ASAE Standards for Moisture Determination

ASAE Standard S410.1 (DEC92) - Moisture Measurement - Peanuts

A standard has been developed for moisture determination of whole peanuts with hulls. At least 200g of peanuts are shelled. The hulls and kernels are placed in separate containers. The kernels are placed in the dish in a layer that is a maximum of three kernels deep. Containers are placed in a convection oven and dried at either 130±3°C for 6 hours or 100±3°C for 72 hours. The moistures of the hulls and the kernels are determined separately and the results are combined to give the whole peanut moisture. The procedures for handling the dishes and samples are similar to those used for grains and seeds. An alternative procedure can be used when only the whole pod moisture is needed. An oven temperature of 130°C is used and the required drying time is determined from a chart using the sample size and approximate initial moisture content.
