FOOD INTOLERANCE NETWORK FACTSHEET

Safe food additives

This Factsheet is to assist food manufacturers to choose safe food additives they CAN use, rather than just those to avoid. It is encouraging that such questions are now being asked by responsible manufacturers.

Of about 1500 food additives approved for use under the Australian Food Standards Code, which mirrors international standards, only about 50 are known to cause problems according to Royal Prince Alfred Hospital research. The majority of food additives, while they may or may not be necessary, are not known to be harmful. This majority includes anti-caking agents, bleaches, emulsifiers, mineral salts, propellants, food acids, sweeteners, thickening agents, vegetable gums and vitamins.

The good news is that there are alternative safe additives that can be used to substitute for nearly all the harmful additives without loss of technological function.

There are new additives (in italics) emerging all the time. No additives are tested for health, behaviour and learning effects by FSANZ, so it may take some time for the Food Intolerance Network to encounter, identify and report new problems. Always check for the latest. Last update November 2006.

PRESERVATIVES
AVOID		ALTERNATIVES
Sorbates	Calcium sorbate 203 Potassium sorbate 202 Sodium sorbate 201 Sorbic acid 200	USED IN processed fruit and vegetable products, drinks, wine. SAFE ALTERNATIVES to many preservatives include refrigeration, freezing, ascorbates 300-304.
Benzoates	Benzoic acid 210 Calcium benzoate 213 Potassium benzoate 212 Sodium benzoate 211	USED IN most soft drinks, diet drinks, cordials, juice drinks. SAFE ALTERNATIVES How is it that 7UP, some Schweppes products and non-diet Coca-Cola don't need this preservative? Ascorbates 300-304 can be used.
Sulphites (sulfites)	Calcium hydrogen sulphite 227* Calcium sulphite 226* Potassium bisulphite 228 Potassium metabisulphite 224 Potassium sulphite 225 Sodium bisulphite 222 Sodium metabisulphite 223 Sodium sulphite 221 Sulphur dioxide 220	USED IN wine, beer, bread, processed meat like sausages, seafood like prawns, dried fruit, prepared salads, fruit salads, fruit and vegetable products, like drinks. SAFE ALTERNATIVES Include ascorbates 300-304 in some applications. Calcium sulphate 516 and ascorbic acid 300 are safe alternatives to sodium metabisulphite used as a flour improver. For sausages, freezing is a safe alternative.
Nitrates & nitrites	Potassium nitrate 252 Potassium nitrite 249 Sodium nitrate 251 Sodium nitrite 250	USED IN processed meats like ham, salami, devon. SAFE ALTERNATIVES Salt.
Propionates	Calcium propionate 282 Potassium propionate 283 Propionic acid 280 Sodium propionate 281	USED IN most bread in Australia and USA. Recently permitted in cheese, fruit and vegetable products. Very rare in Europe. Also added as fermented whey powder. SAFE ALTERNATIVES In bread, a safe alternative is better bakery hygiene, such as wiping surfaces and machinery with vinegar, or cooling loaves before placing in plastic bags. Ascorbates 300-304 can be used in some other applications.
Antioxidants	Butylated hydoxyanisole (BHA) 320 Butylated hydroxytoluene (BHT) 321 Dodecyl gallate 312 Erythorbic acid 317 Octyl gallate 311 Propyl gallate 310 Sodium erythorbate 318 tert-Butylhydroquinone 319	USED IN oils and margarines to prevent rancidity, chips, fried snack foods, fast foods. Not necessarily listed on labels where vegetable oil is a component, due to the 5% labelling loophole. SAFE ALTERNATIVES Ascorbates 300-304, Tocopherols 306-309.
FLAVOUR ENHANCERS AND ADDED FLAVOURS
AVOID		ALTERNATIVES
Glutamates	Calcium dihydrogen diLglutamate 623 Disodium guanylate 627 Disodium inosinate 631 L-Glutamic acid 620 Magnesium di-L-glutamate 625 Monoammonium L-glutamate 624 Monopotassium glutamate 622 Monosodium glutamate (MSG) 621 Sodium 5' ribonucleotide 635	USED IN tasty foods like flavoured noodles, snack foods, chips, crackers, sauces and fast foods. Glutamates are in hydrolysed vegetable protein (HVP), 'plant protein', yeast extract, caseinate, broth, stock and 'natural flavourings'. 635 is now even to be found in butter! SAFE ALTERNATIVES salt. Glutamates were introduced into Western food after WWII and is now used at levels far higher than ever used in the East. Do we need hyper-tasty food?
Added flavours	Many.	USED IN many foods without regulation. SAFE ALTERNATIVES some natural flavours including vanilla.
