Description

Technical Field

[0001] This utility model belongs to the field of food preservation and packaging technology, and is applied to additive-free fermented pasta, especially relating to a preservation packaging structure for Chinese fermented filled pasta. Background Technology

[0002] Currently, there are generally two common packaging methods for Chinese-style fermented filled pasta (such as steamed buns and stuffed bread): One is modified atmosphere packaging (MAP) for ambient temperature preservation. Its core principle is to adjust the gas composition (such as the ratio of oxygen, carbon dioxide, and nitrogen) within the packaging to inhibit microbial growth and delay oxidation reactions, thereby extending the food's shelf life. However, this technology requires high barrier properties in the packaging materials and necessitates the use of sterilization and gas-filling equipment, resulting in high equipment costs. It is generally more suitable for use in central kitchens. The other method uses quick-freezing technology combined with low-temperature resistant packaging materials to significantly extend the food's shelf life and maintain its quality. However, this technology requires cold chain logistics for distribution, and in situations where ambient temperatures are difficult to maintain, frozen food may thaw and spoil.

[0003] In summary, current common packaging solutions cannot meet the needs of selling and storing Chinese-style fermented pasta, whether filled or unfilled, at room temperature after being removed from cold chain storage and transportation, without increasing costs too much. Therefore, a new packaging structure needs to be designed. Summary of the Invention

[0004] This utility model provides a preservation packaging structure for Chinese-style fermented filled pasta to solve the technical problems existing in the prior art. It has the characteristics of simple structure, convenient operation and low cost. Moreover, the pasta dough and filling can be extended in terms of shelf life without the need to add any preservatives.

[0005] This utility model includes the following technical solution: a preservation packaging structure for Chinese-style fermented filled pasta, comprising a pre-sterilized sealable holding unit and an aluminum foil sealing bag; the aluminum foil sealing bag can completely contain the holding unit and, after vacuuming, completely wraps the holding unit; the holding unit can hold at least one pasta. The aluminum foil sealing bag is vacuumed, then sterilized at high temperature and cooled to room temperature. By combining vacuuming and high-temperature sterilization of the aluminum foil sealing bag containing the holding unit, the growth and reproduction of microorganisms can be effectively prevented, reducing the contact between the pasta and the external environment, thereby significantly extending the shelf life of the pasta.

[0006] Furthermore, the holding unit is a high-temperature resistant covered box to facilitate sterilization by high-temperature steam.

[0007] Furthermore, the box body is made of polypropylene plastic, bamboo, or borosilicate glass or stainless steel. Borosilicate glass and stainless steel boxes can be recycled and reused.

[0008] Furthermore, the box body is cylindrical in shape.

[0009] Furthermore, a sealing ring is provided inside the lid of the box body.

[0010] Furthermore, the lid and the main body of the box are detachably connected by threads or snaps.

[0011] Furthermore, the bottom surface of the aluminum foil sealing bag has the same shape as the bottom surface of the box and its area is slightly larger than that of the bottom surface of the box, which facilitates a tight fit with the box after vacuuming.

[0012] Furthermore, the bottom surface of the aluminum foil sealed bag is fixed with a base, which makes it easy for the aluminum foil sealed bag to be kept in an open-facing position on the operating table, thus facilitating its placement into the holding unit.

[0013] Furthermore, the base is made of high-density cushioning material (such as rigid foam). After the container is wrapped in an aluminum foil sealed bag and placed inside the packaging box, this base can keep the container with the lid on top, reducing the impact of the box on the food.

[0014] Furthermore, after the aluminum foil sealed bag is vacuumed, a sealing sticker is affixed to the opening to prevent air leakage.

[0015] The advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model adopts a combined preservation packaging structure, which places cooked, additive-free Chinese fermented pasta with fillings into a sterilized, sealable container, then seals it with an aluminum foil bag and vacuum-seales it, and finally sterilizes it at high temperature. This utility model has the characteristics of simple structure, convenient operation and low cost of use. The pasta dough and fillings do not need to be added with any preservatives to extend their shelf life. In addition, it also saves transportation costs after being removed from cold chain transportation.

[0017] 2. This utility model helps to maintain the flavor and quality of freshly made pasta, and is easy to carry, easy to sell as a souvenir, and maintains the integrity of the pasta's shape (it will not be squeezed or deformed due to vacuuming, high temperature and high pressure, etc.). For fermented pasta, high temperature sterilization will not destroy the fermentation structure and flavor substances of the dough, allowing consumers to easily taste pasta that is close to freshly made. It has practicality and market competitiveness, and is of great significance to the market promotion and sales of Chinese fermented stuffed pasta, and can expand the sales scope of the product.

[0024] Example 1: See Appendix Figure 1 A preservation packaging structure for Chinese-style fermented filled pasta includes a pre-sterilized, sealable container unit and an aluminum foil sealing bag 3. The aluminum foil sealing bag 3 can completely contain the container unit and completely wrap the container unit after vacuum sealing. The container unit can hold at least one pasta dish. The container unit is a high-temperature resistant covered box 1 to facilitate sterilization by high-temperature steam. The box 1 is made of polypropylene plastic or bamboo tube and is used as disposable packaging. The box 1 is cylindrical in shape. A sealing ring 6 is provided inside the lid 2 of the box 1. The lid 2 is detachably connected to the main body of the box 1 by threads.

[0025] The bottom surface of the aluminum foil sealing bag 3 has the same shape as the bottom surface of the box body 1, but its area is slightly larger than that of the bottom surface of the box body 1, which facilitates a tight fit with the box body 1 after vacuuming. After vacuuming, the aluminum foil sealing bag 3 is sterilized at high temperature and then cooled to room temperature. By combining vacuuming and high-temperature sterilization with the aluminum foil sealing bag 3, the growth and reproduction of microorganisms can be effectively prevented, reducing the contact between the pasta and the external environment, thereby significantly extending the shelf life of the pasta.
