a (small) thing of weight and mass

More than three-fourths of the honey sold in U.S. grocery stores isn’t exactly what the bees produce, according to testing done exclusively for Food Safety News.

The results show that the pollen frequently has been filtered out of products labeled “honey.” The removal of these microscopic particles from deep within a flower would make the nectar flunk the quality standards set by most of the world’s food safety agencies.

Ultra filtering is a high-tech procedure where honey is heated, sometimes watered down and then forced at high pressure through extremely small filters to remove pollen, which is the only foolproof sign identifying the source of the honey. It is a spin-off of a technique refined by the Chinese, who have illegally dumped tons of their honey - some containing illegal antibiotics - on the U.S. market for years.
