BENAVIDES, Magda Vieira; KLEIN, Wanderney  e  FIGUEIRO, Paulo Roberto Pires. EFFECTS OF THE ANALYSIS METHODOLOGY ON SUINT CHARATERISTICS WAX PERCENT AND SCOURED WOOL COLOUR (Y-Z). Cienc. Rural [online]. 1993, vol.23, n.2, pp.209-214. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84781993000200017.

Wool samples from various fleeces regions of Polwarth and Corriedale hogget ewes were analysed following two different sequences in order to record wax and suint percents, suint colour and pH and scoured wool colour. In the first method, the wax was extracted before the suint (Wax + Suint) and the second extracted suint before wax (Suint + Wax). The wax percent was greater to Wax + Suint method (P < 0.001) (both to two breeds). To the Corriedales, the suint percent was greater to Suint + Wax method (P < 0.05). The wool brightness (Y) differed between methods only to Corriedales, there was brighter to Suint + Wax and this method showed a bias (P > 0.05) into a smaller yellowness index (Y-Z). The correlations between characteristics within methods recorded medium values.

Palavras-chave : yolk extraction; scoured wool colour; methodology.
