Segmentation of Retail Food Store Formats in Qingdao, China

This study empirically estimates a multivariate binary choice model for four categories of food shopping store formats. The results indicate that in the Qingdao market, traditional counter parts such as wet markets and small grocery stores have been dominated by supermarkets and hypermarkets. At the same time, the rapid growth of hypermarkets in Qingdao is significantly challenging current supermarkets in this city, but they do not compete extensively with wet markets and small grocery stores. Further development of various categories of the food shopping store format is linked to store owned characteristics, potential interrelations among existing retail formats, as well as consumers' demographics and shopping habits.Food retail store format, consumer choice, multivariate probit model, China, Agribusiness,

Functional Foods in the Marketplace: Willingness to Pay for Apples Enriched with Antioxidants

The attention on so-called functional foods has been growing as consumers become more concerned with diet and nutrition. This article aims to measure consumers response to apples with naturally enriched antioxidant coatings. Surveys were conducted in grocery stores in Seattle, Washington and Spokane, Washington. The results suggest that consumers have a somewhat positive attitude towards functional foods in general and with apples enriched with antioxidants in particular. A contingent valuation technique was used to assess factors affecting consumers willingness to pay for the apples with antioxidant coatings. Consumers in the Spokane grocery stores are more likely to pay a premium for the new type of apples than consumers in Seattle. Consumers who look for a wide variety of product in choosing where to shop for food are more likely to pay a premium for apples enriched with antioxidants. Also, it is estimated that consumers, on average, are willing to pay from 4% to 8% premium for these apples.functional food, willingness to pay, antioxidants, Demand and Price Analysis, Health Economics and Policy,

Fluid milk consumption in urban Qingdao, China

This study relates the social-demographic characteristics of urban Chinese consumers to their consumption of fluid milk. A Tobit model is estimated drawing on individual consumer survey data collected in urban Qingdao in China in 2005. The major results of this study indicate that fluid milk consumption in urban Qingdao is much higher compared to China’s national level. The effect of increased income on milk consumption is positive, as expected. The expansion of modern food retailers also appears to play a positive role by facilitating consumers’ fluid milk consumption and influencing their food shopping patterns. The young and old consume significantly more fluid milk than the middle-aged. Health consciousness of the elderly and the openness of youth to new foods appear to be fuelling these consumption patterns. If the findings of this study apply to other urban regions in China, then as urbanisation continues so also will the trend of increasing fluid milk consumption in China.China, fluid milk consumption, market participation, Qingdao, Food Consumption/Nutrition/Food Safety,

WESTERNIZATION IN CHINA: A CASE STUDY IN PROCESSED POTATOES

Keywords: China, potatoes, westernization, food demand, convenience foods Abstract: The demand for convenience foods is growing around the world, especially in China. However, the contributing factors of this change in food preferences are still largely unknown. To measure this westernization trend, data from a survey of Chinese consumers in Beijing is evaluated using a multinomial ordered logit model to determine which consumer attributes influence the probability of consuming western foods such as French fries, mashed potatoes, and potato chips. Results show that higher income levels and positive opinions concerning western food taste have a significant influence on increased consumption of all three processed potato products. Additionally, younger ages and female gender were highly significant indicators of increased French fry and potato chip consumption.Crop Production/Industries,

U.S. Grass-Fed Beef: Marketing Health Benefits

Grass-fed beef is a product with health benefits that may appeal to health-conscious consumers. This article analyzes the results of a choice experiment to explore the importance of health benefits in the marketing of grass fed beef. Both price and fat and calories have a negative effect on the choice of the product, and higher levels of omega-3 fatty acids have a positive effect. Price is the most important attribute to respondents (39.5%), a low level of fat and calories is the second most important attribute (36.9%), and the level of omega-3 fatty acids is the least important of these factors (23.6%).Livestock Production/Industries, Marketing,

Consumer Response to Genetically Modified Food Products in Japan

In Japan, a large U.S. export market, there has been growing public opposition against genetically modified (GM) foods. Using a dichotomous choice contingent valuation method, findings show the discount needed for Japanese Seikyou consumers to purchase GM food products is positively affected (i.e., a greater discount is required) by higher levels of self-reported risk perceptions toward GM food, higher levels of concern about food safety and the environment, higher self-reported knowledge about biotechnology, education levels, and income. Interestingly, gender does not significantly affect the discount needed for GM food. Further, it can be inferred from the results that a transformation of Japanese consumers' perceptions and attitudes is needed for GM food products to successfully enter the Japanese market.Consumer/Household Economics,

Design of a high efficiency cyclone for collection of rare and low concentration airborne pathogens

Recent serious outbreaks of pathogens such as Chalara Fraxinea, (Ash Dieback) demonstrate the vulnerability of UK’s forests, woods, and trees. Early detection of threats is critical in the fight against such tree pests and pathogens. This requires a process for collecting and analysing the spores which is robust, flexible and can be deployed rapidly, but which also has sufficient sensitivity to detect the earliest precursors. The work presented here describes a newly-developed high-efficiency detection apparatus and is part of an ongoing BBRSC project to improve the UK’s biosecurity. Our automatic spore system is capable of collecting and analysing Chalara Fraxinea using a novel cyclonic pathogen collector. Cyclones are an effective way to separate small particles (spores) from large quantities of surrounding air and store them for analysis. Our system incorporates a purpose-designed high efficiency cyclone directly integrated with a low power custom impeller to maximise volumetric air sampling while minimising the power requirement. 3D printing was used extensively to validate theoretical models and the particle collection and retention capability of this series of prototypes was evaluated experimentally within our Aerosol test chamber. We found that we could collect greater than 90% of particulate in the target size range, thus providing a front-end to a detection platform. Our system is capable of operating autonomously and at low power, with a high sensitivity to ambient particles. The final system design incorporates the use of multiple cyclone storage vessels ensuring complete isolation of each sample, eradicating cross-contamination, and facilitating automated handling of the sample inside the same apparatus. COTS – commercial off the shelf components were incorporated into the cyclone to make a series of cost effective collection vessels. Early collection and detection of pathogens in-situ represents a considerable advance in surveillance and monitoring of pathogens strengthening UK biosecurity for the future

Development of an automated smart trap for wheat pathogens

National surveys show fungicide use on wheat continues to increase despite fluctuations in disease pressure, reaching a 30 year high in 2012 (Defra). Septoria tritici is the most significant foliar disease in UK wheat causing between £43M to £53M in yield losses annually; Yellow and brown rust are more sporadic but have caused significant losses during high disease years. In all cases control is by fungicide application costing £82M annually (GFK Kynetec 2013). Effective disease management relies on either prophylactic pesticide use or significant manual intervention and time consuming assessment of crop disease indicators by farmers and agronomists. Furthermore indications are that current levels of pesticide use could lead to increased risk of pesticide resistance, if this should occur it is estimated that wheat yields could reduce by up to 20%. To address this we have developed a prototype integrated and automated spore detection system, designed for unattended field application, to monitor and identify the presence of Septoria, brown and yellow rust. The prototype system incorporates novel cyclonic pathogen collection, on-board sample processing and isothermal DNA amplification chemistry (LAMP). We present the engineering design, optimisation and evaluation of our prototype system reporting on successfully completed laboratory testing and initial field trial results. This prototype will be the basis for the development of a commercially available system which, in addition to inoculum detection, will be capable of providing growers/agronomists with real-time information on inoculum moving into a crop enabling more effective timing and selection of fungicide application, and thus better control, increased yield, and improved environmental stewardship
