China on Sunday ordered the closure of nearly half the nation’s dairy companies in an attempt to clean up an industry blighted by scandal.

The General Administration of Quality Supervision, Inspection and Quarantine, says of over 1,100 dairies inspected, 426 failed to pass the licensing renewal test.

Another 107 were ordered to suspend production until they improved operations.

Fearing many dairy owners will ignore the production ban and secretly resume operations, officials also issued a warning. “Production without a license will be strictly punished according to the law,” the agency said.

Like other parts of China‘s food sector, the dairy industry has been riddled with poisoning Read more…

Future Of Food For 9 Billion? Edible Insects

Do you prefer the grasshopper to the ants? Are beetles tastier than grubs? 

Insects produce much smaller quantities of greenhouse gases per kilogram of meat than cattle and pigs. This is the conclusion of scientists at Wageningen University who have joined forces with government and industry to investigate whether the rearing of insects could contribute to more sustainable protein production. Insect meat could therefore form an alternative to more conventional types of meat.

Greenhouse gas production by insects

Cattle farming worldwide is a major producer of greenhouse gases. For the assessment of the sustainability of insect meat, the researchers at Wageningen University quantified the production of greenhouse gases of several edible insect species. The results of the study were published in the renowned online journal PLoS ONE on 29 December.

The research team has for the first time quantified the greenhouse gases produced per kilogram of insect product. The gases concerned were methane (CH4) and nitrous oxide (N2O). The results demonstrate that insects produce much smaller quantities of greenhouse gases than conventional livestock such as cattle and pigs. For example, a pig produces between ten and a hundred times as much greenhouse gases per kilogram compared with mealworms.

Emissions of ammonia (which causes the acidification and eutrophication of groundwater) also appear to be significantly lower. A pig produces between eight and twelve times as much ammonia per kilogram of growth compared to crickets, and up to fifty times more than locusts. An additional advantage of insects over mammals is that they convert their food into meat quicker.

Alternative
The study indicates that proteins originating from insects in principle form an environmentally-friendly alternative to proteins from meat originating from conventional livestock. Further research is required to ascertain whether the production of a kilogram of insect protein is also more environmentally friendly than conventional animal protein when the entire production chain is taken into account.
