During the past few decades, production and marketing of functional foods has increased in many countries including Iran. Considering the fact that consumers’ preferences play an important role in the success of marketing a product to increase consumption, this study aims to fill the knowledge gap in this regard in Iran.

The theory of social marketing served as the framework of this study. Qualitative data were collected via eight semi-structured focus group discussions, between May and September 2014. Participants were 65 women (44 housewives and 21 employed women), aged 23-68 years, selected by purposeful sampling technique, considering maximum diversity. All focus group discussions were audio recorded and transcribed verbatim. Analysis of the qualitative content of the data was conducted using MAXQDA® software.

The findings showed that there were quite diverse preferences among studied women in regards to different aspects of a product and its social marketing strategies. The preferences toward functional dairy products were categorized in four main groups: characteristics of products including sensory and non-sensory characteristics; price; place of the product supply; and promotion strategies of products categorized in three subgroups of informing and educating, advertising and recommending.

This study is the first study in this regard in Iran. Given the novelty of functional dairy products in the market, the diversity of preferences should be considered both in production of dairy foods and their promotion plans. This understanding can contribute to success of interventions to increase consumption of these products among consumers.

The purpose of this paper is to present an overview of different aspects of inulin functionality in meat and poultry products.

Several studies on the physiochemical, textural and sensorial effects of inulin incorporated in meat and poultry products as fat replacer and texture modifier were reviewed.

Inulin is a plant-derived carbohydrate composed of fructose units and glucosyl moieties at the end of the chain that exhibits unique nutritional and technological benefits. Among its main healthy characteristics, it has been reported to reduce the risk of colon cancer, arteriosclerosis, osteoporosis, diabetes and obesity, to maintain low levels of triglycerides and cholesterol in serum and stimulate the immune system. As a functional food ingredient, it can be used in various foods as a fat replacer, improves water-holding capacity and emulsion stability, as well as modifying the texture and viscosity of foods. Incorporation of inulin into meat and poultry products can be beneficial in producing low-fat products with desirable texture and sensory attributes.

There are limited reviews regarding the application of inulin in meat and poultry products. In this review, chemical composition and physicochemical properties of inulin, its health effects and various effects of inulin incorporation into meat and poultry products including, physicochemical, textural and sensory characteristics of these products are discussed.

Functional dairy products market has been growing steadily in Iran. Awareness and perception related to these products has an important role in consumers’ acceptance and subsequently long-term marketplace success of these products. The purpose of this paper is to fill the knowledge gap in this regard, study conducted in Iran.

The theory of social marketing served as the framework of the study. Qualitative data were collected via eight semi-structured focus group discussions (FGDs), between May and September 2014. Participants were 65 women (44 housewives and 21 employed women), aged 23-68 years, selected by purposive sampling, with a maximum diversity. All FGDs were audio recorded and transcribed verbatim. Qualitative content analysis of the data was conducted by MAXQDA®.

Almost all participants were unfamiliar with the term “functional dairy products,” although, some of them had consumed these products. Apart from perceiving the functional dairy products as unnecessary by some participants, some women did not trust in health claims of these products for various reasons such as distrust in food manufacturers, exposure to contradictory information, and fear of unforeseen and dangerous side effects due to taking them. The participants agreed on the need for more information from a trusted and credible source such as health professionals or authorities through different communication channels like television, training classes, shopping center, and so on.

This study provides a unique insight into consumers’ awareness and perceptions concerning functional dairy products in Iran. To the best of the knowledge, this study is the first study in this regard in Iran. Given the novelty of these products in the market, the findings could provide information for the dairy industry to expand its market and improve its profitability and reliability, as well as public health sector to design and implement intervention programs to promote functional dairy products consumption in the population.

Domestic refrigerators could be considered as one of the major potential sources of food-borne diseases, in addition limited data are available regarding the level of contamination of domestic refrigerators in Iran. The purpose of this paper is to detect some of bacterial contamination in domestic refrigerators.

In total, 104 households were randomly selected from ten health centers in five areas of Tehran, Iran. Visual inspection and temperature evaluation of the households’ refrigerators were done. In addition, the refrigerators were swabbed and analyzed for contaminants using polymerase chain reaction (PCR) method. DNA was isolated and purified by the proposed standard protocol.

Screening of the domestic refrigerators by PCR method showed that 51.7 percent of the samples were positive for pathogens as follows: L. monocytogenes 41.6 percent, S. aureus 5.5 percent, Salmonella spp 4.6 percent, and E. coli O157:H7 0 percent; consequently, none of mentioned pathogens were detected in 48.3 percent of the refrigerators. Results of the visual inspection indicated that 57 percent of the refrigerators were on desirable, 36.5 percent were acceptable, and 7 percent were weak conditions. Most of the refrigerators about 44 percent had desirable temperatures. There were no significant correlations between the visual inspection scores, temperature and frequency of isolation of specific pathogens in the domestic refrigerators. A significant correlation was observed between contamination and education of parents (p < 0.05).

Determination of the bacterial contamination and evaluating the temperature of domestic refrigerators in Iran can be considered as a novel approach of current study. These findings could be employed in designing and implementing appropriate educational interventions to promote food safety and diminish the risk of food-borne illnesses. Also, obtained results might be applied as introduction for further investigations.

The purpose of this article is to analyze the state-of-the art in a systematic way, identifying the main research groups and their related topics. The types of studies found are fundamental for understanding the application of artificial neural networks (ANNs) in cemented soils and the potential for using the technique, as well as the feasibility of extrapolation to new geotechnical or civil and environmental engineering segments.

This work is characterized as being bibliometric and systematic research of an exploratory perspective of state-of-the-art. It also persuades the qualitative and quantitative data analysis of cemented soil improvement, biocemented or microbially induced calcite precipitation (MICP) soil improvement by prediction/modeling by ANN. This study sought to compile and study the state of the art of the topic which possibilities to have a critical view about the theme. To do so, two main databases were analyzed: Scopus and Web of Science. Systematic review techniques, as well as bibliometric indicators, were implemented.

This paper connected the network between the achievements of the researches and illustrated the main application of ANNs in soil improvement prediction, specifically on cemented-based soils and biocemented soils (e.g. MICP technique). Also, as a bibliometric and systematic review, this work could achieve the key points in the absence of researches involving soil-ANN, and it provided the understanding of the lack of exploratory studies to be approached in the near future.

Because of the research topic the article suggested other applications of ANNs in geotechnical engineering, such as other tests not related to geomechanical resistance such as unconfined compression test test and triaxial test.

This article systematically and critically presents some interesting points in the direction of future research, such as the non-approach to the use of ANNs in biocementation processes, such as MICP.

Regarding the social environment, the paper brings approaches on methods that somehow mitigate the computational use, or elements necessary for geotechnical improvement of the soil, thereby optimizing the same consequently.

Neural networks have been studied for a long time in engineering, but the current computational power has increased the implementation for several engineering applications. Besides that, soil cementation is a widespread technique and its prediction modes often require high computational strength, such parameters can be mitigated with the use of ANNs, because artificial intelligence seeks learning from the implementation of the data set, reducing computational cost and increasing accuracy.
