Glucoamylase

Glucoamylase SUKAGluAm

INTRODUCTION

Starch, a high polymeric carbohydrate is a mixture of two polysaccharide, amylose and amylopectin. Starchy substrates like corn starch need to be acted upon by high temperature stable al-amylases to produce shorter length dextrins while glucoamylases are used mainly in the production of glucose syrup, high fructose syrups and starch hydrolysis for alcohol production.

DESCRIPTION

SUKAGluAm is a glucoamylase (amyloglucosidase) enzyme obtained from the controlled fermentation of the fungal organism, Aspergillus niger. The enzyme is widely used in brewery, manufacture of starch, starch sugar, alcohol, gourmet powder, antibiotics, etc.

WORKING MECHANISM

The dextrins produced by al-amylases are acted upon by exo-splitting glucoamylases (amyloglucosidases) which readily attack the terminal a-1,4 and a-1,6 glucosidic linkages from the non-reducing end of the released dextrins to produce 6-carbon b-D-glucose units. The enzyme also possess the ability to hydrolyze a-1,6-glucosidic linkages in isomaltose and dextrins.

PROPERTIES

• provides maximal benefit at 4.0 – 4.5 and at the temperature of 58 – 60°C (136 – 140).

SPECIFICATION

Enzyme activity ≥ 100,000 U/Ml

Bulk density ≤ 1.25g/ml

Unit definition: The amount of enzyme needed to hydrolyze 1 mg of starch in one hour at 4.6 at the reaction temperature of 40°C.

Standard: carry out the national code of People’s Republic of China QB1805.2-93

APPLICATION GUIDE

• is used in the manufacture of gourmet powder, antibiotics, citric acid among others. The enzyme is added at the rate of 100-300 U/g at 6.0-6.5 and temperature of 60°C.
• 120-150 U/g raw materials. (If raw material is not with high quality or rotten, the dosage of enzyme can be increased to 150-180 U/g raw materials.)

Note: the dosage of Glucoamylase in wine production should be determined by the length of fermentation cycle.

• SUKAGluAm is added at the rate of 100-300 U/g at 4.2-4.5. The temperature of the mixture is maintained at 60°C.

PACKAGING

SUKAGluAm liquid preparation is packaged in 25 kg/plastic drum or packaged in box or plastic woven bag for the solid form.

Alternative packaging is available upon request for smaller or larger volumes.

STORAGE

Store in a cool, dry place and away from direct sunlight. SUKAGluAm maintains its activity for considerably longer time when stored at lower temperatures (below 25°C). The product should not be frozen.

HANDLING PRECAUTIONS

SUKAGluAm is non-degradable. However, unnecessary with the product should be avoided. Long term exposure to protein based products such as SUKAGluAm may sensitize certain individuals to the product. Wash hands with warm soapy water after handling. Keep out of reach of children.
