葡萄籽超微粉在模拟人体肠胃环境中的吸收状况

Absorptive Situation of Grape Seeds Supermicro Powder in Simulated Stomach and Intestinal Circumstance

葡萄籽含有丰富的生物活性成分,具有极高的营养价值和保健作用。为了充分利用葡萄籽中的功能性成分,提高产品的附加值,将超微粉碎技术应用于葡萄籽的加工中,生产葡萄籽超微粉产品。为评价葡萄籽超微粉在人体中的吸收利用状况,做模拟肠、胃环境的吸收试验。试验结果表明:葡萄籽超微粉经模拟胃液消化3～5h,多酚、白藜芦醇溶出率:霞多丽60.87%～67.43%、23.65%～40.64%,赤霞珠60.48%～69.99%、20.63%～43.38%;经模拟肠液消化5～15h,多酚、白藜芦醇溶出率:霞多丽1.96%～17.86%、17.51%～50.25%,赤霞珠3.38%～15.23%、14.02%～44.71%。葡萄籽多酚物质的消化吸收主要集中在胃环境中,白藜芦醇在肠、胃环境中的消化吸收几乎各占一半。

Grape seeds contain abundant active components,which have high nutritional and heath care value.In order to be useful grape seeds for increase new value-added products,the technology of super grinding was applied in the process of grape seeds and created a new products-supermicro powder of grape seeds.for the sake of evaluation the products,the absorptive experiment of the supermicro powder in simulated stomach and intestinal circumstance was carried out.The results were shown：After supermicro powder of grape seeds digested in simulated stomach juice for 3～5 h,the dissolved rate of polyphenols and resveratrol,Chardonnay were 60.87% ～67.43%,23.65% ～40.64% respectively;Cabernet Sauvignon were 60.48% ～69.99%,20.63% ～43.38%,respectively;digested for 5 ～15 h in simulated intestinal juice,Chardonnay were 1.96%～17.86%,17.51%～50.25%,respectively;Cabernet Sauvignon were 3.38%～15.23%,14.02%～ 44.71% respectively.It indicated that a majority of polyphenols and almost half of resveratrol of grape seeds were mainly dissolved in simulated stomach circumstance,and the others was dissolved in simulated intestinal circumstance.
