Description

WLN4100 Ultra Ferm - 10mL

ULTRA-FERM is a liquid amyloglucosidase (highly concentrated) from selected classical strain of Aspergillus niger. Ultra-Ferm can be used to make Brut IPAs.

Applications

1) To reduce saccharification times.
2) To saccharify unmalted cereal brews.
3) To increase attenuation.

Function In Beer Production

Brewers often want to produce light beers or dietetic beers. In these cases the brewer wants a controlled or complete hydrolysis of starch and 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.

In the brewhouse, the recommended application dosage of Ultra-Ferm is 0.8 to 3.2L per ton of starch. It can be added at the beginning of the mash-in. Ultra-Ferm optimal pH is between 3.5 and 5.5. Temperature should not exceed 60°C. Amyloglucosidase activity is completely destroyed when the wort is held at 85°C for 10 minutes.

Function In Spirit Production

After starch liquefaction by alpha-amylase, dextrins are hydrolysed in glucose by amyloglucosidase, before alcoholic fermentation. Ethanol production is faster and 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.

Optimal temperature is 60°C. Amyloglucosidase activity is completely destroyed when the saccharified liquor is held at 85°C for 10 minutes. As an example: a yield of 94% glucose can be obtained after 40 hours with 36000 AGI per kg dry matter; after 72 hours with 17000 AGI/kg and after 85 hours with 13000 AGI/kg, at pH 4.5 with temperature 60°C.
