Seleção De Julgadores E Avaliação De Diferença Sensorial Entre Extratos Hidrossolúveis Da Amêndoa Da Castanha De Caju (Anacardium Occidentale L.)

Abstract

The triangle test was applied with 12 selected judges to verify significant difference (p≤0,001) in the use of broken cashew nut almonds classified as splits, butts and pieces, all of them type 1, as raw material to produce an hydrosoluble extract. The samples had been produced triturating cashew nut almonds with different ratios of mineral water. In the selection of judges stage the ratios of almonds:water had been 1:6, 1:8 and 1:10 and for the discriminative test this ratio was 1:8, having difference enters among samples only in relation to the cashew nut almonds classification. The samples had been packed in polyethylene packages, pasteurized and stored under refrigeration. The selection of judges was carried through triangle test. The results had been evaluated statistically by the sequential analysis of Wald, according to graphical method. The decision was based on the test of hypotheses: H0: P1≤p0; H1: p1> p0, and used the values p0=0.33, p1=0.66, for the risks 〈=0.05 and ß=0.05. In the evaluation of significant difference (p≤0.001) through the triangle test, the almonds classified as splits and butts of type 1 did not present difference, but differed from the almonds classified as pieces of type 1. In view that almonds classified as pieces have a minor percentile of integrity that the others, being thus more susceptible to the lipid oxidation, is indicated the use of splits and butts for the hydrosoluble extract production.
