Abstract

Purpose

The purpose of this study is to investigate the effect of lemon juice on the survival of Salmonella Enteritidis and Escherichia coli in cig kofte (raw meatball).

Design/methodology/approach

Cig kofte samples were inoculated one by one with both bacteria at high inoculum levels and were treated with different doses of fresh lemon juice (2, 5, 10 and 15 ml) for 10 seconds, 30 seconds, and 1, 5, 15, 30 and 60 minutes.

Findings

Treatments of lemon juice for different exposure times caused reduction ranging between 0.1 and 1.7 log CFU/g for Salmonella Enteritidis and 0.1 and 2.1 log CFU/g for E.coli. Results showed that lemon juice caused slight decrease in Salmonella Enteritidis and E.coli as an immediate inhibitor, but this effect increased with concentration and time.

Originality/value

This is a research study to provide information on the effectiveness of lemon juice which is squeezed generally before eating cig kofte, on the presence of the surface flora to strengthen the hygienic quality of the product. Inactivation effect of lemon juice on Salmonella Enteritidis and E.coli may give a practical and easy way of providing food safety for cig kofte.

Abstract

Purpose

Nowadays, natural products are preferred for food safety and preservation due to the demand of consumers. The industrial methods which have been in use for a long period of time have had an adverse impact on organoleptic properties of foods or on human health. The purpose of this paper is to investigate the antibacterial effects of unripe grape products on natural and inoculated micro-flora of lettuce as an alternative functional and natural antibacterial agent for consumers and food industry.

Design/methodology/approach

The antibacterial effects of products on initial micro-flora of lettuce were detected. The lettuce samples were treated with products for different treatment times (0, 5 and 10 min). The antibacterial effects of products against inoculated micro-flora on lettuce were obtained. Lettuce samples were separately inoculated with food-borne pathogens (~4 log CFU/g) and treated with products for the same treatment periods.

Findings

Unripe grape products decreased the initial micro-flora by approximately 1 log CFU/g in 5 min. Unripe grape products dramatically inhibited the inoculated E. coli on lettuce samples right after the treatment. Majority of the unripe grape products decreased the number of S. Typhimurium and L. monocytogenes to an undetectable level in 5 min. S. aureus was the most resistant microorganism among the tested cultures. It was concluded based on the conspicuous results on the inhibition of E. coli, S. Typhimurium and L. monocytogenes that unripe grape products can be considered as natural antimicrobial agents for food safety.

Originality/value

This study is also valuable since it enables the in situ testing of the potential usage of unripe grape products against food-borne pathogens.

Abstract

Purpose

Although religiosity and advertising messages have been extensively examined in the existing literature separately, studies which correlatively examine both these aspects are very limited. This paper aims to reveal the influence of the widely used religious messages on consumer attitudes and of purchase intentions on subjects with different levels of religiosity.

Design/methodology/approach

In this study, four different printed advertising messages with and without religious messages were developed for two different products. In this respect, the consumer attitudes toward advertisements and the degree to which purchase intention changed were measured.

Findings

The attitude and purchase intention toward the advertisements with religious messages was found to have a higher mean value compared to the advertisements without religious messages, and a statistically significant difference was found between the two. The highly religious participants’ attitudes and purchasing intention toward the advertisements with religious messages differed as compared to the participants with low levels of religiosity.

Research limitations/implications

Indeed, it was observed that the attitude toward different advertising messages and purchase intention differed regarding the level of religiosity. In the last section of the study, the influence of the level of religiosity on purchasing intention and consumer attitudes has been discussed with academic and practical results.

Practical implications

This study has also extended the practical implications of social judgment theory, which suggests that the further the consumers’ initial position to the new message the less is the acceptance of that message, and it contributes to its methodological and theoretical development. Whether a religious advertisement message is considered more or less acceptable depends on the level of religiosity and the positioning strategy adopted in the advertisement. In the present study, it is observed that as the level of religiosity increases, purchase intention and the attitude towards the advertisement with religious message increase in permissible(halal) goods. However, when prohibited (haram) services are considered, an increase in the subjects' level of religiosity brings about a decrease in the purchase intention and the attitude towards the advertisement with religious message. Therefore, this study validates social judgment theory.

Social implications

A significant implication for the marketing practitioners is that religiosity could be one of the criteria in segmenting market. A religiously prohibited product might gradually feel more irritating as the intensity of religious message increases in an advertisement. Thus, it is an important consideration for an organization offering faith-based products in mono-religious societies. Clearly, marketers need to be very careful when they use religious symbols in the secular marketplace, which raises the question – What factors underlie a positive response to religious message use in advertisement?

Originality/value

Religion was a taboo subject in society in the recent past; it has not been comprehensively investigated in marketing literature; moreover, it is evident that this situation continues to exist at present. It can, therefore, be said that the efforts to conceptualize religion’s influence on marketing and consumer behavior have been scarce.

Abstract

Purpose

The aim of the study is to determine the effect of street food experience on behavioural intention and to determine the relationship between the street food experiences and behavioural intention.

Design/methodology/approach

In this research, a quantitative research method and a structured questionnaire form are used. The author has used a 48-item questionnaire. The questionnaire contains three categories. In the first section of the questionnaire form, there were 14 questions to determine gender, education, age, income state and demographic findings of the participants. In other sections, a Likert scale with 5 points (strongly agree–strongly disagree) was used.

Findings

It was found that street food experience affects behavioural intention and also there is a significant positive relationship between street food and behavioural intention. The research includes constructive propositions for many institutions and organisations such as local businesses and local governments. In spite of the shortcomings of basic research about the impact of the street food experience on behavioural intention of the tourist, there is still some need of other with a wider sample and different studies to understand the impacts of street food experience. In addition, future studies can focus on the relationship between street food experience and food culture.

Originality/value

In tourism literature, there are so many research studies that examine tourist experience. Many of these studies are about the relationships between food and cultural experience. Nevertheless, no study has been conducted on similar relationships between street food and behavioural intentions in the literature. There are also some other studies that discuss different types of tourism experience. However, there has not been found any research on tourist experience of street food. In prior studies, rather than street food impacts on experience, food impacts on tourist experience have been emphasised. In this way, this study is important in terms of contributing both qualitative and quantitative studies.

Abstract

Purpose

The purpose of this paper is to examine the efficacy of microbial elimination using different sanitizers in raw vegetables (cherry tomatoes, spring onions, Chinese chives, and chicory) and to analyze the efficacy of Escherichia coli O157:H7 reduction by type of sanitizer and vegetable.

Design/methodology/approach

To assess the sanitizing effects of microbial elimination by variety of vegetable, the samples were grouped into four different washing methods: control (no sanitizer), 100 ppm chlorine, 100 ppm electrolyzed water, and 200 ppm electrolyzed water after prewashing. Subsequently, quantitative microbiological experiments were conducted to assess aerobic mesophilic plate count (APC), coliform, E. coli, and Bacillus cereus, and sensory changes of the sanitized vegetables were tested. Thereafter, measurement of the sanitizing effects on bacterial reduction after inoculation with E. coli O157:H7 was conducted.

Findings

The microbial levels of four types of vegetables ranged from 3.37 to 5.24 log CFU/g for APC, 2.41 to 5.57 log CFU/g for E. coli, 0.25 to 5.40 log CFU/g for coliform, and 0.83 to 5.44 log CFU/g for B. cereus. After three types of sanitizing treatments, microbial reduction effects showed 0.94-1.84 log CFU/g for APC, 0.56-1.00 log CFU/g for E. coli, 0.18-1.26 log CFU/g for coliform, and 0.56-1.23 log CFU/g for B. cereus (p<0.05). In sensory evaluation, there were no significant differences in taste and flavor between with and without sanitizing treatments. Regarding bacterial reduction after inoculation with E. coli O157:H7, the microbial reduction on vegetables was shown to be in the range of 0.27-1.57 log CFU/g with 100 ppm sodium hypochlorite, 0.66-3.07 log CFU/g with 100 ppm electrolyzed water, and 0.79-2.55 log CFU/g with 200 ppm electrolyzed water. Chicory, cherry tomato, and spring onion showed significant reduction levels of E. coli O157:H7 after sanitation (p<0.05).

Originality/value

This study revealed that different sanitization methods are required for different types of vegetables. Electrolyzed water treatment (100 ppm) is a more effective and safe method of washing raw vegetables. Given that the main purpose of sanitizing fresh-cut produce is to maximally reduce microorganism levels, different methods of sanitizing fresh-cut produce with an adequate washing method should be used according to vegetable type.
