Summary of "Upgrading Pectin Production from Apple Pomace by Acetic Acid Extraction."

Pectin, as one of the most widely used functional polysaccharide, can be abundantly extracted from apple pomace which is the main by-product of apple juice industry. In the case of 110 min, 10% (w/w) acetic acid (AA), and 100 °C, extraction yield of pectin reached 19.6%. Compared with mineral acid-extracted pectin, the yield, molecular weight, galacturonic acid content, and DE of the AA-extracted pectin were higher while neutral sugars were lower. Furthermore, the AA-extracted pectin solution demonstrated a higher viscosity during the shear rate increased, and a higher G″ modulus than pectin extracted with mineral acid and commercial pectin possibly because of stronger polymer chain interaction, which was reflected in gel textural properties. The green approach for the pectin production, in terms of pectin components was developed from apple pomace using AA that was highly competitive and environmentally friendly process.

Medical and Biotech [MESH] Definitions

ACETIC ACID or acetic acid esters substituted with one or more CHLORINE atoms.

Acetic acid and its derivatives which may be formed by substitution reactions. Mono- and di-substituted, as well as halogenated compounds have been synthesized.

A very strong halogenated derivative of acetic acid. It is used in acid catalyzed reactions, especially those where an ester is cleaved in peptide synthesis.

Derivatives of phenylacetic acid. Included under this heading are a variety of acid forms, salts, esters, and amides that contain the benzeneacetic acid structure. Note that this class of compounds should not be confused with derivatives of phenyl acetate, which contain the PHENOL ester of ACETIC ACID.

A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
