But it is still science which is the most important element in decision-making for food risks analysis.
For example, for the determination of the CCP, we use the tool "tree of decision" whose elaboration is made thanks to a set of questions related to every risk and to every stage of the process, including the reception and the processing of raw materials [8].
· Ameliorate the working conditions using ergonomics and studies about the medium hygiene. · Limit the costs by the actions of energy and raw material saving
· Decrease raw material consumptions by the amelioration of food consumption systems and fight against all kinds of waste.

Material and Methods Collection and authentication of the plant material - Fresh leaves of Anredera cordifolia (Ten.)
Then, vacuum rotary evaporator and water bath was used to evaporate the solvent until the extract became desiccate.[16][17][18] Drugs and reagents like Carbopol, hydroxypropilmethylcellulose (HPMC), triethanolamine (TEA), glycerin, nipagin (methyl paraben), nipasol (propyl paraben), and distilled water were employed in formulating the Binahong leaves extract gel.[4][17][19] All of the materials were of pharmaceutical grade.
All statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS), version 21 (IBM® Inc, New York, USA). 3.

Evaluation Method on Energy Consumption and Carbon Emission for Public Building Yu Li1,a, Liang Yuan1,2,b,Zehong Li1,c,Yuanyuan Shi1,d and Shifeng Li1,3,e 1Institute of Geographic Sciences and Natural Resources Research, Beijing, China 2University of Chinese Academy of Sciences, Beijing, China 3China Agricultural University, Beijing, China aliy@igsnrr.ac.cn, bliangcrystal@126.com, clizehong@igsnrr.ac.cn, d312648345@qq.com, elsf_68@126.com Keywords: Energy Consumption, Carbon Emission, Public Building Abstract.
Broad building energy consumption comes from the entire building life cycle, including architectural design, building materials, transportation, construction, building operation, building maintenance and building processing. 
To this maybe added, considering the influence of building materials, retaining structure and climate for building energy consumption, energy consumption models on energy efficiency evaluation for building design scheme, such as foreign mature commercial software DOE - 2, EnergyPlus, eQUEST, etc have made good progresses these years.
