5. Conclusion

Controlling the supply of food products requires methods for listing and monitoring suppliers, evaluating them and checking the conformity of purchased products. The globalization of trade and the emergence of numerous intermediaries make the formalization of these practices an essential part of today's quality systems. Computerized data exchange, certification systems, new market requirements and rapid analysis methods have all revolutionized food industry practices over the last few decades. It's a safe bet that this trend will continue: the market will demand ever greater quality and consistency (nutritional, sanitary...), and companies and their suppliers will increasingly seek to control supplies and be as responsive as possible.
