organic extraction via solvent | Bookmark | ||||||
SWIM has around 1 cup of dried and crushed jalepeno peppers, and wished to use IPA to extract and concentrate the active ingredient (the one that makes it spicy). Short of using a soxhlet extraction process, is it possible to get a yield just soaking the peppers in the IPA then straining...what is left upon evapping the IPA? an oil? keep in mind this isn't SWIM's attempt at making hash oil, SWIM is trying to do what is described above. Why? |

There are a lot of ingredients in there. Capasin (sp?) being the primary one. Without a steam distillation you will have to use a variety of solvents to get what you want. Check the Merck for solubilities. |

tricks are for kids ;) SWIM really likes it's tricks ;) hot sauce of course ;), SWIM's not sure if it's hot sauce is gonna bee the best that SWIM can make short of using the soxhlet or any other glassware for that matter, the IPA is tangerine in color after being strained a la coffee filter... after the IPA evapps off, SWIM'll update on the result of the end product to evaluate if that's the way to make hot sauce or not Why? |
