The adulteration of food, lessons from the past, with reference to butter, margarine and fraud

Abstract: The history of food adulteration and fraud and attempts at their control from the Middle Ages to date is traced for Belgium and for the UK with special reference to butter and margarine. The development of analytical procedures for the authentication of milk fat is outlined, from those based on the characterisation of fatty acids derived from milk fat in the nineteenth century to chromatographic methods in the next century and the recent rapid spectroscopic approaches. The importance of adequate surveillance programmes to reduce the incidence of food fraud is stressed.

Triglyceride composition of Buchanania lanzan seed oil.

Abstract: The fatty acid composition of Buchanania lanzan seed oil, determined by urea complex formation and gas liquid chromatography (g.l.c), was found to be: myristic, 0.6; palmitic, 33.4; stearic, 6.3; oleic, 53.7; and linoleic, 6.0%. Triglyceride compositions of the native seed oil and its randomised product were calculated from the fatty acid compositions of the triglycerides and of the corresponding 2-monoglycerides produced by pancreatic lipase hydrolysis. The oil is composed of 3.2, 35.8, 45.5 and 15.5% trisaturated, monounsaturated disaturated, diunsaturated monosaturated and triunsaturated glycerides respectively. The special characteristic of the B. lanzan seed oil is its content of 22.7, 31.0 and 11.3% dipalmitoolein, dioleopalmitin and triolein respectively. The percent GS3 content in the oil increased from 3.2 to 7.5 by the process of randomisation. On directed interesterification the oil yielded a product with a slip point of 41.5°C which may be suitable as a coating material for delayed action tablets. The oil also appears to be a promising one as a commercial source of palmitic and oleic acids.

Fette und Wachse

Abstract: Leinol kommt in den Samen des Flachses oder Leines (Linum usitatissimum L.) vor. Die hauptsachlichsten Lander, in denen Lein in bedeutenden Mengen zwecks Samengewinnung angebaut wird, sind Rusland, Indien, Nordamerika, Kanada und Argentinien. Im allgemeinen kann man die verschiedenen flachsbautreibenden Lander hinsichtlich des mit dem Leinbau verfolgten Zweckes in zwei ziemlich scharf getrennte Gruppen teilen, zu deren ersterer die Vereinigten Staaten von Nordamerika, Argentinien und Indien zahlen (Saatgewinnung), wahrend zur zweiten Gruppe (Faserverwertung) die meisten europaischen Lander, mit Ausnahme Ruslands, zu rechnen sind; dieses produziert sowohl Leinsaat, als auch Flachsfaser.
