Milk is the most amazing product presented to us by nature. Rural residents have the opportunity to use it immediately from under the cow. But the townspeople buy a useful and indispensable product in the store. This milk must undergo heat treatment, which extends the shelf life of the product. This article will focus on milk sterilizers: their structure and purpose.
The benefits of milk
From the very first birthdays, a person eats milk, first breast-fed, and later cow-fed. This product is rich in vitamins and minerals, enzymes and proteins, milk fats and sugar. Useful substances are easily absorbed by the human body.
Milk is especially useful for babies, because protein is so necessary for the structure of muscles, skin cells, nails and hair. For the intestines to function properly, the body must have enough milk sugar. It helps to normalize the microflora, removing purulent foci and infection. Milk saturates the body with calcium, which nourishes bones, teeth, and promotes the production of hormones and enzymes.
The product contains many vitamins that contribute to the normalization of all life processes in the human body. The nervous system calms especially well, stress is relieved, and depression disappears.
Periodic table in the composition of milk
This healthy and tasty product is rich in minerals: calcium and potassium, magnesium and phosphorus, sodium, chlorine and sulfur. All of them relate to macrocells. The greatest value in milk is calcium. It is easily absorbed by the human body. For example: cow's milk contains one hundred and one hundred and forty milligrams of an element per percent of the product. The amount of calcium in milk is directly related to the diet of the animal, its breed. The stage of lactation and the season are of importance. So, for example, in summer there is less calcium in milk than in winter.
Milk is beneficial in micronutrient content. Their concentration is low, hence the name. This group of minerals includes copper and iron, manganese and zinc, iodine and cobalt, aluminum and fluorine, selenium and silicon, chromium, lead, chromium, tin and others. They are part of vitamins and enzymes. The amount of these minerals in milk depends on water, soil, the composition of nutrient mixtures for animals, their health status, processing methods and storage conditions of the product. With a set of elements for almost the entire periodic table, can milk be not healthy? Of course not. Milk is the very first food. People consume milk throughout their lives.
Which sterilizer to choose: steam or cold?
With the advent of the baby in the house, there is a need to often boil nipples, bottles, toys. They deteriorate quickly from this, and the method of cleaning accessories is not very convenient: you need a pan, trays, and pot holders. For this, there is a specially designed device that is simple and easy to use. It is a milk sterilizer. Having become acquainted with the parameters of devices, everyone will choose the best for themselves. Sterilizers are:
- Ordinary steam. They are used when you need to clean the nipples, bottles and metal utensils. At the heart of the action is hot steam.
- Steam for microwave. This heated appliance is used to clean dishes and accessories. Here, the microwave power is used to heat the water.
- A milk sterilizer that uses a cold disinfectant to process. It can be used without being plugged in.
When purchasing a sterilizer, a passport is always enclosed in the packaging box indicating the technical characteristics and parameters of the device. You need to pay attention to the following:
- How many bottles fit.
- The presence of a time indicator. Without it, you have to constantly monitor the process.
- Possibility to sterilize other accessories.
- Device power. Models with different sterilization periods are produced: from five minutes to twenty.
Home Milk Sterilizer
This device is intended for heat treatment. Sterilized milk is cleaned of pathogenic bacteria and germs. They simply die due to exposure to high temperatures. The disadvantage is that in sterilized breast milk, some of the nutrients necessary for the formation of the baby's immunity are lost. Therefore, heat treatment is not recommended to be used constantly.
Sterilize milk for the baby only if necessary. For example, a woman who has given birth does not have her own milk or is not enough. Then the donor product is necessarily processed. A sterilizer for breast milk at home is very simple. To do this, it’s enough to adapt a large enameled pan, prepare glass or plastic bottles. The procedure is as follows:
- Breast milk is bottled.
- The pan is filled with water so that the container is stable, does not swim in the water and does not fall.
- Gas or electric stove turns on. The pan is set on fire, the water is brought to a boil. Then the heating decreases, and boiling continues. Five to eight minutes is enough.
- The stove turns off.
- Bottles are carefully removed from the pan using a towel so as not to burn yourself.
Sterilizer for baby food
Installing Babymoov is an indispensable tool for any mom. This milk sterilizer for children is endowed with holes for supplying steam not only on the central tube, but also on bottle holders, which have removable mechanisms. If necessary, you can handle breast pumps. The central part of the installation is also removed, on it you can dry the container. As you can see, these operations are done without touching the dishes with your hands. The installation holds six bottles with nipples on them. By the sound of a signal you can find out that the sterilization is over. Philips sterilizers are also very popular, although they are quite expensive. There is also an alternative - Belarusian Buslik sterilizers, which many mothers are happy to purchase, since their quality is not bad, and the price is more than affordable.
Product Processing Methods
Sterilized milk is a sterile product. It does not have bacteria present in the raw product, due to which the shelf life is extended and the taste is not changed. There are different ways to sterilize milk:
- One-step. It is used to make sterilized milk in bags. The product is heated to a high temperature - one hundred forty - one hundred and fifty degrees in one second. Then it is cooled, homogenized and poured into sterile bags.
- Two-stage. This method is used when glass containers are not used as packages. The milk is heated to the same temperature as in the first case, only they can withstand five seconds, and not one. The product is cooled, poured into glass containers and sterilized again. But the temperature is lower - one hundred and twenty degrees, and the processing time is longer - twenty minutes.
In the production of sterilized milk in the first way, the biological value of the product is better preserved. The taste of milk is no different from fresh.
Technology for the production of sterilized milk
- Raw materials are being prepared.
- Milk is normalized - fat content is reduced to a single figure.
- Homogenized - the consistency must be uniform so that the cream does not peel off.
- Salt stabilizers are introduced.
- Sterilized - the heating temperature is one hundred degrees and above.
- Cools down.
- Spills instantly.
Why are salt stabilizers needed? They control acidity. Their presence in milk does not allow the product to sour for a long time - six to eight months. There is a concept of a buffer zone. If it takes lactic acid, the product will turn sour very quickly. The salts dissolve and forcefully fill this void, preventing the acid from entering the product.
For processing in an industrial environment, a milk sterilizer is used. The process is carried out under conditions of absolute sterility. For the filling of this particular product, closed installations are used to prevent microbes. The packaging is tight, therefore milk is insured against the harmful effects of the environment.
A device for processing milk at the place of milk production
A milk sterilizer for the farm is needed in every farm where livestock are raised. The product is sold for sale to the public after special processing. But, if there are newborn calves on the farm, the first time after birth they are given milk. First it needs to be processed so that the kids do not become infected. Use a light milk sterilizer for mini-farms "CCM".
It is a gas discharge lamp with a powerful stream of ultraviolet rays. There is no ozone exhaust, which prevents milk fat from oxidizing, as a result of which milk has no unpleasant odor. The sterilizer is working from the network. Its warm-up time is four minutes. It must be taken into account in the process of work. To verify that the milk sterilizer is ready for use, some red object is brought to it at a distance of one meter. If it turns brown, the device is ready for use at full power.
The sterilizer in the jar is placed so that it does not touch the surface of the milk, which must be constantly mixed. At intervals of ten minutes, samples are taken using a masttest. When he shows a negative reaction, milk is ready to feed the calves. The ultrasonic milk sterilizer is widely used for processing milk on modern farms.
Tubular sterilizers
These units are designed for the heat treatment of milk, cream, various juices. They are used in industrial production, where it is necessary to carry out long production cycles. The standby time on the milk sterilizer takes a short period of time, and the product retains its beneficial properties. These sterilizers are characterized by a high level of sanitation, good thermal productivity, low cost of maintenance, which is of no small importance on the scale of production.
Benefits of Tubular Sterilizers
- There is no possibility of infection by pathogenic microbes.
- It is easy to take a sample to check for product readiness.
- Flushing the installation with a solution is carried out automatically. The control panel is equipped with switches for washing time, temperature, dose of concentrates and others.
- All production lines are automated, which ensures full sterility.
Milk-borne diseases
This product a person receives from animals. If they are healthy, there will be no harm even from consuming fresh milk. But if the animals are sick, the probability of infection is high. A person can get tuberculosis, foot and mouth disease, brucellosis, or coccal infections. That is why it is so important to sterilize milk. Thanks to this procedure, the product is cleaned of germs and bacteria, while maintaining its valuable properties.
