Food Sweeteners
Types
Nutritive
Occur naturally
Provide calories
4 cal/g
Act as preservative
Eg. Jam and jellies
Fermentation bread and pickle
Examples
Sucrose
Disaccharide= glucose + fructose
Functions
Increase viscosity
Good solubility
Browning (Maillard reaction)
Enhance flavour
Improve shelf life
Aids in fermentation of baked goods
Lactose
Disaccharide derived from milk
1/6 as sweet as sucrose
Functions
Control crystallization
Act as flow agent
Browning in baked product
Increase flavour and tender stucture
Dextrose
A reducing monosaccharide
About 67% of the sweetness of sucrose
Provide mouth cooling effect
Application
Procced meat
Baked goods
Glucose syrup
Derived from starch
Acid or enzyme hydrolysis
High Dextrose Equivalence (DE)
Less viscosity
More sweeter than Low DE
Low DE
Impact viscosity, moisture content and sweetness
Honey
1-1.5 times sweeter than sucrose
Non- nutritive
High intensity sweeteners
Most widely used
No calories
Artificial
Examples
Aspartame
Do not promote tooth decay
Used in low calories food products
Neotame
Sweetest non- nutritive sweeteners
Made of 2 amino acis
Aspartic acid
Phenylalanine
Sucralose
Do not react chemically with other ingredients
Saccharin
May provide unpleasant aftertaste
Acesulfame potassium
High level causes bitter taste
Has excellent solubility
Functions
Improve texture
Balance acidity of food
Mask odd and unwanted flavour
Lower freezing point
Eg. ice cream
Act as preservatives
Decrease moisture content
Decrease water activity
Inhibit microbial growth and spoilage
Extend shelf life of products
Improve natural sweetness
Aids in fermantation
Soften the bread
Lactic acid produce by glucose fermentation
Increase dough yield
Bulking agent
Increase size of product
Applications
Bread
Candies
Ice cream
Jam
Syrup
Corn sugar
Fruit juice
