    • This invention relates to an efficient process for separating and recovering aroma and flavor volatiles from fruit or vegetable juices and for lowering the amount of sugar in juices. The process involves removing the aroma/flavor volatiles from juice by forming a microaerosol by spraying juice at a temperture of from 45.degree. C. to 110.degree. C. through a nozzle having a diameter of about 100 microns to 1200 microns at a velocity of 100 m/sec. to 250 m/sec. and into a vacuum chamber at 5 mm to 200 mm Hg and at temperatures of from 10.degree. C. to about 55.degree. C. and then treating the recovered juice fraction with a yeast. The alcohol formed during this fermentation reaction is removed by distillation, preferably by the same aerosolization process as the volatiles are removed. The aroma and flavor volatiles are returned to the juice to provide a good tasting low calorie fruit juice.
    • 本发明涉及一种从水果或蔬菜汁中分离和回收芳香和风味挥发物并降低果汁中糖分的有效方法。 该方法包括通过在45℃至110℃的温度下喷雾直径约100微米至1200微米的喷嘴以100的速度形成微溶胶,从而从果汁中除去芳香/香味挥发物。 m / sec。 至250米/秒。 并进入5mm至200mm Hg的真空室中,并在10℃至约55℃的温度下进行处理,然后用酵母处理回收的果汁部分。 通过蒸馏除去在该发酵反应期间形成的醇,优选通过除去挥发物的相同的气雾化方法。 将香气和香味挥发物回到果汁中,以提供一种很好的品尝低热量果汁。
