Enzyme in Food Processing
Have long been used in food processing.
They are an essential part of our current methods for making cheese,
yogurt, beer and wine.
Enzymes can be used to :
Alter the appearance, aroma, texture and flavor of a product.
Deliver nutrients more effectively to the body or to make a food that is
difficult to digest a bit easier to swallow.
Accelerate the good fermentation time, giving a finished product in weeks
instead of months.
Advantages of Enzyme
They are welcomed as alternatives to traditional chemical -based
technology, and can replace synthetic chemicals in many processes.
Processes which use enzymes therefore have fewer side reactions
and waste by-products, giving higher quality products and reducing the
likelihood of pollution.
They allow some processes to be carried out which would otherwise
be impossible.
APPLICATION OF ENZYME IN FOOD PROCESSING
Step 1 Decide what you would like your enzyme to do.
Enzymes function in unique and predetermined ways.
Step 2 Determine the probable target market for the product.
Step 3 Research the physical components of the product (production materials
and methods) to find the most efficient enzyme match.
Step 4 Decide which enzyme would work best for your product.
.
Step 5 Make sure that you understand very clearly and deeply about the activities
of the enzyme
Step 6 Establish a method so that the enzyme can act efficiently without
undesirable degradation of food components (such as freezing or
refrigeration) and ascertain the shelf life of the finished product.
Step 7 Find a source for your enzyme and produce a test batch of your product to
determine if the enzyme functions as you hoped it would.
HOW TO USE ENZYMES IN FOOD PROCESSING
Objective:
Remove the remainder of the
fruit pulp.
Remove the mucilage which
surrounds the coffee bean.
Remove the coat of coffee bean.
LOGO
Mechanism:
breaking down cellulose, pectin and protopectin (the main
components in coffee pulp and the mucilage)
The enzyme used:
cellulase (endocellulase and extracellulase, β-glucosidase)
pectinase
protopectinase
The source of enzymes:
Produced by the fungi named Aspergillus Niger
***Notation: The fermentation process has to be carefully monitored to ensure that
the coffee doesn't acquire undesirable, sour flavours.
Purify the coffee bean from the undesirable
substances
Save the time.
Improve the coffee flavor.
Improve the quality and safety of the product
