used as either pretreatment or as an extraction agent to obtain value-added biomolecules in a more sustainable manner.…”

Nitrite Ionic Liquids (IL‐ONO and [bmim]NO2) as Effective Nitrosonium Sources for the Synthesis of α‐Oximinoketones under Mild Heterogeneous Conditions

“…TSILs have been increasingly used in synthetic organic chemistry. [28][29][30][31][32] In this work we wish to report the two nitrite functionalized ionic liquids as new reagents for the nitrosation of ketons and β-diketones (Figure 1). …”
