摘要:

The current toxicological status of sulphiting agents is reviewed, including evidence of adverse reactions to sulphited foods by a sub‐population of asthmatics. Against this background are assessed the applications and benefits of sulphiting agents in foods. It is concluded that further information is required to determine the magnitude of risk and that, in the interim, the controlled use of sulphiting agents is justifiable.

摘要:

Interest has increased recently in the possible human carcinogenic effects of plant metabolites in the diet. Some psoralens, some pyrrolizidine alkaloids and ‘bracken carcinogen’ may be dietary carcinogens, the latter two via contamination of food products from animals ingesting toxic plants. With the exception of ‘bracken carcinogen’, the structures of these compounds have been established. Further research to quantify the levels of these compounds in foodstuffs and to correlate these with the amounts of the compounds having toxic effects in laboratory animals would be valuable. Epidemiological studies on critical‐intake consumer groups would also be of value in defining the hazard, if any, the presence of these compounds in the diet poses to the consumer.

摘要:

Urinary rhamnose estimations following ingestion of gum karaya were requested by the Scientific Committee for Food (EEC) in July 1983. Five male volunteers have therefore made 24‐h urine collections prior to, and following, the ingestion of 10 g gum karaya for 15 days, an intake ten‐fold greater than that approved in terms of the present temporary ADI (0–12.5 mg/kg b.w.). Paper chromatographic separations, with two solvent systems, were made on the fresh urine specimens and also after ten‐fold enrichments of all urinary constituents. Standard aqueous solutions of rhamnose, and urine to which rhamnose had been added, showed the detection limit to be 0.2 μgrhamnose. Independent examinations in two laboratories failed to detect rhamnose at this level in any of the urine specimens. Had 1% of the rhamnose present in 10 g gum karaya appeared in the 24‐h urine specimens, it would have been detected. This confirms previous evidence that dietary gum karaya is neither digested nor degraded by enteric bacteria and is not absorbed to any significant extent in Man.

摘要:

To monitor the use of synthetic growth promoting hormones in red meat animals requires a sensitive and rapid method of analysis. This paper describes the development of such a method for these agents in bile, based on a high pressure liquid chromatographic purification procedure with detection and estimation by radioimmunoassay.

摘要:

An immunoassay for the xenobiotic anabolic compound methyltestosterone (MT) is presented. The detection is based on chemiluminescence of a MT‐isoluminol conjugate. Applications are presented for detection of methyltestosterone and cross‐reacting compounds in bovine urine and tissues of application sites isolated from slaughtered cattle, illegally treated with hormonal anabolics.

摘要:

An automated headspace capillary column GC‐MS method using selected ion monitoring was developed for the analysis of ethylene dibromide (EDB) residues in fresh fruits. The method was shown to be rapid, to give good agreement with more conventional methods involving distillative extraction, to be free from interferences and to have a limit of detection of 1μg/kg. A small survey of a range of fresh fruits including oranges, grapefruit, lemons and mangoes showed no detectable EDB residues in a total of 45 samples obtained from various retail outlets.
