Food & Pharmaceuticals

High-quality technologies for the extraction of flavours

SCHRADER: Your specialist in high-quality technologies for the extraction of flavours, active ingredients and fragrances for the cosmetics and food industries, as well as high-purity active ingredients for the pharmaceutical industry.

SCHRADER specialises in the engineering and construction of extraction plants with and without downstream evaporation, distillation or rectification, as well as plants for preparation- and mixing-technology. The processes used in the food, pharmaceutical and cosmetics industries are based on the same technologies and are customized to your requirements – all the way up to the creation of a turnkey plant.

Much more so than the food industry, the pharmaceutical industry demands the highest levels of quality, reproducibility and diligence. What is more, SCHRADER attaches particular importance to qualification, as well as to development and production in compliance with standards. Complete documentation on the basis of FDA (Food and Drug Administration) regulations or GMP (Good Manufacturing Practice) guidelines is absolutely essential.

As a matter of principle, SCHRADER carries out the following qualification and validation activities for your plant in line with Annex 15 of the EU GMP guidelines:

Design qualification (DQ)

Factory acceptance test (FAT)

Installation qualification (IQ)

Operational qualification (OQ)

Performance qualification (PQ)

Food industry

The European Commission’s food hygiene package has been in force in Germany since 1 January 2006. It pertains to centralised food monitoring, places higher requirements on primary production (raw materials and additives), regulates the combination of food and animal feeds and tightens requirements for labelling and traceability. It is implemented throughout Germany via the Food and Feed Code (LFGB).

Pharmaceutical industry

The EC GMP guidelines Part 1 for medicinal products and Part 2 for active ingredients are implemented throughout Europe. Throughout Germany, the manufacture of pharmaceuticals and active ingredients is prescribed by the German Medicines Act (AMG) and is implemented in law by the Ordinance on the Manufacture of Medicinal Products and Active Ingredients (AMWHV).

Cosmetics industry

The GMP guideline is based on DIN EN ISO 22716 GMP for Cosmetics. Regulation (EC) No 1223/2009 on cosmetic products contains regulations on composition and labelling information, restrictions for certain substances, safety assessments as well as requirements for market surveillance and registration.

Natural (i.e. naturally occurring in nature) flavours, fragrances and active ingredients are extracted from plant, animal or microbiological raw materials using enzymatic, microbiological and/or physical processes. The interaction between the raw material and the solvent is just as important as the individual adjustment of temperature, resting time, pressure and dosage. SCHRADER uses all parameters to develop the perfect plant for every client.

Vanilla extract, for example, is of enormous importance and is used in food, perfume and personal care products.

Vanilla extract

Vanilla extract is a liquid extract made from vanilla pods in a ethanol-water mixture, sometimes with the addition of sugar syrup. Pure vanilla extract may only be extracted from real vanilla pods; it contains all the aromatic substances of vanilla in a high concentration and has a practically unlimited shelf life. Vanilla extract is mainly used in industrial food production, where vanilla pods of different qualities and origins are combined in such a way that the consistent quality of the extract is always guaranteed. It is used in food, perfumes and personal care products.

There are many raw materials that are suitable for the production of extracts:


e.g. valerian, chamomile, St. John’s wort


e.g. mint, sage, thyme, eucalyptus, tea, tobacco, cannabis


e.g. vanilla, chilli, carob


e.g. liquorice, ginger, turmeric, ginseng, rhubarb

Animal products

e.g. cheese, meat, fish, feathers, hooves, glands

Extraction of flavourings, fragrances, active ingredients

Woody plants, barks

e.g. sandalwood, cola, birch, cinnamon

Seeds, kernels

e.g. cocoa, coffee, dill


e.g. moulds, shiitake


e.g. citrus fruits, berries, olives


e.g. clove, pepper

In the food industry,

on request all plants are designed in such a way that production processes can be guaranteed within the framework of religious food rules (halal and kosher).

In the pharmaceutical industry,

precise dosing and mixing are essential to produce homogeneous products of consistent quality. By designing suitable agitator vessels, SCHRADER guarantees reliable and efficient preparation and mixing technology. Turnkey plants guarantee safe and verifiable production which is made to measure – from implementing the recipe instructions to the monitoring and documentation of all parameters.

Individual plants and high-performance technologies for a wide range of applications

The first step of the process workflow is extraction. The choice of extraction process is determined by the type of product to be extracted and the quantity of raw material (substance or mixture of substances). Processes such as evaporation, distillation and rectification can be integrated into the plant concept as required. Other such processes include mixing, dissolving, sterilising, cleaning, homogenisation and roasting, as well as upstream processes such as grinding, chopping and swelling.


Separation process which uses an extraction agent to extract one or more components from a substance or mixture of substances.


Heating a chemical solution to achieve the required extract concentration by evaporating off the solvent. The concentrated solvent can then be processed by means of rectification.


Thermal process for the incomplete separation of liquid mixtures.


A special form of distillation in which the distillation process is repeated several times to ensure complete separation of the liquid mixtures.

We work to exceed your expectations

We manufacture individual and highly specialised systems according to your specifications and in line with the applicable regulations. Based on your objectives, your process overview and the evaluated parameters, we develop and document a plant concept which is optimal in terms of energy efficiency, sustainability and process safety.

Als GMP bezeichnet man Richtlinien zur Sicherung der Qualität in den Herstellungsabläufen von Arzneimitteln, Wirkstoffen, Lebensmitteln, Futtermitteln und Kosmetika. Insbesondere in der Pharmaindustrie hat Qualitätssicherung eine besondere Bedeutung, da Qualitätsabweichungen direkten Einfluss auf die Gesundheit haben können. Zur GMP gehören je nach Produkt und Verwendung:

  • Vermeiden jeglicher Art von Kontamination (totraumfrei)
  • eindeutige Produktkennzeichnung
  • gleichbleibende, reproduzierbare Produktqualität
  • Qualitätsanforderungen an Endprodukte, aber auch an Roh- und Hilfsstoffe
  • Rückverfolgbarkeit
  • qualifiziertes Personal (Ausbildung und Schulung)
  • geeignete Produktionsanlagen und -räume
  • Festlegen, Umsetzen und Einhalten von Hygieneanforderungen

Da keine einheitliche GMP-Leitlinie existiert, werden die Produktionsanlagen entsprechend der Gesetze und Verordnungen der Industrie ausgelegt, in der das Produkt später verwendet wird.  Der Umfang der notwendigen GMP-Maßnahmen wird durch die GMP Risikoanalyse festgestellt und vertraglich festgehalten.

Good Manufacturing Practice (GMP) is the term used to describe the guidelines for ensuring quality in the production of pharmaceutical products, active ingredients, foodstuffs, animal feed and cosmetics. Especially in the pharmaceutical industry, quality assurance is of particular importance, as quality deviations can have a direct impact on health. Depending on the product and its use, GMP may involve:

  • Avoiding any kind of contamination (dead space free)
  • Clear product labelling
  • Consistent, reproducible product quality
  • Quality requirements for end products, but also for raw materials and additives
  • Traceability
  • Qualified personnel (education and training)
  • Suitable production facilities and premises
  • defining, implementing and maintaining with hygiene requirements

As no uniform GMP guideline exists, production facilities are engineered in accordance with the laws and regulations of the industry in which the product will later be used.  The scope of the GMP measures which are required is determined by the GMP risk analysis and written into a contract.
