The aflatoxin (I) content of peanut cake is substantially reduced by a process in which the contaminated cake is heated with an ammonia-containing neutralisation paste at 80-120 deg.C. The neutralisation paste contains water, ammonia soaps, and 10-20% excess of ammonia over that required to neutralise fatty acids. It may be made by either of the following methods: (a) soap stock from the refining of fats is acidified, eg. with sulphuric acid then neutralised with excess aqueous ammonia, or (b) during the refining of fats, neutralisation is effected with ammonia, rather than with sodium hydroxide. The decontaminated prod. is suitable for use as an animal feed. The process is simpler to operate than prior art methods of eliminating (I), the prod. is enriched with good quality nutritive lipids, and a low value by-prod., the neutralisation paste, is utilised. |
