on the cooking time of dehusked splits. It is not the mechanicalaction of the roller machine or disk shellers that inuence the cooking time, but the pre-treatments given to seeds before dehulling that considerably inuenced the cooking time,as observed in dehulling pigeon peas (. Prolonged soaking of the seeds in water andsubsequent sun or mechanical drying increased the cooking time of many grain legumes(1,1,. Singh ( observed that soaking and oven-drying (6 , overnight) of pigeon pea seeds before dehulling considerably increased their cooking time (Table .

Furthermore, it was observed that although prolonged soaking of whole seeds in water increased the cooking times of respective dehusked splits, soaking in 1% solutionof sodium carbonate generally decreased it considerably. According to this study, differ-ences in the cooking time of dehusked splits were signicant, owing to genotype andpretreatments. This implied that genotypes coupled with pretreatments would also play an important role in inuencing the cooking time. Additional studies on the inuence of pretreatments used in commercial dehusked splits mills on their cooking quality need tobe performed. 4.7 Standards for Milling Quality Several research workers have attempted to dene milling quality of pulses. These have remained at only the laboratory level and, even today, the market value of the dehuskedsplits is largely decided by the traders. The price for the milled product is xed, dependingon number of grains with intact husk (partly or wholly) in the sample, chipping of
