Comparison food Containers

— Container. In this case, containers are understood as fairly simple vessels, designed mainly for the storage and transportation of food and supplied one in a set. However, such models may have various additional functions (see below), sometimes quite extensive. However, anyway, the main compartment in such a container does not have partitions, so the containers are mainly designed to carry homogeneous products (or several types of food that are not afraid of contact with each other and partial mixing). However, there are also models with several compartments; however, unlike lunch boxes(see below), in containers these compartments are usually stacked on top of each other.

— Set. As the name implies, the set includes several containers at once (at least 2). Usually, these are classic containers (see above) of different volumes, and sometimes even proportions (for example, some are low, others are elongated in height). The owner of the set has at hand several trays of various capacities at once, which allows him to choose the best option depending on the situation — including packaging a large amount of food, for which one container is not enough. At the same time, many sets can be "packed" according to the principle of a nesting doll — a smaller container inside a larger one — which makes them quite convenient to store. The specific number of items in the kit may vary, see below for more details....

— Launch Box. The name of such containers literally translates as "lunch box", and it describes well their main purpose — carrying lunches taken "to go" from home to school, work, etc. In addition, a lunch box usually also plays the role of dinner utensils — the design allows you to comfortably eat directly from such a container. The main difference between a lunch box and a regular food container (see above) is the presence of several compartments located next to each other and separated by partitions. Thanks to this, you can load different types of products inside without fear that they will mix; and to access all the content at once, just open the lid. In addition, in some models, the compartments are made in the form of removable containers, which gives even more opportunities — for example, you can not heat the entire lunch box in the microwave, but only part of its contents. But lunchboxes are not suitable for long-term storage of food: the compartments are not hermetically sealed from each other, and products can be “saturated” with smells from neighboring compartments, which worsens the taste and can lead to premature spoilage.

— Heated Lunch Box. Lunch boxes with a heating function provide an opportunity to provide a person with hot home-cooked food in the office or during long car trips. The heating element in their design is usually placed at the bottom. The internal space of the lunch boxes is divided by one or more partitions, and there can also be a separate container with a lid for salads and desserts, which can be removed before heating. Depending on the model and power level, the reheating time for lunch is between five minutes and half an hour. There are models powered by a standard household outlet and a car cigarette lighter socket.

The total number of individual containers supplied in the set (see "Type").

The more containers, the greater their diversity and the wider the choice of the user. At the same time, the variety can be not only in terms of volume, but also in proportions, and even in shape: for example, in sets of 5 items or more, there can be “high” and “low” containers, square containers can be combined with round ones, etc. .P.

It is worth remembering that “a lot” does not always mean “good”: an extensive set may require a lot of space, and it will cost accordingly. Therefore, when choosing, it is worth considering the real needs.

The volume of the smallest container included in the set (see "Type"). In fact, there are quite a few situations when you need to pack a small amount of food, and a large container is not required. On the other hand, if the set is planned to be used regularly for numerous products, then perhaps the smallest tray should be quite large. See "Maximum Volume" for details on specific volumes.

The largest volume of the container supplied with the kit. For sets (see "Type") in this case, the capacity of the largest container is indicated, for all other types — the actual nominal volume. Useful volume may be somewhat less, because. not all containers and not in all cases can be stuffed “under the very lid”. However, this difference is small, and this figure characterizes the capacity of the product well.

Estimating the amount of food that can fit inside, we can proceed from the fact that 1 liter of volume approximately corresponds to 1 – 1.2 kg of soup or a tightly packed product (for example, mashed potatoes) or 700 – 800 g of food, divided into pieces and not packed very tightly (for example, fried potatoes or salad). A large container takes up more space, and too little food can hang around inside, which usually does not contribute to safety. Therefore, too large a volume is just as undesirable as too small.

The main material used in the construction of the container, more precisely, the material from which the container itself is made. Cover material may vary; actually, in models made of solid materials ( glass, stainless steel, ceramics, porcelain), the covers are still made of plastic or silicone, because. to perform them from the "native" material is impractical for a number of reasons.

— Plastic. The main advantage of plastic is its low cost. In addition, this material has a low weight, good strength and can sag noticeably under load; the latter allows you to slightly "squeeze" plastic containers to fit in tight spaces (if the contents allow, of course). Also note that plastic is most often made transparent, which allows you to see the contents without opening the tray; this is especially important for vacuum packed containers (see "Functions/Characteristics"). On the other hand, there are a fairly large number of different types of plastic on the market, and not all of them are suitable, for example, for long-term storage, loading hot foods or using in the microwave — these properties should be paid special attention when choosing a plastic container, because . if the conditions of use are violated, plastic can release harmful substances. Theoretically, the release of such substances can also occur upon contact with acidic foods (berries, vinegar...-based salads, etc.) — they are also not recommended to be stored in plastic containers. Also note that plastic is rather reluctant to wash off fat — sometimes you need to expend a lot of effort to completely wash the container, especially in the corners.

— Glass. The advantages of glass are, firstly, transparency, which allows you to see the contents, and secondly, general practicality. So, this material is completely chemically inert, which allows you to store absolutely any products in glass containers; it normally tolerates both low and fairly high temperatures, is compatible with microwave ovens and dishwashers. On the other hand, glass is not suitable for "camping" containers and is designed mainly for storing food at home. This is due to a number of properties. Firstly, this material is quite fragile and can break on impact. Secondly, the glass itself is quite heavy, and to give it the necessary strength, it is also made thick, which further affects the weight. Thirdly, it is very difficult to provide a tight-fitting lid on such a container, and most models open when turned over (although there are quite reliable products that are suitable even for liquids). Also note that glass is sensitive to sudden changes in temperature, which is why a heated container cannot be placed immediately under cold water — it can crack.

— Silicone. The synthetic polymer material, which looks like plastic, is also quite elastic and becomes transparent. At the same time, silicone has a number of advantages. So, it is compatible with almost any product and does not emit harmful substances, and also tolerates contact with hot contents and microwave heating well. Silicone containers most often have tight-fitting lids that are safe even when turned over. The main disadvantage of this material is its rather high cost.

— Stainless steel. This category includes two types of material — pure "stainless steel", which does not have special coatings, as well as enameled. Anyway, the most noticeable advantage of steel is its high strength — such a container will not break even from a fairly strong impact, and the elasticity of the material also prevents the appearance of dents. In addition, many containers made of this material are able to withstand fairly strong heat — up to use in the oven for baking. But steel containers are in principle incompatible with microwave ovens. In addition, they have other disadvantages. So, steel is opaque, and you can only see the contents without opening the container through the lid. And the lid itself most often does not close very tightly, and it is undesirable to turn such a container over when filled (although there are exceptions). It is also believed that non-enamelled steel containers are not well suited for long-term storage of wet food — despite the "stainless" properties, some oxidation is inevitable, which may cause the taste of the contents to deteriorate.

— Ceramics. Classic ceramic materials, similar to those used in dinner plates and other utensils. In terms of practical properties and application, they are similar to glass (in particular, they are designed mainly for permanent storage in one place), but on the one hand, usually, they are opaque, on the other hand, they are more resistant to temperature extremes. In addition, ceramics are usually decorated with drawings or ornaments, and in general, this option is designed for those who need not only practical, but also beautiful looking containers.

— Porcelain. A specific type of ceramic (see above), which has all the characteristic practical properties, but has a very pleasant appearance and is used mainly for design reasons. In general, porcelain containers look elegant, but they are also expensive.

General shape of the container(s). Please note that extensive sets (see “Type”) may include containers of different shapes; for such cases, the option that most containers correspond to is usually indicated; the remaining options are given in the notes.

The most popular shapes are classic geometric shapes - circle, oval, square, rectangle. At the same time, containers that differ slightly in the length of the sides can also be classified as squares - if this difference is not noticeable to the eye. Non-standard containers are also produced, often they have an original design - for example, a semicircle with an orange slice coloring.

The shape determines the appearance, overall ease of placement of the container and ease of cleaning. So, for example, round containers have a minimum of corners, and some are generally made in the shape of a hemisphere - which makes them easier to clean compared to square and rectangular ones. On the other hand, square and rectangular containers are most useful when storing in tight spaces, such as a busy refrigerator - they can be stacked as tightly as possible, side by side, whereas round containers will inevitably have gaps between them.

The type of products for which the container is intended.

— For food. The most common type of containers, intended mainly for solid food (in the broad sense of the word — second courses, sandwiches, etc.). Some models can be equipped with tight-fitting lids and are also suitable for liquids, but this point needs to be clarified separately. And in general, the variety of functions and materials can be quite extensive, so the compatibility of the container with specific types of food is also worth checking before buying.

— For liquids. Specialized models designed primarily for liquids. A distinctive feature of such containers are tight lids with latches that can be closed very tightly and held in place even when turned over. In addition, containers for liquids most often have a round shape and a rather large height (in other words, they look elongated upwards) — this allows you to conveniently pour the liquid by tilting the container. There are other options in shape, but they are still designed for the convenience of working with liquids. This option is useful primarily for carrying ready-made first courses — soups, noodles in broth — and other liquid products, such as vitamin cocktails.

— For the salad. Containers intended for salad may well be used with other products, however, regular use is still the most convenient and practical. "Salad" containers are usually round and often made of glass or ceramics: these materials tolerate contact w...ith vinegar, sour vegetables and other similar products, and the appearance of such a container often allows it to be used even as a salad bowl. However, relatively inexpensive models are also produced, made of plastic (see "Material").

The minimum temperature that a container can safely tolerate. Almost all modern food containers normally tolerate positive temperatures. So you should pay attention to this parameter only if the container is planned to be used for deep freezing, or used in harsh winter conditions. However, the minimum temperature in domestic freezers is rarely below -24 °C, while for food containers it is -40 °C as a standard. On the other hand, it is worth noting that many models have no mention of a minimum temperature at all; it is necessary to use such products in the cold, taking into account the materials from which they are made (see above), and if possible, refrain from doing so altogether.

The maximum temperature that the container can safely endure. Note that overheating the container can lead not only to its damage, but, in some cases, also to the release of harmful substances. Therefore, in no case should the claimed temperature be exceeded — even if the container remains intact, this does not mean that everything is fine.

The most delicate modern food containers have a maximum limit of 35 – 40 °C — this allows them to be used only for unheated food. Values of 70 °C are already found even among models compatible with microwave ovens, although for maximum guarantee it is desirable that the allowable temperature be at least 100 °C. And the most heat-resistant products (usually heat-resistant glass) can withstand temperatures up to 300 – 400 °C and can even be used for baking in the oven (although this heat resistance usually does not apply to lids, and they must be removed).
