Packaging structure and making and packaging process for baked food

Abstract

The invention discloses a packaging structure and making and packaging process for baked food. The packaging structure is made from a high-density polyethylene special-paper planar sheet through a flashing method. The making and packaging process for the baked food is mainly characterized in that the baked food stands until the temperature of the baked food is lower than 100 DEG C, then the bakedfood is placed into an opening of the packaging structure made from the high-density polyethylene special-paper planar sheet through the flashing method, and then the opening is closed. According to the packaging structure and making and packaging process for the baked food, the cooling step in an existing baked food processing process is omitted, the processing time of the baked food is shortened, and the processing efficiency is improved; the packaging structure is made from the high-density polyethylene special-paper planar sheet through the flashing method, so that the situation that the food is contaminated by bacteria or other substances in the cooling process is avoided; no drying agent is added in the packaging process, so that the costs of a cooling chamber and drying agents are saved, the safety of the good is improved, the production capacity is improved, and the food cooling time and space are saved.

Description

technical field [0001] The invention relates to the technical field of baked food packaging, in particular to a baked food packaging structure and a production and packaging process of baked food. Background technique [0002] As we all know, baking, also known as baking and baking, refers to the process of dehydrating, drying and hardening materials by means of dry heat under the ignition of materials. Baking is an indispensable step in the production of bread and cake products. After baking After a series of chemical changes such as gelatinization and protein denaturation of starch, bread and cakes can be ripened, and the taste of food can also be changed. [0003] Food packaging is an integral part of food commodities. It protects food and prevents damage from biological, chemical, and physical external factors during the circulation of food from the factory to consumers. It can also maintain the stable quality of the food itself. It not only facilitates the consumption ...

Problems solved by technology

[0004] After the baked food is removed from the mold, it needs to be cooled before the subsequent wrapping or packaging of the product. The existing cooling method is to place the baked food baking pan taken out of the oven on the trolley for natural cooling or Push it together with the trolley into the cooling room for accelerated cooling. Natural cooling takes a long time to wait, and during the cooling process, bacteria are likely to be generated and food is likely to be polluted. Although accelerated cooling can reduce the cooling time, frequent Entering and exiting the cooling room will cause the loss of cold air, which will increase the production cost. At the same time, cooling in the cooling room will also produce bacteria and easily pollute food

Furthermore, baked goods need to occupy relatively more space when cooling, resulting in a waste of space

[0005] Due to the special fresh-keeping and moisture-proof requirements of baked foods such as biscuits, bread, and cakes, the material structure of the packaging materials is usually a two-layer composite film based on polypropylene, and a desiccant is added to the packaging bag during packaging. To avoid the problem of solvent residue, it is easy to cause secondary pollution to food and produce peculiar smell, which is not conducive to food safety. The addition of desiccant also has certain safety hazards
