中国酒店餐饮中的食品营养问题研究

随着我国社会的不断进步,经济的不断发展,人民群众的生活水平逐渐提高,人民的生活节奏也越来越快,生活方式也逐渐发生改变.因为各方面原因,现在越来越多的人喜欢在外就餐,但是目前我国酒店餐饮中的食品依然存在营养问题,例如,酒店为了追求菜品的色香味,破坏了食物的营养,忽略了膳食平衡.为了人们的健康饮食,急需解决这些问题.本篇文章以中国酒店餐饮中的食品营养为例,对存在的问题进行深入分析,供大家参考.     

Cash cropping and food crop productivity: synergies or trade‐offs?

The case for promoting export‐oriented cash crops in Africa has generally been based on their direct potential contribution to agricultural productivity and small farmer incomes. A relatively neglected avenue of research concerns the synergistic effects that cash cropping can have on other household activities, including food production. The conventional view that cash crops compete with food crops for land and labour neglects the potential for cash crop schemes to make available inputs on credit, management training, and other resources that can contribute to food crop productivity, which might otherwise not be accessible to farmers if they did not participate in cash crop programs. This article builds on previous research by hypothesising key pathways by which cash crops may affect food crop activities and empirically measuring these effects using the case of cotton in Gokwe North District in Zimbabwe. Analysis is based on instrumental variable analysis of survey data on 430 rural households in 1996. Results indicate that—after controlling for household assets, education and locational differences—households engaging intensively in cotton production obtain higher grain yields than non‐cotton and marginal cotton producers. We also find evidence of regional spill‐over effects whereby commercialisation schemes induce second round investments in a particular area that provide benefits to all farmers in that region, regardless of whether they engage in that commercialisation scheme. The study suggests that the potential spill‐over benefits for food crops through participation in cash crop programs are important to consider in the development of strategies designed to intensify African food crop production.     

食品安全监管长效机制建构研究

近年来食品安全问题时有发生,食品安全已经成为关系国计民生的一个极为突出的社会问题。因此,加强食品安全监管的研究,建立和完善我国食品安全监督管理体系,实施有效的食品安全应对措施,具有极其重要的意义。本文分析了我国食品安全监管存在的问题,并在借鉴国际经验的基础上,提出几点政策建议：健全食品安全检验检测体系;加强食品安全教育体系建设;充分发挥消费者组织、行业协会的监督作用等。     

The negative spillover effect of food crises on restaurant firms: Did Jack in the Box really recover from an E. coli scare?

Despite the enormous impact of food crises on restaurants, limited understanding of their long-term impacts and associated factors has undermined crisis managers’ ability to handle crisis situations effectively. This article investigated the long-term impact of food crises on the financial performance of restaurant firms and identified the factors that influenced this impact. This explanatory study examined the case of Jack in the Box, whose 1993 Escherichia coli scare was the first and largest restaurant-associated food crisis in modern times. An event study method was used to uncover stock price movements of Jack in the Box, in conjunction with 73 unrelated food crises that occurred from 1994 to 2010. Stock prices of Jack in the Box exhibited significantly negative responses to other firms’ food crises, moreover, the negative spillover effect was stronger if the crisis occurred closer in time, was similar in nature, and was accompanied with no recall execution. These findings shed light on the long-term financial impact of food crises and offer insights for crisis managers to develop more effective crisis management strategies.     

The relationships between food-related personality traits,satisfaction, and loyalty among visitors attending food events and festivals

This study applies the concept of food-related personality traits to hospitality and tourism and identifies relationships between personality, satisfaction, and loyalty. An on-site survey was carried out with 335 visitors attending the Gwangju Kimchi (local food) Festival in South Korea between 15th and 19th of October, 2008. The relationships between 4 latent constructs (food neophobia, food involvement satisfaction, and loyalty) and 16 indicators were measured using structural equation modelling. The findings showed that food neophobia had a negative effect on satisfaction and loyalty, food involvement had a positive relationship with loyalty, and satisfaction and loyalty showed a significant positive relationship.     

Impact of hotel-restaurant image and quality of physical-environment,service, and food on satisfaction and intention

This study developed a theoretical framework in which overall image, image congruence, and quality of physical environment, service, and food affect guests’ satisfaction and intentions to revisit a luxury hotel restaurant and visit other restaurants of the same hotel by considering the influence of conspicuousness as a moderator. The measurement model assessment revealed that all items included an acceptable level of measurement quality. Results of the structural analysis indicated that the research variables were in general significantly associated; quality dimensions and satisfaction had a mediating role; and the impact of satisfaction and overall image on decision formation was greater than that of other variables. Moreover, the structural invariance model assessment indicated that conspicuousness acted as a significant moderator. Overall, our proposed theoretical framework was found to include a sufficient power in predicting patrons’ intentions for luxury hotel restaurant products. Using this quantitative approach, our research objectives were wholly achieved.     

Local poverty reduction in Chile and Mexico: The role of food manufacturing growth

This paper analyzes the relationship between local poverty and food manufacturing growth in Chile and Mexico using propensity score matching, differences in differences and spatial econometrics methods. We focus on food manufacturing as a sector with a number of characteristics that make it potentially pro-poor, and whose incentives for spatial distribution may either strengthen or dampen its poverty reduction potential. The overall results indicate growth in food manufacturing employment contributes to local poverty reduction.     

Construction and validation of a scale to measure tourist motivation to consume local food

Although the importance of the role of local food in tourism has begun to form an academic debate in the last decade, little effort has been invested in understanding what tourist motivations influence consumption of local food and beverages in a tourist destination and to develop a measurement scale for those motivations. Thus, this study adopted the comprehensive procedures of measurement scale development recommended by prior studies. The scale development procedure yielded a five factor measurement scale with acceptable levels of reliability and validity. Five underlying motivational dimensions of local food consumption were labelled: cultural experience; interpersonal relation; excitement; sensory appeal; and health concern. The outcomes and applications of the developed scale are discussed both in terms of theoretical and managerial implications.     

Does Participation in the Food Stamp Program Increase the Prevalence of Obesity and Health Care Spending?

We use panel data techniques and information on state-level Food Stamp Program characteristics to obtain unbiased estimates of the impact of Food Stamp Program participation on weight status and health care spending among nonelderly adults. Our results suggest that program participation by women leads to a 5.9% (p = 0.07) increase in their likelihood of overweight and obesity, which is smaller than previous estimates, and to higher medical expenditures. The direct effect of program participation on medical spending through higher discretionary income is significantly larger than the indirect effect through changes in weight status.     

Food price increases and net food importing countries: lessons from the recent past

Recent increases in food and other commodity prices have highlighted concerns that many poor countries are net food importers and higher food prices would worsen their trade balances. In this article, we analyze the changes in food trade balances associated with the 32% increase in food prices from 2000/2001 to 2004/2005. We find a small deterioration in food trade balances of low‐income countries and an improvement in middle‐income countries. The deterioration is most severe for countries in conflict and small island states, so attention should be placed first on these countries and on a few very‐low‐income countries that are also vulnerable. Because low‐income countries as a group had much lower agricultural GDP growth rates than middle‐income countries, the answers to food vulnerability in low‐income countries should probably be addressed within the context of incentives for agricultural production.
