Harm and benefits of semi-finished products
The modern rhythm of life, especially in the city, forces many not to waste time on cooking and using semi-finished products. If a person has to spend most of the day at work, then there is no time to stand at the stove in the evening, and sometimes he is lazy. Today, semi-finished products make up a large part of the urban dweller's diet. It is convenient to go to the nearest supermarket on the way from work and choose what you want more today, and when you come home, cook a full dinner in half an hour. Blanks are also used in the catering system. The huge variety of such products in stores allows you to choose different options every day — for breakfast, lunch or dinner.
Semi-finished products usually include any food products that have been pre-processed to various degrees, prepared for long-term storage and making it possible to quickly cook food.
Product processing
According to its principle, the pretreatment of products is divided into mechanical, hydromechanical, thermal, chemical and biochemical.
The shelf life of processed products depends on the technology that ensures the safety of their nutritional parameters and taste value. These can be various types of canning — salting or pickling, drying or drying, pasteurization, the use of vacuum packaging and others. But the most popular among manufacturers of semi-finished products is the shock freezing technology.
If no artificial colors, preservatives, chemical flavors or other harmful ingredients were used in the pretreatment process, it does not reduce the usefulness of the food. Most frozen blanks produced by large companies undergo industrial processing and their shelf life in frozen form is quite long — up to six months.
The range of such products is very wide. These can be:
- dumplings and dumplings with meat, potatoes and mushrooms;
- manti, khinkali and chebureks;
- cabbage rolls;
- pancakes with meat and sweet fillings;
- meat, chicken and fish cutlets.
Most often, such products are brought to semi-readiness and it is enough to subject them to a short heat treatment (cook, fry or reheat in a microwave) to get not only healthy and nutritious, but also delicious food.
Shock freezing is the process of freezing food to -18 ° C for a minimum period of time (usually no more than 4 hours). The high cooling rate is ensured by an extremely low temperature in the chamber (below -30 °C) and intensive product blowing.
At the same time, ice crystals in fractions containing moisture are formed much smaller than with conventional smooth freezing. As a result, the structure of the fresh product is not disturbed. Due to the speed of shock freezing, the periods of possible development of the bacteriological environment are reduced and there are no traces of vital activity of various types of bacteria.
Due to the rapid freezing, the process of moisture evaporation is prevented and aromatic and nutrients do not have time to leave the product. This preserves its nutritional value and taste qualities. The shelf life of shock-frozen products is significantly longer than that of products cooled in conventional chambers.
According to statistics, the demand for semi-finished products frozen using this technology is growing on average by more than 5 percent every year.
Harm and benefits of semi-finished products
Semi-finished products have their adherents and, of course, their opponents. Both are trying to convince each other that they are right. The debate about what is harmful to semi-finished products can go on indefinitely, especially if subjective arguments are given as arguments. Let's try to list all the pros and cons with maximum objectivity.
Disadvantages of semi-finished products
Speaking about the dangers of semi-finished products, it is important to understand what they are made of and how they are made. Many manufacturers, in order to save and simplify the technological process and increase the shelf life of the product, replace natural ingredients in the formulation with all kinds of artificial additives. It is a stretch to call such products high-quality, and then only if the additives do not harm the consumer's health.
The next disadvantage is the high calorie content. This is especially true for semi—finished meat products, which can add a lot of fat and low-quality meat components - skin, cartilage and offal. Such food cannot be classified as dietary in any way. The amount of cholesterol in it can be so high that it will negatively affect the condition of a person's blood.
The lack of information on the packaging about which proteins and fats the manufacturer used in the product also does not contribute to the popularity of frozen semi-finished products. Large companies that care about their reputation, as a rule, do not allow themselves to use cheap vegetable proteins in the production of meat and fish products, which are inferior in amino acid composition to full-fledged animal proteins. For people who control their weight, this can be extremely important.
Another drawback of culinary semi–finished products is flavoring additives and high salt content. Table salt itself is a preservative and at the same time a flavor enhancer. It, along with seasonings and flavors, can be added to the final product to hide the taste flaws of the semi-finished product. For the human body, excessive salt intake can cause fluid retention in the body, the formation of edema and stress on the kidneys. In addition, salt and spices irritate the gastric mucosa and can lead to the development of gastritis.
It is recommended to bring many industrial semi-finished products to readiness by roasting. If the consumer is extremely scrupulous about his weight or has intestinal diseases, it is better to cook semi—finished products in other ways - stew, boil or bake without oil.
Advantages of semi-finished products
If we talk about the benefits of fast food, then their main advantage is saving time. Busy people and travelers prefer to cook just such food. In addition, you can add another advantage of semi—finished products - simplicity and ease of preparation. Even if you completely lack culinary skills, with the help of frozen semi-finished products, you can prepare a full breakfast, lunch or dinner not only for yourself, but also for your loved ones.
Adding fruits, vegetables and berries to the diet will help you get vitamins that are so necessary for the body in winter. Shock freezing technology allows you to save 99% of the nutrients in the products. The use of frozen semi-finished products will help provide additional vitamins and add variety to the preparation of delicious and nutritious dishes, even for those who are on a diet.
You should not eat only semi-finished products, but if you cannot do without them at this time, give preference to trusted manufacturers when choosing products. In stores, be sure to study the label in detail, where it should be indicated from what raw materials the product is made, as well as the method of freezing and expiration date.
Pay attention to the products of the "Lina Home Products Factory" under the brands "From the heat of the moment" and "Well-fed Dad", which you can always find in any supermarket. The company guarantees the absence of chemical preservatives, soy and other additives in their composition. The product range includes a wide variety of semi-finished products for every taste.
