Title: Food ingredients
1Food ingredients
- Spotlight on food additives
2Ingredient List on the food label
- Lists all of the ingredients for a food by
weight, from the most to the least. - Is a source of information for certain nutrients.
- Is a source of information for people with food
allergies.
Example
INGREDIENTS WHOLE GRAIN ROLLED OATS, SUGAR, HIGH MONOUNSATURATED CANOLA OIL, ALMOND PIECES, RAISINS, GOLDEN SYRUP, SALT, CRISP RICE (RICE FLOUR, SOY PROTEIN, SUGAR, MALT, SALT), SOY LECITHIN, NATURAL FLAVOUR
3What are food additives?
- Any substances or chemicals added to food for
specific purposes. - The Health Canada definition
- A food additive is any chemical substance that is
added to food during preparation or storage and
either becomes a part of the food or affects its
characteristics for the purpose of achieving a
particular technical effect.
4In Canada food additives do not include
- food ingredients such as salt, sugar, starch
- vitamins, minerals, amino acids
- spices, seasonings, flavouring preparations (such
as monosodium glutamate) - agricultural chemicals
- veterinary drugs or
- food packaging materials.
5- Food additives are used to keep foods safer and
to make them more appealing. - There are over 2000 different additives in common
use today. - Additives added to foods must be listed on the
food nutrition label (under ingredients).

7Types of food additives
- Anti-caking agents - stop ingredients from
becoming lumpy. - Antioxidants - prevent foods from oxidising, or
going rancid. - Artificial sweeteners - increase the sweetness.
- Emulsifiers - stop fats from clotting together.
- Food acids - maintain the right acid level.
- Colours - enhance or add colour.
- Humectants - keep foods moist.
8Regulation
- Food additives are regulated in Canada under the
Food and Drug Regulations. All permitted food
additives and their conditions of use are listed
in the tables in Division 16 of the Regulations. - The Bureau of Chemical Safety within Health
Canada coordinates the assessment of food
additive submissions.
9Are additives safe?
- Health Canada must approve all food chemicals
before they can be added to food. - Toxicological tests are done on laboratory
animals to come up with a max. daily dose with
no obervable effects. - The allowable amount for human consumption is
about 100 times less. -
10Some examples
- TARTARIC ACID, POTASSIUM ACID TARTRATE, SODIUM
POTASSIUM TARTRATE, SODIUM TARTRATE - Antioxidant used in beverages, candy, ice cream,
baked goods, yogurt, gelatin desserts, baking
powder. - Tartaric acid occurs naturally in grapes, other
fruits, and coffee beans. It has an extremely
tart, acidic taste, which is useful in some
foods. Most of the tartaric acid we ingest is
digested by bacteria in the intestines. The 20
percent that is absorbed is rapidly excreted in
the urine.
11- CALCIUM (or SODIUM) PROPIONATE
- Preservative used in bread, rolls, pies, cakes.
- Calcium propionate prevents mold growth on bread
and rolls. The calcium is a beneficial mineral
the propionate is safe. Sodium propionate is used
in pies and cakes, because calcium alters the
action of chemical leavening agents.
12- ALGINATE, PROPYLENE GLYCOL ALGINATE
- Thickening agent and foam stabilizer used in ice
cream, cheese, candy, yogurt, beer. - Alginate, an apparently safe derivative
- of seaweed (kelp), maintains the desired
- texture in dairy products, canned frosting,
- and other factory-made foods. Propylene
- glycol alginate, a chemically-modified algin,
- thickens acidic foods (soda pop, salad
- dressing) and can stabilize the foam in beer.
13- SILICON DIOXIDE
- Artificial anticaking agent Many powdered foods
like cake and pudding mixes as well as sugar and
salt. - POLYSORBATE 80
- Emulsifier ice cream most commonly since it
makes ice cream smoother and easier to handle, as
well as increasing its resistance to melting.
14- Want to know more about food additives in your
food? Visit the Food Additives Dictionary - http//www.hc-sc.gc.ca/fn-an/securit/addit/diction
/index-eng.php - If it is not in the dictionary, it is not a food
additive.
15Effects on human health
- Some food additives have been banned, others are
under suspicion but the evidence is not clear on
those. - It is up to you to assess the risks and make
decisions
16Food additives off the market
- Cyclamate an artificial sweetener that was
synthetically produced. It was banned in 1969 in
the US but is still in use in many countries
including Canada. It was - associated with bladder cancer,
- and damage to testes. Now not
- thought to cause cancer directly,
- but to increase the potency of other carcinogens.
17- Ethylene glycol was used as a solvent for food
colour and flavourings. It was banned in 1998
because of evidence of kidney damage.
18- BUTYLATED HYDROXYANISOLE (BHA)
- Antioxidant Cereals, chewing gum, potato chips,
vegetable oil. - Antioxidant
- BHA retards rancidity in fats, oils, and
oil-containing foods. While some studies indicate
it is safe, other studies demonstrate that it
causes cancer in rats, mice, and hamsters. Those
cancers are controversial because they occur in
the forestomach, an organ that humans do not
have. However, a chemical that causes cancer in
at least one organ in three different species
indicates that it might be carcinogenic in
humans. That is why the U.S. Department of Health
and Human Services considers BHA to be
"reasonably anticipated to be a human
carcinogen." Nevertheless, the Food and Drug
Administration still permits BHA to be used in
foods. This synthetic chemical can be replaced by
safer chemicals (e.g., vitamin E), safer
processes (e.g., packing foods under nitrogen
instead of air), or can simply be left out (many
brands of oily foods, such as potato chips, don't
use any antioxidant).
19- SODIUM BENZOATE, BENZOIC ACID
- Preservative Fruit juice, carbonated drinks,
pickles. - Manufacturers have used sodium benzoate (and its
close relative benzoic acid) for a century to
prevent the growth of microorganisms in acidic
foods. The substances occur naturally in many
plants and animals. They appear to be safe for
most people, though they cause hives, asthma, or
other allergic reactions in sensitive
individuals. - Another problem occurs when sodium benzoate is
used in beverages that also contain ascorbic acid
(vitamin C). The two substances, in an acidic
solution, can react together to form small
amounts of benzene, a chemical that causes
leukemia and other cancers. Though the amounts of
benzene that form are small, leading to only a
very small risk of cancer, there is no need for
consumers to experience any risk. In the early
1990s the FDA had urged companies not to use
benzoate in products that also contain ascorbic
acid, but in the 2000s companies were still using
that combination. A lawsuit filed in 2006 by
private attorneys ultimately forced Coca-Cola,
PepsiCo, and other soft-drink makers in the U.S.
to reformulate affected beverages, typically
fruit-flavored products.
20Health Claims
Disease risk reduction claims Example A
healthy diet low in saturated and trans fats may
reduce the risk of heart disease. (Naming the
food) is free of saturated and trans fats.
21Nutrition Claims
-
- Are regulated statements made when a food meets
certain criteria. - They are optional, and may be found only on some
food products.
22Nutrition ClaimsWhen you want to decrease the
amount of certain nutrients, look for
Free none or hardly any of this nutrient an example is sodium free
Low a small amount an example is low fat
Reduced at least 25 less of the nutrient compared with a similar product an example is reduced in Calories
Light can be used on foods that are reduced in fat or reduced in Calories
23Nutrition Claims When you want to increase the
amount of certain nutrients, look for
Source contains a significant amount of the nutrient an example is source of fibre
High or good source contains a high amount of the nutrient an example is high in vitamin C
Very high or excellent source contains a very high amount of the nutrient an example is excellent source of calcium
24General Health Claims
- General health claims are generally developed
- Consumers should not solely rely on general
health claims to make informed food choices.
