Chemical Residue Testing

Though chemicals such as pesticides and sulfites are initially incorporated into commodities for reasons that may be beneficial, residues of such may compromise the health of consumers due to their toxicity or allergenic potential. As a result, the government either bans usage or regulates these substances to ensure that maximum allowable limits are not exceeded. Test kits offer rapid and accurate detection of these chemicals after a simple procedure validated for a variety of matrices.

The following are some of the common adulterants found in the food supply chain:

PesticideMost crops are treated with pesticides. Pesticides enable farmers to increase crop yields, preserve product quality, and extend shelf life. However, pesticides can pose harmful effects upon exposure and ingestion.
GMOGenetically Modified Organisms (GMO) undergo a lot of biochemical processes with increasing GMO production around the globe, regulatory standards were established in order to facilitate trade and safety of GMO products for human consumption.
Meat and Bone MealMeat and bone meal is a valuable protein source in feed production. However, it was determined as the cause of the spread of Bovine Spongiform Encephalopathy (BSE) or mad cow disease. In order to prevent the spread of BSE, most countries have imposed restrictions, and even outright bans, on the use of ruminant by-products and proteins in feed for ruminants.
MelamineMelamine is a chemical used in a variety of industrial processes and can be found in food contact surfaces in processing plants, can coatings, dishware, and other kitchenware. Furthermore, it was also used illegally to increase the apparent protein content in food samples such as milk.
SulfitesSulfites are most often used as antimicrobial and antioxidant agents in food and beverages, particularly in wine-making during the fermentation process. Due to potential adverse reactions of intolerant individuals and other food safety concerns, total sulfite content is commonly regulated by government agencies to not exceed 10 ppm.
MethanolMethanol is a highly flammable and poisonous liquid. Unscrupulous producers resort to intentionally adding methanol to alcoholic beverages as a cost-effective substitute for ethanol. Moreover, beverages rich in pectin, such as those derived from grapes and berries, can inadvertently lead to elevated levels of methanol during the fermentation process. In a proper and hygienic fermentation environment, methanol is produced at minimal and safe concentrations. However, when fermentation takes place under unsanitary conditions, methanol production can occur at higher levels. Methanol consumption, even in small amounts, can lead to severe health consequences, including blindness, organ failure, and death, to name a few.
Alkaline PhosphataseAn essential process in the production of safe and pathogen-free milk is pasteurization. Alkaline phosphatase is an enzyme naturally present in all raw milk, but is destroyed during pasteurization. The Alkaline Phosphatase test is used by dairy farms and processors and food producers to determine whether milk has been sufficiently pasteurized, or whether it has been contaminated with raw milk after the process of pasteurization.
