Please be aware of the following:
It is a method that uses ultralow temperature and vacuum to remove moisture from food.
The loss of moisture in food prevents the growth of microorganisms, helping its preservation.
Also, unlike high-heat drying, freeze-drying preserves food nutrients and flavor. You can enjoy natto flavor, aroma, and nutrients in all our products.
We use pure natto and freeze-dry it to make natto snacks. From the moment you open the package, you can smell the fragrant natto. Okinawa brown sugan and sea salt presentations have slightly less natto aroma.
Calories depend on the amount of protein, fat, and carbohydrates. In particular, the amount of fat affects the total calories. The formula for calculating calories is {(protein + carbohydrate) x 4} + {(lipid) x 9}. Therefore, there will be some differences depending on the product.
In the case of brown sugar snacks, the water content is a little bit higher than the others, it makes look nutritional component and calories content lower. However, in terms of sugar comparison, the brown sugar snack has the highest amount of carbohydrates. The sea salt snack contains sunflower oil, making it to be the highest in calories.
However, there is not a broad difference between the three types of snacks.
