Consumers' Perception and Evaluation of Fresh Cut Buying Attributes: A Survey on the Italian Market

Abstract

During the last twenty years, consumer choice in high income countries is no longer merely dictated by price and the organoleptic characteristics of a product, but also by other features some of which are not patently tangible. The growing importance of such attributes in the process of consumer choice is not only due to income increase, but also to changes in lifestyle such as migrations from the countryside, a generalized urbanization and consequential city life style, female emancipation and work outside the domestic walls for women, the drastic decrease in hard physical labor and the process of internationalization. The present survey study aims to explore the importance that Italian consumers give to fresh cut buying attributes and which of these attributes should be taken into consideration by industries in order to satisfy the needs of the most critical shoppers. Where possible, market and survey data for fresh cut products will be compared with those for cooked products and before presenting the results and conclusions of the study, the technical issues of processing will be highlighted owing to the fact that they affect the marketing of these products, the recent market situation with regard to consumption will be illustrated and the methodology used will be described.     

耕作制度发展矛盾及其对策

建国50年来，我国的耕作制度发生了翻天覆地的变化，耕作制度的改革有了新的起点与突破，仅以占全世界7％的耕地养活了占全世界22％的人口。然而，在取得了举世瞩目的成就的同时，耕作制度也面临突出的矛盾和严峻的挑战。对此，从耕作制度的发展趋势看，应采取积极对策，保证农业的持续稳定发展。

Small producers,supermarkets, and the role of intermediaries in Turkey's fresh fruit and vegetable market

A wide range of empirical studies show the extent to which the rise of supermarkets in developing countries transforms domestic marketing channels. In many countries, the exclusion of small producers from so‐called dynamic marketing channels (that is, remunerative ones) has become a concern. Based on data collected in Turkey in 2007 at the producer and the wholesale market levels, we show that intermediaries are important to understanding the impact of downstream restructuring (supermarkets) on upstream decisions (producers). Results show first that producers are not aware of the final buyer of their produce, because intermediaries hinder the visibility of the marketing channel, thereby restricting a producer's choice to that of the first intermediary. Econometric results show that producers who are indirectly linked to the supermarkets are more sensitive to their requirements in terms of quality and packaging than to the price premia compensating the effort made to meet standards. Therefore, the results lead us to question the role of the wholesale market agents who act as a buffer in the chain and protect small producers from negative shocks, but who stop positive shocks as well, and thereby reduce incentives.     

Normative,authentic, and altruistic fruit and vegetable consumption as weblog discourses

The Internet is a growing information and communication channel for health- and diet-related issues. Keeping updated on the fruit- and vegetable-related (F&V) discourses among laypeople is important for health communicators in order to promote F&V consumption through tailored health messages. The aim of the present study was to identify F&V-related discourses in weblogs that were maintained, obviously, to influence diet. A theoretically chosen sample of weblogs were analysed applying critical discourse analysis. The analysis showed three partly overlapping F&V-related discourses: (1) normative consumption with a focus on single nutrients and physiological mechanisms; (2) authentic consumption with a desire for naturalness; and (3) altruistic consumption where ethical responsibilities are enhanced. Bloggers have clear perceptions on ideal F&V consumption, but it is a challenge for the reader to make a synthesis of the discourses presented. Filtering contradictory instructions requires health literacy, which may need more support from dietetic professionals.
