Abstract
Soybean seeds var. CM. 60 has been processed and dried to 9.06 percent moisture content. Seeds were stored in 4 different kinds of plastic bag i.e. Metallized film, Aluminum foil, Polypropylene, and Woven Polypropylene for a period of 4 months under controlled temperature (16 o C) and relative humidity (65%). The experimental design was arranged in Factorial in RCB consisting of 2 factors; storage period and packaging material. Changes in fungal flora, water activity value, Carbon dioxide and Oxygen level, standard germination and vigor by accelerated aging technique, electrical conductivity test and acidity value were monthly determined, it was found that seed moisture content was increased in time and showed positive correlation with water activity value and negative correlation with seed germination and seed vigor showed in terms of low percentage standard germination, the electrical conductivity from seed exudates. Oxygen level showed positive correlation with free fatty acid value and showed positive correlation with storage fungi: Aspergillus sp., A. flavus, A. glaucus, A. niger, A. terreus and Penicillium sp. While field fungi: Cercospora kikuchii, Curvularia lunata, Fusarium spp. and Macrophomina phaseolina were decreased. From this experiment, soybean seeds were stored in Metallized film bags and Aluminum foil bags observed highly standard germination and seed vigor, and keep water activity and seed moisture content in low level could delay seed quality deterioration followed by Polypropylene bags and woven bag. Background and Aim of the Study Soybean seeds (Glycine max) have highly protein and lipid component (David, 1984) and could maintain their germinability only 3-4 months under room temperature. Moisture content and oxygen were the main causes for lipids autoxidation in soybean to lead to rapidly seed deterioration and the quality will be decline (Ching, 1973; Hartman et al., 1994). Temperature is another important factor for stored soybeans because chemical changes and growth of fungi such as increased with temperature in soybeans. However, another way for prolong storage life in soybean seed without chemical using is different kind of packaging materials and packaging material could be prevent the main cause seed deterioration such as moisture content and O2 concentration. Methods Soybean seeds var. CM.60 had processed and dried to 9.06 percent moisture content. The experiment design was arranged in Factorial in RCB consisting of 2 factors; storage period and packaging materials. Seed were stored in 4 different types of plastic bag i.e. Metallized Polyethylene Terephthalate (MPET), Aluminum foil (AF), Polypropylene (PP), and Woven
