Abstract
A stable water-soluble product is obtained from the latex of lactuca virosa by separating the freshly gathered latex into a liquid portion and an inactive solid portion. The latex is preferably mixed with water and then separated by filtering, centrifuging &c. The liquid portion may be stabilized by addition of reducing agents or acids, e.g sulphurous acid, sodium bisulphite, formaldehyde, tartaric acid, citric acid and also by destroying the oxydases by heating to 80 DEG C. Preservatives may be added for preventing the formation of mould. The liquid product may be evaporated to dryness.
