Abstract:The tightening policy of market regulation for food ingredients and novel foods produced by genetically modified microorganisms has hindered the development of the bio-economy. Here, the comparative studies have been conducted on the market regulations of food ingredients and novel foods produced by biomanufacturing in EU, USA, Japan, and China. These countries are all very concerned about the regulation of food ingredients and novel foods from biomanufacturing, however, they adopt quite different polices. EU is cautious, USA is positive, and Japan is less cautious. Over the past decades, China has been tightening the approval of food ingredients and novel foods produced by genetically modified microorganisms. At present, the whole world is actively responding to the supervision and access of new food ingredients and foods produced by new technologies. It is suggested that a positive application and approval path should be established, unified, and simplified for promoting the marketing of new products in China.
