摘要:

The dietary intake of cyclamate was evaluated in the north‐east of Spain in 1992. In a random sample of the Catalan population consisting of 2450 people aged 6–75 years, two 24‐h recalls at different seasons were collected; the amount and type of all foods, drinks and drugs consumed were obtained and the total daily intake of cyclamate was expressed in mg/kg body weight (bw), as the average of both 24‐h recalls. Eighteen percent of the population consumed cyclamate, and the highest percentage was in men aged 35–44 years (33%). Average daily intake of cyclamate was 0.44 mg/kg bw in the whole population and 2.44 mg/kg bw among consumers. Subjects following a diet reported highest intakes, especially diabetics, and only 0.16% of the sample studied had levels above the Acceptable Daily Intake (ADI). Among consumers, the intake of cyclamate was negatively correlated with Body Mass Index (BMI). The results show the pattern of cyclamate intake in the Spanish population.

摘要:

Hydrochloric acid (HCl) is used in the food industry as a processing aid in the manufacture of certain foods. HCl is manufactured, either directly from inorganic sources, i.e. ‘on‐purpose’ or indirectly as a by‐product from the production of organic compounds generally intended for non‐food applications. By‐product HCl potentially may contain traces of the manufactured product, its precursors, and other reaction by‐products. Many of the potential contaminants are volatile organic compounds (VOCs) such as vinyl chloride and benzene. A study was conducted to determine whether there were differences between the levels of VOCs found in HCl samples collected from two on‐purpose HCl manufacturers and two by‐product HCl manufacturers. Process water used to manufacture the HCl also was analysed. Twenty‐nine VOCs were determined by purge‐and‐trap concentration and capillary gas chromatography/mass spectrometry. Of these, nine were found in the process water and in both the by‐product and on‐purpose HCl samples at total VOC levels of less than 116 ng/ml. The levels of total VOCs identified in the two on‐purpose HCl samples were 58 and 80 ng/ml; the levels of total VOCs identified in the two by‐product samples were 41 and 115 ng/ml. The process water appeared to be the source of most of the contaminants. These results show that the levels of VOCs found in the two types of acid are comparable.

摘要:

An investigation was carried out to determine whether isooctane and ethanol behave like sunflower oil as fatty simulants for overall and for specific migration from PVC containing aromatic plasticizers (bis‐2‐ethylhexyl phthalate and tris‐2‐ethylhexyl trimellitate). In these films, the partition coefficients of migrants between simulant and polymer play a major role. The affinities of isooctane and of sunflower oil to all migrants were similar and isooctane can be considered as an alternative fatty simulant for plastized PVC. In contrast ethanol displays a different selectivity, and is not an adequate fatty simulant. Guidelines for the selection of solvents to be used as fatty simulants for migration testing are discussed. The scope of spectroscopic methods (FTIR and1H‐NMR) to monitor migration of aromatic plasticizers is presented.
