How the Biotech Industry is Making Flavors Healthier and Eco-Friendly

The meals business is underneath strain to create products that don’t just taste nice, however which might be additionally good for our health and for the surroundings. Biotechnology is rising as an answer to take pleasure in the flavors we love with out damaging our our bodies or nature.

We’ve been including taste to our meals since historic occasions. Throughout historical past, spices have been a type of foreign money resulting from their worth. In the present day they are extra of a commodity, but many people would find it troublesome to stay without tasting the flavors of our favorite foods and drinks.

Flavorings have been historically produced by extracting molecules from crops. Right now, lots of them are produced utilizing chemical engineering. Take vanillin, the molecule that provides vanilla its attribute flavor. You’ll virtually definitely have eaten it sooner or later in ice cream, chocolate, muffins or soda drinks. Most of the vanillin used right now is produced in a petrochemical course of, with just one% coming from the precise vanilla plant.

In recent times, a third various has infiltrated the flavoring market: biotechnology. Most of these corporations are using yeast or bacteria to supply flavoring compounds via fermentation. The biotech business is taking up the flavoring market because of the advantages it presents compared to traditional methods. I obtained in contact with several corporations in the area to seek out out more about the a number of ways this know-how can make flavors higher than ever.

Healthier sweeteners

One among the most in-demand products in the taste business is sugar. However excessive sugar consumption is now being blamed for inflicting diabetes, obesity and heart disease at an epidemic degree, and everyone is in search of options. Biotechnology is already tapping into this market — the Swiss firm Evolva developed a way to supply the sweetener stevia via fermentation that is bought by Cargill.

Nevertheless, an enormous challenge stays for changing sugar with more healthy options. “The food industry wants to replace sugar across almost all food and drink categories. It’s been very successful in doing that from drinks. Pepsi Max is now 26 years old — that was one of the first sugar-free soft drinks on the market. Twenty-six years later, the problem has still not been solved for solid food,” Tom Simmons, CEO of Stem, advised me.

Stem (beforehand generally known as Cambridge Glycosciences) is creating a biological technique to extract, from crops, pure compounds that can be utilized as sweeteners beyond soda drinks. “It’s harder to replace sugar in solid food because sugar plays roles in the texture, it browns, it caramelizes, it crystallizes,” Simmons advised me. “You could add stevia to a cake mix and take out the sugar and it would in principle be sweet, but it wouldn’t actually taste like a cake because it would just lack all the texture.”

To beat this situation, the company is focusing on pure compounds that have a chemical construction more just like that of the sugar we extract from sugar beet or sugar cane. Stem is first aiming to enter the baking market, in merchandise similar to cookies and biscuits. The last word aim is to enter all types of meals markets at a worth that is aggressive with sugar. “As much as the food industry wants to be healthy it really is driven by economics. To hit mainstream markets you need to have low prices,” stated Simmons. As the company scales up production from kilograms to tons, he expects to be able to achieve aggressive pricing in a 5-year timeframe. In the meantime, they may concentrate on markets which might be prepared to pay a premium for more healthy options.

Consistent provide

When in comparison with the conventional extraction of flavor molecules from crops, biotechnology can provide a useful advantage: consistency. Seasons makes the amount, high quality and worth of uncooked material fluctuate wildly all through the yr.

“We’ve seen cases, for instance with vanilla, in which significant weather changes affect the whole harvest and you cannot buy the ingredients. Suddenly you cannot make natural ice cream vanilla flavor,” stated Martin Plambech, CEO of Biosyntia, a Danish company engaged on enhancing the manufacturing of chemical compounds using industrial biotechnology. “Biotechnology is an alternative way of delivering a more natural solution, but significantly more stable from the supply perspective and price perspective.”

That’s one in every of the largest sell factors of Isobionics, a Dutch biotech firm that provides flavors and fragrances of orange, grapefruit, bergamot, and ginger among others. “We started with producing valencene, which has an orange smell and taste,” Toine Janssen, founder and CEO of Isobionics, advised me. “We produce it the same way you would produce beer and it is equal to the valencene you would get out of the orange or the orange peel. It’s that simple.”

“The most important advantage is that it’s not harvest-dependent. You can normally only buy valencene once or twice per year. The flavor depends on how much sun it’s got and how much rain it’s got,” he defined. “We’ve been producing the same flavor for more than 10 years. It’s very stable, always smelling and tasting the same, and we can always produce as much as we want.”

This know-how gets around disruptions in harvesting brought on by droughts and crop illnesses. “At this moment, there’s a large greening disease in Florida which has lowered the production [of oranges] from 250 million boxes to around 70 million boxes per year. We have a very good alternative for these products. Our price is the same, but our advantage is bigger.”

Isobionics has been selling its fermented valencene since 2010 and creating processes to supply three to four new pure flavors yearly. Janssen has seen that demand is there and that the market for the biotech various is growing, very quick.

Better for the surroundings

When compared to conventional sources, biotechnology provides an alternative choice to produce flavors and smells that may scale back the harm to the surroundings. Even pure sources can have an enormous destructive influence on the surroundings. Vanilla has develop into infamous for the deforestation it is inflicting in Madagascar, and the processing of the beans creates toxic wastewater.

When growing oranges, a whole lot of water is needed, and it often needs to be transported as they are typically grown in places with more arid climates, akin to Spain or Israel. The fruit then needs to be transported, reduce, peeled and distilled to take out the molecule that provides them taste.

“In oranges, there is less than 0.04% of valencene,” Janssen explained. “For one liter of valencene, you need 160.000 oranges. We need not even a kilogram of sugar to make the same amount of valencene with the other products.”

It’s the similar state of affairs for many pure flavor compounds. “You would need the harvest more than a hectare of raspberries to produce one gram of their aroma. You’d need a damn lot of raspberries which are way better to eat than to produce aroma,” stated Nicolai Assenmacher, Product Supervisor at Phytowelt GreenTechnologies. This biotech company uses fermentation to supply R-alpha-lonolone, the major compound behind the flavor and odor of raspberry.

Like Isobionics, Phytowelt makes use of sugar for fermentation, but the company is wanting into the risk of utilizing wooden extracts as the uncooked materials to make the course of more sustainable. “We try to get more into circular bioeconomy and use renewable feedstock to produce a product that is independent of oil,” Assenmacher advised me.

Although their raspberry aroma is bought at a better worth, its quality is higher than these produced synthetically. The petrochemical processes additionally yield other molecules that, although chemically just like R-alpha-lonolone, don’t contribute any flavor or might be poisonous in bigger quantities.

General, the reduction of the influence on the setting could be vital. “More and more people are interested in the sustainability perspective. With the processes that we look at, we look at the life cycle assessment and we have estimated that we have more than 90% lower chemical waste and 80% less CO2 emissions. We know for a fact that there’s a significant sustainability benefit,” stated Plambech.

Biotechnology on your plate

As the demand for more healthy, greener, and general higher options for putting flavor on our plates grows, biotechnology will probably be more and extra present in the food we eat. Considered one of the key limitations to turn out to be mainstream is pricing. Many chemical methods have been optimized to supply flavor molecules which might be in excessive demand at extraordinarily low costs. In contrast, creating biotechnological options from scratch requires a big investment.

“First, we’ll probably see biotech solutions for the most expensive flavors where there’s a challenge with the chemical supply. Then, I think biotech will evolve to become better and better. You will see biotech rapidly going to lower and lower prices,” stated Plambech. “But it’s not going to happen overnight.”

His company, Biosyntia, is actively tackling this drawback with a know-how to determine strains of micro organism which might be optimized to supply a selected compound. As Plambech puts it, whereas others look for a needle in a haystack, their technique is like burning down the haystack to seek out the needle. With applied sciences like this, biotech is getting closer to taking up the taste business.

“We will be delivering products that are better for the body and available at the same cost as the chemical version. On top of that, we save the environment from tons of carbon dioxide and chemical waste. It’s just better on all fronts,” added Plambech.

Corporations like Isobionics are already reliably producing giant quantities of pure flavors using biotechnological methods, and making a profit — something nonetheless relatively uncommon in the industrial biotech world. “We’re just at the beginning,” stated Janssen. “We are focusing on these compounds for now but there are 40,000 to go.”
