The answer is a lot less interesting – but significantly more pleasant – for both humans and beavers. Where does vanilla flavouring in food and drinks actually come from? It is still used in some candles and perfume products, but almost never in food and drink. Why? Partly because it is not kosher, and partly because it is difficult to obtain in sizeable quantities. However, you do not need to worry, because you have almost certainly never ingested any. Manufacturers have been using it food and perfume for at least 80 years, according to a 2007 study in the International Journal of Toxicology. The US Food and Drug Administration lists castoreum as a “generally regarded as safe” additive. Castoreum, which is produced by beavers, can be used as vanilla flavouring (Photo: Wikimedia Commons)īeavers use it to mark their territory, but it can also be “milked” from anaesthetised beavers and used as a flavouring or scent in foods and perfumes. The brown slime-like substance has a musky, vanilla-like scent, because of beavers’ diet of bark and leaves. "Using microbes to turn waste plastics, which are harmful to the environment, into an important commodity and platform molecule with broad applications in cosmetics and food is a beautiful demonstration of green chemistry," Ellis Crawford, a medicinal chemist and editor at the journal Royal Society of Chemistry, says in a statement.įor future studies, the researchers are looking into how they can use the bacteria to increase the amount of TA converted into vanillin and scale the process so more extensive amounts of plastic can be converted at a time, reports the Guardian.Castoreum is produced in beavers’ castor sacs, which are located between the pelvis and the base of the tail, and yes, next to the anal glands. The bacteria only need to make a few changes to the number of hydrogen and oxygen atoms bonded to the acid's carbon ring, Live Science reports. Because both chemical compounds are similar, the microbes could easily transform the acid into vanillin. According to Saveur, custard, panna cotta, white cake, and crme brle are just a few of the many recipes that get their flavor from the sweet, woody aroma of vanilla. Crafted with pure vanilla extract and other natural ingredients. The mixture converted 79 percent of the TA into vanillin. Vanilla is one of the most popular flavors and it's put into just about every baking recipe and ice cream. Shop Wellsley Farms Blended Vanilla Flavoring, 16 oz. coli and TA at a temperature of 98.6 degrees Fahrenheit for a day, reports the Guardian. The team mixed a broth containing the engineered E. Building on this finding, researchers used a modified version of the bacteria Escherichia coli to convert the acid into vanillin. Previous studies found enzymes could break down plastic bottles made from polyethylene terephthalate (PET) into terephthalic acid (TA). The bacteria only need to make a few changes to the number of hydrogen and oxygen bonded to the acid's carbon ring. The microbes could transform the acid into vanillin because both chemical compounds are similar. For every one million plastic bottles sold each minute globally, only 14 percent is recycled, reports the Guardian. Vanillin is produced artificially to meet demands that the vanilla bean supply can't meet, reports Yasemin Saplakoglu for Live Science.Ĭurrently, single-use plastics lose 95 percent of their value after use, causing a $110 billion loss to global markets every year, USA Today reports. Eighty-five percent of the world's vanilla is synthesized from fossil fuels in a two-step process, per the Independent. Normally, the chemical compound is distilled from the extract of vanilla beans however, it can also be made synthetically. ![]() ![]() It is found in various items, including dairy products, soda, and cosmetics, reports Asha C. Vanillin is what gives vanilla its signature sweet aroma and potent flavor. "This is the first example of using a biological system to upcycle plastic waste into a valuable industrial chemical and this has very exciting implications for the circular economy," study author Joanna Sadler, a biochemist at the University of Edinburgh, says in a statement.Īs a lucrative spice, vanilla has a market value predicted to reach $724.5 million by 2025 as demand rapidly increases, reports Kate Ng for the Independent. This study marks the first time researchers brewed up a "valuable" chemical compound from plastic waste, reports Damian Carrington for the Guardian. To meet the demands for vanillin, the primary component of vanilla bean extract, and reduce plastic waste, researchers are converting plastic into vanilla flavoring using genetically engineered bacteria, according to a new study published in Green Chemistry. The castor gland, located underneath the beavers tail distressingly close to the anus, produces a slimy brown substance called castoreum. Scientists have found an innovative approach to combat the global plastic waste crisis and make something sweeter in the process.
