This hyperglycaemic action has been confirmed in rats, but a hypoglycaemic effect has been reported in mice (Fernandes et al., 2002). The 95th percentile ranged from 0.01 mg/kg bw per day in the elderly to 0.65 mg/kg bw per day in toddlers. In his 2009 review, Scotter (2009) summarised the key aspects of the structural determination of bixin and norbixin, paying special attention to cis–trans isomerisation and how this is linked with their chemical structure, spectroscopic properties, and oxidative, thermal and photochemical stability. Sprague–Dawley rats (108 males and 108 females, strain Crl:CD(SD)IGS BR VAF/plus) in the weight range of 180–240 g were used. Data on the non‐colouring fraction of this product have been requested in 2008. Some toxicological effects were observed. Mitochondrial damage in the liver and pancreas was produced with the purified material. (1991) purified the extract by column chromatography and monitored the biological activity using the oral glucose tolerance test in anaesthetised mongrel dogs. Submitted on 29 November 2013. While there is no standard system for coding on canned foods, many companies use similar codes to track their products. In the non‐brand‐loyal scenario, mean exposure ranged from 0.001 mg/kg bw per day in adults to 0.08 mg/kg bw per day in toddlers. Although the results obtained were clearly negative, the Panel noted that this kind of study only detects effects on chromosome integrity and segregation, but not gene mutations which were the prevailing effect detected in vitro. Find out what is the full meaning of E160B on! However, a set of unpublished properly performed in vitro and in vivo genotoxicity studies on Annatto B, E, and F were also available to the Panel for evaluation. Annatto B was a blend of two representative commercial products and complied with the JECFA specification for the solvent‐extracted bixin, with the exception of the purity criteria for acetone (50.9 mg/kg instead of ≤ 30 mg/kg) and methanol (645 mg/kg instead of ≤ 50 mg/kg). unripened cheese). These products will become yellow or orange yellow when reconstituted (Doc. Competent authorities in the European countries provide EFSA with food consumption data at the level of the individual consumer from the most recent national dietary survey in their country (cf. Australian Journal of Nutrition and Dietetics 1996;53(3): page 92. CI 75120. (pKM101), Norbixin Standard. FDE (FoodDrinkEurope), 2013. Furthermore, at the request of the European Commission, the present opinion included the evaluation of the safety of five other annatto extracts categorised as bixin‐ or norbixin‐based, following the request of the NATCOL/Annatto Interest Group for authorisation of these extracts, with the view to replace the currently authorised food additive (E 160b). In humans, there are a limited number of studies that reported that the annatto extracts might be a possible cause of angiooedema, urticaria or eczema. Each of these additives is given its own unique number, making it easier for manufacturers to list which ones are included in foods. Dietary surveys with only 1 day per subject were excluded as they are considered as not adequate to assess repeated exposure. Given: (a) that read‐across among the five bixin‐ and norbixin‐based annatto extracts was feasible; (b) the availability of adequate 90‐day toxicity studies with Annatto B, C, E and F; (c) the absence of concern for mutagenicity, carcinogenicity, reproductive and developmental toxicity of Annatto B, C, F and G, whereas the mutagenicity of Annatto E is equivocal, the Panel concluded that the safety of the currently authorised solvent‐extracted bixin and norbixin (E 160b(i)), alkali‐extracted annatto (E 160b(ii)) and oil‐extracted annatto (E 160b(iii)), with the specifications defined in Commission Regulation (EU) No 231/2012, could not be assessed due to the lack of data, both in terms of identification and toxicological studies; solvent‐extracted bixin (Annatto B), solvent‐extracted norbixin (Annatto C), alkali‐processed, acid‐precipitated norbixin (Annatto F) and alkali‐processed, not acid‐precipitated norbixin (Annatto G and its norbixin salts) should comply with the specifications as recommended by the Panel. A-1. E numbers ("E" stands for "Europe") are codes for substances used as food additives for use within the European Union (EU) and European Free Trade Association (EFTA). Thus, the results of this study could not be considered for risk assessment. For example, the increase in liver weight was most marked with the alkali‐processed, acid‐precipitated norbixin (Annatto F), less with the aqueous‐processed bixin (Annatto E) and hardly present with the solvent‐extracted bixin (Annatto B), whereas the response of the aqueous‐processed bixin (Annatto E) was greater than that of the solvent‐extracted bixin (Annatto B). Additional studies, preferably with pure bixin and norbixin, on their metabolism in rats and humans may reduce the uncertainty. Decreased body weight gain was observed in males, but there was no effect on either food intake or food conversion efficiency. They revealed that the active constituent responsible for the hyperglycaemic action was the methyl ester trans‐bixin (MW 394). ICGA (International Chewing Gum Association), 2013. The exposure per food category was subsequently added to derive an individual total exposure per day. Evaluation of certain food additives and contaminants, Toxicological evaluation of certain food additives. At the end of the treatment period, animals were killed by carbon dioxide inhalation and all animals were subjected to a detailed necropsy. E160b: Annatto, Bixin, Norbixin. In rats dosed with OSB, the blood level was 62 mg/100 mL after 3 h and 19 mg/100 mL after 24 h. Thus, OSB was metabolised less rapidly than WSA, presumably because the OSB pigments would need to be metabolised to water‐soluble pigments, similar to those of WSA, before being metabolised further. (1959), no adverse effect on reproduction or development were to be expected from the five annatto extracts described in the present opinion, which all show higher concentrations of bixin or norbixin. Cultures were treated for 6 h in the presence, and 6 or 22 h in the absence of S9 mix. Under this assumption, the applicant concluded that the findings of the developmental toxicity study with the aqueous‐processed bixin (Annatto E) performed by Paumgartten et al. Rats received Annatto E by dietary administration at levels of 3,000, 10,000 or 30,000 mg/kg diet for 13 weeks. Method recoveries were comprised between 99% and 102%; the LOQ was 0.5 mg/kg. The applicant assumed that the extraction with chloroform is comparable with the organic solvent extraction technique used for the solvent‐extracted bixin (Annatto B). Most auto repairs shops charge between $75 and $150 per hour. The Panel noted that the material tested was considered not representative of the annatto extracts used as food additive. The studies with the solvent‐extracted bixin (Annatto B) revealed an effect on the kidney, with raised protein concentrations noted in urine samples obtained from males receiving 50,000 mg/kg diet. Lycopene. Scotter (1998) analysed samples of commercial annatto formulations for bixin or norbixin by applying a developed method utilising high‐performance liquid chromatography (HPLC) and photodiode array detection (HPLC‐PDA); results were compared with those obtained from using UV‐visible spectrophotometric methods. Available online: The test material complied with the specifications for alkali‐processed, not acid‐precipitated norbixin (Annatto G) (actual content of the tested batch: 17.1%). NOAEL: no‐observed‐adverse‐effect‐level; NA: not applicable; NR: not reported. Please check your email for instructions on resetting your password. Full histopathological examination of all tissues was carried out on all animals in Groups 1 and 4, and of the kidneys, liver and lungs of all other groups, and all abnormal appearing tissues observed at necropsy. provided to EFSA n.3), several systematic reviews on annatto have been published (Lim, 2012; Ulbricht et al., 2012; Vilar et al., 2014). The NOAEL was determined by the study authors to be 86 mg/kg bw per day (equivalent to 33 mg norbixin/kg bw per day) based on the changes in renal function observed at the two highest dose levels. When compared with the controls, there was a clear effect of treatment on food intake in treated males. (1987) investigated and demonstrated the hypoglycaemic activity of chloroform extract residues of B. orellana dissolved in either oil (peanut or olive) or 95% ethanol in the dog. Pronounced ask-ee, ASCII is the acronym for the American Standard Code for Information Interchange.It is a code for representing 128 English characters as numbers, with each letter assigned a number from 0 to 127. laying down specifications for food additives), three different annatto extracts are described: (i) solvent‐extracted bixin and norbixin (E 160b(i)); (ii) alkali‐extracted annatto (E 160b(ii)); and (iii) oil‐extracted annatto (E 160b(iii)). Based on the origin of the annatto extracts (i.e. The regulatory maximum level exposure assessment scenario for annatto (E 160b) is based on the MPLs as set in Annex II to Regulation (EC) No 1333/2008 and listed in Table 6. Exposure estimates for bixin were below the ADI for all population groups and for all refined exposure scenarios, including for the extension of use. The three annatto extracts (Annatto B, Annatto E and Annatto F) were administered by gavage to five male and five female mice at three exposure levels (the maximum tolerated dose and two lower ones) twice, 24 h apart, and mice sacrificed 24 h after the last treatment. and you may need to create a new Wiley Online Library account. Preliminary testing confirmed the homogeneity and stability of the Annatto C in the powder diet MF. Additionally, analytical results from the Member States were collected through the EFSA call for concentration data. Food was withheld overnight, and restored 2 h after dosing; water was available ad libitum throughout the study. LD50 values amounted to 700 mg/kg bw for a water‐soluble annatto extract (no further details given) upon intraperitoneal (i.p.) The annatto pigments in rat's blood were determined 3 h and 24 h after treatment. Since the test material contained 38.4% norbixin, these dosages corresponded to 30, 92 and 289 mg norbixin/kg bw per day in males, and 33, 106 and 313 mg norbixin/kg bw per day in females. These E-Numbers have been formulated by the European Economic Community (EEC) and are universally adopted by the food industry worldwide. provided to EFSA n. 3). E codes are codes sometimes found on food labels in the European Union (GB, France, Germany, Spain, Italy, Portugal, etc.) Origin: Sodium salt of inosinic acid (), a natural acid, that is mainly present in animals.Commercially prepared from meat or fish (sardines). Agner et al. In all studies, norbixin was the major component present in the plasma and urine, even following administration of bixin‐based extracts, most likely derived from both the norbixin present in the extract, as well as metabolism of bixin to norbixin. There was no increase in embryolethality and no reduction in fetal or placental weight. The 95th percentile exposure ranged from 0.01 mg/kg bw per day in the elderly to 0.40 mg/kg bw per day in toddlers. Origin: Natural colour isolated from the seeds of the annatto tree (Bixa orellana ).Annatto is the name of the crude extract, whereas bixin is the fat-soluble colour and norbixin the water-soluble colour Volume 1–3, Pharmacokinetic studies with annatto blends B, E and F in the rat, Annatto type B. Micronucleus test in bone marrow of CD‐1 mice. A common chemical name for cis‐bixin is methyl (9′‐cis)‐hydrogen‐6,6′‐diapo‐ψ,ψ‐carotenedioate; its molecular formula and molecular weight are C25H30O4 and 394.50 g/mol. The composition of the alkali‐processed, not acid‐precipitated norbixin (Annatto G) is similar to composition of the alkali‐processed, acid‐precipitated norbixin (Annatto F), when compared on a calculated dry weight basis, as the liquid Annatto G contains 90% water. In the non‐brand‐loyal scenario, mean exposure ranged from 0.003 mg/kg bw per day for infants to 0.18 mg/kg bw per day for toddlers. At the end of the treatment period, no increase in DNA damage was observed by the comet assay in the liver of treated rats compared to control animals fed with standard diet, and no modifying effect on DNA damage induced by diethylnitrosamine (20 mg/kg bw, i.p. The rec assay for DNA damage in the bacterium Bacillus subtilis was conducted with a water‐soluble annatto extract, but no experimental details were given. Reduced food conversion efficiency values were noted in the Group 4 males in weeks 3 and 4 (30,000 mg/kg diet), but these were not affected in females. Biological data on the non‐pigment part of Annatto E may be relevant to the non‐pigment parts of Annatto F and G, with the exception of tocotrienols, which should not be present anymore in an active form in both products after alkaline treatment. The samples differed significantly in their all‐trans‐ and di‐cis‐norbixin isomer contents, which was indicative of their respective production histories. The annatto extract (Annatto F) did not induce any increase in the incidence of externally visible, visceral or skeletal abnormalities in the exposed offspring at doses up to 160 mg/kg bw per day. All substances were dissolved in DMSO and tested at 125, 250, 500, 1,000, 2,500 and 5,000 μg/plate using triplicate plates. Studies have been reported in the literature in the mouse, rat and dog, and the results for all the three species were discussed in previous evaluations of the SCF and JECFA. At the end of the main experiment (24 h), the rats were anaesthetised with isoflurane and sacrificed. With the alkali‐processed, acid‐precipitated norbixin (Annatto F), haematological changes were also observed. The body weight gains of treated animals were not significantly affected by the treatment in any of the groups. The authors noted that similar conversion occurred with other carotenoids, such as β‐carotene and lycopene. Three years later, JECFA re‐considered at its 67th meeting its opinion and agreed that the observed toxicological effects were rather attributed to bixin and norbixin than to the non‐colouring material (JECFA, 2007). Although the database was limited, the overall pattern of absorption and metabolism appeared to be similar in the rat and humans and, therefore, the Panel considered the rat an adequate model for assessing the toxicity of annatto extracts in humans. In the review by Scotter (2009), several other methods are also mentioned. The increase in plasma norbixin suggested a conversion of bixin to norbixin. for scientific data on food additives, including present use and use patterns (i.e. Similarly, in life‐time studies (Van Esch et al., 1959), no significant toxicity was reported when animals were fed with either the fat‐soluble or the water‐soluble annatto extract containing between 0.2% and 2.6% bixin (no further details given in this limitedly reported study). For the exposure assessment, the Panel considered only analytical data resulting from authorised uses at levels not exceeding the MPLs. In 2006, JECFA agreed upon two separate ADIs for bixin‐ and norbixin‐containing annatto extracts: an ADI of 12 mg/kg bw for bixin (92% bixin pure) and a group ADI of 0.6 mg/kg bw for norbixin (91.6% norbixin pure) and its sodium and potassium salts (JECFA, 2007). Mechanical abrasion using food grade vegetable oil … Is vegetable annatto butter color cancerogenic? Subsequently, De Oliveira et al. Some information became available from industry (i.e. Orange and/or yellow staining was seen in all animals dosed at 9,000 mg/kg diet and in many animals dosed at 3,000 mg/kg diet. At the end of the 90‐day toxicity studies (Section on the solvent‐extracted bixin (Annatto B), aqueous‐processed bixin (Annatto E) and alkali‐processed, acid‐precipitated norbixin (Annatto F) in rats, liver samples were taken from 10 males and 10 females. Annatto can cause allergies and eczema. However, the maximum limits for the impurities of toxic elements (arsenic, lead, mercury) should be revised in order to ascertain that the annatto extracts as food additives will not be a significant source of exposure to these toxic elements in foods. , Kay and Calandra ( 1961b ) administered aqueous annatto extracts used as liquid color, the requested...
