SCOPE This Standard applies to
2、oils and fats and mixtures thereof in a state for human consumption. It includes oils and fats that have been subjected to processes of modification (such as trans-esterification or hydrogenation) or fractionation. This Standard does not apply to any oil or fat which is covered by one of the followi
3、ng: the Codex Standard for Named Animal Fats; the Codex Standard for Named Vegetable Oils; the Codex Standard for Olive Oils and Olive-pomace Oils. 2. DESCRIPTIONS 2.1 Edible fats and oils are foodstuffs defined in Section 1 which are composed of glycerides of fatty acids. They are of vegetable, ani
4、mal or marine origin. They may contain small amounts of other lipids such as phosphatides, of unsaponifiable constituents and of free fatty acids naturally present in the fat or oil. Fats of animal origin must be produced from animals in good health at the time of slaughter and be fit for human cons
5、umption. 2.2 Virgin fats and oils are edible vegetable fats and oils obtained, without altering the nature of the oil, by mechanical procedures, e.g. expelling or pressing, and the application of heat only. They may be purified by washing with water, settling, filtering and centrifuging only. 2.3 Co
6、ld pressed fats and oils are edible vegetable fats and oils obtained, without altering the oil, by mechanical procedures, e.g. expelling or pressing, without the application of heat. They may have been purified by washing with water, settling, filtering and centrifuging only. 3. FOOD ADDITIVES 3.1 N
7、o additives are permitted in virgin or cold pressed oils covered by this Standard. 3.2 Colours No colours are permitted in vegetable oils covered by this Standard. CODEX STAN 19 Page 2 of 6 The following colours are permitted for the purpose of restoring natural colour lost in processing or for the
8、purpose of standardizing colour, as long as the added colour does not deceive or mislead the consumer by concealing damage or inferiority or by making the product appear to be of greater than actual value: Maximum level 100 Curcumin or Turmeric 5 mg/kg (calculated as total curcumin) 160a Beta-carote
