Differences of A.R.% of specific aroma compounds were observed also between the candies added with the strawberry natural (NS, Table 4A) or nature-identical type (NIS, Table 4B), likely affected by their different relative concentration in the pure flavouring. i.e. Ethyl acetate showed an A.R.% < 4% for the NS added candies while it was >90% for the NIS flavoured candies. Since candies were prepared according to the same protocol for each thickening agent, this could be the result of potential interactions with the no volatile compounds, (possibly concentration-dependent),
and the effect of the other volatiles in the flavouring mixture that may could have differently affected their solubility and retention in the matrix during the candy manufacturing and/or analysis.
