Treated and untreated capillaries with different effective lengths as wellas separation media at different pHs were tested. For that purpose, samples andstandard solutions were prepared in 25:75 ACN–water media containing 0.3% v/vacetic acid. The use of an untreated capillary of 50 cm effective length together with an80 mM borate buffer (pH 8.5) modified with 20% v/v ACN and UV detection at 254 nmwere the conditions working the best. These conditions enabled the determination ofsoybean proteins in gluten-free dietary commercial products elaborated with soybeanprotein and/or soybean flour and rice flour using the standard additions calibrationmethod. The method was linear up to 26 mg/mL of soybean proteins, the precision(expressed as RSD) was always better than 6%, and recoveries obtained for soybeanproteins when spiking commercial products were very close to 100% PB John Wiley & Sons SN 0173-0835 YR 2006 FD 2006 LK http://hdl.handle.net/10017/1358 UL http://hdl.handle.net/10017/1358 LA eng NO Ministerio de Ciencia y Tecnología DS MINDS@UW RD 20-abr-2024
