Starch-Derived Liquid Adjunct Manufacturing

Question 1

What are commercial liquid sugar syrups produced from?

Answer 1

Hydrolysis of cereal starch

These syrups undergo greater processing than solid adjuncts, making them more costly.

Question 2

What is the process for breaking down starch during syrup manufacture similar to?

Answer 2

Processing grits in the brewhouse

Only acids and commercially-produced enzymes are used.

Question 3

What is the first process used for manufacturing liquid adjuncts?

Answer 3

Acid hydrolysis

Strong acids are used to hydrolyse the starch.

Question 4

What combination of methods is used in acid/enzyme starch hydrolysis?

Answer 4

Acid and enzymes

This method liquefies the starch before adding more enzymes to convert it into sugars.

Question 5

What is the method that uses only enzymes for starch processing?

Answer 5

Enzyme starch hydrolysis

Enzymes are used for both liquefaction and saccharification.

Question 6

What do the enzymes in liquid adjuncts help control?

Answer 6

Carbohydrate profile

Manufacturers can control the proportion of each form of sugar and non-fermentable material.

Question 7

Fill in the blank: The degree of processing for liquid sugar syrups is _______ than that of solid adjuncts.

Answer 7

greater

Question 8

True or False: Liquid adjuncts can only be produced using enzymes.

Answer 8

False

Liquid adjuncts can also be produced using acid hydrolysis.

Question 9

What are the two main functions of enzymes in enzyme starch hydrolysis?

Answer 9

Liquefaction and saccharification

Both processes are crucial for converting starch slurry into sugars.
