In the fields of food science and technology, people are always looking for new ways to keep food fresh and make it last longer. Trehalose powder is a substance that has gotten a lot of attention lately because it seems like it could be useful. Multiple organisms naturally contain this disaccharide. It has unique qualities that make it useful in the food business.
This detailed blog post discusses the role of trehalose in keeping food fresh and improving quality. It goes into detail about its unique properties, uses, and possible benefits.
Trehalose: What Is It?
Many living things, like bacteria, mushrooms, insects, and plants, contain trehalose, a disaccharide of two glucose molecules. It is a very important part of how these organisms stay alive, especially in harsh situations like freezing and dehydration. Trehalose’s ability to surround cellular parts with a protective glass-like state helps keep biological activity going.
Key Properties of Trehalose
- Water Activity Reduction: Trehalose has a low water activity, which means that it binds water molecules very strongly. This quality is necessary to stop the growth of microbes and enzymes, which extends the shelf life.
- Glass Formation: Trehalose can change into a glassy state, which is a very thick, solid phase. This state stops water and other parts from crystallizing to keep cellular structures from getting damaged.
- Stabilizing Proteins: Trehalose can stabilize proteins by stopping them from breaking down and sticking together. This quality is essential for keeping the structure and usefulness of foods that are high in protein.
- Antioxidant Activity: Trehalose has antioxidant qualities that help keep food safe from oxidative damage.
- Flavor Improvement: Trehalose can make food taste and feel better by adding a unique sweetness and making it smoother in the mouth.
Role of Trehalose in Food Preservation
1. Bakery Products
The bakery business uses trehalose a lot because it has unique properties that make it worthwhile. In baked goods, trehalose is a humectant that holds water molecules together and keeps them from drying out. This helps keep the texture soft and tender, which delays the start of staling. Trehalose can also stop the Maillard reaction, which turns food brown and changes its taste. This works exceptionally well for things that need a lighter color and a milder flavor. Trehalose can also make baked things look better by stopping them from turning brown. This makes them more appealing to customers.
2. Frozen Foods
Utilizing trehalose in frozen foods has big benefits when it comes to keeping their quality. Trehalose helps stop ice crystals from forming when things freeze, which keeps cell structures from getting too damaged. This makes the texture better and the look more appealing when it thaws. Trehalose can also keep proteins and other organic molecules from breaking down, which means that frozen foods retain their nutritional value and taste. Manufacturers can improve the quality of frozen foods and make them last longer by adding trehalose.
3. Confectionery
The confectionery industry uses trehalose to make different kinds of sweets taste better, last longer, and have better structure. Trehalose can stop sugar from crystallizing, which keeps sweets, chocolates, and gummies smooth and creamy. It can also help make these foods less sticky, which makes them more fun to eat. Trehalose can also help sweets release their flavors more fully, making the taste experience stronger and more enjoyable. Confectionery makers can make tasty treats that last longer by using trehalose.
4. Dairy Products
Dairy items, like ice cream and yogurt, use trehalose to make them taste better and last longer on the shelf. Trehalose can help keep ice cream from forming crystals, which makes the creaminess smoother and creamier. It can also make ice cream more stable when it freezes and thaws, making phase separation less likely and keeping the taste the same. Trehalose can help yogurt keep its thicker texture and stop syneresis, the process by which the whey splits from the curd. Manufacturing companies can make dairy goods that are not only tasty but also last longer and have a better texture by adding trehalose.
5. Meat Products
You can add trehalose to meat items to make them more tender, juicy, and last longer. Trehalose helps keep the meat from drying out and getting tough by holding on to water. In addition, trehalose can keep proteins from denaturing, which means that meat products stay soft and juicy. For things that are frozen and then thawed, this is especially helpful. By adding trehalose to meat goods, companies can make them taste better and last longer.
Benefits of Using Trehalose in Food Preservation
1. Extended Shelf Life: Trehalose can significantly increase food items’ shelf life by stopping microbes’ growth, enzymes’ activity, and oxidative damage.
2. Better Quality: Trehalose can improve the texture, flavor, and general quality of food products by keeping the moisture level steady, stopping crystallization, and keeping proteins stable.
3. Natural Preservative: Using Trehalose, a natural compound, instead of synthetic additives as a preservative makes it more appealing to people who want to buy goods with clean labels.
4. Versatility: Trehalose can be used in many different kinds of food, giving food makers many options for making their foods.

Challenges and Considerations
Even though trehalose has many benefits, there are also some problems and things to think about:
1. Cost: Trehalose can be more expensive than other stabilizers, which could stop many people from using it in some situations.
2. Sweetness: Regarding sweetness, trehalose is slightly less sweet than sucrose, so formulations may need to be changed to keep the desired taste qualities.
3. Regulatory Approval: In some countries, using trehalose in food items may need regulatory approval. This can make it harder for the global market to grow.

The Bottom Line
Trehalose powder has emerged as a viable food preservation and quality improvement ingredient. Its distinct features, such as water activity reduction, glass formation, protein stability, and antioxidant activity, make it an effective tool for increasing shelf life, texture, and sensory qualities. As research into trehalose’s potential in numerous food applications continues, its use will likely become even more prevalent. The food sector can create new, delicious, and sustainable goods using the power of trehalose.
