4. Introduction
Canning of food and beverages allows their
preservation for months to years while
maintaining taste and nutritional values.
Metal cans are generally coated with an
organic layer protecting the integrity of
food cans from effects of the food.
o This overview explores the use of
BPA in cans coating and its risks
and other safe alternatives of BPA
,

( B P A ) ?
Bisphenol A (BPA) is an industrial chemical
compound primarily used in the manufacturing of
plastics, such as plastic bottles and food containers.
It is also used in the internal coatings of cans to
prevent corrosion. BPA is found in certain
polycarbonate products, including sunglasses, CDs,
DVDs, and numerous household plastic items.
6. Canned foods include a large
variety of vegetables, fruits,
meat, and fish, but also dairy
products and ready meals.

7. A large variety of can coatings are
commercially available. However, only
a limited number of chemical
functionalities is used to produce
these resins.
• The main types of resins are
Eboxy
Oleoresin
Vinyl
Phenolic
Acrylic
Polyester
Polyolefins

8. Since the 1950s, epoxy-based resins
became the most commonly used class
of coatings for aluminum and steel cans.
E p o x y
The most common epoxy coatings are
synthesized from bisphenol A(1) and
epichlorohydrin (2) , forming bisphenol A-
diglycidyl ether epoxy resins (3)
Epoxy coatings protect the metal
from corrosion, withstand a wide
range of foods and resist heat and
acidic conditions.
9. Since the late 1990s, numerous studies from all over the world
demonstrated that the occurrence of BPA in epoxy can coatings and
its migration from such coatings into food and beverages are
common phenomena.

Migration of BPA mainly occurred during can processing, sealing
and sterilization, and less during storage or after can damage.

•risks related to the reproductive system
Bisphenol A poses potential risks to adult health, including
•heart health
•metabolic health
•hormonal health
•liver health
and overall systemic health.
11. Alternatives to
epoxy coatings
Several alternatives to epoxy coatings can be used
to reduce exposure of BPA in products, such as
•Acrylic and polyester coatings
•polyolefin and non-BPA epoxy coatings
•BPA-free polycarbonate
• non-plastic materials (glass, ceramic, stainless
steel, cardboard)
•and BPA-free epoxy coatings.
It is essential to note that each alternative may
have its own advantages and disadvantages.
12. C onclusions
In conclusion, exposure to bisphenol A is a
major concern in the field of food science.
Numerous studies underscore the potential
health risks associated with this chemical
present in food packaging. It is imperative to
continue research and implement strategies to
minimize consumer exposure to bisphenol A,
while raising awareness about safer alternatives
to ensure long-term food safety.
