How are jellied products preserved?
• • • •
High sugar content Loss of water during cooking Acidity of products Cooking Grow It Eat It Preserve It!
Prevent molds and yeast
• • • •
Grow in an acid environment--like jellies Molds can produce mycotoxins that may be harmful Some people are sensitive to mold due to allergies and respiratory problems Easily destroyed at 140 o to 190 o F Grow It Eat It Preserve It!
Using paraffin to seal
•
Not recommended
•
Mold can grow under the paraffin and grow down into product Grow It Eat It Preserve It!

Grow It Eat It Preserve It!
Fruit
• • •
Contributes color and flavor Contributes some or all of pectin and acid Use fresh, canned or frozen fruit or fruit juice (no added sugar) Grow It Eat It Preserve It!
Pectin
• •
Causes fruit to gel Sources of pectin
o
Naturally in fruit
o
Commercial pectin - Apple pectin - Citrus pectin Grow It Eat It Preserve It!
Pectin
• •
Amount varies with fruit and degree of ripeness
o
Just ripe fruit has best quality pectin
o
Under-ripe and over-ripe fruit will not gel well Jellies often need added pectin to hold their shape Grow It Eat It Preserve It!
Pectin
• •
Commercial pectin
o
Liquid
o
Dry Advantages
o
Cooking time is set and is shorter
o
Greater yield from same amount of fruit Grow It Eat It Preserve It!
Pectin
• • • •
Store in a cool, dry place Observe “use-by” dates Buy a 1-year supply Modified pectin for reduced sugar products
o
No added sugar
o
Less added sugar than regular recipes Grow It Eat It Preserve It!
Acid
• • • •
Needed for gel formation Provides flavor Higher in under-ripe fruits Add lemon juice or citric acid to increase acidity Grow It Eat It Preserve It!

Use granulated white sugar
• • •
Works with pectin and acid to make gel Acts as a preservative Contributes to taste Grow It Eat It Preserve It!
To reduce sugar
• •
Modified pectin
o o o o
Some need no sugar Others need some sugar May use an artificial sweetener Processed like regular jellied products Regular pectin with special recipes
o o o
Formulated using regular pectin, without added sugar Regular pectin has some sugar Stored for short time in the refrigerator (or frozen) Grow It Eat It Preserve It!
To reduce sugar
• •
Recipes using gelatin
o
Unflavored gelatin thickens product
o o
Can use artificial sweeteners Stored in refrigerator Long-boil recipes
o
Boil fruit pulp for long periods
