食品添加劑與食品安全
隨著食品工業(yè)和添加劑工業(yè)的快速發(fā)展,食品添加劑的種類和數(shù)量越來越多,食品添加劑已經(jīng)成為食品生產(chǎn)加工和儲存過程中不可缺少的重要原料。然而,近年來有關(guān)食品添加劑的安全事件屢屢發(fā)生,造成了嚴(yán)重的后果,產(chǎn)生了惡劣的影響,食品添加劑的使用所引起的食品安全問題引起全社會的廣泛關(guān)注。食品添加劑是指為改善食品品質(zhì)和色、香、味以及為防腐、保鮮和加工工藝的需要而加入食品中的人工合成或天然物質(zhì),目前,我國允許使用的食品添加劑有2300多種,此外還有200多種營養(yǎng)強(qiáng)化劑。食品添加劑在食品工業(yè)中發(fā)揮著重要作用,不僅能夠改善和提高食品色、香、味及口感等感官指標(biāo),而且可以保持和提高食品的營養(yǎng)價(jià)值。但是,食品添加劑也是一把雙刃劍,它既給我們的生活帶來了便利,促進(jìn)了現(xiàn)代食品工業(yè)的發(fā)展,又易被不法分子利用超范圍、超標(biāo)準(zhǔn)使用和濫用違禁添加劑,給食品質(zhì)量、安全衛(wèi)生以及消費(fèi)者的健康帶來巨大的損害。因此,加強(qiáng)對食品添加劑安全問題的研究,提升我國食品的科技含量,推動(dòng)我國食品工業(yè)的快速發(fā)展,對于建立和完善我國食品安全體系,促進(jìn)社會和諧穩(wěn)定有著重要意義。

Primary mutagenicity screening of food-additives currently used in Japan
M. Ishidate Jr; T. Sofuni; K. Yoshikawa; et al.
Abstract:Salmonella/microsome tests (Ames tests) and chromosomal aberration tests in vitro using a Chinese hamster fibroblast cell line were carried out on 190 synthetic food additives and 52 food additives derived from natural sources, all of which are currently used in Japan. Fourteen out of 200 tested in the Ames assay showed positive effects and 54 out of 242 were positive in the chromosome test. Three additives (erythorbic acid, chlorine dioxide and beet red) were positive only in the Ames test, although their mutagenic potentials were relatively weak, while 43 additives were positive only in the chromosome test. Eleven additives (calcium hypochlorite, cinnamic aldehyde, L-cysteine monohydrochloride, Food Green No.3 (Fast Green FCF), hydrogen peroxide, potassium bromate, sodium chlorite, sodium hypochlorite, sodium nitrite, cacao pigment and caramel) were positive in both the Ames test and the chromosome test. The usefulness of such primary screening tests combining two different genetic end-points, gene mutation and chromosomal aberration, and some correlation between mutagenicity and carcinogenicity of food additives are discussed. A semi-empirical model has been developed for additive diffusion in polymers. The model estimates apparent diffusion coefficients of an additive migrating through polyolefin polymers into a fatty food simulant for a range of temperatures between the glass transition and melting temperatures of the polymer. This diffusion model has been applied to several additive/polyolefin systems to determine its validity and limitations. Progress made by the Flavor and Extract Manufacturer’Association Expert Panel, which was formed in response to the provision in the 1958 Food Additive Amendment (USA) that exempted those substances generally recognized as safe (GRAS) from food additive status, is reviewed. Flavouring ingredient GRAS substances are tabulated. Use of food additives is regulated qualitatively in the European Common Market through the EEC directives on food additives, while the concept of acceptable daily intake (ADI) provides a quantitative expression of safe amounts for the guidance of regulatory agencies. It is suggested that a permissible quantity or quantities, the ceiling, should be agreed upon for each permitted additive on the basis of its ADI and in accordance with the procedure described here, the estimation of intake of food and drink starts from the child, who on the basis of body weight has the highest consumption. When dealing with total intake (expressed as energy, weight or volume per kg body weight per day), occupational and climatical variations between adults are largely contained in the difference between child and adult. It is possible to calculate the highest concentration in foodstuffs which is consistent with the ADI, under the assumption that the additive occurs evenly distributed in the whole diet of a child. This concentration is called the primary ceiling. To obtain the technological effect, however, higher concentrations may be needed, and to accomodate this the ceiling may have to be raised. This can be done if the use of the additive can be excluded from or reserved for part of the diet. A safety factor of 100-fold is commonly applied to animal data to derive the acceptable daily intake (ADI) of food additives; other factors have been used in some cases and higher values are used more frequently for determining the tolerable daily intake (TDI) of environmental chemicals. The 100-fold factor is considered to represent the product of a 10-fold factor to allow for species differences between the test animal and humans and a 10-fold factor to allow for inter-individual differences. A scheme is proposed whereby data relevant to the safety assessment of a compound, e.g. species differences in toxicokinetics, can contribute quantitatively to the safety factor and therefore to the ADI or TDI. For this to be possible, it is necessary to subdivide each of the 10-fold factors into two separate factors to allow for differences in toxicokinetics and toxicodynamics. For any compound, data on one particular aspect may be used to derive a specific data-derived factor for that aspect. The overall safety factor will then be calculated as the product of the known data-derived factor(s) and default values for the remaining unknown factors. In this way the derivation of the safety factor would be clearly defined and the potential impact of additional data on other aspects identified. Additional safety factors (over and above the 100-fold or overall data-derived factor) are also proposed to allow for the nature or severity of the toxicity and the adequacy of the database. These factors are consistent with previous evaluations and will allow the logical derivation of factors greater than either 100 or the appropriate data-derived factor. These additional factors will be of greatest value in the derivation of safety factors for the calculation of the TDIs of environmental contaminants but may also be applied if necessary to the safety assessment of food additives. In such cases the rationale and logic for a safety factor in excess of 100 will be clearly defined.
