With traditional commodity grain production, high and low quality grain lots are often blended to achieve a maximum allowable level of foreign material, splits, damaged grain, as measured by historical grain quality standards. In contrast, Identity Preserved (IP) grain crops are grown and handled under controlled conditions and delivered for specialty use.
IP grain in general refers to specialty production, segregation, and identification of food grade soybean varieties through specialty marketing channels so the end user of the product is assured that the specific variety is pure and meets minimum standards. Typically a contract grower agrees to produce, harvest, store and deliver the grain without mixing food grade soybeans with other varieties. The long process begins with the planting of pure Certified or Branded seed of a known variety. Independent third party record keeping, field inspections and post harvest lab testing services are available to monitor the quality throughout the IP process.
IP food grade soybeans are carefully harvested to avoid mechanical damage, other crops, and dirt stains. Clean equipment is used, with the grain stored in clean bins, aerated periodically to control moisture and transported to markets in clean cargo containers, bags, or via clean trucks.
