Starch/Ethanol

To make full use of starch-base raw materials, the starch must be d to small molecules in order to produce sweeteners or provide fermentable sugars. Starch & ethanol enzyme can catalyze this kind of reactions and convert starch to glucose. What's more, it can also the protein in starch-based feedstock to release more nutrition, increasing the yield of fermentation products. As a kind of food addictive, starch & ethanol enzyme plays an important role on starch sweetener and ethanol industry improving production efficiency greatly.

Types of Starch and Ethanol

SuperAA™ X5 Alpha-Amylase

SuperAA™ X5 Alpha-Amylase can α‐1,4‐glucosidic bonds of starch to reduce slurry viscosity with 'liquefy' effect producing short chains of dextrin and small amount of oligosaccharides.

FastLIQ STAR150 Alpha-Amylase

FastLIQ STAR150 Alpha-Amylase can hydrolyse α- 1,4 glycosidic bond randomly. The viscosity of starch slurry decreases rapidly because of the high reaction rate and yielding short chain dextrins and a little oligosaccharides. FastLIQ STAR150 Alpha-amylase can be applied in liquefaction process based on starchy materials to produce starch sweetener.

LiqFINE BAA 1.0

LiqFINE BAA 1.0 is a kind of low-pH and thermostable amylase with high activity， can hydrolyse α- 1,4 glycosidic bond randomly. The viscosity of starch slurry decreases rapidly because of the high reaction rate and this process is called liquefaction yielding short chain dextrins and a little oligosaccharides. It can also enable high dextrose yields later in saccharification.

FAQs Of Starch/Ethanol

What are the advantages of enzymatic hydrolysis sweetener compared to the one with hydrolysis process?

A:

(1) The factory can get higher convertion rate utilizing enzyme instead of .

(2) The enzymatic reaction is under mild conditions with less operational risk.

(3) The taste is better than traditional hydrolysis sweetener.

Why do yeast need enzyme in ethanol fermentation?

A:

(1) Yeast can't utilize starch directly.

(2) Enzyme can break down long starch chain into small molecules which can be absorbed by yeast to produce ethanol thus improve utilization rate of starch.

What's the purpose of adding protease in starch-based feedstock fermentation?

A:

Corn starch is the common feedstock applied in ethanol production and it also contains a small amount of protein. Protease can hydrolyse protein to free amino nitrogen providing nutrition to yeast and finally increase ethanol yield.

What are the key benefits of amylase in starch sugar and fermentation industry (e.g., amino , citrin)?

A:

(1) Consuming less chemicals and no harm to environment.

(2) Boosting DX levels by 0.3% points.

(3) Increasing fermentation yields with more fermentable sugars.

(4) Widely worked on all types of starch-based size.

(5)Less calcium reliance and no extra addition of calcium with use of tap water.
