When you swallow food, it doesn't just drop down into your stomach. Muscles contract in a wave-like motion to move the food along through the esophagus. This muscle movement is called, peristalsis, or peristaltic waves. These peristaltic waves contract behind the food bolus pushing it along the digestive tract.

Characterization and determination of the S/G ratio via Py-GC/MS of agricultural and industrial residues

Oksanka [162]

Characterization and determination of the S/G ratio via Py-GC/MS of agricultural and industrial residues.

<h3>What is the abstract?</h3>

To investigate the potential lignin values, agricultural residues (apple tree pruning, olive tree pruning, and almond shell) and industrial residues (kraft black liquor) were employed as source materials for lignin extraction via various fractionation procedures (kraft, organosolv, acetosolv and acetosolv and formosolv processes). Py-GC/MS, FTIR, and GPC were used to characterise the separated lignins. The fractionation method had a significant impact on the average molecular weight (Mw) assessed by GPC. The severe circumstances of the acetosolv and acetosolv-formosolv procedures favoured repolymerization, resulting in high Mw lignins. Because of the longer retention durations, the EKL had a smaller Mw. Except for almond shell lignin, which has the highest relative abundance of G-type phenols, all lignins have higher relative abundances of S-type phenols.
