"A PROCESS OF SEPERTING A COMPOUND CONTAINING ALLYLISOTHIOCYNATE FROM MUSTARD SEED"
|Abstract||The invention "A process of separating a compound containing Allylisothiocynate from mustard seed " is a new technique of isolating Allylisothiocynate from mustard seed. Mustard oil is known for its pungency and medicinal properties.The medicinal properties of mustard oil are due to Allylisothiocynate. The process which is sought to be patented isolates this compound from the oil, thus leaving the oil with superior quality, no bitterness, low FFA(less than 1%) and shiny yellow colour. The compounds having 0.5% allylisothiocynate on mass basis has the antifungal, antibacterial and insecticidal properties. This compound is highly hygroscopic and is water soluble , thus, making it possible to be used in form of spray for the control of the insect, microorganism and for various purposes namely skin treatments, herbal insecticide and as a moisture absorbent.|
|Full Text||3.1 Introduction-Mustard is one of the most important oilseeds in the country and mustard oil ranks number two after groundnut oil. In Ayurveda and other healing methods, the properties of mustard oil as and fungal, anti-bacterial and insecticidal have been highlighted. These properties are basically due to presence of Allyl-isothiocynate in the oil and that it is why the direct use of mustard oil for these purposes is generally advised. In the process developed by us the compound has been isolated leaving the oil which is cleaner, has low FFA and is non-bitter.
3.2 Problem- Generally the mustard oil is obtained by expelling the seeds in the mechanical expeller, which is an inefficient expelling device as it leaves considerable oil in the cake, further the consumer of mustard oil especially in the Eastern region prefer it because of its typical pungency. The solvent extraction method of mustard oil is much superior as it leaves only negligible (less then 1%) oil in the cake but has one negative aspect namely the dissolution of soluble waxes and gums in the oil, which increases its FFA. The FFA of solvent extracted oil is higher than the expeller oil, so the people like the oil from expeller which is having low FFA.
3.3 Advantages-The compound isolated from mustard oil not only has the properties associated with mustard oil but being in concentrated form is much more effective. Further the oil, from which it has been isolated, is of much superior quality as it is almost transparent, less sticky and has low FFA. Such light colour oil has potential to be used as salad oil and also perhaps as a hair oil, thus, adding the value of mustard oil many folds,
3.4 Prior technique The properties of mustard oil highlighted in the Ayurvedic and other healing systems have been utilized in the treatments for microbial, fungal, bacterial and other ailments and also as insect repellent material. In this process, the oil as a solute of these compounds was used as such This not only causes wastage of edible oil but also caused much stickiness leaving stains on the cloth. This was due to unawareness of the people about the compounds responsible for such properties.
3.5 Description of present invention -The dried mustard seed are taken and rough ground in a grinder. The ground material is poured in boiled water and constantly stirred. The colour of the water starts becoming yellowish and is removed through a discharge pipe and collected, more water is poured into the vessel and coloured water is kept on being collected. This process of pouring fresh water and collection of coloured water goes on till the colour of the discharge water disappears. The collected coloured water is then heated and water is removed through constantly stirring. This concentrated material is put in the microwave oven for further dehydration. The dehydrated material is then ground in a mill in form of fine particles This material is highly hygroscopic so dehydration is done very carefully so that there is no opportunity of absorbance of moisture from the air. The vacuum drying is preferred to overcome this problem. The ground material is kept in a sealed package.
The following test results of this material have been obtained.
1. A process for separating a compound containing Allylisothiocyanate from mustard seed by:-
i. Rough ground of mustard seed in a grinder.
ii. Boiling the grounded seed in hot water.
iii. Removing the yellow colour water by draining from the grounded seed.
iv. Yellow colour water is boiled and water is removed through constant stirring
until a dark brown compound is obtained,
v. The compound is further dehydrated in the microwave oven until it becomes
vi. The compound now obtained is grounded in a mill to get fine particles.
