How does jam making preserve the fruit

These products do not have sugar as their preservative and must be processed or stored as directed. Some need longer processing in a boiling water bath and some need refrigeration.

Special Modified Pectins: This is a quick, easy way to make lower sugar jellied products that can be stored on the pantry shelf until opened. These pectins are not the same as regular pectin. Specific recipes and directions are listed on the package insert. Follow these carefully for the brand of pectin you are using.

Regular Pectin With Special Recipes: These special recipes have been formulated so that no added sugar is needed. However, each package of regular pectin does contain some sugar. Artificial sweetener is often added. Recipes Using Gelatin: Some recipes use unflavored gelatin as the thickener for the jelly or jam.

Long-Boil Methods: Boiling fruit pulp for extended periods of time will make a product thicken and resemble a jam, preserve or fruit butter. Artificial sweetener may be added. Remake a trial batch using 1 cup of jelly or jam first. Measure jelly or jam to be remade. Heat the jelly to boiling and boil until the jellying point is reached. Remove jelly from heat, skim, pour immediately into sterilized hot containers and seal and process for 5 minutes.

Stir the package contents well before measuring. Mix the pectin and water and bring to a boil, stirring constantly. Add jelly or jam and sugar. Stir thoroughly. Bring to a full rolling boil over high heat, stirring constantly. Adjust new lids and process in a boiling water bath for at least 5 minutes or for time specified in the recipe. Place jelly or jam in a saucepan and bring to a boil, stirring constantly.

Quickly add the sugar, lemon juice and pectin. Bring to a full rolling boil, stirring constantly. Boil hard for 1 minute. Remove from heat. Wipe jar rims. Adjust new lids and process in a boiling water bath for 5 minutes. Stir well until sugar is dissolved about 3 minutes.

Pour into clean containers. Cover with tight lids. Let stand in refrigerator until set. Then store in refrigerator or freezer. Stir well until dissolved about 3 minutes. Place in small saucepan and place over low heat, stirring, until the powdered pectin is dissolved. Add to the sugar and fruit mixture and stir until thoroughly blended about 2 to 3 minutes. Why should cooked jelly be made in small batches? If a larger quantity of juice is used, longer boiling is needed causing loss of flavor, darkening of jelly, and toughening of jelly.

Should jelly be boiled slowly or rapidly? It should be boiled rapidly since long, slow boiling destroys the pectin in the fruit juice. Discard all of the product. Why did my jellied fruit product ferment, and what do I do? Jellied fruit products may ferment because of yeast growth. This can occur if the product is improperly processed and sealed, or if the sugar content is too low.

Fermented fruit products have a disagreeable taste. Discard them. Table 1.

One final note on jams. Too much stuff in one pot means it will take longer to boil, changing the flavor of the jam and effecting the way the pectin sets up.

Her love for cultural cuisines was instilled early by her French Canadian Grandmother. Her experience in the kitchen and in recipe development comes from years working in professional kitchens. She has traveled extensively and enjoys bringing the flavors of her travels back to create easy-to-make recipes. Hi Desiree. Honestly, I never peel my apricots to make the jam. If you are sensitive to textures or want a more smooth jam, then you may want to consider peeling them.

Thanks for spelling out the basics from Jelly to fruit butters. When I posted this on my facebook page I got an immediate response! Beautiful photos and step-by-step instructions.

Fruit Butter. The Process Prep the Fruit: Wash your fruit. Once the fruit has come to a boil, add the sugar and stir until it has dissolved. Be sure to stir your jam thoroughly and to take the temperature from the center of the mixture to be sure you are not in a hot pocket. Freezer test — While your jam is cooking, place a small plate in the freezer. Once your jam starts to thicken, spoon a small amount of the mixture onto the plate and place it back into the freezer for 1 to 2 minutes.

Remove the plate from the freezer and press the pile of jam. If it wrinkles, the jam is done. As an added test, you should be able to trace your finger through the center of the puddle of cooled jam, and the jam should stay put.

Spoon or sheet test — Dip a cold metal spoon into the boiling mixture. Away from the heat, tilt the spoon, so that the mixture runs off the side. If the mixture is not quite jelled, the liquid will flow off the spoon in a stream. As your jam starts to set, the stream will become drops that get progressively thicker.

When mixture slides off of the spoon in one sheet instead of drops, it has reached the jellying stage. What kind of jam will you make first?

For successful products, use pectins as directed and do not exchange one type of pectin for another. Measure ingredients exactly to ensure a quality product.

Prepare one batch at a time. Doubling a recipe may prevent proper jelling. Purchase fresh pectin each year. Old pectin may result in poor gels. Preservative may be included in commercial pectin to prevent microbial spoilage of the finished products. Commercial Pectin: Pectins are grouped by type: regular or modified pectin.

Be sure to follow the directions from the manufacturer. Modified pectins are available for home use to make reduced calorie jams and jellies. No-cook jams and jellies may be made with most pectins, both regular and modified pectins. No-cook preserves must be stored in the freezer until use. After opening, they can be stored in the refrigerator up to three weeks.

Measure ingredients carefully. Gelatin: Gelatin, a protein substance derived from collagen, may be used as a thickener in refrigerator fruit spreads.

Products made with gelatin must be refrigerated and used within one month. Unflavored gelatin does not contain pectin.

Artificial sweeteners can be used with refrigerator jam and jelly recipes made with gelatin. ClearJel is not recommended for jams or jellies. When using either method, make one batch at a time, according to the recipe. Increasing the quantities of the ingredients often results in soft gels. Stir constantly while cooking to prevent burning.

Recipes are developed for specific jar sizes. If jellies are filled into larger jars, excessively soft products may result.

Even though sugar helps preserve jams and jellies, molds can grow on the surface of these products. Research shows that the mold which people usually scrape off the surface of jellies may not be as harmless as it seems. Mycotoxins have been found in some jars of jelly having surface mold growth.

Mycotoxins are known to cause cancer in animals; their effects on humans are still being researched. Because of possible mold contamination, paraffin or wax seals are no longer recommended for any sweet spread, including jellies.

Correct process time at higher elevations by adding 1 additional minute per 1, feet above sea level. If nonsterile jars are used, the filled jars should be processed 10 minutes. Use of sterile jars is preferred, especially when fruits are low in pectin, since the added 5-minute process time may cause weaker gels.
