Synthetic biology, simply put, is the application of engineering concepts and methods to redesign and modify organisms, or to construct entirely new biological systems with specific functions from scratch.

D-allulose changed from a laboratory sample to a low-calorie beverage ingredient on store shelves. Vitamin K2 changed from a chemically synthesized “industrial product” to a fermentation-derived “natural active ingredient”. The price of ergothioneine dropped from tens of millions of yuan per kilogram to tens of thousands of yuan per kilogram. These industrial changes seem independent. But they all point to the same core driving force. It is the change of biotechnology fermentation supported by Synthetic Biology.Synthetic

It the industrial breakthrough of the three major star ingredients.

1、D-Aloinose: Synthetic Biology helps rebuild the sugar substitute industry

D-Aloinose makes up only 0.01% of figs. It was once regarded as a “laboratory treasure”. The reason is that its extraction cost is too high. Early on, Talai and Songgu Chemicals laid out many patents. This made them a “technical stronghold” in the artificial sweetener field. Domestic enterprises’ breakthrough started with enzymatic conversion technology. This technology is a core application of Synthetic Biology. People used Synthetic Biology tools to optimize D-aldonic acid-3-anti-isomerase. This enzyme can directly turn fructose into the target product under mild conditions. It also reduced by-products by more than 60%.

Now, this sugar substitute is widely used in baking and beverages in North America. Its sweetness is 70% of sucrose. Its calories are only 1/10 of sucrose. In 2025, it was approved as a new domestic food ingredient. Many enterprises are accelerating their expansion plans. A “sweetness revolution” driven by Synthetic Biology is coming soon in the artificial sweetener industry.

2、Vitamin K2 (MK-7): Synthetic Biology creates better bone health ingredients

For a long time, chemical synthesis has been the main way to produce traditional Vitamin K2. Products mainly containing MK-4 are cheap. But their bioavailability is less than 10%. People discovered Bacillus natto. They also used Synthetic Biology for precise regulation. This completely changed the situation.

Synthetic Biology enhanced liquid high-density fermentation technology. This technology makes Bacillus subtilis efficiently synthesize MK-7 in an optimized culture medium. People used multiple stages of membrane separation and purification. The proportion of all-trans structures in the product reached 99.95%. Its activity is more than three times that of chemically synthesized products. This fermented Vitamin K2 is a classic achievement of Synthetic Biology in the health ingredient field. It can make calcium deposit in bones instead of blood vessels. So it has unique advantages in bone health products.

3、Ergothioneine: Synthetic Biology causes “price collapse” of anti-aging ingredients

Once, one kilogram of ergothioneine cost as much as a house in a first-tier city. German companies monopolized the market with patented natural extraction methods. Domestic enterprises spent more than 40% of the final product cost on importing raw materials. Synthetic Biology completely broke this monopoly.

People used Synthetic Biology technology to modify the metabolic pathway of Escherichia coli. Ergothioneine was originally extracted from edible fungi. Now it can be mass-produced in fermentation tanks. Its purity exceeds 99%. The fermentation period was shortened from the traditional 14 days to 5 days. Technological breakthroughs led to a surprising “price collapse”. It dropped from 30 million yuan per kilogram to 90,000 yuan per kilogram. This is a reduction of more than 300 times.

The application process of this new food ingredient is advancing. This natural antioxidant is slowly spreading from high-end skin care products to oral beauty foods. Synthetic Biology leads the anti-aging market into an era of “democratization”.

Synthetic Biology, automated fermentation and precise purification technologies work together. The production of functional raw materials is undergoing three changes:

• Cost: Synthetic Biology shortens the process and improves efficiency. This can reduce the cost of scarce components. It also makes these components enter the mass market.
• Quality: The focus changes from “meeting standards is enough” to “maximizing activity”. Trans-10 MK-7 and high-purity ergothioneine are examples. Synthetic Biology optimized both of them.
• Application scope: It expands from a single field to multiple scenarios. For example, D-aldose can not only be used as a sugar substitute. It can also improve the flavor of baked foods through the Maillard reaction. Synthetic Biology makes its large-scale production possible.

Synthetic Biology drives this industrial revolution. It will finally change health products from “concept marketing” to “technology-driven”. This provides consumers with truly valuable functional experiences.
