肉制品中亚硝酸盐状况分析及快检技术研究进展探析

在当前肉制品加工过程中,亚硝酸盐是非常常见的一种添加剂。亚硝酸盐虽然能够让肉制品保持良好的色泽,避免出现异味,具有抑制细菌和防腐的作用,但摄入过多的亚硝酸盐将会给人体健康造成严重危害。亚硝酸盐含量超标在近几年肉制品检测中较为常见,且肉制品中的亚硝酸盐在细菌的作用下,在加工过程中也会发生变化,所以采取快检技术进行肉制品中亚硝酸盐含量分析,对保证肉制品安全具有重要作用。本文具体分析了肉制品中的亚硝酸盐含量状况和快检技术,避免因亚硝酸盐超标而诱发肉食品安全问题。     

浅谈肉制品的包装与保存

Market segmentation of fresh meat shoppers in Taiwan

Fresh meat product retailing at traditional markets in Taiwan causes concerns over meat safety issues.The agricultural administration has established programmes to raise consumer awareness of potential risks of fresh meat that have remained at room temperature for several hours. Although supermarkets sell chilled and frozen meat products, the majority of grocery shoppers in Taiwan still prefer purchasing fresh meat products at traditional markets where meat is displayed on counters or hung on hooks. This study utilizes survey data to segment meat shoppers in Taiwan. Results indicate the shoppers who purchase meat products at supermarkets tend to continue shopping at that location. Potential shoppers of supermarkets, who may switch from traditional markets to supermarkets for meat products, are identified and the major concerns of this group are the meat safety issues. Factors that influence the possibilities of selecting supermarkets for meat products are examined.     

新疆主要肉类产品之间的价格波动关联分析

基于2001年~2017年新疆4种主要肉类产品价格时间序列数据,采用VAR模型和脉冲响应方法,分析了猪肉、牛肉、羊肉和鸡肉之间的价格波动关系以及相互影响程度,结果表明:2001年~2017年新疆各肉类产品价格均呈上涨趋势,其中2017年牛肉、羊肉价格与猪肉和鸡肉价格比较上涨幅度更大;短期内,各肉类产品受自身价格波动影响显著,长期内,牛肉、猪肉价格波动是引致新疆肉类产品市场价格波动的主要因子;从价格波动传导机制上看,猪肉和牛肉二者互为彼此价格波动的影响因素;鸡肉价格相对独立,不受其他肉类产品价格影响;羊肉价格受到猪肉、牛肉价格的影响较显著,但羊肉价格波动对猪肉、牛肉价格的影响有限。通过保证猪、牛产业规模化发展,保护扶持羊产业,鼓励发展鸡产业,建立新疆主要肉类市场价格联动的监测预警机制等措施,可以增加新疆肉类产品有效供给,降低肉类产品价格波动,保障新疆主要肉产品供需平衡。     

Socioeconomic Effects of Reducing Household Carbon Footprints Through Meat Consumption Taxes

Beef and sheep products represent the largest emitters of greenhouse gases within the meat group. One way of encouraging Scottish households to substitute purchasing lower carbon footprint meat products such as chicken is through a carbon consumption tax. In this article, the effects of such a tax were studied using a dynamic per capita error correction version of the almost ideal demand system (AIDS). The data used in the analysis were from a Scottish household panel dataset for the years 2006–2011, which allowed disaggregation by three socioeconomic groups. The results suggest that the net application of meat taxes is likely to reduce demand for beef and sheep products irrespective of socioeconomic group. Application of all meat carbon consumption taxes has the potential to reduce household demand for meat products, resulting in a likely 10.5% reduction in Scottish meat emissions.     

Demand Analysis of Meat in Malaysia

One distinct change in Malaysians' food consumption behavior has been the preference toward meat products. Thus it is meaningful to gain insight of meat consumption patterns. As the market becomes increasingly market-led, information on current meat consumption patterns is required to assess how they are likely to change as prices and incomes change. This study attempts to provide a better understanding of demand for meat products in Malaysia. By utilizing data from Household Expenditure Survey 2004/2005, Engel curve analysis was conducted to derive income elasticities of meat products from QUAIDS model. The estimated income elasticities show that current food consumption patterns are showing signs of convergence toward a Western diet, exhibiting tendency for preference toward red meats (mutton and beef) over white meats (poultry and pork). The estimated elastic own-price elasticities indicate that Malaysian consumers are sensitive to the change in prices of the meat products, with other things remain constant.     

A review of the ‘consumer interest’ in organic meat

The study aims to provide a critical review of the literature on the consumer interest in the UK in organic food, with a particular focus on organic meat. Given that people are more likely to purchase products if they have faith in them, the regulation of organic food standards is reviewed to explore issues affecting consumers. This is followed by a review of the organic meat sector. Aspects of the consumer interest considered in this paper include consumer information, consumer access, consumer safety, consumer choice and consumer representation. As the literature on organic food/meat in the UK is extensive, it was therefore necessary to be selective with regard to the publications suitable for this review. Most of the literature selected for this paper has been drawn from UK publications, although several European and international sources have also been used. The review found that there is a considerable level of interest in the UK organic meat sector. As the regulation of organic food produced is set at varying standards across the European Union, this could lead to consumers being misled regarding the quality of products offered. It was also found that, although consumers perceive organic foods as healthier, more nutritious and tasting better than non‐organic products, the literature shows that this may have only a limited basis on fact. Contamination of organic products with pesticides and even genetically modified ingredients is always possible. Organic farmers are permitted to use other ingredients in organic meat products that may be harmful to health. Escherichia coli and Salmonella risks associated with conventional meat also appear to affect organic meat. Consumers need clear, accurate and reliable information about organic meat. They also need to be provided with safe products, a choice of organic products, access to organic products and to be represented effectively.
