Oils and fats production
LTD "Innosystems" offers project of oil and fat products production in accordance with HACCP, ISO and Global GAP international standards.
The oil and fat products used for edible purposes can be divided into two distinct classes: liquid oils, such as olive oil, peanut oil, soybean oil, or sunflower oil; and plastic fats, such as lard, shortening, butter, and margarine. The physical nature of the fatty material is unimportant for some uses, but the consistency is a matter of consequence for other products. As a dressing on green salads, for example, a liquid oil is used to provide a coating on the ingredients; a plastic fat such as lard or butter would be unsuitable. Spreads for bread, foods that require a highly developed dough structure, or icings and fillings with a plastic structure require plastic fats rather than liquid oils.
For reasons related to both history and climate, there are pronounced geographic patterns of consumption of fats and oils. The ancestors of the present inhabitants of central and northern Europe obtained their edible fats almost exclusively from domestic animals. The food habits and the cuisine depended on the availability of plastic fats; and butter, lard, margarine, and shortening continue to be their primary fatty food materials. In contrast, population pressures in the older civilizations of the Orient and the Mediterranean countries of southern Europe, northern Africa, and the Middle East have long since made extensive raising of livestock impractical, necessitating that the edible oils of these regions be derived primarily from intensively cultivated vegetable crops.
More than 90 percent of the world production of fats and oils is used in edible products, and the objective of most processing steps is to convert crude fats of low palatability or undesirable physical form into refined products that meet the regional requirements for food fats. The annual consumption of visible fats—such as lard, butter, shortening, or salad oils that have been separated from the original animal or plant source—ranges from 18 to 25 kilograms (40 to 55 pounds) per person in various highly industrialized European countries to 23 kilograms per person in the United States.
About 40 percent of the dietary fat in the developed countries comes from isolated fats and oils, with 60 percent obtained from basic foods, whereas in the less developed countries most of the dietary fat is obtained from fruits, cereals, vegetables, dairy products, and meats, and relatively little is consumed in the form of isolated fat products.
The raw materials for the fat and oil industry are animal by-products from the slaughter of cattle, hogs, and sheep; fatty fish and marine mammals; a few fleshy fruits (palm and olive); and various oilseeds. Most oilseeds are grown specifically for processing to oils and protein meals, but several important vegetable oils are obtained from by-product raw materials.
