Northeast Research and Demonstration Farm
The ISU Northeast Research Farm has been evaluating food-grade soybean varieties for the last five years, and for the last three years has included the new Iowa State low linolenic soybean varieties. The “low lin” soybeans have lower levels of linolenic acid, which reduces or eliminates the need for partial hydrogenation, a process used to extend freshness of food products and the frying life of conventional cooking oils. The level of linolenic acid determines whether it will reduce or eliminate the need for hydrogenation. The partial hydrogenation process results in the formation of trans fatty acids, which are linked to heart disease because they elevate LDL (bad) cholesterol while lowering HDL (good) cholesterol. Producers need performance data to determine whether the premium offered for growing the new soybeans is adequate. Premiums are designed to cover yield drag, identity preservation cost, and the higher value of food-grade soybean products.
