Assessment of mycotoxin contamination in cereal-based baby foods destined for infant consumption in Brazil

The presence of mycotoxins in cereal-based baby foods is undesirable, especially because infants are considered more vulnerable to toxin exposure than adults. In this context, this study evaluated the occurrence of multiple mycotoxins in 60 samples of cereal-based baby foods from Brazil and assessed the risk of the consumption of these products by children. Aflatoxins B1 and B2 (AFB1, AFB2), deoxynivalenol (DON), 3-acetyl deoxynivalenol (3-ADON), 15-acetyl deoxynivalenol (15-ADON) and zearalenone (ZEN) were evaluated by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results revealed that 98.3% of the samples were contaminated by at least one mycotoxin, with 80% of them demonstrating co-contamination. DON was detected in 80% of the samples, followed by 15-ADON (71.7%), 3-ADON (65%), ZEN (56.7%) and AFB1 (5%), with none of the samples contaminated by AFB2. The maximum concentrations found were 75.6 μg/kg for DON, 18.9 μg/kg for ZEN, 9.6 μg/kg for 15-ADON, 3.5 μg/kg for AFB1 and 2.8 μg/kg for 3-ADON. The occurrence of AFB1 was low, however, some products exceeded the limits established by the current regulations. Although the estimated daily intake (EDI) of DON, 3-ADON, 15-ADON and ZEN were below the safety values currently established, the margin of exposure (MOE) values for AFB1 indicate a concern for public health.

Development and Validation of a modified QuEChERS coupled to Liquid Chromatography-Tandem Mass Spectrometry for the Rapid and Accurate Determination of Acrylamide in Cereal-Based Baby Foods.

With the widespread consumption of cereal-based baby food by children, acrylamide contamination is a prevalent risk that may have carcinogenic consequences. This study aims to develop and validate a modified QuEChERS protocol without solvent exchange, followed by rapid separation and accurate determination of acrylamide in cereal-based baby foods using RP-LC-MS/MS. Samples were extracted using a modified AOAC QuEChERS version and cleaned up with basic alumina. Separation was performed on the Phenomenex® Kinetex C18 column (100 Å × 3.5µm × 4.6 mm × 150 mm) using a gradient elution program with a mobile phase of 10-mM ammonium formate/methanol. Determinations were conducted by ESI-MS/MS in positive ion mode. Basic alumina yielded clean extracts, resulting in acceptable recovery percentages and a tolerable ME < 5%. This has allowed extraction without a solvent exchange step. Efficient separation was achieved at a tR of 3.39 ± 0.05 employing an RP-C18 column with core-shell properties in a relatively short analysis run time of only 5 min. Trueness, precision, LOD, LOQ, linearity range, and R2 results were 92.5-104.6%, RSD≤12.2%, 5 µg/kg, 20 µg/kg, 4.0-1000.0 µg/kg, and > 0.9999, respectively. The test method applicability was demonstrated by proficiency testing and 50 real samples of cereal-based baby foods. Most of the tested samples were in violation of acrylamide's established EU benchmark (40 µg/kg). Acetate-buffered QuEChERS in conjunction with optimized amounts of basic alumina was confirmed as a superior driving approach for optimal method performances. Successful selection of the RP-C18 column is the proper means toward selective separation for acrylamide at a relatively short analysis run time. The modified AOAC QuEChERS with a d-SPE of basic alumina assisted in reducing the ME to tolerable levels while maintaining acceptable method performance. The RP-C18 column of core-shell properties enabled a rapid and accurate acrylamide determination.

Detection and quantification of zearalenone and its modified forms in enzymatically treated oat and wheat flour

An analytical method for the analysis of the mycotoxin zearalenone (ZEN) and its modified forms was developed. Sample preparation was performed based on a modified QuEChERS method combined with liquid chromatography coupled to a triple quadrupole mass spectrometry detection. The method was tested for linearity, precision, limits of detection and quantification and recoveries. The evaluation of the above-mentioned parameters was performed on oat flour. The method was applied to oat and wheat flours that were submitted to an amylolytic treatment (α-amylase and amyloglucosidase), similar to the one used in the cereal-based baby food production process. A decrease in β-zearalenol (β-ZEL) and β-ZEL-14-sulfate of approximately 40% after 90 min incubation was observed, the other analytes did not show any significant changes. To our knowledge, this is the first method that approaches the identification and assessment of ZEN-sulfate derivates in a cereal matrix.

Selective Accelerated Solvent Extraction for Multi-residue Analysis of Organophosphate Esters in Cereal-Based Baby Food

Selective Accelerated Solvent Extraction for Multi-residue Analysis of Organophosphate Esters in Cereal-Based Baby Food

Global arsenic dilemma and sustainability

Arsenic (As) is one of the most prolific natural contaminants in water resources, and hence, it has been recognized as an emerging global problem. Arsenic exposure through food exports and imports, such as As-contaminated rice and cereal-based baby food, is a potential risk worldwide. However, ensuring As-safe drinking water and food for the globe is still not stated explicitly as a right neither in the United Nations' Universal Declaration of Human Rights and the 2030 Sustainable Development Goals (SDGs) nor the global UNESCO priorities. Despite these omissions, addressing As contamination is crucial to ensure and achieve many of the declared human rights, SDGs, and global UNESCO priorities. An international platform for sharing knowledge, experience, and resources through an integrated global network of scientists, professionals, and early career researchers on multidisciplinary aspects of As research can act as an umbrella covering the activities of UN, UNESCO, and other UN organizations. This can deal with the mitigation of As contamination, thus contributing to global economic development and human health. This article provides a perspective on the global As problem for sustainable As mitigation on a global scale by 2030.

Measurement of Polycyclic Aromatic Hydrocarbons in Baby Food Samples in Tehran, Iran With Magnetic-Solid-Phase-Extraction and Gas-Chromatography/Mass-Spectrometry Method: A Health Risk Assessment.

Baby food is one of the most sensitive foods available, which is closely monitored for carcinogens. In this study, 16 Polycyclic Aromatic Hydrocarbon (PAH) compounds were evaluated by using the method of magnetic-solid-phase-extraction and gas-chromatography/mass-spectrometry (MSPE/GC-MS). The recovery, limit of detection (LOD), and limit of quantification (LOQ) of PAH compounds were 93.4–101.6%, 0.06–1.12, and 0.18–3.38 μg/kg, respectively. The results indicated the mean of total PAHs in all samples was 3.73 ± 0.8 μg/kg, and the mean of Benzo[a]pyrene (BaP) was 0.29 ± 0.14 μg/kg that were lower than the USA-Environmental Protection Agency (USEPA) standard level (1 μg/kg, BaP in baby foods). In addition, our results showed that mixed five cereal-based baby food had a maximum mean of ΣPAHs (5.06 ± 0.68 μg/kg) and mixed wheat and date-based baby food had a minimum mean of ΣPAHs (3.03 ± 0.41 μg/kg). The carcinogenic risk due to PAH in the tested baby foods sold in Iran was adequately low, and all examined products were safe for consumers. Therefore, it can be said that the consumption of baby foods does not pose a threat to consumers.

A Useful Method with Appropriate Recovery and High Accuracy in Simultaneous Analysis of 12 Polychlorinated Biphenyls in Cereal-Based Baby Foods Using Gas Chromatography-Electron Capture Detector

A Useful Method with Appropriate Recovery and High Accuracy in Simultaneous Analysis of 12 Polychlorinated Biphenyls in Cereal-Based Baby Foods Using Gas Chromatography-Electron Capture Detector

The Investigation of Mycotoxins and Enterobacteriaceae of Cereal-Based Baby Foods Marketed in Turkey.

In this study, a total of 85 cereal-based baby foods with or without milk (four different brands; A, B, C, and D) collected from Ankara local markets, Turkey were analyzed for mycotoxins, total aerobic mesophilic bacteria (TAMB), and Enterobacteriaceae contamination. Baby foods were analyzed for 12 toxicological important mycotoxins such as aflatoxin B1, B2, G1, and G2; fumonisin B1 and B2; ochratoxin A; sterigmatocystin (STE); deoxynivalenol (DON); zearalenone (ZON); and T-2 toxin and HT-2 toxin by LC-MS/MS multi-mycotoxin method. In addition to these mycotoxins, the presence of aflatoxin M1 (AFM1) was investigated in baby foods containing milk. The classical culture method was used for microbiological analysis. Consequently, at least one mycotoxin was detected in 69.41% of the total samples. The most frequently detected mycotoxins were STE (34.12%) and HT-2 (34.12%). However, AFM1 was not detected in any of the baby foods containing milk. Also, TAMB and Enterobacteriaceae were isolated from 30.59% and 10.59% of samples, respectively. As a result, it was determined that the mycotoxin levels in the analyzed samples were in accordance with the mycotoxin levels specified in the Turkish Food Codex.

Natural Occurrence of Deoxynivalenol in Cereal-Based Baby Foods for Infants from Western Poland.

The study examined 110 samples of baby products based on rice, wheat, maize and multi-grains available on the western Polish market in order to detect the level of deoxynivalenol (DON) by means of HPLC (high-performance liquid chromatography) with a fluorescence detector (HPLC-FLD). DON was detected in 9.09% of the infant food samples, with an average and maximum level of 107.8 ± 30 and 148 μg/kg, respectively. The highest concentration of DON was detected in food for infants: wheat-based (mean 121 ± 7.07, 4.8%), multi-grain (mean 118 ± 5.65, 4.25%) and maize-based (mean 100 ± 37.96; 35.30%). No high DON content and high estimated daily intake were observed in the analyzed products. However, in order to minimize the harmfulness associated with the presence of DON in food for infants and young children, a risk assessment should be performed based on the monitoring results.

Assessment of Benefits and Risks of Probiotics in Processed Cereal-based Baby Foods Lactobacillus Paracasei ssp. Paracasei F19

The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of Lactobacillus paracasei ssp. paracasei F19 (F19) in processed cerealbased baby foods intended for small children 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search. &#x0D; &#x0D; A notification regarding two products of processed cereal-based baby foods (hereafter called cereals), intended for small children and supplemented with the bacterium F19 initiated this work.&#x0D; &#x0D; A daily supply of a monoculture of a particular bacterial strain in large quantities to an age group without a fully established intestinal flora, may have unknown adverse effects. There are however, to our knowledge, no studies investigating possible short or long term adverse health effects of F19 in processed cereal-based baby food given to children 13 months onwards.&#x0D; &#x0D; The documentation and information provided by the notifier regarding the genetic stability of F19 in the two products during processing and storage, is considered insufficient and does not allow any conclusions to be drawn. &#x0D; &#x0D; Moreover, the documentation obtained is not conclusive regarding the antibiotic resistance pattern of the bacterial strain used in the products in question, as the information on different antibiotics is partly inconsistent. The information about specific localization (chromosomal, plasmid) of the resistance genes is not sufficient. &#x0D; &#x0D; Studies demonstrate that F19, as well as other bacterial strains considered probiotic, is able to “crosstalk” with enterocytes in mice and that the result of the “crosstalk” depends upon the microbiota present. Whether F19 has a similar “crosstalk-profile” in humans is unknown. However, as the strain is originally of human origin, it seems reasonable to assume that such “crosstalk” may occur. Thus, before giving F19 daily for months and years, it seems reasonable to ask for additional molecular and physiological studies to unravel the functional impact of possible changes in genetic expression in children. &#x0D; &#x0D; Lactobacillus infections do occasionally occur, mainly as bacteremia, endocarditis and localized infections (e.g. abscesses, peritonitis, and meningitis) in patients with severe underlying diseases. Most of them are elderly, but children are not excluded. The species most often isolated are L. casei and L. rhamnosus, followed by L. paracasei. &#x0D; &#x0D; The increasing use of immunosuppressive therapy and broad spectrum antibiotics which are ineffective against Lactobacillus, might increase the importance of these bacteria as possible pathogens. In order to be able to draw any conclusions regarding beneficial effects of F19, there is a need for randomized placebo-controlled studies in larger populations and in the relevant age group. &#x0D; &#x0D; According to EFSA, Lactobacillus paracasei ssp. paracasei F19 is sufficiently characterized. The documentation provided is, however, not sufficient to claim positive health effects and thus F19 is not proven to be probiotic. &#x0D; &#x0D; There are no published dose-response studies of F19 in children, neither regarding survival of F19 in the gastrointestinal tract, nor possible negative health effects. Thus the potential for negative health effects as e.g. spreading of antimicrobial resistance or unfavourable impact on the genetic expression in children related to the frequency and/or dose of a monoculture of F19 cannot be assessed.

Assessment of Benefits and Risks of Probiotics in Processed Cerealbased Baby Foods Bifidobacterium Lactis Bb12

The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of B. lactis Bb12 in baby foods focusing on the age groups 4-6 months, 612 months and 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search. &#x0D; &#x0D; An notification for use of processed cereal-based baby foods (from now on called cereals) intended for infants and small children supplemented with the microorganism Bifidobacterium lactis (B. lactis) Bb12 in Norway initiated this work. &#x0D; &#x0D; Studies of potential hazards and positive health effects from cereals containing B. lactis Bb12 intended for infants and young children have not been reported in the available literature. However, reports on safety of and positive health effects from infant and follow on formula supplemented with B. lactis Bb12 are available and have been assessed by VKM. In most of these clinical studies B. lactis Bb12 was administered in combination with other probiotic strains.&#x0D; &#x0D; Clinical studies report no serious adverse events of infant formula supplemented with B. lactis Bb12. The effect of long term daily consumption of such supplemented formula by the actual age groups is not known.&#x0D; &#x0D; A few studies have demonstrated some effect of supplementing baby food with probiotics, including B. lactis Bb12, on diarrhoea and atopic eczema while other studies do not show such effects. Thus, the scientific evidence for a favourable effect of supplementing formula or solid food with B. lactis Bb12, is weak and in some cases lacking. &#x0D; &#x0D; There are no studies demonstrating a positive effect of cereals supplemented with B. lactis Bb12 intended for infants and small children.&#x0D; &#x0D; Several health claims related to probiotics have been assessed by EFSA, including claims on reduction of gastro-intestinal discomfort, normal functioning of the alimentary tract, building of the natural intestinal barrier, improvement of the general immunity, mental and cognitive developments of children and immune system of children during growth. In the opinions so far, EFSA has concluded that a cause and effect relationship has not been established between the consumption of the probiotic containing products and the claimed effect. None of the products assessed so far contained B. lactis Bb12 (1 November 2009).&#x0D; &#x0D; Commercially produced cereals are frequent given to infants and small children in Norway from an early age and this is particularly important for the establishment of the intestinal bacterial flora and the development of the intestinal mucosal immune system. According to the notifier, one portion (25gram) of the cereal powder contains 1 x 109 B. lactis Bb12 in monoculture. Taking into consideration that the daily intake is often greater than one portion of cereals, even in infants below 6 months of age, this would represent a daily intake of 1-2 x 109 cfu B. lactis Bb12 for an infant 4-6 months and even more in infants above 6 months. If a considerable amount of the B. lactis Bb12 survives the transport to the small intestine, it would represent a dominating and monocultural supply, often several times a day, to the small intestine. The immaturity and vulnerability of the intestinal microbiota and the immune system makes the two lowest age groups, 4 – 6 and 6 – 12 months, at the highest risk of unwanted health effects due to the daily intake of probiotics.

A Targeted UHPLC-MS/MS Method Validated for the Quantification of Ergot Alkaloids in Cereal-Based Baby Food from the Belgian Market.

Following pending new legislation in the European Union setting a maximum of 20 ng g−1 for the total sum of ergot alkaloids in dry cereal-based baby food, a new UHPLC-MS/MS method was developed. It is suitable for the quantification of six ergot alkaloids: Ergocornine, ergocristine, ergometrine, ergosine, ergotamine, α-ergocryptine, and their corresponding epimers. The method is able to reliably detect individual ergot alkaloids at a level as low as 0.5 ng g−1. The method uses a modified QuEChERS extraction approach before UHPLC-MS/MS analysis. The method showed good sensitivity, accuracy, and precision. It has been applied to 49 samples from the Belgian market. In 26 samples, not a single ergot alkaloid was detected while in 23 out of 49 samples at least one ergot alkaloid was detected with 2 samples containing 12 ergot alkaloids. Ergometrine was the alkaloid most frequently detected i.e., 16 out of 49 samples. Only one sample, testing positive for all 12 ergot alkaloids, would be non-conforming to the newly proposed Maximum Residue Level (MRL).

Occurrence of Aflatoxins in Commercial Cereal-based Baby Foods in Iran: A Probabilistic Risk Assessment to Health.

The aim of this study was to assess the occurrence of Aflatoxins (AFs) including B1, B2, G1 and G2 in commercial cereal-based baby foods by HPLC-FLD method in Iran and related risk assessment in three baby age groups (6-12, 12-18, and 18-24 months) using Monte Carlo simulation approach. Results showed an occurrence ranging from 20% to 60% for B1, B2, and G2 aflatoxins, while AFG1 was not detected in any assessed samples. Exposure and risk assessment was estimated to be two groups (aflatoxin B1 and total aflatoxins). The highest estimated dietary exposure to both AFB1 and total AFs was estimated for 6-12 months aged babies, representing 5.81 ng/kg BW/day and 8.55 ng/kg BW/day, respectively. Overall, the margin of exposures to AFB1 and total AFs were lower than 10,000 in all age groups, indicating a health concern about AFB1 and total AFs exposure through cereal-based baby food consumption. High cancer risk for high consumers (P95) of baby food was also estimated in all age groups, calling for immediate intervention due to serious claims that AFB1, is a highly carcinogenic component, causes hepatocellular carcinoma. Risk ranking results indicated the presence of AFB1 is classified as high risk for babies who consume cereal-based foods, which demands the attention of risk managers to reduce or eliminate this risk for the most vulnerable sector of society, whose aged <24 months.

Simultaneous Analysis of 10 Priority PAHs in Iranian Sangak Bread Samples by Developing a GC-MS Method.

Human exposure to polycyclic aromatic hydrocarbons (PAHs) is known as a carcinogen risk factor. In this study, a gas chromatography-mass spectrometry (GC-MS) technique combined with the QuEChERS extraction method was developed for concurrent analysis of 10 polycyclic aromatic hydrocarbons (PAHs) in Iranian traditional Sangak bread samples. The method was validated by determining different parameters, including; linearity, accuracy, precision, limit of detection (LOD) and limit of quantitation (LOQ). Calibration curves showed a linear relationship in the concentration range of 10-500 ng/g with a coefficient of determination (R2) ranged between 0.994 and 0.999. The obtained mean recoveries were 92-106% with the relative standard deviations (RSDs) in the range of 3-7% with an acceptable precision (RSD < 20%). The Limit of detections (LODs) for different PAHs were between 0.14-0.78 ng/g, while the limit of quantitation (LOQ) was 0.46-2.60 ng/g. Matrix effect studies showed that the analytes concluded signal suppressions or enhancements. Therefore, spiked calibration curves were used for overcoming this issue. The result of Sangak bread samples analysis using the validated method showed that 9 (19.4%) out of 47 Sangak bread samples were contaminated with phenanthrene (PHE) and anthracene (ANT) at the mean level of 10.08 ± 6.38 ng/g which were higher than the permissible limit of European Commission regulatory control value for BaP (1 μg/kg of wet weight) in processed cereal-based foods and baby foods for infants and young children.

Determination and evaluation of in vitro bioaccessibility of added vitamin C in commercially available fruit-, vegetable-, and cereal-based baby foods.

Knowing the bioaccessibility of vitamin C in foodstuffs produced for infants and young children is necessary to determine their daily vitamin C intake. The purpose of the present study was to investigate the bioaccessibility of vitamin C in fruit-, vegetable-, and cereal-based baby foodstuffs by an in vitro digestion model at varying gastric pHs. The concentrations of measured vitamin C were higher than the declared amounts on their label. The bioaccessibility of vitamin C ranged from 10.4 to 43.4%, and from 0.4 to 19.2% in fruit- and vegetable-based baby foodstuffs (declared vitamin C fortified) at gastric pH 1.5 and 4, respectively. For cereal-based baby foodstuffs, the bioaccessibility ranged from 1.3 to 53.8%, and from 0.3 to 26.3% at gastric pH 1.5 and 4, respectively. As revealed in this research, the bioaccessibility of vitamin C in baby foodstuffs is very low in both gastric pH conditions.

The fate of several trichothecenes and zearalenone during roasting and enzymatic treatment of cereal flour applied in cereal-based infant food production

Cereal-based baby food production process is expected to have an impact on the initial level of Fusarium mycotoxins that can contaminate the raw materials. The aim of the present study was to investigate the changes of some of these toxins during roasting and the treatment with amylolytic enzymes, usually applied during the production process. Three different cereal flours contaminated with Fusarium graminearum were considered (barley, wheat and oat). The results did not show significant changes in the concentration of any of the studied mycotoxins (up to 5% change in deoxynivalenol concentration after the enzymes were added). The acetyl-deoxynivalenol also showed slight modifications as a result of the applied processes, however their statistical significance was not proved. Zearalenone and T-2 and HT-2 toxins remained almost unaltered throughout the study.

Aluminum content and effect of in vitro digestion on bioaccessible fraction in cereal-based baby foods.

The aim of this work was to determine the total concentration and the effect of in vitro digestion on the bioaccessible fraction of aluminum (Al) in 35 different cereal-based baby food samples and estimate the exposure to this element considering the consumption of this product. Total Al content was determined by inductively coupled plasma optical emission spectrometry after oxidative microwave digestion. An in vitro digestion method was applied and optimized to evaluate the bioaccessible fraction. The methods performance was efficient for both approached analysis and presented limits of detection and quantitation of 53μgkg-1 and 89μgkg-1, respectively. Total concentration and bioaccessibility varied according to the product composition (rice, oat, wheat, barley, corn, multicereal and fruit). Multicereals and fruit-based (plum) cereals presented the highest total Al concentrations (8.82mgkg-1 and 7.49mgkg-1, respectively), whilst lower values were observed for corn and rice flour cereals (0.92mgkg-1 and 1.09mgkg-1, respectively). The bioaccessible fraction varied from 1.5% to 10.4% in the evaluated samples. Exposure to Al was estimated and compared with the Provisional Tolerable Weekly Intake (PTWI) of 2mgkg-1 body weight. The results showed that the daily consumption of three portions of cereals contributes up to 10.48% of the PTWI, when considering the total Al concentration reported in this study.

Determination and assessment of the bioaccessibility of vitamins B1, B2, and B3 in commercially available cereal-based baby foods

Vitamins B1, B2, and B3 are important nutritional components of cereal-based baby foods. It is important to know the bioaccessibility of these vitamins for infant and young children's nutrition. The aim of this study was to determine and evaluate the bioaccessibility of vitamins B1, B2, and B3 in cereal-based baby foods in different gastric pHs using an in vitro digestive system. The amount of vitamins B1 (thiamine), B2 (riboflavin), and B3 (nicotinic acid and nicotinamide) in 13 cereal-based baby foods were determined using high performance liquid chromatography (HPLC). When compared with the declarations on the label, the measured vitamin B1, B2, and B3 amounts ranged from 105% to 246%, 107% to 207%, and 115% to 170% of the listed amount in cereal-based baby foods, respectively. The average bioaccessibility of thiamine, riboflavin, nicotinic acid, and nicotinamide in cereal-based baby foods in gastric pH 1.5 were 81%, 79%, 39%, and 51%, respectively. When the gastric pH increased to 4, the average bioaccessibility was 65%, 67%, 33%, and 41%, respectively. It is thought that the bioaccessibility of vitamins B1, B2, and B3 is significantly influenced by stability, temperature, pH of the gastrointestinal tract, dietary fiber content, as well as bonds with polysaccharides and polypeptides. These results indicate that the bioaccessibility of these water-soluble vitamins may be low in vivo.

Mycotoxin contamination in cereal-based baby foods

Compared to adults, children and especially infants, have a markedly different physiology. Mainly due to metabolic rates and lower body weight, infants are recognized as a potentially vulnerable subgroup with respect to consumption of mycotoxins. In this review, analysis of the main mycotoxins occurring in food intended for children, such as aflatoxins, ochratoxin A, Fusarium toxins and Alternaria toxins, is presented. Aspects regarding general mechanisms of toxicity, tolerable daily intake and regulations are shown. Additionally, occurrence of mycotoxins in cereal-based baby foods during the last 15 years is are also discussed.

Determination and evaluation of in vitro bioaccessibility of the pyridoxal, pyridoxine, and pyridoxamine forms of vitamin B6 in cereal-based baby foods

The bioavailability of the pyridoxal (PL), pyridoxine (PN), and pyridoxamine (PM) forms of vitamin B6 is different, considering that their bioaccessibility in baby foods is important for infant and young children’s nutrition. The aim of this study was to determine and evaluate the bioaccessibility of the PL, PN, and PM forms of vitamin B6 in cereal-based baby foods an in vitro digestive system. In this study, the PL, PN, and PM forms of vitamin B6 were determined using HPLC in 13 cereal-based baby foods. The average bioaccessibility of the PL, PN, and PM forms in gastric pH 1.5 were 53%, 76%, and 50%, respectively. When the gastric pH was 4, the average bioaccessibility of PL, PN, and PM were 38%, 67%, and 36%, respectively. As observed in this study, the bioaccessibility of the PL, PN, and PM forms of vitamin B6 in baby foods is lower in both gastric pHs.
