Aluminum applications in the food industry
Relevance
The modern food industry is impossible to imagine without aluminum. But not all products are regulated by GOST. Questions arise when you need to clad the inside of a container or box for food, make a mold for muffins, tray, to outline the counter. What kind of aluminum can be called food-grade aluminum? For products made of aluminum or aluminum alloys - just open GOST.
GOST 1583-93. П. 3.3
Alloys AK7, AK5M2, AK9, AK12 are used for food products. Use of other alloys for products and equipment in contact with food products and environments must be permitted by health authorities in every particular case. In aluminum alloys for food products the proportion of lead must not exceed 0,15%, arsenic - 0,015%, zinc - 0,3%, beryllium - 0, 05%.
GOST 1583-93 item 4.1.6.1
Stocks for the manufacture of products and equipment in contact with food, are marked in the absence of color markings with an additional letter "P" after the designation of the alloy grade.
GOST 17 151-81. item 2.3.
It regulates the production of household utensils from aluminum sheets Dishes shall be made of sheets and strips of aluminum of AD1 and AD grades with the chemical composition according to
GOST 51 016-97
It regulates the general technical conditions for production of cutlery made of carbon steel and aluminum alloys. Cast aluminum alloys AK7, AK5M2, AL22 (AMg11), AL23 (AMg6l) are used for making fragile aluminum cutlery, and soft aluminum cutlery is made of cast aluminum grades AD1M, AD1 A0, ABM, AB, and AMg2.
П. 4.3.1
Cutlery shall be made of the materials specified in Table 2.

Cutlery
It is allowed to contact with foodstuffs with primary aluminum of А, А, or technical aluminum wrought of АД-AD0 grades (not to be confused with Al-Mg-Si alloys АД31, АД33, АД35, though forks and spoons are also produced from АB grade alloy). GOST permits the use of magnesium alloys in sheets of AMg2 and in ingots of AL22 (AMg6l), AL23 (AMg11), as well as Al-Mg-Si alloy of AB for the production of forks and spoons.
GOST 4784, clause 3.8
In aluminium alloys, which are intended for production of articles for food purposes, the share of lead must not exceed 0.15% and the share of arsenic 0.015%. However,
SNIP in Ukraine
Sanitary norms and rules 42-123-4240-86 are in force in Ukraine. "Permissible migration quantities (PMQ) of chemical substances emitted from polymeric and other materials in contact with foodstuffs and methods of their determination". The document has standards of DKM of metals emitted by polymers, but there is no standard DKM for metal products.
GN 2.3.3.972.
Russian Hygienic Norms - "Maximum allowable quantities of chemical substances emitted by materials coming into contact with foodstuffs" has allowable sanitary norms and class of hazard of aluminum and its alloys:

Certification
The basic document is still approved by 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, synthetic and other materials in contact with food products and media. The finishing materials approved by the Ministry of Health of the USSR are still referred to SNIP (sanitary norms and rules) for food enterprises. The rules provide for a hygienic certificate for the use of a particular alloy, if the alloy complies with RTM 27-72-15-82. What to do if you need to clad a counter or box? It is best to take sheets of aluminum grades, A or AD, approved by GOST for the manufacture of pots, or ask for a certificate in sanitary-epidemiological control.
