How To Remove Water from Oil-based Flavor

Why is water removal from oil-based flavors important?

Oil-based flavors are often derived from plant components rich in essential oils. Citrus flavors are a typical example. Citrus aroma is obtained from the fruit's peel during orange and lemon juice production. The citrus oil contains water components that are primarily separated by separators or coalescers. Traces of water can remain after this step and may be visible as phase separation on top of the liquid.

How can water traces be removed from essential oils?

Seitz® ZD depth filter media is the key solution for efficient water removal from essential oils. The 100% pure cellulose matrix of the sheet media adsorbs water traces in the cellulose fibers while the essential oil passes through the filter media during filtration. Fine particles and haze that remain are also removed during this process.

Trace water can be achieved with the following depth filtration options:

SUPRAdisc II ZD lenticular depth filter module

SUPRAdisc™ II ZD lenticulars

SUPRAdisc II ZD combines the SUPRAdisc II design for lenticular sheet-based modules with pure cellulose depth filter sheet media. The filter is designed to give excellent filtration performance and lower filtration costs. SUPRAdisc II ZD filter modules are available in multiple grades and are also suitable for microbial reduction, fine filtration and clarifying filtration in various food and beverage applications.

Seitz ZD depth filter sheets

Seitz ZD (Zero DE) depth filter sheets consist of pure cellulose filter sheet media and are designed to give excellent filtration performance while respecting product quality to a high standard. Seitz ZD filter sheets are available in multiple grades and are also suitable for microbial reduction, fine filtration and clarifying filtration. Depth filter sheets made of 100% pure cellulose fibers allow water to be effectively adsorbed in the cellulose fibers while particles that may be left behind are removed in parallel.

SUPRApak™ ZD Series depth filter modules

Developed to meet the needs of the Food and Beverage industry for filter sheet media, the SUPRApak ZD Series combines a 100% cellulose depth filter sheet matrix with the SUPRApak design and its unique “edge flow” principle. Edge flow technology optimizes the depth filter matrix, allowing for a very high filtration area per module. Multiple passes of the liquid through the sheet media extend the contact time of the water with the cellulose fibers and enable an optimized water separation effect.
