霞多丽葡萄籽提取物
摘要：
一种新的葡萄籽提取物，其富含原花青素类化合物，具有低于70％的总多酚类化合物，并具有低的聚合度(dp)。所述提取物的其他级分具有极少的多酚类化合物、纤维和蛋白质，但含有超过90％的糖类。在一些特定实例中，通过所述葡萄籽的水提取物的连续超滤获得各个提取物。第一次超滤提供可用作调味剂的富含糖类的第一透过物(级分A)和第一渗余物。将所述第一渗余物重构并以更高的截留分子量进行第二次超滤，以产生富含低分子量多酚类化合物的第二透过物(级分B)和富含葡萄籽纤维的第二渗余物(级分C)。所述级分单独地适合于不同营养品，或者可以以任何组合方式彼此组合和/或与其他营养剂组合，以提高血管和认知健康。
摘要（英）：

A novel grape seed extract is enriched in procyanidins, has total polyphenols of less than 70%, and has a low degree of polymerization (dp). Other fractions of the extract have minimal polyphenols, fiber, and protein, but contain more than 90% sugars. In some specific examples, the individual extracts are obtained by sequential ultrafiltration of a water extract of the grape seeds. A first ultrafiltration provides a first permeate (Fraction A) enriched in sugars which is useful as a flavorant, and a first retentate. The first retentate is reconstituted and subjected to a second ultrafiltration at a higher molecular weight cutoff to produce a second permeate (Fraction B) that is enriched in low molecular weight polyphenols, and a second retentate (Fraction C) that is enriched in seed fiber. The Fractions are individually suitable for different nutraceutical products, or can be combined with each other in any combination and/or with other nutraceutical agents to enhance vascular and cognitive health.
