1. Introduction
1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
temperature conditions and 2kg MSW samples were utilized. Moisture content selected was 15% and 30%. The bottom temperature varied from 600℃ to 1000℃.
Gasification products such as ash, liquid, gas prepared for each gasification temperature were analyzed in terms of composition and heat value.
The yield of gas products(CO, H2, CH4) were higher at elevated temperature. Main components o
