In the current era of continuous upgrading of food processing technology, freeze-drying technology is bringing about new changes to the tomato paste industry. Recently, a certain technology food company has launched a freeze-dried tomato sauce product. Through vacuum freeze-drying technology, it retains the nutritional components and natural flavor of tomatoes while providing a convenient "ready-to-eat" experience. This fills a market gap and has been favored by outdoor enthusiasts, office workers and other groups.

Traditional tomato sauce is mostly in liquid or paste form, which has problems such as being inconvenient to carry and having a shelf life greatly affected by temperature. Moreover, during the processing, some nutrients will be lost with moisture. The freeze-dried tomato sauce adopts a brand-new process: first, fresh tomatoes are made into the initial tomato sauce product, and then it is placed in a vacuum environment of -40 ℃ for freeze-drying, removing over 95% of the moisture in the product to form a easily soluble powder product. During this process, the lycopene, vitamins, minerals and other nutrients in tomatoes are fully retained, and due to the reduction of water content, the nutritional density is significantly increased.

According to tests by authoritative institutions, the lycopene content in every 100 grams of freeze-dried tomato sauce powder is as high as 120 milligrams, which is three times that of traditional liquid tomato sauce. The vitamin C content is 80 milligrams, and the nutritional density is increased by 40%. Meanwhile, the freeze-drying process can lock in the volatile aroma substances in tomatoes. After being mixed, it can quickly restore the flavor of fresh tomato sauce, and the taste is almost the same as that of freshly boiled tomato sauce. In addition, freeze-dried tomato sauce contains no additives. It only needs to be restored by adding an appropriate amount of water or edible oil, and its convenience far exceeds that of traditional products.

In terms of application scenarios, the advantages of freeze-dried tomato sauce are particularly prominent. For outdoor enthusiasts, the lightweight powder packaging is easy to carry and there is no need to worry about squeezing or leakage. When camping or hiking, just mix the powder with water and you can quickly make tomato-flavored camping meals, such as tomato-flavored fried rice and tomato soup. For office workers, it can be used as a convenient lunch seasoning, paired with instant noodles and multigrain rice. It not only enhances the taste of the meal but also provides nutrition. In terms of household emergency reserves, freeze-dried tomato sauce has a shelf life of up to 24 months and does not require refrigeration. It can be stored at room temperature, making it an ideal choice for household food reserves.
