A preservative is a naturally occurring or synthetic substance that is added to products such as foods, pharmaceuticals, paints, biological samples, wood, etc. to prevent decomposition by microbial growth or by undesirable chemical changes.

Preservatives may be antimicrobial preservatives, which inhibit the growth of bacteria or fungi, including mold, or antioxidants such as oxygen absorbers, which inhibit the oxidation of food constituents.

Natural substances such as salt, sugar, vinegar, alcohol, and diatomaceous earth are also used as traditional preservatives.

processes such as freezing, pickling, smoking and salting can also be used to preserve food.

Some modern synthetic preservatives have become controversial because they have been shown to cause respiratory or other health problems.

Food preservation is the process of treating and handling food to stop or greatly slow down spoilage .

Maintaining or creating nutritional value, texture and flavour is important in preserving its value as food.

Preservation usually involves preventing the growth of bacteria, fungi, and other micro-organisms, as well as retarding the oxidation of fats which cause rancidity.

Common methods of applying these processes include drying, spray drying, freeze drying, freezing, vacuum-packing, canning, preserving in syrup, sugar crystallisation, food irradiation, and adding preservatives or inert gases such as carbon dioxide.

i. Preservation processes include:ii. Heating to kill or denature micro-organisms (e.g.

boiling)iii. Oxidation (e.g. use of sulfur dioxide)iv. Toxic inhibition (e.g. smoking, use of carbon dioxide,

vinegar, alcohol etc.)v. Dehydration (drying)vi. Osmotic inhibition (e.g. use of syrups)vii. Low temperature inactivation (e.g. freezing)viii. Ultra high water pressure (e.g. fresherized, a kind of

“cold” pasteurization, the pressure kills naturally occurring pathogens, which cause food deterioration and affect food safety.)

Jacob's is a brand name for several lines of biscuits and crackers. The brand name in the United Kingdom is owned by United Biscuits while the brand name in Ireland is owned by the Jacob Fruitfield Food Group.

The originator of the Jacob's brand name was the small biscuit bakery, W & R Jacob, founded 1881 in Waterford, Ireland. It later moved to Bishop Street in Dublin, Ireland, and also opened a branch in Liverpool, England.

In the 1920s the two branches separated, with the Dublin branch retaining the W & R Jacob name while the Liverpool branch was renamed Jacob's Bakery Ltd. In the 1970s, W & R Jacob in Dublin merged with Boland's Biscuits to form Irish Biscuits Ltd. and moved to Tallaght, Ireland.

In 1990, the two companies once again came under common ownership and became Jacob's Biscuit Group when they were acquired by the French company Groupe Danone

In July 2004, Groupe Danone and United Biscuits announced that they had made an agreement for the latter to acquire Jacob's Biscuit Group.
