How to store jam: terms and optimal conditions, tips for choosing a place and containers

How to properly prepare jam and containers for storage

Proper storage of jam at home is the key to the quality of the product while preserving all the beneficial substances. How to protect your creation from mold and damage? This question is asked by every housewife who values her work.

Experienced specialists have developed basic tips for storing jam:

The most appropriate container for jam should be a glass jar with a volume of 0.5-1 liters.
Before seaming, the container should be sterilized with steam or water.
Filling a wet jar with jam is strictly prohibited. You need to leave it upside down on a napkin until it dries completely. You can also use the method of drying containers in the oven at a minimum temperature.
Choosing the right lid deserves careful consideration. No flaws are allowed on it; the surface must be smooth. White caps are most suitable for screwing due to the least oxidation. You can also use screw-on ones; they are easy to use, easy to sterilize and can be reused. But the ideal solution would be to purchase a set of vacuum lids that reliably protect the product from air penetration.
To protect jam from mold, it is necessary to take into account the level of sweetness of the ingredients. The lid is most likely to swell when there is a large amount of sugar. In this situation, it is necessary to reduce the amount of seasoning added.
The consistency of the jam is also of great importance - the thicker it is, the longer the shelf life.

If short-term storage of jam is required, about 2-3 months, then plastic lids can be used. For greater reliability, tightly close the neck of the vessel with several sheets of parchment.

Choosing a place in the apartment

The most suitable conditions for storing jam are the lower shelves in the refrigerator. The product, prepared in accordance with the instructions, can be stored under normal room conditions. A dark pantry with a temperature of 20 degrees can also be a good option. The cellar is not the best option for storing sweet winter preparations. There is a high probability of freezing or spoilage - rupture of a glass jar due to sudden temperature changes.

Answer to the question

On an insulated balcony, you don’t have to worry about jars of pickles.
If the balcony is not insulated, but is glazed, you can store jam, regardless of whether there is frost or not. The jars do not crack. Only when it comes time to bring the jar into the house, you need to give it time to acclimatize at room temperature. When exposed to frost, jam does not freeze, but quickly becomes sugary.

Jars of cucumbers and tomatoes can be kept on the balcony until frost sets in, and then brought indoors, as the brine may freeze and the jar may burst.

Pickles are preserved well when the temperature is from 0 to +15°C, but if the room is damp, the lids may rust. Moreover, even if the bottle does not crack and the liquid freezes, the taste of the product inside will be lost. As after any freezing, they become soft.

Long-term storage of preserved food is undesirable, even if it is stored correctly. Chemical interactions occur between amino acids, proteins and sugars found in foods.

Subsequently, a dark substance forms on the preservation. It does no harm, but the appetizing appearance is lost.

The most optimal shelf life for preserves and jam is two years. Therefore, it is necessary to cook it in such quantity that it can be stored no longer than this period.

How long can it be stored?

The optimal shelf life of homemade jam is 6-36 months. The storage duration is influenced by various factors - packaging, type and quality of the product. The shelf life is also affected by the method of preparation. Sugar is a natural preservative; in order for the sweet preparation to be stored for a long time, it is necessary to mix the fruits with sugar in equal proportions. Bringing the mixture to a boil increases the shelf life of the finished product several times.

Seedless pieces, cooked and sealed according to instructions, can be stored without problems for up to several years without changing their properties. But the shelf life of raspberry jam is 6-12 months. If the fruits have seeds, then the storage time of the jam is slightly reduced - only up to six months. This is because the core contains a dangerous poison that permeates the contents of the jar.

After 7-8 months, the accumulation significantly exceeds the norm safe for the human body. All sweet products that contain seeds fall into the risk zone. Five-minute jam without heat treatment, which is prepared from fresh berries and fruits, can be stored in the refrigerator for up to 6 months. After opening the jar, desserts without seeds can be stored in the refrigerator for up to 1 month, with seeds - no more than 14 days.

Storage in PVC containers

Long-term storage of jam in plastic containers is not advisable. It can stay in them for no more than 4-6 weeks, after which it should be poured into a glass container or simply eaten. Longer storage will lead to spoilage of the product and the appearance of mold. When stored in PVC containers, the product is quickly saturated with harmful carcinogenic substances.

Plastic containers do not tolerate sunlight or hot temperatures; they quickly crack and burst.

Food containers can contain aromatic jam only if it is a special plastic - polyethylene. These containers are usually labeled PEND or HDPE. Fruit and berry delicacies can exist in plastic containers for a short time, and the container itself should be used for no more than a year, after which it should be disposed of.

Jam cannot be overcooked

Overcooked jam loses its unusual aroma, its color and taste change (unfortunately, not for the better).

Jam cannot be overcooked

How do you know when it’s enough to boil? You can determine the readiness of the jam:

visually - if the jam has become translucent and the foam begins to accumulate in the center of the pan, it is ready;
using simple manipulation - scoop a little jam into a spoon, wait until it cools down, and drop it onto a cold saucer. If the drop remains round and convex, the jam is ready, but if it spreads, then the cooking process is not completed.

Can it be frozen in the freezer?

Fruit or berry desserts are one of the famous delicacies popular all over the world. But besides the traditional version, there is also a more exotic type of product - frozen jam. This dessert will surprise any gourmet; you can enjoy it on a hot summer day instead of ice cream. This is a healing and appetizing type of sweet, consisting exclusively of natural products with a lot of vitamins. Jam can be stored for a long time without changing its taste.

How to freeze:

Wash and thoroughly dry berries or fruits for future jam.
Sprinkle with sugar, 2 parts berries, 1 part sugar.
When the juice appears, mash with a blender until pureed.
Place the mixture in a plastic bag and place in the freezer.

Possible problems

Even an experienced housewife may experience a situation where the preserved food begins to ferment, the jar cracks or the lid swells.

Candied

Candied jam indicates that too much sugar was added during cooking or simply overheated.

This is not a problem, he can be rehabilitated. There are several options for this:

Place the container with the sweetness into a deep bowl of water. After boiling, leave the mixture on low heat until the sugar is completely dissolved.
Add 50 ml of hot water to the jam per 1 liter of finished product. Boil for 5 minutes.

Such sweets should be consumed as soon as possible, because long-term storage is contraindicated for them.

Mold

Even if a small area is affected, there is no doubt that the entire product is infected. Most often you can observe a similar situation in jam, tomato paste, and dairy products. Methods for dealing with this unpleasant substance are not complicated. Heat treatment, unfortunately, will not bring the desired result. High temperature will have no effect on the toxins, so there is no point in decontaminating contaminated food in the microwave. The best option would be to completely get rid of the damaged product.

Fermentation

Unfortunately, even experienced housewives have incidents with home preserves. And it seems that the necessary standards and instructions have been met, but the lid is swollen or a strange smell is heard from the finished product. The situation can be easily corrected. First, using a colander, you need to strain the contents of the jar, separating the juice from the berry mass. After this, add 200 g of sugar per 1 liter of liquid and boil.

When the syrup holds its shape, place the berries in a bowl and simmer for 20 minutes.

Harm of jam

If consumed excessively, the benefits of jam can easily turn into harm.

The high sugar content in jam has a negative effect on tooth enamel, contributing to their destruction and the formation of caries.

Persons predisposed to allergic reactions are advised to use jam with caution, since many fruits and berries are strong allergens. Allergy sufferers should also be careful if honey is added to the jam instead of sugar. Most often, sugar is added to jam, which increases the number of calories.

In this regard, people suffering from obesity or diabetes should consume jam only in moderate quantities.

Features of storage of some types

How to protect dessert from spoilage in winter and protect it from negative influences? A moment that worries every housewife.

Cherry with pits

The shelf life of jam depends on an important factor - location. The correct location of the finished product is a refrigerator with a temperature of +10°C.

To increase the shelf life of cherry jam with pits, you need:

Open cans of last year's dessert.
Pour the syrup into a separate container.
Remove seeds from berries.
Combine the fruits and liquid, bring to a boil over low heat, and simmer for several minutes.

A lower temperature will not benefit the berry dessert, and may also damage the jar. Cellar conditions are suitable only if the temperature is kept at +10 °C.

Apricot

Proper storage of apricot jam implies the following conditions. The most preferable place is a basement, cellar or refrigerator. If there are no suitable options, then you can prepare a fruit dessert by mixing berries and sugar in equal proportions. In this case, you need to add a little juice and zest of one lemon.

If the jam has spoiled, the moldy product should be disposed of immediately to avoid poisoning.

From pine cones

A healing dessert made from pine cones should be stored only in the correct container - glass jars, sterilized and completely dry. The best place is the refrigerator. You can use a dark and cold room without direct sunlight. The acceptable temperature for cone jam is 0-20 degrees and humidity up to 70%.

From black currant

Currant delicacy can be stored for 1-2 years at a temperature of +6-12 degrees. Under room conditions, the shelf life is 1-3 years. The pantry will allow you to store jam at a temperature no higher than +20 degrees. Storing the product in the cellar is not recommended.

With gelatin

Adding gelatin to accelerate hardening allows the jam to perfectly retain its shape and jelly-like consistency even at room temperature. Therefore there is no need to refrigerate. A cool place - a cellar or basement - is suitable for storing berry treats.

Cans of sweet mass prepared in this way do not explode.

What containers are still possible?

Storing jam in bottles is allowed, but only for a short time. Jam can only be poured into plastic bottles when it is cold.

For this purpose, you can use PET bottles (from lemonade). This option is the last one. There is a high probability that at the slightest fermentation, the released alcohol will react with harmful substances from the plastic.

In such a container, sweets can only be transported. Preserving the taste of jam is only possible when using glass jars.
