The Expert Committee commissioned to evaluate the safety for human consumption of selected food additives and contaminants and to establish acceptable daily intakes for these substanc. The report has two parts. The first part provides a general discussion of principles governing the toxicological evaluation of food additives and contaminants, the establishments and revision of specifications, and intake assessments of food additives. The second part provides succinct summaries of the toxicological data examined and factors considered when evaluating selected substances and allocating an acceptable daily intake. Evaluations are presented in this report for one antioxidant tert-butylhydroquinone , two emulsifiers microcrystalline cellulose and sucrose esters of fatty acids and sucroglycerides , two enzyme preparations alpha-acetolactate decarboxylase and maltogenic amylase , one flavoring agent trans-anethole , one glazing agent hydrogenated polydecene , one sweetening agent maltitol syrup , and the reduced calorie replacement for conventional fats and oils, salatrim. The second part is dedicated to revision of specifications on aluminium powder, iron oxides and titanium oxides; aluminium lakes of coloring matters, hydroxypropyl cellulose, magnesium sulphate, polyvinyl alcohol and metal levels and arsenic specifications. The third part deals with eight groups of flavoring agents such as pyridine, pyrrole and quinoline derivatives; aliphatic and alicyclic hydrocarbons; aliphatic, linear, unsaturated aldehydes, acids and related alcohols, acetals and related esters; monocyclic and bicyclic secondary alcohols, ketones and related esters; amino acid and related substances; tetrahydrofuran and furanone derivatives and Phenyl substituted aliphatic alcohols and related aldehydes and esters.

The risk assessment of residues of veterinary drugs in food is a field that continues to evolve. The toxicological end-points to be considered are becoming more nuanced and in light of growing concern about the development of antimicrobial resistance, detailed analysis of the antimicrobial activity of the residues of veterinary drugs in food is increasingly incorporated in the assessment. This publication describes in detail the consideration of acute and chronic effects, the estimation of acute and chronic dietary exposure, current approaches for including microbiological endpoints in the risk assessment, and JECFA's considerations for the potential effects of food processing on residues from veterinary drugs. JECFA now applies these approaches in the development of health-based guidance values i. JECFA, thus, comprehensively addresses acute and chronic risks by using corresponding estimates for acute and chronic exposure and suitable correction for the limited bioavailability of bound residues by the Gallo-Torres model.

Its conclusion is one of the most important testimonials that can be given to a food additive and its reviews carry significant weight in global regulatory decisions on food additives. In its monograph on carrageenan JECFA said that it had considered a toxicological dossier on carrageenan Republic of the Philippines and a commentary on studies published by an academic research laboratory Tobacman In compiling its report JECFA placed significant weight on new research related to the safety of carrageenan, particularly a feeding study of neonatal piglets. JECFA said, in part, "The Committee noted that although the MOEs margins of exposure are small in magnitude, they are derived from a neonatal pig study in which the highest dose tested was without adverse effects on the gut or on immune parameters. These new studies allay the earlier concerns that carrageenan, which is unlikely to be absorbed, may have a direct effect on the immature gut. The Committee also took account of the previous toxicological database on carrageenan, which did not indicate other toxicological concerns. Roger A.

It has been meeting since , initially to evaluate the safety of food additives. JECFA has evaluated more than 2, food additives, approximately 40 contaminants and naturally occurring toxicants, and residues of approximately 90 veterinary drugs. The Committee has also developed principles for safety assessment of chemicals in foods that are consistent with current thinking on risk assessment and take account of developments in toxicology and other relevant sciences.
