Abstract: A new way about scientometrics method used in studying the strategy and layout of standard system is put forward. Firstly, the standard information has been analyzed and then their characters are obtained through CSSN, which becomes the basis of successfully analyzing the standard layout. Secondly, the character information of standards are searched by the intelligence means of scientometrics and literature searching, which is used for studying the strategy and distribution of standards. Taking solar technology standards of China and Japan as an example, quantity comparing of standards, time distribution, standard products, standards of different technology fields and so on are analyzed. The results show that analyzing the solar standard system through scientometrics method can supply the direction for the national strategy development and for increasing the industry competition.

• Cassava juice showed high levels of cyanogenic glycosides (CNGs) • A significant difference of CNGs among cultivars was found. • Dietary intake of cyanide not posing chronic risk to Chinese consumers but acute risk. • The MRL of CNGs was proposed as 200 mg/kg in cassava. • Cyanide risk assessment should be based on CNGs quantification rather than CN– The intake of cassava would probably induce adverse health effects since there are toxic cyanide in cassava. However, the risk assessment of cassava consumption has not been reported in China. Therefore, this paper aimed to evaluate the dietary risks of cassava cyanide and proposed a maximum residue limit (MRL) for cyanogenic glycosides (CNGs) in cassava. The retention rate of CNGs and CN– were 61% and 11% after boiling, respectively. The acute dietary exposure of CN– and CNGs were 0.6-fold and 1.7-fold of acute risk reference dose, respectively. There was no chronic health risk across all populations concerning cassava consumption. The MRL of CNGs was proposed as 200 mg/kg in cassava. Risk assessment of cyanide for foods rich in CNGs was suggested to be based on CNGs quantification rather than that of CN–. [ABSTRACT FROM AUTHOR]

• Phenolic acids intake of Chinese residents have been assessed for the first time. • 16 phenolic acids in 116 foods from five regions of China were determined. • Free, esterified and bound phenolic acids were determined. • The dietary intake of food refers to the data of 2009–2013 and 2002. Phenolic acids have been reported to have many biological activities, but daily intake information is scarce. In this study, the phenolic acid contents of 116 commonly consumed food in five regions of China (Beijing, Hangzhou, Wuhan, Chongqing and Guangzhou) were analyzed by high performance liquid chromatography-mass spectrometry (HPLC-MS) and dietary intakes estimated. Tea had the highest total phenolic acids (TPA) content in all regions investigated. Phenolic acids were in esterified and bound forms, and hydroxycinnamic acids accounted for more than half of TPA content, except in tea and legumes. Average TPA intake was 193.50 mg/ day at the national level but ranged from 157.09 to 263.01 mg/ day among the regions. Rice, tea, and fruits were the main contributors to dietary intakes of TPA. Also, TPA intake in the period 2009–2013 increased 31.65 mg/ day compared with 2002, largely due to increased intakes of fruits, vegetables, and legumes. [ABSTRACT FROM AUTHOR]
