Trial Block Operations
José María Fernandez
SNFL’s role in the Mediterranean countries first started in a small test block in Murcia, Spain where a large number of table grape varieties from California had been imported with the ambition to revolutionize the old, traditional table grape industry. Hundreds of visiting growers passed through this small test block, and gradually, following extensive technical development and promotion, the Sheehan varieties began to be planted on a large scale across the Mediterranean region.
The project presented in this document aims to develop new varieties of seedless table grapes with healthy properties for the consumer. For this, new genetic material will be obtained from varieties with a high concentration of antioxidants, with a special focus on enrichment in phenolic compounds, and their effect on glucose absorption will be studied in vitro after simulating its gastrointestinal digestion. Likewise, its effect on insulin resistance will be evaluated in vitro. A comparison will be made with normal table grape varieties, and also a reference fruit whose consumption is associated with a low caloric content will also be analysed. In addition, it will be taken into account that the varieties developed have new flavours with good acceptance in the market.
