Peppermint (Mentha piperita) is a perennial herb growing to the size of one meter, and is a hybrid from watermint (Mentha aquatica) and spearmint (Mentha spicata), used initially for culinary and food manufacturing purposes (mainly as a flavouring agent) but also has been used for its support of healthy digestive systems.

Mint has been used for health purposes for several thousand years. It is mentioned in records from ancient Greece, Rome, Egypt, and Persia.

Mint health benefits were recognised by Avicenna in his grand book titled “Canon of Medicine” more than a thousand years ago.

Avicenna was a Persian polymath who is regarded as one of the most significant physicians, astronomers, thinkers and writers of ancient Persia.[1]

Peppermint was not recognized as a distinct kind of mint until 18th Century. [2]

Peppermint has an oil component and numerous and extensive studies have proved peppermint oil can help support healthy digestive systems [3-5].  The relaxing effect of peppermint oil for gastrointestinal tract is due to the effect of peppermint oil in decreasing calcium influx into the smooth muscle cells [6]. It is wise to say that a healthy digestive system creates the necessary foundation and the very basis of a healthy body and a healthy mind.

Aetheroleum Menthae Piperitae is the essential oil of peppermint obtained by steam distillation of the fresh over-ground parts of Mentha × piperita L. The major constituents of peppermint oil are menthol (30-55%) and menthone (14-32%).

Any form of peppermint oil (liquid, enteric coated capsules, etc) should be effective for its support of digestive system. But please note enteric coated capsules have a polymer coating which is not a natural product and Gelatine type capsules normally contain bovine gelatine which is animal based and glycerine which is a chemical compound.

RELAMINTTM contains premium peppermint oil in its purest form in a carefully formulated liquid solution of food grade peppermint hydrosol, which is mainly result of exclusively prepared, Fresh-DistilledTM peppermint leaves which undergo a well monitored pasteurisation process. The ingredients of RELAMINTTM are sourced from carefully researched and audited suppliers. We know our ingredients are of the highest quality because our products are re-tested in qualified laboratories to ensure purity.

Peppermint Oil and Peppermint Oil food supplements are the subjects of increasing scientific and clinical interest because of the possible health benefits associated with their consumption [7-8].

The Pasteurisation Process of RELAMINTTM


Pasteurisation is a process of preservation of liquid food products by thermal destruction of microorganisms. Pasteurisation process has been named after scientist Louis Pasteur and basically requires application of heat to destroy human pathogens in foods. Correct pasteurisation of any food product requires well researched knowledge of the food characteristics.

For various foods, different pasteurisation techniques with different combinations of temperature and holding time can be utilised, but in order to have the right taste and safety measures for RELAMINTTM we at Meriole require our carefully selected partner producers of peppermint hydrosol to follow a strict guideline for pasteurisation process in terms of temperature and holding time.

Here we try to explain our pasteurisation of peppermint hydrosol process in simple terms and to describe how we at Meriole ensure that our products are made safe without using chemical preservatives.

Let’s start to firstly look at the temperature and holding times during pasteurisation.

Figure-1 below provides an easy to understand graph of pasteurisation process. The horizontal axis is the temperature, and the vertical axis is the holding time during pasteurisation.  Any combination of temperature and time which is on the right hand side of the pasteurisation curve can be used for preservation of peppermint hydrosol. Any point along the curve has the same degree of thermal destructibility.

Sounds simple? Ok, if it were so simple, RELAMINT’s pasteurisation process would not be anything special.  Please continue reading.

Figure-2 below now provides a similar curve to Figure-1, but this time the graph shows the cooking curve of peppermint hydrosol. Now you may start asking: what is a cooking curve?

We call it cooking curve because it is easy to understand. Cooking of any food involves heating the ingredients to a certain temperature with an aim to change its physical, chemical and/or taste characteristics. The higher temperature an ingredient is cooked at, the shorter time it takes to change its character. Therefore, cooking also involves a combination of heat and temperature.

By combining the curves in Figures 1 and 2, Figure-3 is created. This is where things get a bit more complicated. The ideal pasteurisation holding time vs. temperature is an area where the peppermint hydrosol is safely pasteurised but it’s character is maintained without being cooked. The ideal area is therfore somewhere on the right hand side of pasteurisation curve but on the left hand side of cooking curve. This area is shown by two hatched regions in Figure-3.

We at Meriole have also conducted further research to establish which combination of holding time vs. temperature during the pasteurisation process is the most economical way of preserving the main ingredient of RELAMINTTM.

Benefits of RELAMINTTM


RELAMINTTM contains peppermint essential oil as one of its main ingredients. Extensive research has shown the following benefits for peppermint essential oil and these are fully recognised as health benefits of peppermint essential oil as a food supplement in the EU:

– Helps to support healthy digestive systems;

– Contributes to destruction of pathogen microorganisms;

– Helps to support optimal functioning of respiratory system;

– Helps soothing of mouth and throat and has pleasant effect on throat, pharynx and vocal cords.

– Customers of RELAMINTTM have recommended it for relief from bloating and for those with inflammatory bowel conditions and IBS (Irritable Bowel Syndrome).

Always remember, food supplements should not be used as substitutes for a varied and balanced diet and healthy lifestyle.
