The importance of preserving food nutrition and flavor
Food preservation is an important factor in the food supply chain. Preservation not only helps to extend the shelf life of the product but also maintains its quality, nutrition and taste.
Foods are rich in vitamins, minerals and antioxidants, but they are very sensitive and easily damaged when exposed to the outside environment. If not stored properly, foods will lose their nutritional value and flavor, causing damage to consumers and manufacturers.
Taste and nutrition – the factors that determine food value
Flavor and nutritional value not only determine product quality but also directly affect the health and experience of consumers. However, conventional preservation methods such as sun drying or heat drying often cause a significant loss of nutrients and natural flavors of food, affecting the value of the product.
The need for safe and sustainable food preservation
In the context of consumers increasingly interested in clean and safe food, businesses must seek preservation solutions that are not only effective but also ensure original quality. This is the reason why SUNSAY freeze-drying technology becomes the ideal choice.
What is SUNSAY freeze drying technology?
SUNSAY freeze-drying technology operates on the principle of drying food at low temperatures (35-50°C) using dehumidified cold air. This method helps to retain maximum nutrition and flavor of food, limiting the state of chemical change.
The freeze drying process includes:
- Cool the product quickly.
- Maintain a constant low temperature throughout the drying process.
- Absorbs moisture from food through cold air flow, gradually drying without changing the structure or chemical composition.
- As a result, the dried product does not shrink, retains its shape, color, flavor and nutritional content.
Outstanding advantages of SUNSAY freeze-drying technology
Thanks to low temperatures, SUNSAY freeze-drying technology helps protect sensitive nutrients such as vitamins, minerals and enzymes. Nutrient-rich foods such as fruits, vegetables or herbs after freeze-drying still retain their nutritional content, ensuring health value for consumers.
Freeze-dried products do not change flavor, lose color or burn like heat-drying methods. For example, freeze-dried mangoes retain their bright yellow color and natural sweetness; while kale remains crunchy and flavorful.
Freeze-drying technology reduces the moisture content of food to an ideal level, preventing the growth of bacteria, mold and oxidation. Freeze-dried products can be preserved for longer without the use of chemical preservatives.
Food drying machine is equipped with an intelligent heat recycling system, helping to save energy. In addition, the drying process does not generate toxic emissions, contributing to environmental protection.
