Non-invasive wine taint detector

Abstract

A system includes a computing device including a memory configured to store instructions. The computing device also includes a processor to execute the instructions to perform operations including initiating transmission of incident light from one or more light sources to a sealed bottle containing liquid. The operations also include receiving scattered light from the liquid contained in the sealed bottle. The operations also include processing one or more signals representative of the scattered light to detect interactions of the incident light with a particular molecule.

         7 . The computing device implemented method of  claim 1 , wherein the particular molecule is trichloroanisole or methanethiol. 
     
     
         8 . The computing device implemented method of  claim 7 , wherein processing comprises determining from the interactions of the incident light with the trichloroanisole molecule or methanethiol if the liquid is tainted. 
     
     
         9 . The computing device implemented method of  claim 1 , wherein processing one or more signals representative of the scattered light comprises determining if the received scattered light is above a threshold value. 
     
     
         10 . The computing device implemented method of  claim 1 , wherein the light source comprises a laser. 
     
     
         11 . A system comprising:
 a computing device comprising:   a memory configured to store instructions; and   a processor to execute the instructions to perform operations comprising:
 initiating transmission of incident light from one or more light sources to a sealed bottle containing liquid; 
 receiving scattered light from the liquid contained in the sealed bottle; and 
 processing one or more signals representative of the scattered light to detect interactions of the incident light with a particular molecule. 
   
     
     
         12 . The system of  claim 11 , wherein the liquid is wine.
