How long is the shelf life of canned food?

(Summary description)The production date of canned food refers to the date after the raw materials have been processed, canned, sealed, sterilized, cooled or aseptically filled, and passed the commercial aseptic evaluation of canned food. Food shelf life refers to the period during which the quality of prepackaged food is maintained under the storage conditions indicated on the label. During this period, the product is fully suitable for sale and maintains the unique quality that is not required or has been stated on the label.

Qiu Kai, Deputy Secretary-General of the Canned Subcommittee of the National Food Industry Standardization Technical Committee, explained that the shelf life of food is a promise made by the manufacturer to consumers. During this period, all sensory indicators (such as color, aroma, taste, Form), physical and chemical indicators (such as soluble solids-sugar content, solids), and food safety indicators (such as heavy metals, lead, arsenic, tin, and microorganisms) are all in compliance with the product standards.

　　How long is the shelf life of various canned foods? Qiu Kai said that canned foods are foods with a long shelf life because they have achieved commercial sterility, not because of the addition of preservatives. The shelf life of canned food is composed of two elements, one is the storage condition, and the other is the period. The two are closely related and inseparable. The storage conditions must be indicated on the food label, which usually include room temperature, dark storage, refrigerated storage, and frozen storage. If the storage conditions of the product do not meet the regulations, the shelf life of the food is likely to be shortened, or even loss of safety guarantee.

Canned food can be stored at room temperature. Under normal storage and transportation conditions, according to the main products claimed by the company, canned meat and canned aquatic animals are generally no less than 24 months; canned fruits and vegetables are generally no less than 15 months ; Canned food such as deep-fried dried fruit, fruit juice, shrimp, shellfish, crab, tomato sauce, etc. is generally not shorter than 12 months. Canned food production enterprises can determine the shelf life by themselves according to specific conditions such as production varieties, technical conditions and packaging containers. Qiu Kai advises consumers to buy more canned foods in metal packaging according to their consumption capacity, because it has the best barrier properties and creates the safest coat for canned foods.

What factors affect the characteristics of the stainless steel chain conveyor belt? [ 2020-10-09 ]

As an important mechanical basic part for the supporting and maintenance of various electromechanical products, the stainless steel chain conveyor belt has the advantages of low friction, easy start, rapid rise, compact structure, and high level of "three modernizations" (standardization, serialization, and generalization) , Adapt to the requirements of modern machinery, long service life and easy maintenance and other characteristics, its function, level and quality have a direct impact on the accuracy and performance of the conveyor. It is widely used in various fields of the national economy. With the continuous development of our country’s transportation industry, the current mesh belts have made great progress in terms of scale, number, or technology. However, compared with the technology of advanced countries, they still have great progress. There are many shortcomings, especially when it comes to the strength of the mesh belt, China’s technology has great difficulty to break through. 　　 The strength check of the stainless steel chain conveyor belt in the design is generally based on the large static tension during operation, in the form of selection of the safety factor, and then the influence of other factors is included. The main influencing factors of mesh belt strength are as follows. (1) Static tension Static tension is the guarantee of the tension that the mesh belt does not run randomly. When the inner tension of the mesh belt is the same, the tensile stress caused by the static tension is evenly distributed on the cross section of the stainless steel chain conveyor mesh belt, following the movement of the mesh belt Will produce alternating tensile stress, which is the basis for selecting the belt strength. (2) The dynamic tension is the braking of the mesh belt. The braking process is a very stable process. The speed, acceleration, tension and disturbance of each particle have dynamic characteristics and are a function of time. This dynamic feature has little effect on small conveyors, but it has a great impact on large conveyors. The dynamic tension generated by this kind of undisturbed working conditions may greatly exceed the static tension, and sometimes even reach the static tension. Many times. When an emergency brake occurs, the consequences will be severe, which can easily cause insufficient strength of the conveyor belt and cause belt breakage. But after adopting the soft start device, the dynamic tension can be reduced to less than 30 of the static tension. (3) Additional stress The additional stress of the stainless steel mesh belt includes the bending stress that bypasses each drum, the additional stress through the transition section, the additional stress generated by the bending section and the horizontal bending section in the vertical plane. As long as the diameter of the roller, the spacing and shape of the transition roller, and the radius of the curved section of the stainless steel chain conveyor belt are correctly selected in the engineering design, these additional stresses can be greatly reduced. In addition, when the radius of the driving drum changes due to manufacturing errors or coal powder, it will also cause the redistribution of the mesh belt stress.

What materials are commonly used in food packaging? What are their characteristics? [ 2020-05-24 ]

In our lives, we may not have noticed all kinds of food packaging. The materials and characteristics of these food packaging are very particular. So what materials are commonly used in food packaging? What kind of characteristics does it have? Let's understand together: Food packaging generally uses the following materials: 1. Plastic packaging Plastic packaging materials have high-quality characteristics such as chemical inertness, insoluble, strong and toughness, and their raw materials are rich in sources, low in cost, and excellent in performance, but their stability is not good, they are not resistant to high temperatures, easy to deform, and improper handling will cause environmental pollution. There are also some hygienic problems for certain foods, so the scope of its use is limited to a certain extent. However, plastic packaging materials are still gradually replacing traditional packaging materials such as paper and glass, and are one of the most important packaging materials in food packaging. 2. Metal packaging Metal packaging materials and containers are made of thin metal plates or foils, which are processed into various forms of containers to package food. Because metal packaging materials have high-quality characteristics such as light-proof, high barrier properties, high and low temperature resistance, shock resistance, fall resistance, and recyclability, they are more and more widely used in food packaging and become one of the four most important modern packaging materials. . However, metal packaging materials have poor chemical stability and are not resistant to acids and alkalis, especially when they are used to package highly acidic foods, they are easily corroded, which affects the flavor of the food, which limits its scope of use to a certain extent. 3. Glass packaging At present, the amount of glass used in my country accounts for about 10% of the total packaging materials, especially one of the important materials in food packaging. Glass packaging materials have high-quality features such as high sealing, high transparency, corrosion resistance, and easy forming. However, glass containers are heavy and easy to break. It is this performance disadvantage that affects its use and development in food packaging. Especially impacted by plastics and composite packaging materials. However, glass materials are still widely used in food packaging due to their unique high-quality characteristics that other materials cannot replace. From the above common food packaging materials, we can conclude that food packaging needs to have high-quality characteristics such as airtightness, corrosion resistance, light-proofing, high and low temperature resistance, shock resistance and drop resistance, but no packaging material can have all of them. These properties, therefore, should be determined according to the food packaged when choosing food packaging.
