食醋按生产工艺不同可分为酿造食醋和配制食醋,配制食醋是以食用冰醋酸,添加水,酸味剂,调味料,香辛料,食用色素勾兑而成,仅具有一定的调味功用;而酿造食醋是以粮食为原料,通过微生物发酵酿造而成,其营养价值和香醇味远远超过配制食醋,具有调味,保健,药用,医用等多种功效。 相似文献

北京王致和食品集团的前身是北京市金狮食品酿造公司,该公司原下辖北京市王致和腐乳厂、北京市酱油厂、北京市龙门醋厂等七家国有企业.改制前,其实行的是两级法人体制,即总公司是法人,下属各厂也是法人,由于整体不能形成合力一致对外,导致该公司的主营产品酱油、食醋销量连续下滑.为了扭转这种局势,2000年1月,经过缜密考虑,他们在原北京市金狮食品酿造公司的基础上重新组建了北京王致和食品集团. 相似文献

近些年来各国政府和组织更加重视农产品质量安全追溯体系的建设,发达国家相继对出口到当地的农产品作出的可追溯性要求,凸显了中国农产品质量安全追溯体系的出口贸易效应。本文在梳理相关研究文献和总结国内外农产品追溯体系实施现状的基础上,添加"是否可追溯"这一变量,运用扩张后的贸易引力模型,利用1992-2010年我国农产品主要出口数据,就中国农产品追溯体系实施的贸易效应进行实证检验。研究发现,欧盟、美国和日本等主要进口国家和地区的追溯性要求对中国农产品的出口产生了积极的贸易促进效应,根据这一实证结论提出,应该从政府支持和消费者认可两个方面采取措施,推动中国农产品质量安全追溯体系建设。 相似文献

进口B2C跨境电商商品质量风险的有效评估是实现高质量监管的基础。文章基于进口B2C跨境电商活动全流程监管,对涉及商品质量的境外采购、仓储物流、平台销售、商品售后四个环节进行风险分析,构建了包括风险识别、评估指标体系、风险度量、风险等级划分以及风险原因追溯五个部分的进口B2C跨境电商商品质量风险评估系统,并以杭州市进口B2C跨境电商企业为例,进行实证研究。研究结果表明,杭州市进口B2C跨境电商企业的风险点主要集中于供应商资源、商品溯源、售后保障、商品质量标准认知四个方面,且不同规模企业的商品质量风险存在异质性。据此对企业和政府提出了相关政策建议。 相似文献

The introduction of improved food traceability systems has aimed to restore consumer confidence in food safety and quality, in part by being able to provide consumers with more information about the origins of foods and food ingredients. However, little is known about consumers' opinions and beliefs associated with traceability, nor their preferences for information provision. In the current paper, consumer information needs and requirements regarding traceability are investigated. Semi‐structured interviews with consumers in four European countries focused on the need for traceability, the preferred means of communication, labelling and bodies held responsible for traceability and dealing with fraud. Results show that there is a clear consumer need for varied information about food and the production processes involved. Rigorous and accountable traceability systems may assist in making such information available to consumers. 相似文献

Traceability systems are becoming an important tool for tracking, monitoring and managing product flows through food supply chains. Traceability can be used as a method of certifying production, processing and nutritional credence attributes of food products. Environmentally sustainable production is a credence attribute that is gaining in importance in the eyes of consumers. In this research, the importance of traceability in verifying environmentally sustainable production practices is examined. The data were collected in online surveys related to consumer's perceptions and concerns about food safety, trust and reported behaviour related to meat consumption in three countries – Canada, the US and Japan. Determinants of traceability in verifying environmentally sustainable production practices include respondents' locus of control about food safety, food purchasing characteristics such as whether they normally buy organic products or shop at supermarkets and general traits such as worry and trust. In comparing across countries, there are significant differences in the interests in traceability to verify environmentally sustainable production practices and in the determinants of level of importance ascribed. 相似文献
