| titleOfInvention | Improvements in or relating to the extraction of non-fatty materials from animal or vegetable materials |
| abstract | Animal or vegetable material is subjected to intense impacts delivered through the medium of a suitable liquid to disrupt its structure under such conditions that a substantial proportion of the solid residues of the material is not reduced to colloidal or near-colloidal size, and non-fatty substances are recovered from the mixture. The process is applicable to the extraction of organ extracts from animal organs (e.g. Vitamin B12 from livers), glandular extracts from glands (e.g. insulin from pancreas), essential oils and flavourings such as lemon essence and vanilla. If the desired substance is water-soluble, water may be used as a liquid and the desired substance recovered from solution. Alternatively the liquid may be one in which the desired substance is insoluble but in which at least part of the residue is soluble. Organic liquids which may be used include hexane and petroleum fractions, trichlorethylene, carbon tetrachloride, alcohols, glycols and ketones. The extraction may be carried out in a hammer mill using a volume of liquid 1 to 30 times that of the material to be extracted. The examples describe the extraction of Vitamin B12 from ox liver and vanilla extract from vanilla pods and beans. Specifications 714,671, 722,311, [both in Group III], and 742,537 are referred to.ALSO:Animal or vegetable material is subjected to intense impacts delivered through the medium of a suitable liquid to disrupt its structure under such conditions that a substantial proportion of the solid residues of the material is not reduced to colloidal or near-colloidal size, and non-fatty substances are recovered from the mixture.
