bulge a random chili con carne into your mouth is the culinary combining weight of play Russian roulette . Some are mild and pile with feeling , while others will make you feel like you ’ve just prick into the Earth’s surface of the sun . Without knowing where a chilly is from it ’s knockout to know how hot it is , so researchers from Thailandcreated a smartphone accessorythat canmeasure the warmth .
While most hardware built by researchers looks like it was assembled from random salvaged part receive in a drudge ’s dust - filled service department , theChilica - Pod , created at Thailand ’s Prince of Songkla University , really see like something you could find on the ledge of a Williams - Sonoma store . Shaped like an actual chili , the sensor plug into instantly to a smartphone and interfaces with an app to provide a measurement of the amount of capsaicin inside a chile , which is the specific ingredient that brings the heat . The gamey the concentration of capsaicin there is , the hotter a chili con carne will be , but measuring that usually requires bulky research laboratory equipment . The light answer , if you ’re not comfortable with the heat , is to ordinarily just skip chilis tout ensemble as an component option .
But with the Chilica - Pod users should be able to cursorily valuate what the experience of eat a give chilli will be like before they subjugate their mouths to all the hurting and agony . The sensor apply single - use , paper - establish mental test strips that contain graphene nanoplatelets ( flimsy sheets of graphene in short stacks ) enhanced with nitrogen molecule to improve their electric conduction . A small sample of a chili pepper , which can be fresh or dried , is mixed into a solution containing ethanol which is then added to the paper funnies in small drops . The capsaicin in the drop oxidizes when introduced to the nitrogen - raise graphene which make an electric electric current that can be measured . The more current the detector detects , the higher the concentration of capsaicin in the chili being test .

The Chilica - Pod has been tested on six dissimilar dried chili pepper samples by the squad that created it , and so far it has shown a stratum of accuracy on equality with the lab - based hardware and methodologies currently used to measure capsaicin levels in food . The system is n’t quite as self - contained or foolproof as something like a breathalyser is — it still requires the sampling to be mingle into a solution and adulterate before being lend oneself to the psychometric test strips — so do n’t expect to apace apply the Chilica - Pod before digging into a dish . But it could one Clarence Day be useful in the kitchen , for both professional chef and menage Captain James Cook who need to check that they wo n’t accidentally be subject anyone to an unpleasant experience .
