NSure launches new FreshNSure Pear test

NSure extends her range of tests by introducing the FreshNSure Pear test. This test provides a practical and reliable tool to determine whether a batch of pears has been treated with 1-MCP. 1-MCP leaves no residue after treatment. The FreshNSure test clearly demonstrates whether or not 1-MCP has been applied based on the activity of a specific set of genes. The test is currently available for the important pear variety ‘Abate Fetel’. Our FreshNSure pear test will be available for ‘Conference’ pears soon.

Pears are treated with 1-MCP to protect them from the adverse effect of ethylene, thereby improving shelf life and storability. Because 1-MCP delays ripening, it is applied in storage to maintain quality of recently harvested pears. However, in some cases 1-MCP treatment of pears results in pears that won’t ripen at all. Futhermore, because the use of 1-MCP leaves no residue, it is not possible to show the difference between treated or non-treated pears. Therefore, NSure has developed the FreshNSure test, measuring the activity of a selected set of genes that is affected due to 1-MCP treatment. This enables NSure to determine whether 1-MCP has been applied or not. Effect of treatment is measurable after 2 up to 20 weeks after the start of storage.

Pear samples (15 pears) must be taken directly from stored batches. FreshNSure’s practical sampling kit includes all tools needed to prepare a pear sample. One only needs to apply a few drops of juice to the sampling card. The test result is categorised in ‘not treated’ or ‘treated’. Test results are provided within 48 hours after arrival of the sample(s) at the laboratory. (sampling video)

NSure collaborates with several distributors and laboratories in Europe to allow local service and guarantee the shortest turnaround times.

NSure continuously works on further development of the FreshNSure test. Recently, our FreshNSure Apple test has been made available for a wider range of varieties and a FreshNSure test for kiwifruit is expected to be released in the near future.
