How can I introduce a 100% ethanol extract into a dairy product knowing that when I evaporate the ethanol, I obtain a dry extract that is insoluble in water and soluble in DMSO?
I would recommend using 70-80% Ethanol instead of pure ethanol then you go for an evaporation process i.e. Rotary Evaporation and you will obtain a concentrated aqueous extract that would be feasible to incorporate into diary products.
Muhammad Nouman Shaukat hello, your recommendation is good to receive a concentrated extract. but in my country, a test to show no ethanol is available in the food is necessary. moreover, ethanol in even low concentration would affect microbial growth and probably sensory parameters of dairy products.
