The use of aluminum in the food industry
Modern food industry is impossible without aluminum. But not all products are regulated by GOST. The questions arise when you need to oblitsevat inside a container or box for food, to produce a form for the baking tray to unjam the counter. What kind of aluminum can be called food? For products made of aluminum or aluminum alloys — just open the GOST.
GOST 1583−93. 3.3
For food purposes used alloy AK7, AK5M2, AK9, AK12. The use of other alloys for products and equipment in contact with food products and environments should be, in each case, permitted by the health authorities. In aluminum alloys for products, edible fraction of lead should not exceed 0.15%, arsenic of 0.015%, zinc 0,3%, beryllium — 0, 05%.
GOST 1583−93. p.
Ingots for manufacturing of products and equipment in contact with food products shall be labelled in the absence of a color marking additional letter «P» after the designation of the grade alloy.
GOST 17 151−81. p. 2.3.
Reglementary the manufacture of household utensils of sheet aluminium Cookware should be made of sheets and strips of aluminum AD1 brands, the HELL with the chemical composition according to GOST 4784, aluminum grades A7. A6. A5 and A0 with the chemical composition according to GOST 11 069 and bimetallic strips of aluminum AD1 brands, AD (chem. the composition is regulated by GOST 4784) and steel strip grades and 12X18H10T 08X18H10T chemical composition is regulated by GOST 5632. If the utensils inner coating allowed to take her out of the sheets and strips of aluminium alloy brand AMC (chem. the composition corresponds to GOST 4784). Fasteners having contact with food products should be made of the same materials as the dishes. The chemical composition of the fittings (handles, handles, lugs, etc.) of aluminum must comply with GOST 11 069 and aluminum alloys GOST 4784.
GOST 51 016−97
Reglamentary General technical conditions of the production of Cutlery made of carbon steel and aluminum alloys. From casting aluminum alloy AK7, AK5M2, АЛ22 (Amg11), АЛ23 (Amg6l) produce fragile aluminum canteens device, and sheet aluminum brands АД1М, AD1 A0, AVM, AB, and Amg2 — soft.
Cutlery should be made of materials listed in table 2.

|Note — with the permission of the health authorities may use other alloys similar to those described in table 2|
Food contact aluminum primary grades, or aluminum deformable technical grades AD-AD0 (not to be confused with the alloys Al-Mg-Si AD31, AD33, AD35, although of alloy grade AB also produce forks and spoons). GOST permits apply for the production of forks and spoons of magnesium alloys in sheets and ingots Amg2 АЛ22 (Amg6l), АЛ23 (Amg11), and alloy Al-Mg-Si AB. GOST 4784 «Aluminum and aluminum deformable alloys. Stamps» complements the list of permitted food alloys the following clarification.
GOST 4784, p. 3.8
In aluminum alloys, which are intended for the manufacture of products food products, the proportion of lead should not exceed 0.15%, and the proportion of arsenic — 0.015% FS However GOST 4784 does not specify the allowable percentage of beryllium and zinc, as GOST 1583 for cast alloys, it is Logical that in wrought alloys should not be lead and beryllium more permissible concentrations, except AMg5, AMg6, D19, where beryllium — 0, 02% to 0, 5% (GOST 1583 admits to 0.05%,) and also some brands of welding wire: Svamg5, Sv1557, Svamg6, Svamg61, Svamg63 where beryllium — from 0.2% to 0.5%.
SNIP in Ukraine
In Ukraine there Are Sanitary norms and rules 42−123−4240−86. «Allowed number of migration (DCM) of chemical substances emitted from polymer and other materials in contact with food products and methods of their definition». The document is the norm DCM metals, polymers allocated, but no rules DKM for metal products.
In the Russian Hygienic standards — «Maximum allowable quantities of chemical substances emitted from materials contacting with food products» has a valid sanitary norms and the hazard class of the use of aluminium and its alloys:

The main document is approved by the Ministry of health of the USSR from 7.VIII.79 № 123−12.328−7 with additions RTM 27−72−15−82 «the Order of application of metals and other synthetic materials contacting with food products and environments». To the permission of the USSR Ministry of health materials for finishes refer still SNIP (sanitary norms and rules) for the food industry. The rules provide a health certificate on the application of a particular alloy when the alloy corresponds to the RTM 27−72−15−82. What to do if you need to oblitsevat counter or Boxing? It is best to take the sheets of aluminum brands, or HELL, allowed the guests for making pots or apply for a certificate in sanepidkontrol.
