面粉添加剂溴酸钾的危害及替代品研究

溴酸钾是我国近期规定禁用的一种面粉添加剂。主要用于面包生产的溴酸钾,就是一个从曾经广泛使用到严格限制,直至被逐渐禁止使用的例子。本文综述了溴酸钾的用途和危害,介绍了用碘滴定法(AACC48-42)、阴离子交换-电化学检测法检测溴酸钾的方法,侧重介绍了溴酸钾的替代品及其发展前景。     

正确认识食品添加剂的作用及危害

食品添加剂是一类为改善食品色、香、味等品质,以及为防腐、保鲜和加工工艺的需要,而加入食品中的化学合成或者天然物质。目前,我国食品添加剂有23个品种,种类达2000种左右。本文综述了我国食品添加剂的种类和它们在食品工业方面的主要作用,以及违法使用非食品添加剂,超限量、超范围使用食品添加剂等现象带来的危害。

谈过量使用面粉增白剂的危害

进入九十年代以来,面粉增白剂普追应用于全国各面粉厂家,给面粉工业带来了一次小小的革命,面粉色泽一下子比以前白了许多。但正如任何事物都是一分为二的那样,面粉增白剂有其利的一面──它确实能够增加面粉的白度满足用户的消费心理;但也有其弊的一面──最近几年,一些面粉生产厂家,特别是个体小机组,不按国家规定的添加量（300Ppm）使用增白剂,一味追求面粉的白度,超剂量使用,对面粉质量造成了一定影响,同时对人民的身体健康也带来了一些危害。要了解面粉增白剂的危害,首先应搞清楚它的化学成分和漂白机理。1面粉增白剂的化…     

食品添加剂过量的危害

合理使用食品添加剂,对于丰富食品生产和促进人体健康都有好处。但也必须看到,食品添加剂毕竟不是食品的天然成分,如使用不当,或添加剂本身混入一些有害成分,可能会对人体健康带来一定危害。     

面粉添加剂在专用小麦粉生产中的重要作用

<正> 1 面粉添加剂在专用小麦粉生产中发挥积极作用 面粉添加剂泛指用在面粉中的各种食品添加剂,其种类很多。实际上,面粉添加剂是一种行业称谓,主要是指用在面粉中的那些添加剂,其实在食品添加剂中并没有一类专门叫做面粉添加剂的。这些添加剂,可以添加在面粉中,也可以添加在食品中,在哪里添加更合理、更经济、更有效还值得研究。原先面粉厂是不使用添加剂的,主要是食品厂使用。面粉厂使用添加剂后,给食品厂及其他面粉用户带来一定的便利,但会不会出现重复使用的问题,这应该引起重视。

Organizational harm,legal condemnation and stakeholder retaliation: A typology,research agenda and application

The essence of the ethical issues pertinent to business activities is the harm or benefit that occurs as part of a company's resource transformation process. A typology is developed that sorts ethical issues according to three variables: (1) the nature of the harm, (2) the nature of those harmed and (3) the transformation stage where the harm occurs. Propositions are formulated that would enable analysts and practitioners to predict the degree of legal condemnation of, and stakeholder retaliation to, harms generated by questionable moral reasoning. An organizational harm analysis is then constructed as a decision making tool that could supplement cost/benefit analysis.Denis Collins is a Doctoral Candidate at the Katz Graduate School of Business of the University of Pittsburgh and a Research Associate with the BG Productivity and Gainsharing Institute. He has published several articles in the areas of business ethics, social philosophy and participatory management.     

Sharing product harm information: The effects of self-construal and self-relevance

Product harm information spreading in the marketplace may have profound consequences for companies, public policy makers and consumer well-being. However, limited research is available on what makes consumers share such information with others. This paper examines how self-relevance and self-construal affect the sharing of product harm information and the underlying processes that shape sharing. Five experiments demonstrate that under independent self-construal, highly self-relevant product harm information is less likely to be shared. The reluctance to share highly self-relevant information is attenuated under interdependent self-construal. The differential effects of self-construal are related to self-serving processes and motivations for sharing product harm information with others. The results apply to the sharing of negative information, but not positive information. Companies may use these findings to manage the diffusion of product harm information.

Foreign travel and the risk of harm

Systematic data on the risk of fatal and non-fatal injury from external causes to those who travel abroad for purposes of business or pleasure are seldom recorded and are consequently hard to come by. In this paper, the risk of fatal injuries to foreign travellers using historical and newly acquired data from national databases is estimated. Overall, it appears from these data that the risk of fatal injury to foreign travellers lies in the range of 20 to 90 per 100 000 person-years of exposure for many destinations worldwide, although different rates may pertain in selected situations where special conditions apply, for example, where there is heavy participation in risky sports or increased driving. This level of fatal injury risk is not noticeably different from that of staying in one's home country if one lives in a Western-style industrial country, although the types of hazards responsible may vary in type and proportion. With increasing levels of travel, and the growing popularity of more adventurous pursuits, it is possible that risks could be increasing in this sector.
