Definitions

  • the present invention relates to a method of removing unwanted components from an aqueous flow derived from the processing of edible products having a natural origin.
  • the invention is directed to the separation of compounds like lysophospholipids from an aqueous process stream in the processing of cereals, fruits, seeds, tubers, nuts, berries and the like, e.g. from a starch containing slurry in the preparation of glucose by conversion of grains like wheat and corn.
  • a rotary vacuum filter comprises a perforated drum with a cloth, which drum is rotably mounted upon a longitudinal axis. The outer circumference of the drum is covered with a precoat like perlite or diatomaceous earth, having an initial layer thickness of about 10cm. The fluid flow of starch hydrolysate is applied to the outside of the drum and sucked into the interior through the perforations by vacuum.
  • a further object of the invention is to reduce the overall amount of unwanted matter in a food processing flow such as a starch containing process flow, in particular to decrease the level of lysophospholipids .
  • Still another object of the invention is to reduce the level of fats, proteins and suspended solids as well.
  • the present invention provides a method of removing unwanted components from an aqueous flow derived from the processing of edible products having a natural origin, which method comprises the steps of adding a treating agent comprising at least one compound selected from the group comprising at least one fatty acid or a acylglycerol derivative thereof, to the aqueous flow in an amount sufficient to transfer the unwanted components from the aqueous flow to the treating agent, and separating the aqueous flow from the treating agent comprising the unwanted components.
  • the method according to the invention comprises the treatment of an aqueous flow. This aqueous flow is derived from the processing of edible starting materials having a natural origin into products for consumption by humans or animals, i.e. food products and feed products .
  • These starting materials having a natural origin comprise agricultural and horticultural products, and fruits.
  • Examples comprise vegetables e.g. spinach and cabbage, grains including cereals and seeds e.g. wheat, corn, barley and sorghum, tubers like potatoes and sugar beets, fruits e.g. oranges, apples and berries, and others, e.g. sugar cane, chichorei, casave.
  • this aqueous flow is treated with a medium essentially containing at least one fatty acid or an acylglycerol derivative thereof, preferably oils in view of water insolubility and density difference.
  • the two streams are contacted in order to transfer the unwanted compounds from the aqueous phase to the treating agent. Low shear forces may be applied.
  • the unwanted components to be removed comprise compounds, the presence of which is undesirable in the products to be obtained from the aqueous flow concerned or which compounds interfere with the processing itself of the aqueous flow.
  • the aqueous flow is derived from the processing of edible starting materials having a natural origin.
  • the treatment method according to the invention is carried out during this processing.
  • the aqueous flow resulting from the treatment according to the invention is the main flow comprising the (intermediate) products for consumption.
  • the flow comprising the treating agent and unwanted matter that has been removed, is considered as a by stream.
  • the unwanted components do not comprise only contaminants or impurities to be discarded.
  • the compounds themselves may be valuable e.g. from nutritional point of view.
  • the unwanted components to be removed are selected dependent on the nature of the aqueous flow.
  • the components are selected from the group comprising lysophospholipids, phospholipids, fats, proteins, pesticides, organoleptic compounds, mycotoxines, tannins, suspended solids, pentosanes, enzymes and heavy metal complexes.
  • Organoleptic compounds comprise flavours, aromas, colourants and odour compounds.
  • the unwanted compounds comprise lysophospholipids, phospholipids, fats, proteins and suspended solids.
  • the unwanted components have an oleophilic nature or proteinaceous nature.
  • the unwanted components have an amphipatic nature. I.e. they have both polar and non-polar ends, and in addition are big enough for each end to display its own solubility behaviour.
  • the polar end is water-soluble (hydrophilic) and the non-polar end is water-insoluble (lypophilic) .
  • any unsoluble proteins are present in the aqueous food processing flow, for the greater part they form a complex together with the components to be removed in particular LPL's, and oil, and consequently they are simultaneously removed.
  • the wheat oil predominantly contained in the germs themselves have been removed in a stage prior to the conversion of starch into glucose, because the presence of this oil would otherwise affect the quality of the end product.
  • the unwanted compounds are still incorporated in inclusion complexes and cannot be extracted simultaneously with the wheat oil.
  • FIG. 1 shows an embodiment of a device for carrying out the method according to the invention.
  • the fatty acid or the fatty acid(s) of the acylglycerol of the treating agent has preferably a chain length of 14 to 20 carbon atoms, preferably 16 to 18 carbon atoms.
  • the length of the non- polar chain influences the separation amongst others.
  • the acylglycerol may be a mono-, di- or triacylglycerol.
  • the at least one fatty acid is selected such that the chain length thereof is essentially similar to the chain length of the compounds to be removed.
  • the treating agent is of food grade quality.
  • the treating agent comprises an oil of natural origin, such as a vegetable oil or animal oil.
  • Suitable examples of a vegetable oil include sunflower oil, palm oil, palm kernel oil, coconut oil, rapeseed oil and soy oil.
  • Fish oil is an example of a suitable animal oil. Sunflower oil having a high oleic content, and palm oil because of efficiency are more preferred.
  • the treatment according to the invention will preferably also reduce the content of other components such as fats, insoluble proteins and suspended solids in the aqueous flow. It is believed that suspended solids and in particular the insoluble proteins are partially entrained by the oil phase during phase separation, and are partially complexed by the oil. The simultaneous reduction of the fat and protein level is advantageous because otherwise these impurities are to be removed in an additional step.
  • Processing aids in order to enhance the polar and/or hydrophobic interactions can also be used, whether they are present originally in the oil or added thereto on purpose. Processing aids may also be used with a view to increasing the effect of the density difference between the aqueous phase and oil phase.
  • the method according to the invention is preferably performed on an aqueous flow comprising carbohydrates or derivatives thereof.
  • a hydrolysate which is obtained by acid or enzymatic conversion of e.g. corn or wheat, is a preferred process flow to be treated.
  • the pH of the aqueous food processing flow may vary broadly. E.g. the method according to the present invention can be performed in the pH range from 2 to 8. Commonly known acids and alkaline compounds can be used to adjust the pH value. At the higher level (pH > 5.5) saponification may occur, therefor advantageously the pH is in the range from 3 to 5.5.
  • the temperature may be raised, e.g. up to 100°C, preferably in the range of 70-90, e.g. 80°C provided that the quality of the aqueous flow and the end product to be attained therefrom are not deteriorated.
  • the viscosity is reduced resulting in a faster separation between the aqueous phase and the phase of the treating agent.
  • the treating agent and aqueous flow are contacted intimately in order to increase the interaction between the different phases and thus the transfer of unwanted components from the aqueous phase to the treating agent.
  • formation of a stable emulsion should be prevented.
  • Conventional mixing will do, e.g. a common propeller mixer, spraying the aqueous phase into a bath of oil or vice versa, purging gas and the like. Low shear mixing is preferred in batch wise operation. Contact time and separation time can easily be determined by experimentation.
  • Oil tracers e.g. "Opacity Blue” can be used to determine an adequate separation.
  • the amount of oil to be added depends on the amount and type of components to be removed. Based on conventional levels of components in wheat hydrolysate the volume ratio between oil and hydrolysate may vary within broad limits. In batch wise operation good results have been obtained in the range of 1:99 - 16:84, while the jlower ratios e.g. 2:98 show even better results.
  • the method according to the invention is preferably carried out under non-oxidizing conditions, more preferably in an inert atmosphere like carbon dioxide.
  • the components to be removed by the method according to the invention have already been illustrated herein above. In a typical starch hydrolysate flow these components ( fats and proteins, except suspended solids) make up 2 wt.%, approximately 0.1-1% being LPL's.
  • the aqueous food processing flow treated according to the invention could be further processed in a conventional manner, e.g. a starch slurry to a glucose syrup.
  • the treating agent containing the unwanted components can be regenerated by removing these components. Then the treating agent is available for reuse, and allows a continuous process.
  • FIG. 1 shows diagrammatically a basic design of a device for carrying out the method according to the invention.
  • This device comprises a holding tank 10.
  • the tank 10 is provided with an inlet 12 connected to a supply line 14 for supplying an aqueous food processing flow into the tank 10.
  • An upright baffle 16 connected to the bottom and side walls of the tank 10 provides an overflow for separation of the light oil phase from the relatively heavy water phase, and divides the tank into two compartments 18 and 20 respectively. Both compartments are provided with outlets, an outlet 22 provided in bottom 24 for discharging treated aqueous phase and an outlet 26 for discharging the oil phase.
  • Oil is added to the tank 10 by a conduit 28, which is arranged in compartment 18, e.g.
  • the oil phase discharge outlet 26 may be connected to a further separation device 30, wherein the contaminants are separated from the oil. Then the purified oil can be returned to the conduit 28 by return line 32. Make up oil can be supplied via a line 34.
  • the thus purified aqueous food processing flow leaving outlet 22 can be further processed in a conventional manner.
  • sample A the sample after the pH adjustment
  • sample B the aqueous glucose phase after separation
  • sample C the oil phase after separation
  • Sunflower oil high oleic seems the best oil type to use followed by palm oil. Rapeseed oil can also be used for the extraction of the LPL but the fat content of the glucose juice after the extraction compared to the experiments with the sunflower oil and palm oil is higher. pH and temperature are also important parameters that can vary dependent on the oil type used.
