PHARMACEUTICAL & NUTRACEUTICAL

Retention of active ingredients - Naturally

detox. young barley, chlorella superfood.Pharmaceutical and nutraceutical companies are increasingly using Flavourtech’s technologies in their production lines. A shift towards healthier lifestyles has dramatically increased the use of botanical-based nutraceuticals, such as functional extracts of herbs, vegetables and fruits. These botanical-based nutraceuticals are also increasingly being used in pharmaceutical products.

The active constituents in pharmaceutical products are some of the most difficult and sensitive compounds to process. Preserving these constituents, such as enzymes and proteins, is extremely important to the efficacy of the final product and critical in pharmaceutical applications.

Most of these active constituents are heat sensitive so their protection during the concentration stage of the manufacturing process is vital. Flavourtech’s Centritherm® evaporator offers manufacturers of pharmaceuticals and nutraceuticals a gentle way of concentrating or evaporating solvent from products without damaging their active properties.

Oil Capsules iStock_000000676000 411 xThe Centritherm evaporator is uniquely engineered, and its low temperature evaporation (from 25°C) and one second contact time on the heating surface is why it is fast becoming an integral production line technology for many multinational companies.

  • No damage to active ingredients during concentration (or solvent removal) and negligible thermal impact on the product, resulting in high quality, high potency concentrates
  • Exceptionally short residence times (about one second)
  • Low operating temperatures (from 35°C)
  • Low hold-up volume, making the technology ideal for processing small batches
  • High concentrations can be achieved without product recycle
  • Hygienic system suitable for pharmaceutical / nutraceutical certification

APPLICATIONS

Solvent removal from pharmaceuticals

iStock_000055573614_411 xFlavourtech’s Centritherm evaporator is used by leading international companies for concentration of, and solvent removal from, a range of pharmaceutical products including enzymes, proteins, vitamins, antibiotics, blood products and other chemical compounds.

Flavourtech’s Centritherm evaporator is not only ideal for the evaporation of organic solvents but also can be used to process flammable or toxic materials.

How it works

Active ingredients contained in many pharmaceutical products are prone to heat denaturation. The preservation of these compounds is of paramount importance, especially during the concentration stage where heat is applied to evaporate the solvent. To minimise thermal degradation and consequent loss of functionality the action of the spinning cones within the Centritherm evaporator reduces the contact time between the heating surface and the product to approximately one second.

Centritherm evaporators are usually operated with an evaporation temperature of 50°C and a steam temperature of 120°C. However, if the heat sensitivity of the product is particularly pronounced, these conditions can be adjusted to reduce the temperature difference and further reduce the thermal impact. For example, lower operating temperatures, from 35°C, and steam temperatures of 70 to 90°C are used when processing various enzymes and protein fractions in order to preserve maximum functionality.

This combination of short residence time and low evaporation temperature ensures concentrates produced by the Centritherm evaporator are of extremely high quality and efficacy.

Concentration of plant and herbal extracts

The production of plant extracts typically requires the following process steps:

  • Hand holding a test tube with plantExtraction of the active ingredient from the naturally occurring raw material using water or organic solvent.
  • Separation of the extract (now containing the active compound/s) from the spent raw material.
  • Evaporation of the water or organic solvent from the extract in order to increase the concentration of the active ingredient and produce a concentrated liquid extract.
  • The liquid extract may then be used as is, or further processed into a dry powder.

The Centritherm evaporator is an ideal unit for this application due to the combination of short residence time and low evaporation temperatures ensuring concentrates are of extremely high quality and fully functional.

Distillation of squalene from shark liver oil

Squalene is a unique substance that is found in high concentrations within certain varieties of shark liver oil (concentrations range from 25% to 80%). Squalene is a highly regarded health supplement (commonly sold as fish oil or shark liver oil), which is believed to  support the body’s immune system and help fight ailments ranging from colds and infections, through to arthritis and asthma.

How it works

To recover the squalene from the shark liver oil, Flavourtech offers a Centritherm evaporator that is designed for high vacuum, short path evaporation – also known as molecular distillation. The molecular distillation process produces a clear (water-like) distillate that has a high squalene concentration.

The Short Path Centritherm evaporator incorporates two stages:

  • Stage 1: Degas and pre-heat the oil using either a standard thin-film Centritherm evaporator or degassing unit.
  • Stage 2: Recover the squalene using a short path high vacuum Centritherm evaporator.

The Flavourtech system offers many advantages, including continuous processing and short residence times, and produces high grade squalene. The following image shows the two fractions recovered using this system.

Case Study

Sea Dragon NZ

Sea Dragon is New Zealand’s largest refiner and blender of high quality internationally certified Omega-2 and Omega-3 fish oils, sourced from fish caught in the clean and pure waters of New Zealand and the South Pacific. They supply high quality health supplements to manufacturers and marketers around the world.

Sea Dragon installed a Flavourtech Centritherm® evaporator in 2007 to remove ethanol from the refined oil with no thermal damage to the finished product. The Centritherm evaporator’s unique ability to process viscous products with only a one second heat contact time has enabled the efficient production of high concentration, quality products without any thermal damage.
