Trace by: Number/Name/Comments

• 200/E200; Sorbic acid; Occurs naturally in fruit, used as a preservative it inhibits fungal growth but allows for bacterial activity, hence is useful for cheese. Obtained from the berries of mountain ash or synthesised from ketene; possible skin irritant, and may cause rashes, asthma and hyperactivity.. Sorbic acid is used in conjunction with sulphur dioxide in wine making, without SO2 bacteria cause reduction of sorbic acid to sorbyl alcohol which converts to a foul smelling ether. Also used as a preservative in cosmetics and pharmaceuticals. Sorbic acid had a conjugated system of double bonds which makes it susceptible to nucleophilic attack, sometimes giving mutagenic products.

Banned in Australia.
• E240; Formaldehyde; Formaldehyde is the most important industrial aldehyde with about 3.6 million tonnes of formaldehyde being made each year. The industrial synthesis of formaldehyde involves methanol. The incomplete combustion of organic compounds results in formaldehyde formation, hence smoked foods are preserved not only by phenolic substances present in the smoke, by the formaldehyde coating. It is also used as a disinfectant and a fungicide. Its main application is in the preparation of phenolic resins (or phenol-formaldehyde copolymers, e.g. bakelite). Formaldehyde is also used in the preparation of ribose. Other names: formalin, formic aldehyde, methylene oxide, oxomethane, paraform.Other Info: Causes burns.

Excessive ingestion may result in such high concentrations of nitrites in the bloodstream that reduced concentrations of oxygen are carried by haemoglobin in red blood cells, resulting in shortness of breath, dizziness and headaches. Nitrites may also form nitrosamines in the stomach, thought to be carcinogenic agents. Potassium nitrite inhibits the growth of bacteria responsible for botulism, retards development of rancidity, and preserves flavours. Less than 10% of nitrate (nitrite) intake is from cured meats, with the rest coming from mainly root vegetables.

It is used as a preservative and curing agent in meat. See E249, potassium nitrite. Typical products include processed meats, cured and smoked meat and fish, root vegetables. Also used in the manufacture of nitric acid, as a fertiliser. (see 250). Harmful if swallowed or inhaled. Skin, eye and respiratory irritant. Other names: Chile saltpetre, cubic nitre, nitric acid sodium salt
• 252/E252; Potassium nitrate; Potassium nitrate is a naturally occurring mineral used as a preservative and curing agent in meat. It is artificially manufactured by the reaction of potassium chloride with nitric acid. See E249, potassium nitrite. Potassium nitrate is used in fireworks as well as fertilisers.

If during the fermentation of grapes or other fruits, oxygen is allowed into the container, then bacteria convert the ethanol present into ethanoic acid causing the wine to turn sour. Acetic acid may be synthetically produced using methanol carbonylation, acetaldehyde oxidation, or butane/naphtha oxidation. Pure acetic acid is termed "glacial", and is completely miscible with water. Typical products include fish fingers, butter, margarine, processed cheese, curry powder, cooking oil.

Technical grade sodium acetate is used as a mordant in dyeing processes, as buffers in petroleum production, and for kidney dialysis processes. In plastic manufacturing it is used as a retarder for some elastomers. Typical products include bouillons. No known adverse effects. May irritate the skin, harmful if ingested.(ii) Sodium hydrogen acetate (sodium diacetate) - A vinegar used as a mould inhibitor in snack foods and bread, as a flavour enhancer in breads, cakes, cheese and snack food. Technical grade sodium hydrogen acetate is used as a buffer in petroleum production. Typical products include bread, crisps and other snack foods, cheese, cakes.
• 263/E263; Calcium acetate; Calcium acetate is used in food as a thickening agent (cake mixtures, puddings, pie fillings), as a buffer in controlling the pH of food during processing, as a preservative to prevent microbial growth, and as a calcium supplement in pet products.

D- or DL-lactates (stereoisomers) should not be given to babies and small children, as they have not yet developed the appropriate enzymes in the liver to metabolise these forms of lactate; used in sweets, dressings, soft drinks (sometimes beer), infant formulas and confectionary. lactic acid and lactates can be consumed by all religious groups, vegans and vegetarians. Although the name refers to milk, it is mot made from milk and thus suitable for people with milk allergy or lactose intolerance.
• 280/E280; Propionic acid; All propionates are thought to be linked with migraine headaches; propionates occur naturally in fermented foods, human perspiration and ruminants digestive tract, also can be derived commercially from ethylene and carbon monoxide or propionaldehyde or natural gas or fermented wood pulp; produced when bacteria decompose fibre; commonly used in bread cheese and flour products. Corrosive - causes burns. Harmful if swallowed. Liquid may burn eyes. Severe eye and skin irritant. Other names: carboxyethane, ethylformic acid, methylacetic acid.
• 281/E281; Sodium propionate; Sodium propionate is the sodium salt of propionic acid, E280. It is used as an antimicrobial agent in bread to prevent germination of some types of bacteria which causes sticky yellow patches to occur. Occurs naturally in fermented food, human sweat and stomachs of cows. May irritate the eyes and skin, readily absorbed through the skin. May be linked to migraines, typical products are processed cheese and flour/bread products. Other names: propionic acid, sodium salt.
• 282/E282; Calcium propionate; Calcium propionate is the calcium salt of propionic acid, E280.

It is used as an antimicrobial agent in bread to prevent germination of some types of bacteria which causes sticky yellow patches to occur. Typical products include bakery products, dairy products. See 281.
• E284; Boric acid; Preservative and bleaching agent. Boric acid is best known for being an antiseptic, but it is also used in insecticides, leather finishing, paints, soaps, wood preserving, and in ceramics and glass manufacturing. Boric acid is industrially synthesised by treating borax with strong acid. Boric acid forms crystals in which a planar array of BO3 units is joined by unsymmetrical H bonds. Used in foods, cosmetics, pharmaceuticals and numerous industrial processes. Used in Australia for a well known ant poison. Suspected to be a neurotoxic hazard. Ingestion is harmful and may be fatal. Harmful by inhalation. Irritant. May cause congenital malformation in the fetus. Laboratory tests with animals suggest this material may cause reproductive disorders.
• E285; Sodium tetraborate (borax); Borax has many industrial uses including as an added ingredient in washing powders, water softeners and soaps. Borax is also mixed with clay and other substances to produce porcelain enamels which is used in pottery, sinks etc. It is also used in the glass industry, the textile industry, in tanning leather, and in the manufacture of paper. Borax is obtained by mining of boron-containing rocks, or by recrystallisation from water sources. A major source of borax is the mineral kernite, abundant in the Mojave Desert. Other names: borax decahydrate, boricin, disodium tetraborate decahydrate. Possible risk that this may cause reproductive disorders, based on tests with laboratory animals. Eye and skin irritant. Harmful by ingestion. May be harmful by inhalation.
• 290/E290; Carbon dioxide; Propellant, coolant, derived from lime manufacture; may increase the effect of alcohol; typical products are wine, soft drinks, confectionary. Delays ripening of fruit and vegetables. Suspected of being a neurotoxic hazard. More than 10% in the air causes blackouts.
