This work investigated a model for the reuse of Citrus × clementina Hort. by-products for the development of a functional drink able to exert antioxidant, hypoglycaemic, and hypolipidemic effects. Juice obtained from fruits collected in three different areas of Calabria (Italy) was analysed. C. × clementina juice from Corigliano Calabro (JF), characterized by the highest content of bioactive compounds and bioactivity, was chosen as a matrix to be enrichment with hydroalcoholic ultrasound-assisted maceration of C. × clementina leaf from Corigliano Calabro (CO2) and ethanol ultrasound-assisted maceration of C. × clementina peel from Cetraro (BC3) extracts at different concentrations. The highest phytochemical content and bioactivities were found in juice enriched with leaf and leaf + peel extracts, with particular reference to antioxidant activity. In order to estimate the effects of pasteurization, 20% (mg/100 mL) enriched juice was subjected to this process. Based on obtained data of bioactivity and sensorial analysis, C. × clementina by-products could be proposed as a promising source of bioactive compounds useful for the formulation of a functional drink for preventing diseases associated with oxidative stress such as type 2 diabetes and obesity.
The product can be defined as a “basket of attributes” which provides the customer with the functional value specific to that class of product, as well as a set of secondary values (called benefits or services) which may be necessary or added. These additional services differentiate the brands and may have determining influence on customer’s preferences. Within the “GLASOIL” project (ID CUP J77H18000280006) the research activity focused on the development of the new product (olive oil based dressing) as a whole through the evaluation of the basket of attributes. Once the main reference targets had been defined, the survey focused on the expectations and evaluations of potential customers with respect to the new product. Investigating consumer preferences, before a product is launched on the market, is fundamental for companies and makes it possible to reduce failure rates. Through the creation of a focus group, the preferences and opinions of potential consumers on a new olive oil-based condiment were investigated. From the results obtained, different combinations of packaging were elaborated, subsequently used as graphic stimuli to carry out tests with eye tracking, aimed at verifying the presence of possible weak points of the packaging before launching the product on the market. The results show that, for this specific type of product, consumers preferred a transparent package that makes the product visible inside, characterized by elegant lines and equipped with a drop breaking cap. On the label, on the other hand, consumers, in addition to the information required by law, wanted to see the origin of production and instructions on possible use. In conclusion, the analysis with eye tracking showed that images with elements such as a hand using the product, prove to be “winning”, as they attract the observer’s attention. Eye tracking analysis also confirmed that men and women look at the packaging and label differently.
The role of wine and food products in tourism is multiform and complex. Throughout human history, food has not just been a means of subsistence, but has often become an element for authentic experience, socialising and hospitality. Within the context of global tourism, enogastronomy determines the qualitative level of the offer. It can be said that nowadays the package of goods destined for tourism is enriched by a new attribute, that of quality food, which has taken on a social aspect: more and more tourists travel to specific destinations because of good food. Traceability and protection brands are, without doubt, indicators for measuring the quality of food. The propensity to purchase and consume "traced" food were analysed with specific reference to olive oil. Data were collected through a 500Hz binocular remote eye-tracking system and analysed with SPSS software.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
