Determination of thermostability degree of lycopene in watermelon (Citrullus lanatus)

Popis výsledku v původním jazyce

The aim of the work was to determine the degree of watermelon (Citrullus lanatus) 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 &amp; DEG;C; 2, 5, and 15 min. The sample characteristics were monitored by spectrophotometric and chromatographic methods. Statistically significant (p &lt; 0.05) differences were observed between the heat-treated samples compared to the heat-untreated control sample; differences were found almost between all samples. The total polyphenol content increased in all heat-treated samples. The highest total polyphenol content was observed among samples treated at 40 &amp; DEG;C for 15 min (1.38 &amp; PLUSMN; 0.01 mg/g). Lycopene content (measured by spectrophotometer) also increased in the same samples exposed to 40 &amp; DEG;C for 5 min (65.45 &amp; PLUSMN; 0.20 mg/kg), though higher temperatures (70 and 100 &amp; DEG;C) resulted in lycopene degradation. Chromatographic method (measured by high-pressure liquid chromatography) showed lycopene degradation after each heating treatment. Not unambiguously, results and observations were not found in antioxidant activity due to oscillations in measured bioactive compounds. The obtained results emphasize processes in heat-treated watermelon, and they can be useful in the production of different products where this food commodity can be included.
