Natural Cherry Flavor Recovery From Dilute

The demand for natural flavors is increasing both in America and Europe. This project will optimizean innovative technique to recover benzaldehyde (natural cherry flavor) from cherry pit hydrolyzate.The concept is based on the hydrolysis of crushed cherry pits, adsorption of benzaldehyde fromhydrolyzate passed through an adsorption bed, and recovery of the benzaldehyde by regenerating theadsorbent with CO2. Preliminary process screening with a synthetic benzaldehyde/water mixture hasindicated the scientific and economic viability of the adsorption process. Hydrolyzate adsorption is lessfavorable than the synthetic mixtures on the same adsorbent, however, another adsorbent has beenlocated with excellent hydrolyzate adsorption characteristics. The main objective of the proposedproject is to optimize the adsorption process using cherry pit hydrolyzate and to ensure the commercialviability of natural benzaldehyde from cherry pits.
