treatment to prevent recontamination with microbes; others, such as drying, allow food to be stored without any special containment for long periods.
Common methods of applying these processes include drying, spray drying, freeze drying, freezing, vacuum-packing, canning, preserving in syrup, sugar crystallization, food irradiation, and adding preservatives or inert gases such as carbon dioxide
vacuum cooling) : 원예산물을 밀폐된 챔버에 넣고 압력을 낮추면 물의 증발온도가 낮아지고 원예산물의 표면에서 물이 빠른 속도로 증발된다. 물이 증발할 때 주위로부터 증발열을 빼앗아 가는데 이를 이용하는 냉각 방식이다.
이 방법은 표면적이 큰 엽채류의 예냉 방법으로 적당하다.

First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca
Vacuum and freeze drying processes are used for products with delicate flavours and textures like coffee granules, eggs, prawns and vegetables. The process involves freezing, and evaporating the ice away, under reduced pressure. It is an expensive process but gives a produce which is high in flavour and palatability. Milk may be dried on rollers or by spraying concentrated milk into hot air chamb
treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and 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 decreasin
