Mineral profile of Spanish commercial baby food

A Descriptive Study of Spanish and Ecuadorian Commercial Infant Cereals: Are They in Line with Current Recommendations?

Cereals are an important source of nutrients, especially used in complementary feeding. The objective of this study is to review the nutritional composition of cereal-based foods for infants from 4 months and toddlers that are offered in Spain and Ecuador, countries selected because of the opportunity to work in them, and due to their socio-economic differences (industrialized and developing countries, respectively). The number of these products was 105 cereals in Spain and 22 in Ecuador. The products were classified as gluten-free cereals, five cereals, eight cereals, multigrain cereals, and cookies. A 25 g serving was used to determine the percentage in which the samples analyzed can cover the Reference Nutrient Intake (RNI) for micronutrients in infants from 7 months and toddlers according to the European Food Safety Authority (EFSA). Nutritional information per 100 g of dry product was collected according to medium, minimum, and maximum units, and nutrient density was calculated. The age range in which these products are recommended is different in both countries. The nutritional composition presents some differences; Spanish cereals show a lower content of sodium, added sugars, hydrolyzed cereals, and maltodextrin than Ecuadorian cereals. Commercialized cereals could contribute to satisfying the nutritional needs of infants and toddlers; however, they can also be a source of non-recommended components.

Diet Diversity During Infancy and the Prevalence of Sensitization and Allergy in Children up to 3 Years of Age in the Kujawsko-Pomorskie Voivodeship, Poland

The study examines the influence of a diversified diet, changes in the consistency of introduced foods, and the method of meal preparation during infancy on the development of sensitization and/or allergy in toddlers. Introducing more product groups into the diet reduced the risk of allergy at 6 months of age (adjusted odds ratio [aOR] = 0.17; 95% confidence interval [CI] 0.04-0.71; P = 0.015) and at 12 months (aOR = 0.14; 95% CI 0.03-0.57; P = 0.006). Children with allergy and/or sensitization had been introduced to fewer product groups at 6 months (P = 0.003; P < 0.001; P = 0.008) and at 12 months (P = 0.001, P < 0.001; P = 0.001) compared with those without allergy and/or sensitization. Children with allergy and/or sensitization were fed ready-made, ie, purchased, products significantly more often than self-prepared foods compared with children without allergy and/or sensitization (P = 0.001; P = 0.006). Allergic and/or sensitized children tended to be switched to solids later (11 vs 10 months, P = 0.041; P = 0.037) (12 vs 10 months, P = 0.013) than children without sensitization and/or allergy. The earlier introduction of a varied diet reduced the risk of allergy and/or sensitization. Delaying the introduction of solid foods and using ready-made products instead of self-prepared ones increases the risk of allergy in toddlers.

Evaluation of the quality and safety of commercial complementary foods: Implications for nutrient adequacy and conformance with national and international standards

Optimal nutrition in early childhood increases growth and development while preventing morbidity and mortality in later life. This study focused on the quality and safety of 32 commercially produced complementary foods collected from supermarkets in Addis Ababa, Ethiopia. The proximate composition (moisture, protein, fat, crude fibre, and ash); and the mineral profile (calcium, iron, zinc, manganese, and magnesium) were determined using the AOAC method. The determination of antinutritional factors (Condensed tannin and oxalate) was done using a UV spectrophotometer. A rapid visco analyzer was used to measure the rheological property. The microbial load of commercially produced complimentary foods was identified using aerobic colony counts for mold and yeast. Labeling practice was evaluated using the WHO and Ethiopian standard tools. The results of proximate compositions were: protein (0.92-18.16 g/100g), fat (0.63-6.44 g/100g), crude fiber (1.04-13.2 g/100g), energy (410-337 kcal/100g), moisture (0.03-17 g/100g), and ash (0.60-4.67 g/100g). The protein and fat content of all the products is below international standards. Only three products met the standards for energy. Moisture and ash contents partially met the requirement, while all of the carbohydrate contents of the products fell under the specified standard. The lowest and highest mineral contents of the products were: Fe (1.38 to 15.10 mg/100g), Zn (0.64 to 6.78 mg/100g), Ca (30.55 to 364.45 mg/100g), Mg (1.2 to 34.2 mg/100g), and Mn (0.80 to 32 mg/100g). Based on these, 21.5% of the foods met the Fe standard, and 31.5% didn't meet the Zn standard. The Ca and Mg of all the products met the requirement. Except for one product, all met standards. The highest and lowest results for the tannin and oxalate content of the products were 49.20 to 90.09 mg/100g and 0.47 to 30.10 mg/100g, respectively and this shows that the products are below the permissible range for tannin and oxalate. The counts of yeast and mold were 0.00-2.95 log10 cfu/g and 0.00-2.91 log10 cfu/g, respectively. Only one product fell below the standard for yeast count, and none of the products showed a mold count that exceeded the standard. The final viscosity was 63.5-3476 RVU, and only 31.25% of the samples fell under the permissible peak viscosity range, of 83-250 RVU. Thus, regular monitoring of the raw material and processing trends and the inclusion of animal sources in the raw material are suggested for having well-enriched complementary foods. Regulatory bodies should also conduct frequent market surveillance to safeguard the health of the consumer.

Nutritional aspects of commercial infant and toddler food products sold in Turkey

Background: In recent years, there has been an increase in the variety and consumption of commercial infant and toddler food products. Aim: The aim of this study is to evaluate the nutritional profiles of commercial infant and toddler food products sold in Turkey. Methods: A cross-sectional survey of the nutritional composition of products available at in-store and online supermarkets in Turkey was derived from the nutritional information panel on the product label or information provided on manufacturer websites in March 2023. The targeted age group, package type, serving size, ingredients list, and nutrition information (energy [kcal], protein [g], total fat [g], carbohydrate [g], dietary fiber [g], total sugar [g], and sodium [mg] per 100 g) were recorded. Results: Of the 189 products identified, more than 90% (n = 47) of the first foods were fruit-based, while 2% (n = 4) contained only vegetables. Almost half of the products (n = 89, 49%) contained added sugar or sweeteners, 41 (22%) had added sugar, and 1 in 3 products (n = 68, 36%) had sugar from fruit-based sources. One in 10 products (n = 18, 9.5%) contained added salt while 40% of the products (n = 76) were above the WHO Europe sodium standards. Almost half of the products (n = 6, 46%) targeting the 12 months older age group were pureed foods using squeeze pouch packaging. Conclusions: The majority of commercial infant and toddler food products did not adhere to nutrition guidelines. There is a need for stronger composition standards for commercial infant and toddler food products by reducing sugar and sodium content, reducing the use of fruits and sweet vegetables, and increasing the variety of products containing different types of vegetables.

Evaluation of Selected Antioxidant Parameters in Ready-to-Eat Food for Infants and Young Children

Infants and young children have diverse dietary needs, so conducting a detailed analysis of the food they consume in terms of antioxidant activity and the content of antioxidant elements is of utmost importance. The aim of the study was to assess the antioxidant properties and the content of Cu (copper), Se (selenium), and Zn (zinc) in baby products. A total of 398 samples of ready-to-eat food consumed by children were tested. To evaluate the antioxidant activity (338 samples, without dairy), the Folin-Ciocalteu method and the 2,2-diphenyl-1-picrylhydrazyl radical scavenging test (DPPH) were employed to determine the total phenolic content (TPC). For the determination of mineral component content (398 samples), atomic absorption spectrometry (AAS) was used to analyze the levels of Cu and Zn, while inductively coupled plasma mass spectrometry (ICP-MS) was utilized for the quantification of Se. Fruit and vegetable mousses exhibited the highest average total phenolic content (TPC) and the highest percentage of free radical scavenging in the DPPH test. In terms of mineral content, the group of dairy products recorded the highest average levels of Cu and Se, while porridges contained the highest content of Zn. Notably, only organic baby food contained significantly more Zn compared to conventional food (12.2 ± 13.9 mg/kg vs. 10.7 ± 14.4 mg/kg). Ready-to-eat products designed for consumption by children provide antioxidant properties, and the presence of Zn, Cu, and Se can contribute to supporting antioxidant processes.

A survey of toxic elements in ready to eat baby foods in the US market 2021

A non-targeted convenience survey was conducted in 2021 to estimate the range of total arsenic (As), cadmium (Cd), total mercury (Hg) and lead (Pb) concentrations in ready-to-eat baby foods. Four hundred samples were purchased both online and in brick-and-mortar retail. Samples included both organic and non-organic products, packaged in glass or plastic jars and foil or plastic pouches. Samples were analysed by acid assisted microwave digestion and ICP-MS with an emphasis on ultra-low detection limits. Limits of quantification were 2.26, 1.31, 0.72, and 3.14 µg/kg (ppb) for As, Cd, Hg and Pb, respectively. The median concentrations of As, Cd, Hg, and Pb in tested products were 2.60, 1.81, 0.09, and 1.38 µg/kg, respectively. Foods containing rice were more likely to contain arsenic. Foods with leafy greens, such as spinach and kale, were more likely to contain cadmium and foods with root vegetables had the highest concentrations of lead.

Comparison of Feeding Practices and Growth of Urbanized African Infants Aged 6-12 Months Old by Maternal HIV Status in Gauteng Province, South Africa

Appropriate feeding practices are protective against malnutrition and poor growth. We compared feeding practices and growth in HIV-exposed-uninfected (HEU) and HIV-unexposed-uninfected (HUU) between 6-12 months of age in urbanized African infants in South Africa. A repeated cross-sectional analysis was used to determine differences in infant feeding practices and anthropometric measures by HIV exposure status at 6, 9, and 12 months in the Siyakhula study. The study included 181 infants (86 HEU; 95 HUU). Breastfeeding rates were lower in HEU vs. HUU infants at 9 (35.6% vs. 57.3%; p = 0.013) and 12 months (24.7% vs. 48.0%; p = 0.005). Introduction to early complementary foods was common (HEU = 16.2 ± 11.0 vs. HUU = 12.8 ± 9.3 weeks; p = 0.118). Lower weight-for-age Z-scores (WAZ) and head circumference-for-age Z-scores (HCZ) were found in HEU infants at birth. At 6 months, WAZ, length-for-age Z-scores (LAZ), HCZ, and mid-upper-arm circumference-for-age Z-scores (MUACAZ) were lower in HEU vs. HUU infants. At 9 months, lower WAZ, LAZ, and MUACAZ were found in HEU vs. HUU infants. At 12 months, lower WAZ, MUACAZ, and weight-for-length Z-scores (-0.2 ± 1.2 vs. 0.2 ± 1.2; p = 0.020) were observed. HEU infants had lower rates of breastfeeding and poorer growth compared to HUU infants. Maternal HIV exposure affects the feeding practices and growth of infants.

Risk Assessment of Metal(Loid)s Exposed to Infants via Consumption of Weaning Foods from Different Supermarkets in Sheffield, UK

Infant complementary foods are readily available in the UK markets and nowadays, weaning mothers prefer feeding their babies with these products due to modern lifestyles. However, there is a dearth of research with respect to the health risk assessment of trace essential and potentially toxic elements in these products. Hence, this research investigated the health risks of trace essential and potentially toxic elements exposed to infants via consumption of these complementary foods during the first 4 to 12 months of life. Levels of trace essential and potentially toxic elements were determined using inductively coupled plasma mass spectrometer, daily intakes were estimated using the Food Agricultural Organization/World Health Organization and manufacturer food consumption regime while the US Environmental Protection Agency guideline was used to estimate target hazard quotient and carcinogenic health risk indices. The levels of the elements in the foods varied and were within the safe limits recommended by food standard agencies. The results also showed that the estimated daily intakes of these elements were below the reference doses stipulated by food regulatory agencies. The target hazard quotients and the total carcinogenic risks of the elements in the infant foods were less than 1 and 1.0E-04, respectively, signifying that the target groups may not experience adverse non-carcinogenic and carcinogenic health effects because of these foods. This study will be quite helpful for weaning mothers, infant food production and processing companies and government officials in taking protective measures for reducing elemental contamination in infants' complementary foods.

In vitro evaluation of the bioaccessibility of antioxidative properties in commercially baby foods

Fruit-vegetable based products are essential for infants as they widely used the first complementary solid foods. This study aimed to investigate the physicochemical properties, the antioxidant capacities, total phenolic content, and bioaccessibility of 24 different commercially fruit-vegetable based complementary foods. To determination of bioaccessibility, samples were processed by an in vitro digestive enzymatic extraction that mimics the conditions in the gastrointestinal tract. Total polyphenol content was analyzed using Folin-Ciocalteu assay, and antioxidant capacities were assessed by CUPRAC and ABTS methods. The total phenol content of the samples ranges from 892.21 to 1729.13 mg GAE mg/100 g. While the antioxidant capacity of the samples averages 256.26 µmol TE mg/100 g according to the ABTS method, they were found 2417.79 µmol TE mg/100 g for CUPRAC method. Also, the bioaccessibility of total phenol content determined 62.72-98.48% of all samples. As a result, antioxidant properties and bioaccessibility of the samples were changed according to the sample content and chemical composition. The use of fruit or fruit juice in the preparation of commercial baby food has improved antioxidant capacity and bioaccessibility, thus increasing the beneficial health effect and nutraceutical properties of the baby meal.

Nutritional Adequacy of Commercial Complementary Cereals in Germany

Commercial cereals are among the first complementary foods fed to infants in Germany and elsewhere. The purpose of this national survey is to describe the nutritional adequacy of commercial complementary cereals. A comprehensive, cross-sectional survey of cereal manufacturer websites (n = 15) was conducted from March to April 2019. Food labels were analyzed for iron, zinc, iodine, sodium, and sugar contents in commercial complementary cereals, and ingredient lists were evaluated for whole grains and added sugars. Preparation instructions were evaluated for the type of liquid recommended for reconstitution. Among 164 commercial complementary cereals, few contain iron (n = 43, 26%), zinc (n = 23, 14%) or iodine (n = 43, 26%). Sodium contents fall within EU thresholds. Most cereals were single grain, containing only wheat (n = 54), with half of the products (n = 86, 52%) containing whole grains. The average carbohydrate content of dry cereals is 69 g/100 g ± 9 g of which 14 ± 15 g is sugar. Preparation instructions for breakfast porridges and cereals recommend formula or toddler milk, while few recommend human milk (n = 13, 18%). Few commercial complementary cereals contain appreciable amounts (at least 15% of daily reference values) of zinc, iron, or iodine. A quarter of cereal carbohydrates are sugar and one-third of the products contain added sugars. Future directives should stipulate minimum micronutrient levels, strictly regulate sugar contents, and include human milk among preparation instructions.

Mineral compositions of infant complementary foods in relation to dietary daily intake and synergistic/antagonistic interrelationships

This study investigated the levels of selected essential elements in a brand of industrially prepared complementary foods in the UK for infants aged 4+, 7+, and 10+ months in order to ascertain their nutritional standards relative to the mineral reference daily intakes and interrelationships. Estimated daily intake of minerals was calculated from elemental contribution from the complementary foods and breast milk. The results showed remarkable significant differences (p < .05) in the concentration levels of the elements in the complementary foods. There were no significant differences (p > .05) between the estimated daily intakes compared to the standard values stipulated by the regulatory bodies. Although, the results showed that specific interrelationships were generally justified by the elemental contents, there were few differences with respect to the overall elemental profile. The results of the study support the recommendation of the use of semi-pureed meals by infants as complementary foods. However, the results of mineral interrelationships implicated imbalances and thus recommend fortification of the infants' complementary foods with iron, calcium, and zinc.

Composition of chemical elements in the edible viscera of Tibetan pigs and its correlation with environment and feed

The main purpose of this research was to evaluate the element distribution in the edible viscera of Tibetan pigs and to clarify its correlation with soils, drinking water and feed. A total of 55 chemical elements were simultaneously quantified. P, K, Na, Mg, Ca, Fe and Zn were the most abundant elements in the analyzed viscera. The general distribution of all element concentrations in the viscera of Tibetan pigs was such that liver > kidney > small intestine > heart = lung = large intestine > stomach. Comparison with national and international allowable limits of toxic elements indicates that consumption of Tibetan pig viscera presents potential health risks. Spearman correlation analysis reveals that significantly (p < 0.0001) positive relationships exist between the element profiles of viscera and drinking water, soils as well as feed. For all edible viscera, the largest values of correlation coefficient were observed to be with corn feed. Our research provides a relatively comprehensive investigation of the elemental composition in Tibetan pig viscera. The correlation data would be helpful for the local farm to reformulate the feed for Tibetan pigs to improve the quality and safety of the viscera.

Nutritional aspects of commercially prepared infant foods in developed countries: a narrative review

Nutritional intake during infancy is a critical aspect of child development and health that is of significant public health concern. Although there is extensive research on breast-feeding and timing of solid food introduction, there is less evidence on types of solid foods fed to infants, specifically commercially prepared infant foods. The consumption of commercially prepared infant foods is very prevalent in many developed countries, exceeding the consumption of homemade foods in some situations. Although these food products may have practical advantages, there are concerns about their nutritional composition, sweet taste, bioavailability of micronutrients, diversity of ingredients and long-term health effects. The extent that the manufacturing, fortification and promotion of these products are regulated by legislation varies between countries and regions. The aim of the present narrative review is to investigate, appraise and summarise these aspects. Overall there are very few studies directly comparing homemade and commercial infant foods and a lack of longitudinal studies to draw firm conclusions on whether commercial infant foods are mostly beneficial or unfavourable to infant health.

Influence of type and shelf-life on two brands complementary food in color, vitamins, and sensory evaluation

The aim of our study was to measure the color by system CIELAB, sensory analysis, and determination of vitamins in children vegetable complementary feeding (carrot, vegetable mix) with the option to extend shelf life from eighteen to twenty-one months. Complementary children food was obtained from private factory in the Czech Republic. In this research there were used only carrot and vegetable mix samples. To determine the color changes by system CIELAB and determination of vitamins, samples of mash were analyzed before filling into jars and sterilization, and then immediately after sterilization. Further analyzes were performed for twenty-one months, with run of every three months (p <0.05). The comparison of color CIELAB parameter L* (lightness) for two process steps: raw mash and sterilized mash; there were significant differences when processing (p <0.0001, r2 = 0.9983). Mainly, the parameter L* (Lightness) showed statistically significant differences in carrot and garden mix (p <0.05). β-carotenes such as provitamin A, is in food of plant origin stable substance in the absence of air. Storing time had significant influence on contain of β-carotenes, the mean content during twenty-one months was 0.862 mg.100g-1 (p <0.05, r2 = 0.2300). There were no significant differences in dark storing (p >0.05, r2 = 0.1097). The sensory evaluation showed statistical differences in all descriptors (color saturation, uniformity of color, consistency and homogeneity) (p <0.05) in course of months of storage time and storage conditions (daylight-dark). The results can be recommended to manufacturers, extending the period of minimum shelf life of the required three months to twenty-one months due to instability as characteristics of color and textural properties which were obtained.

Determination of nucleosides and nucleotides in baby foods by hydrophilic interaction chromatography coupled to tandem mass spectrometry in the presence of hydrophilic ion-pairing reagents

In this work we propose a rapid and efficient method for the joint determination of nucleosides and nucleotides in dairy and non-dairy baby foods based on hydrophilic interaction chromatography coupled to tandem mass spectrometry in the presence of diethylammonium (DEA) as a hydrophilic ion-pairing reagent (IP-HILIC-MS/MS). Sample treatment of the baby food included dilution with water and centrifugal ultrafiltration (CUF) with an additional washing step that notably improved the global performance of the process. Later dilution of the extract with acetonitrile allowed adequate separation in the HILIC system. With the proposed treatment, we obtained extraction recoveries higher than 80% and, additionally, no matrix effects were observed. The CUF-IP-HILIC-MS/MS method was validated according to the 2002/657/EC decision and was used for the quantification of nucleotides and nucleosides in sixteen samples of commercial baby foods.
