Guest guest Posted August 15, 2006 Report Share Posted August 15, 2006 I decided to give Liberty a call, and spoke to someone who was helpful and informative (and patient!) he said that Liberty buys this as a natural absolute from a producer in India that they have been dealing with for a very long time. as far as Liberty knows it's not diluted (and Liberty does not dilute themselves). i am going to experiment with other absolutes that i have collected and see how they act with oil. i already know that Liberty's cocoa absolute does not mix with fixed oils. i have 2 varieties of cocoa absolute, one from Liberty, and another from a source that i respect very highly. i will try them both in oil to see if they react differently. (i'll also try water). could it be possible that when saffron is grown, only the best gets used for the culinary market? perhaps the inferior saffron pieces get used to make absolute? (perhaps as a byproduct of the culinary industry?) only someone who has visited the producers would really know, as anya mentioned. -linda The Perfumer's Apprentice www.perfumersapprentice.com Quote Link to comment Share on other sites More sharing options...

Below is an excerpt from an email that of Liberty Natural follwed up with, when I had asked if he could check for the documentation on this absolute ******************************** Dear ..... As there has been much interest lately in the Saffron absolute, I've had an opportunity to gather all the available information regarding the item. The Saffron comes from a reputable supplier; a distiller in India that we have been in business with for a decade or more. (As our computerized records only go back to the mid 1990's it is difficult to tell exactly when our relationship began without digging through a few filing cabinets). The distiller indicates that the item is pure, natural, and uncut. As a result you can expect the item to be free of adulterants. One must remember that all solvent extracted items, including absolutes, will retain a trace amount of the solvent used in the extraction process. Having had a chance to review the mass spectrometer plot for the item, I've found it to conform to the expected standards of an unadulterated absolute with no peak data indicating the presence of synthetics or other contaminants. - Quote Link to comment Share on other sites More sharing options...

I wonder if they would be willing to share their analytical findings. It still concerns me that this saffron absolute is completely water-soluble. The fact that other absolutes may also be wholly water-soluble is not reassuring either. Some aromatic molecules do possess some water solubility, but this degree of hydrophilicity and lipophobicity surely does not make sense in any genuine absolute. Adulteration in the form of " extending " with a non-aromatic material is not something I know much about, but I know there are a number of possible extenders, and I believe that some may be difficult to spot on a gc trace.

Hi , Well, you got me to rumage through a stash of old oils to find some of the " so called " Saffron Absolute. Surprisingly, as also found, it is water soluable. And as I remembered from some years ago - it also separates from fixed oils. There are many absolutes (resinoids, oleoresins, etc) that do not blend with fixed oils, however, it is the way in which the Saffron absolute separates from the fixed oil that is very suspicious to me. It doesn't look or feel right. It looks and acts differently than when I try to blend cocao absolute, vanilla absolute, balsam of peru resin, benzoin, labdanum etc. I certainly do not know if it is extended with DPG, but the way that it separates is how an oil in DPG acts. That was the first clue. That it blends completely in water is the second clue. Water solubility is an atribute of DPG (or similar chemical in the same family: ethylene glycol, propylene glycol, etc.). DPG feels like an oil, and yet it is completely water soluble. I forgot to actually feel the Saffron Absolute while I was in the shop, but try feeling it between your fingers, and see if it feels just like a fixed oil does. (Another idea is to put it on some blotter paper and see what happens when it dries out.) The third clue is the price. The fourth clue is that I do not see Saffron Absolute listed on (any that I remember) reputable manufacturers or suppliers product lists. I do see Saffron Oleoresin and such occassionally, but haven't checked them out (but now I will). This field of Essential Oils, Absolutes, etc. is full (very full) of misinformation, disinformation, adulteration, substitution, sophistication, extending, etc. etc. Even fully trained, professional eo chemists can not tell you 100% truthfully that an oil is not adulterated in one form or another by looking at a GC/MS (if it was professionally adulterated). But they can offer their professional opinions. The Saffron Absolute to me is a rather obvious one to be very suspicious of. I bet it sells well though. I have seen another so called Saffron Absolute from India and it was much the same, I haven't seen the one that Anya mentioned...

Different solvents are used in the 2 step process for making absolutes. Typically hexane is used in step 1, but there are a whole host of other solvents that can be used. Each different solvent has the potential to affect the final product, and so different manufacturers will use different solvents depending on what they are looking for. The second step solvent is typically alcohol (ethyl alcohol, ethanol). There is usually a trace and sometimes up to 4 % or so of the alcohol left in the absolute. If an absolute blends pretty well into a fixed oil, yet partially separates out after a few days time - this is an indication that there may be more than a trace of alcohol in the absolute. Sometime a small percentage of alcohol is intentionally left in the absolute to allow it to be more pourable, and this causes no concern for the alcohol perfumer, but can be troublesome to the fixed oil blender. The first step solvents are typically completely removed from the absolute (detectable at the ppm level only) so the answer to your question would most of the time be - no. If a solvent other than alcohol was used in the second step or a unique method of extraction (such as the butane extracted " butaflors " ) was performed it very well could make a difference. But these extractions are not common. And, please remember that there are a few solvents such as DPG that are fairly commonly added (added - after extraction) to resinoids and some other very thick and un-pourable materials simply to make them pourable. Pourable Benzoin is the most common example... I believe that the answer as to why some absolutes blend in fixed oils and others do not (and why most blend perfectly into alcohol, yet some blend imperfectly) has to do with the actual constituents in the absolutes, that were extracted from the plant material, rather than the solvents used to extract the product from the plants. (I do not know the chemistry here... such as which constituents in Vanilla are not soluable, etc...) Best to do is to take Salaam's advise and put up a new bottle on your shelf with dried saffron and alcohol in it and make your own tincture. Then you will be sure what you have. And to keep looking for the perfect Vanilla absolute.... Will Eden Botanicals Quote Link to comment Share on other sites More sharing options...

Then that makes me think that it could be then used as a coloring agent. Of course then problem comes that perfume must be mixed then on water solubility. Is this ok thinking/ possible? When I get home I' do a test. I bought a small quantity (maybe 3 oz.) of saffron, non edible, for altar offering from a Tibetan vendor for $5 Hope this helps Bb __________________________________________________ Quote Link to comment Share on other sites More sharing options...
