BEIJING, April 24 (Xinhua) -- The Chinese government has ordered food companies to keep clear and intact records of all their production and selling operations as part of the efforts to prevent the illegal use of food additives.All food manufacturing and management companies must examine all products in stock for any trace of illegal food additives and keep records of the results in accordance with laws and regulations, according to a circular released Sunday by the food safety committee under the State Council, or China's Cabinet.The circular came days after Vice Premier Li Keqiang warned of the great harm from illegal additives in food, promising "a firm attitude, iron-hand measures and more efforts" in dealing with the problem.Companies that fail to keep genuine and intact records and documents will be ordered to reform, and those providing fake records and certificates will be suspended from operations and punished accordingly, said the circular.According to the circular, it is strictly forbidden to produce and sell non-edible materials that are likely to be used in food production without official certificates, and authorized production companies of these materials must adopt a real-name selling system.These materials, including those banned in animal feed and drinking water, should not be sold to food and feed companies, the circular added.A series of food safety scandals emerged in China recently. In one of the latest cases, steamed buns in Shanghai were reported, last week, to have been dyed, sold past their expiration date, or laced with coloring additives to mislead consumers.

NEW YORK, May 27 (Xinhua) -- U.S. stocks expanded gains on Friday ahead of the long Memorial Day weekend as surging commodity prices overcame disappointing economic data.European Central Bank Governing Council member George Provopoulos said that Greece might deal with its debt problem if it sticks to the aid program. That comment, which was considered as bullish by investors, drove the U.S. dollar weaker and led commodity prices surge on Friday.The stock market was driven by higher commodities prices, with thin trading volume ahead of the Memorial Day holiday, despite somewhat disappointing economic data on Friday.The Commerce Department said that both personal income and spending rose 0.4 percent in April, in line with market estimates. However, the rise in spending was the smallest in three months, suggesting the consumption situation was still weak.Meanwhile, pending home sales dropped 11.6 percent in April. The reading was a seven-month low. The market expectation was a drop of 1 percent.Moreover, the Thomson Reuters/University of Michigan Consumer Sentiment index came in above analysts' estimates. Concerns about higher gas prices and inflation had knocked the gauge down in March and April.Despite those disappointing data, analysts still held a bullish view toward the stock market. "Despite our near-term caution, we continue to see the S&P 500 reaching 1400 over the coming year," Alec Young, equity strategist of S&P Equity Research told Xinhua.According to Alex, while recent macro headwinds were raising questions about the sustainability of recent earnings momentum, he still believed that a downside trend of market was fairly limited and that the current weakness is more likely to be a correction, rather than the beginning of a new bear market."In our view, 2011 estimated EPS would have to be excessively optimistic to justify a bear market,"he added.The Dow Jones industrial average added 38.82 points, or 0.31 percent, to 12,441.58. The Standard & Poor's 500 was up 5.41 points, or 0.41 percent, to 1,331.10. The Nasdaq Composite Index rose 13.94 points, or 0.50 percent, to 2,796.86.

WELLINGTON, May 27 (Xinhua) -- Eating kiwifruit might be a much better way of getting vitamin C into your system than taking purified vitamin supplements, according to research from New Zealand.Researchers with the University of Otago found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form.The study was published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research, said a statement from the university.Lead researcher Associate Professor Margreet Vissers said people required vitamin C (ascorbate) in all body tissues and organs to be healthy, but the only source of vitamin C was through food or in purified form, arguably the most commonly consumed vitamin supplement.In the experiment vitamin C-deficient mice were fed the vitamin over a month, either as kiwifruit or as an equivalent amount of pure vitamin C, said the statement.Mice fed the kiwifruit absorbed vitamin C much more efficiently than those given the purified supplement form, and they also retained it for longer, indicating something in the fruit improved absorption and retention."The findings of the mouse trial have important implications for human nutrition," said Vissers."The question that has often been asked is whether a supplement is as good a source of vitamin C as whole foods, but few studies have addressed this issue. We are uniquely placed to do that work. "An equivalent human study was underway to determine whether the situation also applied to people, said the statement.The mouse study was funded by the university and kiwifruit marketing firm Zespri.
