Abstract:

Production of organic foods that are really grown and processed and their traceability during distribution from production to consumption are still of prime concern. Organic agriculture that reduces negative environmental impacts and produces healthy foods has become one of the preferred alternative farming practices, since it enhances soil fertility and carbon sequestration. Despite debates about sustainability and profitability of organic agriculture, the organic food industry is one of the fastest growing businesses, because market and social forces have created price premiums on organic foods. To label ORGANIC, producers should attest the use of synthetic fertilizers and pesticides. However, no standard method to detect the use of chemical fertilizers is available. Therefore, food manufacturers and markets put more efforts to strengthen reliability of organic food certification by adopting extra inspection systems that are not regulated by relevant laws. One adoptable inspection system is the use of natural 15N abundance (?15N) of crops and soils. Composted manure has a higher ?15N than synthetic fertilizer due to isotopic N discrimination. Differences in ?15N between isotopically different N inputs suggest that N isotope signatures of crop tissues could differ between organic and non-organic foods. In this regard, the use of ?15N can serve as a reliable biogenic marker not only to identify the use of synthetic fertilizers in organic certification but to ensure traceability and detect food adulteration, and this technique has been internationally patented and successfully launched into the Korean organic market. Here this essay reports experiences and feasibility in the future market.
