CONTINUOUSLY EXTRACTION AND PURIFICATION OF PHENOLIC COMPOUNDS AND PECTIN FROM ASIAN PEAR PEEL

摘要

The present invention relates to a method for continuously extracting and purifying phenolic substance and pectin from pear peel, and mixing crushed pear peel with 70% methanol or 70% acetone in a ratio of 1: 4, crushing and extracting twice in succession with filtrate and The residue was obtained by concentrating the filtrate, and then concentrated or lyophilized and passed through an adsorbent to purify the mixture to obtain a phenolic substance mixture. The mixture was adjusted to 2.0 and extracted at 90 ° C. for 1 hour to obtain a filtrate, and isopropanol was added to the filtrate to obtain a precipitate. The precipitate was washed with ethanol to remove sugars, dissolved in water, filtered and precipitated, or dissolved in water and filtered. After lyophilization is characterized in that the purified pectin to obtain.;Pear peel, Pear phenolic substance, Pear pectin, Continuous extraction, Purification
