Carvacrol-loaded microcapsules were developed based on coacervation complexes of whey protein isolate (WPI) and high methoxyl pectin (HMP), followed by crosslinking with tannic acid (TA). Optimal pH and WPI-HMP ratios for complex coacervation were found to be 4.1 and 5:1, resp. Coacervation complexes were used to encapsulate carvacrol. Optimum conditions for achieving morphol. and encapsulation efficiency were found for wall materials with a concentration of 2% (w/v), a wall/core ratio of 1:2 (w: w), and a homogenization speed of 15,000 rpm. The optimized formulation of microcapsules has an encapsulation efficiency of 77.48 ± 0.03% for carvacrol and a size of 1.08μm. The addition of tannic acid (TA) decreased particle size and had no other influence on the morphol. properties of microcapsules. Addnl., Fourier transform IR spectroscopy (FTIR) indicated that coacervates were formed through the electrostatic interactions between WPI and HMP and the main force between TA and coacervates is hydrogen bonding. The addition of HMP to WPI and the presence of TA both decreased the content of tryptophan residues. Carvacrol microcapsules crosslinked with TA demonstrated better stability and antioxidant properties, showing potential for encapsulation of bioactive substances. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Application In Synthesis of 5-Isopropyl-2-methylphenol).
5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Application In Synthesis of 5-Isopropyl-2-methylphenol
