Flavors and Fragrances are blends of aromatic organic compounds composed of natural, nature identical and/or synthetic ingredients. Natural flavor and fragrance substances are concentrated through processes of distillation, mechanical separation or extraction. After blending and prior to packaging for shipment, most flavor and fragrance products must be filtered to achieve a desired standard of clarity, color and stability. Various degrees of filtration from clarifying to final polishing filtration are required. Depth filters play a major role in assuring the highest degree of quality.
ErtelAlsop manufactures a wide range of cellulose depth filter media for use with flavor and fragrance applications, which fit our wide selection of filtration equipment. Various degrees of filtration from product clarification to final polishing filtration are demanded by flavors and fragrances. Depth filters play a major role in assuring the highest degree of quality. ErtelAlsop depth media succeeds in filtering diverse natural and synthetic flavor aroma chemicals, essential oils, oleoresins, distillates, extracts and liquid compounds.
Flavor chemists formulate blends of materials to product extracts or liquid compounds. Depth filtration plays a critical role in the process to ensure the end product satisfies the customer.
Common applications include:
Particulate and Haze Reduction: ErtelAlsop Micro-MediaÆ depth filter media provides an ideal solution for reducing particulate loading in a wide variety of flavor products, effectively removing fine particulate that may collect over time at the bottom of product packaging.
Essential Oil Absorption: ErtelAlsop 100% Cellulose Alpha-Mediaô filter media is used in flavor extract applications to absorb free oil remaining in the extract after it is chilled and decanted. The cellulose depth matrix provides simultaneous particulate and haze reduction.
Removal of insoluble waxes/lipids: Filtration ensures haze and wax residue will not be visible when the product is chilled or blended.
Removal of microbial contaminants: Finer grades of depth media offered by ErtelAlsop can remove microbial contaminants as well as byproducts of fermentation processes.
Water Removal: Unwanted water contamination is sometime present in essential oils after extraction, either residual from the raw materials, or introduced in the manufacturing process. This water appears as a haze in the material, increasing the turbidity readings of the product. ErtelAlsop Zeta-Dri Pak Lenticular technology succeeds at removing water from essential oils during the filtration process. Both particulate and water can be removed in one pass through a Zeta-Dri Pak system.
Expert perfumers within the fragrance industry draw from a diverse palette of essential oils and other fragrance materials and combine them in unique ways to produce scents that are enjoyed in a variety of products including fine fragrance, personal care, home care and home design products. The filtration of essential oils removes haze, particulate and possibly filter aids which were used in the refinement of these liquids.
The blending of essential oils with alcohols, water and other base solvents can result in the formation of additional haze or precipitates in the final product. Filtration of chilled fragrances through ErtelAlsop depth filter media is the quickest, most consistent and cost efficient means of polishing these liquids prior to filling.
Common Applications Include:
Particulate and Haze Reduction: ErtelAlsop Micro-MediaÆ filter media provides a trusted solution to the varying degrees of filtration required by fragrance producers.
Color correction: In some cases, color removal is essential for the presentation of a fragrance product. ErtelAlsop Micro-Clearô filter media with activated carbon is the perfect solution for these filtration applications. The carbon impregnated filter media can be used in existing filtration equipment, removing the need to contaminate processing tanks with loose activated carbon. The process fluid can be recirculated through the filter media to achieve the required level of contact time with the activated carbon. Color correction and particulate removal can be achieved in one step.
Vapor Control: An ErtelAlsop Vapor- MasterÆ Enclosed Plate and Frame Filter Press allows for the both containment of vapors and the treatment of liquid with filter aids. This technology is ideal for applications where solids collection is required, but the product is also highly volatile and potentially flammable.
Filter Press Technology
ErtelAlsop filter presses are a flexible and durable solution for the filtration of flavors and fragrances. Our sanitary, fully stainless steel equipment is built to match the requirements of your application. The plate and frame design with a blanking plate allows for filtration of a wide range of batch sizes.
ErtelAlsop filter press product line ranges from lab scale to commercial scale units, allowing for a smooth, linear industrialization process, with predictable performance at any scale from development to manufacturing.
In addition to being fully cleanable, our new patented BioCleanô Filter Plate Assembly provides the ability to completely drain a plate and frame filter press. Supplied in conjunction with our state of the art air over oil hydraulic closure, which minimizes leakage and reduces loss to a minimum, ErtelAlsop is uniquely positioned to provide the ultimate in plate and frame filter press technology.
Pak Lenticular Media Technology
Our Pak Filter Housings are well-suited to filter volatile liquids like perfumes and fragrances. The housing is an enclosed system with a small footprint when compared to the large amount of filter area contained in each Pak Lenticular cartridge. The higher flow rates achieved in this style of depth filter, combined with the rapid media change out capability make it ideal for high-volume, low-solids polishing applications.
