Abstract

Purpose

This study aims to evaluate the effect of adding oregano and clove oil-in-water (O/W) nanoemulsions on the physico-chemical, technological and microstructural properties of minimally processed salad dressings during storage at 8 °C and 25 °C.

Design/methodology/approach

Samples were formulated with either free or encapsulated oregano and clove essential oils in O/W nanoemulsions.

Findings

Noticeable differences in the physical stability and microstructure of salad dressings were observed after 11 storage days and were less marked for the samples formulated with encapsulated oregano or clove oils in the O/W nananoemulsions. Moreover, rheological measurements revealed minor changes in the viscoelastic characteristics of the salad dressings containing the O/W nanoemulsions.

Originality/value

These findings confirm the potential of oregano and clove O/W nanoemulsions for use in minimally processed salad dressings as stabilising and technological agents.

Abstract

Purpose

The purpose of this paper is to estimate the impact of the 2008 and 2020 economic crises on employment in Spain.

Design/methodology/approach

The authors perform a counterfactual analysis, combining intervention (interrupted time series) analysis and conditional forecasting to estimate a “crisis-free” scenario. These counterfactual estimates are used as a synthetic control, to be compared with the observed values of the main variables of the Spanish Labor Force Survey (EPA).

Findings

The authors measure the effect on Spanish employment of the 2008 recession and the ongoing COVID/Ukraine crisis and the speed of recovery, which yields a rigorous dating for the beginning and end of the crises studied. Finally, the authors provide estimates about which part of the employed and unemployed people was in furlough (ERTE) based on microdata provided by the Spanish Institute of Statistics.

Originality/value

To the best of the authors’ knowledge, there are no counterfactual studies covering all the basic variables in EPA and no estimates for the effect of ERTEs on the basic employment variables. Finally, the authors combine well-known intervention and forecasting techniques into an integrated framework to assess the effects of both, past and ongoing crises.
