“…Although 74% of the 410 answers were affirmative to give economical support to this additional guarantee, 26% disagreed because they thought virgin olive oil was quite expensive already. This aspect would require a specific study since the price sensitivity of consumers depends on many social and economic factors, which also have geographical differences and evolve over time [ 10 , 51 , 52 ].…”

A survey was launched to understand the current problems and sensitivities of the olive oil market through a series of questions clustered around topics related to quality, traceability, regulation, standard methods and other issues. The questions were selected after a series of interviews with different actors to identify those aspects where some disagreement or different points of view may exist. These questions were grouped in topics such as geographical traceability, consumer perception and quality management. The survey was addressed to eight different olive oil actors independently: producers, retailers, importers, exporters, analysts, workers at regulatory bodies, and consumers. Approximately half of the respondents (67.0% for consumers and 56.0% for the rest of olive oil actors) claimed to understand the importance of the protected designation of origin. In fact, the traceability objectives that were selected as the most relevant were those related with geographical traceability (19.3%) followed by the detection of adulteration (15.6%). Most of the respondents (80%) would agree to share data for a common database; however, some concerns exist about the use of these data and the issue of paying to have access to this database. The respondents mostly expressed an affirmative answer concerning the efficiency of panel test (74%) and a negative answer (90%) concerning the proposal of removing from regulation, although 42% agree with their revision for improvement. The opinions on “best before” date and their relationship with quality and the willingness to apply non-targeted methods were also surveyed.

“…A study conducted by Marakis et al in Greece revealed that a significant portion of participating households (60.3%) utilized olive oil produced by themselves, their extended family, or friends, while only 27.4% purchased branded olive oil. Moreover, approximately 57% reported using EVOO [ 49 ].…”

Nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disorder, is closely associated with insulin resistance, obesity, and metabolic syndromes. A body of research has proposed that olive oil, a basic component of the Mediterranean diet with antioxidant and anti-inflammatory properties, may alleviate metabolic disturbances and retard the progression of NAFLD. We conducted a systematic review and meta-analysis to assess the effectiveness of olive oil intake in people with NAFLD. We systematically searched the major electronic databases (PubMed/MEDLINE, Scopus, Cochrane Central Register of Controlled Trials), as well as grey literature sources, to identify randomized controlled trials (RCTs) investigating the effects of olive oil consumption on biochemical and anthropometric parameters of individuals with NAFLD. The quality of the studies was evaluated using the risk-of-bias tool 2.0 (RoB 2). The mean difference (MD) and the 95% confidence interval (CI) were calculated using fixed-effects and random-effects models. Seven RCTs involving 515 subjects were included in the analysis. In the random-effects model, no statistically significant differences were identified with respect to alanine transaminase (MD = −1.83 IU/L, 95% CI: −5.85, 2.19 IU/L, p = 0.37, I2 = 69%) and aspartate transaminase (MD = −1.65 IU/L, 95% CI: −4.48, 1.17 IU/L, p = 0.25, I2 = 72%) levels or waist circumference values (MD = −0.23 cm, 95% CI: −1.23, 0.76 cm, p = 0.65, I2 = 0%). However, a significant effect on body mass index was observed (MD = −0.57 kg/m2, 95% CI: −1.08, −0.06 kg/m2, p = 0.03, I2 = 51%) for subjects who received olive oil compared to those who received an alternative diet or placebo. The findings of the present meta-analysis suggest a modestly positive impact of olive oil intake on body weight in people with NAFLD.

“…Virgin olive oil is also used in the management of catering and product supply processes which is not necessarily linked to its territorial origin and is easily available on the market at more accessible consumer prices than EVO oils or those with a protected designation of origin [23]. As a result, the market for EVOO that has been certified by brands of origin and organic production is dominated by household use [24,25] which has grown during the epidemic because of the restrictions that were put in place to stop the spread of the disease.…”

The present study examines the elements that influence Italians' willingness to pay a higher price for organic olive oil. As a result, a survey was conducted involving a heterogeneous sample of 332 consumers and their propensity to spend a surplus price was examined using a logit model. According to the study findings, consumers are willing to pay more for organic olive oil and this willingness to pay increases with age, education level, living in a smaller household, consumption of organic food and traditional sources such as producers, retailers and supermarkets. The empirical investigation demonstrates the convenience for farms of converting olive oil production from conventional to organic in order to fulfill customer needs. Companies are able to plan their medium-and long-term commercial activities when they can predict customer preferences. Indeed, consumer information may have a beneficial effect on the community as a whole due to the considerable quantity of positive environmental externalities associated with organic olive production.
