Experts reminded the selection of dates not to pick red, it is the season of fresh dates, Hangzhou, at least 'consumes' about 30 tons of fresh dates.
Recently, some residents of Hangzhou have been puzzled to find that the fresh dates they buy are very attractive, but only a few days later, the dates are rotted; some dates have been eaten, even the skin is not sweet...
Are these phenomena normal and have they been made?
Yesterday, our reporter randomly purchased 4 dates from the market, and asked experts from Zhejiang University’s Orchard Research Institute for identification.
The phenomenon of the date bought was rotted every other day. 'Buy it before leaving it alone for a day. The dates are actually rotten! ' Yesterday, Zheng aunt shocked the morning newspaper and called for help.
Aunt Cheng lived in Xiasha and bought a pound of jujube on a stall last Thursday. On the first day of buying home, Aunt Cheng and her family savored it. The skin of the date was sweet, but the inside of the jujube was frivolous.
Aunt Cheng’s son said skeptically: “Online is saying that the dates in Henan are soaked with saccharin. This is not the date that saccharin soaked! 'My son suggested mother to throw away for health.
15 yuan a pound of dates, Zheng aunt could not throw.
The next night, she was ready to take it out for herself. When I opened it, many dates had already been rotted. Just put one day, how can it be so bad? Aunt Cheng is very puzzled.
Mr. Li, who lives in the Jiangnan Nan Xiaoxiao Community, has doubts about the date. Yesterday, Mr. Li bought a fresh jujube on a stall in South Xiaoyue, and especially picked the red one to buy home. When I went home to eat, the dates were a bit sweet and bitter. It tastes like the taste of sweetener that I had eaten as a child. 'Mr. Lee said.
The date that saccharin was soaked with water is prone to rot. The reporter took questions from Mr. Aunt Yi and Mr. Li to Professor Ye Minger of the Institute of Fruit Science at Zhejiang University. Prof. Ye is an expert on the date.
As soon as they heard about their experiences, Professor Yee smiled and said that he had encountered it. A few days ago, he went to a friend's house to make a guest. His friend put a date on the plate. The date was a look and the color was red and brilliant. At that time, I told them that there may be problems with this date, or do not eat well. '
'The jujube's skin is sweet and the jujube's flesh is pale, it may be saccharin water. 'Professor Yip explained that the processed dates are easily rotted due to cell aging.
In fact, the state explicitly prohibits the addition of saccharin.
'The regular consumption of sodium saccharin and sodium cyclamate in foods with excessive levels will cause damage to the liver and nervous system, especially to the elderly, pregnant women and children, and may cause cancer in the long term. '
Investigation of 4 parts of randomly bought date two may have problems. Yesterday, the reporter made a random investigation.
Yesterday, the reporter randomly bought a large-scale supermarket on the Jianguo North Road in Hangzhou, a fruit supermarket on the Stadium Road, a small fruit shop near the Dao Mao Lane community, and a small fruit shop on the north road around the city. They purchased a kilogram of dates respectively.
Ye Ye, who studies the jujube, arrived at the morning post yesterday afternoon and helped identify it on the spot. In the end, Prof. Ye confirmed that the reporter randomly selected 4 dates, two of which were suspected to have problems.
Let's take a look at the identification of two dates that may have problems.
Situation 1: The dates purchased by a large supermarket are red and rotten. It is estimated that the medicine was soaked in the large-scale supermarket to purchase the 'Golden Silk Date', the price is 13.03 yuan, and the date printed on the box is August 20, 2011. Looking through the closed transparent plastic box, many dates are red and bright, and the colors are very beautiful.
Prof. Yee opened the banding on the plastic box and sifted and picked it up. Some of the red-coloured dates were pinched and soft patches. Several red dates had already given off white mold.
'It is estimated that the medicine may have been soaked after harvesting. Just 10 days before packaging, the natural red dates will not rot so quickly, and they will not be corrupted. '
What medicine was used in the end? Professor Ye Minger said that this can only be confirmed after laboratory tests. In general, some unscrupulous merchants will soak dates with a ripening agent based on ethephon, making the color of the dates bright red, or soaking with saccharin water to increase the sweetness of the dates and attract consumers. buy.
Situation 2: A date purchased by a small fruit shop is another 'problem date' of 'Li Gui' winter jujube. The reporter bought a small fruit shop near the community of Dao Mao Lane.
At the time of purchase, the salesperson of the fruit shop pointed to the big green date with a price of 20 yuan a pound. The tone was definitely said: 'It is a winter jujube, produced in Shandong. '
Ye Minger took out a few of the 'Dongzao' and carefully looked at the light. Although it is large and looks like a jujube, it is actually not a real jujube. '
The reason is: the jujube's skin is smooth, and this 'Li Guidong jujube', the rough and bumpy skin, apparently unworthy of name.
At least 30 tons of fresh dates are eaten in Hangzhou. Today, Shandong's winter date has not been listed in large quantities. Since the supply of jujube on the market in Hangzhou is relatively small, and it is a seasonal commodity, the current wholesale price of dates is as high as 20 yuan per catty.
Of course, most date dates in Hangzhou are not a problem.
Industry insiders said: 'The general formal market will be strictly controlled and will not allow problems to come in. But it does not rule out the problem of date through some other channels into some markets in Hangzhou. '
Judging from the market, the people in Hangzhou love to eat dates. The reporter learned from the Hangzhou Fruit Wholesale Co., Ltd. (Market) that supermarkets and fruit stores in Hangzhou consume at least 30 tons of dates each day.
Why the problem date will flow into Hangzhou? Analysis of the industry believes that the current high price of dates, the market has demand, some unscrupulous traders, depending on profits, purchase poor quality dates after processing 'beauty' in order to obtain profits.
Professor Ye Minger and other scholars believe that the emergence of problem dates also reflects the problems of consumer perceptions in Hangzhou and needs to be changed.
'Many people think that red dates are good and red ones are mature. In order to meet the needs of consumers and attract consumers to purchase, unscrupulous businesses may deal with the green jujube and redeem 'beauty'. Professor Yeh suggested that consumers should learn to distinguish the characteristics of fruits that are truly natural and mature.
Reminding you to choose dates, do not pick Professor Hongye reminded, open-weather cultivation of winter jujube, normal maturity, the appearance of a light reddish-brown on the side of the skin of the sun, and some skin often appears slightly yellow.
After several days of normal dates, there will be folds in the epidermis. The flesh will not be so easily rotten. The most water will be lost and the bite will be very dry. If it is refrigerated, the preservation time can be longer.
However, if it is a date that has been treated with various methods such as potion, the cells of the date are destroyed, and they are particularly susceptible to rot.
For fresh dates, farmers usually pick and market when their dates are blue. If the date body is red and purple is red, it is best not to buy it.
Sweet dates, such as the saccharin, which is soaked in saccharin, will have a bitter taste. After washing with water, the sweetness will be significantly reduced. If the sweet flesh is not sweet, be alert.
News link Henan found the soaking sweet nectar of the jujube at the end of August this year, Henan has media exposure, Henan processing plant will be placed in the sweet saccharin, saccharin into the water, soak for half an hour and then out after an hour The dates will become red and sweet.
The company that added the cyclamate said that sweet, red-colored dates are so good that they do it.
