Comparison of equilibrium molsture content among seven corn hybrids

Ricardo Muñoz C.1 y Virginia Aguilar G.1

The desorption and adsorption equilibrium moisture content were determinated in seven corn hybrids (5 filnt and 2 dent). The static method of saturated salt solutions was used at 25 ºC and 75.3% of and relative humidity, respeetively. A randomized block design with sampling (7 x 3 x 2) was used. The Duncan Test was applied for mean comparison. Significant differences were obtained among oorn hybrids in each phase, adsorption and desorption. The minimum and maximum equilibrium moisture content data for seven corn hybridous to desorption were 17.45 and 18.26% dry basis and adsorption were 16.64 and 17.32% dry basis, respectively. A significant contrast test was obtained far equilibrium moisture data between the flint and dent corn hybrids.
