Abstract
Purpose
The purpose of this paper is to document the level of risk in the Québec egg sector (conventional and specialty eggs) and analyze the optimal choices of Québec egg producers that must allocate limited resources to production of different types of eggs.
Design/methodology/approach
A quadratic programming approach applied to expected mean-variance models is used to analyze the impact of risk on decision to invest when the resources must be allocated to different type of production that have different risk levels. The model is calibrated using monthly data from 2009 to 2016.
Findings
Results indicated multiple uncertainty sources (technological, cost of production, price of eggs) that vary according to the types of eggs. Given risk aversion parameters, producer would favor production modes with the lowest producers’ price variance, which correspond to free-run eggs. Results also indicated that in response to a greater intensity of risk aversion, the course of action producers may choose is to increase the relative production of free-run eggs.
Research limitations/implications
The empirical limits of this research are found in the lack of quality data on producer prices and costs for specialty eggs. Future research could explore the relationship between the growing impact of egg for processing, which price is based on the US price, and its relationship with specialty eggs.
Practical implications
The findings of the study will be useful for policy makers and managers of eggs supply chain. This is important, given the recent announcement by Canadian’s large retailers and fast food companies to increase cage free eggs offering and, in some cases, eventually only selling these types of eggs.
Originality/value
This study adds to the understanding of the role of risk and uncertainty in the investment decision of egg producers and different mode of production, as well as in the development of the growing production of specialty eggs in Canada. It fills a gap in the literature regarding the impact of risk in Canadian egg production. This gap is likely explained by the perception of a lack of risk in this supply managed sector in Canada and its small size relative to other supply managed sector.

Abstract
Purpose
To draw the frontiers of the functional food universe, to identify concepts that should be included in a broadly accepted functional food definition and to propose a definition.
Design/methodology/approach
Based on a review of the literature and the Delphi technique with a group of North American and European experts.
Findings
Four concepts were identified: the nature of food, health benefits, functions and regular consumption. Two dimensions, physiological effects and functional intensity, were developed to define the frontiers of the functional food universe and a definition is suggested.
Practical implications
A large number of definitions as well as great variations within definitions make it difficult to provide industry partners with robust information on market trends and market potential, or to appropriately protect consumers through legislation. This paper should contribute to the debate surrounding the type of food that should be considered a functional food and surrounding the lack of a common definition for functional foods.
Originality/value
This paper is the first one, to our knowledge, that attempts to conceptually define the frontiers of the functional food universe and to provide a definition of functional food which is not sensitive to cultural differences, can accommodate temporal variations and rely on previous knowledge (definition) as well as experts' opinions.

Abstract
Purpose
The purpose of this paper is to compare knowledge about dietary fats in some dairy products and other foods across consumers from France, (French‐speaking) Canada and the USA. A relation is explored between the types of information, knowledge levels and obesity predominance.
Design/methodology/approach
A nine‐question nutritional test was developed and administered to three samples of consumers, respectively in Grenoble (France), Quebec, Canada and Ithaca, New York. In France, Canada and the USA the number of participants was respectively 100, 107 and 120. Participants were recruited randomly outside groceries stores and the test was administered directly through one‐on‐one interviews.
Findings
Results indicate a significant gap in knowledge between consumers from the three countries studied. The level and quality of knowledge seems to be correlated with the nature of the informational background: a wider availability of information such as nutrition facts and public health recommendations on fat consumption seems to have a positive effect on the general level of knowledge. However, “technical” knowledge seems to be inversely correlated to the level of obesity.
Research limitations/implications
This work is of an exploratory nature and the sample might not be representative of the countries' population. Further works that link food knowledge and food consumption patterns would be needed.
Practical implications
This study gives weight to the hypothesis that a “science” or nutrient approach to food might not result in appropriate food choices; consumers losing sight of the big picture. To confirm this hypothesis, further work would be needed.
Originality/value
This is, to the authors' knowledge, the first cross‐country study that attempts to link the type of knowledge on fat in food and predominance of obesity. This should encourage nutritionist to further investigate this link. It should also concern the dairy industry, given most often consumers' perception of dairy products' fat content is overestimated, especially for fluid milk in France.
