Determination method for quantifying hardness and toughness of watermelon peel

The invention provides a measuring method for quantifying the hardness and toughness of watermelon peel, which comprises the following steps of: measuring the hardness of the watermelon peel, namely performing a puncture test on the watermelon peel by using a P/2 probe of a texture analyzer, applying a TPA mode, controlling the speed before measurement to be 10mm/s, the test speed to be 2mm/s, the speed after measurement to be 10mm/s, the test distance to be 10mm, the automatic trigger force to be 5g, and the maximum test force to be the hardness of the watermelon peel; and measuring the toughness of the watermelon peel: performing a cutting test on the watermelon peel by using an HDP/BSK probe of a texture analyzer, and testing the toughness of the watermelon peel by applying a TPA mode with the speed before measurement being 10mm/s, the testing speed being 2mm/s, the speed after measurement being 10mm/s, the testing distance being 10mm and the automatic triggering force being 5g. According to the method, th
