(author), TNO Kwaliteit van Leven (author)Pectin-derived acidic oligosaccharides (pAOS) are non-digestible carbohydrates to be used in infant formulae and medical nutrition. To support its safety, the genotoxic potential of pAOS was evaluated. pAOS was not mutagenic in the Ames test. Positive results were obtained in the chromosome aberration test only at highly cytotoxic concentrations...article 2010

(author), TNO Kwaliteit van Leven (author)The safety of a refined arachidonic acid-rich oil (RAO) was evaluated for reverse mutation, chromosome aberration and gene mutation, and in a 90-day Wistar rat feeding study with in utero exposure. The results of the genotoxicity assays were all negative. The in utero phase of the 90-day study involved dietary exposure to 0.5%, 1.5% and 5% RAO...article 2009

(author), TNO Kwaliteit van Leven (author)Polyunsaturated fatty acids (PUFAs), such as arachidonic acid (ARA) and docosahexaenoic acid (DHA) are natural constituents found in human milk, fish oil or egg yolk. Until recently, infant formulas, though providing the essential fatty acid precursors for these PUFAs, did not contain preformed ARA or DHA. In this study the safety of SUNTGA40S...article 2006

Lina, B.A.R. (author), Kuijpers, M.H.M. (author), TNO Voeding (author)The effects of diet-induced acid-base disturbances were examined in 4-week, 13-week and 18-month toxicity studies, and in a 30-month carcinogenicity study. Rats were fed a natural ingredient diet (controls), supplemented with 2% or 4% KHCO3 (base-forming diets), or with 1% or 2.1% NH4Cl (acid-forming diets). Additional controls were fed 3% KCl ...article 2004

Lina, B.A.R. (author), Jonker, D. (author), Kozianowski, G. (author), Instituut CIVO-Toxicologie en Voeding TNO (author)Isomaltulose is a natural occurring disaccharide composed of α-1,6-linked glucose and fructose. Commercial isomaltulose is produced from sucrose by enzymatic rearrangement and has been used as a sugar in Japan since 1985. It is particularly suitable as a non-cariogenic sucrose replacement and is favorable in products for diabetics and...article 2002
