Global Filter Provides Separation Solutions to the Flavorings, Fragrances, and Edible Oils Industry

The flavoring, fragrances, and edible oils markets are some of the largest when it comes to products intended for human consumption. Derivatives of all types of naturally occurring substances are in everything we consume, and we do without even thinking much about what goes into creating them.

One of the most critical parts of creating flavors, fragrances, and edible oils, most of which are derived from plants, is separating the product from the by-product. For example, lemon oil is extracted from lemon peel by removing it from the fruit, squeezing the peels under extreme pressure, and purifying the resulting oil. No matter the source producing a pure, consistent product is key. Whether the goal is eliminating undesirable flavor characteristics, optimizing color & clarity, or maximizing shelf life, Global FIlter’s extensive line of liquid filtration products fits the bill.

Edible Oils Typical Processing & Filtration

Filtration Process Steps

Step 1: Raw product is washed to remove any chemicals or debris that may have accum during the growing season, harvest, or transport. Water used in this equipment is recirculated through a basic particulate filter. For this step we recommend using our GB Series bag filters. They will capture any large debris that may restrict nozzles and to reduce the amount of water required for washing.

Step 2: After washing, the raw product is processed for oil extraction. Raw products are processed in different ways some may be separated, while others processed whole. The desired components will be crushed and pressed to extract oils. Screw presses are commonly used. It is very efficient at extracting a high percentage of oils.

Step 3: Oil is filtered by a basic particulate filter. For this step, we recommend using our GB Series bag filters, to prevent large particulate build-up in storage tanks downstream. This is also first step in processing oils.

Step 4: Oil is sent to storage tanks until enough has been extracted to continue processing. The storage tank has a vent filter that allows it to fill or drain without creating positive pressure or vacuum. Global Filter’s PP Series pleated depth polypropylene cartridge will prevent intrusion of particulate but other options, like the PTFE Series membrane cartridge, will prevent the introduction of particulates, moisture, or microorganisms.

Step 5: Once there is enough oil in storage to blend and process into the final product it is once again filtered. The PP Series pleated depth polypropylene cartridges are a great option for this step, which is normally a two-stage process filter to 10 microns absolute.

Step 6: Oil is blended with any flavorings, colors, or preservatives that will maximize shelf life and ensure oil is the correct color and consistency.

Step 7: Once blended, the product is filtered one last time to ensure anything added during blending is fully dissolved and the product is of uniform consistency. For this step, we usually recommend using our sub-micronic pleated depth PP Series or lenticular particulate filters GSD-Series. If needed membrane cartridges may also be used for final filtration. In this case, we recommend using our GFPES Series membrane cartridges.
