外文摘要:
NOVELTY - Reducing organophosphorus pesticide residue in juice comprises (1) adding the juice to be processed to a processing chamber; (2) opening a constant temperature circulator and setting its temperature to 5-15 degrees C, pre-cooling the juice to be processed for 5-10 minutes; (3) setting the ultrasonic processing power to 100-500 Watts and setting the temperature of the constant temperature circulator to 15-40 degrees C, cooling the juice with circulating water; starting the ultrasonic device for ultrasonic processing; and (4) carrying out ultrasonic processing for 15-120 minutes.
USE - The method is useful for reducing organophosphorus pesticide residue in juice (claimed). The method is useful for the field of food safety. The method is also useful for removing the organophosphorus pesticide residue in other liquid foods.
ADVANTAGE - The method processes the juice with ultrasonic technology and the concentration of the organophosphorus pesticide in the processed juice is reduced obviously. Moreover, the use of the circulating water cooling device during the process avoids the negative effect on the juice caused by the increased temperature after the ultrasonic treatment. The method is simple and practical.
