How to Preserve Corn?
Summer is the ripening season for everyone’s favorite corn. Delicious boiled sweet corn is enjoyed by both children and adults. There is a great way to enjoy this flavor even in winter — preserve corn in an autoclave. We will tell you all the details of this process.

Useful properties
Corn is not only tasty, but it is also a product that contains many beneficial substances and vitamins necessary for humans all year round. Corn contains vitamins C, B, E, and elements of zinc, magnesium, manganese, and phosphorus. This beneficial set has a positive effect on human health, in particular:
- normalizes blood sugar levels;
- has choleretic and diuretic properties;
- reduces cholesterol;
- boosts immunity and positively affects heart function;
- improves digestion;
- reduces the risk of developing rheumatism;
- improves lactation during breastfeeding.
To preserve the maximum amount of these nutrients, choose an autoclave from the company “Ukrpromtekh” and preserve your favorite product without unnecessary effort.

Tips and Warnings
There are no special requirements for preserving corn. Almost all varieties will do, but it is best to choose sweet corn with a rich flavor. The most important criterion is the age of the corn — it should be ripe but not too old so that the kernels are not hard. However, this is not a critical factor. Overripe corn will simply take longer to cook.
Canned corn can be stored for 3 years in a room where the temperature does not exceed 25 degrees, and the relative humidity does not exceed 75%. An opened jar of corn should be stored in the refrigerator for no more than three days.
The Simplest Recipe for Canned Corn
We need a minimum of ingredients to prepare:
- corn;
- salt — 1 tsp/jar;

Preparation:
- The corn cobs must be peeled of green leaves and thoroughly washed.
- There are two methods of pre-processing corn for canning:
