Increasing the Lycopene Content and Bioactive Potential of Tomato Fruits by Application of Encapsulated Biological and Chemical Agents

Plant secondary metabolites play an important part in the human diet. This research investigated the effect of alginate microspheres loaded with chemical (calcium or copper ions) or chemical and biological (Trichoderma viride) agents on plant secondary metabolites synthesis of two tomato varieties ('Vasanta' and 'Abellus') in two types of greenhouse cultivation, hydroponic and soil. Targeted and controlled release of active agents facilitates the root of plants to respond to the encapsulated agents and stimulate the synthesis of investigated plant metabolites both in hydroponic and soil types of cultivation. A significant increase in lycopene (up to 230%), total polyphenols content (up to 61%), and the overall antioxidant activity (up to 77%) of the tomato fruits was found for all of the treatments, respectively. Encapsulated chemical and biological agents remarkably stimulate the synthesis of plant secondary metabolites in tomato fruits indicating its great potential in the production of value- added foods.
