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.info:eu-repo/semantics/publishedVersio

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

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

Effect of VacuumImpregnation and High Hydrostatic Pressure Treatments on Shelf Life, Physicochemical, and Sensory Properties of Seabream Fillets

Marination is commonly used to preserve fish, which, in combination with other non-thermal technologies, such as vacuum impregnation and high hydrostatic pressure, may help to preserve freshness and extend shelf life. In addition, marination may mask changes in physicochemical properties and the sensory attributes of fish resulting from intense pressurization treatments. In this study, we evaluated the effects of vacuum impregnation (50 mbar for 5 min) alone or in combination with a moderate pressurization treatment (250 MPa for 6 min) on the physicochemical properties, microbiological and oxidative stability, and sensory properties of refrigerated seabream fillets. Compared to conventional marination, vacuum impregnation alone had no effect on the aforementioned properties, except for a higher perception of lemon aroma (0.9 vs. 1.6). However, vacuum impregnation with pressurization reduced the total viable mesophilic aerobic bacteria to counts below 4 log colony forming units (CFU)/g after 16 days of storage at ≤ 2 °C, compared to 6 log CFU/g with conventional marination. Additionally, the color and texture were affected by the pressurization treatment. However, color was more susceptible, and at the beginning of storage, lightness was higher in the pressurized samples than in the control (52 vs. 78). Regardless, this whitening effect and other minor changes in texture and sensory properties compared to conventional marination with vacuum impregnation with pressurization can be considered of little relevance considering the increase in shelf life, the lack of lipid oxidation (maintained at low and similar levels as those of the non-pressurized samples), and the intrinsic whitening effects of certain marinades.info:eu-repo/semantics/publishedVersio

Farmed or wild fish? Segmenting European consumers based on their beliefs

Wild fish cannot meet the global demand of fish, making aquaculture the most suitable alternative to support increase in fish consumption. However, farmed fish have a less positive image among consumers than their respective wild-caught equivalents. Food product images can be affected by consumers' beliefs, which are useful to infer the quality of the food product and the consumers' food choices. This paper investigates European consumers' beliefs regarding farmed versus wild fish. The goal is to understand not only what hinders farmed fish consumption but also provide guidelines for producers and governments to improve the image of farmed fish. An online questionnaire reaching 2511 consumers in five European Union (EU) countries (France, Germany, Italy, Spain, and the United Kingdom) assessed 19 beliefs. The results showed that European consumers believed that wild fish had a higher quality, but that farmed fish were superior in terms of control, price, and availability. Even though most consumers were in favour of wild fish, they reported higher consumption of farmed fish, suggesting that positive perceptions of products do not necessarily drive higher consumption. European consumers also believed that farmed fish were less fresh and contained higher concentrations of antibiotics than wild fish. These inferential beliefs that view aquaculture negatively should be addressed in future marketing campaigns to transform them into informational beliefs. Promotional and marketing campaigns should reinforce the positive attributes of farmed fish, including their lower levels of chemical hazards (e.g. heavy metals and marine pollutants) and biological hazards (e.g. parasites). Based on the assessed beliefs, consumers were categorised into five clusters of individuals: pro-wild fish, slightly pro-wild fish, balanced view, open to aquaculture, and pro-aquaculture. The identification of these consumer segments and their profiles should help producers and marketers focus their efforts to enhance the image of the aquaculture.info:eu-repo/semantics/acceptedVersio
