How to make high
fructose corn syrup (HFCS)
3 kinds of enzyme
reaction
1)
Starch is
made of a lot of glucose. Add Alfa amylase (liquefying amylase, type of
digestive enzyme can be obtained from microorganism ) and water into starch and
at 95 C. degree, Starch will be decomposed.
(Starch molecule is too big, so at step 1 we want to make it into smaller
particle by liquefaction, the process to convert something to liquid)
2)
After
liquefaction , cool until 55 degree C,
add glucoamylaze which will separate each individual glucose apart from
starch, now we have much smaller particle, glucose.
3)
At 60
degree C, add gluco-isomerase (type of enzyme, made from bacteria) which will
convert glucose to fructose, fructose is better in quality of sweetness, which
is more commercially preferred
Note that starch itself is not sweet because starch is long chain of bunch
of glucose. Our tongue can feel sweetness if it is individual
glucose, but in the form of glucose chain, we can’t.
Then after some sort of processing, corn syrup will made
Corn syrup is as sweet as or slightly sweeter than can sugar, depending on
how they process after the third step
The lower the temperature, the sweeter corn syrup is. Soda is sweeter when
it’s stored in refrigerator
It’s cheaper than cane sugar, about 70% price of cane sugar, so nowadays in
order to reduce production cost almost every soda product use corn syrup (Coke,
Pepsi)
How to make
biomassethanol
Theoretically we can
make bioethanol from anything with high carbohydrate
(sugar cane, corn,
rice, etc)
The way to create
bioethanol is basically same as they way to make alcohol
Dry grind method –
newly developed factory in US
Starch ingredientàdry grindàsaccharificationàbiotic
fermentation(organic decomposition by microorganism to produce certain kind of
material) 10% ethanol àdistill, 95% ethanol àdyhedrate, 99.5% ethanol àethanol
Bio ethanol is a fuel
Same type of alcohol Found
in alcohol beverage
Motor fuel
Additive for gasoline
Occupy 10% of car
gasoline (cars nowadays can run on blends up to 10 %)
