Lycopene‐rich food biomolecules from tomato processing waste: Green recovery, biopolymer‐based stabilisation, functional food applications and health relevance

Food Biomacromolecules, EarlyView.
Abstract Tomato processing waste, particularly peel and pomace, is a sustainable and low‐cost source of lycopene‐rich food biomolecules. Lycopene, a lipophilic carotenoid with an extended conjugated structure, provides intense red colour, antioxidant potential and functional value to tomato‐derived ingredients.

Use of predictive tools for the analysis of bioactive compounds in crocus SATIVUS L. flowers

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Crocus sativus L. (saffron) flowers have high bioactive potential because of their content of crocins, safranal and phenolic compounds. The development of predictive models based on near‐infrared (NIR) spectroscopy and partial least squares regression to estimate the antioxidant capacity of saffron flower, evaluated using oxygen ...
