Lactic Acid: Glucose Fermented over Chalk, Freed with Sulphuric Acid
Technical lactic acid is made by fermenting sugar. Thorpe's Dictionary (1912) gives McLauchan's method: glucose, chalk and a little malt in water, started with a spoonful of sour milk and kept at 45 °C for six days. The chalk keeps the liquid neutral so the bacteria keep working, and the acid collects as calcium lactate. As in the works, sulphuric acid then sets the lactic acid free: a colourless, sharp-tasting syrup. Joining the two is our choice.

CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
