Valorization of transgenic Tomaffron-based products enriched in saffron apocarotenoids

Saffron spice (Crocus sativus L.) is highly valued for its bioactive apocarotenoids, including crocins, picrocrocin, and safranal, but its commercial production is limited due to labor-intensive cultivation. In this study, Tomaffron, a transgenic tomato-based platform enriched with saffron apocarote...

In this study, Tomaffron, a transgenic tomato-based platform enriched with saffron apocarotenoids, has been processed into different tomato products to assess their suitability as carriers of these valuable apocarotenoids.
