Plant sterols are added as their FA esters to vegetable oil table spreads at levels of approximately 8% as a means to reduce blood cholesterol levels. A new chromatographic method was designed to quantify quickly the level of plant sterol FA esters in incoming (raw) materials and to monitor their processing and final product quality with respect...

A series of proteins was studied with respect to their ability to form a network at the air/water interface and their suitability as foaming agents and foam stabilizers. Proteins were chosen with a range of structures from flexible to rigid/globular: β-casein, β-lactoglobulin, ovalbumin, and (soy) glycinin. Experiments were performed at neutral...

Migration of low-molecular weight compounds is one of the most important problems of packaging plastics and other plastics intended to come into contact with food products. Since migration experiments are time consuming and expensive, predictive modelling has been introduced as a promising alternative. The main objective of this article is to...

Every other year scientists working in the field of residue analysis participate the "International Symposium on Hormone and Veterinary Drug Residue Analysis" and "Euroresidue" conferences. In each symposium a lot of innovative information is presented. In order to obtain a retrieval system for this growing amount of information, a database...

A method, based on microtoming and GC analysis, for studying migration of additives inside polymers as a function of space and time was validated for Irganox 1076 migrating from low-density polyethylene to ethanol. The consistency of the mass balance of the total amount of Irganox 1076 in the polymer and the solvent after different incubation...

Background: Conjugated linoleic acid (CLA), which is present in milk products and meat from ruminants, appears to have anticarcinogenic activity against breast cancer in animal and in vitro experiments. To date, few epidemiologic data are available in humans. Objective: This study evaluated the relation between intakes of CLA and other fatty...

A mass spectrometric approach was chosen to quantify and localise in vitro enzymatically modified glutamine (Gln) residues in a glutamine-rich protein. This protein (named dB1), a cloned domain of the high molecular weight wheat glutenin subunit Dx5, was modified by microbial transglutaminase (TGase) using hydroxylamine as the amine donor. Using...

Cruciferous vegetables, such as Brassica, which contain substantial quantities of glucosinolates, have been suggested to possess anticarcinogenic activity. Cutting and chewing of cruciferous vegetables releases the thioglucosidase enzyme myrosinase, which degrades glucosinolates to isothiocyanates and other minor metabolites. Cooking of...

Objective: To harmonize food classification and food composition databases, allowing comparability of consumption at both food and nutrient levels in Europe. Design: To establish the level of comparability at the food level, the EFCOSUM group benefited from the work already carried out within other European projects, which established a Euro...

Spreading of a drop of an emulsion made with milk proteins on air/water interfaces was studied. From an unheated emulsion, all oil molecules could spread onto the air/water interface, indicating that the protein layers around the oil globules in the emulsion droplet were not coherent enough to withstand the forces involved in spreading. Heat...

Objective: The aim of the EFCOSUM project was to develop a method to estimate both acute and usual consumption levels in European countries and for the sake of comparison, a common basic method for dietary assessment was needed. The method should allow a reliable comparison of the intake of relevant dietary indicators among large population...

This paper addresses major developments in the safety evaluation of chemical mixtures during the past 15 years, reviews today's state of the art of mixture toxicology, and discusses challenges ahead. Well-thought-out tailor-made mechanistic and empirical designs for studying the toxicity of mixtures have gradually substituted trial-and-error...

Objective: To describe the rationale and methods for a European project (EFCOSUM) to develop a method for a European food consumption survey that delivers internationally comparable data on a set of policy-relevant nutritional indicators. Rationale and methods: Currently Member States are collecting data and information for use at national level...

BACKGROUND. Several studies have reported inverse associations between folate intake and colorectal carcinoma risk. Few were prospective studies and none evaluated the association between the intake of individual folate vitamers and colorectal carcinoma risk. METHODS. The aim of the current study was to investigate the relationship between...

Objectives: The roles of retinol, vitamins C and E, and carotenoids as risk factors for prostate carcinoma are still questionable. We evaluated these in the Netherlands Cohort Study. Methods: The cohort study consisted of 58,279 men ages 55-69 years at baseline in 1986. After 6.3 years of follow-up, 642 incident prostate carcinoma cases were...

Transglutaminases can perform various reactions that are based on cross-linking, acyl-transfer and deamidation. These enzymes are found in many different organisms where they have very specific roles. The basic reaction mechanism of these transglutaminases is similar. The reactions catalyzed by transglutaminases have proven to be useful in...

The reduction in levels of organochlorine pesticide residues in food of animal origin in the past 30 years has been achieved especially by controlling entrance via the feed chain. A further reduction was achieved by registration and use of less persistent pesticides both for direct treatment of animals and of plant material. The remaining...

There is a growing need for transparency concerning ways in which existing exposure data are weighted for their relative value and quality. Currently, this evaluation is largely subjective and is dependent on the quality of the judgement of the individual assessor or expert group. In this paper some general guidelines are presented for a quality...
