With the increase of information provided to consumers on the outer packaging of goods, consumers have higher and higher requirements for consumers' ability to distinguish and understand various information. What is the difference between shelf life and shelf life?
today, people pay more and more attention to the quality of goods, The storage period of various commodities has also become a topic of concern to consumers. When Ms. Wang, a consumer, bought sugar in the supermarket, she found that the outer package of sugar said that the shelf life was 18 months and the shelf life was 24 months. Ms. Wang was puzzled. She didn't know whether she should finish eating within the shelf life or within the shelf life with the increasing market demand. There are really many consumers like Ms. Wang who are not clear about the shelf life and shelf life
the marking of the date is very different.
when visiting several large supermarkets in the city, I found that at present, most foods are basically marked with the shelf life, which ranges from a few days to a few years. In contrast, only a small proportion of foods are marked with shelf life. However, foods with both storage and shelf life dates are even rarer. In addition, some snacks such as potato chips and candies are not marked with these two dates, but the automaker is not satisfied with this, but is printed with the words "best to eat before a certain date". Items such as disposable water cups and detergents are marked with shelf life. For example, the storage period of disposable water cups is 2 years, the storage period of fresh-keeping bags is 5 years, and the storage period of detergent is 2 to 3 years
it is difficult for consumers to distinguish between shelf-life and preservation
is there any difference between shelf-life and shelf-life? Miss Zhou raised such a question. She told that she only glanced at the production date and food raw materials when buying goods, and never paid attention to whether the shelf life or shelf life was written on the product package. Among the more than ten consumers interviewed later, most of them could not distinguish between quality assurance and preservation. A consumer said that he paid special attention to these labels because he was worried about buying products that were about to expire or expired, but he never understood the difference between the shelf life and the shelf life. He thought that as long as he ate them before these dates, he would have no problem, and never thought about the difference between words. Some consumers said that they generally care about the shelf life of food, but they don't pay much attention to the shelf life of other items. For example, for daily necessities such as toothpicks and disposable water cups, sometimes when buying drinks, disposable paper cups will be attached. Most consumers will not care about the shelf life of paper cups, thinking that paper cups have no shelf life
different concepts of quality preservation
what are the differences between the two dates? According to the Municipal Bureau of quality and technical supervision, the shelf life refers to the best edible period and the shortest applicable date. That is, within this period, the product is completely suitable for sale, and the sensory characteristics, physical characteristics, nutritional components and safety of the food meet the product standards. Beyond the time limit specified on the food label, some sensory characteristics of food, such as color, aroma and taste, may change, but they still meet the health standards and can be eaten within a certain period of time. The shelf life refers to the recommended last eating date. It refers to the final consumption period after storage according to the conditions specified on the food label (temperature, humidity, cool, dry). Beyond the final consumption period, the sensory characteristics, physical characteristics, nutritional components and safety of food may no longer meet the requirements of product standards, or even mildew and deterioration. The composition of food is complex, so it is difficult to determine a strict and accurate storage period. It is generally determined based on years of experience and storage experiments, so it is the recommended final consumption period
the difference between shelf life and shelf life is so different. In addition, experts also remind consumers that when buying various foods, they should not only see whether the manufacturer marks the shelf life or shelf life, but also observe whether the sales environment meets the storage requirements. Because there are many conditions attached to the storage of many foods, such as cold storage, dark protection, cool and dry storage, if the conditions specified on the label are not met, even if the food does not exceed the shelf life or shelf life, it may have deteriorated
