Abstract

The invention relates to an ultrasonic-assisted lye tomato peeling method and a product, and belongs to the technical field of agricultural product processing. The method combines lye treatment and ultrasonic treatment for tomato peeling; process conditions of the lye treatment and ultrasonic treatment are properly set, so that final tomatoes can not only achieve 100% peeling rate and 90% of the peeling yield, but also have most of the tomato red layer and lycopene retained; and the peeled tomatoes are obviously superior to the tomatoes obtained by traditional lye peeling in color and nutrients. Compared with traditional lye treatment, the method reduces the amount of chemical reagents and shortens the treatment time of tomatoes in lye; compared with an existing power ultrasonic peeling method, the method reduces ultrasonic temperature, and overcomes the drawbacks that the existing ultrasonic treatment is insufficient to crack the tomato skin. The method is suitable for industrial production and has great promotion value.
