Frozen shrimps weigh 1/4 staff after defrosting: otherwise, how can they be cheaper?
"you really should go to the supermarket to look at frozen shrimps, half the shrimps half of the water." Recently, Ms. Xu broke the news hotline.
Ms Xu is a housewife who usually takes care of the family's daily life and is also a good cook. Two days ago, she bought a box of frozen shrimps from the supermarket. The price was not cheap, and the shrimp looked quite bright. But when she came home, she found that the frozen shrimps became "shrimp soup", and the shrimps after thawing were all soaked in the water. "The price of this ice is not cheap."
yesterday, the reporter went to the Century Lianhua, European, Huarun and other large supermarkets, to see frozen shrimps in freezer such as frozen water products. How much ice does this frozen shrimp take? The golden newspaper laboratory has done an experiment in this period.
market survey
frozen shrimps in frozen shrimps with the most frozen small yellow fish inside ice at least
yesterday, the reporter visited several large supermarkets. In the supermarket freezer, all kinds of frozen water products are packed neatly.
frozen aquatic products are divided into two categories, one is branded and the other is non branded bulk aquatic products. The price of the former is more expensive than that of the two. But look again, the ice in bulk frozen aquatic products is obvious.
the reporter took a package of frozen band fish and picked it up on the rest of the strip. The small portion of the ice that was attached to the strip fell on the bottom of the package, with the size of the fist together. In contrast, branded frozen products contain much less ice.
in addition, the frozen products with brand packaging indicate the net content, but most of the frozen aquatic products have information on the producer / supplier information, the date of scale, the date, the unit price, the weight and the total price, but it does not indicate the net content of the product, or the content of the ice.
"is this ice in the shrimp and the fish on top?" The reporter asked the staff of the supermarket. The staff told reporters that products like frozen shrimps were sold bundled with ice cream and shrimp.
but in Auchan supermarket, the reporter found that a frozen shrimps marked 30% of the ice on the price tag, and it does not seem to contain much ice.
several supermarkets, the reporter found that in several frozen aquatic products, frozen shrimps have the most ice content, frozen fish section contains a lot of ice, frozen small yellow fish inside the ice is the least.
reporter experiment
211.5 kg frozen shrimps thawing only 58 grams
yesterday morning, the reporter bought two boxes of frozen shrimps and a bag of frozen fish segments randomly from several supermarkets. After more than two hours of natural thawing, the ice in the shrimps has completely melted into water, with a little ice on the hairtail. Then, the reporters weighed one by one.
the first bag of shrimps weighs 194.5 grams, the unit price is 71.96 yuan /kg, the total price is 13.96 yuan, and is purchased from Huarun Wanjia supermarket. Before the thaw, each shrimp was covered with a layer of ice coat. In appearance, the frozen shrimps are glittering and translucent. However, at this time the shrimps became smaller, and they were all in the water. The reporter picked the shrimp out and weighed it. The box weighed 97.5 grams of water and the shrimp net weight was 97 grams. According to the net recalculation, the unit price of the shrimp should be 143.92 yuan /kg.
the weight of second bags of shrimps is 211.5 grams, the unit price is 35.60 yuan /kg, the total price is 7.26 yuan, and is purchased from the Lianhua supermarket. This box of shrimp is bigger than the smaller box, but the same is that the shrimp is covered with a thick ice coat. The shrimps singled out are weighed 153.5 grams and the weight of shrimp is only 58 grams. The price of shrimp is raised to 125.17 yuan /kg.
reporter bought the hairtail section is packed in transparent plastic bags, purchased from Century Lianhua supermarket.

industry,
fish "ice coat" said to keep fresh
in fact, it is short of
but a person in the aquaculture tells a reporter that many merchants will tell you that the package ice is for keeping fresh, except that it can make the aquatic products sell good looking, keep the product intact, and also to extend the water. The preservation time of the product, but in fact the ice content 20% or 90%, the effect is the same, "when it comes to keeping fresh, the time is long, the ice bag is too thick and things will deteriorate." So the more ice you pack, the more suspicious you are.
"the weight of the ice is counted in the total weight." Yesterday morning, when the reporters bought frozen shrimps at the supermarket, a staff member of the supermarket told reporters directly, "if there is no ice, how can the price be so cheap. Everyone sells it. "
yesterday afternoon, the reporter consulted the Ningbo Municipal Administration of market supervision on whether the ice content of frozen aquatic products was related. The staff told reporters that at present, they have grasped the fact that there is no uniform standard on ice content of frozen products. Although there is a standard for determining the net content of frozen aquatic products in the industry, this standard is not a national mandatory standard and cannot be used as a basis for law enforcement.
2013 October, China Fisheries circulation and processing association and the National Federation of industrial and Commercial Association of water industry chamber of Commerce issued a "ice limit order", the company's Frozen Shrimps products must not exceed the total weight of 20%. Two the association said that frozen cooked prawns overpack ice and infringe on consumers' interests.
staff of the Ningbo Municipal Administration of market supervision said that if consumers find that the actual net content of the frozen products has a large deviation from the net content indicated on the outer package, they can complain to the relevant departments.
