应用生物技术开发新的食品

所谓新的食品,它必须具备三个要素:一是营养价值高,既具有淀粉、脂肪、蛋白质等必须能量,又有一定的维生素和矿物质等,当然,某一种食品不能达到人体所需的所有营养物质,但新的食品应尽可能地使其具有较高的营养价值,让人们从似药非药的那些所谓“保健品”的误区走出来;二是无残毒、无劣变、无副作用(简称“三无”)绿色食品;三是方便食用。随着经济趋于全球化,市场竞争日益激烈,越来越多的人既希望从厨房走出来,又不为营养不全而犯愁。这就必须致力于开发营养价值高、又符合“三无”的方便食品,逐步实现生活社会化。开发新的食品,既是满足人…

Exploring the Impact of Customer Satisfaction on Food Retailers' Evolution: Managerial Lessons From Austria

Many studies have shown that customer satisfaction affects customer behavior and loyalty. There are, however, relatively few studies that examine the impact of customer satisfaction on store repatronage behavior by store-type choice. This study examines why Austrian consumers choose a certain store type (i.e., supermarket or bakery) for purchases in a particular product category (i.e., baked goods). Moreover, it assesses the impact of customer satisfaction on customer loyalty (i.e., the repatronage intention). The study found that customers valued different attributes for each store type. It also suggested that customer satisfaction and customers' intention to recommend varied by store type. Additionally, the bakery customers' tendency to spend more is positively related to their satisfaction level. Managerial implications for both types of stores are provided.     

What If You Stop and Think About It? Nutrition Logos and Product Selection Behavior

This study explores the effect of a health involvement manipulation on food choices and how food choices are influenced by front-of-pack nutrition labels. The results show that without health involvement, choice was significantly affected by both nutrition labels and product type, but the product choice with health involvement was affected only by whether the product was selected as the healthier one in the involvement manipulation stage. Moreover, selection of the healthiest product during the manipulation stage was affected by the product type but not the front-of-pack (FOP) labels, potentially because participants relied on their own knowledge or the product perception to assess the healthiness of the product rather than the label information. The implication is that consumers seem to behave differently when pushed into a “choose healthy” state of mind, and their reliance on label information to assess product healthiness may be product and context dependent.     

A Hedonic Analysis of Nutrition and Health Claims on Fruit Beverage Products

This paper investigates the effects on prices of nutrition and health claims for foodstuffs, in addition to other attributes, using fruit beverages as a case study. The model estimation is based on revealed purchasing behaviour for fruit beverages in the north‐east of Italy. Applying an hedonic price model, the price of a product is explained as a function of product attributes. The model estimate identifies the implicit retail‐market‐level price of specific attributes such as nutrition and health claims, ceteris paribus. Nutrition and health claims significantly affect retail prices. Our findings suggest that retail price response to nutrition and health claims differs in relation to other product attributes, showing a strong reduction of price variation among flavours when such benefits are claimed on the label.     

推广浮性饲料 发展低碳渔业经济

为实现渔业生态健康养殖,我们通过投喂浮性饲料与其它类型饲料效果对比试验,一是分别用国家绿色食品中心认证的通威“141”浮性饲料,代替冰鲜鱼投喂南方鲇等肉食性鱼类;二是在水库网箱分别用通威152浮性饲料与101沉性颗粒料投喂草鱼。实践证明：投喂浮性饲料,既满足鱼类最佳营养需要,又缩短养殖周期、降低饲料系数、降低养殖成本,实现节能减排、防治养殖水域内源性污染,确保渔业安全。由此可见大力推广绿色浮性饲料养鱼,有利于改善养殖生态环境,促进低碳渔业经济健康发展。     

Information and consumer willingness to pay for biofortified yellow cassava: evidence from experimental auctions in Nigeria

In this article, we use the Becker‐DeGroot‐Marschak mechanism to estimate consumer demand for biofortified yellow cassava varieties in two states of Nigeria: Imo in the southeast and Oyo in the southwest. These two states exhibit distinct habitual product color preferences for staple food made with cassava. We estimate the effect of nutrition information campaigns and nature of planting material delivery institutions on consumer demand. Willingness to pay estimations account for the effect of product endowment, censoring in bids and nonpayment. In Oyo, consumers are willing to pay a premium for light yellow cassava variety even in the absence of nutrition information. The article finds that nutrition information results in a large and significant price premium for biofortified cassava in both states, and the nature of delivery institution has no significant effect.     

Do Nutrition Claims Matter to Consumers? An Empirical Analysis Considering European Requirements

EU Regulation 1924/2006 introduced a European legal framework for nutrition messages for food product labels. The study analyses consumer interest towards nutrition labelling and claims, and examines the information consumers consider important during their purchasing decisions, and the main characteristics of those consumers interested in nutrition claims and nutrition labelling use. A total of 1,025 northern Italian consumers were surveyed. We estimate one binary logit model to investigate the use of nutrition labelling, and seven other ordinal regression models to analyse consumer interest towards nutrition claims and labelling. Consumers who use nutrition labelling have characteristics different from those who use nutrition claims. Consumers using nutrition labelling show a marked interest in food safety concerns, use experts as their source of information and have specific dietary habits. For consumers concerned about nutrition claims, the survey shows significant links with attributes influencing purchasing behaviour, such as price, brand, certification, etc. Socio‐demographic characteristics are statistically significant and show a positive link with age, gender and a negative linkage with income.     

The nutrition transition and agricultural transformation: a Preston curve approach

The nutrition transition in diets and health is closely tied to other aspects of economic development, including agricultural transformation and urbanization as well as demographic change and epidemiological transition from infectious to noncommunicable disease. Over time, dietary patterns typically shift from widespread inadequacy of many foods and nutrients, especially for children and mothers, into surplus energy intake and rising obesity with continued inadequacy of healthier foods. Diet‐related diseases remain the largest single cause of premature death and disability in all regions. This article combines food availability and dietary intake data from more than 100 countries over 30 years with a wide range of other evidence to characterize the nutrition transition and its association with changes in agricultural production and the food environment, asking how future dietary patterns might be steered toward healthier outcomes as national incomes grow.
