Risk Assessment of Using Aluminum Foil in Food Preparation

Risk Assessment of Using Aluminum Foil in Food Preparation

Nowadays, it is a common practice to wrap meat and fish prior to oven cooking. Due to the possible relation between aluminum uptake and the specific diseases mentioned in many literatures, it is important to determine the aluminum concentration in the food wrapped with aluminum foil. The levels of aluminum content in different types of meat (beef, water buffalo, mutton, chicken, and turkey) packed with aluminum foil and cooked in an oven at three different temperatures/time periods (150 ° C for 60 minutes, 200 ° C for 40 minutes, and 250 ° C for 20 minutes) have been studied. The results indicate that cooking increases the aluminum concentration in both white and red meats by 89 – 378 % in red meats and 76 – 215 % in poultry. The least increase (76 – 115 %) is observed in the samples baked for 60 min at 150 ° C, while the highest increase (153 – 378 %) is in the samples baked for 20 min at 250 ° C. It is determined that the fat content in meat, in addition to the cooking process, affected the migration of aluminum. It has been also found that raw chicken and turkey breast meat contained higher amounts of aluminum than the raw chicken and turkey leg meat, respectively. However, meals prepared in aluminum foil may carry a health risk in addition to other aluminum sources. The aluminum contents in grilled and baked fish fillets, with and without ingredients, wrapped in aluminum foil have been also studied [5]. The aluminum migration seems to depend on several factors, e.g. grilling duration, heating temperature, composition, food pH value, and presence of any other substances (such as organic acids and salt) [6]. Other studies indicate that the aluminum leaching for 1 – 3 hours beef baked samples in aluminum foil ranged between 59.83 – 220.20 mg/kg [7].

Carbon-coated Aluminum Foil as Current Collector for Improving the Performance of Lithium Sulfur Batteries

Carbon-coated Aluminum Foil as Current Collector for Improving the Performance of Lithium Sulfur Batteries

Most of Li-S batteries adopt bare aluminum foil (bare Al foil) as a current collector of sulfur cathode currently. This foil has limited contact area and weak adhesion ability to active material because of too smooth surface, which produces high contact impedance. Partial sulfur particles are inclined to separate from the bare foil at repeated charge-discharge cycles, causing capacity degradation of the cell. Besides, the bare foil is always easily corroded by the organic electrolytes [2, 3], which damages the electrochemical stability of the system and may give rise to self-discharge and safety issue [4]. To solve the problems, scientists have attempted various other metal or carbon based materials to substitute for bare Al foil, e.g., nickel foam, carbon foam, porous carbon paper, activated carbon fiber cloth, carbon nanotubes [5-9]. These current collectors have positive effects in cell performance. However, either complex manufacture process (accompanied by high cost) or difficulty of large-area fabrication impedes their practical applications. Besides, some alternatives have still a certain gap from the bare Al foil in conductivity. Therefore, it is necessary to further develop appropriate current collector materials for advanced Li-S batteries.

Estimating Aluminum Leaching into Meat Baked with Aluminum Foil Using  Gravimetric and UV Vis  Spectrophotometric Method

Estimating Aluminum Leaching into Meat Baked with Aluminum Foil Using Gravimetric and UV Vis Spectrophotometric Method

It is a common practice in many countries to bake fish, shrimp, and chicken and meat stakes by wrapping them in Al foil. Even many cooking books and cooking programs use this practice because of the most important characteristics of aluminum foil that is its ease of handling, ability to transmit heat and its impermeability to gasses. The excessive use of Al foil in baking and the disagreement about using Al foils motivated me to do this study especially after the 2007 WHO/FDA Report. The purpose of this investigation is to estimate the amount of Al leaching from fish, chicken and meat baked in Al foil using a cheap weight loss (WL) and UV-Vis spectro- photometric method. Then compare the results with PTWI from WHO/FDA.

A comparison of material preferences by chocolatiers and consumers

A comparison of material preferences by chocolatiers and consumers

Color on packaging plays an important role because it can influence thinking, change actions and cause reactions. It can irritate or soothe consumers’ eyes, increase their blood pressure and increase their appetite. Packaging colors are selected for certain holidays/events, for example, red, green, white, gold and silver are commonly associated with Christmas. The preferences of the target audience showed that 70% of consumers from the survey ranked color on aluminum foil wrap as second highest as it creates positive moods. As for other consumers who do not favor vibrant colors, clear color themed bags were preferred. The data depicted 30% of the consumers ranked stimulation from color on clear cellophane bags as 3 rd .

Significantly higher seed germination (48.67%), seedling height (28.83cm), seedling diameter, number of laterals, and length and diameter of laterals were recorded in extra large seed of chestnut (Castanea sativa Mill) . Although seed stored in aluminum foil pouch exhibited maximum germination per cent (47.75%), the maximum seedling growth was registered in sand storage condition. Large seeds stored in sand and aluminum foil pouch resulted in good germination and seedling growth. Significantly maximum seed germination (33.5%) was registered in soil + sand (media), whereas other growth parameter was highest in field sown seedling. November sown seeds resulted in maximum germination (45.5%) and seedling height; however, seedling diameter, number of laterals and diameter were highest in October sown seedling. Large seed and November sowing had highest germination (52.70%). Field sowing in month of November resulted in maximum seedling height and diameter, length of laterals and their diameter.

In vitro propagation of Gentiana scabra Bunge – an important medicinal plant in the Chinese system of medicines

It is essential to close a culture container with some closure material to maintain sterility of the cultures. Dif- ferent types of container closure materials like micro- pore, parafilm, and polyvinyl chloride for eggplants (Ribeiro et al. 2009), plastic films for neem (Rodrigues et al. 2012) have been used. In our laboratory, aluminum foil and dispense paper have been used successfully to improve ventilation for cultures of Scrophularia (Chen et al. 2006a), and Bupleurum (Chen et al. 2006b). It has been reported that the type of closure affects gaseous ex- change, availability of water, micronutrients, and balance of hormones in the culture container (Kataeva et al. 1991; Lai et al. 2005; Chen et al. 2006a; Tsay et al. 2006). The head space of culture vessels with low ventilation, accumulates various gaseous compounds like ethylene and carbon dioxide (Akhter Zobayed et al. 2001; Lai et al. 2005). These undesirable compounds can alter bio- chemical responses and leaf development of in vitro cul- tured plants (Pierik et al. 2007) and also affect enzymes involved in oxidative activities (Synková and Pospíšilová 2002). Some closures cause restriction of gaseous exchange between the container atmosphere and the out- side environment (Buddendorf-Joosten and Woltering 1994), which can result in poor aeration and hyperhydric condition of cultures. Also, growth rate and other physio- logical and morphological characteristics of plants devel- oped under in vitro conditions can be influenced by the physical and chemical micro-environments of culture con- tainers (Walker et al. 1988).

Anodization of nanoporous alumina on impurity induced hemisphere curved surface of aluminum at room temperature

Anodization of nanoporous alumina on impurity induced hemisphere curved surface of aluminum at room temperature

Nanoporous alumina which was produced by a conventional direct current anodization [DCA] process at low temperatures has received much attention in various applications such as nanomaterial synthesis, sensors, and photonics. In this article, we employed a newly developed hybrid pulse anodization [HPA] method to fabricate the nanoporous alumina on a flat and curved surface of an aluminum [Al] foil at room temperature [RT]. We fabricate the nanopores to grow on a hemisphere curved surface and characterize their behavior along the normal vectors of the hemisphere curve. In a conventional DCA approach, the structures of branched nanopores were grown on a photolithography-and-etched low-curvature curved surface with large interpore distances. However, a high- curvature hemisphere curved surface can be obtained by the HPA technique. Such a curved surface by HPA is intrinsically induced by the high-resistivity impurities in the aluminum foil and leads to branching and bending of nanopore growth via the electric field mechanism rather than the interpore distance in conventional approaches. It is noted that by the HPA technique, the Joule heat during the RT process has been significantly suppressed globally on the material, and nanopores have been grown along the normal vectors of a hemisphere curve. The curvature is much larger than that in other literatures due to different fabrication methods. In theory, the number of nanopores on the hemisphere surface is two times of the conventional flat plane, which is potentially useful for photocatalyst or other applications.

Measurement of antibacterial properties of foil-backed electrospun nanofibers

Measurement of antibacterial properties of foil-backed electrospun nanofibers

Aluminum foil can prevent bacterial growth by exclusion of atmosphere, nutrients, and moisture (Dogan et al. 2009). On the other hand, these items would be in rich sup- ply on the surface of the skin, and so aluminum foil would not be able to effect suppres- sion of bacterial growth through this mechanism if the foil-backed nanofiber material were applied in contact with skin. To determine whether aluminum foil alone, or foil- backed 100% acetate nanofibers alone, provided any antibacterial effects, initial anti- bacterial testing runs included samples of aluminum foil backing without nanofibers, in addition to foil-backed 100% acetate nanofibers and foil-backed acetate nanofibers made with cold-pressed hemp seed oil or full-spectrum hemp extract. No effective antibac- terial qualities were observed for either the aluminum foil backing without nanofibers or for foil-backed 100% acetate nanofibers alone (Figs.  3b, c, 4). Compared to the ini- tial bacterial load applied, aluminum foil backing without nanofibers permitted a 1153%

Refractance Window and Conduction Dryings of Mango Pulp

Refractance Window and Conduction Dryings of Mango Pulp

radiation heat transfer took place through Mylar sheet and the product dried up to nearly zero free moisture content, if drying process continued as shown in Figure 2. Figure 3 shows the plots of drying rate as function of drying time. As evident, the peak drying rates are not conclusively established from this figure. Plotting the drying rate as function of moisture content (dry basis) in Figure 4 reveals the maximum drying rates of 0.0024 and 0.0029 kg water m -2 s -1 for Mylar sheet and aluminum sheet, respectively. No constant rate of drying could be identified from the data for aluminum foil. The larger value of maximum drying rate for aluminum sheet is justified as the thermal conductivity value for aluminum is of the order of 200 W m -1 K -1 as compared to the same value for Mylar of 0.2 W m -1 K -1 . The drying rate values also confirm that nearly equal level of drying rates for Mylar sheet through IR radiation and for aluminum sheet by conduction. These values of drying rates for Mylar sheet and aluminum sheet correspond to dry basis moisture content of 3 and 4.5 kg water kg -1 dry

mantic similarity between the original word and the foil (computed as the cosine between the two corresponding word2vec embeddings Mikolov et al. (2013)); 2) frequency of original word in FOIL-COCO captions; 3) frequency of the foil word in FOIL-COCO captions; 4) length of the caption (number of words). The mixed-effect model was performed to get rid of possible effects due to ei- ther object supercategory (indoor, food, vehicle, etc.) or target::foil pair (e.g., zebra::giraffe, boat::airplane, etc.). For both LSTM + norm I and HieCoAtt, word2vec similarity, the frequency of the original word, and frequency of the foil word turned out to be highly reliable predictors of the model’s response. The higher the values of these variables, the more the models tend to provide the wrong output. That is, when the foil word (e.g. cat) is semantically very similar to the original one (e.g. dog), the models tend to wrongly classify the caption as ‘correct’. The same holds for frequency values. In particular, the higher the frequency of both the original word and the foil one, the more the models fail. This indicates that systems find it difficult to distinguish related concepts at the text-vision interface, and also that they may tend to be biased towards frequently occurring concepts, ‘seeing them everywhere’ even when they are not present in the image. Caption length turned out to be only a par- tially reliable predictor in the LSTM + norm I model, whereas it is a reliable predictor in HieCoAtt. In particular, the longer the caption, the harder for the model to spot that there is a foil word that makes the caption wrong.
