Sensory evaluation of Protected Designation of origin Wines: Development of olfactive descriptive profile and references

Wines covered by PDO or PGI quality labels have specific sensory characteristics. According to EU regulations, product characteristics (including the sensory description) must be defined in the PDO technical specification and should be verified for their compliance. There exist internationally harmonized quantitative descriptive sensory methods applied to products such as virgin olive oil, with well-defined attributes described in the method itself. Currently, in the case of wine, there is no harmonized international sensory descriptive method that allows comparison of results between different PDOs or laboratories. In this work, a qualitative and quantitative olfactory profile for a broad variety of wines (11 PDO and 37 wine types) and their corresponding reference standards are proposed. The sensory profile obtained can be used both to verify compliance with the technical specifications of the product and to categorize wines by type or region, thus becoming a powerful tool for the wine sector.This work was supported by Catalan Institute of Vine and Wine (INCAVI).

Development of a Descriptive Profile and References for the Assessment of Taste and Mouthfeel Descriptors of Protected Designation of Origin Wines

Producers of PDO (Protected Designation of Origin) wines must submit to the EU authorities’ technical specifications that include the specific sensory description of each product typology, to be subsequently checked by the competent authority in each country. Unfortunately, there is no consensual and standardized approach for the development of sensory control methods for PDO wines. The aim of this work was to develop a sensory profile for the taste and mouthfeel descriptors that allows the characterization of wines from 11 existing PDOs in Catalonia (Spain), and with the purpose of advancing the process of harmonization of the official sensory analysis of wines. This paper includes the selection process of tasters, the procedure used for the definition and grouping of descriptors, and the development of references for the selected attributes. The use of this analytical tool should allow PDO/PGI product certification and control authorities to verify compliance with their specifications (descriptive and quantitative) based on objectively evaluated results.This research was funded by the project MINORVIN “Valorization of minority grape varieties for their capacity to diversify viticulture and oenology and to minimize the effects of climate change in wine quality,” RTI2018-101085-R-C33 (MICINN/AEI/ERDF, EU)

Consumers’ Expectations about Meat from Surgical Castrated or Immunocastrated Male and Female Iberian Pigs

A common practice in Iberian pigs is the castration of both males and females, and it can be carried out surgically or by immunization against gonadotropin-releasing factor (GnRF). The aim of this work was to determine consumers’ overall liking and expectations towards Iberian pork from five different sex types (castrated females, entire females, GnRF-vaccinated females, castrated males and GnRF-vaccinated males), as well as to know the attitudes and beliefs of consumers towards castration and immunocastration. Loins from 83 Iberian pigs were collected and evaluated by 252 consumers in Barcelona and Madrid. Consumers evaluated the five types of meat in three situations: blind condition (tasting the product), expectations (without tasting) and informed condition. Finally, attitudes and beliefs towards castration and immunocastration were also determined. Results distinguished three segments of consumers labeled as “Indifferent”, “Against castration and immunocastration” and “Against immunocastration”. Meat from castrated males had higher overall liking scores in the blind condition. Expectations towards pork depending on its sex type affect consumer-informed acceptability; thus, it is important to consider marketing strategies to avoid or direct the effect of the information provided on the acceptability of the pork.info:eu-repo/semantics/publishedVersio

Consumer attitudes toward consumption of meat products containing offal and offal extracts

The development of food products containing offal and offal extracts could be part of the solution to the upcoming demand for animal protein. This study aimed to determine Spanish consumers’ attitudes toward offal and the development of meat products containing offal extracts. Consumers’ perceptions were evaluated by means of focus group discussions and a survey (N = 400) to validate the focus group results in various Spanish provinces. The theory of planned behavior was used to examine consumer attitudes. Results indicated that nutritional properties, environmental sustainability, and affordability were the main drivers, while sensory attributes, low frequency consumption, and perceived higher content of undesirable compounds were the main barriers. Three segments were identified according to their beliefs: those in favor of these products, those that were health and environmentally conscious, and those who were reluctant about them. The identification of these segments and their profiles demonstrated the necessity to focus efforts on providing reliable information on sensory and health-related issues to improve acceptability. Attitude was the most important predictor of behavioral intention regarding the global model, while the social component (subjective norm) was significant for two of the identified segments, emphasizing the relevance of the social component for acceptability.info:eu-repo/semantics/publishedVersio

A cross-cultural perspective on impact of health and nutrition claims, country-of-origin and eco-label on consumer choice of new aquaculture products

Over the last decade, an increasing number of new value-added aquaculture products made their way onto the European market, as a response to growing demand for healthier diet, and more sustainable and locally produced protein sources. The importance of these drivers of consumer choice for aquaculture products' acceptance paves the way for a relevant reorientation of the European aquaculture industry towards a more consumer-centred approach. This research uses discrete choice experiments to examine the effect of health and nutrition claims, country-of-origin (COO), and eco-labels on consumer choice of new aquaculture products in a cross-cultural context. Three products with different preserving methods have been chosen for the study: fresh (chilled), canned, and smoked product. Results indicate that COO label “produced in own country” together with ASC eco-label function better than the health and nutrition claims as driver of choice. Results further point to the existence of different segments of “nutrition conscious”, “ethnocentric”, “price conscious”, and “eco-conscious” consumers.info:eu-repo/semantics/acceptedVersio

Consumer Acceptance and Preference for Camel Milk in Selected European and Mediterranean Countries

In this paper, we analyse consumer acceptance, preferences and attitudes to camel milk based on a cross-country study based on qualitative focus groups with consumers. Outside the main consumption countries where camel milk is a regular part of the daily diet, many consumers buy this product primarily due to its promised health benefits. Furthermore, they are willing to pay a substantial price premium for camel milk. The findings from the literature study suggest the need for further research aimed at improving the sensory quality of camel milk, camel milk fermented products (such as yoghurt, kefir, etc.) and camel milk cheese. In addition, the application of flavours could be an option to cover the perceived salty taste of camel milk. Another aspect is that more research needs to be conducted to optimize the operating parameters and standardization of the production procedures of camel milk yoghurt in the future. In general, we can state that so far only a few consumer studies exist and, in particular, for European consumers, not much is known about their attitudes, preferences and acceptance to try or to buy such a product.info:eu-repo/semantics/publishedVersio

"One Fish, Two Fish, Red Fish, Blue Fish”: How ethical beliefs influence consumer perceptions of “blue” aquaculture products?

Respecting ethical beliefs of consumers is an important precondition for food manufacturers in their attempt to improve their positioning in the European food market. Based on a cross-cultural survey of 2511 European participants, this research demonstrates how ethical beliefs affect consumer perceptions of “blue” (i.e. environmentally friendly) aquaculture products. The study further emphasises that the positive effect of ethical beliefs on purchase intention operates via an indirect route mediated by consumers’ trust in a product category. Consumer involvement has limited moderation effect on the above relationships. To expand its “blue” business, a key policy recommendation to aquaculture product manufacturers and policy makers is to urge stable and reliable standards of control in environmentally responsible aquaculture production so that consumers can rely on the information source and increase their trust in aquaculture products.info:eu-repo/semantics/acceptedVersio
