Effect of a health claim on consumer acceptance of milk-based dessert containing omega-3

This study was to evaluate the influence of information on the addition of omega-3 and its health benefits in the acceptance of dairy dessert. The hedonic thresholds methodology was applied in two trials: blind and open-label. In the blind trial, no information was provided to consumers regarding the formulation of the flans. In the open-label trial, consumers received the information on the addition of omega-3 and its health benefits. The value of compromised acceptance threshold (CAT) was not influenced by the information on the addition of omega-3 and its health benefits. However, there was a high increase in the value of hedonic rejection threshold (HRT) when the consumers were informed of the benefits of omega-3, and it was possible to increase the addition of the compound in the flans by up to 21.03% without causing product rejection, confirming the positive effect of information on health benefits in accptance.

Positive Effect

Designed-enriched products have been recently one of the most interesting areas of research and innovation in the animal production and food industry. These products are considered functional foods and contain ingredients that have beneficial physiological effects on human health. Designed or enriched eggs are an important type of functional food in poultry production. Demand for functional foods in the market has been increasing in recent years. Due to the increased interest of people in buying designed products, there is a production adjustment in the poultry industry. Composition change of laying hens feed affects nutritional composition change of eggs as well as their quality preservation. This process can an effect of the change in the concentration of cholesterol and its fractions, fatty acids, and pigments in eggs. It is evident from the relevant scientific literature that designer eggs consumption can have a positive effect on human health. Therefore, the aim of this paper is to describe different concepts of designer eggs production and emphasize the health benefits of their consumption in humans.

Purpose The purpose of this paper is to analyse the appropriateness of the analytical hierarchy process (AHP) to measure consumers’ acceptance and preference for eggs enriched with omega-3 (n-3) fatty acids as a health claim and to compare its results with the traditional nine-point hedonic scale. Design/methodology/approach The AHP was used as a multi-criteria decision analysis. Data were obtained from a face-to-face questionnaire completed by 122 consumers in a controlled environment in Cataluña (Spain). Findings Results showed the capacity of the AHP to analyse consumers’ acceptance and preferences. An agreement between the AHP and the nine-point scale was found showing that n-3 enriched eggs had lower flavour acceptance, conventional eggs had higher yolk colour acceptance, and conventional and the free-range eggs had similar and higher odour acceptance than the other egg types. The most important attributes that determine preferences for egg purchase were the type and the egg price followed by the origin and the egg size. Research limitations/implications The AHP approach seems to be a reliable tool to evaluate consumers’ hedonic preferences. However, further testing on other food products with larger sample size is needed. Originality/value The AHP methodology has been widely used in many fields in the last decades, but to the knowledge, not in the sensory field. In the Spanish market, studies that analyse consumers’ preferences and acceptance of eggs are scarce, and new insights are needed particularly regarding n-3 enriched eggs.

Active Substances

Nutraceuticals are defined as foods or their extracts that have a demonstrably positive effect on human health. According to the decision of the European Food Safety Authority, this positive effect, the so-called health claim, must be clearly demonstrated best by performed tests. Nutraceuticals include dietary supplements and functional foods. These special foods thus affect human health and can positively affect the immune system and strengthen it even in these turbulent times, when the human population is exposed to the COVID-19 pandemic. Many of these special foods are supplemented with nanoparticles of active substances or processed into nanoformulations. The benefits of nanoparticles in this case include enhanced bioavailability, controlled release, and increased stability. Lipid-based delivery systems and the encapsulation of nutraceuticals are mainly used for the enrichment of food products with these health-promoting compounds. This contribution summarizes the current state of the research and development of effective nanonutraceuticals influencing the body’s immune responses, such as vitamins (C, D, E, B12, folic acid), minerals (Zn, Fe, Se), antioxidants (carotenoids, coenzyme Q10, polyphenols, curcumin), omega-3 fatty acids, and probiotics.
