Abstract: Before the Mid-Autumn Festival, mooncakes were the first to be sold. Xinhua News Agency's "Xinhua Viewpoint" reporter found that the shelf life of moon cakes with different brands and tastes ranges from 20 days to 120 days, and even the shelf life of moon cakes with the same taste may be several times different, which is puzzling ... It was very hot before the Mid-Autumn Festival. Xinhua News Agency's "Xinhua Viewpoint" reporter found that the shelf life of moon cakes with different brands and tastes ranges from 20 days to 120 days, and even the shelf life of moon cakes with the same taste may be several times different, which is puzzling. How many mysteries are there in the shelf life of moon cakes, who should manage the shelf life, and is there a gap in legal supervision? The reporter conducted an investigation on this. The shelf life of moon cakes varies greatly. Many mysteries lead to doubts. The reporter visited several supermarkets and found that the shelf life of moon cakes is really a difficult problem to explain clearly. To sum up, there are the following "mysteries": First, the shelf life of moon cakes with different tastes varies greatly. The reporter saw in the Wujiaochang store of Wal-Mart that the shelf life of red bean paste moon cakes in Maiyuan is 20 days, but the shelf life of sugar-free moon cakes in Guangdong Cuisine Square is 120 days. Many other brands of moon cakes have a shelf life ranging from 45 to 60 days. Second, even the same taste, the shelf life of different brands of moon cakes is quite different. For example, the shelf life of the ice-covered moon cake of Lao Zhou brand is 120 days, while the shelf life of the ice-covered ice cream of Maiyuan is only 40 days. The shelf life of sugar-free moon cakes in Guangdong Cuisine Square is 120 days, and the shelf life of sugar-free moon cakes in Sanniu is 90 days. The shelf life of bean paste moon cakes in Laoda factory and Zhenda is 45 days, and that of Maiyuan is 20 days. Third, the moon cakes of the same brand with different production dates have the same shelf life. Tesco supermarket reporter saw that although Kutokuhayashi's bulk moon cakes were produced on July 3 and July 26, the shelf life was written "Please eat before September 30". Fourth, the production dates of some brands do not meet the standards. Wang Guojun, a senior engineer of Shanghai Modern Food Studio, said that he had seen in Wal-Mart that the carton packaging of a famous brand of moon cakes was printed with the date of production, but the packaging in the box had no date of production at all. The survey found that mooncakes with the same taste and different brands have a shorter shelf life and a higher price. For example, for the sugar-free moon cakes mentioned above, the shelf life of Sanniu is 28.8 yuan per catty for 90 days, while the price of Cantonese restaurant is 22.8 yuan per catty for 120 days. This mystery of shelf life puzzles many consumers. "Preservative" is the secret of longevity of moon cakes, and what factors are related to the "hand-shaking method" of small enterprises, which makes consumers puzzled. Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety, College of Food Science, China Agricultural University, told the reporter that the shelf life has a certain relationship with processing technology, storage conditions and filling varieties. It is also related to the addition of preservatives, but it cannot be said that a long shelf life will definitely add more preservatives. "But how many preservatives are added is really one of the secrets of the longevity of moon cakes." Wang Guojun told reporters that large enterprises have strict control over preservatives, but many small manufacturers have lax supervision over additives, especially preservatives, and often use the "hand-shaking method" to add them. "That is to say, when the hand shakes, it will increase. Mooncakes with a shelf life of one month will not go bad in three months. When shopping in the supermarket, I saw that the moon cake had no deoxidizer, the manufacturer was unknown, the price was very cheap, the shelf life was very long, and there was probably a problem. " 20 1 1 after the implementation of the new standard for the use of food additives, many preservatives can no longer be used to add moon cakes. Wai Shum, general manager of Shanghai Xiangteli Food Development Co., Ltd. said, "In fact, technological progress can replace some preservatives. For example, we stopped buying lotus seed paste with bleaching powder a few years ago, and we also adopted the' external control method' in anticorrosion. That is, adding a deoxidizer to the package instead of adding a preservative directly to the moon cake. " According to industry insiders, in order to control the cost and extend the shelf life, manufacturers still add a lot of preservatives to keep the bulk moon cakes sold through grocery stores and even some supermarkets fresh. It is understood that an 80g moon cake packed with deoxidizer will cost 0.3 yuan more than that packed with preservative to 0.4 yuan. The length of the shelf life is "the enterprise has the final say". Managers of a number of food companies told reporters that the length of the shelf life is "the enterprise has the final say". People in the industry who have been engaged in the production of moon cakes for many years pointed out that the shelf life of ordinary moon cakes in the industry is currently "determined" to be two months, and most of them uniformly stipulate that all moon cakes produced at different times will expire on September 30. "This is because consumers are afraid of trouble after the time scale is long, and they can't sell it when the time scale is short, so it has become a' conventional practice'." Regarding the shelf life of food, there is a widely circulated "regulation" on the Internet. However, Wang Guojun told reporters that the State Light Industry Bureau has been revoked, and the shelf life of food in the planned economy era does have "national standard" regulations; However, after the liberalization of the market, different enterprises have different production conditions and processes, so it is difficult to unify the shelf life. These regulations have been abolished. The abolition of the regulations has given some small enterprises an opportunity. According to industry insiders, the standard practice is for enterprises to carry out various tests before the new products go on the market, and then carry out tests after a while, and finally scientifically determine the shelf life. However, many small enterprises will not do this, and some will bid for a few days, which is very casual. Zhenhua Gu, director of the US Food and Drug Administration, told reporters that the shelf life of food is currently controlled by enterprises themselves, and there is no mandatory regulation by the regulatory authorities; However, the regulatory authorities will conduct spot checks on some products near the shelf life to see if they still meet the due standards and have expired. According to industry insiders, the regulatory authorities rely too much on testing methods. For example, an additive for moon cakes, if not indicated in the ingredient list, is actually like looking for a needle in a haystack. "In daily supervision, quality supervision departments and other departments should pay attention to checking the raw material room and the purchase list of the enterprise at the same time, and compare whether the purchased and filed raw materials are different from the ingredient list, so as to ensure that additives will not become' fish escaping from the net'." & lt/SPAN>。 & lt/TD & gt；
