응용 분야
개요Methyl-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.
제조 방법
By condensation of citral with methyl ethyl ketone (see methyl γ-ionone or α-iso-methylionone)
