Abstract
Purpose
The aim of this study was to produce an enriched honey powder with active compounds coming from bee pollen and investigate the effects of bee pollen addition as a carrier material on honey powder.
Design/methodology/approach
The effects of bee pollen addition as carrier material in corporation with gum arabic at different ratios (25, 50 and 75% of total carrier material amount) on vacuum-dried honey-bee pollen powder were investigated.
Findings
The bee pollen concentration raise in the mixture increased the particle size, total phenolic, flavonoid and sugar contents and antioxidant activity, whereas decreased the Hauser ratio and Carr index values, hygroscopicity and solubility of enriched honey powder samples. The honey powder samples had passable and poor flow properties and very hygroscopic (>20%) structure because of the high sugar content. The phenolic and flavonoid contents of honey powder samples with bee pollen changed between 1531.59 and 3796.00 mg GAE/kg and 424.05–1203.10 mg QE/kg, respectively, and these values were much higher than the control sample. On the basis of linear correlation analysis, there was a very high positive correlation between total phenolic, flavonoid and antioxidant activity, while there was a very high negative correlation between these parameters and solubility.
Originality/value
The study evaluated that enriching of honey powders with pollen, which is a product of both plant and bee origin, rather than enriching with different plant and animal sources has an innovative approach. Additionally, the usage of bee pollen as a carrier agent in food drying has not been previously reported in any study.

Abstract
Purpose
This study aimed to evaluate the compositional changes and bioaccessibility of phenolics and antioxidants in propolis during in vitro digestion as well as the cytotoxic effects of digested propolis on various cancer cell lines.
Design/methodology/approach
Six propolis samples were obtained and subjected to in vitro oral, gastric and intestinal digestion. Both digested and undigested samples were analyzed for their total phenolic, flavonoid and antioxidant activities. Additionally, changes in phenolic composition in the in vitro digestion system were revealed by the HPLC-DAD system. The cytotoxic effects of the digested samples were assessed on lung (A549, H1299), skin (A431), liver (Hep-G2) and colon (Caco-2) cancer cells as well as on fibroblast (Bj) cells.
Findings
The mean bioaccessibility values of phenolic and flavonoid compounds were found to be less than 35 and 24%, respectively, while the TEAC and CUPRAC antioxidant results ranged between 225.08–649.04 and 398.68–1552.28 µmol TE/g, respectively. The release of p-coumaric, ferulic, 3,4-dimethoxycinnamic acids, naringenin, pinocembrin and chrysin increased progressively from the oral to the intestinal stage. The cytotoxic effects of samples on cell lines were ranked, based on IC50 results, as A431 > Hep-G2 > Caco-2 > A549 > H1299 > Bj.
Originality/value
Propolis has been recognized for centuries as a natural remedy, and numerous studies have explored its bioactive components. However, no studies have previously examined the changes in the phenolic compositions of propolis samples during digestion or their cytotoxic effects on cancer cells. Therefore, this study provides novel insights and an approach to the existing literature on this topic.

Abstract
Purpose
Financial literacy is crucial in explaining a broader set of investment behaviors. This paper investigates what financial literacy, wine knowledge, risk propensity and wine purchase behavior have in common.
Design/methodology/approach
The analysis is on a questionnaire distributed online to an equal number of young adults from a traditional wine-producing and consuming country (France) and a country less linked to wine by tradition (the UK).
Findings
The analysis shows how financial literacy, financial education and financial risk attitudes impact the attitudes toward wine purchase decisions. Results indicate that participants prefer to drink wine for pleasure rather than for potential financial gain. Significant relationships exist between financial literacy, wine consumption frequency and willingness to store and pay for wine.
Originality/value
These results allow for a better understanding of wine purchasing behavior in light of willingness to pay, invest and store.
Highlights
- (1)
Financial literacy has a positive role in influencing wine storage and investments.
- (2)
Culture shapes the impact of financial literacy, habits and risk on wine investments.
- (3)
Gender and age have a role in influencing wine investments.

The purpose of this study is to test Islamic religiosity scale’s reliability and validity and to evaluate the impact of Islamic religiosity on materialism in Turkey.
Abstract
Purpose
The purpose of this study is to test Islamic religiosity scale’s reliability and validity and to evaluate the impact of Islamic religiosity on materialism in Turkey.
Design/methodology/approach
Using a quantitative research method, a self-administered survey was distributed to the students of two faculties – Faculty of Theology and Faculty of Business – of the same university in Izmir, Turkey. In total, 400 questionnaires for each faculty were distributed and a total of 529 completed questionnaires – 326 from the Faculty of Theology and 203 from the Faculty of Business – were returned. Exploratory and confirmatory factor analyses were conducted via SPSS and AMOS.
Findings
Islamic religiosity and materialism have been found to be negatively correlated, supporting the existing literature. However, not all the dimensions of Islamic religiosity (behavioral religiosity, spiritual religiosity and necessity of religion) had this negative effect on materialism (possession-defined success, acquisition centrality and acquisition as the pursuit of happiness). Negative influence of “behavioral religiosity” on all three dimensions of materialism was observed. However, the “spirituality” dimension of religiosity was found to have a positive impact, while the “necessity of religion” had no significant impact on the dimensions of materialism.
Research limitations/implications
A sample consisting of undergraduate students might limit the generalizability of the findings to Turkish Islamic population in general. This study is one of the first attempts to test the Islamic religiosity scale which needs to be further analyzed and developed.
Originality/value
The present study will contribute to the literature by testing an Islamic religiosity scale developed by a Turkish researcher. Besides, this is the only study undertaken on the impact of Islamic religiosity on materialism using an Islamic religiosity scale.
