“…This might be because the seed became softer, more difficult to separate from the hull and kernel, and more readily broken as the moisture level increased. These findings are consistent with dehulling of flaxseed, which has a lower moisture content that is favorable for dehulling [8], but paddy and sorghum have higher moisture contents that are favorable for dehulling at 10-14 percent [9] and 14.3 percent [10], respectively, to obtain the best-dehulled seed.…”

“…The initial moisture content of Nymphaea pubescens seed was determined by the hot air oven method at 105°C for the period until the constant weight [6]. The Nymphaea pubescens seed was conditioned for different moisture content levels (10,13,16, and 20% wb). The seeds were added distilled water and mixed to get more than the initial moisture content.…”

Grain Nymphaea pubescens has been widely consumed as traditional food such as snack bars and cake in South Kalimantan. The first experiment of this study focused on the difference in moisture content of N. pubescens seed after harvest to prevent seed decay and higher dehulling recovery. Dehulling was performed with a laboratory model seed polisher/dehulling apparatus. Dehulling experiments were carried out on samples exhibiting moisture contents ranging from 10% to 20.6 %. Dehulling of N. pubescens seed was affected by moisture content. The optimum grain moisture for dehulling N. pubescens seed was 10% and 13.2%, respectively, with a higher amount of dehulled seed, resulting in dehulling efficiency of 48.6% and 45.6 %, respectively, and lower levels of powder and broken seed. The dehulling efficiency decreased with an increased moisture content of N. pubescens seed.
