Food Additive atau Bahan
Tambahan Pangan
Definisi FDA:
Zat yang secara sengaja ditambahkan ke
dalam makanan untuk menghasilkan sifat
fungsional tertentu pada makanan baik secara
langsung atau tidak langsung dan menjadi
bagian dari makanan tersebut (termasuk zat
yang digunakan selama produksi,
pengemasan, pengolahan, transportasi,
penyimpanan).
What is a Food Additive?
Sec. 201(s) FFDCA: Definition
IN SHORT


Any substance, that is reasonably expected to
become a component of food as a result of its
intended use,
If such use in not Generally Recognized As Safe
(GRAS)

NATURAL vs SYNTHETIC CHEMICALS




Are natural chemicals safer than synthetic
chemicals?
Which set pose a greater risk?
Which set is more amenable to control and
regulation?
Fundamental concept of toxicology: all
substances can be toxic; it is a matter of DOSE .



Safety is relative and there is no absolute
safety.
Thus there are toxic and non toxic doses
for any substance.
Frequency-response curve: a plot of the
% of individual with specific response as a
function of dose.
Cumulative response-curve
(compounds A and B)
Dose-response curve

TOXICOLOGICAL TERMS
Toxin /Toxicant:
A substance that has been shown to present
some significant degree of possible risk when
consumed in sufficient quantity by humans or
animals.
Natural/Inherent:
Toxicants occur in foods as a result of
biosynthetic origin.

Acute Toxicity

Chronic Toxicity

Sub-chronic feeding test

Maximum tolerated dose (MTD)

No observable adverse effect level (NOAEL)

Acceptable daily intake (ADI)

Lethal dose fifty (LD50)

Tumor dose fifty (TD50)

GRAS


Acute toxicity: toxic response ,often
immediate, induced by single exposure.
The acute toxicity of a substance is
defined by its LD50 / lethal dose that will
kill 50% of a group of exposed animals .

LD50 is also used to
determine the level
of toxicity
LD50 (/Kg

LD50
Toxicity Level
≤ 1mg
Extremely Toxic
1-50mg
Highly toxic
50-500mg
>500mg
Moderately toxic
Non Toxic


Chronic toxicity:
Toxic effect that requires some time to
develop, e.g. cancer.
Testing for chronic toxicity involve
continuous feeding of the test substance
to rodents for 20-24 months.

By analogy to LD50, the amount of a
carcinogen required to induce cancer in
50% of a group of exposed animal is
referred to as TD50
Toxicology and Risk
Analysis


Traditional high dose feeding of a few
rats/other rodents.
A safety margin of a 100-fold is usually
applied from the NOAEL (no observable
adverse effect level) to determine safe
dose for man, i.e. the ADI (acceptable
daily intake).
Food Shall be Deemed to be
Adulterated

If it bears or contains any poisonous or
deleterious substance which may render it
injurious to health, but if not an added
substance it will not be adulterated if the
quantity of substance does not ordinarily
render it injurious to health.
Food Shall be Deemed to be
Adulterated

If it bears or contains
any added poisonous or deleterious substance
that is unsafe within the meaning of section
406 FDCA (tolerances for poisonous
ingredients).
 Pesticide residue.
 Unsafe food additive or unsafe new animal
drug.

Food Shall be Deemed to be
Adulterated



Consists in whole or part of any
filthy, putrid, or decomposed
substances, or if it is otherwise unfit
for food.
Prepared, packed or held under
unsanitary conditions.
Others.
Generally Recognized as
Safe (GRAS)

Any substance that is intentionally added to food is a
food additive and is subject to premarket review and
approval by FDA, unless the substance is generally
recognized, among qualified experts, as having been
adequately shown to be safe under the conditions of its
intended use, or unless the use of the substance is
otherwise excluded from the definition of a food
additive.
Food Additive Petition





Chemical composition, substances used in preparation,
etc.
Amount & proposed.
Data that it will have intended effect.
Methods to determine amount of additive in food.
Safety reports.
Food Additive-Safety
Standard

General two-part food additives standard:
Legislative history- whether substance is
hazardous to the health of man or animal.
 Must be “reasonable certainty” that no harm
will result.

The Delaney Clause

Another FDA standard is called the
Delaney cause
This states that any food additive that is shown to
cause cancer in humans or animals may not be
added to food
 GRAS List = substances, such as spices, natural
seasoning, and flavorings, that are considered safe
for human consumption and not regulated as
additives.


The GRAS list currently numbers about 670 items
The Delaney Clause _ Cont.
The Food Additives Amendment –
Delaney Clause:

Asserts that “no additive shall be deemed
to be safe if it is found to induce cancer
when ingested by man or animal, or if it is
found after tests which are appropriate for
the evaluation of the safety of food
additives, to induce cancer in man or
animal …”
Food Additives
Toxicity Testing

NOEL: No-Observed-Effect Level

Highest exposure that does not produce an
adverse effect.
Safety Factor

Safety Factor: used to account for
differences between humans and animals.

Generally, a safety factor of 100 is used to
apply animal test data to man.

May be modified based on subpopulation (e.g.
children where it might be increased).
Apakah Bahan Tambahan Pangan?
Definisi PerMenkes No.722/Menkes/Per/IX/88:
Bahan yang biasanya tidak digunakan sebagai
makanan dan biasanya bukan merupakan ingredien
khas makanan, mempunyai atau tidak mempunyai nilai
gizi, yang dengan sengaja ditambahkan ke dalam
makanan untuk maksud teknologi pada pembuatan,
pengolahan, penyiapan, perlakuan, pengepakan,
pengemasan, penyimpanan atau pengangkutan
makanan untuk menghasilkan suatu komponen atau
mempengaruhi sifat khas makanan tersebut.

How Additives Are Used

The purpose of additives fall into four
categories
1.
2.
3.
4.
5.
Improve storage properties
Increase healthfulness
Make food more appealing
Improve processing and preparation
Cost-benefit
Improving Processing and
Preparation

Stabilizer, substance that keeps a
compound, mixture, or solution from
changing its form or chemical nature.

Example without stabilizer, the fat in peanut butter
separates from the protein, creating an oil pool
over a stiff paste.

Ice cream is creamy, in part because thickeners prevent
crystals from forming as it freezes and stabilizes.
 Many stabilizers are natural and starch-based.
 Some are made from pectin, casein, sodium
caseinate, and gelatin.
Increasing Healthfulness

Increasing additives is also included in boosting a food’s
nutritional profile.
 Fortification = is adding nutrients that are not normally



found in a food (ex. Milk is fortified with vit. D)
Restoration = nutrients that are lost in processing are
returned to the food with the process called restoration
(reestablishes the product’s original nutritive value ex. Vit.
C is put back into canned oranges)
Enrichment = adding nutrients lost in processing
(contain more nutrients than existed in the food before
processing (ex. Vitamins are increased)
Nitrification = process that adds nutrients to a food with
a low nutrient/kcalorie ratio so the food can replace a
nutritionally balanced meal (nutrition bars and shakes are
examples)
Concerns About Food Additives

Some people believe that some additives
cause “more trouble than they’re worth.”

One concern is not enough is known about
the long-term effects

Example is nitrites which react with amines
(preservative in meat) is suspected of causing
cancer


Nitrites prevent botulism, which the FDA believe will out
way the risks of using them, however the FDA required
them to be used in lower quantities.
DO YOU THINK THERE ARE ANY RISKS IN EATING SO
MANY PROCESSED FOODS?
The Value of Food Additives

Preservatives extend the shelf life of many
foods


Ex. mold inhibitor calcium propionate and BHT are
used in bread to prevent mold (keeping the fat
fresh)
Supporters of food additives say additives
prevent disease caused by malnutrition

Goiter = an enlargement of the thyroid glad
caused by a lack of iodine


This was then added to table salt in 1924
Vit. D was added to milk in the 1930’s to help with
rickets (bone-deforming disease)
Mengapa Produsen Pangan Perlu
Mengetahui BTP?

Penyimpangan atau pelanggaran mengenai
penggunaan BTP yang sering dilakukan oleh
produsen pangan, yaitu:


Menggunakan bahan tambahan yang dilarang
penggunaannya untuk pangan

Menggunakan BTP melebihi dosis yang diizinkan

Adulteration
Produsen pangan perlu mengetahui mengenai sifatsifat dan keamanan penggunaan BTP, serta
mengetahui peraturan-peraturan yang telah
dikeluarkan oleh pemerintah mengenai penggunaan
BTP.
Mengapa Konsumen Pangan Perlu
Mengetahui BTP?

BTP umum digunakan/ditemui oleh masyarakat,
termasuk dalam pangan jajanan.

Pelanggaran penggunaan BTP oleh produsen:

The “Hopi Red Dye” was originally used by the Native
American tribe , the Hopi for a deep red dye

Today we know it better as FD&C Red No. 2

Uses

The “Red Scare”
Amaranth

A study was conducted to determine the
possible carcinogenic effects of the color
additive Amaranth
Done with mice
 Mice were given a dose of 200 or 1000 mg/kg
body weight
 Examined the mice gut and feces after given the
dose of amaranth

Study Results
Is Amaranth Safe?

Study Conclusions…


Supported amaranth as a safe additive
Amaranth is considered a non
mutagenic substance
Amaranth


Amaranth is still used in Canada and Europe today.
Despite research studies that support Amaranth as a
safe additive the FDA banned its use in the United
States based on the concept that the additive could
possibly not be safe!
Tartrazine

Outcome of the re-evaluation of colours:
Example of Azo dyes
Azo dyes recently re-evaluated by EFSA
Tartrazine (E102)
 Azorubine/Carmoisine (E122)
 Allura Red AC (E129)
Conclusions:
1. The Panel concluded that there was no need to change the previously
established Acceptable Daily Intakes (ADIs)
2. Some children who consume large amounts of food and drink containing
Azorubine/Carmoisine or Allura Red AC could exceed the ADIs for these colours

Quinoline Yellow (E104)
 Sunset Yellow FCF (E110)
 Ponceau 4R (E124)
Conclusions:
1. The ANS Panel has lowered the ADIs (e.g. from 4 mg to 0.7 mg/kg bw/day for
Ponceau 4R)
2. The Panel concluded that exposure to these colours could exceed the new ADIs
for both adults and children

What Does the Research
Say?

There is research available that support
certain additives as a carcinogenic agent
and there are also studies that show some
additives are completely safe and could
also have anti-cancer affects.
