Insects or not insects? Dilemmas or attraction for young generations : A case in Italy
Cavallo, Carla ; Materia, Valentina C. - \ 2018
International Journal on Food System Dynamics 9 (2018)3. - ISSN 1869-6945 - p. 226 - 239.
Consumers' acceptance - Insects as food - Millennials

The production of proteins from insects is the next big challenge for Western countries. Although several benefits have been highlighted, mainly regarding their high environmental, social and economic sustainability, the use of insect-based ingredients is a radical break with tradition and encounters a very low acceptance among consumers. In this study, we present an exploratory analysis on a sample of Italian Millennials to test whether some product attributes can represent a barrier or a driver to such consumption. Results suggest that acceptance is far to be obtained, although the most powerful driver to insect consumption can be the invisibility of the insect shape.

Visual elements of packaging shaping healthiness evaluations of consumers : The case of olive oil
Cavallo, Carla ; Piqueras-Fiszman, Betina - \ 2017
Journal of Sensory Studies 32 (2017)1. - ISSN 0887-8250
Visual elements of food products can play an important role in determining food choice through shaping the attributes perception of consumers. Symbols and logos have the role of conveying information, but they can be interpreted in different ways. The product used as a case study is Extra-Virgin Olive Oil. The elements tested are: color of the bottle, sensory quality claims, organic production logos, country of origin (COO), and cold processing. An online questionnaire was completed by a sample of Dutch and Italian consumers in order to have cross-national results. Consumers' healthiness perception toward packaging alternatives with combinations of these elements were related to consumer traits through a contingent ranking method. Healthiness perception was enhanced by elements on the label such as: organic production, COO and by traits of the consumers such as familiarity and sustainability concern; while it was lowered by sensory indications of pungent properties. Somewhat unexpectedly, the color of container was the only element differently interpreted by the two nationalities. Practical applications: Most of the packaging elements were perceived similarly by the Dutch and Italian consumers, this suggests that there is no need to create different labels for products sold in different countries. The exception relies in the indication to use dark bottles for products sold in Italy and transparent for products sold in The Netherlands. Pungent features, even if tied with superior healthy properties, are preferred by a small share of consumers. Label and packaging can be used to better communicate the healthiness of the products, so indicating the origin and the organic production can be useful for companies, regardless of the country in which they operate. A positive trend of preference toward olive oil in emerging consuming countries, as The Netherlands, is expected, as the use of this product is spreading within the population as healthy concerns about diet is becoming increasingly important.
Insetti per l’alimentazione umana: barriere e drivers per l’accettazione da parte dei consumatori
Materia, V.C. ; Cavallo, Carla - \ 2015
Rivista di Economia Agraria 70 (2015)2. - ISSN 0035-6190 - p. 139 - 161.
As the overall demand for food increases, there is an urgent need of sustainable proteins. To what extent European consumers are willing to accept innovative ingredients in their diet is the main research question we address. Interviews are conducted on a sample of 45 Italian consumers and results are analysed through the laddering method with the aim to understand how consumers express their personal values. The paper intends to contribute to the ongoing debate on global food security addressing potential drivers of, and barriers to, Western consumer acceptance of insects-based ingredients in the food supply chain. Results show that a combination of socio-cultural barriers and fear is assumed to contribute to the lower acceptability of insects-as-food in Western societies.
