Setting up of a sensory panel for the analysis of water (SUSPAW).

Legislation on the quality of water intended for human consumption requires routine taste and odour controls. So far, no procedures or technical documents exist which can be used as a reference in the training of sensory assessors for tap water. This work presents the procedure for the development of a trained panel and it describes all the steps carried out: the recruitment, pre-selection, selection and training phase considering the different odours and flavours that tap water may contain.

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.

Suckling or non-suckling? Sensory characterization of commercialized lamb meat according to feeding.

Consumption of meat from suckling lambs is typical in some regions. However, sensory differences between meat from suckling and non-suckling lambs are barely described in previous studies. The objectives of the present study were (a) to develop a method to describe the sensory characteristics of lamb meat, including the development of sensory references for odor, flavor, and texture attributes; and (b) to study the sensory differences between lamb meat commercialized as "suckling lamb" and that commercialized without this designation.

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.

Short communication: To what extent do environmental or technological conditions affect the sensory differentiation of raw ewe milk cheeses produced in valley or mountain farms?

This work discusses the extent to which differences in technological or environmental conditions affect the sensory properties of cheeses made in mountain or valley farms. The work is focused on Idiazabal cheese, frequently made with lamb rennet paste and with milk from sheep flocks managed under extensive grazing systems. Fourteen sensory attributes were assessed, and free fatty acid content and rennet lipase activity were analyzed in cheeses from mountain and valley farms.

Effects of seasonal changes in feeding management under part-time grazing on terpene concentrations of ewes' milk.

Terpene composition of ewes' raw milk from nine commercial flocks was analysed from February to July. Ewes' diet consisted of concentrate and conserved forage in winter (indoor feeding) and part-time grazing from spring (transition and outdoor feeding). Regardless of the feeding, limonene and β-phellandrene were the most abundant monoterpenes and β-caryophyllene showed the highest concentrations among sesquiterpenes.
