SCHEDULE 2Control of Feed Materials
Part IPrincipal processes used for the preparation of the feed materials listed in Part II of this Schedule
Process | Definition | Common name or term | |
|---|---|---|---|
(1) | (2) | (3) | (4) |
1 | Concentration(1) | Increase in certain contents by removing water or other constituents | Concentrate |
2 | Decortication(2) | Complete or partial removal of outer layers from grains, seeds, fruits nuts and others | Decorticated, partially decorticated |
3 | Drying | Dehydration by artificial or natural processes | Dried (sun or artificially) |
4 | Extraction | Removal either by organic solvent of fat or oil from certain materials or by aqueous solvent of sugar or other water-soluble components. In the case of the use of organic solvent, the resulting product must be technically free of such solvent | Extracted (in the case of oil-containing materials), molasses, pulp (in the case of products containing sugar or other water-soluble components) |
5 | Extrusion | Pressing of material through an orifice under pressure. (See also pregelatinisation) | Extruded |
6 | Flaking | Rolling of moist heat-treated material | Flakes |
7 | Flour milling | Physical processing of grain to reduce particle size and facilitate separation into constituent fractions (principally flour, bran and middlings) | Flour, bran, middlings(3), feed |
8 | Heating | General term covering a number of heat treatments carried out under specific conditions to influence the nutritional value or the structure of the material | Toasted, cooked, heat treated |
9 | Hydrogenation | Transformation of unsaturated glycerides into saturated glycerides (of oils and fats) | Hardened, partially hardened |
10 | Hydrolysis | Breakdown into simpler chemical constituents by appropriate treatment with water and possibly either enzymes or acid/alkali | Hydrolysed |
11 | Pressing(4) | Removal by mechanical extraction (by a screw or other type of press), with or without a slight heating, of fat/oil from oil-rich materials or of juice from fruits or other vegetable products | Expeller(5) (in case of oil-containing materials) Pulp, pomace (in case of fruits, etc.) Pressed pulp (in case of sugar-beet) |
12 | Pelleting | Special shaping by compression through a die | Pellet, pelleted |
13 | Pregelatinisation | Modification of starch to improve markedly its swelling properties in cold water | Pregelatinised(6), puffed |
14 | Refining | Complete or partial removal of impurities in sugars, oils, fats and other natural materials by chemical/ physical treatment | Refined, partially refined |
15 | Wet-milling | Mechanical separation of the component parts of kernel/grain, sometimes after steeping in water, with or without sulphur dioxide, for the extraction of starch | Germ, gluten, starch |
16 | Crushing | Mechanical processing of grain or other feed materials to reduce their size | Crushed, crushing |
17 | Desugaring | Complete or partial removal of mono- and disaccharides from molasses and other material containing sugar by chemical or physical means | Desugared, partially desugared |
