我国进出口食品化妆品风险预警概况 总被引:1,自引:0,他引:1
1.引言“风险”是指某种特定危险事件(事故或意外事件)发生的可能性和后果的组合“;风险预警”中的“警”是指事物发展过程中出现的极不正常的情况,也就是可能导致风险的情况,亦称“警情”。所谓“风险预警”,就是对那些可能出现的、极为不正常的情况或风险进行的测度,预报不正常情况或风险的时空范围和危害程度,以及提出的防范措施。它是检验检疫宏观调控的基本环节,是技术性贸易措施的重要组成部分,在世界主要国家和我国都备受关注。2.国外的风险预警系统世界主要贸易国家为了更好地调节和平衡国际贸易,保护本国市场,促进自身经济发展,都… 相似文献

我国食品进出口贸易中的农(兽)药残留问题 总被引:1,自引:0,他引:1
我国是食品与农产品出口大国,在国家职能部门的高度重视下,我国食品和农产品出口安全控制措施正趋于完善,逐步打破了某些进口国的技术壁垒,但是面临发达国家不断出现的技术性贸易保护措施,食品和农产品出口总体形势仍不容乐观,甚至相当严峻。国家质检总局李长江局长在近期召开的促进食品和农产品出口现场会上指出,目前我国食品和农产品出口仍面临国外技术壁垒强化、监管环节薄弱、疫情和农(兽)药残留、出口企业水平低、检验检疫工作不完善五大制约因素。特别是农(兽)药残留问题仍然严重。近年来,造成我国出口食品和农产品出口屡屡受阻的主要… 相似文献

This study highlights some important aspects of the package, such as packaging materials suitable for high‐pressure treatments, package properties (barriers and flexibility) and package integrity. Six different types of package were tested. They consist of multilayer plastic packages (PA/PE), where thickness, permeability and stress varied at yield point and at breakage. They achieve a good heat seal and good protection from the pressure medium (water) surrounding them. Experiments were carried out at 200, 350 and 500 MPa for 30 min at ambient temperature, comparing the performance of pressurized multilayer plastic packages with untreated packages. Different simulants (water, 3% acetic acid, 15% ethyl alcohol and olive oil), in contact with the packages, were used to demonstrate the good integrity between package and foodstuff during treatment and shelf‐life.

滴定法测定食品中亚硝酸盐含量的研究 总被引:1,自引:0,他引:1
亚硝酸盐含量的测定是食品检测中重要的检测指标之一,现行的检测方法很多。文中采用了滴定法测定食品中亚硝酸盐含量,利用亚硝酸根在酸性条件下跟碘离子反应,生成碘单质,再用硫代硫酸钠滴定法碘单质,间接测定食品中亚硝酸盐的含量。实验中还研究了淀粉用量、不同酸性物质和不同pH等反应条件对回收率的影响。最后研究了此方法测定亚硝酸盐含量的时,食品中其他物质对结果的影响。该方法测亚硝酸盐含量相对偏差为2.4%,限检量为0.30mg/kg。 相似文献

Biofuels are the current promising alternative to fossil fuels. However, the fluctuating food prices caused by oil price led to critics to biofuels. The paper surveyed biofuels production and grain production and consumption demand, and come to the concolusion that there was a little impact of corn ethanol on international food price, and there was no impact on China’s food prices. China has launched non-food biofuels development strategy to use marginal lands for growing hard crops, such as sweet sorghum, tuber crops, and switchgrass etc to produce biofuels without any impact on food security in the future. 相似文献

Packaging has the potential to reduce food waste and contribute to the United Nations sustainable development goal 12.3. Yet packaging is also a household food waste (FW) driver, necessitating packaging improvements. Through a review of primary consumer studies on household FW and packaging published 2006–2020, this study mapped the effects of packaging functions on different food categories to identify packaging-related FW drivers, solutions and research opportunities. Relevant studies are increasing, yet packaging yields less attention than factors including domestic routines. Many studies limit packaging discussion to the aspects attributed to wasted food, with date-labels and overly large pack sizes the most mentioned. Suggested solutions by extant literature include clearer date-labels and more pack size variety. However, research showing the effectiveness of these suggested solutions in households is lacking. Packaging formats and materials may affect packaging functionality and therefore household FW, but studies are lacking. There is therefore scope for household studies to collect more packaging related FW data. In particular, focussing on the effects of specific packaging functions on domestic food practices, with an effort to gather food-group-specific data. More studies in Africa, Asia, the Americas, Middle East and the Pacific/Oceania will provide insights beyond the current Eurocentric focus. These findings contribute to theory and practice within the focus of household FW and packaging literature, helping to extend existing research to support the development and implementation of packaging that considers regional differences in food systems, food routines and preferences for a better chance at reducing FW. 相似文献
