Lignin and pectin
Nettet21. jul. 2024 · The results showed that pectinase/alkali-oxygen method after the first alkali treatment had a good effect on the degumming of sisal fiber, and most of the non-cellulose components such as hemicellulose, lignin and pectin had been removed. After pectinase treatment, the cellulose content and crystallinity were 71.87% and 66.29%, respectively. Nettet14. apr. 2024 · Alkali treatment can reduce the hemicellulose, lignin, pectin, wax and oil contained in the raw fiber. The mechanism is that OH − weakens the hydrogen bond …
