Sample preparation is one of the most critical steps in your analytical process. Any errors within the sample preparation process will undermine the quality of your food data at all subsequent stages of your analysis. Here are five tips to improving your sample digestion for food samples. Consumers are exposed to low levels of heavy metals on a daily basis and long term exposure can have negative health impacts.
Since the elements themselves are distributed unevenly throughout, for example, cereal grain, with the germ and the outer layers having the highest concentrations, analyzing these grains to detect low analyte levels with accuracy and controlled reproducibility is a challenge. The atomic absorption analysis technique provides a high performance option with features like a closed-furnace design that is sealed at both ends with easily removable bayonet-mount windows. In addition, independently controlled external and internal gas streams provide maximum flexibility, tube life, and sensitivity.
Atomic spectroscopy is a family of techniques for determining the elemental composition of an analyte by its electromagnetic or mass spectrum. Several analytical techniques are available:.
For many years, graphite furnace atomic absorption spectrophotometry GFAAS has been a reliable technique and the preferred method for this heavy metals analysis of tea leaves. Elemental analysis of fuel oil is an important step in quantifying its quality.
Arsenic can find its way into food through a variety of paths. In the recent past, various organic arsenicals were used as herbicides and antimicrobial agents in growth fields as well as applied directly on fruits and fruit trees. Contamination of industrial and municipal water supplies with arsenic As , selenium Se , and mercury Hg can occur from natural deposits, industrial discharge, runoff from mining, landfill and agricultural operations.
Ingestion of trace elements from food can be linked to nutrition, disease, and physiological development. Whether they are needed for proper nutritional value or contain toxic elements, the presence of major and minor elements in food needs to be verified to help determine health effects for the consumer. Acute or chronic exposure to heavy metals can lead to damaged nervous system function and have detrimental effects on vital organs. Food safety laboratories performing these analyses are often high-throughput and require a detection tool that is efficient and cost effective.
Metal determination in the sub-ppb range are required for the analysis of complex sample matrices and corrosive acids. To meet these requirements, high-performance analytical techniques such as inductively coupled plasma mass spectrometry ICP-MS are preferred for rapid multi-element analysis, however, diagnosing problems can also involve only a few elements, in which graphite furnace atomic absorption spectrometry GFAAS is recommended.
This work demonstrates the ability to measure several elements in beer with Flame atomic absorption using the PinAAcle No significant differences were observed between beers in glass bottles or metal cans. Fortified breakfast cereals are an important source of nutrition for children, and consumers have come to expect high quality from a variety of cereals and continue to select fortified products over non-fortified products in the marketplace.
The efficient production of these nutritionally fortified breakfast cereals requires careful formulation and uniformity batch to batch. Ongoing analytical measurement of nutritional additives and the total micronutrient content in the cereal is one way in which food producers can quantify the quality and consistency of their cereal products.
With an increased focus on healthy living and the consumption of healthy foods, interest in the nutritional quality of the fruit we consume has become more important. When fresh fruit is not available, dried fruit is often substituted, and manufacturers and customers would like to know that the dried fruit has not lost some nutritional value during processing.
One way of monitoring the quality of fresh or dried fruit is by measuring the micronutrient concentration contained within. Micronutrients are represented by trace elements considered to be nutritionally valuable, and it is these elements that can be analyzed via various inorganic analytical methods.
There is an increasing need to monitor the essential element levels in food samples at ever decreasing concentrations. For this purpose, very sensitive, yet rapid and inexpensive methods are necessary. Compared with other techniques, FAA has the characteristics of good precision and simplicity with lower cost and minimum operator proficiency. Foods, infant formula, milk, and water provide significant exposure routes for metal contaminants. The effect of lead exposure at low levels has been well established and levels below toxic have been shown to contribute to behavioral and learning issues.
GFAA has detection limit capability well below the level of concern and provides an economical choice for smaller laboratories or those with a smaller workload. ICP-MS provides excellent detection limits and offers efficient multielement capability for the detection of other hazardous elements in the same run, such as lead.
This work demonstrates the ability of the PinAAcle Flame AA spectrometer to accurately measure major components in drinking waters. When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest.
There are many mineral dietary supplements available in today's marketplace to ensure that mineral deficiencies do not occur in one's diet. The mineral content of these products must be verified for quality control purposes. Graphite furnace atomic absorption spectrophotometry GFAAS has been widely applied to the determination of trace elements in food due to its selectivity, simplicity, high sensitivity, and its capability for accurate determinations in a wide variety of matrices.
Edible oils are generally low in trace element concentrations, however, metals such as arsenic As , lead Pb , cadmium Cd , chromium Cr , and selenium Se can be found and are known for their toxicities which affect the health of consumers. The determination of the inorganic profile of oils is important because of the metabolic role of some elements in the human organism. On the one hand, there is knowledge of the food's nutritional value, which refers to major and minor elements.
Precise and accurate measurements at the regulated levels are an important factor for assuring safe drinking water. EPA Method In evaluating a GFAAS system for determination of these elements, it must provide good sensitivity, low noise, limited drift, and accuracy in matrices with high salt content hard water that might be found in drinking waters.
