Definitions

  • fatty oils - of vegetable or animal origin - contain impurities which must be removed before the oil is suitable for consumption. Also fatty oils for technical use often have to be purified to some extent to make them suitable for their purpose.
  • the removing of impurities could be carried out by a degumming and/or winterization process and may be combined into one process a so-called cold degumming process.
  • the traditional cold degumming process is not always successful because:
  • the present invention solves the above mentioned technical problems by the new inventive method.
  • the present invention relates to a new method for treating vegetable oils and/or animal fats to reduce the content of impurities, such as various phospholipids i.e. gums, wax and/or high melting glycerides.
  • impurities such as various phospholipids i.e. gums, wax and/or high melting glycerides.
  • One aspect of the invention to provide a method for efficiently removing both the phospholipids and the high melting glycerides by phospholipase at the same time.
  • Another aspect of the invention to provide a method for utilizing the enzyme reaction feature such as the reacted gum has lower viscosity and less emulsification strength to achieve less oil loss.
  • the main purpose of a degumming process is to remove phospholipids from the oil.
  • oil types such as sunflower seed oil, rice bran oil, corn oil, winterization process is needed to remove the high melting glycerides to avoid problems in the use of the oils at lower temperature or in later process.
  • the enzymatic degumming process has been proven effective in gum removal.
  • the phospholipids are converted to lyso-phospholipids and free fatty acids i.e. FFA.
  • the lyso-phospholipids have much less emulsion capacity and lower viscosity. So, it is expected that the separation at lower temperature in enzymatic degumming process is much better than in a conventional process.
  • lyso-phospholipids are water-soluble, it is expected that most lyso-phospholipids will stay in the water phase during wax crystallation and crystal growth, so that the inhibition due to the presence of gums is eliminated.
  • the cold enzymatic degumming process will provide the possibility of making degumming and dewaxing simultaneously, and with significant low loss of neutral oil
  • the new method for treating vegetable oils and/or animal fats according to the invention comprises the following steps:
  • step (i) the temperature of the vegetable oils and/or animal fats may be adjusted within the range from about 60 to about 90°C.
  • the vegetable oils and/or animal fats may be treated with acid from about 1 to about 60 minutes, preferably from about 5 to about 60 minutes, most preferred from about 20 to about 40 minutes.
  • the pH in step (iii) may be adjusted with lye to a pH within a range from about 4 to about 8 at a temperature preferably from about 40 to about 60°C.
  • the lye in step (iii) is selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium silicate, sodium carbonate, calcium carbonate, and a combination thereof, preferably sodium hydroxide or potassium hydroxide. According to the invention the mixing of the lye in step (iii) may be continued within the range from about 1 min to about 4 hours.
  • the temperature of the aqueous mixture in step (v) may be adjusted by a cooling rate and by a residence time to optimize crystallisation, preferably by a cooling rate within the range of from about 0.5 degrees per hour to about 5 degrees per hour, and a residence time within the range of from about 4 to 24 hours, preferably from 6 to 12 hours.
  • the temperature of the aqueous mixture in separation step (vi) may be adjusted to facilitate separation, preferably the temperature is within the range of from about 15 to about 50°C.
  • the enzyme in treatment step (iv) may be a phospholipase enzyme, preferably one or more phospholipase A enzymes, or one or more phospholipase C enzymes, or a combination thereof.
  • the acid used in step (ii) is selected from the group consisting of phosphoric acid, acetic acid, citric acid, tartaric acid, succinic acid, and a mixture thereof, preferrably phosphoric acid or citric acid.
  • the equipment used in this experiment was an oil bath, Erlenmeyer flasks 500 ml, magnetic stirrer with heating and temperature control, an Ultra Turrax, a laboratory centrifuge.
  • FFA is analyzed according to method according to American Oil Chemists' Society, AOCS, Ca 5a-40, moisture is analyzed according to method AOCS Ca 2b-38, and phosphorus is analyzed according to method DIN EN 14107.
  • the crude sunflower seed oil was heated in oven to 70°C to ensure all the wax crystals are melted and dissolved in the oil.
  • A normal enzymatic deep degumming
  • B cold enzymatic deep degumming
  • a citric acid solution i.e. 5 ml
  • a sodium hydroxide solution was prepared, i.e. 5 ml, by dissolving 0,5075g sodium hydroxide pellets in distilled water.
  • the oil bath for flask A is heated to 80°C to inactivate the enzyme; while flask B was moved together with the magnetic agitator to fridge (7 - 8°C), and the agitation was kept at ca. 40 rpm for an overnight.
  • flask B and the magnetic agitator were removed from the fridge, and the agitation was kept at room temperature (about 22°C) for ca. 15 min.
  • the oil from flask B was centrifuged for 5 min. at 2000X g and the moisture, FFA and phosphorus content in the light phase were analysed.
