Studies of iso-alpha-acids: analysis, purification, and stability. Khatib, Alfi

To remove the β-CD, two methods were applied, UF using a membrane with a cut off of 1000 Da or taking the solution to dryness and re-dissolving it in ethyl acetate. Of these,

In order to release the trans-IAAs from the β-CD complex, the precipitate was treated with different organic solvents: ethanol, ethyl acetate, dichloromethane,

Isolation of individual α-acids (cohumulone, humulone, and adhumulone) from a supercritical carbon dioxide hop extract was performed by centrifugal partitioning

Although we did not determine the structure of the degradation products observed in the HPLC chromatograms, the stability tests still can be performed by measuring

Score plot of principal component analysis of 2-butanol extract of beer using PC2 vs PC3 (A) and loading plot (B) based on aromatic region of projected J-resolved NMR spectra (δ 6.0

The pure individual iso-α-acids are required as standard compounds for analysis and also needed in brewery research when studying the parameters which affect

Een ander resultaat van deze studie is dat de individuele iso-α-zuren nu kunnen worden geproduceerd uit de zuivere α-zuren., verkregen door CPC-scheiding,
