Determination of Thermostability Degree of Lycopene in Watermelon (<i>Citrullus lanatus</i>)
The aim of the work was to determine the degree of watermelon (<i>Citrullus lanatus</i>) thermostability according to the content of the present bioactive compounds and antioxidant properties. The watermelon samples were exposed to the following temperatures/time regimes: 40, 70, and 100...
