water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production
2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
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

water
- charged molecules interacts with water as solvent
- polar compounds can also interact with water
- hydrophilic interaction (water-loving)
ion-dipole and dipole-dipole interactions
- hydrophobic interaction (water-hating)
non-polar molecules do not dissolve in water
- amphpathic : a single molecule has two portion, polar and non-polar
fatty acids form micelles
