Food concentrates

Food concentrates - dry sets food, prepared for use after a short heat treatment. Food concentrates are made from high quality raw materials and contain all the necessary ingredients to provide nutritious and flavouring properties produced dishes according to their layout, high nutritional value. The range of food concentrates includes a variety of first, second and third dishes, dietary cuisine, dairy and cereal mixtures for baby food and other the following table shows the chemical composition and caloric content of some food concentrates.
Food concentrates can be in the form of briquettes, sealed in bags, banks, etc. that are normally specified the composition of food concentrates, expiry dates and method of preparation. Due to low water content of food concentrates resistant storage; so, soups beans can be stored for up to 12 months, cereals and cereals (10% fat) - up to 6 months. Most often the damage is exposed to fat, which are oxidized, worsen the taste indicators of food concentrates. Manufacture of food concentrates without fat or low fat helps to extend their shelf life. During the implementation of food concentrates need to control the terms of their storage, and in case of exceeding these terms to allow the sale only after the respective analysis.
Food concentrates are widely used in the expeditions, tourist trips and other conditions, where cooking is difficult.

Table for conversion concentrations
Note: d-density of a solution, MoE, and e-molecular and equivalent weight of dissolved substances respectively. For the calculation of the concentration of the solution, expressed in %0 or mg %, in percentage concentration first need to divide by 10, and the second one in 1,000.
The concentration of the solution is the amount of dissolved substances contained in a given volume of solution or solvent. The table lists the most commonly used in biomedical laboratories ways of expressing concentrations.
Percentage concentration weight (weight %, and %) specifies the amount of weight parts of the dissolved substance contained in 100 weight parts of a solution. If, for example, the concentration of aqueous solution of glucose equal to 8%, in 100 g solution contains 8 grams of glucose and 92 g of water. The concentration of very dilute solutions often Express the number of milligrams of dissolved substances contained in 100 grams of the solution, or if it is an aqueous solution, 100 ml of water (water density close to one), i.e. in milligrams-per cent (mg%). Concentration in parts per thousand (PPT) expresses the number of parts by weight of dissolved substances in weight 1000 pieces of the solution. Interest volumetric concentration (volume %V %) specifies the number of volumes of the solute is contained in 100 volumes of the solution. Volume% usually Express the composition of gas mixtures or solutions of gases and liquids in liquids.
Molar concentration (both molarity of a solution, M) shows the number of moles, i.e. gram-molecules (see Molecular weight)contained in 1 l of a solution. If in 1 litre of solution contains 1 mol of the dissolved substance, solution called odnomestniy (1 M), 0,1 mol - decimomannu (0.1 M), 0,01 mol - antimalarial (0.01 M), etc.
Normal concentration (normality of a solution, N.) specifies the number of gram-equivalents (see Equivalent weight) dissolved substances contained in 1 l of a solution. If in 1 litre of solution contains 1 g-EQ dissolved substance, solution called odnokryly (1 N.), 0.1 g-EQ - decimomannu (0.1 N.), 0.01 g-EQ-antinormal (0,01 N.), etc.
The title of the solution (T) shows, how many grams of dissolved substances contained in 1 ml of solution. If, for example, the title of hydrochloric acid equal 0,0036, in 1 ml of solution contains 0,0036 g Hcl.
