Study on the Changes of Moisture Content, Temperature and Forecast of Growth and Spoilage Process of Fungi in Stored Wheat

摘要

The changes of moisture content,temperature,initial growth time and spoilage process of fungi were studied.The different moisture contents of wheat samples were stored in incubators at 10,15,20,25,30,35 °C respectively.The samples were taken periodically to determine the fungi spores,and the period of experiment was 120 d.The results show that the growth of fungi increased with the temperature increasing,and fungi growth was most rapid at 30°C,and decreased at 35 °C gradually.In six experimental temperatures,the optimum temperature was 20 °C based on stored grain safety and economic evaluation.According to the results of the study,we first propose the relation curves of the moisture content,temperature,fungal initial growth,and spoilage of process in stored wheat.
