  • Can lutein be extracted from marigold flower petals?
  • Yes, lutein can be extracted from marigold flower petals. Manzoor et al. (2022) demonstrated a green extraction process for lutein from marigold petals, which improved the oxidative stability of sunflower oil.
  • Can microemulsion extract lutein from Marigold?
  • Soleiman Abbasi has proposed a new method for lutein extraction: food-grade microemulsion containing soy lecithin and sunflower oil, and then the effects of ultrasound and enzymatic hydrolysis on the extraction of lutein from marigold by microemulsion were investigated ( Jalali-Jivan and Abbasi, 2020, Jalali-Jivan et al., 2019 ).
  • Do different ratios of marigold petal powder to microemulsion affect lutein extraction efficiency?
  • Effects of different ratios of marigold petal powder to microemulsion on the extraction efficiency of lutein. Note: Different superscripts in the same line represent significant differences ( P <?0.05). To extract the remaining lutein in the residue, a new microemulsion was added for re-extraction after the extraction was completed.
  • Which surfactant extracts the most lutein from marigold petals powder?
  • Preliminary screenings for extraction of lutein from marigold petals powder. The results attained manifest that the extraction of lutein by non-ionic surfactant solutions, specially plurafac LF 120, gave the most lutein (8.197 ± 0.046 mg/g) among all surfactants studied.
  • Can hexane be used to extract lutein from marigold petals?
  • Marigold petals are the primary industrial source of lutein. An efficient green process described for isolating high purity lutein from marigold petals. The process does not require recrystallization for further purification of free lutein. 2-MeTHF appears as a potential alternative solvent to hexane for lutein extraction.
  • Can edible oil extract lutein from Chinese marigolds?
  • Yes, edible oil can be used as a co-solvent for the supercritical fluid extraction method to recover lutein from Chinese marigolds. For instance, Gao et al. (2009, 2010) and Ma et al. (2008) have successfully extracted lutein using this method with edible oils like soyabean oil.
