The aim of this study was to evaluate the effect of ultrasound (US) treatment on the postharvest of “Isabella” grapes and the consistency of the obtained results regarding the composition of anthocyanins in grape juice over three successive harvest years using a combination of analytical techniques.

Juices produced from “Isabella” grapes sonicated for different durations (3, 5, 7 and 10 min) were analysed. The grapes were harvested and sonicated in 2013, 2014 and 2015, and each treated sample was stored for 1, 3 and 5 days in order to verify the time necessary for the development of the US response. The juices were analysed through physicochemical analysis (total monomeric anthocyanins). The anthocyanin profiles were quantified and identified using high performance liquid chromatography coupled to photodiode array and mass spectrometry detectors (HPLC-PDA-MSn).

The results demonstrated the potential of US in improving the quality of grape juice. In all three harvests, it was observed that the treatments were effective in increasing the concentration of anthocyanins. For the 2013 harvest, the application of US for 5 min led to a 103% increase in juice pigments. However, the US response profile varied among the three harvests, indicating that the US effect was influenced by the ripening conditions of the fruit. In total, 33 anthocyanins were identified in the grape juice. For the first time, peonidin-3-p-coumaroyl glucoside-5-glucoside was identified in “Isabella” juice.

The results of this study validated US treatment as a simple and effective physical method that can be used as an alternative technology for improving the general quality of products such as juice by increasing the pigment concentrations that are linked to the colour and antioxidant potential of drinks. Moreover, the results demonstrate that US treatment may be less effective in the case of a sample with distinct phenolic maturation.

In the present-day context of a sharp decrease in economic and ecological resources, planned conservation and community empowerment are key strategies for sustainable heritage management, because of their cost effectiveness, increased preservation of authenticity and socially development. However, there are still very few practical implementations, so the purpose of this paper is to present applied research to real case studies, as well as to demonstrate that preventive-planned conservation is increasingly successful when linked with the empowerment of local communities and users.

This paper proposes a methodology that focuses on two complementary aspects: planned conservation (material component) – undertaken directly on buildings, through inspection, monitoring, maintenance and repair activities; community empowerment (intangible component) – afforded indirectly to users, through participatory strategies and training in prevention, maintenance and use.

Based on an estimation of costs, this paper suggests that preventive-planned conservation strategies (pre-damage) can be one-third cheaper than the reactive and interventionist approach (post-damage). Moreover, this study also develops innovative ICT tools for the planned conservation of the built heritage, namely a specifically designed computer software/App (“MPlan”) that can be used to compile maintenance plans.

The case studies are among the first applications of preventive-planned conservation strategies to the built heritage in Portugal. Different types of case studies are provided to better illustrate the methodological approach adopted and the results obtained. Special attention is given to the Romanesque Route, a cultural itinerary with 58 monuments (monasteries, churches, bridges, towers and a castle). illustrated manuals contribute to the empowerment of local communities and users.
