摘要: This invention relates to an efficient process for separating and recovering aroma flavor volatiles from fruit or vegetable juices lowering the pectin levels in cloudy juices. The involves removing aroma/flavor juice by forming a microaerosol spraying at temperature of 45° C. 110° through nozzle having diameter about 100 microns 600 velocity m/sec. 250 into vacuum chamber 5 mm 200 Hg temperatures 10° 55° then treating recovered fraction with pectinase which is essentially free esterases. decreased level increases gustatory display improves mouthfeel beverage. Decrease achieved without formation methanol hydrolysis important ester compounds. Clear containing virtually pristine composition are produced after ultrafiltration special enzyme treated
