Today it is impossible to imagine life without food. They are an integral part of our life, therefore, for their long and safe storage, mankind is gradually inventing more and more new containers. And despite the fact that aluminum cans are a development of past centuries, they, oddly enough, are the most suitable for storage and convenient transportation of such products. How are they unique and special? Let's look at this in today's article.
What are they?
Probably, each of us has been familiar with the shape and design since childhood: a large steel barrel of cylindrical shape, on top of which there is a lid and a neck. Such aluminum cans can be seen in almost all farms, and even in our village grandmothers they are widely used. True, the dimension of these containers is significantly different. For example, in a farm it’s enough to use a 5-liter barrel, but in industry, a larger volume is used. Most often it is an aluminum can of "40 liters". The price for them is on average about 1.5-2 thousand rubles. Simple 5-liter containers can be purchased at almost any hardware store, and they will cost no more than 500 rubles.
Why not plastic?
Polyethylene containers are now widely used in almost all sectors of the economy, however, if this area concerns products, it is important to remember the following. By its properties, plastic does not like direct rays, so if you put such a container of milk for 5-10 minutes in the sun with a 30-degree heat, there is a big chance that it will simply turn sour. Milk aluminum cans, in addition to being made from a material that is absolutely not harmful to food products, have double walls, most often filled with air. This is usually a model with a volume of more than 10-15 liters. They have neither direct transmission of sunlight, nor much heating at high ambient temperatures. Thus, aluminum cans are ideal for transporting perishable products.
What can be stored in them?
If you think that only milk can be stored in such containers, you are deeply mistaken. Aluminum cans are ideal for storing a range of products such as:
- sour cream;
- Birch juice;
- honey;
- vegetable or sunflower oil.
In addition, alcohol or even gasoline can be transported in such barrels. True, if the latter fell into such a can, you are unlikely to pour fresh milk into it, even if you boil such a container 10 times. This is fraught not only with food poisoning, but also possibly with chronic diseases. Therefore, use separate containers for petroleum products and milk.
In conclusion, we note that if you constantly use such a can to transport lactic acid products, wash it periodically, even if you pour milk after sour cream. It is not necessary to use any acidic or other aggressive cleaners.
