- Abstract: Se determinó el contenido del lignano antioxidante (Sesamol) en sésamo, formulaciones comerciales de tahina y halva, que es el producto procesado de tahina, por polarografía de pulsos diferencial (DPP) con un capilar conteniendo un electrodo de gota de mercurio (HMDE). Un hilo de platino fué usado como el electrodo contador y Ag/AgCl como electrodo de referencia. Las muestras fueron analizadas por procedimientos de adición de patrones y se encontró que wl procedimiento era cuantitativo (p< 0.01). Debido a que el sesamol es un compuesto fenólico soluble en aceite, se estudiaron los porcentajes de aceite en sésamo, tahina y halva. Las muestras de sésamo contenían un 51.05-56.46 % de aceite mientras que la muestras de tahina tenían un 52.12- 53.79 % de aceite. Se encontró que el porcentaje de aceite de halva fue un 28.79-30.13 % (p< 0.01). El sesamol encontrado en el sésamo fue de 0.26-0.32 mg/100 g de aceite, mientras que el sesamol en tahina fue de 10.98-12.33 mg/100 g de aceite. El sesamol de muestra de halva de procedencia comercial diferente varió entre 8.24-9.12 mg/100 g de aceite y 4.97 mg sesamol/100 g de aceite, respectivamente (R2= 0.9999) (p< 0.01). El método polarográfico propuesto (DPP) es un método rápido y reproducible para la determinación simultánea de lignanos fenólicos en sésamo y otros productos alimentados que contienen sésamo. Éste proporciona una detección cuantitativa adecuada y sensible de este compuesto nutraceútico en alimentos comerciales. [ABSTRACT FROM AUTHOR]
- Abstract: The contents of sesamol and related lignans in sesame, tahina and halva as determined by a newly developed polarographic and stripping voltammetric analysis. The contents of antioxidant lignans (Sesamol) in sesame, commercial formulations of tahina and halva, which are processed tahina foods, were determined by Differential Pulse Polarography (DPP) with a capillary hanging mercury drop electrode (HMDE). A platinum wire was used as the counter electrode and Ag/AgCl was the reference electrode. Samples have been analyzed by standard addition procedures and found to be quantitative (p<0.01). Due to the fact that sesamo is an oil-soluble phenolic compound, it was found in the oil levels of sesame, tahina and halvas. Sesame samples contained 51.05-56.46 % in oil whereas tahina samples contained 52.12-53.79 % in oil. The oil percentage of plain halva was found to be 28.79 - 30.13 % (p<0.01). Phenolic lignan sesamol in sesame was 0.26-0.32 mg/100g oil, whereas the sesamol in tahina was 10.98-12.33 mg/100g oil. The sesamol in commercial plain halva samples and the open marketed plain halva samples contained 8.24-9.12 mg/100g oil and 4.97 mg sesamol /100g oil, respectively (R²=0.9999) (p<0.01). The proposed Differential Pulse Polarographic (DPP) method is a rapid, reproducible procedure for the simultaneous determination of phenolic lignans in sesame and food products with sesame. It provides an adequate, sensitive, quantitative detection of these nutraceuticals in the commercial food industry. [ABSTRACT FROM AUTHOR]
