2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.

1. 육류의 고기 구성요소
육류는 수분과 단백질 그리고 지방·탄수화물ㆍ비타민ㆍ미네랄로 구성된다.
① 수분은 고기의 약 70%를 차지하고 있다. 수분은 많은 성분들을 용해시켜 포함하고
있으므로 그 함량 및 화학적 존재 상태는 육질에 큰 영향을 미친다.
② 단백질은 약 18.5%(16∼22%)를
Hwajeon
Hwajeon is a Korean traditional
desert.
Knead the glutinous rice flour with boiled water.
Pan-fry the dough over low heat.
Decorate the top of the dough with petals.
It can give the fragrance of a fresh flower.
And with syrup it is very sweet.

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
