Have you ever paid attention to the aseptic packaging that can be seen everywhere around you?1. Overview of aseptic packaging
Aseptic packaging refers to packing the sterilized materials into pre-sterilized or aseptically treated packaging containers in a sterile state according to product requirements, and storing them in airtight, airtight In a specific environment that is ventilated or even opaque, it can be kept for a long period of time without refrigeration at room temperature without changing the quality.2. Internal structure of aseptic packaging
The internal structure of aseptic packaging has 7 layers, which are polyethylene, polymer, aluminum foil, polyethylene, base paper, ink, and polyethylene from the inside to the outside. Among them, base paper is the main carrier of aseptic packaging, which can stably support printing; polyethylene can prevent moisture and protect printed patterns; aluminum foil can prevent oxidation, block odors and avoid light.3. Application of aseptic packaging
Due to the above advantages of aseptic packaging, this technology has been widely used in the packaging of food, beverages, dairy products and edible oils, as well as beverages, condiments, medicines, cosmetics and other products.4. Types of aseptic packaging
★Completely sterile packaging
Completely aseptic packaging means that the liquid food is filled and packaged with aseptic packaging materials in a sterile environment after sterilization. There are many suitable products, such as:
Milk: UHT sterilization for 2-6 seconds at a temperature of 130-150°C.
Juice: The maximum heating temperature is within 100°C, it can be sterilized within a few seconds, and then cooled to 20°C for filling and packaging.
Semi-sterile packaging is a packaging method for solid foods that are difficult to completely sterilize, such as cakes, processed meat foods, etc., to suppress the initial bacterial count, and use aseptic packaging materials to fill and package in a sterile room, and then refrigerated and circulated. Suitable products are:
Cake: packed in air, stored at 15-18°C.
Processed meat products: vacuum packaging.5. Advantages of aseptic packaging
First, it can preserve the nutritional content of food in good condition;
Second, the composite packaging material and vacuum state can protect the product from the invasion of light, gas, peculiar smell and false organisms, and no refrigeration is required for transportation and storage;
The third is that the shape of aseptically packaged products is generally brick-shaped, with high space utilization and light weight, so the cost is not high;
Fourth, most of the packaging raw materials are paper, which is in line with environmental protection packaging;
Fifth, it is suitable for automatic continuous production, which saves labor and energy.6. Overview of current situation and market prospect forecast of aseptic packaging industry
