“…Similar results were found in a recent study performed with “Arbequina” olive oil under water stress during the whole season, where the polyphenol profile and the AA improved with the water deficit (Sena‐Moreno et al, ). In this way, there are previous evidences that tree water status is inversely correlated with polyphenols content in olive oil (Servili et al, ).…”

Three new regulated deficit irrigation (RDI) treatments were applied to "Arbequina" olive orchards during pit hardening. Oil quality was determined by measuring analytical parameters for olive oil grading, antioxidant activity, total phenol content, fatty acid profile, volatile compounds profile, and sensory analysis. Oils from RDI were classified as "extra virgin olive oil" and their quality was improved due to their higher antioxidant potential (ABTS + [increased~75%] and DPPH˙[increased~25%] assays) and phenols (increased~53%) than control. Concentration of total volatile compounds decreased (~27%) but RDI olive oils showed a more balanced profile (alcohols, aldehydes, and esters). Monounsaturated fatty acid content increased (~5%) and atherogenic and thrombogenic indexes decreased (~8.5%) in RDI olive oil. Regarding sensory analysis, RDI provided more balanced oils with higher fruit aroma than control. Other benefits of RDI olive oil, when compared with oil from full irrigated orchards are reduced use of water and improved functional and sensory quality.

“…A decrease of the concentration was found in P3 for B2. In a previous study performed applying deficit irrigation during all season, polyphenols increased in olive paste as the severity of the applied stress was increased, increasing, for instance, oleuropein, verbascoside, and flavonoids . In our study, the highest changes in the content of polyphenols were found on the iridoid family.…”

“…25 The lower decrease in some of the antioxidant capacity assays (specially FRAP) compared to TPC loss in both experiments could be explained as a result of the intermediate stage compounds, which were not polyphenols. 26 In this study, a severe irrigation deficit for a short time (A2) and a severe irrigation deficit for a long time and in phase II (pit hardening) (A3) induced a lower content of total phenols; however, other authors 24 found a higher content of total phenols in olive paste with severe water stress. These differences may be mainly due to the genetic component and stage of development of the fruit in which the water deficit is applied.…”

Reducing water consumption on agriculture is a worldwide goal toward sustainability. In this scenario, two experiments of regulated deficit irrigation (RDI) were carried out on olive trees, cultivar Manzanilla. With regard to experiment A, three RDI techniques were applied during the olive pit hardening period (stage II), while in experiment B, two RDI treatments were applied during the rehydration phase (stage III). Table olives under RDI are so-called hydroSOStainable. The effect of water deficit and Spanish-style processing was studied on the polyphenol profile, antioxidant capacity, and total polyphenol content (TPC) of both raw olives (RO) and table olives (TO). The TPC decreased after processing of TO. It could be due to osmotic mechanisms. However, many individual polyphenols, such as oleuropein (main polyphenol) or oleoside diglucoside, increased their concentrations in hydroSOStainable TO. Additionally, the TPC content was correlated to the phenological stage of the fruit when the stress is applied. A moderate stress during pit hardening and an intense stress during the rehydration phase were the treatments that best improved the polyphenol profile.

“…Several products from olive trees under RDI are being studied as hydroSOStainable ; for instance, “Manzanilla” table olives have been studied [11,12,13]. Arbequina olive oil under water deficit techniques have been previously studied [14,15,16,17,18], but there is not a clear trend on the effect of irrigation on its quality. At this time, there is not a systematic body of knowledge considering agronomic practices, phenological stage during RDI, climatic constraints, etc.…”

Quality Attributes and Fatty Acid, Volatile and Sensory Profiles of “Arbequina” hydroSOStainable Olive Oil

et al. 2019

View full text Add to dashboard Cite

The use of deficit irrigation techniques on olive orchards is the main trend aiming to optimize water savings while improving functional and sensory characteristics of oils from trees under deficit irrigation techniques. The brand hydroSOStainable has been defined for crops produced under water restriction conditions. HydroSOStainable olive oils obtained under two new regulated deficit irrigation and one sustained deficit irrigation treatments in “Arbequina” olive trees were evaluated by analyzing quality parameters, antioxidant activity, total phenol content, fatty acid profile, volatile compounds, and sensory descriptors. Results showed that some of these irrigation strategies improved the phenol content at “moderate” stress levels, slightly enriched the fatty acid profile (~3.5% increased oleic acid and simultaneously decreased saturated fatty acids), and increased some key volatile compounds and also several key sensory attributes. Therefore, hydroSOStainable olive oil may be more attractive to consumers as it is environmentally friendly, has a higher content of several bioactive compounds, and has improved sensory characteristics as compared to control (fully irrigated) oils.
