FEMA 2597 Chemical Properties,Usage,Production
Description
Methyl-α-ionone has an odor similar to α-ionone but lighter and
more rounded with a pleasant, fruity, and sweet nuance. May be
prepared by condensation of citral with methyl ethyl ketone (see
methyl y-ionone or α-iso-methylionone).
Pectic enzymes are indispensable for making high-density fruit juice concentrates or purees. Enzyme depectinization is required for apple juice concentrate of about 72° Brix, which is made on a large scale, as otherwise a gel would result rather than the desired liquid concentrate. Pectic enzymes are useful in treating orange, grape and prune pulps prior to vacuum puff drying.
