In recent decades, organic farming based on natural means and methods of production is gaining more and more popularity. It is due to the growing awareness of the society regarding the harmfulness of chemicals used in intensive agriculture, which influences the growing interest of both producers and consumers in organic food. Searching for plant cultivars performing best under organic management in terms of crop quality is one of the important research topics of the recent years. The aim of the present study was therefore to compare 8 oat and 17 barley cultivars grown in identical organic production conditions in terms of polyphenols and carotenoids contents and the mycotoxins contamination in grains. The analyses of bioactive compounds were performed using HPLC and the mycotoxins occurrence using LC-MS/MS methods. Among the barley cultivars studied, the grains of SU Lolek, Rubaszek and Podarek accumulated the highest content of polyphenols. Grain of Soldo cultivar was richest in carotenoids, but at the same time most of the mycotoxins identified within the study were found in the grains of this cultivar. In the case of oat, the highest content of polyphenols was found in the grain of Harnaś, Nawigator and Arden cultivars, while Pascal and Amant grain was richest in carotenoids. Among all the oat cultivars tested, only Amant grain was free from the studied mycotoxins. These findings are important for producers as well as consumers, who search for quality organic foods.

AbstractIn Australia, the retail value of organic food production was estimated at A$250 million, with farm-gate value at around A$90 million and exports at around A$40 million, in 2002. The current share of organic sales in total food sales in Australia is about 1%. The growth rate in organic production was forecast to continue at 10–30% per annum. Despite the positive outlook, there are consumer concerns about product recognition and product integrity. To understand how demand for organic products is changing, it is important to investigate consumer attitudes and knowledge about these issues. The objective of this study was to identify issues that may hinder or promote demand. Given the qualitative nature of these issues, we used a focus group study to probe consumers. While focus group results are a qualitative approach and not intended to be generalizable, the results suggest directions for future research. The participants raised concerns about the use of chemicals, the treatment of farm animals and the environmental impact of food production. Organic food consumers were found to be more knowledgeable about organic foods, as well as being more tolerant of higher prices and inaccessibility. The results also suggest that increasing consumers' awareness of organic farming and certification, as well as the availability of organic foods, may be the most effective way of moving organic foods into mainstream.

In the last twenty years the organic movement has faced a great interest. Europe has the largest organic market; however the demand for organic foods is concentrated in Western Europe. The Central and Eastern European countries, like Romania, are becoming important cereal suppliers for the Western Europe. Despite the increasing of the home organic production, the Romanian consumer does not buy and eat organic food products. This paper investigates the barriers of the organic food choice. A study was delivered in Cluj Napoca city among the adult population. The aim of the study was describing the consumers' buying behaviour in an organic food purchasing context. The questionnaire was structured into five sections: general food purchasing habits, the consumer' knowledge regarding the organic foods, organic foods buying habits, reasons of the nonconsumption and identification questions. The accent is put on the evaluation of the consumers' knowledge on this category of products. The main conclusion is despite the consumers consider them-selves consuming organic food, they do not are able even to identify or characterize them.

The demand of organic food is increasing despite its premium pricing and lack of availability particularly in developing countries like Bangladesh. This paper aims to provide the insights about organic foods and the intention consumers have to purchase or not to purchase organic food. The pesticide-residue problem has opened a market opportunity for organic food as it is produced without any form of synthetic chemicals. As there was insufficient literature, a survey was conducted on 900 respondents on six major supermarkets selling organic food in the capital city of Bangladesh. It is found that, consumers expect the organic foods to be healthier, tastier, and environment friendly. The organic food buyers tend to be older with child, have higher education level and family income than those of non-buyers. The barrier of organic food is that majority consumers have less knowledge and do not know the main differentiation between organic foods and traditional foods.

Many retailers have expanded and diversified their private label food product assortment by offering premium-quality private label food products such as organic products. With price being identified as the major barrier for organic food purchases, private label organic food products could be a suitable and more affordable alternative for many consumers. While numerous studies have examined consumer preferences for organic food, very few organic food studies have incorporated the concept of private labels. This study addresses this research gap by studying consumer preferences and willingness to pay for national brand and private label organic food using a latent class model. Specifically, this study analyzes consumer preferences for organic eggs and orange juice and the effect of national branding versus private label. Findings show heterogeneity in consumer preferences for production method and brand, with three consumer segments being identified based on their preferences for both juice and eggs. For eggs, about half of the consumers prefer private label and organic production, whereas one-quarter clearly prefers organic, and another quarter is indifferent about the brand and the organic production. For orange juice, the majority (75%) prefer the national brand. In addition, one-quarter of the consumers prefers organic juice, and about one-third values both organic and the national brand.

As barley and oat production have recently increased in Canada, it has become prudent to investigate these cereal crops as potential feedstocks for alcoholic fermentation. Ethanol and other coproduct yields can vary substantially among fermented feedstocks, which currently consist primarily of wheat and corn. In this study, the liquified mash of milled grains from 28 barley (hulled and hull-less) and 12 oat cultivars were fermented with Saccharomyces cerevisiae to determine concentrations of fermentation products (ethanol, isopropanol, acetic acid, lactic acid, succinic acid, α-glycerylphosphorylcholine (α-GPC), and glycerol). On average, the fermentation of barley produced significantly higher amounts of ethanol, isopropanol, acetic acid, succinic acid, α-GPC, and glycerol than that of oats. The best performing barley cultivars were able to produce up to 78.48 g/L (CDC Clear) ethanol and 1.81 g/L α-GPC (CDC Cowboy). Furthermore, the presence of milled hulls did not impact ethanol yield amongst barley cultivars. Due to its superior ethanol yield compared to oats, barley is a suitable feedstock for ethanol production. In addition, the accumulation of α-GPC could add considerable value to the fermentation of these cereal crops.

Background: Sales of organic foods are increasing due to public demand, while genetically modified (GM) and irradiated foods are often viewed with suspicion. Aim: The aim of this research was to examine consumer attitudes toward organic, GM and irradiated foods to direct educational efforts regarding their consumption Methods: A telephone survey of 1838 residents in Tennessee, USA was conducted regarding organic, GM, and irradiated foods. Results: Approximately half of respondents (50.4%) purchased organic food during the previous 6 months (‘consumers’). The most common beliefs about organic foods by consumers were higher cost (92%), and fewer pesticides (89%). Consumers were more likely than non-consumers to believe organic food tasted better (prevalence ratio 3.6; 95% confidence interval 3.02–4.23). A minority of respondents were familiar with GM foods (33%) and irradiated foods (22%). Conclusion: Organic food consumption is common in Tennessee, but knowledge about GM and irradiated foods is less common. Consumer health education should emphasize the benefits of these food options, and the safety of GM and irradiated foods.

PurposeThis research aims to assess the consumers' intention to purchase organic foods for balanced physical and mental growth. It examines the decision-making process in buying organic products built on the extended Theory of Planned Behaviour (TPB). This study designed a model to show how Bangladeshi consumers wish to purchase organic food.Design/methodology/approachData were collected by means of a formal questionnaire from shoppers in different markets who buy organic and non-organic foods. Statistical analysis is done by applying partial least square-structural equation modelling (PLS-SEM).FindingsFindings refer that among the four antecedents called social norms (SN), personal attitude (ATT), perceived behaviour control (PBC) and health consciousness (HC), three (ATT, PBC and HC) have a significant influence on the intention to consume organic food in Bangladesh. The only cognitive variable called social norm (SN) has no statistically significant impact though it positively relates to the behavioural intention to purchase organic food.Research limitations/implicationsThe fitted model did not consider any moderating or mediating variable though there might be such effects regarding organic food purchase and consumption. The study includes a major portion of the respondents from less than Tk. 20,000 monthly income group, which is a price-sensitive group from Bangladesh perspective. Hence, this price sensitivity might have a slight influence on the results of the study.Practical implicationsThis study includes four variables as the predictors to describe consumers' intention to purchase organic food products in Bangladesh. Among the predictors, health consciousness or awareness is found to be most powerful. Though consciousness is the key, the awareness of Bangladeshi citizen regarding organic food is lower than in other parts of the world. Hence, the research model directs the policymakers to increase awareness through different social campaigns.Social implicationsUnder Vision 2040 of promoting sustainable development, the government of Bangladesh is trying to increase organic food consumption. Production and consumption of organic food will positively impact society since organic fertilizers are environmentally friendly and do not harm society. This research promotes a strategy formulation to ensure the consumption of organic foods for a positive social impact.Originality/valueThis study is a unique research to concentrate on the importance and factors influencing the consumption of organic foods in Bangladesh, a recently graduated developing country. Furthermore, it extended the Theory of Planned Behaviour (TPB) and proposed a new conceptual framework.

Organic agriculture is a promising and increasingly demanded direction of “greening” agricultural activity, which has a great potential due to natural production technologies. Significant segments of organic products have been formed in the food markets of the developed countries; various institutional systems of the industry have been functioning for decades. Russian agribusiness is globally lagging behind in these matters, but the development of the economic environment has led to the objective necessity of adopting a law and a state standard that would define the requirements for the organic agriculture. Research on the prospects of the Russian food market in the global organic production system is becoming relevant. This work is a two-sided quantitative and qualitative approach to the study of existing production systems of organic food from the standpoint of the results and dynamics, on the one hand, and their organizational and economic structure, on the other. The findings and results are confirmed by the presented and systematized absolute and relative indicators of land areas certified for organic agriculture, the number of market entities, the consumption of organic food per capita and retail sales in the domestic markets. The qualitative characteristic of organic agriculture systems was reflected in constructing a set of schemes that clearly illustrate national features of the conduct methods, state regulation of production and turnover, research support, regulatory and supervisory support of the business under study. As a result, a comparative analysis of the leading world markets for organic food (USA, Germany, Canada and Austria) in comparison with the emerging market of Russia. The study is addressed to the global business community operating in the organic food market and to special research institutions.
