With the miniaturization of family structures and the personalization of consumer demands, "small-sized" food has gradually become a new trend in the market. Recently, a certain food enterprise launched "small-portion fresh-packed" tomato sauce. Each bag has a net content of only 30 grams and is independently sealed in packaging. It can not only precisely control the dosage but also retain the nutrition and flavor of tomatoes to the greatest extent. After its launch, it quickly won the favor of single people, small families and parent-child families.

Traditional tomato sauce is mostly in large bottles weighing over 500 grams. After opening, it needs to be refrigerated and is difficult to use up in a short time. It is prone to bacterial contamination due to repeated use, which not only affects the flavor but may also cause nutrient loss. The "small-portion fresh-packed" tomato sauce is individually packaged at one time. Each bag just meets the needs of one cooking or consumption, so there is no need to worry about spoilage after opening.

In terms of nutrient retention, "small-portion fresh-packed" tomato sauce adopts the "aseptic filling and light-proof packaging" technology. After the tomatoes are processed, they are quickly filled into aluminum-plastic composite bags in a sterile environment to avoid oxidation and deterioration caused by contact with air. The packaging material has excellent light-blocking properties and can prevent ultraviolet rays from destroying the vitamin C and lycopene in tomatoes. After testing, it was found that the unopened "small portion fresh" tomato sauce, when stored at room temperature for six months, only saw a 5% decrease in lycopene content and an 8% drop in vitamin C content, which was far lower than the 20% nutrient loss rate of large-bottle tomato sauce within one month after opening.

In terms of flavor experience, the "small-portion fresh-packed" tomato sauce is kept sealed throughout the process, avoiding the problem of flavor mixing caused by repeated opening. Each bag can maintain the rich taste of fresh tomatoes. Consumers have reported that when making tomato-flavored breakfast sandwiches with "small-portion fresh" tomato sauce, the refreshing aroma of tomatoes can be smelled as soon as the package is opened. After spreading it evenly, every bite of the sandwich offers a natural sweet and sour taste, without the sourness that may occur in large bottles of tomato sauce after opening.
