White Labs Ultra Ferm - 10ml

For use in both Beer Brewing & Spirits Distilling. 

Brewers may want to produce light beers or dietetic beers which requires a controlled or complete hydrolysis of starch & dextrins to fermentable glucose.

Traditional brewing methods permit only 75 to 80% hydrolysis of starch present in the grain raw material. Ultra-Ferm amyloglucosidase permits total hydrolysis of dextrins to fermentable glucose, from all types of starch.

.......................................................

After starch liquefaction by alpha-amylase, dextrins are hydrolysed in glucose by amyloglucosidase, before alcoholic fermentation. Ethanol production is faster & yield is higher. The recommended saccharification temperature is 60°C.

A suitable substrate for saccharification is a liquefied starch with a dextrose equivalent (DE) between 10 and 20. A higher DE than 20 might reduce the saccharification efficiency. The concentration of the substrate will also influence the saccharification efficiency. A concentration of 20-25% is a general practice. ULTRA-FERM dosage, for given reaction time, depends on the amount of glucose requested. It is usually recommended to add 400 ml per ton of starch for a fast hydrolysis. Possible pH range of use is from 3.5 to 5.5 with optimal between 4.0 and 5.3.
