Abstract

:
Environmental consciousness, health consciousness, social consciousness—today, all three terms have become buzzwords that influence food consumer behavior and reach many consumers. A number of consumer trends have emerged, which manufacturers have responded to, giving consumers the opportunity to make purchasing decisions that reflect any or all of these three buzzwords. In the context of palm oil, all three of these buzzwords may be associated with a consumer-perceived problem. They may be aware of the social (e.g., child labor), environmental (e.g., burning of rainforests) or potential health impacts communicated by the media. Today, more and more products claim to be palm oil free. Related to this the main question of the research is “why do consumers choose palm oil-free foods?” The results of our model using the theory of planned behavior show that the factor most influencing purchase intention is consumer attitude towards palm oil. The only significant effect on this factor is the environmental impact. Neither the perceived health-, nor the social effect had a significant effect on shaping attitudes among the respondents. A further result of the model is that perceived behavioral control only directly affects actual behavior, but does not influence intention, indicating that although there is a possibility for respondents to purchase palm oil-free products, it was not necessarily a conscious, intentional purchase.

1. Introduction and Literature Review

What motivates a consumer to buy food that is in line with the trend of ethical consumption? Why is ethical consumption becoming an increasingly important trend? As to what is meant by ethical consumption, although it has been approximated by many researchers, there is no well-defined, uniformly accepted definition. It is generally understood as consumer choices and behaviors based on morals, and described as green consumption, sustainable consumption, responsible consumption, mindful or conscious consumption and critical consumption [1]. Looking at the growth of the market for some products that demonstrate ethical consumption (e.g., fair-trade, vegan, organic), there is a clear trend towards the rise in these types of products [2,3]. Although the growth of the market is evident from the statistics, the share of ethical products in the total market is small [4]. The consumer’s purchase of such products may be due to an underlying large consumer megatrend. In Törőcsik’s [5] research about the megatrends of food consumption, one of the priority areas is morality, which also covers ethical food consumer behavior to a large extent, as it includes environmental awareness, sustainability, fears and ethical considerations as well as responsibility. These elements also characterize ethical consumer behavior. According to Bezençon and Blili [6], products that have an environmental or social impact that can influence consumers’ decisions are considered “ethical”.
Environmental [7,8] and social impacts [9,10] associated with consumption can be considered as the two main strands of ethical consumption. As a result, there are a number of consumer trends and product developments in the market that follow the principles of ethical consumption, such as fair trade and organic products.
Boycotting different food ingredients—for example, because of social or environmental impacts—is a common manifestation of ethical food consumption. Palm oil is the most widely produced vegetable oil and the most widely consumed vegetable oil in food products [11]. There are many reasons why palm oil has become so prevalent in products, such as its versatility, productivity, price and availability, but there is also a countertrend. Several major NGOs (e.g., Greenpeace) have highlighted the harm that palm oil production can cause [12]. There are also health, social and environmental issues associated with palm oil as perceived by consumers. In recent years, palm oil has also received negative press coverage [13]. This may have led to some countries having the second highest growth rate in the free-from market for palm oil-free products [14].
This begs the question, why do consumers buy food that is free of something? The market for different free-from foods has been the subject of a number of research studies, including on risk perception, quality [15] and health impact [16]. The range of free-from products can be diverse: gluten (wheat)-free, lactose-free, sugar-free, or an area that has recently become the focus of increasing research, palm oil-free products. One of the reasons behind free-from foods is the health consciousness of the consumer, i.e., the belief that by eating free-from foods they can buy healthier food. However, it has also been shown specifically in the context of palm oil that one of the influencing factors for consumers to buy palm oil-free foods is the health impact [17]. Health impact is also an important element in the research, since as Oke et al. [18] have shown, selfish reasons, such as the consumer’s own health and well-being, can also underlie ethical food consumption behavior. Nevertheless, free-from products tend to be perceived by consumers as healthier than conventional products [16], so this is another factor that may motivate consumers in the direction of buying and consuming palm oil-free products.
Palm oil-free products are an emerging trend in the free-from food market, with a growing market share in European markets. This is confirmed by a statista.com report on Italy, where palm oil-free products are the third largest market share gainer [19].
This led to the objective of the paper, to understand why palm oil-free food is purchased. The basic elements of the theory of planned behavior were extended by the three main factors, consumer thoughts about health on the line of “free-from” products and consumer thoughts about the social situation and environmental issues on the line of ethical food consumption behavior. The theory of planned behavior is a model that is still widely used today and has been applied in a wide range of research to understand food consumption behavior [20,21,22,23,24]. The model, through its core elements, can provide a well-grounded answer to why consumers engage in the specific behaviors they do. Despite being a well-structured and widely used model in the consumer behavior research community, this model has not been used in previous research to understand the purchasing behavior of palm oil-free food products. In view of this, and the grounding of the model, a conceptual model for the current research was developed and is presented in the first figure.
In the present paper, the theory of planned behavior [25] is used, which assumes that the development of an explicit behavior is preceded by an intention, the development of which is influenced by three factors. These are perceived behavioral control, attitudes towards behavior and subjective norms. The model assumes that if these three factors have a positive and significant effect on the intention, it is highly likely that the intention will be formed in the consumer, which may further lead to the actual behavior. If, however, any of the above factors does not influence the intention, it can be assumed that this factor will also act as a barrier to the behavior.
Based on the above and the model presented in Figure 1, the following questions are sought to be answered in the research:
RQ1: Which factors contribute most to the intention to purchase palm oil-free food products?
RQ2: Which element of the theory of planned behavior does not influence the formation of conscious ethical consumer intention and thus the intention to purchase palm oil-free food products?
RQ3: Is the perception of environmental, social or health impacts more important in shaping attitudes towards palm oil?

2. Materials and Methods

2.1. Consumer Survey

To answer the research questions, primary research was conducted in July–August 2021. The questionnaires were completed online and 327 respondents were interviewed. In all cases, respondents gave their written consent for their answers to be analyzed. The questionnaire was completed anonymously and respondents had the option to stop completing the questionnaire at any time if they did not wish to continue.
In constructing the questionnaire, the elements of Ajzen’s [25] theory of planned behavior were the primary considerations and the statements they made were used in the research [26]. In addition, a number of other research studies have been used to formulate the claims for each category, such as Zemore and Ajzen [27] for the intention scales, Parveen and Ahmad [28] for the subjective norm and Shin and Hancer [29] for the subjective norm. In addition, the questionnaire specifically asked respondents about palm oil, palm oil-free products and consumer beliefs about the environmental, social and health impacts of palm oil. These statements were formulated based on research by Capecchi et al. [30]. Demographic and other characteristics of respondents were measured at the end of the questionnaire.
Table 1 shows the distribution of the sample by variables and other consumer characteristics.
The sample is non-representative, with a predominance of women under 35 in terms of age and in terms of education, those with tertiary education. There is also a group that stands out in terms of residence, with a higher proportion of respondents from the capital. Furthermore, as can be seen in Table 1, those with lower incomes and lower educational attainment are under-represented.

2.2. Data Analysis

In order to construct the proposed model, the data were analyzed using structural equation modelling (SEM). The analysis was performed using SmartPLS software [31]. The previously mentioned statements were applied in the model construction. The latent variables were constructed using elements of the theory of planned behavior, while attitudes towards social, health and environmental impacts associated with palm oil were decomposed using elements of the personal beliefs category created by Capecchi, Amato, Sodano and Verneau [30].
Since a reflective model has been built, a consistent PLS algorithm and consistent bootstrapping have been applied.
The statements used in the model which were based on the above mentioned references [25,26,27,28,29,30,32] are summarized in Table 2.

3. Results

3.1. Construct Reliability and Validity of the Model

The model was structured using the attitudinal statements already mentioned in the consumer survey and summarized in Table 2. The reliability of the model is supported by a number of indicators, including Cronbach’s alpha, composite reliability and average variance extracted (AVE) and the individual outer loadings, which are presented in this order.
Based on the intercorrelation between the claims used, the reliability is estimated using Cronbach’s alpha values [33], which are all above the threshold value of 0.7 prescribed by Cortina [34], with the lowest value being 0.759.
Composite reliability values, which are similar in content to Cronbach’s alpha [35], but still an important measure due to its limitations [33], should also exceed 0.7 [36]. The lowest value in this study was 0.757.
The average variance extracted (AVE) and outer loading values [33] are important indicators for examining the relationships between the statements that provide the main elements that build the model. Average variance extracted (AVE) values ranged from 0.514, also meeting the minimum value of 0.5 [37].
The lowest value among the outer loadings was 0.626. In principle, a value above 0.7 is acceptable for this indicator [38]. However, in social research, it is often the case that this value will be lower than 0.7 [39], as in two cases here. According to Hair et al. [33], in such a case, “… indicators with outer loadings between 0.40 and 0.70 should be considered for removal from the scale only when deleting the indicator leads to an increase in the composite reliability… above the suggested threshold value”. Accordingly, the model was tested without the two statements in question, but the composite reliability values showed no significant increase, so the two statements were retained in the model. Overall, based on the results presented so far, the reliability of the model can be considered good.
The different values are summarized in Table 3.

3.2. Model Fit, Discriminant Validity and Explanatory Power of the Model

In this section, the indicators of model fit, discriminant validity and explanatory power of the model are discussed.
The test of discriminant validity is important because it examines the differences between the elements that build the model, since if this criterion is met, it means that the elements that build the model are unique and are not explained by the other elements in the model [33]. Two indicators, the Fornell–Larcker test (Table 4) and the Heterotrait–monotrait (HTMT) criterion (Table 5) were used to measure this.
The Fornell–Larcker test is considered satisfied if a given latent element explains the variance of its own indicator better than the variance of the other latent elements [40], which, as can be seen from Table 4, is satisfied in this study.
The results of Table 5—HTMT criterion—also show that discriminant validity has been established, as the obtained values are all below 0.9 [41].
The explanatory power of the model is presented in terms of R2 and Adjusted R2 values, which are summarized in Table 6. The model explains 54.8% (Adjusted R2 = 0.548) of the formation of consumer behavior and 62.9% (Adjusted R2 = 0.626) of the formation of purchase intention for actual behavior. In addition to these R2 values, which can be considered high, it is also important to note the value for attitude, which took a relatively low value compared to the previous two.
To examine the fit of the model, SRMR (Standardized Root Mean Square Residual) and NFI (Normed Fit Index) are presented. According to Hulland [39], an SRMR of less than 0.8 and an NFI of greater than 0.95 indicate a good model fit. In this model, the SRMR was found to be 0.062, thus fulfilling the first criterion. However, the NFI values according to Marsh et al. [42] can vary depending on several factors, so the value of it was not used as a cutoff value. The results show that the overall model fit is good (SRMR = 0.062, NFI = 0.850). The low NFI value may be due to the relatively low sample size, which often leads to underestimation of the fit [43].

3.3. Results of the Model

Consistent bootstrapping was used to determine the significance level of each relationship and the T- and f2 values. The results are presented in Table 7 and in Figure 2 below.
In models built from the elements of the theory of planned behavior, it is important not only to know which characteristics have a significant effect, but also which do not. This is because the model assumes that if all three factors have a significant influence, i.e., if the people in the environment and family members are supportive, if the opportunities to form the intention and subsequently carry out the behavior are available, and if the consumer’s attitudes are appropriate, then the intention will be formed in the consumer and this can be further developed into concrete behavior. From this perspective, the model in Figure 2 suggests that the intention to purchase palm oil-free products is most influenced by the consumer’s attitudes (β = 0.690, p = 0.000), followed by the subjective norm (β = 0.184, p = 0.000), which is also significant but weaker, but the perceived behavioral control is absent and its effect is not significant.
In the context of perceived behavioral control, it was also examined whether it has a direct effect on purchasing behavior towards palm oil-free products, for which a significant effect was found. These suggest that although some palm oil-free product purchase does occur, it is not necessarily conscious, it is just that the consumer takes the product off the shelf and sees that it is palm oil free. Hence, there is an awareness that he or she has just bought palm oil-free products, but it is not the result of a deliberate search. Another explanation for the model’s results is that although there are environmentally conscious consumers, they do not implement environmentally conscious purchasing behavior for various reasons. This paradox is highlighted in the research by Hinsch et al. [44]
As an objective of the research, another aim was to determine whether and to what extent consumer beliefs about environmental, health and social impacts affect attitudes towards palm oil and, indirectly, intentions and actual behavior. The results show that the only one of the three factors that significantly influences attitudes is consumer thinking about environmental impacts (β = 0.392, p = 0.000).

4. Discussion

In addition to the basic elements of the theory of planned behavior, the present research investigated the social, environmental and health-related thoughts related to palm oil and their impact on the intention to consume palm oil-free products and on actual behavior. The results show that two factors directly contribute to the realization of behavior: an existing, already established intention and the extent to which consumers have the means to purchase such products. However, of the two factors, intention is the stronger influence on behavior. Several factors in the model already play a role in the formation of consumer intention. The consumer’s environmental concerns towards palm oil play an important role in shaping consumer intention, i.e., if a company aims to sell palm oil-free products, it must aim to change consumers’ attitudes and strengthen their feelings towards palm oil. The model also shows that attitudes are strongly influenced by consumers’ attitudes towards palm oil, so if a company’s long-term strategy is to focus on attitudes, it is worth designing its communications to highlight the environmental impacts of palm oil, as this is the factor that has the strongest impact on attitudes. This could be achieved, for example, by saying that the product is palm oil-free, but also by explaining the importance of this a little more, for example by using a picture of the environmental impact or another appropriate claim. This can also be achieved through the use of third-party certification labels [45] through electronic word-of-mouth [46] or with the tools of green marketing [47].
A number of limitations emerged in the current research, which could also serve as objectives of future studies. The first of these was sampling. The sample was not representative and was only collected in one country, and it would be worth expanding this in a future study. Nevertheless, in a future study, it would be worthwhile to test the model specifically among consumers who admit to being conscious consumers and pay attention to the effects investigated in the present study.
When describing the indicators of the model, R2 and Adjusted R2, it is noticeable that although intention and behavior scored high, this is not the case for attitude. It can be assumed that other factors may be more strongly involved in shaping attitudes than the elements presented in the present model, and it would therefore be worthwhile to extend the model with additional elements.
