A plethora of research in recent years has been devoted to estimating consumer demand for genetically modified food, an important piece of information needed to create appropriate public policy. To examine this body of work, a meta-analysis was conducted of 25 studies that, in aggregate, report 57 valuations for GM food. Findings indicate as much as 89% of the variation in existing value estimates for genetically modified food can be explained by an econometric model that controls for (a) the characteristics of the sample of consumers studied, (b) the method for eliciting consumers' valuation, and (c) characteristics of the food being valued. Each of these factors has a statistically significant effect on estimated premiums for non-GM food. Results of... |

AbstractWith the aim of comparing the acceptance of milk obtained from cloned, genetically modified (GM) and conventionally bred cows among working adults and university students, and identifying and characterizing typologies among both subsamples in terms of their preferences, a survey was applied to 400 people in southern Chile, distributed using a simple allocation among the subsamples. Using a conjoint analysis, it was found that consumers preferred milk from a conventional cow. Using a cluster analysis, in both subsamples two segments sensitive to production technology were identified. Rejection of cloning was greatest among university students, whereas a higher proportion of working adults rejected GM. The segments differed in terms of area of... |

This study evaluates consumer acceptance of different GM applications in the pork production chain. In general, results indicate that consumers prefer conventional pork over pork for which genetic modification was applied. However, the negative impact of the GM applications is compensated by improvements in quality, increased animal welfare, a lower impact on the environment, less residues and a price discount. Of these benefits, increased animal welfare has the most positive effect on consumer choices. With substantial monetary compensation and presence of various benefits the consumers will attach higher utility to the GM pork than to the conventional pork. The amount of monetary compensation is dependent on the type of GM application. |

Abstract Quinoa is an Andean crop with extraordinary nutritional properties. Its high protein content and well-balanced amino acid composition make it a unique food product for health-conscious consumers. The aim of this study was to develop a cereal bar using organic quinoa with amaranth, chia seeds, nuts and dried fruits. Seven bar prototypes were designed and evaluated in a consumer acceptance test where the attributes flavor, sweetness, texture, and appearance were assessed. The prototype with the highest acceptance scores had the following composition: 9.1% puffed quinoa; 12.1% quinoa flake; 6.1% puffed amaranth; 5.2% chia seeds; 12.1% dried cranberry; 15.2% macadamia nut; 12.1% sunflower oil; 18.2% honey; 9.1% panela; 0.8% agar-agar. The selected... |

Several studies proposed changes in winemaking technology in order to improve wine quality, reflecting on its high acceptance. Thus, the aim of this work was to evaluate the influence of pre-drying and constant pumping effect technologies on sensory attributes of Bordô (Ives) and Isabel red wines through the acceptance evaluation of appearance, aroma, body, flavor and overall acceptance. Eighty consumers evaluated the samples using a 9-point structured scale and sensory data were analyzed by Cluster Analysis followed by Multidimensional Scaling. Significant differences (P<0.001) were observed in the comparison of the samples in all sensory attributes, highlighting the wide acceptance of the samples from innovative winemaking. In addition, Cluster... |

Abstract: This study evaluated the influence of O2-absorbing sachets into different packages polyethylene terephthalate (PET ? E1), low density polyethylene (LDPE ? E2), and PET/LDPE (E3) on the quality of minimally processed soybean sprouts (MP-sprouts). The MP-sprouts were stored up to 12 days and characterized for physicochemical, microbiological and sensory attributes. The O2-absorbing sachet showed changes during exposure to the environment by the formation of amorphous iron hydroxide, which was observed by the analysis of functional groups and XRD. The packaging used in the study showed high transmittance and clarity, and low Haze, being a good feature for storing the MP product. All packaging systems showed an increase in the volume of absorbed... |

Tofu was elaborated using water-soluble extract of soybean grains from the cultivar BRS 267 with cardoon flower (C. Cardunculus L.), as coagulant as an alternative to the traditional coagulant magnesium chloride. The tofu were evaluated in relation to physical, chemical, microbiological and sensory properties during 14 days. Was obsersed for the tofu coagulated with cardoon flower that the moisture, pH, total mineral, protein, and syneresis decreased with the storage, while Kunitz Trypsin Inhibitor, ureatic activity and phytic acid did not change. It was also obtained a positive effect for color (L*, a*) parameters, phytic acid, yield, syneresis, and acceptance. The textural properties, showed a tendency to increase of hardness and stickiness, while... |

The influence of risk perception and risk attitudes in the process of accepting genetically modified (GM) food is often ignored, and particularly whether both constructs (latent variables) have a combined effect in explaining consumer acceptance. Similarly, the inclusion of organic product standards juxtaposed to GM food is unknown. This paper attempts to shed some light on this question by examining the decision making process through the use of structural equation modeling (SEM). We use survey data from Spain and a set of theoretical constructs that allow us to identify independent mechanisms underlying individuals’ risk decision making. Our results suggest that the conceptualized model captures the decision making process, and that both perceptions and... |
