Study on precision of a DNA analysis method for quantifying cashmere/wool mixture

摘要

Cashmere is a kind of luxury fiber fine in texture, strong, soft and light. Garment made from it is quite expensive due to its excellent performance and rareness. Thus adulteration and false declaration occurs quite often in industrial chain. We have developed a DNA analysis based method for quantifying cashmere/wool mixture. The goal of the paper is to evaluate the precision of method. Three commercially available woven products claimed to have contained different content of cashmere were employed to finish our tests. Six laboratories with correspondent qualifications were invited to do the texts. Result of data analysis shows DNA analysis is an useful and accurate method for determining the content of cashmere in a cashmere/wool mixture.
