Production technology at the plant
The production of canned corn is a sequential process that includes:
- Acceptance of the product. At this stage, corn is delivered from the fields to factories, where it is sorted into varieties, and grains that are not suitable for canning are disposed of.
- Cleaning. Leaves and threads are removed from the cobs, after which the grains are trimmed and sent for washing. There the grain is washed, cleansed from small impurities and shells.
- Inspection. After washing, the grain falls onto a conveyor belt, where damaged grains are manually or automatically selected.
- Blanching and cooling. Blanch the grains at a temperature of 90 °C for 5 minutes for premium corn and 7 minutes for first grade corn. At the end of this stage, the grains are cooled with cold water.
- Preparing the fill. Corn filling is prepared according to a unique recipe.
- Packaging and capping. Corn and bay are sent to cans for preservation, after which they are sealed using sealing machines.
- Sterilization.
- Control. After sterilization, mandatory quality control is carried out at a frequency of one jar per hour.
Types of Canned Corn
Depending on the form in which the product was canned, canned sweet corn is distinguished:
- on the cob;
- from whole grains;
- crushed.
In addition, canned corn is divided into varieties:
- highest (no more than 20% of mechanically damaged grains are allowed);
- first (no more than 40% damaged grains are allowed).
How to choose?
You can choose tasty and high-quality canned corn by studying the following characteristics:
- Exterior of the can. The tin can must be intact, without dents or deformation. When damaged, copper and tin begin to be released from it, which can pass into the corn.
- The glass jar must be clean, without stains or traces of leakage or rotten product.
- Label. It must be clean and evenly pasted (this indicates that the production, transportation and storage of the can was carried out in accordance with the standards).
- Production information. High-quality corn must comply with GOST. According to the rules, the composition should include only corn, sugar, salt and water.
- Best before date.
After opening the jar, the quality of the corn can be judged by the grains: they must have the correct, uniform shape, have a natural color and a pleasant, sweetish aroma. If the grains are irregular in shape, have dark spots and are not packed tightly, the quality of the canned corn is considered low.
In stores, corn is sold not only in tins, but also in glass jars, so the question arises: “Which one is better to buy?” You should opt for corn in a tin. The fact is that processing grains in tin packaging requires less time, and the can itself heats up and cools faster, which allows you to optimize the production process, improve taste and retain more nutrients in the product.
How to choose the right canned corn
Large chain stores usually offer a wide range of canned corn from different manufacturers. At the same time, you can find trademarks not only from Russia, but also from Hungary, Poland, China, Thailand, Moldova and Belarus.
It is interesting that the world-famous French company Bonduelle currently not only supplies the Russian market with its own canned vegetables grown in the south of Russia (Kuban, Krasnodar Territory), but also often fulfills orders to produce products for other brands (Globus, “ We eat at home”, etc.).
Therefore, when choosing canned food, you should focus not only on well-known brands or price levels, but also on a number of objective criteria that are the same for all canned corn grains.
- Firstly, you need to pay attention to the expiration date (the date must be applied with indelible paint on the iron parts of the tank) and the absence of deformation of the jar. In this case, it is worth choosing canned food produced in the fall or summer, when the corn ripens. Grain made from pre-dried raw materials ends up in jars that are screwed at other times (this applies to European and Russian producers).
- Secondly, you should trust products that are marked with GOST. After all, the requirements of the standard recommend the presence in canned food only of grains, water, salt and sugar in certain proportions and of appropriate quality.
- Thirdly, you must carefully read the composition indicated on the packaging. Carbohydrates should not exceed 11-12 g per 100 g. If this threshold is exceeded, the dish contains too much sugar, which affects the benefits of consumption.
- Fourthly, you can shake the jar slightly to make sure that the amount of grains in relation to the liquid is normal. Sometimes manufacturers add more water than required by the standard and there is a risk of buying liquid at the price of grains. If the jar gurgles too much when you shake it, it's best to leave it on the shelf.
How to store?
Storing canned food seems simple. © https://ydoo.info/product/konservirovannaya-kukuruza.html However, you should remember the terms and conditions for storing products.
Conditions
You can store canned corn either in the refrigerator or at room temperature. For a closed tin can, temperatures up to +25 °C are suitable. A glass jar should be stored exclusively in the refrigerator, but for a tin jar, both a refrigerator and a kitchen cabinet are suitable.
Term
Under proper conditions, the shelf life of corn in a tin can is 3 years, and in a glass jar - no more than 2 years.
If the can was opened
If the can has been opened, it is best to use the corn right away. If there is a need to preserve leftovers, the open jar can be placed in the refrigerator, but the shelf life of corn there is only a day.
Can it be frozen?
Unused corn can be frozen. Before putting it in the freezer, you need to drain the remaining liquid and dry the grains thoroughly with a paper towel. After this, transfer the corn kernels to a plastic bag or plastic container and place in the freezer. The shelf life of the product under such conditions is about 6 months.
Frozen corn contains fewer nutrients than it originally had, although the taste does not disappear.
What kind of corn is harvested?
For preservation, the most ripe and juicy corn is selected. Firstly, it must belong to the sugar type, which has the largest amount of vitamins and minerals. And secondly, it must have a milky-waxy state. You can check this this way: if, when pressing on a grain of corn, splashes of milk appear and pulp comes out of the grain, then this is corn of the required ripeness, ready for preservation.
You should pay attention to the condition of the grains on the head of cabbage: they should be the same size, shape and color, without dark spots or mechanical damage.
You can judge the ripeness of corn by its leaves. If they are dry, it means the heads of cabbage have been stored for too long, but leaves that release juice when pressed indicate the ripeness of the corn.

How to preserve at home?
Home-canned corn is an incredibly tasty and healthy product that can be enjoyed all year round.
Grains
To preserve corn kernels, take several ears of corn and peel them from the leaves. Then use a sharp knife to cut off the grains as close to the surface of the cob as possible. In this way you need to prepare 2 kg of grains.
The grains are placed in a deep pan and filled with cold water so that it is 3-4 cm above the level of the grains. Place the pan over high heat, bring the water to a boil and remove the resulting foam. After this, reduce the heat to low and cook the corn for another 60 minutes.
After the specified time, remove the pan from the heat and drain the liquid into a separate container. Glass canning jars are sterilized and corn is placed in them, filling the jars ¾ full. After this, the marinade is prepared: the liquid obtained during the cooking process is mixed with salt and sugar, maintaining a proportion of 2 tbsp. l. salt and 6 tbsp. l. sugar per 1.5 liters of liquid. The marinade is boiled and then poured into jars with corn.
The next stage of preparation is pasteurization. To do this, cover the jars of corn with a lid and place them in a pan of hot water.
Pasteurization begins from the moment the water boils and lasts 60 minutes. After this, the cans of corn are rolled up, turned over and wrapped in a warm blanket.
When the canned food has cooled, they are sent for storage in a dark and cool place where the temperature does not exceed +10 °C. A cellar or refrigerator shelf will do. The shelf life of home canned food is 1-2 years.
Corn on the cob
You can preserve corn not only in grains, but also in whole cobs. To do this, they are cleared of leaves, threads and slightly trimmed with a knife at the base. Fill the pan with cold water, lower the cobs into it and cook for about 10 minutes. After the specified time, remove the pan from the stove, drain the water and cool the cobs.
Place the corn in 3-liter jars and pour boiling water over it. After 3-5 minutes, the water is poured into a saucepan, boiled and poured into jars again. These steps are repeated 3-4 times, and then 3 tbsp is added to each jar. l. 9% vinegar, bay leaf, 2-3 black peppercorns and add marinade. It is prepared like this: mix a liter of water with 2 tbsp. l. salt, 1 tbsp. l. sugar and boil the liquid.
The jars are rolled up, turned over and wrapped in a blanket, and then stored in a dark, cool place.
