“…As a result, the effect of the label cannot be separated from the additional information given about the production methods; thus, this type of experiment is not appropriate for the estimation of the isolated OLE. The studies by Magnusson et al [29], Štefanić et al [30], Cicia et al [31], Arvanitoyannis et al [32], Ward et al [33], Krystallis et al [34], Batte et al [35], Kim et al [36], Padilla-Bernal and Pérez-Veyna [37], Akgüngör et al [38], Wang et al [39], Annunziata et al [40], Weibel et al [41], Haghjou et al [42], Hamzaoui-Essoussi and Zahaf [43], Kai et al [44], Klöckner et al [45], Lillywhite et al [46], Zanoli et al [47], Huang and Lee [48], Cerda et al [49], Hasselbach and Roosen [50], Becker et al [51], Silva et al [52], Zhou et al [53], Anisimova et al [54], Asioli et al [55], Study 1 by Besson et al [56], Bhattarai [57], and Denver et al [58] should also be excluded from the current analysis, as they have a similar problem in isolating the OLE. Although, here, the assessors did not receive any additional information about the production methods, they were asked to fill in a questionnaire or answer interview questions about organic food products.…”
