.6 Fruit sugar preserves technology; jams‚ jellies‚ marmalade‚ fruit paste Contents - [pic]Previous - Next[pic] As a overall rule of thumb‚ a sugar concentration of about 60% in finished or processed fruit products generally insures their preservation. Preservation is not only determined by the osmotic pressure of sugar solutions but also by the water activity values in the liquid phase‚ which can be lowered by sugar addition; and by evaporation down to 0.848 aw; this value however does not protect

The different types are made by using different strains of the yeast Saccharomyces cerevisiae and by changing the fermentation process. Malting: Barley is soaked in water and spread out to germinate When shoots appear the barley is dried to stop further growth During the germination enzymes change starch in the grains to sugar. When getting heated the malt changes

is consisting mainly of acetic acid ( CH3COOH ) and water. It is produced in the commercials by either fast or slow fermentation. It is made from the oxidation of ethanol in an alcohol-containing liquid‚ such as wine‚ fermented fruit juice‚ or beer. In slow fermentation or in traditional‚ fermentation proceeds slowly over the course of months or a year. While the longer fermentation period allows for increase of a nontoxic slime composed of acetic acid bacteria.In fast production processes‚ vinegar

proven records of brewing are about 6‚000 years old and refer to the Sumerians. Sumeria lay between the Tigris and Euphrates rivers including Southern Mesopotamia and the ancient cities of Babylon and Ur. It is said that the Sumerians discovered the fermentation process by chance. A seal around 4‚000 years old is a Sumerian "Hymn to Ninkasi"‚ the goddess of brewing. This "hymn" is also a recipe for making beer. No one knows today exactly how this occurred‚ but it could be that a piece of bread or grain

molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch fermentation. This starch comes from grains such as wheat and maize. Fermentation is produced by a yeast culture. The digestion of starch by yeasts is done in two stages: the starch is initially hydrolyzed in sugars by a chemical or enzymatic process then sugars are converted into alcohol and
