Quality attributes of table olives as affected by regulated deficit irrigation

Abstract

preprint© 2015 Elsevier Ltd. Regulated deficit irrigation (RDI) allows us to decrease the amount of water to apply without significantly affecting yield and fruit quality. The influence of 3 irrigation treatments [T0: control (no stress); T1: moderate stress during pit hardening; and, T2: low stress at the end of flowering stage and moderate during pit hardening) on the quality of table olives, cv. '. Manzanilla', was evaluated. The parameters evaluated in table olives (after processing) were: weight, size, texture, color, fatty acids, volatile compounds and sensory quality. T1 olives had the highest weight and size, and were rounded. Color coordinates L* and b* had the highest values in T2 olives. Aldehydes and monounsaturated fatty acids predominated in T0 olive fruits, while terpenes and polyunsaturated fatty acids predominated in T1 fruits, and finally saturated fatty acids were abundant in T2 olives. Finally, the results of sensory studies indicated that global acceptance was higher for T1 olive, obtaining better satisfaction degrees for fresh olive flavor, crunchiness, and global satisfaction. Deficit irrigation is effective and can be a good alternative for this type of crop, '. Manzanilla' table olives.(Ministerio de Economía y Competitividad, Spai

Effects of irrigation treatments on the quality of table olives produced with the Greek-style process

“…Interestingly, drupes of trial T50 showed values of carpological measurements similar to that registered for trial T100. Cano-Lamadrid et al (2015) also observed the highest equatorial diameter in fruits submitted to irrigation during stone hardening. Similar results were reported by Proietti and Antognozzi (1996) and Aponte et al (2012) for olives harvested from irrigated trees.…”

“…Cano-Lamadrid et al (2015) also observed positive effects on the quality and consumers' satisfaction degree of table olives from moderate irrigation. In contrast, Aponte et al (2012) did not show significant differences among samples coming from irrigated and not irrigated groves, a result imputable to the action of the LAB strains added as starter culture.…”

Sensory and physico-chemical quality attributes of jujube fruits as affected by crop load

“…Basically, 0.5 g were digested using HNO 3 at temperature below 140 C. Quantification was conducted in a Unicam Solaar 969 atomic absorption-emission spectrometer (Unicam Ltd., Cambridge, U.K.). A certified reference material (GBW07603) was used to ensure the goodness of the analytical protocol (Cano-Lamadrid et al, 2015). Analyses were run in triplicate.…”

Antioxidant capacity, fatty acids profile, and descriptive sensory analysis of table olives as affected by deficit irrigation

“…Table olives cultivated under RDI conditions are considered as ‘hydrosustainable’ products, and have a solid identity (higher contents of essential components, higher intensity of key sensory attributes, etc. ); besides, they can be a good alternative for this type of crop and reduce the economic and environmental costs linked to irrigation, optimising the use of a very valuable resource in the world, water …”
