Newly harvested and cured cv. Florunner jumbo (>8.33 mm dia), split (>6.75 mm dia) and no. 1 (<7.14, >6.35 mm dia) peanuts were packaged as shelled seed in plastic bags, CO2 atmosphere; in burlap bags, and as farmers stock, bulk. After 1, 3 and 6 mo ambient storage, they were tested for moisture, color of raw seed-coat and color and flavor of peanut butter. Packaging showed no effect on flavor, but seed size did. No. 1's showed a linear loss of flavor with time and generally had the highest moisture level and produced the darkest butter. After 6 mo, burlap-bag storage yielded the darkest raw seed coats, while plastic bag-CO2 generally maintained the highest moisture level and produced the darkest butter.
