TAILIEUCHUNG - Pectin and cellulose extraction from passion fruit peel waste

Pectin and cellulose were successfully extracted from passion fruit peel waste. The maximum pectin yield of the process was at pH=2 for h. The pure cellulose obtained from the passion fruit peel waste was prepared by refluxing of the passion fruit peel powder with 1 M NaOH and M HNO3 solutions at 90°C for 1 h and h, respectively. The passion fruit peel cellulose was converted to carboxymethyl cellulose (CMC) by etherification. The pure cellulose was soaked in a mixed solution of isopropyl alcohol and NaOH for h. After that, it was reacted with cholroacetic acid at 70°C for h. The optimum conditions for carboxymethylation were 5 g cellulose, g cholroacetic acid, and 15 ml 20%w/v NaOH. The optimised product had a degree of substitution (DS) of and was used as constituent in a biopolymer. | Pectin and cellulose extraction from passion fruit peel waste
