Researchers test the action of 1-MCP in apple cultivar Eva
Researchers from Universidade Federal de Minas Gerais, and Universidade Federal de Lavras, Minas Gerais, Brazil, demonstrated that the application of the compound 1-MCP after harvest of apples produced in Minas Gerais state was effective in increasing the shelf life of fruit for up to 135 days. The study was published in Ciência Rural journal, v.43, n.12, December of 2013.
The experiment evaluated the effect of specific doses of the compound in physiological and physico-chemical quality of Eva apples during refrigerated storage. After the treatments with different doses of 1-MCP (0.10, 50, 100 and 500 mg L-1), the researchers stored the fruit in cold storage at 0.5 º; C for up to 135 days. Cold storage and application of the product resulted in a lower production of ethylene in fruits treated with doses of 10, 50 and 100 mg L-1. The control group lost 45% of its firmness, while the treated groups lost on average 27% of their firmness. Fruits treated with lower doses of the product showed the best action of 1-MCP.
For the researcher Camila Fante, the data obtained in the study provide a solution to the producer of apples cultivar Eva who may suffer losses after harvest. "The producer can store the fruit for longer, until the market offers a better price, or even after the sale will be assured that the product will get more quality time on the shelf of the distribution market," she says.
The action of 1-MCP had already been confirmed in other apple cultivars, but as said Camila, there are no studies confirming this effect in apples cultivar Eva, fruit that is being produced in Minas Gerais and distributed to a large number of Brazilian states.
