Diposting oleh On Tuesday, December 17, 2013


Alkohol adalah persenyawaan kimia yg mempunyai rantai –OH, disekitar kita banyak ditemui jenis – jenis alkohol seperti spiritus, etanol disinfektan dan minuman keras. Alkohol bisa dibuat dengan proses fermentasi karbohidrat / gula. 
"Alcohol is a chemical compound  has -OH chain, we meet kinds of alcohol such as spirtus, ethanol disinfectant and hard drink. Alcohol can be made from fermentation of carbohydrates."
Macam – macam karbohidrat / gula adalah :
1. Monosakarida
  • Fruktosa (gula dari buah – buahan)
  • Galaktosa (gula dari pencernaan laktosa)
  • Glukosa (gula dari umbi - umbian)
2. Disakarida
  • Sukrosa (gula dari tebu dan jika dihidrolisis menghasilkan glukosa - fruktosa)
  • Laktosa (gula dari susu dan jika dihidrolisis menghasilkan glukosa - galaktosa)
  • Maltosa (gula dari biji – bijian / pati dan jika dihidrolisis menghasilkan 2 molekul glukosa)
3. Polisakarida
  • Pati / amilum
  • Glikogen
Karbohidrat berdasarkan "gugus fungsi yg diikat" dibagi menjadi 2 yaitu :
  • Aldosa (mengikat gugus aldehid) contohnya glukosa, galaktosa, ribosa
  • Ketosa (mengikat gugus keton) contohnya fruktosa
Proses pembuatan alcohol dinamakan proses anaerobic karena tdk membutuhkan oksigen bebas dan membutuhkan jamur ragi (Saccaromyces cereviceae). Bahan – bahan yg bisa dipakai utk fermentasi misalnya umbi singkong, ketan (tapai) dan anggur, manga, durian (bir).
"Manufacturing process of alcohol is anaerobic because of npt require free oxygen and using Saccaromyces cereviceae. Sunstances can be used for fermentation are cassava, sticky rice, grape, mango and durian."
Reaksi fermentasi : 


Etanol adalah salah satu golongan alkohol dan sering digunakan utk berbagai keperluan. Sedangkan CO2 adalah gas panas yg kita rasakan saat membuka wadah fermentasi.
Jika kita melihat proses pembuatan secara sederhana bahwa proses fermentasi dilakukan dalam proses tertutup (aerobik) karena jika terkena udara bebas maka reaksi fermentasi akan teroksidasi menjadi asam karboksilat shg hasil yg didapat rasanya masam.
"Ethanol is one of alcohol and often used for necessity and CO2 is hot gas which sensation while open of fermentation container.
If we know simplely process that fermentation is done close process due to if there is free oxygen so fermentation react will continue oxydizes to carboxylic acid and produce sour taste."
Produk2 yg diperoleh dg cara fermentasi adalah :
  • Bir
  • Wine
  • Yogurt
  • Keju
  • Tapai
