Abstract

Purpose

The purpose of this paper is to propose an initial step for understanding the sensory perception and purchase intent of Brazilian olive oil consumers. It also investigates the sensory perception and purchase intent for a Brazilian-made olive oil.

Design/methodology/approach

The sample, consisting of 115 surveyed consumers, is described demographically. The aspects related to sensory analysis and purchase intent associated with the key attributes indicated by the consumers are then discussed. Finally, consumer segmentation is carried out to characterize the consumers in more detail, in terms of both demographic and predictive variables for olive oil consumption.

Findings

Consumers displayed a sensory perception that is coherent with olive oil characteristics, thus being able to distinguish three different olive oils from a compound oil sample. Regarding purchase intent and preference, consumers showed mixed behaviors, which was not entirely convergent with the identified sensory aspects. Therefore, it was possible to segment them into three distinct groups: utilitarian, naïve, and expert consumers.

Originality/value

Brazil is an emergent olive oil market, which can create both research and business opportunities for the country. This preliminary study contributes to the advancement of this research subject in the non-traditional markets for olive oil.

Abstract

Purpose

Focused on the olive oil sector in Chile which is a non-traditional market (both in production and consumption), the purpose of this paper is to determine the implicit value of the most relevant attributes of olive oil on the final price charged by supermarkets to consumers through the hedonic pricing methodology.

Design/methodology/approach

Field work was carried out between September and October 2012 in 12 supermarkets belonging to the four most important Chilean retail chains. A log-linear price-attribute function was used to estimate the hedonic price function. The sample included 248 observations olive oil prices available to consumers in the leading supermarkets in the city of Chillán (Chile).

Findings

The model estimation results led to the observation that the attributes that most positively influenced final price are oil acidity level, tin can container of imported oil, and origin. On the other hand, the attributes that most negatively influenced final consumer price are retailer house brand and plastic container.

Research limitations/implications

A limitation of this study is associated with the geographic area where it was carried out, that is, the city of Chillán in the Bío-Bío Region, which is the second largest region and accounts for 12 per cent of the total population. Further research should include other cities such as Santiago (capital), Concepción, Curicó and Valparaíso.

Originality/value

This study can be considered as a first approximation of a hedonic pricing model estimation for olive oil in non-traditional markets like Chile, which is considered an emerging market.

Abstract

Purpose

This paper aims to evaluate hematological parameters, blood glutathione (GSH), serum glucose-6-phosphate dehydrogenase (G6-PD) and liver function in favism animals' models after oral intake with a mixture of pickled olives and Vicia faba (V. faba) seeds.

Design/methodology/approach

Favism is a life-threatening hemolytic crisis. It results from the ingestion of V. faba by the individuals. The hemoglobin (Hb), hematocrit (Hct), red blood cells (RBCs), white blood cells (WBCs), serum glucose, blood GSH, serum G6-PD, serum thiobarbaturic acid reactive substances (TBARS), liver protein and liver function were evaluated after oral administration with a mixture of pickled olives with V. faba seeds in favism animals' models.

Findings

The favism-, vicine- and convicine-treated animals showed a significant decrease (p < 0.01) in Hb (6.42, 7.23 and 5.96 g/dl), Hct (25.4, 26.4 and 25.1%), RBCs (2.56, 2.45 and 2.60 106 cells/mm3, WBCs (4.35, 4.25 and 4.30 103 cells/mm3), serum glucose (95.8, 97.1 and 96.5 mg/dl), blood GSH (24.7, 26.6 and 23.8 mg/dl), serum G6-PD (15.8, 15.9 and 15.7 U/L), serum aspartate aminotransferase (6.35, 6.59 and 5.97 U/L), alanine aminotransferase (4.49, 4.61 and 4.50 U/L), total protein (6.54, 6.59 and 6.40 g/dl), albumin (3.84, 3.91 and 3.75 g/dl), globulin (2.70, 2.48 and 2.65 g/dl) and liver protein (3.37, 3.10 and 3.42 g/g tissue) but a significant increase (p < 0.01) in serum TBARS (38.7, 38.9 and 39.4 nmol/dl), alkaline phosphatase (275, 271 and 281 U/L) and total bilirubin (0.93, 0.89 and 0.91 mg/dl) compared to Hb (16.3 g/dl), Hct (45.3%), RBCs (5.80 106 cells/mm3), WBCs (9.45 103 cells/mm3), serum glucose (96.5 mg/dl), blood GSH (39.7 mg/dl), serum G6-PD (36.1 U/L), serum TBARS (18.0 nmol/dl), serum aspartate aminotransferase (19.8 U/L), alanine aminotransferase (9.23 U/L), alkaline phosphatase (214 U/L), total bilirubin (0.57 mg/dl), total protein (8.76 g/dl), albumin (4.85 g/dl), globulin (3.91 g/dl) and liver protein (6.28 g/g tissue) in control group. The oral administration with pickled olives + V. faba, pickled olives + vicine and pickled olives + convicine into favism animals' models, vicine-treated animals and convicine-treated animals, respectively pushed all the above-mentioned parameters to near the control levels.

Originality/value

V. faba contains vicine and convicine glycosides. Vicine and convicine glycosides in V. faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The ß-glucosidase in pickled olives converts both vicine and convicine glycosides into aglycones divicine and isouramil, respectively, in aerobic condition outside the human body (in inactive forms) and prevent these glycosides to cause favism.

Abstract

Purpose

Experimental tourism can be understood as a new trend in tourist demand. Tourists want to experiment with lifestyles in different places. The information society shows how and where the best products are cultivated and is linked to how the quality of life should be. Nowadays, we are intended to know more and better things, both tangible and intangible, and new technologies show them to us immediately. One intends to live these opportunities as soon as they can.

Design/methodology/approach

From the experimental point of view Olive Oil Tourism (Oleotourism) emerges from the olive oil consumer’s interest in learning about the production process, so they can discover a lifestyle associated to this product. This research begins with an exploration of tourists’ motivations. Then, focusing on these consumers, this work has different targets: first, to assess how consumers perceive intangible aspects of olive oil and, second, to forecast the potential demand for oleotourism.

Findings

The development of tourism is the result of tourist entrepreneurs that react to the pre-existing demand/opportunity by identifying it in the tourist market.

Research limitations/implications

The consumer’s experience is important, but touristic trends are changing. The importance of olive oil may grow in the future because the nutrition benefits are known by all countries. The natural experience around olive oil will drive it to other stakeholders.

Practical implications

It is very early to recognize if the olive oil tourism industry is economically interesting, and whether innovative offers can be created based in olive oil and the lifestyle in rural areas.

Social implications

The local development around olive oil tourism could be a potential complement with the principal activities, which are usually agricultural activities, farmer interests and local and historical heritage. This is a means to foresee the plausible impacts of the development of oleotourism on tourist destinations, for which oleotourism might become a competitive advantage based on an agri-food product with many intangible profits: olive oil.

Originality/value

This is the first opportunity to learn about the personal interest of the consumer regarding olive oil. They give us the opportunity to know if the institutional offer about new destinations based on olive oil tourism will have a chance or will it be an economic complement with the principal activities.

Abstract

Purpose

This paper aims to evaluate effects of the fortification of polyphenolic compound mixtures of quercetin, caffeic acid, tryrosol and hydroxytyrosol in olive oil oxidation.

Design/methodology/approach

The authors measured olive oxidation initiated by copper using thiobarbituric acid reactive substance, as an indicator of lipid peroxidation.

Findings

Overall, most mixture combinations exhibited oxidation similar to olive oil alone. Some mixture combinations of polyphenolic compounds acted as antioxidants; however, as the concentrations were changed, they became prooxidant in nature.

Research limitations/implications

In vitro studies have limitations for extrapolation to in vivo and clinical studies.

Practical implications

Such information will be useful in determining optimal concentrations and combinations of antioxidants for reducing rancidity and perhaps as models that could be used to modulate various chronic diseases that are associated with oxidative stress.

Originality/value

Olive oil, along with fruits, vegetables and fish, are important constituents of health promoting diets, such as the Mediterranean diet. Active ingredients include monounsaturated fatty acids, oleic acid and a variety of antioxidants including various polyphenolic compounds.

Abstract

This research analyses the main structural factors of the organic olive oil sector in Sicily, and the effects of the European sustainable development policy (EEC Regulation 2092/91, EEC Regulation 2078/92). It examines the trade marketing of organic producers of olive oil like the initiatives to exploit European branding, typicalness, and European recognition of PDO (protected denomination of origin).

Abstract

Purpose

This study aims to produce a new type of healthy functional kefir by adding olive (Olea europaea) leaf extract and to determine its potential effect on the quality (physicochemical, sensory, phenolic contents and antioxidant properties) of kefir samples during storage at 4°C for 21 days.

Design/methodology/approach

For this purpose, four kefir samples were produced by using olive leaf extract in different amounts (A: 0% (control), B: 0.1%, C: 0.15% and D: 0.35%). The physicochemical, sensory, phenolic contents and antioxidant properties of kefir samples were investigated during Days 1, 7, 14 and 21 of storage. The study was conducted to optimize the olive leaf extract addition level to obtain better-quality kefir functional food.

Findings

From the results, it was determined that the addition of olive leaf extract affected the entire chemical components of the kefir samples (p < 0.05). It was found that the pH value decreased during storage. By contrast, it was observed that titration acidity values increased. The kefir sample with 0.35% olive leaf extract (D) had the highest total phenolic and antioxidant activity content (1,292.75 mg GAE/L and 10.20 mM TE, respectively) among the samples (p < 0.05). In the sensory analyses, the kefir sample with the highest score – in terms of sensory attributes – was the kefir sample containing 0.15% olive leaf extract (C).

Originality/value

Thus, it was concluded that kefir with added olive leaf extract could serve as a functional kefir of benefit to human health. When we looked at the enrichment studies on kefir as a functional product, no study has been found on the use of olive (Olea europaea) leaf extract, especially with kefir. In this sense, it is thought that the study will contribute to published literature.

Abstract

Consumers’ increasing need for safe and quality food has motivated this market research study. A customer satisfaction approach is followed to examine whether the quality of organic olive oil, the most important biological product that has recently entered the Greek food market, could affect consumers’ purchasing behavior. For this purpose a survey was conducted in the region of Thessaloniki, Greece. The implemented methodology is called MUlticriteria Satisfaction Analysis (MUSA) and takes into account that customers’ global satisfaction for organic olive oil depends on five criteria. The analysis showed that the average global satisfaction index was almost 78 percent. Health was considered to be the competitive advantage of organic olive oil. On the contrary, promotion and disposition seemed to be its greatest weaknesses. The price, along with the package, was also found to be significant. Finally, gives some recommendations for the continuing improvement of information and advertising, label information and image of the package, which are the weak characteristics of organic olive oil.

Abstract

Purpose

The purpose of this paper is to evaluate the market potential of food obtained from olive by-products. The marketing of such by-products (e.g. olive leaves and pulp) is a challenging opportunity for the sustainable development of the sector. Yet, consumer demand is still poorly understood. The paper contributes to filling the knowledge gap with an empirical survey of a sample of Italian consumers.

Design/methodology/approach

The authors provide an assessment of consumers’ willingness to accept (WTA) food from olive by-products. The authors collected structured questionnaire from a sample of 289 Italian consumers. The authors asked to consumers their willingness to try a variety of food products containing olive by-products, as a proxy for their WTA the products. In order to investigate the drivers of the average WTA, the authors used the information in the questionnaire to build four constructs of interest: technophobia, neophobia, perception of benefits and awareness about sustainable consumption. The choice of the constructs and the variables was driven by the existing literature.

Findings

The paper shows how the WTA food with olive by-products is a general attitude of the consumer, rather than product-specific choice. The results suggest that consumers perceive the use of olive by-products as a new technology for preparing well-known food products. The authors did not find statistical evidence of the wariness of olive by-products as new food products. Technophobia is the most important factor hampering the marketing of olive by-products.

Originality/value

The paper is a first attempt of exploring the topic of WTA food with olive by-products.

Abstract

Purpose

The concept of food safety systems is increasing worldwide among farmers, manufactures, and processors and is also affecting consumer perspectives. This trend primarily impacts food businesses and table olive processing firms. The study seeks to explore the major economic obstacles to the adoption of food safety systems in table olive processing firms.

Design/methodology/approach

All 59 table olive businesses in the Aydın Province of Turkey were included in the survey. In an effort to remove extraneous items and demonstrate internal consistency, Cronbach's alpha was calculated for each variable. To better specify the economic obstacles to food safety system implementation, data were examined with exploratory factor analysis using principal component extraction and varimax rotation.

Findings

Major economic obstacles that most prominently emerged from analyses may explain several key indicators including difficulties in employing well‐trained personnel required for food safety systems, insufficient training facilities for employees intended to aid in the implementation of food safety systems, deficiency of infrastructure and other physical conditions, and deficient financial support from government and non‐government organizations.

Research limitations/implications

The study investigated only table olive processors. Future research should include analyses of consumer behaviors.

Practical implications

The Turkish government must ensure implementation of food safety systems to increase public knowledge and accelerate government funds for the establishment of such systems in the food business industry.

Originality/value

The study contributes to the positive perceptions of managers and their behaviors towards implementation of food safety systems in table olive processing firms. Since the paper is one of only a few dealing with this topic, it provides key clues for dissemination of food safety systems adoption at the firm level.
